What is the principle of industrial fume purifier treatment?

The principle of industrial fume purifier treatment: the fume gas discharged from the production workshop enters the industrial centralized fume purifier, first carries out coarse filtration into the oil fume separation area, and then enters the high-pressure ionization area and low-pressure dust collection area to purify most of the oil droplets and pollutants below 3 microns, with a removal efficiency of more than 95%, and can be configured to automatically clean the oil mist separation area system process, which completely achieves no oil smoke and meets the EIA standard after multi-stage treatment.

Oil smoke gas - purification equipment - oil smoke separation area - high pressure ionization area and low pressure dust collection area - high pressure ionization area and low pressure dust collection area.

How different kinds of oil fume purifiers work:

1.Catalyst combustion.

The principle of combustion purification method is to use the heat generated by high-temperature combustion to carry out oxidation reaction, and convert the pollutants in the oil smoke exhaust gas into CO2 and H2O and other substances, so as to achieve the purpose of purification. In the combustion process, the oil smoke exhaust gas is passed through the self-purifying catalyst, and the catalytic reaction of the catalyst is conducive to the conversion of pollutants. Generally, ceramic or metal honeycomb is used as a carrier for oxidation catalysis.

This type of fume purification equipment is only suitable for occasions with very low fume concentration, such as eating raw food or making semi-finished products.

2.Activated carbon adsorption method.

Use granular activated carbon or activated carbon fiber felt to adsorb pollutant particles in oil smoke. The characteristics of this equipment are similar to those of filtration and purification equipment, but the effect of removing oil smoke odor molecules is better.

3.Electrostatic treatment.

Under the action of the electric field and the applied high voltage, electrons emitted from or near the wire of the negative electrode rapidly move towards the positive electrode, colliding with the gas molecules and ionizing. When the oil smoke exhaust gas passes through this high-voltage electric field, the oil smoke particles are charged due to the collision and capture of gas ions in a very short time, and the electric field force moves to the positive electrode dust collection plate, so as to achieve the separation effect. This kind of equipment has less investment, small footprint, no secondary pollution, and low operating costs.

Due to the ease of capturing small particle size dust, the purification efficiency is high, up to 85 to 95%. The difference between its purification mechanism and the gas method is that the separation force is an electrostatic force, which acts directly on the particles, rather than on the gas flow, so it has the characteristics of low energy consumption and low resistance.

The working principle of the oil fume purifier: the oil fume exhaust gas first passes through a certain number of metal grids, and the large particle pollutants are intercepted; Then, after passing through the filter media such as fiber pads, the particulate matter is removed due to diffusion and retention.

The filter material usually selected is a polymer composite material with high oil absorption performance. This kind of equipment has low investment, low operating cost, no secondary pollution, and convenient maintenance management; However, it has the disadvantages of high resistance, large land occupation, and frequent replacement of filter media.

Due to the great resistance of the filter material, such as the pressure drop of the purifier of the glass fiber filter material can reach 1500pa, and the filter material needs to be replaced frequently, the application of filter purification equipment is limited.

The 220V power supply converts the output of 6500V and 13000V medium and high voltage through the high-voltage packet. The high-voltage power supply is delivered to the discharge electrode, and the medium-voltage power supply is delivered to the collecting electrostatic field. The fume exhaust gas is ionized through the high-voltage discharge electrode, so that the fume exhaust gas is charged, and the fume exhaust gas enters the collected electrostatic field and is absorbed by the electric field to the electrostatic plate electrode, so as to intercept the oil smoke particles and achieve the purpose of purification.

The oil fume purifier is equipped with a unique oil contact and suction unit, the oil fume passes through the purifier, and under the action of the high-voltage plasma electric field, the tiny oil particles and gas are ionized and charged, and the charged tiny ions (oil particles) are collected by the adsorption unit and flow into and deposit into the oil storage tank of the purifier, and the purified gas is discharged after being pressurized by the fan. After the kitchen fume is treated by the electrostatic fume purifier, the fume purification rate can reach more than 90%.

Fume purifier process features:

1. High purification efficiency and stable operation.

2. Compact structure, novelty, small size, light weight, easy installation and use 3, low operating cost and low power consumption.

4. The wind resistance of the equipment is small.

The electrostatic oil fume purifier uses the electrons emitted by the cathode in the high-voltage electric field, as well as the negative ions generated by the electrons colliding with air molecules to capture the oil smoke, black smoke, oil mist and other particles, so that the particles are charged, and then use the adsorption of the electric field to make the charged particles adsorbed by the anode, so as to achieve the purpose of removing and purifying the oil smoke.

Generally speaking, low-altitude electrostatic fume purifiers** are more efficient and more expensive than high-altitude electrostatic fume purifiers, but low-altitude oil fume purifiers meet local emission standards in many areas.

The principle of Shuangni fume purifier mainly uses an ionization separation structure similar to the superposition of the plate, the plate electric field is divided into the ionization zone and the adsorption area, the device that separates each other, the fume exhaust gas first passes through the ionization zone, and the ionization zone emits a voltage of 12kV for ionization, and the fume becomes a positively charged particle, thus entering the adsorption zone, and the adsorption zone emits a voltage of 6kv, and the positively charged fume particles are adsorbed in the adsorption zone due to the action of the electric field force to achieve the purification effect.

