Dust removal equipment, the equipment that separates dust from the flue gas, is also called dust collector or dust removal equipment.
LONGFA™ ▍Bag type dust collector Lower cost for high temperature dust removal with the same efficiency Bag filter is a kind of dry dust filter device. After the filter media is used for a period of time, due to the effect of sieving, collision, retention, diffusion and static electricity, a layer of dust accumulates on the surface of the filter bag, this layer of dust is called the primary layer, in the process of movement thereafter, the primary layer becomes the main filter layer of the filter media, relying on the role of the primary layer, the filter media with larger mesh can also obtain a higher filtration efficiency. With the accumulation of dust on the surface of the filter media, the efficiency and resistance of the dust collector increase accordingly. When the pressure difference between the two sides of the filter media is large, some fine dust particles that have been attached to the filter media will be squeezed over, so that the efficiency of the dust collector decreases. In addition, the high resistance of the dust collector will make the air volume of the dust removal system drop significantly. Therefore, after the resistance of the dust collector reaches a certain value, it should be cleared in time. When cleaning ash, the initial layer should not be destroyed, so that the efficiency will not drop. | ||

LONGFA™ ▍Cartridge type dust collector Continuous filtration Stable operation The filtration mechanism of the cartridge dust collector is the result of a comprehensive effect, such as gravity, inertia force, collision, electrostatic adsorption, sieving and filtering action. When the soot and dust containing gas enters the dust collector through the air inlet, the larger dust particles settle directly due to the increase in cross-sectional area and decrease in wind speed; smaller soot and dust particles are stopped by the filter cartridge on the surface of the filter cartridge. The purified gas through the filter cartridge is discharged by the induced draft fan through the air outlet. When the resistance of the equipment reaches a certain limit, the soot and dust accumulated on the surface of the filter cartridge need to be removed in time; under the action of pulse compressed gas, the back-blowing of the filter cartridge will remove the soot and dust attached to the surface of the cartridge, so that the cartridge can be regenerated, and the cycle will be repeated to achieve continuous filtration to ensure the continuous and stable operation of the equipment. |  | |

LONGFA™ ▍Dust filter cartridge Industrial filters for a wide range of industries A cartridge, as the name implies, is a cartridge element used for filtration. Cartridges are generally divided into those used to filter liquid media and those used to filter gas media. Cartridges are surface filtration elements that use tiny air permeable tissues formed on the surface of the filter material to block out airborne particulate matter. The design air speed of the filter cartridge is a key parameter, which is related to the operation effect of the whole dust collector. In general, we suggest that the design air speed of the filter paper containing wood pulp fiber should not exceed 0.6m/min, and the recommended design air speed of polyester non-woven fabric is 1m/min, of course, we also need to consider the specific characteristics of the filtered dust. | ||
