What are the common senses that should be paid attention to in oil fume purifiers?

1. The purification efficiency of low-altitude fume fume purifier is higher than that of high-altitude fume purifier.

2. Low-altitude oil fume purifier refers to an electrostatic oil fume purifier with a purification efficiency of more than 90%.

3. Electrostatic oil fume purifiers are mainly divided into honeycomb type and plate type.

4. Low-altitude oil fume purifier** is generally more than 2000 yuan.

5. When purchasing a fume purifier, it is best to choose a powerful manufacturer or brand, and the after-sales service can keep up.

6. The oil fume purifier must be grounded.

7. The selection of the air volume of the fume purifier is mainly based on the number of stoves and dishes, the more fumes, the greater the air volume of the equipment.

8. The oil fume purifier should be installed horizontally to prevent oil leakage, and if it is suspended, a firm and stable bracket should be made.

9. If it is installed outdoors, a rainproof device should be installed.

10. Sufficient space should be left for door opening during installation.

11. The interface between the purifier and the smoke exhaust pipe must be sealed.

12. The outlet pipe should not be too long, and should be within 2 meters.

13. Turn on the fume purifier first, and then turn on the gas stove, generally 1-2 minutes in advance.

14. Turn off the fume purifier after turning off the gas stove for 3 minutes, so as to ensure that the air is fresh.

15. The discharge sound emitted by the equipment is normal operation.

16. The occasional discharge sound of "pop, pop" of the equipment is also a normal phenomenon, and if it is too frequent, it is a failure.

17. The oil fume purifier should be cleaned regularly, otherwise the purification efficiency will be reduced.

18. The cleaning of large oil fume purifiers must be operated by professionals, ** varies from region to region, generally in the range of 150 yuan - 400 yuan.

19. Always check whether the oil drain pipe is normal to avoid oil pipe blockage.

20. If the equipment is idle for a long time, it should be placed in a dry and ventilated place.

Prepare tools: protective gloves, insulating screwdriver, container that can hold electric field, special cleaning agent, high-pressure water gun, hot water at about 50 degrees.

Step 1: Turn off the power and remove the electric field.

After turning off the power of the equipment, open the door of the equipment box after a few minutes to expose the electric field, and use an insulating screwdriver to touch the surrounding area of the electric field to release the residual charge on the plate. Take out the electric field smoothly with both hands to avoid damage to the electric field by rethrowing, squeezing and other actions.

Step 2: Soaking, rinsing, and drying.

Configure the cleaning solution in the container according to a certain proportion of cleaning agent and water, put the electric field into the soaking, the cleaning solution is best completely submerged in the electric field, the soaking time is about 15 minutes, and the soaking time should not be too long, so as not to corrode the electric field of the cleaning solution; When soaked, take out the electric field and rinse it with a high-pressure water gun; Finally, the electric field is left to dry.

Step 3: Assemble it back step by step.

After the electric field is dried, observe whether there are impurities or deformation in the electric field, if necessary, slowly restore the electric field or remove impurities, and finally install the electric field back into the chassis according to the steps.

Note: When cleaning the electric field, the filter and insulator of the device can be cleaned and replaced if these two parts are damaged or difficult to remove grease.

What are the features and functions of the oil fume purifier? What are the precautions?

The oil fume purifier improves the removal efficiency of oil fume purification.

It is mainly used for the purification and treatment of low-altitude emission fumes in the kitchen;

It is used in hotels, restaurants, restaurants, restaurants, schools, institutions, factories and other places;

food frying, cooking and processing industries; Oil splash heat treatment workshop

Oil mist lubrication workshop, workpiece welding workshop and olefin oil boiler discharge and other industrial occasions.

1.A simple hood is used to collect the fumes and exhaust them to the outside through the exhaust fan.

Only the fume is collected, no purification is done, and the removal rate of the fume is 0%.