Catering kitchen fume purifiers are mainly used in the catering industry, such as hotels, canteens, food processing factories and other kitchen fume purification treatment. The oil smoke air passes through a special S-shaped baffle to balance the inertial collision separation, remove the coarse oil smoke particles, and enter the high-voltage electrostatic field, so that a large number of oil mist particles are adsorbed on the dust collection board, and then through the modular metal wire mesh and activated carbon filtration and adsorption combination, the last remaining substances and peculiar smells are removed, and the purified clean air is discharged.

The range hood is mainly used in the home or commercial kitchen, through the suction fan to suck a large amount of exhaust gas and fume into the exhaust fan, and then through the air duct to the outdoors, to purify the air and protect people's health. The main function of the range hood is to absorb and collect the fumes, steam, odors and other gases generated around the stove through the exhaust function of the fan, so that Dana can purify the air. In the design of modern range hoods, the functions of adsorption, separation, purification and so on are also added, so that the effect of range hoods is better.

When operating cooking utensils, a large number of harmful substances such as oil smoke and steam will be produced, which can easily endanger people's health, and if they are not discharged in time, they will have harmful effects on health. However, through the normal use of the range hood, it can remove harmful substances such as exhaust gases and oil fumes, freshen the air, and protect people's health.

1. Safe and fireproof, stable operation.

As a place with a high incidence of fires, it is very important to prevent fire and disaster hazards on a daily basis, which requires the fume purifier to be safe and stable during operation to prevent open flames caused by the phenomenon of ignition. Therefore, the wide volt is to choose a fume purifier with leakage protection and isolation of open flames to effectively prevent the occurrence of fire.

2. The purification effect is good, and the fume is treated.

The fume purifier is a kind of environmental protection equipment specializing in kitchen fumes, and most of them are used in kitchens with relatively large fumes in the catering industry. In the daily fume emission, the relevant departments have issued a set of clear standards, so the installation and use of fume purifiers need to be qualified. The good effect of the oil fume purifier indicates that it can effectively deal with the oil fume in terms of purification efficiency, and the inspection can be calmly dealt with.

2. After-sales guarantee, peace of mind.

Because of its purification principle, the oil fume purifier needs to be maintained in a timely and effective manner, so that the oil fume purifier can run safely and stably. Therefore, the manufacturer's after-sales guarantee is also equally important, and when the equipment fails due to non-human factors, it can provide effective protection to ensure the stable operation of the equipment and the user's peace of mind.

1. Match the kitchen stove and air volume. The number of kitchen stoves is strictly matched with the air volume of the equipment, so as to give full play to the best purification effect and make the fume treatment efficiency meet the emission standard. If the stove is added to the kitchen, it needs to be replaced and rematched to increase the air volume, and the fan power also needs to be increased in response to ensure the stable efficiency of the fume purifier.

2. Clean the electric field of the equipment in time. The purification efficiency of the oil fume purifier is greatly reduced, and it is known that part of the reason is that the internal electric field has not been cleaned for a long time, resulting in excessive accumulation of oil fumes in the internal electric field, which is attached to the electric field electric plate, and ultimately leads to poor ionization effect of the electric field, and the purification effect will become worse. Therefore, timely cleaning of equipment is an important step to maintain its purification efficiency.

3. Regularly inspect and maintain equipment. The whole set of fume purification system is composed of fans, purifiers, pipes and other components, so the coordination of each component is an important guarantee to maintain the purification efficiency.

The oil fume purifier is mainly used for the purification and treatment of low-altitude emission oil fume in the kitchen.

The oil fume purifier 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.

Oil fume purifier, as the name suggests, refers to a device that treats kitchen fume exhaust gas to improve the kitchen environment. So how does a fume purifier work? What do I need to pay attention to when using it? See below.

First, the working principle of the oil fume purifier.

Oil smoke through the purifier, under the action of high-voltage plasma electric field, the tiny oil particles and gas are ionized charged, the charged tiny ions (oil particles) are collected by the adsorption unit, and flow into and deposit into the oil storage tank of the purifier, the harmful gases in the smoke and dust are sterilized by the ozone generated in the electric field, and the odor is removed, the harmful gases are removed, the removal rate of oil smoke is detected by the monitoring department identified by the State Environmental Protection Administration, the removal rate reaches more than 95%, and the clean air is discharged through the air outlet and discharged up to the standard.

2. Precautions for the use of oil fume purifiers.

1. The connection of each air duct shall take anti-leakage measures. To ensure the contagious efficacy of the device.

2. The reducer air duct adjacent to the air inlet and outlet of the equipment should be as smooth as possible to ensure the infectious effect of the equipment. Straight pipes that are more than 4 times longer than the diameter of the pipe must be assembled and connected with smooth pipes.

3. Therefore, the soft connection must be used when the air duct connection of the light fan of the equipment is used. If the device is vibrated while it is running, it will not be able to perform properly.

4. In order to ensure the infection result, the air volume of the individual fan is supposed to be greater than the intended air volume of the equipment. The equipment must work under the intended air volume, and the user can use the inverter to control the fan or install a regulating valve device at the air outlet of the fan.

5. To reduce the additional resistance of the fan. It is best to keep a 1-2 meter straight pipe section at the inlet of the fan.

6. The equipment should work in a negative wind pressure state to ensure the infectious effect of the equipment. That is, the fan must be located in front of the equipment.

7. When the air is exhausted by a unified exhaust fan, when multiple devices are used in parallel. It is also necessary to ensure that the proportion of the air volume allocated to each device is close to the proportion of the air volume that he intends to handle only for the elderly.

8. Awnings for rainproof and sunshade should be installed for outdoor assembly. It can affect the normal handling life of the equipment and increase the unnecessary maintenance cost.
