The pumping type centrifugation oil-water separator disclosed by the invention is reliable in technique and low in manufacturing cost, required raw materials are mature and reliable, and the pumping type centrifugation oil-water separator can realize mass production, can realize continuous operation, and is high in efficiency, safe, reliable, low in hydraulic loss, notable in energy-saving effect, and obvious in economic and social benefits.

Description

technical field [0001] The invention relates to a continuously working centrifugal oil-water separator, which is used in various occasions that need to separate water-oil mixture, or other mixed fluids produced by media with different densities. Background technique [0002] Oil-water separators are widely used in modern society, mainly used in fields such as oil exploitation, catering sewage and ship sewage, to separate oil from oil-water mixture, reduce the water content in the oil to process the oil, or reduce the oil content in the water To meet the national sewage discharge standards. [0003] At present, there are three main types of common oil-water separators: static oil-water separator, the main body is one or more static separation chambers in the tank, and can be equipped with pumps, ultrasonic waves, heaters, adsorption devices, oil content detectors and other instrumentation equipment according to needs , typical products include crude oil separation tank, cate...

AI Technical Summary

Problems solved by technology

However, with the development of society, various resources, especially water resources, are becoming more and more scarce, the pressure of environmental protection is increasing, and the water content of crude oil in oil extraction is increasing. People put forward higher requirements for oil-water separators. Many shortcomings are exposed: large volume, low operating efficiency, high energy consumption, etc.:

[0004] 1. The volume is large, and the static oil-water separator requires a large tank; the main component of the cyclone oil-water separator is the cyclone cylinder, which is small in volume, but it requires external power and complex piping systems, and the total volume is large; The drum of the centrifugal extractor is also very large

[0005] 2. The operating efficiency is low. The static oil-water separator needs the medium to stay in the tank for a long time; the centrifugal extractor has always been small

[0006] 3. The energy consumption is high. The static oil-water separator needs an external pump to transport the medium; the cyclone oil-water separator needs a large external power to obtain high-flow liquid; the drum of the centrifugal extractor needs a large power to drive

[0007] 4. The maintenance workload is heavy, and the cyclone cylinder of the cyclone oil-water separator wears quickly; the structure of the centrifugal extractor is complex, the inner cavity may contain air, there are many wearing parts such as seals and bearings, and the operation is cumbersome

[0008] 5. There are certain requirements for the working medium. Certain types of cyclone oil-water separators and centrifugal extractors have requirements for the composition ratio of the oil-water mixture. If the concentration is too high or too small, the separation effect will drop sharply
