36000m3 Ash Control Filter Cartridge Sawdust Removal System Wood Dust Collector

Introduction

The cartridge dust collector is operated under negative pressure. The dust-containing gas enters the tank through the air inlet; Under the action of the negative pressure in the folding filter cartridge, the gas enters the cylinder through the filter material outside the cylinder, and then enters the clean air chamber, and finally the clean gas is discharged from the air outlet. When the dust accumulates on the surface of the filter material, the resistance is getting larger and larger (can also be set by time), the pulse valve is opened, the compressed air is directly sprayed into the center of the filter cartridge, and the filter cartridge is sequentially pulsed to remove the dust, and the dust on the surface of the filter cartridge is purged.

Parameters

The working principle of cartridge filter

Cartridge filter is mainly composed of cabinet , filter cartridge and injection system, etc. When the dust gas into the dust collector, the sudden enlargement and air distribution plate will make the air flow in the part of coarse dust particles in under the action of gravity and inertia settling in ash hopper, fine granularity and density of small dust particles in dust filtering chamber.

By brown diffusion and sieve filter such as comprehensive effect, it makes the dust deposition on the surface of the filter material. The gas into after purification Air chamber by the exhaust pipe into the net. The resistance of cartridge filter material surface increase of the dust layer thickness.

Resistance to take when a specified value. At this time will be filtered air truncation first, and then open and electromagnetic pulse valve, the compressed air filter cartridge, make the filter cartridge expansion deformation produces vibration, and the reverse flow brush and attached to the filter bag looks on the surface of the powder. Ash hopper is sitting, stripped fall through the discharge valve discharge.

Structure Composition

Mainly consists of three parts: cartridge filter, cabinet and ash removal mechanism.

(1) Filter cartridge composed of outer layer. inner layer and the middle layer. Inner layer and outer layer are covered metal mesh (or hard plastic net). The middle layer is the fold type filter material. Cartridge filter characteristics is the filter material, put a layer of sub-micron ultra-thin fiber stick attached to the general filter material, The fibers on the adhesion layer are very close together, its clearance 0.12 - 0.6um. Due to the intensive folding and greatly increase the filter area, It has large area outstanding characteristic of filter cartridge.

(2) the cabinet is the shell of the dust collector, including the gas tank and ash hopper.Gas tank mainly provide the required cleaning space. It conducive to the reasonable distribution of flow field. The ash hopper is filtered to collect material.

(3) Ash removal mechanism mainly includes the blowpipe, pulse valve, air bags, etc. When the dust of filter cartridge surface reaches a certain thickness, It will be dedusted. The dust air througth filter cartridge, and then discharged. When the filter resistance to the differential value or time setting, It will controlled by differential pressure gauge or gain control instrument between the corresponding electromagnetic valve. The pulse valve in the closed state, compressed air blowing the filter cartridge to pulse ash removal.
