Underground dust removal device and operation method

Abstract

The invention discloses an underground dust removal device and an operation method. The underground dust removal device comprises a box body (1), a dust suction fan (2) is installed on a left side panel of the box body (1), an exhaust gas emission grid is arranged on the upper side of a right side panel, and a filtering cleaning device is arranged in the box body. The operation method comprises the steps that the dust suction fan is turned on, the dust is sucked and sent to the filtering cleaning device; a water supply pipe is opened, water is supplied to a water curtain and a cleaning nozzleof the filtering cleaning device, the water curtain is formed on the upper part of a filtering net, and a water film is formed on a filtering grid; when the dust penetrates through the filtering net and the water curtain and the water curtain and the water film formed by the cleaning nozzle under the drive of the wind, the dust is intercepted by the filtering net and the water film and adheres tothe filtering net and then is flushed to the bottom of the box by the water flow formed by the water curtain; and a sewage discharging pipe is opened to discharge the sewage out of the box body. The problems that location limitation is relatively large and flexibility is insufficient in the prior art, and the safety of the site and the health of employees are affected due to the fact that a largeamount of foam or water mist is generated are solved.

Description

technical field [0001] The invention belongs to coal mine underground dust removal technology, in particular to an underground dust removal device and an operation method. Background technique [0002] During the coal mining process, a large amount of dust will be produced. The generation of a large amount of dust not only seriously endangers the health of coal mine workers, but also poses the risk of dust explosion. Dust control is an extremely important part of coal mine safety work. [0003] At present, the closest existing technology is that the underground mining face uses the foam dedusting technology, and uses an automatic dust-proof water curtain device in the main roadway. [0004] In the process of using foam dust removal and dust-proof water curtain, foam dust removal is mainly used on mining equipment, for fixed-point dust removal of dust generated by cutting parts of mining equipment, and dust-proof water curtain is used for fixed positions in main roadways ,...