2. The lye solution is used as the detergent, and the fume is purified by spraying in contact with the fume, and then collected and discharged through the exhaust fan.

3. Water spray scrubber purification process.

The fume hood is collected and sent to the absorption tower (spray, sieve plate, packing) for purification, and then discharged through the exhaust fan.

The first point is to clean the purifier equipment in time. Under high temperature, when the oil fume purifier is used for a long time, a large amount of oil and dirt will accumulate inside, and these grease and dirt will affect the purification efficiency of the purifier even more; In serious cases, it will also damage the internal equipment of the purifier and reduce the service life.

The second point is to prevent grease leakage. Oils and fats are difficult to maintain in a solid state at high temperatures and are mostly presented in a liquid state. Liquid grease is easy to contaminate the kitchen in a large area, so when using the fume purifier, you need to pay attention to hygiene, do not ignore the cleaning of the pipe and kitchen stove grease, check the air tightness of the fume pipe, prevent grease leakage, and replace the oil collection tank of the cleaning fume purifier in time.

The third point is to prevent fire accidents. According to the research, it was found that most of the restaurants caught fire because of the fume purifier, and the most frequent season is summer.

This is because as the temperature rises, grease, as a flammable substance, can easily induce fires in the event of an open flame. Therefore, for the sake of safety and property protection, merchants need to be on guard at all times!

1. When using the fume purifier, press the start button first, let the fume purifier start to work, and then light the stove to form an air flow in advance and smoothly discharge the fume and fuel exhaust gas.

2. When frying, frying, and frying food, take good care of the fume purifier, and try to avoid sparks being sucked into the fume purifier and burning the internal parts.

3. When using high-pressure cookers, when opening the safety valve, the fume purifier should be turned off in time to prevent the ejects from being inhaled into the machine.

4. When the fume purifier is running, do not reach out to test the air volume at the air inlet, so as not to hurt your hands by the fan blades.

5. When the fume purifier is not used, turn off the power supply and unplug it to avoid shortening the service life of the fume purifier.

Precautions for cleaning and maintenance of oil fume purifier.

1.Use the fume purifier for as long as possible.

After the fume purifier is started, the use time should be extended as much as possible, and it should not be opened and closed frequently, so that the service life of the fume purifier will be shortened, and the power consumption of the fume purifier itself will not be very large.

2.Clean and maintain the fan regularly.

In our daily life, after using the fan for a long time, we will find that the fan blade has a layer of black and black things, which greatly affects the air volume and appearance, and the same is true for the fan. If the fan impeller is not cleaned, a thick layer of dust will accumulate, resulting in a decrease in wind rate, affecting the purification efficiency, and even crashing. It is necessary to frequently check whether the fan and the purification exhaust pipe are smooth, and replace the lubricating oil for the fan regularly.

3.Regularly drain the oil and clean the dirt from the oil fume purifier.

Under the long-term operation of the equipment, a lot of oil will accumulate, the bottom valve should be opened regularly to discharge the dirty oil of the equipment, and scrub some oil dirt on the surface of the oil fume purifier to avoid the erosion of oil dirt on the parts of the oil fume purifier, affecting the purification efficiency and service life.

4.Regularly clean and maintain the electric field of the oil fume purifier.

Most of the electrostatic fume purifiers on the market can be divided into plate electric field and honeycomb electric field, and the cleaning methods and cleaning cycles of different electric fields are also different. The cleaning cycle of plate electric field is generally about 1 month, and the cleaning cycle of honeycomb electric field is generally about two months. We need to carry out regular cleaning and maintenance according to the cleaning methods provided by the oil fume purifier manufacturer, which can effectively extend the service life of the purifier equipment.

When cleaning and maintaining the fume purifier, all power should be turned off, and for safety, the high-voltage part of the equipment should be opened by professional maintenance personnel for disassembly and debugging.

Precautions for installation of oil fume purifier.

