Dust filter purifier filter material cleaning is effectively used by the differential pressure sensor controlled pulse blowing mechanism, when the purifier is running for a period of time, its fine dust will adsorb on the surface of the filter material. This will reduce the permeability of the filter media.
When the differential pressure sensor detects the pressure difference signal output when the differential pressure exceeds a certain set value and the pulse generator receives the signal, the dust injection filter valve starts the pulse injection valve sequentially, clean compressed air is ejected from the valve port, and the ejected air flow is ejected. The filter cartridge is purged until the pressure difference is lower than another set value, and the fine dust adsorbed on the surface of the filter material is removed under the action of the air flow and falls into the dust collection hopper at the lower part of the chamber body. Pulse injection requires 0.4 to 0.6 MPa of clean compressed air, and must maintain continuous and constant supply of air during operation.
Dust filter performance characteristics:
The entire dust collection system has a very compact mechanism. During the design process, the reliability and environmental protection of the system must be fully considered. A deflector is designed at the inlet of the dust collector to reduce the dust gas to the filter cartridge. The impact of longer cartridge life.
The large cabinet structure design of the dust filter cartridge will reduce the resistance of the filter body to some extent. Reasonable ergonomic design concept facilitates inspection, repair and maintenance of equipment. The advanced control system design can always ensure that the equipment works under low power consumption conditions.
Filter cartridges commonly used automatic cleaning methods are high pressure gas pulse back blowing, mechanical vibration. The pulse backflush uses the parameters preset by the controller to send a signal to the solenoid valve to instantly open and close the diaphragm of the solenoid valve, so that the high pressure gas enters the injection pipe, and the dust on the surface of the filter cartridge is shaken off by the rapid expansion force of the gas. The general gas pressure We set about 6 kg force. Mechanical vibration cleaning is usually used for small single filter cartridge dust collectors. It uses the shaking force generated by the eccentric device of the dust collector to remove dust. This action needs to stop after operation.
