Large combination filter cartridge dust collectorIt's my companySingle machine pulse filter cartridge dust collectorA new generation of efficient products developed on the basis ofdust collectorYes, it isZhengzhou Jienengda Environmental Protection Equipment Co., LtdAdvanced technology developed to meet the requirements of high air volume flue gas purificationPulse dust collectorNot only does it haveSpray pulse dust collectorIt has the characteristics of strong dust cleaning ability, high dust removal efficiency, low emission concentration, stability and reliability, low energy consumption, and small footprint, making it particularly suitable for handling high air volume flue gas. Its various advantages have gradually been recognized by many users and widely welcomed. It has been adopted in fields such as steelmaking electric furnaces, abrasive smelting, calcium carbide furnaces, blast furnace gas purification, coal powder preparation and pneumatic conveying, asphalt concrete production, carbon black, building materials, refractory, chemical, aluminum electrolysis, aluminum zinc smelting, etc.
1Large combination filter cartridge dust collectorStructure and working principle:
Large combination filter cartridge dust collectorIt mainly consists of upper box, middle box, ash hopper, ash unloading system, injection system, and control system, and can adopt various intake chamber structures.
The dusty flue gas enters the ash hopper through the lower part of the middle box through the air inlet; Some larger dust particles fall directly into the ash hopper due to inertial collisions, natural settling, etc., while other dust particles rise with the airflow and enter various compartments. After being filtered by the filter cartridge, the dust particles are trapped on the outside of the filter cartridge. The purified gas enters the box through the filter cartridge of the dust collector, and is then discharged into the atmosphere through the lift valve and air outlet. The dust in the ash hopper is regularly discharged by the ash unloading system or continuously discharged bySpiral conveyorAnd the rigid impeller unloader is used for unloading. As the filtration process continues, the dust accumulation on the outside of the filter cartridge of the filter cartridge dust collector increases, leading to a gradual increase in the resistance of the filter cartridge dust collector itself. When the resistance reaches the preset value, the dust cleaning controller sends a signal to first close the lift valve of a filtering chamber to cut off the filtering airflow in that chamber, and then open the electromagnetic pulse valve. Compressed air flows from the air source through the air bag in sequencePulse ValveThe nozzle on the spray pipe sprays towards the filter cartridge in a very short time. Compressed air rapidly expands inside the box, causing high-frequency vibration and deformation of the filter cartridge. In addition, the effect of reverse airflow causes the dust cake attached to the outside of the filter cartridge to deform and fall off. After fully considering the settling time of dust (ensuring that the fallen dust can effectively fall into the ash hopper), the lift valve is opened, and the filter cartridge of this compartment returns to the filtering state, while the next compartment enters the cleaning state. This process continues until the last compartment is cleaned, forming one cycle.
Large combination filter cartridge dust collectorIt is composed of multiple independent rooms, and each room is cleaned in sequence without interfering with each other, achieving long-term continuous operation. The above dust cleaning process is automatically controlled by a dust cleaning controller at fixed time or pressure.
IILarge combination filter cartridge dust collectorcharacteristic
a. The filter cartridge uses polyester fiber as the filter material, adhering a layer of sub micron ultra-thin fibers to the general filter material. The arrangement of fibers on this adhesion layer is very tight, and the extremely small sieve holes can block most of the sub micron dust particles on the surface of the filter material;
b. The use of pleated filter media can increase the filtration area and make the structure of the dust collector more compact;
c. The filter cartridge is fixed to the lower partition with bolts and padded with rubber pads. Easy installation and maintenance;
d. Compared with dust collectors of the same volume, the filtration area is relatively large, the filtration wind speed is small, and the resistance is not high;
e. The dust collector adopts pulse blowing method for dust cleaning, which not only achieves thorough dust cleaning but also does not damage the filter cartridge, thus increasing the service life of the filter cartridge. The dust cleaning process is automatically controlled by a PLC controller and can be controlled by pressure difference or time. Multiple compartments are installed inside the dust collector to increase its usage area. Only one compartment is cleaned at a time, while the other compartments work normally. This achieves the cleaning effect without affecting the dust removal operation, allowing the dust collector to operate continuously for 24 hours;
f. Simple structure, high dust removal efficiency, and easy operation.
