The invention relates to an oil-water separating unit for an alkali degreasing production line, comprising a stock solution tank, a vacuum lifting barrel, a pump, an oil puddle collector, and a floating oil separator, wherein the inlet of the pump is connected with the vacuum lifting barrel, the vacuum lifting barrel is communicated with the stock solution tank, the outlet of the pump is respectively connected with the upper cavity and the lower cavity of the left side of the oil puddle collector through a pipeline, the upper cavity and the lower cavity of the right side of the oil puddle collector are respectively connected with the fluid inlet of the bottom of the floating oil separator through a pipeline, the clear water outlet of the lower side wall of the floating oil separator is connected with the stock solution tank, and the oil outlet of the upper portion of the floating oil separator is communicated with a waste oil barrel. According to the invention, by using the unique mode of oil absorption and arranging the oil puddle collector with self-cleaning power-up functions and the pioneering spiral separator, oil-water separation in the alkali degreasing production line can be effectively realized, and the purposes of prolonging the service life of alkali liquor, reducing waste liquid discharge and saving the production cost are achieved.
Description
technical field [0001] The invention relates to an oil-water separation device used in an alkali degreasing production line, and belongs to the technical field of oil-water separation equipment for alkali liquor. Background technique [0002] In the rolling process of metal plates, in order to lubricate between the roll and the material, it is necessary to use a large amount of rolling oil, which leads to 300-600 mg / m on one side of the rolled material surface 2 of residual oil adsorption. In the subsequent production process, there are several methods for cleaning residual oil, but the most effective and economical method is alkali cleaning, and this production line is an alkali degreasing production line. [0003] After the lye has been used for a period of time (usually 2 to 3 weeks) in the alkali degreasing production line, it must be replaced if it contains a lot of grease. Therefore, there is not only the problem of emission pollution, but also waste of solution, was...
