DMC DMC single pulse single pulse dust collector bag filter is absorbed the original DMCC pulse bag filter, the improvement of the original cinder system that simplifies the structure of the new stand-alone device dust removal unit, the device has an improved treatment capacity, good purification effect features easy operation and maintenance, and mechanical rapping warehouse roof ESP also compared with a working noise, bag long life, no mechanical moving parts to wear, and suitable to be stored in a variety of powder the top of the library, for capturing a variety of small dry non-fibrous dust. Works dusty air from the bottom of the box into the dust precipitator middle coarse particles of dust by its own gravity settling down after falling into the ash bin, fine dust is absorbed by the various effects in the outer wall of the bag, the bag Clean air filtered through the venturi tube into the box is discharged from the outlet, the dust is adsorbed on the outer wall of the bag with the growth of time piled thick, dust resistance increased gradually decreasing the amount of gas processed . In order to keep dust in effective working condition, the pressure loss kept within a certain range, you need to clear out of the bag wall adsorption fouling. Cleaning process is controlled by the device according to requirements issued a directive to each of the electromagnetic pulse valve, open the valve, order each group bag blowing high-pressure air, so the air bag within the compressed air blowing through the venturi tube through the perforations tube into the bag (called primary air), and when the injection of high-speed air flow through the venturi tube - ejector moment, several times in the primary air around the air is induced into the bag at the same time (called secondary air) . Because of this, an air stream and the secondary air filter formed opposite strong reverse flow enters the bag, so to achieve a sharp contraction of the bag at the moment - expansion - contraction, as well as the reverse of a gas stream, by adsorbed Outside the walls of the bag dust cleared down.
