Problems solved by technology
[0002] At present, the equipment for treating industrial wastewater or sewage generally does not have a distilled water degreasing device or is equipped with a simple and inefficient degreasing device. The discharged distilled water cannot meet the discharge standard due to high oil content.
[0003] During the research and practice of this method, the inventors of the present invention found that the separation effect of the traditional oil-water separator is not obvious and requires a large space

Embodiment
[0029] Such as Figure 1 to Figure 4 , an oil-water separation device for metal cutting fluid treatment, which includes a separation unit, a discharge unit and a heating unit, the separation unit is used to separate the oil, water and gas in the oil-water mixture after passing through the evaporator, and the separation unit It includes a separator body 1, a separator cover 6, a partition 14 and a water inlet 11. The separator body 1 is a hollow barrel-shaped structure, and the upper part of the separator body 1 is sealed with a separator cover 6. The upper part of the wall of the separator body 1 is provided with a water inlet 11, and a partition 14 is vertically placed inside the separator body 1, and the condensed oil-containing water-air mixture (95% is condensed water) enters the separator through the water inlet 11 In the body 1, both sides of the separator 14 are respectively connected to the inner wall of the separator body 1, and the separator 14 is used to change the ...

The invention relates to an oily water separating device for processing metal cutting liquid. The device comprises a separating unit, a discharging unit and a heating unit, wherein the upper part of a separator body is connected with a separator cover in a sealing manner; water inlets are distributed in the upper part of the wall of the separator body; a partition plate is vertically arranged in the separator body; an oil sucking pipe is mounted on the separator cover; a first draining opening is formed in the upper part of the wall opposite to the water inlets; a heater is mounted in the separator body, and is positioned on one side of the partition plate. The invention has the following benefits: the oily water separating device achieves effective separation of oil, water and gas through the cooperation among the separating unit, the discharging unit and the heating unit; the electric heater can provide continuous heat sources, so that a stock solution achieves the evaporation temperature in a short time, and the temperature compensation is provided in the subsequent operation; in the operation process of the device, the heat in steam is absorbed by feed liquid, so that the energy loss is reduced, and the environmental friendliness is achieved.
Description
technical field [0001] The invention relates to the technical field of metal cutting fluid treatment, in particular to an oil-water separation device for metal cutting fluid treatment. Background technique [0002] At present, the equipment for treating industrial wastewater or sewage generally does not have a distilled water degreasing device or is equipped with a simple and inefficient degreasing device, and the discharged distilled water cannot meet the discharge standard due to high oil content. [0003] During the research and practice of this method, the inventors of the present invention found that the separation effect of the traditional oil-water separator is not obvious and requires a large space. [0004] At present, the main method of treating industrial wastewater or sewage equipment is low-temperature evaporation. The main principle is as follows: figure 1 As shown, the pressure inside the evaporator 7 and the separator 9 is reduced by the compressor 8, and th...
