Problems solved by technology

Within the construction height of the designed borehole, if there is an aquifer or there is water in the borehole due to cracks, when the borehole comes out of water, the gas drainage pipeline is easily blocked by water, causing the pipeline to be blocked or even blocked, affecting Drain effect
In order to overcome this problem, the existing technology is to use the negative pressure automatic water release device of the gas drainage pipeline, but the water discharge effect is not ideal. Blockage, large amount of maintenance, extremely inconvenient to use on site

Embodiment 1

[0022] A fully automatic water overflow device for a high-level drilling site, the structure of which is as follows Figure 1-3 shown.

[0023] Production of drainage borehole gas-water separator 4, a steel cylindrical container with a diameter of 159mm and a height of 0.6m. There is a nozzle with a diameter of 50mm on the container wall as the borehole interface 2 to connect with the gas drainage borehole 12 in the high-level drilling site 11 There is a nozzle with a diameter of 50 mm on the top of the container as a gas extraction port 1 to connect to the gas extraction pipe 13, and a water discharge port 3 with a diameter of 50 mm is provided at the bottom or lower part of the container.

[0024] Make the rectangular iron box of top open as overflow tank 5, be welded with the water inlet 4 of diameter 50mm in overflow tank 5 side bottom (can be selected according to the drilling hole number in a high position drill field), this water inlet 6 It is connected to the water ou...

Abstract

The invention relates to a full-automatic overflow device for gas extraction by drill holes in a high-positioned drill site, comprising a gas-water separator and an overflow channel. The gas-water separator is provided with pipe orifices respectively communicated with the drill holes and gas extraction pipes in the high-positioned drill site, and the lower part of the gas-water separator is provided with a discharge outlet communicated with the water inlet of the overflow channel through a discharge pipe. The overflow channel is a water pool of which the upper part is of an open, one side of the overflow channel is provided with the water inlet, and the other side of the overflow channel is provided with the water outlet. The full-automatic overflow device in the high-positioned drill site performs the gas-water separation at the position of the drill holes, and then discharges the water through the automatic overflow channel. The device can prevent the reduction of the extraction effect due to the blocking of the pipeline caused by the water or due to the increment of the extraction resistance caused by the water in the pipeline. The device has the advantages of simple structure,and good water discharging effect.

Description

technical field [0001] The invention relates to an automatic water discharge device for gas drainage, in particular to a fully automatic overflow device for drilling holes in a high-level drilling site for gas drainage. Background technique [0002] At present, in high-gas mines or gas-focused areas, drilling is generally carried out in high-level drilling sites, and gas drainage is carried out through drilling to achieve the purpose of gas control or gas utilization. Within the construction height of the designed borehole, if there is an aquifer or there is water in the borehole due to cracks, when the borehole comes out of water, the gas drainage pipeline is likely to be blocked by water, causing the pipeline to be blocked or even blocked. Draw effect. In order to overcome this problem, the existing technology is to use the negative pressure automatic water release device of the gas drainage pipeline, but the water discharge effect is not ideal. Blockage, large amount of...
