Gas dust catcher

Abstract

The invention relates to a gas dust catcher comprising a sleeve, a gas dust catching box and a shunt box. The gas dust catching box is of an empty box structure, a sleeve joint is arranged just above the center of the gas dust catching box and is connected with the sleeve by a machined inner thread; the middle part of the gas dust catching box is provided with a dust-proof spraying water pipe fast joint, and the side surface of the lower part of the gas dust catching box is provided with an incline lower slag outlet. The shunt box is of an empty box structure, the top of the shunt box is provided with a gas exhausting pipe and is connected with the gas exhausting pipe through a hose; the side surface of the middle part of the shunt box is provided with a granulating slag and gas inlet pipe which is connected with a slag outlet fast joint of the gas dust catching box; and a granulating slag outlet pipe is arranged at the bottom of the shunt box. The gas dust catching box is used for collecting gas and granulating slag discharged from a bore hole together, the gas and the granulating slag are discharged from the slag outlet into the shunt box for shunting, and the shunt box is used for extracting the methane gas and discharging the granulating slag. The gas dust catcher disclosed by the invention has the advantages of reasonable structure, strong process adaptability, safety, reliability, convenience of assembly and disassembly, good disaggregation performance, convenience of moving and the like.

Description

technical field [0001] The invention relates to the technical field of coal mine safety facilities, in particular to processing equipment for coal mine gas dust. Background technique [0002] At present, when drilling underground in high-gas coal mines, safety accidents such as gas injection holes and overruns often occur. With the continuous increase of mine production, gas control is particularly important, and drainage drilling is playing an increasingly important role as an important means of regional control. At present, during the drilling process of many mines, the blowout holes through the coal seam are serious, resulting in the phenomenon of "double high" of gas. safe production. At the same time, because many mines generally promote the method of compressed air powder discharge, the dust seriously exceeds the standard during the construction process, especially the dust concentration in the return air flow is as high as 318mg / m 3 , seriously affecting the physic...

Problems solved by technology

At present, during the drilling process of many mines, the blowout holes through the coal seam are serious, resulting in the phenomenon of "double high" of gas. production safety

At the same time, because many mines generally promote the method of compressed air powder discharge, the dust seriously exceeds the standard during the construction process, especially the dust concentration in the return air flow is as high as 318mg / m 3 seriously affect the physical and mental health of employees
