[0012] Figure 1 It is the overall structure diagram of the utility model.

[0013] The reference numerals in the drawings of the specification include: air-water separation pipe 1, negative pressure pipe 2, mixing and collecting pipe 3, water outlet pipe 4, and lifting lug 5. DETAILED DESCRIPTION

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Example 1:

[0016] Simple gas-water separation device, such as Figure 1 As shown, it includes an air-water separation pipe 1 arranged with its axis in the vertical direction. The air-water separation pipe 1 is a 4-inch pipe. The upper end of the air-water separation pipe 1 is connected to a negative pressure pipe 2. The negative pressure pipe 2 is a 1.5-inch pipe. The upper right part of the air-water separation pipe 1 is connected to a mixing collection pipe 3 arranged upward and tilted for collecting gas and water. The mixing collection pipe 3 is a 1.5-inch pipe. The lower end of the air-water separation pipe 1 is connected to a U-shaped water outlet pipe 4 arranged in the vertical direction. The water outlet pipe 4 is a 6-branch pipe. The inlet end of the water outlet pipe 4 is connected to the lower end of the air-water separation pipe 1. The height of the water outlet end of the water outlet pipe 4 is 50 mm higher than the lower end of the air-water separation pipe 1. In this embodiment, two hanging ears 5 are evenly fixed around the top of the air-water separation pipe 1 to facilitate hanging the utility model for easy use.

[0017] Taking advantage of the fact that gas has a lower density and is located at the top, while water has a higher density and is located at the bottom, the density difference is used to separate water and gas. The outlet end of the water outlet pipe 4 is set to be 50 mm higher than the bottom of the gas-water separation pipe 1 to ensure that the water level in the gas-water separation pipe 1 can be maintained at a height of 50 mm at any time to prevent overflow from the water outlet when the gas pressure is high. The top negative pressure pipe 2 is connected to the gas extraction and discharge pipeline through a bellows, and the size of the negative pressure is controlled by the valve on the gas extraction and discharge pipeline to correspond to the amount of gas gushing in the borehole, so that water can be discharged normally while the gas is extracted (the water outlet pipe 4 can adopt different pipe diameters according to different water gushing amounts).

[0018] The above is only a specific implementation method of the present invention, but the scope of protection of the present invention is not limited to this. Any technician familiar with the technical field can easily think of changes or replacements within the technical scope disclosed by the present invention, which should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
