5500m3/min self-cleaning air filter

5500m3/min self-cleaning air filter

  • SUMMARY: After the self-cleaning air filter inhales the air containing dust, it will cause wear and tear of the equipment, and the inhaled dust will scale on the surface of the fan blade, resulting in the dynamic balance of the rotor in the equipment....

Product introductions:

5500m3/min self-cleaning air filter The air inlet filter is equipped with a first-level protective steel mesh, a second-level fiber filter cotton, and a three-level high-efficiency filter cartridge. Most of the coarse and medium dust particles in the air flow of the self-cleaning air filter precipitate to the dust collector drawer under the action of gravity and inertia, the fine dust is attached to the surface of the filter cartridge, and the clean air passes through the clean room in parallel, and then enters the power equipment

The dust containing waste gas enters the dust collector

After the tuyere, due to the sudden expansion of air flow section and the action of air flow distribution plate, the wind speed drops sharply, and some coarse particles in the air flow collide with each other under the action of wind power and inertia force

Naturally settling to collect ash at the bottom

Fight; The dust particles with fine particle size and small density are deposited on the outer surface of the filter cartridge and intercepted through the combined effect of diffusion and screening, and the clean gas penetrates the inner wall of the filter material and enters the clean room and is extracted by the exhaust pipe through the fan. The resistance of the filter cartridge will increase with the increase of the thickness of the dust accumulation layer on the surface of the filter material. The injection control mode can be divided into pressure difference control, time sequence control and manual control. For example, differential pressure control: when the resistance reaches a certain set value, the digital differential pressure instrument stimulates the signal, the pulse controller or the PLC control program receives the feedback signal, automatically judges the data, orders the chain execution action, and automatically carries out the opening and closing valve spray cleaning.

Performance characteristics:

1, self-cleaning air filter process air through the filter cylinder, due to gravity, inertial diffusion, static electricity, contact retention and other comprehensive effects, dust settlement, accumulation on the filter element, clean air through the ventura tube and then to the outlet sent out.

2, the dust on the air filter element of the self-cleaning process, with a timing or fixed differential pressure, is automatically controlled by a microcomputer, in turn, the filter cylinder is blown back, and the particulate dust of the fallout is blown into the atmosphere, each time only one group (five) of the filter cylinder is in the self-cleaning process, the interval is 60 seconds, the other filter is still in the normal filter working state, ZKG runs as usual.

3, the control system of the self-cleaning air filter, using full digital control, it can run for a long time, with stable work, high control accuracy, and can modify the program according to the production situation. All the control loop is completed by a programmable controller, and the command signal output by the computer makes the solenoid valve open and close, so as to open and close the self-cleaning air source to achieve the purpose of self-cleaning the filter
