Device and method for simultaneously treating hydrogen sulfide and dust in mine

Abstract

The invention discloses a device and method for simultaneously treating hydrogen sulfide and dust in a mine, and belongs to the technical field of coal mine safety production. The device comprises an air door, a spraying unit, a feeding unit and a packing layer, the air door is installed in an underground roadway of the coal mine and is divided into two layers of a front air door and a rear air door, the interior of the air door is hollow, and the front air door and the rear air door are each in a grid shape; the spraying unit comprises a first spraying unit and a second spraying unit, the first spraying unit is used for removing the dust in mine wind current, and the second spraying unit is used for removing the hydrogen sulfide in the mine wind current. According to the device for simultaneously treating the hydrogen sulfide and the dust in the mine, the spraying unit can make a liquid be atomized and increase the number of times of contact between the liquid and the wind current, the packing layer is filled with pulling rings to increase the contact area of gas and the liquid, so that the effect that alkali absorbs the hydrogen sulfide is enhanced; and the device has the function of purifying the hydrogen sulfide gas in the coal mine, the working environment of the mine can be improved, and potential safety hazards are eliminated.

Description

technical field [0001] The invention relates to the technical field of coal mine safety production, in particular to a device and method for simultaneously controlling hydrogen sulfide and dust in mines by using fine water mist and alkali spray. Background technique [0002] As the coal mining process proceeds, the hydrogen sulfide gas attached to the coal seam, especially the hydrogen sulfide gas in the high-sulfur coal seam, will gush out and then enter the wind flow. Since hydrogen sulfide is one of the poisonous and harmful gases in coal mines, It will cause great harm to the personal safety and health of coal mine workers, and even cause death. In our country, coal mines die from hydrogen sulfide poisoning every year. In the past forty years, mines with high content of hydrogen sulfide (relative to the safe concentration) have appeared in my country, which poses a great threat to safe production. [0003] In order to solve the technical problems in the above-mentioned ...

Problems solved by technology

[0004] However, the above-mentioned patents mainly focus on the treatment of the abnormal enrichment of hydrogen sulfide gas in the coal seam, without considering the treatment of the harmful gas hydrogen sulfide in the mine wind flow
