Under what circumstances does the oil fume purifier need to be cleaned?

The fume purifier has problems in less than half a month, and it is generally a problem with maintenance.

As for when you need to clean, here is a quick way to tell the difference. If the fume purifier reaches the standard after installation, there is no obvious white smoke at the smoke exhaust outlet, because the fume purifier will purify the fume.

However, when the internal oil scale of the fume purifier accumulates, it will seriously affect the purification effect, resulting in a significant decrease in the purification rate, so white smoke will appear at the smoke exhaust outlet, and we can observe the white smoke to judge whether the fume purifier needs to be cleaned.

In the case that the white smoke is more obvious, the oil fume purifier can be cleaned, and the cleaning record should be made and the cleaning cycle should be formulated, which is more convenient for maintenance and cleaning.

Maybe many people think so, the fume purifier is a box, usually do not need to be dismantled and washed, in fact, there are still many fire cases caused by the fume purifier in the hotel, among which the fume purifier is not cleaned regularly is one of the culprits.

Presumably everyone knows that after the air conditioner at home has been used for a long time, the filter in the air conditioner is all dust, so it is necessary to ask the master to clean the dust regularly, or clean it up yourself, so as to prevent the breeding of bacteria and help the air conditioner dissipate heat. If you don't take the time to clean the kitchen at home for a long time, it will become full of oil, let alone a fume purifier that purifies the fumes in large hotels every day.

Under normal use, the oil fume purifier should generally be cleaned once every (3-6) months. After the equipment has been used for a period of time, the inside of the purified electric field is full of oil stains. If it is not cleaned up in time, in addition to reducing the purification effect of the fume purifier, it will also lead to substandard emissions, which is not conducive to atmospheric environment governance.

At the same time, especially now that the weather is hot, the likelihood of fires is greatly increased. Excessive oil build-up can be caused by a little spark**.

Cleaning and maintenance of oil fume purifiers.

Parts that need to be cleaned: high-voltage insulators, electric fields, and guide troughs in the chassis.

Materials to be prepared: caustic soda.

High voltage insulator cleaning method: Wipe the electric field with alcohol until it looks clean.

Cleaning steps:1Turn off the power of the purifier;

2.Unscrew the deadbolt and take out the electric field with both hands;

3.Pay attention to the position of the contacts;

4.Pour in industrial caustic soda, add 40 degrees of hot water and soak for about 15 minutes, then rinse with water for 5 minutes;

5.After cleaning, it should be dried, put back into the purifier in the original direction and start the fan to dry.

After a period of time, it is time to wash, and the 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 removal rate of oil fumes of this product is about 80-90%. The removal rate of oil smoke meets the requirements of GB18483-2001. However, the equipment installation space is large and the system is complex.

High voltage static electricity (plasma).

The ionization of the gas and the force of the electric field under high pressure are used to separate the dust particles from the gas after charging.

The fume removal rate of this product is 95% nominally. The removal rate of oil fume in the first week of use of the product is 95% in line with the requirements of GB18483-2001, and the removal rate drops in a straight line until it reaches zero after about 3 months of continuous use. If you need to ensure the fume purification effect, as well as the fume removal rate up to the standard, you must clean it every two weeks, and a professional electrostatic fume purifier cleaning service company will do it on your behalf, with a cost of 1000 to 5000 yuan each time.

If it is not cleaned according to the specifications, the oil accumulation in the smoke exhaust pipe is serious, and the risk of fire is very high.

Physical filtration. One or several types of composites such as wire mesh, activated carbon, and steel wire.

The actual removal rate of such products is 20 30%, which cannot meet the requirements of GB18483-2001 when used alone. Easy to clog and needs to be cleaned weekly.

Photocatalysis. Ultraviolet light is used to decompose the oil mist of oily gases.

The fume removal rate can reach 60%, which meets the requirements of GB18483-2001, provided that a minimum of about 30 meters of pipe is required to facilitate the installation of UV tubes. Only imported ultraviolet fluorescent tubes can ensure the reliability and durability of the product. The disadvantage is that ultraviolet light is carcinogenic, it must be sealed tightly, and ozone leaks, which does not benefit everyone.

By the way, a little leakage can be sterilized and disinfected.

Bio-decontamination. Oleophilic microorganisms are used to decompose and purify the oil mist in the oil smoke.

