The MDC and PDC coal mill explosion-proof electrostatic bag dust collectors use filter media, have explosion-proof structures, and are equipped with pressure relief devices, which have explosion-proof performance and are suitable for collecting flammable and explosive dust in coal powder preparation systems. The equipment has fewer mechanical action parts, less maintenance workload, and is easy to replace bags. Due to the use of pulsating compartment cleaning, the dust collection efficiency is high and can operate stably for a long time, with a dust collection efficiency of over 99.8%. The PDC ordinary dust collector not only has explosion-proof performance, but also has the same advantages as mentioned above. It can be widely used for dust collection of waste gases from cement, electricity, metallurgy, chemical and other industries. Dust collection can be used for dust collection points such as cement mills, raw material mills, mine crushing, material lifting, and transportation.

Principle of MDC and PDC coal mill explosion-proof electrostatic bag dust collector:

The key factor in aluminum powder explosion is the concentration of aluminum powder, and the way to control aluminum powder explosion is to control the concentration of aluminum powder. The tool used to control the concentration of aluminum powder in the equipment is a dust collector. As long as the dust collector of the shot blasting machine is in good working condition and has good dust removal effect, the aluminum powder concentration of the entire shot blasting cleaning machine equipment will not increase. Therefore, ensuring the good dust removal effect of the dust collector is the key to the normal operation of the equipment. The effectiveness of dust removal mainly depends on the filtering material, and when the filtering material becomes clogged, the dust removal effect will be greatly reduced. When the ventilation and filtration of the filter material are good, the pressure difference between the static pressure chamber and the dynamic pressure chamber of the dust collector will remain stable within a fixed range. Therefore, controlling the pressure difference of the dust collector is a way to control its working state.

Technical characteristics of MDC and PDC coal mill explosion-proof electrostatic bag dust collectors:

Based on this point, an explosion-proof dust collector was invented. The main method is to install a pressure difference controller near the dust collector of the shot blasting cleaning machine without vibration. When the dust collector of the shot blasting machine is blocked for a period of time, the pressure difference detected by the instrument will change. When the detection value exceeds the set upper and lower limits, the pressure difference controller will control the cleaning mechanism of the filter bag of the dust collector to work, such as the vibration or back blowing mechanism to remove the dust on the surface of the filter material of the dust collector, to ensure that the dust collector has a good working condition. When the automatic cleaning still cannot meet the requirements, the differential pressure controller will control the alarm to sound and automatically shut down the equipment to prevent accidents.

To ensure operation, we have also installed a gravity type automatic explosion door at the key position of the shot blasting machine dust collector. This device is generally designed at the top of the shot blasting chamber and dust removal pipeline, in areas with dense dust. After calculation, the device can automatically open the door at the moment of explosion, release the explosion pressure, and avoid injury to equipment and personnel. After unloading, the door automatically closes by gravity.

MDC and PDC coal mill explosion-proof electrostatic bag dust collectors can be widely used for dust collection of working waste gases in coal, iron and stone mines, cement, power, metallurgy, chemical industry, and other industries. Dust collection can be used for dust collection points such as cement mills, raw material mills, mine crushing, material lifting, and transportation.
