[0022] The industrial circulating water system of the prior art includes a circulating water pump, a heat exchange device, a cooling tower 5 and a circulating return pipe. Driven by the circulating water pump, water is circulated and cooled through the circulating pipeline. Other accompanying pipes and functions are not described in detail here.

[0023] Among them, there are multiple baffles 4, and the multiple baffles 4 are arranged at intervals in the horizontal direction. The upper ends of the baffles 4 are fixedly connected to the top of the shell 2. There are three baffles 4. Among the three baffles 4, the baffle 4 close to the oil baffle 3 is the first baffle 4, and the other two are the second baffles 4. The second baffle 4 is evenly distributed with multiple air flow holes. By setting the air flow holes, the speed of the oil and gas mixture is slowed down after passing through the air flow holes. Under the action of gravity, the oil in the oil and gas mixture falls, and the gas flows to the outlet 23, thereby better realizing the oil and gas separation.

[0024] Specifically, the oil outlet 23 is arranged at the bottom of the housing 2 , and a booster pump 62 and a one-way valve 63 are also arranged on the oil outlet pipe 6 .

[0025] More specifically, the air outlet 24 is arranged at the upper end of the shell 2, and the air outlet 24 is connected to the air outlet pipe 8, and the air outlet pipe 8 is provided with a fourth switch valve 81. A transparent observation window 25 facing the upper end of the oil baffle plate 3 is provided on one side of the shell 2, and the upper end of the transparent observation window 25 is flush with the upper end of the oil baffle plate 3.

[0026] In addition, two bases 26 are provided at the lower end of the shell 2 and a pressure gauge 9 is provided at the upper end of the shell 2 .

[0027] When the present application is used, the liquid in the circulating water return pipe 1 enters the sedimentation chamber 27 through the liquid inlet pipe 5, so that the upper end surface of the liquid is within the visible range of the transparent observation window 25 and lower than the upper end of the oil baffle plate 3, and then the first switch valve 51 is closed, and the oil-water separation status of the sedimentation chamber 27 is observed through the transparent observation window 25. When the oil layer in the sedimentation chamber 27 is above the water layer, the first switch valve 51 is then opened to allow the liquid to continue to enter the sedimentation chamber 27, so that the oil in the oil layer above the water layer turns over the oil baffle plate 3 and enters the oil chamber 28, and then the first switch valve 51 is closed, and the second switch valve 61 is opened to discharge the liquid in the sedimentation chamber 27.

[0028] When the liquid enters the sedimentation chamber 27, the gas present in the liquid will be discharged through the exhaust port through the sedimentation chamber 27 and the oil chamber 28 in turn, thereby realizing the separation of oil, gas and water. The above process can be cyclically carried out to separate the oil and gas in the circulating return water pipe 1, effectively preventing the safety and environmental problems caused by the leakage of oil and gas into the circulating water, and effectively avoiding the occurrence of safety and environmental accidents.

[0029] The present application sets a separator and utilizes the characteristics that the density of oil and gas is lower than that of water and oil and gas is not easily soluble in water, so as to separate the gas, oil and water into layers. The oil flows over the oil baffle 3 into the oil chamber 28 and is discharged through the oil outlet 23, and the gas is discharged through the gas outlet 34, thereby preventing oil and gas from entering the circulating water field and reducing the safety risks of operators.

Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model fall within the protection scope of the present utility model.
