Pulse Jet Bag Filter Type DMCThis is a compact bag dust collector designed and improved by our factory through the digestion and absorption of similar product technology. It employs a high-pressure (0.5～0.7MPa) large flow rate pulse valve to sequentially blast clean each filter bag, offering greater cleaning kinetic energy and unique cleaning characteristics compared to other domestic single machines. It is also compact, lightweight, and structurally simple, making installation easy and maintenance convenient (external filtration). It is widely used in systems for dust gas purification and treatment in industries such as building materials, metallurgy, mining, chemicals, coal, and non-metallic mineral powder processing, and is an ideal equipment for environmental protection and dust removal.

The DMC type pulse dust collector currently comes in six sizes, with each size available in two types: Standard with hopper type A and open flange type (no hopper) B. The structure mainly consists of the filter chamber, filter bags, clean air chamber, hopper, ash discharge valve, pulse jet unit, electric control box, etc. The housing is entirely made of welded construction, with the inspection door sealed using foam rubber strips, ensuring the dust collector is airtight and leakproof.

This unit is available in six specifications (32, 48, 64, 80, 96, 112) and comes in two installation types to meet various usage requirements. Specific model descriptions are as follows:

DMC-32(AB)

D - Single Machine Dust Collector

MC - Jet Pump

-32 - 32 filter bags

(A) - A: With ash hopper and ash unloading valve B: Flanged

DMC-type Pulse Jet Bag Dust Collector Working Principle:

Dust-laden gas enters the ash hopper through the intake port and then flows into the filter bag chamber via an open flange. The gas passes through the filter bags to become clean air, which then enters the clean air chamber and is exhausted by the fan. Dust accumulates on the outer surface of the filter bags and continues to increase, causing the resistance of the dust collector to rise continuously. To ensure the equipment resistance does not exceed 1200Pa, the dust collector can operate intermittently, and the dust on the filter bags needs to be cleaned regularly. Cleaning is achieved by the program controller timing the sequence of the pulse valve, causing compressed air (0.5~0.7MPa) inside the bag to be ejected through the nozzle (known as the primary air). This air is then induced to mix with several times the volume of surrounding air through a Venturi tube (known as the secondary air), entering the filter bags to cause them to急剧膨胀 momentarily. This is accompanied by the reverse action of the airflow, which shakes off the dust, causing the dust adhering to the bag surface to fall off and into the ash hopper (or ash storage), from where the dust is discharged through the ash discharge valve, achieving the cleaning purpose.