The removal rate of oil smoke of this product can reach 90%, which meets the requirements of GB18483-2001. A dedicated microbial pool is required, and microbial metabolism needs to be regularly processed and renewed. This treatment method is the most environmentally friendly.

Wash with liquid foam. Using the mass transfer double membrane theory, the combination of physical and chemical methods, and mechatronics products, strictly speaking, should not be called oil fume purifier, but should be called oil fume purifier is more reasonable.

The removal rate of oil smoke of this product can reach 90%, which meets the requirements of GB18483-2001. A special purifier is used to improve the dual-membrane mass transfer power between the gas-liquid phase, which can quickly capture particles such as oil smoke in the gas phase; At the same time, the negative pressure of the exhaust fan is used to generate a liquid foam layer with a thickness of about 600mm (the size and diameter of the liquid foam) are used to scrub and purify the oil smoke gas. The purification effect is equivalent to that of a natural rainfall layer of about 600 meters.

The removal rate of oil in oil smoke is 90%, the removal rate of black smoke particles is 90%, the removal rate of dust and other impurities in the air is 90%, the removal rate of various odors is 70%, and the removal rate of blue smoke (chemical gel) is 60%. The product needs to be used every 2 to 3 days to do the work of sewage and add professional purifiers. The product has stable operation, long service life and special fire resistance.

Smoke exhaust vent smoke condition.

The smoke exhaust port of the low-altitude electrostatic fume purifier is different from the high-altitude fume purifier, and the general low-altitude fume purifier smoke exhaust port can be set up in the outdoor low place for direct discharge, so the visual inspection of smoke-free at the smoke exhaust outlet is a very important indicator, that is, there is no obvious smoke at the smoke exhaust port when using the fume purifier. If you find it after a while when there is no smoke, then it means that it is time for the fume purifier to be cleaned. Smoke vents.

Ammeter readings.

The general manufacturers will install an ammeter and a working maintenance indicator on the door of the fume purifier shell, if the fume purifier is not so accurate for cleaning after long-term use, it can be judged by looking at the ammeter. If the ammeter keeps jumping or the value shown is too large, and the maintenance indicator lights up or flashing, then it is most likely that the oil fume purifier needs to be cleaned. Ammeter.

Abnormal noise of the device. There are two situations in which the oil fume purifier equipment has abnormal noise. If there is an abnormal noise when the equipment is running, and it will be gone for a while, or the abnormal noise time is relatively short, then it means that water vapor has entered the inside of the oil fume purifier, which is a normal phenomenon; If the fume purifier keeps making abnormal noises after opening, then it means that there is too much oil dirt inside the fume purifier, there are foreign bodies or deformation of the electric field, in this case, the fume purifier needs to be disassembled to deal with the internal electric field

If there is too much grease, clean it, remove foreign matter if there is foreign matter, and repair the deformation of the electric field.

Observe whether the smoke exhaust vent is visually smoke-free.

First of all, the first thing is to check the smoke from the smoke exhaust vent. We know that at present, many areas have relatively high requirements for the purification efficiency of oil fume purification equipment, and in order to meet the high requirements of purification efficiency, a relatively basic indicator to be achieved by oil fume purifier is "visual smoke-free"! If you find that there is obvious smoke coming out when you check the smoke exhaust outlet, it indicates that the purification efficiency of the purification equipment has decreased and needs to be cleaned in time.

Check the ammeter readings.

The second is to look at the ammeter readings on the door of the fume purifier's chassis. Nowadays, most oil fume purifier manufacturers will install an ammeter on the door of the equipment chassis, if you are not sure whether the equipment needs to be cleaned, you can judge by checking the ammeter. If you find that the value shown in the ammeter is too large or the beating amplitude is too large, and the red light is on, it means that the oil fume purifier may need to be cleaned.

Whether there is any abnormal noise in the device.

The third is abnormal noise during the operation of the equipment. Under normal circumstances, a quality fume purification equipment should be kept in a low noise state during operation. However, if the equipment has not been cleaned for a long time and a large amount of grease has accumulated inside, it is possible to produce other noises that are not caused by fan exhaust.

Therefore, once it is found that the oil fume purifier will produce abnormal noise during operation, it is time to clean the equipment.

The international Kuaiba oil fume purifier is basically cleaned once every 3-5 months, and you only need to turn off the power switch of the equipment and take out the electric field when cleaning. Then rinse with a high-pressure water gun, if the smoke is too large, you can add dish soap or Mr. Vermeer to clean, and you can use it normally after drying.

