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.
Cartridge filter is the filter who use filter cartridge as filter element. On the basis application of pulse bag filter, it is the new product for the air dust and industrial powder (smoke) dust removal. With its high air volume (not less than 99.5%, The low pressure 0.2 - 0.6 mpa), If better operation parameters low resistance loss (800 - 1000 Pa) will be favored by users. The cartridge filter has the advanced technology, compact structure, emission standard, covers an area of less, low investment and low operating cost marked characteristics.
Cartridge filter pulse dust collector is suitable for the blast furnace blower inlet dust, oxygen generator, air compressor inlet dust removal, control room gas dust removal, master control room air intake inlet dust, clean workshop, public building air-conditioning inlet dust removal and flue gas dust removal of low concentration. With the continuous development of material and dedusting technology, the cartridge filter are enlarge the application domain gradually. For now, it has been widely used in building material, metallurgy, electric power, food, chemical and other industries, etc. It has the part replace of bag filter and ESP dust collector, etc.
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.
