What are the methods of dust removal for the central dust collection system supplier? from chinahutong's blog

The central dust collection system supplier shall prevent the gas from cooling below the dew point in the pouch room during use, especially when using the central dust collection system under negative pressure. If the far infrared electric heater or heater is installed in the dust collector, or the radiator is added in the bag room, the flue gas temperature of the main engine can be properly raised. Increase the temperature monitoring of dust collector and dust removal system, so as to master the operating conditions of single bag dust collector and prevent condensation. Because the shell often has air leakage, so that the gas temperature in the bag room is lower than the dew point, the filter bag will be damp, resulting in dust is not loose, but sticky attached to the filter bag, the fabric hole is blocked, resulting in dust removal failure, so that the dust collector pressure drop is too large, can not continue to run, some paste bag can not dust.

What are the methods of dust removal for the central dust collection system supplier? Below, give you a detailed introduction:

I. Pulse dust removal: It is mainly to inject compressed air into the filter bag through the Wendian tube to induce the surrounding air in the time, so that the filter bag produces pulse expansion vibration and under the action of reverse airflow, the dust on the dust bag is peeled off.

Two, physical cleaning: mainly rely on artificial or mechanical vibration or high frequency oscillation. The vibration can be used vertical or horizontal two methods, the shock to use a better speed. The advantages of physical cleaning are simple and convenient, but the disadvantages are uneven vibration, low filtration wind speed and great damage to the filter bag.

Three, acoustic cleaning: the main use of acoustic cleaning device to convert the kinetic energy of pressure gas into acoustic wave energy, so that the dust bag to produce additional vibration and achieve the purpose of cleaning. The advantage is technology, low power consumption, little damage to the equipment. The downside is that it costs a lot.

Four, up-wind dust removal: outdoor or circulating air is mainly used to pass through the filter bag in the opposite direction of the dusty air flow, so that the dust block on the filter bag falls off. The upwind ash removal methods are reverse blowing and reverse suction. The former blows air into the bag at positive pressure, while the latter sucks air out of the bag at negative pressure. Dust cleaning air can be supplied by the main fan, or a single back blowing (suction) fan. The advantage of this cleaning method is that the air distribution is more uniform, the disadvantage is that the cleaning strength is small and the wind speed can not be too large.

The service cycle of the central dust collection system supplier is related to the dust concentration of the gas entering the dust collector, the filtration wind speed and the pressure of the air source used for dust cleaning. If the concentration is large, the filtration wind speed is high or the injection pressure is low, the cycle can be shorter. On the contrary, the cycle can be extended appropriately. If the pressure of the air source is above 400kpa, the pulse cycle can be selected as 10-30min, and the specific operation can be adjusted according to the reading of the pressure gauge. The use of separate chamber air pulse jet cleaning, cleaning period is long, low consumption, can double the life of the filter bag and valve disc; The working mechanism of the central dust collection system supplier is that the dust particles are filtered by the dust containing gas through the filter material. The coarse dust is captured by the filter material mainly by inertial collision, while the fine dust is captured by diffusion and screening.
