Technical Field
[0001] The utility model relates to the technical field of industrial wastewater treatment, in particular to an oil-water separation structure for distilled water in an MVR vacuum distillation system. Background Art
[0002] An MVR vacuum distillation system is used to treat oily wastewater. An evaporation tank is provided in the MVR vacuum distillation system, and the distilled water generated by the evaporation tank needs to be discharged. After the industrial oily wastewater is evaporated, the distilled water contains oil, resulting in an oil-water mixing phenomenon, which leads to poor discharged water quality and environmental pollution. Therefore, it is necessary to re-filter the discharged distilled water. Summary of the Utility Model
[0003] Based on this, in view of the problem that the distilled water discharged from the evaporation tank contains oil, an oil-water separation structure for distilled water in an MVR vacuum distillation system is provided.
[0004] To achieve the above object, the utility model provides the following technical solution: an oil-water separation structure for distilled water in a vacuum distillation system, including a distilled water tank body, an inlet pipeline and an outlet pipeline are provided on the side wall of the distilled water tank body, and the inlet pipeline is communicated with the evaporation tank.
[0005] An oil suction pipe, the oil suction pipe is arranged on the top of the distilled water tank body, and one end is communicated with the inside of the distilled water tank body, and the other end is communicated with the evaporation tank through a pump.
[0006] A buffer plate, the buffer plate is placed at the port of the inlet pipeline inside the distilled water tank body, and covers the periphery and the top of the port of the inlet pipeline to form a buffer cavity.
[0007] The outlet pipeline is communicated with the inside of the distilled water tank body, extends to the bottom of the distilled water tank body, and does not contact the bottom surface of the distilled water tank body.
[0008] In a preferred example of the utility model, it can be further configured that: an air inlet pipe is further provided on the top of the distilled water tank body for the air above to communicate with the upper part of the tank body during liquid discharge.
[0009] By adopting the above technical solution, the oil suction pipe is communicated with the top of the evaporation tank through a pump, and the oil at the top of the distilled water tank body is pumped back to the evaporation tank for evaporation again.
[0010] In a preferred example of the utility model, it can be further configured that: a cooling device is provided between the inlet pipeline and the evaporation tank.
[0011] By adopting the above technical solution, the cooling device quickly cools the distilled water. The purpose is to precipitate and float the oil in the water after quickly cooling the water, which is convenient for subsequent oil pumping.
[0012] In summary, the utility model includes at least one of the following beneficial technical effects:
[0013] After being cooled, the distilled water is discharged into the distilled water tank through the inlet pipeline. After the distilled water is rapidly cooled, the oil in the water will precipitate and float, and is pumped back to the evaporation box through the oil pumping pipeline to form a reflux and re-evaporation, reducing the oil content in the discharged distilled water;
[0014] By setting a buffer plate, the just-discharged distilled water is buffered to prevent the large flow rate of the distilled water inside the distilled water tank from causing oil-water mixing. Brief Description of the Drawings

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0021] In Figure 1-2 the shown embodiment, the present invention provides a technical solution: a vacuum distillation system distilled water oil-water separation structure, including a distilled water tank 1, an inlet pipeline 13 and an outlet pipeline 14 are provided on the side wall of the distilled water tank 1, and the inlet pipeline 13 communicates with the distilled water outlet of the evaporation box.
[0022] A cooling device is provided between the inlet pipeline 13 and the evaporation box. The cooling device includes a cold water coil for cooling the distilled water, and the distilled water is cooled after passing through the coil. The outlet pipeline 14 communicates with the inside of the distilled water tank 1, extends to the bottom of the distilled water tank 1, and does not contact the bottom surface of the distilled water tank 1.
[0023] At the top of the distilled water tank body 1, there are an oil extraction pipe 11 and an air inlet pipe 12. The air inlet pipe 12 is connected to the top of the buffer cavity, and the oil extraction pipe 11 is connected to the cavity outside the buffer cavity. One end of the oil extraction pipe 11 is connected to the inside of the distilled water tank body 1, and the other end of the oil extraction pipe is connected to the evaporation tank through a pump. The air inlet pipe 12 is used to make the air above communicate with the upper part of the tank when discharging liquid, which is convenient for discharging distilled water.
[0024] The buffer plate 2 is placed at the port of the inlet pipeline 13 inside the distilled water tank body 1 and covers the periphery and top of the port of the inlet pipeline 13 to form a buffer cavity. The bottom of the buffer plate 2 only needs to be placed below the port of the inlet pipeline 13 and should not be too low.
[0025] The specific working principle of the present invention will be elaborated in detail below: The distilled water flows out from the evaporation tank, is cooled by the cooling device, and then enters the inside of the distilled water tank body 1 through the inlet pipeline 13. The distilled water first enters the buffer plate 2 for rectification. After entering the distilled water tank body 1, the oil floats up, and the oil is pumped into the evaporation tank through the oil extraction pipe 11 and the pump for evaporation again. The water at the bottom of the distilled water tank body 1 is discharged through the outlet pipeline 14 by the pump, reducing the oil content in the discharged distilled water.
