Three-phase cyclone separator cleaning treatment system for oil-contaminated water

Abstract

The invention relates to a treatment technique for purifying oil-polluted water. The invention provides a three-phase cyclone separator and a purification treatment system containing the three-phase cyclone separator for simplifying the purification process of oil-polluted water. The three-phase cyclone separator comprises a conical sludge collector at the lower part, a cyclone sedimentation area at the upper part, a sloped tube sedimentation area and a filter layer area, wherein a plurality of oil capturing plates are arranged between the sloped tube sedimentation area and the filter layer for forming an oil capturing area, the oil capturing plates are provided with conically raised oil-collecting cones which are evenly distributed, and a top oil collecting hole on the uppermost oil capturing plate is communicated to a cavity body provided with an oil outlet at the top part of a tank body through an oil pipe. The oil-polluted water purification treatment system including the three-phase cyclone separator comprises a medicament treatment and launching section, the three-phase cyclone separator and an oxidation and filtration adsorption section. The treatment technique has advantages of short technical process, less time consuming in the purification treatment, small occupying area, stable water treatment, recyclable oil resource, environmental protection and reaching the standards.

Description

technical field [0001] The invention relates to a purification treatment system for oily sewage and a multi-phase sewage separation device. Background technique [0002] During the operation of land and offshore oil and natural gas exploitation, countless oily sewage is produced, mainly including oil production sewage, drilling and well washing sewage, among which oil production sewage has the largest amount, which has high oil concentration and contains a large amount of suspended solids and sulfides , COD and other pollutants. How to deal with these oily sewage, separate the oil, especially in the purification of COD, make it meet the environmental protection discharge standards, and also meet the requirements of water resource reinjection and reuse. This is not only applicable to the economic development requirements of the petroleum industry, but also to maintain the original ecology of the earth. , Relieve the huge pressure on environmental protection, and enhance the ...

AI Technical Summary

Problems solved by technology

To sum up, the common technical problems of the existing oily sewage technology are: long sewage treatment process, huge system, large equipment footprint, high equipment cost, poor water purification effect, and inability to adapt to decentralized, small sewage volume. , Well-washing wastewater with serious pollution, especially the treatment requirements of well-washing wastewater in production
