Oily water vacuum separating device

Abstract

The invention discloses an oily water vacuum separating device which comprises an oil-water preseparator, an oil-water separator, a vacuum evaporator, a vacuum pump and a guiding device. A water draining port of the oil-water preseparator is communicated with an input port of the oil-water separator, an oil discharging port of the oil-water preseparator and an oil draining port of the oil-water separator are communicated with an input port of the vacuum evaporator, and an air exhausting port of the oil-water preseparator, an air exhausting port of the oil-water separator and an air exhausting port of the vacuum pump are communicated with the vacuum pump. A cylindrical filter element is built in the oil-water separator, and the guiding device comprises a guiding portion arranged in the same angle direction and is assembled inside the top of the filter element. The oily water vacuum separating device performs oil-water separation under vacuum conditions, the guiding device conducts flow guiding on oily water flowing towards the filter element and meanwhile conducts oil-water preseparation on oily water again, oily water drops gathered on the filter element are removed in time, the filtering load of the filter element is reduced, and improvement of the separation effect and the separation efficiency of the separating device is promoted.

Description

Technical field [0001] The invention relates to a sewage oil-water separation device, in particular to a sewage oil-water vacuum separation device that guides the flow direction of the sewage oil and water to be treated and performs oil-water separation under vacuum conditions, and belongs to the field of sewage treatment. Background technique [0002] With the rapid development of society and the substantial improvement of people's quality of life, people produce a large amount of oily sewage in daily life activities, such as domestic sewage generated in daily life activities, especially large amounts of catering sewage generated by the catering industry; The sewage produced by the ships that people travel and ride on contains a large amount of slop oil. The direct discharge of oily sewage will inevitably cause pollution to the river or the sea, and affect the normal growth of river organisms or marine organisms. The country and the International Maritime Organization have put ...

AI Technical Summary

Problems solved by technology

Therefore, ships and catering industries are equipped with sewage oil-water separation devices, but many problems are still exposed in the process of use: on the one hand, the sewage oil-water separation devices perform oil-water separation treatment on the sewage oil and water to be treated under normal pressure, and the separation effect is not good. On the other hand, when the sewage oil and water to be treated flow into the filter element, the flow direction is disordered, which is not conducive to the timely floating of the oil collected on the filter element; therefore, the separation effect of oil and water is not good, often requires multiple cycles of treatment, and the treatment efficiency is low
