Problems solved by technology
At this time, because the gas extraction device is in a closed state, the gas in the mine cannot be pumped out, which will lead to an increase in the concentration of gas in the mine, seriously threatening the safety of the mine.
[0006] That is, it is currently impossible to discharge the water in the gas drainage pipeline while using the gas drainage pipeline to drain the gas

Embodiment Construction
[0012] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.
[0013] like figure 1 The shown drainage device for the gas drainage pipeline includes a confluence 103 and a water tank 108; the confluence 103 is provided with an air inlet 102, an air outlet 104, a water outlet 107 and a gate valve 106 communicating with the atmosphere in the mine; The air inlet 102 communicates with the previous gas drainage pipeline 101; the air outlet 104 communicates with the next gas drainage pipeline 105; the water outlet 107 is located between the air inlet 102 and the gas outlet 104 and communicates with the water tank 108; the water tank The bottom of 108 is provided with the drain valve 109 that is used for the accumulated water in the water tank 108 is discharged.
[0014] During the process of air and water containing gas gas flowing from the previous section of gas drainage pipeline...

The invention relates to the field of mines and particularly to a drainage device used for a gas pumping and releasing pipeline. The drainage device comprises a converging device and a water tank, wherein the converging device is provided with an air inlet, an air outlet, a water outlet and a gate valve communicated with atmosphere in a mine; the air inlet is communicated with a front section of the gas pumping and releasing pipeline; the air outlet is communicated with a following section of the gas pumping and releasing pipeline; the water outlet is located between the air inlet and the air outlet and is communicated with the water tank; a drain valve used for draining accumulated water in the water tank is arranged at the bottom of the water tank. The drainage device has a simple structure, can drain water and slag soil in the gas pumping and releasing pipeline while gas is pumped and released by the gas pumping and releasing pipeline, and achieves good drainage and slag discharge effects.
Description
technical field [0001] The invention relates to the field of mines, in particular to a drainage device for gas drainage pipelines. Background technique [0002] The gas drainage pipeline is a special pipeline used to drain the gas in the mine to the ground atmosphere. On the working face in the mine, a section of gas drainage pipeline is laid along the working face from the depth of the mine to the outside, and the gas in the depth of the mine is pumped to the ground for utilization. [0003] Because the water content in the mine is relatively large, when the gas drainage pipeline draws the gas deep in the mine, it will inevitably suck the water in the mine into the gas drainage pipeline. In order to discharge the water in the gas drainage pipeline, a water tank is connected between the previous section of the gas drainage pipeline and the latter section of the gas drainage pipeline, and the accumulated water in the pipeline enters the water tank through the confluence. ...
