Greasy dirt-resistant oil-water separator

Abstract

The invention discloses a greasy dirt-resistant oil-water separator. The greasy dirt-resistant oil-water separator comprises a tank, the top of the tank is provided with a light oil outlet and a backwashing air inlet for compressed air connection and the bottom of the tank is provided with a heavy oil discharge outlet and a sewage draining outlet. The greasy dirt-resistant oil-water separator also comprises an inlet water separator, an outlet water separator below the inlet water separator, a cylindrical oil-water separation filter core and an outlet water diversion mechanism. The inlet water separator and the outlet water separator are fixed in the tank. The side wall of the tank is provided with a water inlet and a water outlet. The water inlet and the inlet water separator are connected. The water outlet is connected to the outlet water separator. The cylindrical oil-water separation filter core is fixed to the inlet water separator and is communicated with the inlet water separator. The outlet water diversion mechanism is fixed to the bottom of the outlet water separator and is communicated with the outlet water separator. The greasy dirt-resistant oil-water separator has the advantages of small land occupation area, safety, reliability, simple processes, low operation power consumption, wide application range, good dirt blocking resistance, cleaning easiness, long service life, good oil-water separation effects and high separation efficiency.

Description

technical field [0001] The present invention relates to the technical field of oil-water separation, in particular to a kind of pollution-resistant water for oily sewage such as coal-to-oil Fischer-Tropsch synthetic water, coal gasification sewage, semi-coke sewage, oil shale sewage, oily sewage in oil fields, and oily sewage in machining. Oil-water separation device. Background technique [0002] Oily wastewater is a common industrial wastewater. With the rapid development of the national economy, the amount of oily wastewater produced by many industries such as petroleum exploration, petroleum processing, and mechanical processing is also increasing. The harm caused by oily wastewater to the environment is also increasing. The hazards of oily wastewater are mainly manifested in the following aspects: ① affects drinking water resources and groundwater resources, and endangers aquatic resources; ② endangers human health; ③ pollutes the atmosphere; ④ affects crop production;...

AI Technical Summary

Problems solved by technology

Emulsified oil is very fine oil droplets with a particle size of 0.1-10 μm. Due to the presence of surfactants at the oil-water interface, it is usually stably dispersed in water in the form of oil-in-water, and it is difficult to separate. Traditional removal of oily sewage Oil technology is not ideal for the removal of emulsified oil, and often supplemented by electrolysis, flocculation and other pre-emulsification processes, which consume a lot of energy and materials

[0004] In addition, another existing oil-water separation process is membrane (organic membrane) method, but in this operation process, it is necessary to maintain the high permeation flux of the organic membrane. Not only is the operation inconvenient, but also the separation efficiency is low, so it is not suitable for actual large-scale application