1.There are different models of oil fume purifiers, and the air volume of different types of purifiers is also different, so it is necessary to ensure that the ventilation volume in the purification system is within the treatment range of the purifier.

2.The wind speed in the pipeline should be designed at 11-12m s, and the radius of the center line of the elbow is =.

3.To ensure that the oil fume purifier is installed horizontally, the purifier must be reliably grounded (the purifier has three outgoing wires, the red line and the green wire are connected to 220V AC, and the yellow and green wires are grounded).

4.The angle between the hypotenuse of the reducer (small to large) and the axis <=70 degrees, and the angle between the hypotenuse and the axis of the reducer (large to small) is <=15 degrees.

5.The fan needs to install a shock absorber, the inlet and outlet air duct connection needs to be installed with a soft connection, the inlet of the fan should retain a 1-2 meter straight pipe section to reduce the additional resistance of the fan, and the fan needs to be installed behind the fume purifier to ensure the purification efficiency of the fume purifier.

6.For the fume purifier installed outdoors, even if the fume purifier itself is made of material that can prevent rain and sun, long-term exposure to the sun and rain will definitely accelerate the aging of the purification equipment, so it is necessary to install an awning that is rainproof and sun-shading.

It is necessary to pay attention to daily maintenance and maintenance, such as regular cleaning, to maintain the purification effect of the equipment.

Precautions for the use of oil fume purifier:

1. It needs frequent cleaning and maintenance. If it is not cleaned for a long time, it may cause the oil circuit to be blocked, and then the waste oil will accumulate, the motor load will increase, and the motor will burn out in serious cases. The flue is narrow or the smoke exhaust pipe is too long, resulting in large suction and small displacement, and the two are disproportionate, so that the residual air circulation in the wind silo is intensified, causing the whole machine to shake and make great noise.

2. Do not use a moist rag and sliding detergent to wipe the range hood switch when cleaning, as long as the oil circuit is unblocked, and it is best to need professionals to clean it.

3. If it is a large-scale fume purifier product, it must need professionals to clean, and the larger equipment is in hotels, restaurants, canteens and other places, and the purifier is not only conducive to smooth kitchen smoke exhaust, but also can eliminate fire hazards.

Note that:

The fume purifier needs to be cleaned every 2 months.

During use, you need to observe the running status of the equipment, and if the fault is displayed, you must turn off the power switch in time.

Do not touch the device in operation.

If the equipment needs to be repaired, first contact the installer to inquire.

If the fume purifier is not in use, it can be turned off.

Precautions in the use of oil fume purifier:

1. A three-prong power socket must be configured, and its grounding electrode must be connected to a reliable grounding wire.

2. The outlet of the smoke pipe should be avoided in the windshield, so as not to affect the emission of the flue gas due to the strong wind outside, and the smoke exhaust pipe is strictly forbidden to be connected to the hot flue.

3. Minimize the convection of kitchen air.

4. When the fume purifier is running, never touch the fan with your hands, let alone insert it with a hard object.

5. When using the oil pan, it must be carefully taken care of to prevent the flame from being put into the machine.

6. When using the pressure cooker to cook, if the safety valve is broken, the fume purifier should be closed in time to prevent the ejects from being injected into the machine.

Precautions for cleaning and maintenance of oil fume purifier:

1. When cleaning the fume purifier, the power supply should be cut off, and it is strictly forbidden to clean the fume purifier with electricity.

2. The gas sensor should be removed and cleaned every half a month.

3. To clean the oil stain on the surface of the casing, you can clean it with a soft cloth dipped in neutral cleaning solution.

The working procedure of oil fume purifier cleaning:

1. Disassemble the cleaning parts: first cut off the power supply of the range fume purifier and remove the oil fume purifier from the hoisting position, then disassemble the oil fume purifier and take it out in turn: lighting bulb, oil collection box, bottom plate, sealing ring, impeller.

Finally, the inner core of the fuselage is proposed.

