Description

Oil-water separator

Technical Field

The utility model relates to a sanitation mechanical device field especially is applicable to the oil water separator that carries out physical treatment to oil and water in the oily sewage that the rubbish compressor extruded.

Background

With the social civilization and progress, the awareness of environmental protection and environmental quality of people is increasing day by day, and especially, the environmental quality requirements of people on living environment, urban environment and ecological conditions are higher one day than one day for people in cities with relatively dense population, economic activity and relatively developed features. Among the various environmental pollution sources, one is the oil-water sewage source for oil removal and cleaning of parts in restaurants, dining halls and industrial and mining enterprises. After the oil-water sewage flows into a municipal sewage pipe network, the oil-water sewage is fermented, smells, generates toxin and is harmful to the health of people, the urban sewage pipe network can be blocked, the smelly sewage overflows to the ground, meanwhile, the water system around the city is poisoned and polluted, the living environment of people is not facilitated, the health of people is harmed, and the survival of people is even influenced.

In order to eliminate the environmental pollution, people have long made efforts to prepare various devices for separating and treating the oil-water mixed liquid, but the devices are often low in separation precision and separation efficiency and difficult to meet the environmental protection quality requirements of people on oil-water separation at present and in the future; some devices use a buoyancy static separation method to separate and treat some oil with a specific gravity smaller than that of water, but because the separation mode of the devices adopts a gravity static separation method, the treatment time is long, namely the separation precision is low and the separation efficiency is low; in addition, these devices usually adopt a recovery method for the separated oil, which is:

A. manual scooping method;

B. electric liquid level direct scraping method;

C. electric centrifugation.

The methods can recover the floating oil on the upper layer of the liquid, but have high energy consumption, low efficiency and high labor intensity, and particularly effectively and accurately strip and collect the oil layer and the water body, so that the water content of the stripped oil is high, or the oil content of the obtained water body is very high, and the method does not meet the environmental-friendly discharge standard.

In the oil extraction production process of oil ores with high water content, the adopted oil-water separation methods include a natural settling separation method, a thermal settling separation method, a centrifugal settling separation method, a chemical demulsification separation method, an electric demulsification separation method (the separation methods include a direct-current electrostatic field electric demulsification separation method, an alternating electric field electric demulsification separation method, a high-frequency pulse electric field electric demulsification separation method, a microwave radiation electric demulsification separation method and the like), a wetting aggregation separation method, an ultrasonic separation method, a biological dehydration separation method and the like, which show that people pay attention to how to change small oil droplets into large oil droplets so as to be connected into an oil layer. The larger the oil layer is, the more beneficial the oil and water are to promote the oil layer to float under the action of the resultant force of gravity and buoyancy due to different densities, so the oil-water separation method is called as electric demulsification of any type, chemical demulsification of any type or other types, the final process of oil-water separation is also called as the natural in a gravity field to endow the oil droplets and the water droplets with the difference of the resultant force of gravity and buoyancy to separate the oil from the water, however, people misunderstand that the key of oil-water separation is demulsification, and spend a large amount of manpower, material resources and financial resources on researching how to demulsify, so that the currently obtained oil-water separation results are obtained by applying a large amount of chemical demulsifiers and consuming huge energy and money to demulsify, but the mechanism of how to utilize free earth gravity to 'strongly' pull out the oil droplets from the water body to realize the self-separation of oil and water is not devised.

The above conventional methods have great limitations in separation speed, separation efficiency, separation accuracy, separation energy consumption, and the like.

Particularly for daily frequent garbage treatment, sewage can slowly flow out after compression treatment, and the sewage contains grease. Direct discharge can seriously pollute the environment. Therefore, an oil-water separator is needed to be designed to separate the oil in the garbage sewage from the sewage and collect the oil for centralized treatment. While the sewage containing no oil is discharged from the sewage pipeline.

The existing oil-water separation methods are many, and include a physical separation method, a chemical separation method, an electric floatation separation method, a gravity separation method and the like.

Among them, gravity separation method has the advantages: the structure is simple, and the operation is convenient; however, this has the disadvantage that only free oil can be separated, but not emulsified oil.

The existing physical separation device has the defect that the traditional method can not meet the requirements in the aspects of separation speed, separation efficiency, separation precision, separation energy consumption and the like.

SUMMERY OF THE UTILITY MODEL

It is to be understood that both the foregoing general description and the following detailed description of the present disclosure are exemplary and explanatory and are intended to provide further explanation of the disclosure as claimed.

To the above problem, the utility model provides a novel oil water separator.
