The gas-liquid separation chamber 12 is internally provided with a gas-liquid cooler 2, and the oil storage chamber 13 is internally provided with a lubricating oil cooler 3.
In order to reflux the liquid collected in the gas-liquid separation cavity 12 into the compressor for recycling, the purpose of reducing the use cost of the screw air compressor is achieved. A liquid spraying return pipe 14 communicated with the lower side of the gas-liquid separation cavity 12 is fixedly arranged on the lower side of the shell 1, and the liquid spraying return pipe 14 is in sealing connection with the shell 1.
At the same time, in order to reduce the reflux of liquid into the gas-liquid cooler 2 via the gas-liquid mixture outlet pipe 22. The shell 1 is provided with a liquid level transmitter 15, and the liquid level transmitter 15 is positioned on one side of the shell 1 where the gas-liquid separation cavity 12 is positioned. The shell 1 is also provided with a liquid outlet positioned at the lower side of the gas-liquid separation cavity 12, and the liquid outlet is provided with an electromagnetic valve 16.
In practical use, the liquid level in the gas-liquid separation cavity 12 is monitored by the liquid level transmitter 15, and when the liquid level exceeds a set value, the electromagnetic valve 16 is opened to drain.
Specifically, the gas-liquid cooler 2 is provided with a gas-liquid mixture input pipe 21 and a gas-liquid mixture output pipe 22, and the gas-liquid mixture input pipe 21 extends out of the gas-liquid separation chamber 12 through the upper side of the housing 1; the gas-liquid mixture output pipe 22 is located on the upper side of the gas-liquid cooler 2 near the partition plate 11, and the outlet of the gas-liquid mixture output pipe 22 is disposed toward the partition plate 11.
