Description

Technical Field

[0001] The utility model belongs to the technical field of coal seam gas extraction equipment, and particularly relates to a gas-water separation device for a gas extraction pipeline. Background Art

[0002] Gas extraction is a crucial step in reducing the incidence of coal mine gas accidents and ensuring safe coal mine production. Coal seam gas extraction involves drilling extraction holes into coal seams and gas-rich areas, connecting these holes to specialized pipelines, and extracting and utilizing the gas from the coal seams and goafs through negative pressure. Coal seam gas extraction not only reduces gas outbursts during coal mining, preventing gas accumulation, overshooting, and explosions, but also allows gas to be utilized for energy conservation and emission reduction.

[0003] During the underground gas extraction process, some coal slag, rock particles and accumulated water exist in the extraction borehole, which enter the extraction pipeline with the air flow under the action of negative pressure. If the accumulated water and coal slag in the extraction pipeline are not dealt with in time, the gas extraction pipeline will be blocked, affecting the effect of gas extraction and posing a huge safety hazard.

[0016] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0017] like Figure 1 As shown, a gas-water separation device for a gas extraction pipeline includes a tank body 8 suspended and connected to the bottom of a tunnel roof 1 by a first chain 13 and a second chain 14. A plurality of water inlets are provided on the top of the tank body 8, one of which is connected to a drain pipe 15. The top of the drain pipe 15 is connected to the extraction pipeline 2 through a tee 3. A first valve 4 is provided on the side of the drain pipe 15, and a second valve 9 and a third valve 10 are respectively provided on the lower part of the side surfaces at both ends of the tank body 8.

[0018] In one embodiment, the first chain 13 and the second chain 14 have different lengths. In specific use, the first chain 13 can be longer and the second chain 14 can be shorter, or the second chain 14 can be longer and the first chain 13 can be shorter. This is not limited to this, as long as the tank body 8 is tilted when it is suspended and installed.

[0019] In one embodiment, a first clamp 11 and a second clamp 12 are respectively sleeved on the outer surfaces of both ends of the tank body 8 , the first chain 13 is connected to the first clamp 11 , and the second chain 14 is connected to the second clamp 12 .

[0020] In one embodiment, the water inlet includes a first water inlet 5, a second water inlet 6, and a third water inlet 7, which are spaced apart at the top of the tank body 8. In actual use, the drain pipe 15 can be connected to any water inlet according to the needs of use, thereby facilitating the separation of gas and water.

[0021] In one embodiment, the extraction pipeline 2 is composed of two sections, and the two sections are connected to the two horizontal holes of the tee 3 respectively.

[0022] Working principle of the present utility model: During use, the tank body 8 is connected to the first chain 13 and the second chain 14 through the first clamp 11 and the second clamp 12 and is suspended on the tunnel roof 1. In order to facilitate drainage, the first chain 13 and the second chain 14 are of different lengths, so that the tank body 8 is tilted, and the extraction pipeline 2 is connected to the drainage pipe 15 through the tee 3. In actual use, the drainage pipe 15 is selected to be connected to any one of the first water inlet 5, the second water inlet 6 and the third water inlet 7 according to the actual conditions on site. Under normal extraction conditions, the first valve 4 is opened, the second valve 9 and the third valve 10 are closed, and water and coal slag enter the tank body 8 through the drainage pipe 15 under the action of their own gravity. During drainage, the first valve 4 is closed first, and then the third valve 10 is opened to balance the pressure. Finally, the second valve 9 is opened to discharge the accumulated water in the tank body 8. After drainage is completed, the second valve 9 and the third valve 10 are closed, and the first valve 4 is opened. By controlling the opening and closing of the valve, the gas and water in the extraction pipeline can be effectively separated. The operation is simple, and the gas and water in the pipeline can be effectively separated, which is convenient for use.
