Referring to fig. 1, a compressor system for nitrogen and oxygen compression comprises a water-injection type single-screw compressor 1, a gas-liquid separation tank 2, and a nitrogen and oxygen storage container 3 or a conveying pipeline.
The water-injection type single screw compressor 1 has a suction port and a discharge port, and the gas-liquid separation tank 2 has a gas-liquid inlet, a first gas outlet and a second gas outlet.
The suction inlet of the water-jet single-screw compressor 1 is connected with an air inlet pipeline 4, and the air inlet pipeline 4 is used for connecting a device for conveying nitrogen and oxygen, such as a pump.

The negative pressure transmitter 5 monitors the air inflow in the air inlet pipeline 4, the pressure sensor 11 monitors the pressure in the system after the gas is compressed, the normal operation of the whole compressor system is guaranteed, and the control system can adjust the working parameters of the nitrogen and oxygen conveying device and the water-spraying single-screw compressor 1 according to the monitoring data of the negative pressure transmitter 5 and the pressure sensor 11.
When the compressor system normally works, nitrogen or oxygen enters the water-spraying single-screw compressor 1 through the air inlet pipeline 4 for compression, the negative pressure transmitter 5 monitors the air inflow in the air inlet pipeline 4 and then enters the gas-liquid separation tank 2 through the gas-liquid conveying pipeline 6 for separation, the separated compressed gas is input into the nitrogen and oxygen storage container 3 or the conveying pipeline through the minimum pressure valve 8, and the separated liquid can enter the water-spraying single-screw compressor 1 again through the liquid return pipeline (not shown in the figure) under the action of the system pressure, so that the normal lubrication and cooling of the water-spraying single-screw compressor 1 are ensured, and the operation is circulated.
When the air input is reduced, the normal work of the water-spraying single-screw compressor 1 cannot be guaranteed, and negative pressure is formed in the air inlet pipeline 4, the negative pressure transmitter 5 sends a signal, the electromagnetic valve 10 on the bypass pipeline 9 is opened, gas in the gas-liquid separation tank 2 enters the air inlet pipeline 4 through the bypass pipe and enters the water-spraying single-screw compressor 1 again for compression, so that certain system pressure is generated and kept in the water-spraying single-screw compressor 1, the normal circulation and liquid supply of a lubricating liquid path are guaranteed, and the lubricating and cooling effects are guaranteed. When the air inflow is increased and the pressure in the air inlet pipeline 4 reaches a normal value, the negative pressure transmitter 5 closes a signal, the electromagnetic valve 10 on the bypass pipeline 9 is closed, and the gas in the gas-liquid separation tank 2 does not enter the water-spraying single-screw compressor 1 any more, so that extra gas loss is avoided. The operation is circulated in such a way.
