[0007] Further optimization: the axis of the air inlet is located on one side of the center line of the vertical separator tank body, and the outer surface of the air inlet is tangent to the outer surface of the vertical separator tank body.

[0008] Further optimization: the spiral spoiler device comprises a spiral guide plate fixedly installed inside the vertical separator tank body, and the spiral guide plate is arranged in a spiral shape along the inner surface of the vertical separator tank body.

[0009] Further optimization: the spiral guide plate is arranged at the upper position of the air inlet, and is used to give the airflow delivered from the air inlet a downward rotation direction, and to separate air and water through the action of centrifugal force and gravity.

[0010] Further optimization: the spray pipeline includes at least two spray pipes arranged at intervals, the spray pipes are fixedly installed in the vertical separator tank and located above the spiral guide plate; a plurality of spray heads arranged at intervals are fixedly installed on the spray pipes.

[0014] The present invention also provides a method for using the vertical separator self-spraying system. Based on the vertical separator self-spraying system described above, the method for using the vertical separator self-spraying system is performed in the following steps: S1. First, the air inlet of the vertical separator tank is connected to the gas-water mixture to be separated. A spray liquid is configured in the vertical separator tank according to the acid and alkali content of the gas-water mixture to be separated.

After the airflow in the tank body of the vertical separator after spraying enters the S-shaped labyrinth gas transmission channel, the water baffles can be used to perform secondary gas-water separation on the gas-water mixed gas, thereby improving the use effect.

[0017] 3. In the present invention, the spray liquid in the vertical separator tank is sucked by the filtrate pump and transported to the filter. The filter is used to filter the impurities in the spray liquid, and then it is re-transported to the spray pipe and sprayed through the spray head to realize the recycling of the spray liquid, so that the vertical separator tank has an automatic circulation spray system, which is convenient to use.

[0028] The spiral guide plate 3 is arranged above the air inlet 2, and is used to give the airflow delivered from the air inlet 2 a downward rotation direction, and then separate the air and water through the action of centrifugal force and gravity.

[0029] The spray pipeline sprays the diluent to dilute the alkaline or acidic substances in the water vapor, so as to reduce the corrosion degree of the air flow.

[0030] The spray pipeline includes at least two spray pipes 4 arranged at intervals. The spray pipes 4 are fixedly installed in the vertical separator tank 1 and are located above the spiral guide plate 3.

[0031] Both ends of the spray pipe 4 respectively penetrate the outer surface of the vertical separator tank 1, and a plugging head is fixedly installed on one end of the same side of the multiple spray pipes 4, and one end of the other side of the multiple spray pipes 4 is commonly connected to a delivery pipe 401.

Based on the vertical separator self-spraying system described above, the method for using the vertical separator self-spraying system is performed in the following steps: S1. First, the air inlet 2 of the vertical separator tank body 1 is connected to the gas-water mixture to be separated. The vertical separator tank body 1 is configured with a spray liquid according to the acid and alkali content of the gas-water mixture to be separated. The spray liquid is stored in the vertical separator tank body 1. The air outlet 5 is connected to the magnetic levitation turbine vacuum pump. The magnetic levitation turbine vacuum pump is used to suck the gas-water mixture into the vertical separator tank body 1 through the air inlet 2.

[0049] S2. After the gas-water mixed gas enters the vertical separator tank body 1, the gas flow is guided by the spiral guide plate 3 to spirally flow, and the gas-water separation is performed by the action of centrifugal force and gravity.

[0050] S3, the filtrate pump 13 is used to suck the spray liquid in the vertical separator tank body 1 and transport it to the filter 12. The filter 12 is used to filter the spray liquid. The filtered spray liquid is transported to the delivery pipe 401 through a pipeline.

[0052] S5. The airflow in the vertical separator tank body 1 that has been sprayed enters the S-shaped labyrinth gas transmission channel. At this time, the airflow hits the water baffle 11 during its flow, thereby changing the flow direction of the airflow. The remaining water in the airflow aggregates and precipitates on the outer surface of the water baffle 11, realizing secondary gas-water separation of the gas-water mixed gas, and then the airflow is discharged through the outlet 5.

[0053] With this design, the gas-water mixed gas can be separated into gas and water through the turbulence of the spiral guide plate 3, and the spray liquid sprayed by the spray pipe 4 can dilute the alkaline or acidic substances in the water vapor, effectively reducing the corrosive components in the airflow, reducing the impact on the magnetic levitation turbine vacuum pump, and increasing the service life of the magnetic levitation turbine vacuum pump.

[0054] An S-shaped labyrinth gas transmission channel is formed between the multiple water baffles 11. After the airflow in the vertical separator tank body 1 that has been sprayed enters the S-shaped labyrinth gas transmission channel, the water baffles 11 can perform secondary gas-water separation on the gas-water mixed gas, thereby improving the use effect.

[0055] The spray liquid in the vertical separator tank body 1 is sucked by the filtrate pump 13 and transported to the filter 12.
