Mine dust removal method:

Mine dust collectors Generally speaking, there are four ways to deal with dust in the air:

1. Closed dust removal: Closed dust removal is to control the dust in a closed space, which greatly reduces the range of dust activity. Of course, in actual mine dust removal, it is difficult to achieve closed.

2. Filter type dust removal: It uses fiber to filter dust, similar to the principle of filter screens seen in daily life. In the beginning, the filter screen blocked the dust. As the dust accumulated on the filter screen, it became a dust film and continued to hold the dust.

3. Electrostatic dedusting technology: It uses high voltage electricity to discharge the dust, so as to charge the dust and separate the dust in the air under the force of the electric field.

4. Water spray or spray dust removal: Water spray dust removal actually reminds people that the air after rain is exceptionally fresh. In fact, it is similar. However, water spray dust removal will produce sewage, but sewage treatment will be required, so the cost will be greater.

Application scope of mine dust collector:

During actual production, dust is usually generated after various process equipments are operated for a period of time. So how to make the dust production point and emission standard of the mine? This is to control the generated dust point. The following is a brief introduction by Xiaobian to the scope of application of mine dust collectors. I hope it can be helpful to you! With the advancement of technology, the new generation of mine dust collectors has become the dust collector of mines. The main applications are as follows:

First, mine dust collector is suitable for dust removal in mining, crushing and other industries.

2. The mine dust collector is suitable for various dust gases.

3. The mine dust collector can usually be used at room temperature below 120 ℃, and high temperature equipment below 250 ℃ can also be provided. The equipment can be made of carbon steel or stainless steel.

24. Mine dust collector is suitable for crushing and screening of various metal ore dressing, belt conveyor transfer, crushing and screening of stone plants.

Working principle of mine dust collector:

The working principle of the mine dust collector is to enter the dust-containing gas tangentially into the upper space of the filter room. Under the centrifugal force of large particles and condensed dust particles, the ash bucket is spun down along the wall of the barrel. The purified air passes through the wall of the bag, collects in the cleaning room through the filter bag guide on the flower plate, is sucked in by the ventilator, and is discharged into the atmosphere. With the progress of the filtering conditions, dust is attached to the surface of the dust removal bag, and the resistance of the dust removal bag is gradually added. When the upper limit of the resistance of the anti-air blower is reached, the differential pressure transmitter connected to the front and rear interfaces of the dust collector sends a signal to initiate the reaction. Blow to organize the job.

Purification of dust only needs to be performed by a bag filter. The selection of the dust collector directly affects the capture effect of the dust removal system, the power consumption of the dust removal, and whether the entire system can be stably and reliably operated for a long time. The way of the dust collector is complicated, each has its advantages and disadvantages. The key lies in how to learn from each other. Adapt to system technology and dust composition to achieve good results. As for material transportation, a bag filter is more suitable. Its effect of removing fine dust is remarkable, and the emission concentration can be controlled below 20mg / Nm3.
