Introduction to HMC type pulse single-machine bag filter

The HMC series pulse single-machine dust collector is a small bag filter designed by our company after digesting and absorbing similar products from both domestic and international sources and making improvements. The dust collector comes in six specifications, and each specification can be further divided into two types: the standard ash-carrying type A and the open flange type (without ash hopper) B. Its structure mainly consists of a filter chamber, filter bag, clean air chamber, ash hopper, ash discharge valve, pulse jet ash removal device, and electric control box. The entire box body is of welded construction. The maintenance door is sealed with foam rubber strips to ensure that the dust collector is airtight and leak-proof.

Working Principle:

The air inlet of the HMC dust collector is located on the ash hopper. When the dust-laden gas enters the ash hopper through the air inlet, it first encounters the baffle at the inlet. Due to inertia, coarse dust particles in the gas directly enter the ash hopper, serving as a pre-dust collection function. The gas flow entering the ash hopper then turns upward and passes through the filter bag with a metal skeleton inside. The dust is collected on the outer surface of the filter bag, and the purified gas enters the clean room above the filter bag chamber and is collected in the air outlet pipe for discharge. The indoor dust collection bags are divided into several rows, and each row of dust collection bags is cleaned at a given time interval. When the pulse valve is opened, high-pressure air is sprayed into the filter bag to remove dust from the surface of the filter bag. The pulse blowing width and dust cleaning cycle of each row of filter bags are automatically and continuously controlled by a dedicated dust cleaning program controller

The dust-laden gas enters the filter chamber through the ash hopper (or the lower open flange), while the larger particles directly fall into the ash hopper or silo.

Technical parameters of HMC type pulse single bag filter

Structural characteristics:

The main body of the dust collector consists of four parts: the housing, the filter bag assembly, the pulse jet ash removal device, and the ash discharge device.

The shell is composed of an upper box, a middle box, a dust hopper, and air inlets and outlets.

The filter bag assembly consists of the filter bag, filter bag frame, etc.

The jetting ash removal device consists of an air bag, a jetting pipe, a pulse valve, an electromagnetic control valve, an electronic controller, etc.

The ash discharge device consists of a motor, a reducer, a screw conveyor, and a star-shaped discharge valve.

Pulse valve type I adopts a right-angle pulse valve, while type II adopts a straight-through pulse valve, reducing the resistance of the pulse valve itself and providing a more ideal pulse blowing method.

Main technical performance parameters: See Table (1) for detailed main technical performance parameters

Purpose of HMC type pulse single bag filter

The dust collector adopts a pulse jetting ash removal method. It has the advantages of good ash removal effect, high purification efficiency, large processing air volume, long filter bag life, small maintenance workload, safe and reliable operation, etc. It is widely used in metallurgy, building materials, machinery, chemical industry, mining and other industrial and mining enterprises for dust removal and purification of non-fiber industrial dust and material recovery.
