[0002] Oil-water separator is a kind of device, which is divided into catering oil-water separator and industrial oil-water separator. Catering oil-water separator is used to treat sewage in the catering industry. Due to environmental protection requirements, sewage discharged into rivers, lakes and seas from ships and machinery must be treated, and industrial oil-water separators are needed. When compressed air enters the oil-water separator, the flow direction and speed change sharply, and then rely on inertia to separate oil droplets and water droplets with a density greater than that of compressed air. Common ones are impact oil-water separators and circular rotary oil-water separators.

[0003] In the prior art, when an oil-water separator is used, grease usually floats on the water, and a drain pipe is set at the bottom of the separator for drainage. However, when the temperature is low, the grease is easy to condense into blocks and sink to the bottom of the water. Therefore, during the drainage process, the grease blocks are easy to block the water outlet pipe. Therefore, there is an urgent need for a water outlet device for the oil-water separator.
