The filter cartridge filter cartridge is composed of a filter cartridge or a pulse jet filter. The filter cartridge dust collector according to the installation method, can be divided into oblique insertion type, side mounted type, lifting type, jacket type. Cartridge filter cartridge according to the material, can be divided into long fiber polyester cartridge filter, fiber cartridge filter, anti-static cartridge filter, flame retardant cartridge filter, film cartridge filter, nano filter cartridge dust collector.
Classification:
The filter cartridge dust collector according to the installation method, can be divided into oblique insertion type, side mounted type, lifting type, jacket type.
Cartridge filter cartridge according to the material, can be divided into long fiber polyester cartridge filter, fiber cartridge filter, anti-static cartridge filter, flame retardant cartridge filter, film cartridge filter, nano filter cartridge dust collector.
Structure:
The structure of the cartridge filter is composed of an air inlet pipe, an exhaust pipe, a box, an ash bucket, ash cleaning device, guiding device, the airflow distribution board, shunt filter cylinder and an electric control device, similar air box pulse bag dust removing structure.
Filter cartridge in the dust collector is very important, not only can be arranged vertically in the box flower board, also can tilt the arrangement in the flower board, from the cleaning effect, vertical layout is reasonable. The lower part of the flower board is a filter chamber, and the upper part is a gas chamber impulse chamber. Airflow distribution board is installed at the entrance of the dust collector.
Working principle：
The dust laden gas into the precipitator hopper, the air section suddenly expand and the air distribution plate, a part of the coarse particles in the air and under the force of inertia settlement in the ash hopper; fine granularity, density of small dust particles into the dust filtering chamber, through the Brown diffusion and the sieve combination effect, the dust deposition on the filter surface, the purified gas enters a clean air chamber from the exhaust pipe through the exhaust fan.
The resistance of the filter cartridge filter 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, it can be cleaned. The PLC program control on-off pulse valve, a first compartment poppet valve closed, air filter will be truncated, then the electromagnetic pulse valve open, compressed air and a short time in the case on the rapid expansion of the influx of the cartridge, the cartridge expansion deformation vibration, and erosion in the reverse gas under the action of attachment of dust in the outer surface of the bag on the stripped into ash hopper in. After the cleaning is completed, the electromagnetic pulse valve is closed, the valve is opened, and the chamber is recovered and filtered. Each room in turn is carried out in order to start from the first chamber to the next one. Off the dust in the hopper through the ash unloading valve into the discharge.
Regularly on the cartridge replacing and cleaning must be in the process, to ensure that the filtering effect and precision, because the dust in the filtering process in addition to being as part of barrier deposition on the surface of the filter material, increasing the resistance, so the correct replacement time is generally three to five months