2. Soak the cleaning parts: find a larger container, pour in the cleaning liquid, and place the removed parts to soak. The amount of cleaning solution should not be too small or too much, and the cleaning parts that can be soaked shall prevail. Large items should be wiped.

Rinse with a cloth dampened with cleaning solution. The soaking time of the cleaning parts is determined according to the degree of oil stain, generally 15 to 20 minutes.

3. Brushing dirt parts: the oily parts after soaking are relatively easy to clean, and they can be cleaned by repeated cleaning with iron brushes and brushes dipped in cleaning liquid. However, the oil fume purifier with serious oil pollution should take special cleaning measures.

Wash well. The usual method is to first use a flat-headed snatcher and other tools to snatch off the thicker oil stain, and then soak it, and then use caustic soda water to scrub the serious oil stain, and must wear rubber gloves when brushing to prevent caustic soda.

Burn**.

Based on my experience over the years, I have come to the following conclusions, I hope it will be helpful to you!!

1.Make sure to cut off the power supply first and thus ensure the safety of the cleaning staff.

2.Find a professional environmental protection company for cleaning, and professional personnel will be more careful when taking out the electrode to prevent the deformation of the electrode, which will affect the discharge.

3.For non-anti-corrosion kitchen fume purifiers, try to choose hot water to rinse to avoid corrosion of the fume purifier by cleaning agents.

4.After cleaning, wipe the electrode dry to avoid immediate use, and the insulation is not good.

5.For kitchen fume purifiers with filter layers, the filter layer should be replaced or cleaned regularly.

6.For kitchen fume purifiers with activated carbon filter layers, the activated carbon should also be replaced regularly.

7.For insulating ceramics (insulators), the cleaner the wipe, the better.

First, canteens, hotels and canteens should conduct regular fire safety education for their staff, formulate corresponding fire safety management guidelines, and regularly inspect gas fuel pipes, flange fittings and valves in kitchens to detect gas fuel leaks in a timely manner.

Second, standard natural gas, oil, electricity. Tank liquefied petroleum gas (LPG) should not be used in kitchens in high-rise buildings. Natural gas and gas pipelines should be imported from the outside separately and should not pass through guest rooms and other public places.

Gas cylinders in the kitchen should be clustered together and separated from open flames or high-temperature appearances such as lamps and lanterns to prevent high-temperature baking and gas cylinders**. Kitchen stoves should be installed on non-combustible materials and should be spaced sufficiently from combustible materials to prevent combustible materials from combusting.

Third, key components should be sorted and cleaned regularly. Walls next to kitchen stoves, hoods and other simple contaminated places should be cleaned daily, as should the smoke pipes be cleaned regularly. The kitchen should be equipped with some cotton blankets to extinguish all kinds of tank fires.

The kitchen can also be equipped with a certain number of ABC dry powder fire extinguisher equipment and should be placed in a prominent position in case it is needed in a timely manner.

Fourth, make an electric fire valve on the exhaust pipe. When the temperature is higher than the extra temperature of the fire valve, the electrical fire valve will actively close, so that the smoke of the pipe cannot reach the ignition point, and the fire can also be reduced. Fifth, the distance between the fume purifier and the collection smoke screen should not be too close.

Only by taking preventive measures can we avoid the occurrence of oil fume purifier accidents.

Before choosing a kitchen fume purifier, we must first understand the local application of the product. You can ask the manufacturer to provide multiple application engineering examples nearby (make sure you have multiple options and choose an instance similar to the situation in your own restaurant). Don't listen to the manufacturer's words unilaterally, choose the peak on-site observation of the restaurant (in order to prevent the purchase of fake and shoddy products, wasting thousands of yuan or even tens of thousands of yuan, the effort of a hard meal is still worth it), if the purification conditions of the model project are met during the peak period of hotel business, and the smoke exhaust in the kitchen is smooth, it can be considered that the purification efficiency of the purification equipment is acceptable.
