Air dust-cleaning device

Abstract

The invention discloses an improved air dust-cleaning device, which is characterized in that: air uniform-distribution plates as many as unit dust-cleaning chambers are arranged in an air inflow channel respectively; the air uniform-distribution plates are arranged in an inclined way, and the planes of the inclined air uniform-distribution plates face the air inlets of the unit dust-cleaning chambers; a flexible gasket is arranged between a chock plug of a pneumatic / or electric lift valve which is arranged in a unit air outflow channel and an air outlet of the unit air outflow channel; an electromagnetic valve / power switch of the pneumatic / or electric lift valve and a three-way electromagnetic valve of a blowing pipe of a filter bag blowing cleaning device are controlled by a programmable logic controller (PLC) respectively; and under the control of the PLC, filters of all the unit dust-cleaning chambers are cleaned by counter-spraying pulse blowing. The air dust-cleaning device has the characteristics of rational structure, good reverse-blowing and dust-cleaning effect of the filter bag, uniform dust filtration work of each filter bag, high whole dust-cleaning efficiency and the like.

Description

technical field [0001] The invention relates to an air dust removal device, in particular to an air dust removal device used for removing particles in the air in a clean room to meet technological requirements. Background technique [0002] The existing air dust removal equipment adopts back blowing on the side of the air outlet of the unit to clean the dust, and uses compressed air to blow the air out of the unit. Because the length of the air outlet of the unit is long, the pressured gas is directly blown into the air outlet of the unit. This will cause more air intake in the filter bag far from the blowing port, and less air intake in the filter bag near the blowing port, which will not achieve the effect of cleaning the filter bag evenly; while the existing dust removal equipment The plug head of the pneumatic / electric poppet valve and the air outlet of the air outlet of the unit are rigidly collided and kissed. After a long time, due to the number of collisions, the plu...

[0002] The existing air dust removal equipment adopts back blowing on the side of the air outlet of the unit to clean the dust, and uses compressed air to blow the air out of the unit. Because the length of the air outlet of the unit is long, the pressured gas is directly blown into the air outlet of the unit. This will cause more air intake in the filter bag far from the blowing port, and less air intake in the filter bag near the blowing port, which will not achieve the effect of cleaning the filter bag evenly; while the existing dust removal equipment The plug head of the pneumatic / electric poppet valve and the air outlet of the air outlet of the unit are rigidly collided and kissed. After a long time, due to the number of collisions, the plug head or the air outlet will be deformed, which will affect the sealing performance and make the cleaning The effect of the filter bag is not ideal; the air inlet of the existing dust removal equipment does not have an air volume uniform distribution plate, so that the unit located at the front end of the air inlet has a large air intake, while the unit located near the air inlet of the air inlet The indoor air intake is small, and the uneven air intake will affect the overall dust filtering effect of the existing dust removal equipment
