[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a pressure vessel gas-liquid separation device, comprising a tank body, the bottom of which is hemispherical, a side box fixedly connected to one side of the tank body, the bottom of which is inclined, and a drain pipe connected to its lower end, and further comprising...

[0006] A pre-separation component is located inside the side box and includes a separation box. The top of the separation box is open, and a servo motor is fixedly installed at the bottom of the side box, with its output end located inside the side box. The output end of the servo motor is fixedly installed in the separation box.

[0007] The re-separation component is located inside the tank and includes a baffle plate. The baffle plate is fixedly connected between the inner walls of the tank and the bottom of the baffle plate and the inner wall of the tube. Flow-blocking separation mechanisms are provided on both sides of the baffle plate.

[0008] Furthermore, a vacuum pump is fixedly installed on the top of the side box. The input end and output end of the vacuum pump are located inside the side box and inside the tank, respectively. The input end of the vacuum pump is fixedly connected to a flow guide shroud, which is located inside the separation box. An inlet pump is fixedly installed on the top of the side box, and its output end passes through the flow guide shroud and is located inside the separation box.

[0009] Furthermore, the outer wall of the flow guide is fixedly connected to an outer ring with an inverted U-shaped vertical cross-section, the top of the separation box is located at the bottom recess of the outer ring, the outer wall of the flow guide is fixedly connected to a sealing ring, the sealing ring is in contact with the inner wall of the separation box, the output end of the air pump is fixedly connected to an annularly arranged air distribution pipe, and the bottom of the air distribution pipe is provided with annularly arranged nozzles.

[0010] Furthermore, the flow-blocking and separation mechanism includes a bent flow-blocking plate and a square box. The bent flow-blocking plate is fixedly connected between the partition and the inner wall of the pipe, and they are arranged vertically at equal intervals. A horizontal plate is fixedly connected between the partition and the inner wall of the pipe. A through hole is provided in the middle of the horizontal plate.

[0014] (1) The high-speed rotation of the separation box centrifuges the gas-liquid mixture. The liquid is thrown onto the inner wall of the side box under the action of centrifugal force and then concentrated at the bottom of the side box and discharged through the drain pipe.

[0015] (2) After the initial separation, the gas-liquid mixture is sprayed out through each nozzle. Multiple bent baffles and the bottom filter screen block the gas-liquid mixture.

[0022] like Figures 1-2 As shown, a pressure vessel gas-liquid separation device includes a tank 1 with a hemispherical bottom for easy centralized liquid discharge. A side box 2 is fixedly connected to one side of the tank 1, with an inclined bottom and a drain pipe 3 connected to its lower end for easy liquid discharge. A bottom pipe 20 is fixedly connected to the bottom of the tank 1, and a top ball 21 communicating with the inside of the tank 1 is fixedly connected to the top of the tank 1. A top pipe 22 is provided on the top of the top ball 21. The top ball 21 facilitates the centralized discharge of gas. Solenoid valves are fixedly connected to the middle of the top pipe 22, the bottom pipe 20, and the drain pipe 3 for easy control of gas or liquid discharge. The device also includes a pre-separation component located inside the side box 2 and a re-separation component located inside the tank 1.

[0023] like Figures 1-4 As shown, in order to perform a pre-separation operation on the gas-liquid mixture, the pre-separation assembly includes a separation box 4 with an open top. A servo motor 5 is fixedly installed at the bottom of a side box 2, with its output end located inside the side box 2. The output end of the servo motor 5 is fixedly installed in the separation box 4. A vacuum pump 8 is fixedly installed at the top of the side box 2, with its input and output ends located inside the side box 2 and the tank 1, respectively. A flow guide shroud 9 is fixedly connected to the input end of the vacuum pump 8 and is located inside the separation box 4. An inlet pump 10 is fixedly installed at the top of the side box 2, with its output end passing through the flow guide shroud 9. Inside the separation box 4, the outer wall of the flow guide shroud 9 is fixedly connected to an outer ring 11 with an inverted U-shaped vertical cross section. The top of the separation box 4 is located at the bottom recess of the outer ring 11. When the separation box 4 rotates, its top rotates inside the outer ring 11, which increases the rotational stability of the separation box 4. The outer wall of the flow guide shroud 9 is fixedly connected to a sealing ring 12. The sealing ring 12 fits against the inner wall of the separation box 4, which increases the effect during the initial separation. The output end of the air pump 8 is fixedly connected to a ring-shaped air distribution pipe 13. The bottom of the air distribution pipe 13 is provided with a ring-shaped arrangement of nozzles 14. Multiple nozzles 14 spray out to facilitate the spraying of gas.

[0024] like Figure 3 and 4As shown, to improve the separation effect of the gas-liquid mixture, the re-separation component includes a baffle 6, which is fixedly connected to the inner wall of the tank 1. The baffle 6 can increase the residence time of the gas-liquid mixture inside the tank 1. A filter screen 7 is connected between the bottom of the baffle 6 and the inner wall of the tube. The filter screen 7 can adsorb the liquid in the gas-liquid mixture. Flow-blocking separation mechanisms are provided on both sides of the baffle 6. The flow-blocking separation mechanism includes a bent flow-blocking plate 15 and a square box 16. The bent flow-blocking plate 15 is fixedly connected between the baffle 6 and the inner wall of the tube, and it is arranged vertically at equal intervals. Multiple bent flow-blocking plates 15 are arranged vertically at equal intervals. The flow plate 15 allows the gas-liquid mixture to collide with it, blocking the liquid. A horizontal plate 17 is fixedly connected between the partition plate 6 and the inner wall of the tube. A through hole 18 is provided in the middle of the horizontal plate 17. A square box 16 is fixedly connected to the top of the horizontal plate 17. The interior of the horizontal plate 17 is provided with a channel 19 communicating with the through hole 18. The channel 19 is continuously bent. The bent channel 19 can increase the time the gas-liquid mixture spends inside and increase the number of collisions, thereby improving the separation effect. Furthermore, intermittently distributed moisture-absorbing cotton can be provided inside the channel 19 to improve the moisture absorption effect on the gas-liquid mixture.

[0025] In practical use, the inlet pump 10 is turned on to introduce the gas-liquid mixture to be separated into the separation box 4. Then, the servo motor 5 is turned on to make the separation box 4 rotate at high speed to centrifuge the gas-liquid mixture. Under the action of centrifugal force, the liquid is thrown onto the inner wall of the side box 2 and then flows to the bottom of the side box 2. The liquid is discharged through the drain pipe 3 under the guidance of the bottom wall of the side box 2. The suction pump 8 is turned on to extract the gas-liquid mixture after the initial separation and spray it out through the nozzles 14 on the gas distribution pipe 13. Multiple bent baffles 15 separate the gas and liquid mixture. The mixture is blocked, and the gas-liquid mixture continues to flow downwards and is blocked and adsorbed again by the filter screen 7. Then the gas-liquid mixture enters the inside of the tortuous channel 19. The collision between the gas-liquid mixture and the inner wall of the channel 19 can further reduce the liquid in the gas-liquid mixture. The inside of the channel 19 can also be provided with intermittently distributed moisture-absorbing cotton to improve the moisture absorption effect of the gas-liquid mixture. Through the above operation, the gas-liquid mixture can be efficiently separated. The liquid finally concentrates at the bottom of the tank 1 and is discharged through the bottom pipe 20, while the gas is discharged through the top pipe 22.
