The dust collector of the crusher is installed with dust collection device at the dust point, and the dust is sucked into the dust collector box of the crusher through negative pressure for purification treatment, so as to separate the dust from the clean air.

The dust collector of mine crushing system uses centrifugal fan to produce negative pressure area at the dust sealing cover, and inhales the dust into the dust removal equipment. The pulse bag filter is equipped with dust removal cloth bag. When the dust gas passes through the filter bag, the dust is blocked and separated, and the purified gas is discharged through the fan.

In dry rock drilling without dust control measures, the dust concentration of working face can reach hundreds or thousands of milligrams per meter. When there is no dust prevention measures in underground crushing chamber, the dust concentration can reach several thousand milligrams per meter. The mine dust collector should be suitable for the characteristics of the mine. It is required to be simple in structure, small and compact in size, easy to move, moisture-proof and durable. When the comprehensive dust control measures adopted in each working procedure still fail to meet the requirements, it is necessary to take personal protection.

Dust prevention of mine crushing: on the basis of airtight equipment, the combined measures of wet dust prevention and mechanical dust removal can be adopted for the dust generated by various crushing equipment. The purification equipment of mechanical dust removal adopts bag type dust collector or wet type dust collector. Wet dust collector should be selected for dust removal of underground crushing chamber. When the exhaust air of dust removal system can not be discharged to return air roadway or ground, but can only be discharged locally, the exhaust air shall be treated by filter.

Mine perforation dust prevention: a large amount of dust is produced during the operation of the open-pit drilling rig. Measures such as air-water mixed wet rock drilling inside the hole, dry dust catching outside the hole and wet dust catching can be adopted. Because of the high initial dust concentration, two-stage purification of cyclone and bag filter is needed.

It is suitable for purification of dust gas and material recovery in metallurgy, building materials, cement, machinery, chemical industry, electric power and light industry.

The raw gas (260 ℃) from the raw gas main pipe enters into the lower box of the bag filter through the branch pipe. After mechanical separation, the gas is filtered upward through the cloth bag, and the fine dust is attached to the outer surface of the filter bag. The clean gas is collected into the upper box through the filter bag, and then enters into the hot blast stove through the clean gas branch pipe and the main pipe. When the filtering time is up, with the increase of dust on the surface of the filter bag, the resistance of the dust collector will rise. When the resistance rises to the value, the electrical control system will send out the ash cleaning signal, the pneumatic butterfly valve and upper ball valve of the outlet branch pipe will automatically close, the pulse valve will open, the nitrogen from the cylinder will be injected from the bag mouth through the injection pipe, and the filter bag will expand rapidly.

The dust on the outer surface of the filter bag is shaken off and falls into the conical ash hopper at the lower part. At the end of the pulse valve injection, the dust collector continues to remain static, so that the fine dust in the cylinder has a static settlement process. At the end of this process, the outlet branch pneumatic butterfly valve and the upper ball valve are opened, the dust collector enters the normal filtering state, and the lower ball valve is opened through the impeller feeder The dust cleaning process of a box, the opening and closing of each valve in the above process, and the dust concentration test of a single box are all controlled by PLC system, so that the repeated work can purify the raw gas.

 

4.Dust collector in iron and steel plant

The filter bag made of porous filter cloth is used to separate the dust particles from the flue gas flow. When working, the flue gas flows through the filter bag from the outside to the inside, and the dust particles are blocked outside the filter bag.

The iron and steel industry is a major air polluter. The waste gas management of iron and steel industry implements the principle of comprehensive management. Efforts should be made to reduce energy consumption and raw material consumption, which is one of the fundamental ways to increase the emission of waste gas; the process, adopted process and equipment should be innovated to increase the emission of waste gas from consumption process; energy-saving management methods and equipment should be adopted to strengthen the management and recovery of waste gas; comprehensive use should be vigorously carried out.

At the present stage, a large number of flue gas will be discharged from the sintering machine of large steel plants in China, which will contain nitrogen, sulfur dioxide, dioxin, dust and other substances. Taking the sintering machine of 280 square meters as an example, the content of dust discharged into the atmosphere is 150mg / Nm3. According to this calculation, it will cause great pollution to the environment. At present, China has formulated detailed requirements and standards for energy conservation and emission reduction, and put forward suggestions for environmental protection According to the current standard of our country, the dust concentration discharged into the atmosphere is less than 50mg / Nm3, and the bag filter is an important part to achieve this requirement.
