    The working mechanism of HMCN long bag pulsed precipitator is introduced

    RELEASE DATE:2019-08-27 PUBLISHER:BACKUPDATA

    HMCN type pulsed bag dust collector is a new type pulsed bag dust collector which has been successfully developed based on the advanced dust removal technology in China.Widely used in electric power, building materials, metallurgy, coking, boiler, chemical and other industries of flue gas treatment, dust removal efficiency reached more than .

    Working mechanism

    The dust and smoke gas is filtered through the filter material, and the dust particles are filtered down. The filter material mainly collects coarse dust by inertial collision, and fine dust is mainly collected by diffusion and screening.The dust layer of the filter material also has a specific filtering effect.The effect of HMCN long bag pulsed precipitator is related to many factors, but mainly depends on the filter material.The filter material of HMCN type long bag pulsed precipitator is cloth or felt made of synthetic fiber, fiber or glass fiber.

    Sew cloth or felt into cylinder or flat filter bag as needed.According to the properties of flue gas, the filter material suitable for application conditions is selected.Generally, in the flue gas temperature is lower than 120℃, requires the filter material to have acid resistance and durability, often choose polyester flanna and polyester needle felt;Graphitized glass fiber cloth is mainly used in treating high temperature flue gas (< 250℃).In some special cases, choose carbon fiber filter material.It is very important to control the speed of flue gas passing through filter material in the operation of HMCN type long bag pulsed precipitator.Generally, the filtration rate is 0.5 -- 2m/min, for greater than 0.The 1m particle efficiency can be over , and the equipment resistance loss is about 980 -- I470Pa.

    It is suitable for collecting fine, dry, non - fibrous dust.Filter bag used textile filter cloth or non textile mat is made, using the fabric filter effect of dust filters, gas when the dust into the dust collector, gas particles, dust, such as that of due to gravity settling down, fall into the hopper, contains the fine dust of gas through the filter material, the dust were blocked, the purified gas.

    General new filter material dust removal efficiency is not high enough.Filter material to use after a period of time, due to the screen, collision, stranding, diffusion, electrostatic effect, such as a layer of dust accumulation on the surface of filter bag, at the beginning of the dust layer is called layer, after the movement process, early become the main filter to filter material layer, depending on the role of the first layer, large mesh filter material can also get higher filtration efficiency.

    HMCN type long bag pulse filter draw lessons from domestic and foreign advanced technology, successfully developed a new type of pulse bag dust removal equipment, is on the basis of the conventional pulse bag dust catcher developed a kind of new type, long bag pulse filter bag HMCN type, it not only combines chamber blow and the characteristics of pulse ash removal, overcome the ordinary chamber blow strength is insufficient and the general pulse soot dust again attached faults, and lengthen the filter bag, give full play to the role of the compressed air force clear grey.It is a kind of large dust removal equipment with high dust removal efficiency, small occupation area, stable operation, reliable performance and convenient maintenance, which can be widely used in metallurgy, casting, building materials, mining, chemical industry and other industries.
