The terms "first," "second," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance. The fixed connection mode comprises but is not limited to a connection mode known in the prior art, such as welding, screwing, clamping, interference fit, integral forming and the like; the number of the plurality is more than one.
Fig. 1 shows an embodiment of the present invention. The embodiment provides a device for separating oil from gas in exhaust gas, which comprises a water tank 7, wherein the water tank 7 is divided into a first partition section 12, a second partition section 14 and a third partition section 16 by a first partition plate 13 and a second partition plate 15. As shown in fig. 1, the first partition plate 13 is arranged on the right side of the second partition plate 15, wherein the bottom of the first partition plate 13 is fixedly connected with the bottom wall of the water tank 7, and a gap is reserved between the top of the first partition plate 13 and the top wall of the water tank 7; the top of the second partition plate 15 is fixedly connected with the top wall of the water tank 7, and a gap is reserved between the bottom of the second partition plate and the bottom of the water tank 7; that is, the tops of the first partition 12 and the second partition 14 are communicated with each other, the bottoms of the second partition 14 and the third partition 16 are communicated with each other, and the second partition 14 and the third partition 16 are filled with cooling water, so that the water level cannot be higher than the first partition 13.
In the tank 7 there is thus mounted a first level gauge 8 and on the left a second level gauge 17, i.e. the first level gauge 8 is in communication with the first compartment 12 and the second level gauge 17 is in communication with the third compartment 16 for monitoring the level of the cooling water. The bottom of the first partition 12 is connected with a dirty oil tank 9 through a dirty oil pipe 11, and a valve 10 is further mounted on the dirty oil pipe 11. The air outlet 9 of the water tank 7 is positioned above the second partition section 14 and is provided with the first foam net 5, and the air outlet is connected with a torch through a pipeline.
A vacuum pump 3 and a cooler 18 are also included, the input end of the vacuum pump 3 is connected with the outlet of the tower top reflux tank through a first waste gas pipeline 2, the output end of the vacuum pump 3 is communicated with the second partition 14 of the water tank 7 through a second waste gas pipeline 4, and the free end of the second waste gas pipeline 4 is positioned below the liquid level of the cooling water. A second foam net 19 is installed at the outlet of the top reflux tank.
The third partition 16 is sequentially connected with a cooler 18 and a vacuum pump 3 through pipelines, the vacuum pump 3 is connected with the third partition 16 through pipelines, namely the vacuum pump 3 is a circulating water vacuum pump, cooling water enters the pump from a water inlet of the vacuum pump 3 after passing through the cooler 18 and then returns to the third partition 16 through a water outlet of the vacuum pump 3.
When the device is used, the vacuum pump 3 sends the waste into the second partition 14 for cooling, light oil is condensed into liquid in the process and floats on a cold water surface layer of the second partition 14, and when the thickness of the light oil exceeds the first partition 13, the liquid overflows into the first partition 12 and enters the dirty oil tank 9 through the dirty oil pipe 11; the cooling water is recycled among the vacuum pump 3, the cooler 18 and the water tank 7, and the second partition plate 15 can prevent light oil from polluting the water for the vacuum pump 3; the foam net is used for separating light oil brought by waste, and the purpose of completely separating oil and gas is achieved. The level of light oil in the first compartment 12 can be adjusted by adjusting the valve 10.
