The dust removal equipment adopts the internationally advanced off-line three-case (filtration, dust removal and suspension) dust removal method, which avoids the "re-adsorption" phenomenon during dust removal and makes dust removal complete and reliable. It is planned to have a pre-dust collection arrangement, which not only overcomes the shortcomings of the dust directly scouring the filter cartridge, but also can greatly improve the dust concentration at the entrance of the dust removal equipment. For the key components (such as pulse valve) that affect the main performance, high-quality wear-resistant components are selected, and the service life of the vulnerable diaphragm exceeds 1 million times. Select and place the skill of blowing and cleaning ash. A pulse valve can blow one column together (the number of filter cartridges in each column is up to 12), which can greatly reduce the number of pulse valves. Pulse valve three ash arrangement selection of PLC automatic control, and both punctual or manual two control methods optional. According to the needs of the equipment space, you can choose any combination of filter cartridges with different columns and rows. The three-dimensional space occupied by the unit filter area is small, which can save a lot of space cost for the user and indirectly reduce the user's one-time cost. The service life of the filter cartridge dust removal equipment is long, and the service life of the filter cartridge can reach 2 years, which greatly reduces the number of times the filter element of the dust removal equipment is replaced (the traditional bag dust removal equipment is replaced every 6 months), the protection is simple, and the protection cost of the user in the application process is greatly reduced.

Operation process of filter cartridge dust removal equipment:

After the dust-containing gas enters the dust hopper of the dust removal equipment, due to the sudden expansion of the air flow section, some coarse dust particles in the air flow settle down under the action of gravity and inertial force. After the dust particles with fine particle size and small density enter the filter chamber, the dust is deposited on the surface of the filter material through the generalization effects such as Brown laxity and sieve filtration, and the purified gas enters the net air cavity of the upper box through the filter cartridge and is collected to be discharged. The resistance of the filter cartridge dust removal equipment increases with the increase of the thickness of the dust layer on the surface of the filter material. When the resistance reaches a specified value, the dust shall be removed. In order to ensure the normal operation of the system, the upper limit of the resistance of dust removal equipment should be maintained within the scale of 1400~1600Pa. When the scale of this constraint is exceeded, the PLC pulse automatic controller should announce instructions through fixed resistance or punctuality to carry out dust removal in three situations. Finally, the dust collected in the ash hopper is discharged continuously through the ash discharge valve.
