Product Principle

Self-cleaning air filter is mainly used for intake air purification, remove the dust particles, in addition, some production process of the exhaust contains small pollutants in this kind of purification, belongs to the exhaust purification, because of its high purification requirements, also need to use self-cleaning air filter. Self-cleaning air filter refers to an air filter device, which is generally used for dust prevention in clean workshops, clean workshops, laboratories and clean rooms, or for electronic mechanical communication equipment. Guohai self-cleaning air filter is composed of filter cylinder, clean air chamber, pulse self-cleaning compressed air distribution pipe, air intake protection net, skirt plate, steel frame, electric control instrument, PLC and so on. Under the suction negative pressure of the compressor, the self-cleaning air filter inhales the ambient air, due to the combined effect of gravity, static electricity, contact resistance, inertial diffusion, etc., the dust in the air is deposited on the outer surface of the filter cartridge filter material, and the clean air is confluent in the clean air chamber and enters the compressor through the outlet pipe. When the PLC issues a self-cleaning command, the solenoid valve will instantly open for about 0.1 to 0.2 seconds, send a pulse air flow, and blow away the dust on the outer surface of the filter cylinder by spraying and backblowing. This backblowing self-cleaning process is intermittent, with only three to four cartridges in a backblowing self-cleaning state at a time, and the rest of the more cartridges continue to work. Therefore, the self-cleaning air filter has an online self-cleaning function to ensure the continuous work of the air compressor. The cleaning mode of Guohai self-cleaning air filter has three kinds: pressure difference, timing and manual. Self-cleaning mode Select Settings on the controller.

Self-cleaning air filter instructions:

1, the requirements for compressed air: pressure: 0.4 ~ 0.6Mpa temperature: ≤40℃ Compressed air should also be clean, dry, oil-free (purify compressed air or nitrogen);

2, clean the filter air room before starting, clean the air room, and then use wet flour to stain;

3. Regularly clean the intake air protection net. After the self-cleaning air filter filter is used for a period of time, the intake air protection net will be stained with dust and debris, resulting in an increase in filtration resistance greater than 2000Pa, the intake air protection net should be cleaned. The application of water cleaning, the use of rubber hose to wash the intake air protection net, should avoid water splashing on the filter cartridge;

4, the cleaning of the filter cartridge, in order to maintain and maintain the filter, the filter adopts the compressed air pulse back blowing method, so that the filter cartridge cleaning, each time a solenoid valve action, 3 or 4 filter cartridges at the same time back blowing. Self-cleaning methods have timing, differential pressure and manual three ways to choose.

5, in order to prevent the dust blown down by the filter cartridge from being adsorbed on the adjacent filter cartridge, the following three measures are adopted:

① Increase the distance between filter cartridges;

② A partition board is arranged between each backblown filter cartridge group;

③ Low filtration flow rate of the filter cartridge.

6. Replacement of filter cartridge

In order to ensure the reliable work of the filter and effectively protect the air compressor, the filter cartridge should be replaced for about 1 year.

7. Special notes:

① It is strictly prohibited to turn on the outer packaging of the high efficiency filter cartridge (nylon bag) before it is opened, otherwise the consequences caused by the user's own responsibility;

(2) Clean the clean air room, and then use wet flour to stain, respectively by the operator and inspectors to confirm that the clean air room without any dust and debris before driving;

③ The design pressure difference of the air filter structure is -3000pa. If the pressure difference is exceeded, the equipment will be damaged. When the pressure difference is close to -2000pa, the filter cartridge should be treated or replaced in time.

(4) The compressed air should be clean, dry and oil-free, otherwise the solenoid valve can not operate normally and the service life of the high efficiency filter cartridge will be greatly shortened;

⑤ After the controller is powered on, please close the air switch in the controller.

Features of self-cleaning air filter:

1, the core component of the self-cleaning air filter cartridge, the selection of imported filter material;

2. The self-cleaning air filter is designed with a primary coarse filter protection net for intake air to protect the filter cartridge;

3, self-cleaning air filter is computer-controlled mechatronics products, as long as the customer is equipped with pipes, power on, self-cleaning air filter can work normally;

4, self-cleaning air filter filtration efficiency (weight method) up to 99.99%, filtration accuracy (2μm) is 99.99%;

5, self-cleaning air filter resistance loss is small;

6. If the resistance loss is abnormally increased during operation, the self-cleaning air filter will send an alarm signal;

7, self-cleaning air filter self-consumption of compressed air is very small, only 0.1 ~ 0.4m /min;

8, self-cleaning air filter power consumption is very small, the power capacity is only 100 ~ 500W;

9, small footprint, large self-cleaning air filter can use multi-layer structure;

10. The self-cleaning air filter is a building block assembly structure, which can meet the special requirements of customers;

11, the self-cleaning air filter has a simple structure, light weight of the equipment, and the quality is only 1/3 to 1/2 of the quality of the same capacity cloth bag air filter.