The range hood purifier needs to be cleaned, in the process of oil fume purification, grease, oil stains, acetic acid, water vapor and other pollutants will enter the oil fume purifier, if it is not cleaned for a long time, it is easy to erode some parts in the equipment, which will lead to a reduction in service life and easy to damage the machine.

If the fume purifier is not cleaned, the purification effect of the equipment will be reduced at this time, and the adsorption capacity of the electric field will be weakened.

In the process of oil fume purification, if it is not cleaned for a long time, a layer of black oil will be attached to the surface of the electric field at this time, resulting in the weakening of the adsorption capacity of the electric field, so the purification effect of the equipment will be reduced.

If the dirt is not cleaned for a long time, it will accumulate and it will be more difficult to clean. It's like a piece of dirt on your clothes, and if you don't wash it in time, it will be more troublesome to wash it again at this time.

Because of the total deal with oil fume, if you don't clean it regularly, it is easy to accumulate thick grease and grease, and the temperature of the current is relatively large and the temperature is relatively high, if you accidentally come into contact with sparks, it is easy to cause a fire.

In addition, it is best to clean the fume purifier regularly, otherwise the dirt accumulated inside will not be easy to clean for a long time.

1. First power off the fume purifier, and then use tools to disassemble its shell and power supply one by one, so as to avoid excessive force and deformation when disassembling.

2. Prepare a special cleaning agent, mix it with a certain amount of warm water, wipe the inside of the fume purifier with a rag, make sure that every corner is wiped in place, especially the grease on it must be scrubbed clean, and then rinse it with water several times to ensure that there is no residual cleaning agent.

3. Dry the cleaned parts to ensure that there is no moisture and then install them back.

Fume purification method:

1. Mechanical separation method.

There are many ways to purify the fume, and the more traditional method of machine separation is adopted, which is to achieve the separation of fume through inertial collision and cyclone separation, so as to achieve the purpose of purification. The purification effect of this method is relatively low, and it is not suitable for use in areas with large oil smoke, and its exhaust gas is directly discharged, which has a certain pollution to the air.

2. Catalyst combustion method.

It is also known as combustion purification method, that is, the combustion produces high-temperature oxidation to convert polluting substances, and converts them into carbon dioxide, water and other substances, so that it can be effectively purified, and its purification efficiency is not very good, and it is not suitable for use in high smoke areas.

3. Activated carbon adsorption method.

The adsorption capacity of activated carbon is good, and it has a good application in purification and filtration, which can well adsorb the flue gas and grease in the oil smoke, but because of the high cost, the application is not particularly widespread.

The cleaning method of the oil fume purifier is as follows:

Material preparation: screwdrivers, wrenches, rags, alcohol, watering cans, high-pressure water guns, cathode needle regulators, plastic boxes for soaking electric fields, etc.

1. Turn off the power supply to discharge the charge.

Although turn off the power switch of the body, there may still be electricity in the electrical box, so be sure to turn off the main switch of the potato chain power supply outside the device before carrying out equipment maintenance. Do not work with electricity to ensure the safety of cleaning staff.

2. Unscrew the bolt and pull out the electric field.

When the power supply has been disconnected, unscrew the bolts for fixing, open the maintenance door, and then pull both sides of the electric field by hand, and hold the end with your hand when the electric field is about to be withdrawn to prevent it from falling off suddenly and damaging the electric field.

3. Disassemble the accessories for easy cleaning.

Because the wet water of the insulator is very easy to cause leakage, it is necessary to remove the insulator, and separate the cathode pin and anode cylinder at the same time to facilitate further cleaning.

4. Electric field cleaning, soaking and rinsing.

Use a stainless steel or plastic cleaning tank container that is larger than the electric field. Shusun avoided soiling the floor during cleaning, so he wrapped the fume purifier and removed the wrapping bag in the container.

Soak with a caustic soda mixed solution with a weight ratio of 1:20 and hot water, according to the degree of oil stains, the length of soaking is also different, soak and then rinse with a high-pressure water gun with water, and place it in a clean place to dry.

5. Assembly inspection and correction.

After the electric field is dried, check whether there is any debris between the nest bees, keep it clean to prevent short circuit, and check whether there are any bumps on the outside of the anode cylinder. If so, slowly restore it with a round wooden stick.
