Gas-water separation, water discharging and slag discharge integrated device for drill hole in gas extraction crossheading drill site

Abstract

The invention relates to a gas-water separation, water discharging and slag discharging integrated device for a drill hole in a gas extraction crossheading drill site. The device comprises a gas-water separator and a water discharger, wherein a pipe orifice respectively communicated with the drill hole and a gas extraction pipe in the crossheading drill site is formed on the gas-water separator; the lower part of a container is provided with a water discharge hole; the bottom part of the container is provided with a slag discharge hole; a liquid level observation pipe is arranged out of the container; a water inlet and a gas outlet valve are formed on the top part at one end of the water discharger; a gas inlet valve is arranged on the top part at the other end of the water discharger; and a water discharge valve is arranged on the bottom part of the water discharger. By using the gas-water separation, water discharging and slag discharging integrated device for the drill hole in the gas extraction crossheading drill site provided by the invention, gas-water separation is implemented at the drill hole and then the water is discharged through the water discharger, so that reduction in extraction effect caused by a reason that an extraction pipeline is blocked by water or extraction resistance is increased due to water in the pipeline can be prevented. The device has a simple structure and a good water discharging effect.

Description

technical field [0001] The invention relates to a gas drainage and slag discharge device, in particular to an integrated device for gas-water separation, water discharge and slag discharge in a gas drainage drilling site. Background technique [0002] At present, in high-gas mines or gas-focused areas, drilling is carried out in down-channel 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 maint...

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
