Process principle description

Filter process

After the air passes through the filter element, due to the combined effects of gravity, inertial diffusion, static electricity, and contact retention, dust settles and accumulates on the filter element, and the clean air is sent to the air through the venturi tube. Export.

Self-cleaning process

The dust on the air filter element is automatically controlled by the microcomputer through timing or constant pressure difference, and the filter element is blown back in turn, and the sediment particles are blown into the atmosphere. Only one group (six) of filter elements are used each time during the self-cleaning process. 30 seconds, other filter elements are still in normal filtration working state, ZKG runs as usual

Technical features

(ZKG-800) Pneumatic self-cleaning air filter control system adopts full digital control, can run for a long time, has the characteristics of stable work and high control precision, and can modify the program according to customer requirements. Production status. All control loops are completed by programmable controllers. The command signal output by the computer makes the solenoid valve open and close, so as to open and close the self-cleaning gas source to achieve the purpose of self-cleaning of the filter.
