An annular jet dedusting system linked with mine aerosol

Abstract

The invention discloses an annular jet dedusting system linked with gas mist for mining. The wind mechanism and the wind collecting mechanism are arranged toward the wind collecting mechanism; the wind increasing mechanism includes an outer tube, the outer tube is provided with an inner tube, a jet outlet gap is formed between the outer wall of the inner tube and the inner wall of the outer tube, and the gap between the jet outlet and the inner wall of the outer tube is formed. The swirling speed increasing device is connected, and the inner wall of the outer tube is provided with an arc surface corresponding to the thickest end of the gradient protrusion, and the arc surface and the thickest end of the gradient protrusion form a jet nozzle, and the jet nozzle and the tube of the inner tube cavities communicate. The dust-laden air flow is injected at high speed through the annular jet outlet gap, so that the external dust-laden gas is forced into the air booster mechanism to flow together with the original high-speed jet flow, and the dust-laden gas is subjected to high-pressure spray and inertial dust collection during the flow process. effect, the dust concentration is effectively reduced.

Description

technical field [0001] The invention relates to the field of gas mist linkage dust removal for mines, in particular to an annular jet dust removal system of mine gas mist linkage. Background technique [0002] With the rapid development of mine mechanized production level, the dust hazards in the mine production process are becoming more and more prominent, and the hazards of pneumoconiosis and dust explosions are constantly escalating, which seriously threatens the safe production of mines and the physical and mental health of miners. [0003] Practices at home and abroad have proved that the use of wet suction dedusting devices in high-dust mine workplaces is an effective method to solve the hazards of high-concentration mine dust, and has played a positive role in the prevention, control and treatment of underground regional hazards. Theoretically, through the dust removal device, the dust clusters in the mine dust production site are strongly extracted to reduce the dust...

AI Technical Summary

Problems solved by technology

[0004] (1) The safety is low. The high-concentration dust-laden air flow enters the dust removal device without dust reduction treatment. When the dust concentration reaches a certain level, it is easy to cause a dust explosion;

[0005] (2) The processing air volume is small, and the dust removal device cannot achieve high-efficiency suction of dust in the work area;

[0006] (3) Insufficient environmental protection. Due to the limited air volume of the dust removal device, in order to improve the dust extraction efficiency, high-power mechanical equipment must be selected. At this time, not only the power consumption is large, but the equipment is running with strong noise, which affects the accuracy of information transmission among underground workers. , prone to liability accidents
