HMC type pulse single machine dust collector

HMC pulse single machine dust collector is widely used for dust removal and purification of various process systems and material recovery in industries such as metallurgy, building materials, machinery, chemical engineering, and mining.

The HMC type pulse single machine dust collector adopts the cleaning method of pulse blowing. It has the advantages of good dust cleaning effect, large purification and processing air volume, long filter bag life, low maintenance workload, and operation. Widely used for dust removal, purification, and material recovery of non fibrous dust and industrial dust in various industrial and mining enterprises such as metallurgy, building materials, machinery, chemical engineering, and mining.

Characteristics of HMC pulse single machine dust collector:

1. The HMC type single machine pulse dust collector body consists of four parts: housing, filter bag assembly, spray cleaning device, and ash discharge device.

2. The shell of HMC type single machine pulse dust collector consists of an upper box, a middle box, an ash hopper, and inlet and outlet ports.

3. The HMC type single machine pulse dust collector filter bag assembly consists of filter bags, filter bag frames, etc.

4. The HMC type single machine pulse dust collector spray cleaning device consists of an air bag, spray pipe, pulse valve, electromagnetic control valve, electric control instrument, etc.

5. The HMC type single pulse dust collector ash discharge device consists of a motor, a reducer, a screw conveyor, and a star shaped discharge valve.

6. The HMC type single machine pulse dust collector pulse valve type I adopts a right angle pulse valve, and type II adopts a straight pulse valve, reducing the resistance of the pulse valve itself, which is an ideal pulse spraying method.

The working principle of HMC pulse single machine dust collector:

When working, the dust enters the ash hopper through the air inlet or enters the filter bag chamber through an open flange. The filter bag filters the dust, and the clean air enters the clean air chamber through the filter bag. Then, it is drawn out to the atmosphere by the fan of the pulse single machine dust collector, and the dust will fall onto the surface of the filter bag. The resistance of the filter bag dust collector will continue to rise, so we need to regularly clean the dust on the filter bag. When cleaning the dust, the program controller will activate the pulse valve in a timed sequence to spray through the blowing hole and induce several times the surrounding air through the Venturi tube, and shake off the dust with the reverse effect of the airflow to achieve the purpose of cleaning.

The HMC type pulse single machine dust collector applies the technology of high flow pulse valve spraying and cleaning dust through filter bags one by one. Compared with other single machines in China, it has the characteristics of high cleaning energy and cleaning dust. In addition, it has the characteristics of simple and compact structure, easy installation, and convenient maintenance. So it has a wide range of applications in industries such as mining, chemical, coal, and non-metallic mineral powder processing.

The HMC type pulse single machine dust collector is designed and manufactured by our company after digesting and absorbing the technology and improving the product. During operation, it enters the ash hopper through the air inlet or enters the filter bag chamber through an open flange. The filter bag filters the dust, and the clean air enters the clean air chamber through the filter bag. Then, it is drawn out into the atmosphere by the fan of the pulse single machine dust collector, and the dust will fall onto the surface of the dust removal filter bag. The resistance of the filter bag dust collector will continue to rise, so we need to regularly clean the dust on the filter bag. During dust removal, the program controller will start the pulse valve in a timed sequence to spray through the blowing hole and induce surrounding air several times that of the flash wind through the Venturi tube, accompanied by the reverse airflow. The function is to shake off dust and achieve the purpose of cleaning.

Design and selection steps for HMC type pulse single machine dust collector:

1. Determine the processing air volume of the bag filter

The air volume of HMC type pulse single machine dust collector refers to the operating air volume. If the given air volume is the standard operating air volume, it should be converted into the operating air volume.

Determine the dust concentration of the bag filter

At the beginning, it should meet the standards. Some cities, regions, and enterprises require low concentrations, and in many cases, there are stricter requirements for dust emission concentration: toxic dust; Turbine intake purification; Waste incineration exhaust gas; Gas purification for large blast furnaces.

Determine operating temperature

The upper limit should be lower than the long-term usage temperature allowed by the selected filter material, and the lower limit should be 15-20 ℃ higher than the dew point temperature. When the flue gas contains acidic gases, the dew point temperature is high, and special attention should be paid when designing dust collectors.
