Problems solved by technology

When the density difference between oil and water is small, the difference in the centrifugal force generated by the oil phase and the water phase in the cyclone is not large, making it difficult to separate oil and water; in addition, as the amount of treated liquid increases, the shear force generated by the rotation is too large, and the oil droplets Easy to break into smaller tiny droplets, thus reducing the efficiency of oil-water separation

example 1

[0033] Using metals such as iron or aluminum as the anode, under the action of direct current, the anode is eroded to produce ions such as Al and Fe. After a series of hydrolysis, polymerization and oxidation of ferrous iron, the colloidal impurities and suspended impurities in the water Condensation and precipitation are discharged through the sewage outlet 15; in addition, the oxygen and hydrogen bubbles generated by the electrolysis of water collide with and adhere to the oil droplets that rotate with the fluid in the cyclone during the floating process, forming oil droplets and air bubbles The polymer is discharged from the overflow port 7; the treated water is discharged through the No. 1 water outlet 14.

[0034] The guide tube 3 is connected to the bottom of the tail pipe section 12, and the outside is connected to the water collection chamber 4. The depth of the guide tube 3 inserted is 1 / 4 of the length of the tail pipe section 12. High aqueous drainage for further pr...

Abstract

The invention provides a high-efficiency cyclone oil-water separation device. The high-efficiency cyclone oil-water separation device includes a cyclone (1), an electrode (2), a guide tube (3), a water collection chamber (4), and a control valve. (5), membrane separation chamber (6); said cyclone (1) is a biconical hydrocyclone, and each part of the cyclone (1) from top to bottom is an overflow port (7), Inlet (8), cylindrical section (9), large cone section (10), small cone section (11), hand hole (12), tailpipe section (13), and No. 1 water outlet (14) is provided on the tailpipe section (13) ) and the blowdown outlet (15), the blowdown outlet (15) is positioned at the bottom of the tailpipe section (13). The present invention has the characteristics of simple and reasonable structural design, convenient operation, and good separation performance. The separation efficiency of the cyclone.

Description

technical field [0001] The invention relates to the technical field of oil-water separation, in particular to a high-efficiency cyclone oil-water separation device. Background technique [0002] With the increasing scale of oilfield exploitation, most of my country's oilfields have entered the middle and late stages of exploitation, and the water content in the produced fluid has also increased significantly, some reaching more than 90%. Adding some surfactants will seriously emulsify the oil droplets, which increases the difficulty of oil-water separation, which makes it difficult for the conventional oil-water separation method to make the produced water meet the discharge standard. [0003] The hydrocyclone is a common oil-water separation device. It uses the centrifugal force produced by the rapid rotation of the fluid in the swirl chamber to make the denser water phase flow to the outside, and the less dense oil droplets move to the inner ring, and gradually Through col...
