Filter Cartridges

As an inherent part of the TODC-M immersed flow dust collector, the cartridge and the dust collector are cleverly combined to greatly enhance their respective functions, giving the unit unparalleled performance and extending the service life of the cartridge. The combination of the cartridge and the dust collector greatly enhances their respective functions, giving the unit unparalleled performance and extending the life of the cartridge. This ingenious concept and design also This ingenious concept and design also optimizes the maintenance and servicing of the cartridges, giving the TODC-M a unique advantage in the industry. Due to the long service life of the cartridges and the Due to the long service life of the cartridges and their excellent dust collection and cleaning capacity, cartridge replacement is rarely required.

The dust collector uses a high efficiency filter cartridge as the filter element, which differs from conventional filter media in that it is coated with a Teflon film. Traditional filter materials (such as cotton, cotton satin, paper and other traditional cellulose, etc.) have a fiber gap of 5 to 60 um. When the soot passes through, some of the dust particles will enter the filter material and block the filter element; when the blockage gradually worsens and effective dust cleaning is not possible, the air resistance of the filter element will rise and the air flow rate will drop. If there is no automatic dust cleaning, the filtration effect will drop rapidly, but the surface of the filter material used in this series of dust collectors is equipped with a layer of PTFE film, whose tiny screen pores can block most of the submicron dust particles; submicron dust particles gather on the surface of the filter material and form a permeable dust barrier cake, most of the dust particles are blocked on the outer surface of the filter material and cannot enter the inside of the filter material, which can be removed effectively in time under the blowing of compressed air. The filter media has a high filtration efficiency, at least 3 to 5 times higher than the traditional filter media, and the filtration efficiency for ≥0.1μm soot is ≥99.99%; and the service life is more than 2 times higher than the traditional filter media.

The cartridge adopts PTFE laminated filter material, which is a new type of fume and dust capturing filter element, and its filtration effect can be very impressive even in a particularly harsh environment. For non-bonded dusts, PTFE laminated filter elements can achieve high filtration efficiency. Even if Even at ambient temperatures below the dew point, the filter element maintains a constant filtration capacity. The high mechanical stability of the material ensures a long filter element service life of the filter elements. The design of the filters ensures that they are compatible with existing filtration systems. advantages of rigid body filtration. The small size and large filter area of the robust rigid filter body allow for high operating pressures and a very long service life.

Self-cleaning principle of the filter cartridge

Cleaning of the dust collector filter material is achieved by means of a pulse blowing mechanism controlled by a differential pressure sensor: after a period of operation of the dust collector, fine soot is adsorbed in the filter material. After a certain period of operation, fine soot is adsorbed on the surface of the filter material, making the filter material less breathable. The two detection heads of the differential pressure sensor are installed on the raw air side and on the net air side. one on the raw gas side and one on the net gas side. When the differential pressure sensor detects the differential pressure exceeds a certain set value, the differential pressure signal is output and the pulse generator receives the signal. After the pulse generator receives the signal, the pulse blowing valve is activated sequentially, clean compressed air is ejected from the valve port, and the airflow is directed to the filter cartridge for blowing until the differential pressure is lower than another set value. The dust adsorbed on the surface of the filter material is removed under the action of airflow and falls into the dust collection hopper in the lower part of the chamber.
