DMC type single machine bag typeIt is a small bag filter designed by our company based on the improved technology of similar products. The DMC-96 pulse bag single machine dust collector adopts the technology of high-pressure (0.5-0.7MPa) high flow electromagnetic pulse valve to spray and clean the dust from each dust bag one by one. Compared with other single machine dust collectors in China, the DMC-96 pulse bag single machine dust collector has the characteristics of high dust cleaning kinetic energy and dust cleaning. And with its small size, light weight, simple and compact structure, easy installation, and convenient maintenance (external filter type), the DMC-96 pulse bag single machine dust collector is widely used in industries such as building materials, cement, metallurgy, mining, chemical industry, coal, non-metallic mineral powder processing, etc. It is an ideal equipment for environmental dust removal.

This series of single machine dust collectors currently has six specifications, each of which can be divided into two types: standard ash hopper type A and open flange type (without ash hopper) B. Its structure is mainly composed of filter chamber, filter bag, air purifying chamber, ash hopper, ash unloading valve, pulse blowing device, electric control box, etc. The box is all of welded structure, the access door is sealed with foam rubber strips, and the DMC-96 pulse bag single machine dust remover is tight without air leakage.

2、 Dust collector selectionThis single machine has six specifications: 24, 32, 48, 96, 80, 96, 112, and 120, divided into two installation forms to meet the requirements of different occasions. The specific model specifications are as follows:

DMC-96 (A, B)

D - Single machine dust collector

MC - Pulse Spray Type

-96- Number of filter bags 96

(A, B) - A: with ash hopper and ash discharge valve B: flange type

3、 Working principle:

The dusty gas enters the ash hopper through the inlet of the DMC-96 pulse bag single machine dust collector, and enters the dust removal bag chamber through an open flange. The dusty gas is filtered through the filter bag into clean gas and enters the clean air chamber. It is then discharged by the fan through the exhaust port of the clean air chamber. Dust accumulates on the outer surface of the filter bag and continues to increase, causing the resistance of the bag filter to constantly rise. In order to ensure that the equipment resistance does not exceed 1200Pa and the bag filter can work intermittently, it is necessary to regularly apply dust to the filter bag.

Dust cleaning is achieved by using a pulse control device to sequentially activate an electromagnetic pulse valve in a timed manner, causing compressed air (0.5~0.7MPa) inside the bag to be blown out through the nozzle holes (referred to as primary air) and induced by a Venturi tube to generate surrounding air several times the primary air (referred to as secondary air). The air enters the filter bag, causing the dust removal bag to rapidly expand in an instant and shake off the dust with the opposite direction of the airflow. The dust attached to the bag surface separates from the filter bag and falls into the ash hopper (or ash bin). The dust is discharged through the ash discharge valve to achieve the purpose of dust cleaning.
