For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0023] See also Figure 1-Figure 3 The utility model provides a closed-loop gas-liquid separator, comprising an inlet section 1, a first gas-liquid separation plate 2 detachably arranged at the upper end of the inlet section 1, a first cylinder section 3 detachably arranged at the upper end of the first gas-liquid separation plate 2, a second gas-liquid separation plate 4 detachably arranged at the upper end of the first cylinder section 3, a second cylinder section 5 detachably arranged at the upper end of the second gas-liquid separation plate 4, a third gas-liquid separation plate 6 detachably arranged at the upper end of the second cylinder section 5, a third cylinder section 7 detachably arranged at the upper end of the third gas-liquid separation plate 6, a fourth gas-liquid separation plate 8 detachably arranged at the upper end of the third cylinder section 7, and an outlet section 9 detachably arranged at the upper end of the fourth gas-liquid separation plate 8. The inlet section 1 is connected to a three-way pipe, which can be passed with a gas-liquid mixed medium. When the gas-liquid separation is completed, the liquid flows into the three-way pipe from the bottom, and the other pipe opening of the three-way pipe is opened as a liquid discharge port.

[0024] The gas-liquid mixed medium enters from the inlet section 1, and the first gas-liquid separation plate 2, the second gas-liquid separation plate 4, the third gas-liquid separation plate 6 and the fourth gas-liquid separation plate 8 form a multi-layer separation structure, which circulates alternately and blocks the liquid after repeated collisions. The gas phase goes out from the outlet section 9, and the liquid is discharged from the bottom. It has the function of multi-layer gas-liquid separation and the gas-liquid separation effect is good. A few more gas-liquid separation plates can be set according to the on-site working conditions, and the cylinder section can be added simultaneously.

[0025] like Figure 1-Figure 3 As shown, a first flange 10 is provided on the outer edge of the first gas-liquid separation plate 2. The first gas-liquid separation plate 2 is an upwardly protruding cone. The first gas-liquid separation plate 2 is provided with a plurality of side grooves 201 that penetrate the first gas-liquid separation plate 2 along the axial direction. The first gas-liquid separation plate 2 has the same structure as the third gas-liquid separation plate 6, and the flange connection facilitates installation and disassembly.

[0026] Furthermore, the top angle of the first gas-liquid separation plate 2 is 130°-140°, and optimally, the top angle of the first gas-liquid separation plate 2 is 135°. When the top angle of the first gas-liquid separation plate 2 is 130°-140°, the droplet blocking effect is good, and at the same time, the gas can be guided from the side groove 201 of the first gas-liquid separation plate 2 into the second gas-liquid separation plate 4, and the side groove 201 is close to the bottom outer edge of the first gas-liquid separation plate 2.

[0027] like Figure 1-Figure 3 As shown, a second flange 11 is provided on the outer edge of the second gas-liquid separation plate 4, and the second gas-liquid separation plate 4 is a downwardly concave trapezoidal cone structure. A center groove 401 is provided in the center of the second gas-liquid separation plate 4 and penetrates the second gas-liquid separation plate 4 axially. The second gas-liquid separation plate 4 has the same structure as the fourth gas-liquid separation plate 8, and the flange connection facilitates installation and disassembly.

[0028] Furthermore, the angle between the outer peripheral side of the second gas-liquid separation plate 4 and the horizontal plane is 20°-25°, and optimally, the angle between the outer peripheral side of the second gas-liquid separation plate 4 and the horizontal plane is 22.5°. The second gas-liquid separation plate 4 guides the gas to go out to the central groove 401 of the second gas-liquid separation plate 4, and at the same time, the second gas-liquid separation plate 4 blocks the liquid droplets, so that the gas changes its flow direction from the first layer to the second layer, thereby separating the gas and the liquid. The gas-liquid separation principle of the third gas-liquid separation plate 6 and the fourth gas-liquid separation plate 8 is the same as that of the first gas-liquid separation plate 2 and the second gas-liquid separation plate 4, and the gas-liquid separation effect is good after multiple layers of separation.

[0029] like Figure 1-Figure 3 As shown, the ratio of the inner diameter of the central groove 401 to the inner diameter of the second flange 11 is 1:(3-4), which can ensure that the liquid can be blocked while the gas flows.

[0030] like Figure 1-Figure 3 As shown, the number of the side grooves 201 is 4, and the 4 side grooves 201 are evenly arranged around the circumference. The shape of the side grooves 201 is an arc strip, and the width of the side grooves 201 is generally 10-15 mm. This can ensure that the liquid can be blocked when the gas flows, and a large amount of liquid will not be brought out while also ensuring the flow of gas.

[0031] The above embodiments are merely descriptions for clearly illustrating the present invention, and are not limitations on the implementation methods. For technicians in the relevant field, other different forms of changes or modifications can be made based on the above descriptions. It is not necessary and impossible to list all the implementation methods here, and the obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
