[0025] Specifically, through the setting of the gas-water separation tank 1, during the mining process, if a blowout occurs and the well fluid flows out, it can enter the gas-water separation tank 1 for gas-water separation, separate the natural gas and water contained in the well fluid, and control the flow direction of the overflowed groundwater to control the well fluid within a safe level, which is beneficial to protecting the natural gas mining equipment. When the well fluid enters the gas-water separation tank 1, the lighter gas will pass through the return plate 101 upward, while the water will flow downward, and then the separated water will be led out through the outlet pipe 104.

[0026] The other end of the pump tube 105 is installed with a pump body 6, and the left and right sides of the pump body 6 are connected with connecting pipes 7, the output end of the connecting pipe 7 is installed with a control valve 8, and the output end of the control valve 8 is connected with a diverter box 9, the interior of the diverter box 9 is provided with an inner cavity 901, and the interior of the inner cavity 901 is installed with a movable valve block 902, and one side of the movable valve block 902 is installed with a telescopic cylinder 903, the movable valve block 902 and the inner cavity 901 are slidably connected, and the outer shape of the movable valve block 902 is triangular, and the bottom of the left and right sides of the diverter box 9 are connected with vertical pipes 10, and the vertical pipes 10 are connected to the bottom of the left and right sides of the diverter box 9. The lower end of 10 is connected to a mainstream pipe 11, the surface of the mainstream pipe 11 is connected to a water pipe 12, a diverter pipe 13 is installed at the output end of the water pipe 12, and the left and right sides of the diverter pipe 13 are connected to straight pipes 14, the diverter box 9 is connected to the mainstream pipe 11 through the vertical pipe 10, the mainstream pipe 11 is connected to the diverter pipe 13 through the water pipe 12, a butterfly valve 15 is installed on the symmetrical center line of the diverter pipe 13, the surface of the straight pipe 14 is connected to a water distributor pipe 16, and the surface of the water distributor pipe 16 is installed with a switch valve 17, and one end of the switch valve 17 is provided with a water outlet 18;

[0027] Specifically, the water outlet pipe 104 is connected to the pump body 6 by the pump pipe 105. After the water in the gas-water separation tank 1 is pumped out, it is transported to the inside of the diverter box 9 through the connecting pipe 7, and a control valve 8 is installed on the connecting pipe 7 to control the opening and closing of the connecting pipe 7, so as to facilitate the control operation of the water flow. After the water is diverted by the diverter box 9, it enters the mainstream pipe 11 through the vertical pipe 10, and enters the straight pipe 14 through the mainstream pipe 11 and the water pipe 12. Then, the switch valve 17 of the water distributor pipe 16 connected to the straight pipe 14 is opened to separate and discharge the water, thereby achieving water diversion control.

[0028] The working principle of the utility model is:

[0029] When using the utility model, first, liquid enters the gas-water separation tank 1 through the air inlet 2, water will flow downward and be stored at the bottom of the gas-water separation tank 1, and the mixed part of the natural gas will encounter the return plate 101 and then flow upward, through the gas distribution pipe 102 and the exhaust pipe 103, and be discharged from the exhaust port 4, thereby realizing the pretreatment of the liquid and facilitating the subsequent water separation operation. Secondly, water will enter the connecting pipe 7 through the water outlet pipe 104 and the pump pipe 105, and is transported into the inner cavity 901 inside the diverter box 9 by the connecting pipe 7. The inner cavity 901 of the diverter box 9 adopts a T-shaped structure design. When the telescopic cylinder 903 drives the movable valve block 902 to move, it moves to the left, and the right side of the inner cavity 901 will be opened. Conversely, the left side is opened, and the left and right sides of the inner cavity 901 are respectively connected to a group of vertical pipes 10, and a group of vertical pipes 10 corresponds to a group of straight pipes 14. For example, the inner cavity After the left side of 901 is opened, it will enter the corresponding main pipeline 11 along the vertical pipe 10 connected on the left side. The middle section of the main pipeline 11 is closed and isolated by a valve, and enters the water pipe 12 through the main pipeline 11, and then enters the diverter pipe 13 through the water pipe 12, and enters the corresponding straight pipe 14 through the diverter pipe 13. The operation on the right side of the inner cavity 901 is the same as above. In this way, the left and right straight pipes 14 and the water distributor pipe 16 work alternately. Secondly, when the movable valve block 902 is located in the middle of the inner cavity 901, the left and right sides of the inner cavity 901 are opened to achieve simultaneous operation, so that both alternating work and all work can be operated, the operation is more flexible and the selectivity is better. Then, it enters the straight pipe 14 through the vertical pipe 10, and then opens the switch valve 17 of the water distributor pipe 16 connected to the straight pipe 14 to drain the water, thereby achieving water diversion control.
