Problems solved by technology
In addition, hydrogen sulfide is also easy to corrode coal mine underground metal equipment and monitoring and monitoring facilities, increasing the maintenance cost of coal mine equipment and bringing serious safety hazards
The existing control measures for hydrogen sulfide gushing out of the coal discharge place of hydraulic support in coal mines are mainly spraying water mist of alkaline matrix, but it is difficult to form a water film by simple spraying of water mist, and the contact between hydrogen sulfide gas and water mist is limited, only 60% Left and right hydrogen sulfide has been processed, and the hazards of hydrogen sulfide gas are still serious

The invention provides a hydraulic support coal caving gush hydrogen sulfide treatment device. A hydraulic support comprises a base, a stand column, a front protective plate, a front side plate, a rear side plate, a supporting plate and a rear protective plate. One end of the stand column is fixed to the base, and the other end of the stand column is fixed to the front side plate. Every two of the front protective plate, the front side plate and the rear side plate are connected in sequence from front to back. The rear protective plate is connected to the upper portion of the rear end of a top plate inside the rear side plate. The supporting plate is connected to the lower portion of the rear end of a top plate inside the rear side plate. The rear end of the base is connected with a coal drop. The coal drop is located below the rear protective plate. The treatment device comprises a filter net and a spraying device. The filter net is suspended below the rear protective plate and the supporting plate and located above the coal drop. The spraying device is arranged on the hydraulic support and used for performing spraying towards the filter net. According to the hydraulic support coal caving gush hydrogen sulfide treatment device, the hydrogen sulfide treatment efficiency can be remarkably improved, treating fluid waste is avoided, the structure is simple, and operation is convenient.
Description
technical field [0001] The invention belongs to the field of coal mines, in particular to a treatment device for hydrogen sulfide gushing out of coal when a hydraulic support is set. Background technique [0002] At present, the hydraulic supports in coal mines mainly include a base and a front guard plate installed above the base, a front side plate and a rear side plate, wherein the rear of the rear side plate is located above the rear of the base, and the rear of the rear side plate Supported on the base by two front and rear support rods; a rear guard plate is hinged at the rear end of the inner top plate of the rear side plate, and an insert plate is installed in the rear guard plate for coal discharge; at the rear end of the inner roof plate of the rear side plate The lower part is connected with a support plate, and a hydraulic cylinder is installed between the lower end of the support plate and the rear end of the rear guard plate to adjust the height of the rear end...
