Cooking fume is very harmful to human body. Cooks will produce harmful gases such as cooking fume, carbon monoxide, carbon dioxide and nitrogen oxides, and long-term inhalation of these harmful substances will easily lead to diseases such as cancer. The treatment of cooking fume is very important, which not only affects the health of chefs but also harms the health of residents living around. I hope that the following principles and cleaning methods of catering oil fume purifier can help you prevent oil fume.

working principle of catering oil fume purifier

the oil fume is sucked into the electrostatic oil fume purifier by the fan, and some of the larger oil droplets and oil pollution particles are trapped on the uniform flow plate due to mechanical collision and retention. When the airflow enters the high-voltage electrostatic field, under the action of the high-voltage electric field, the oil fume gas is ionized, the oil mist is charged, and most of it can be degraded and carbonized; A small number of tiny oil particles move to the positive and negative plates of the electric field under the action of electric field force and airflow of the adsorption electric field, and are collected on the polar plate and flow down to the oil collection tray under the action of their own gravity, and are discharged through the oil discharge channel, and the remaining micron-sized oil mist is reduced to carbon dioxide and water by the electric field, and finally clean air is discharged; At the same time, under the action of the high voltage generator, the air in the electric field produces ozone, which removes most of the odor in the flue gas.

installation requirements of smoke purifier: (1) it is recommended to install the kitchen fume purifier in front of the fan, which can make the purification effect better and prolong the service life of the fan.

(2) when the air inlet and outlet are connected to the pipeline by flanges, pay attention to the sealing of the pipeline connection port and the equipment connection port. (3) The fume purifier can be installed indoors or outdoors. ? (4) In strict accordance with the use requirements, pay attention to the reliable grounding of the box.

cleaning method of cooking fume purifier

1. cleaning cycle

the purifier needs to be cleaned after two to three months of use, and the cleaning cycle should be shortened when there is a lot of cooking fume in the kitchen to ensure the treatment effect of the purifier.

2. Cleaning method

1. Cleaning of pretreatment net:

(1)? Cut off the power supply and open the access door.

(2) Pull out the pretreatment net.

(3) soak it in the cleaning tank for ten minutes, gently clean the online oil stain, and rinse it thoroughly with clear water.

(4) naturally air dry that cleaned pretreatment net.

(5) Put the dried pretreatment net back to the oil fume purifier in its original position.

2. Electric field cleaning:

(1) Cut off the power supply, open the access door and take out the electric field.

(2) Put a cleaning sheet (plastic sheet) in the middle of the electrode plate and move it from top to bottom next to the electrode plate. It is only necessary to clean most of the oil on the electrode plate. If it is not cleaned once, it can be cleaned many times.

(3) Clean up the scraped oil and wash it with clean water.

(4) the cleaned electric field is naturally dried (if there is still a small amount of oil, it will not affect the purification effect of the product).

(5) Put the dry electric field back to the purifier according to its original position, and then close the access door to work again.

Precautions for oil fume purifier

1. Air leakage prevention measures should be taken at the connection of each air duct. In order to ensure the infectious efficacy of the equipment.

2. The variable diameter air duct adjacent to the air inlet and outlet of the equipment should be as smooth as possible to ensure the infectious effectiveness of the equipment. Straight pipes with a length more than 4 times larger than the pipe diameter must be assembled and connected by smooth pipes.

3. Therefore, soft connection must be adopted when the air duct of the equipment light fan is connected. The equipment will not work normally when it is vibrated during operation.

4. in order to ensure the infection result, the air volume of individual fans should be larger than the intended air volume of the equipment. The equipment must work under the planned air volume, and the user can control the fan with frequency converter or install an air regulating valve device at the outlet of the fan.

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

6. The equipment should work under negative wind pressure to ensure the infectious effectiveness 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 air volume allocated to each device is close to the proportion of air volume he intends to handle.

8. A rain-proof, sun-shading awning should be installed. So as to avoid affecting the normal operation life of the equipment and increasing unnecessary maintenance cost. Three meals are inseparable from people's lives every day, and the fumes and harmful gases produced when making "three meals" are inevitable. The existence of the fume purifier solves this problem well. Although it can't completely eliminate the fumes and harmful substances, it can reduce the amount of human intake. Attention should also be paid to the cleaning of the oil fume purifier in daily use, so as to prolong the service life of the purifier. Although there will be more oil pollution when cleaning the lampblack purifier, the accumulation of more oil pollution can be avoided if the cleaning frequency is higher.

that's all about the principle of cooking fume purifier. I hope it can help you! ?
