Background
In the cement production process, in order to make the dust emission reach the standard, an electric dust collector, a bag-type dust collector and an electric bag mixing dust collector are generally used for processing.
The bag-type dust collector is divided into a plurality of air chambers, the air chambers are sequentially and circularly vibrated and blown according to a designed flow, and an air compressor provides a certain pressure air source as a lift valve and vibration blowing power. When one air chamber is vibrated, blown and dedusted, the control electromagnetic valve of the air chamber poppet valve is closed to cut off the air source, so that the poppet valve body is in a closed state (i.e. the rest air chamber poppet valves are in an open state), the air outlet is closed, the quick exhaust valve is opened, and the high-pressure air is blown and dedusted. After the operation is finished, the quick discharge valve is closed, the solenoid valve of the pneumatic lift valve is opened, the lift valve is in an open state, and the next air chamber is switched to work.
