Petrochemical oil-water efficient separation device

Abstract

The invention relates to the related technical field of petroleum, and discloses a petrochemical industry oil-water efficient separation device which comprises a separation tank body, a filter screen piece is installed in the separation tank body, an installation ring is installed in the separation tank body in a sliding mode, a sealing pressure plate is rotatably installed in the installation ring, and communication valves are arranged on the sealing pressure plate in an array mode. Stirring and rotating pieces are installed on the lower side of the sealing pressure applying plate in an array mode, a conical separating and filtering device is installed in the separating tank body, the conical separating and filtering device comprises a fixing ring groove, and a conical body is rotatably installed in the fixing ring groove; according to the high-efficiency oil-water separation device for the petrochemical industry, through setting of a high-efficiency separation function, oily wastewater is introduced into the separation tank body, the rotating motor is kept in a starting state, the rotating shaft and the transmission shaft are driven to rotate, and large-particle impurities in oil water are filtered out through the filter screen in the oil-containing wastewater introduction process.

Description

technical field [0001] The invention relates to the technical field of petroleum, in particular to a high-efficiency separation device for oil and water in petrochemical industry. Background technique [0002] In the petrochemical industry, there is a large amount of oily wastewater. In the process of treating oily wastewater, oil and water need to be separated and separated. The usual separation methods are static stratification and membrane separation. [0003] CN106430665A discloses a high-efficiency oil-water separation device, including a pretreatment chamber, an oil-water separation chamber, a conical cyclone separator, and an oil collecting chamber. The upper end of the pretreatment chamber is equipped with a water inlet pipe, and the pretreatment chamber passes through the bottom end. The first pipeline is connected to the water pump, the water pump is connected to the lower left end of the oil-water separation chamber through the second pipeline, the upper left end ...

AI Technical Summary

Problems solved by technology

[0007] In the prior art method, the separation efficiency of oil and water is relatively slow, and at the same time, the influence of oil and water impurities is likely to cause the problem of a decline in separation efficiency and effect. At the same time, the method of membrane separation is used when oil and water are in a mixed state, which can easily make efficient and effective separation operations
