Problems solved by technology

Due to the high viscosity of the polymer-containing sewage, the oil removal efficiency of the subsidence section in the oil field surface process is low, which increases the load of the filter section, resulting in serious pollution of the filter material and deterioration of the filtered water quality
Moreover, polymers have also been seen in more and more water flooding sewage stations, causing the quality of treated water to deteriorate and it is difficult to meet the requirements of water injection

Embodiment Construction

[0033] The present invention will be further described below in conjunction with accompanying drawing:

[0034] Depend on Figure 1 to Figure 11 As shown, this kind of built-in screw rod type pulsating cyclone includes a cyclone outer cylinder, and the cyclone outer cylinder has a double tangential inlet 1, a swirl chamber 2, a large cone section 4, a small cone section 5, The conventional structures of the liner section 6 and the tangential underflow opening 7 are unique in that:

[0035]A discontinuous screw rod is built in the outer cylinder of the cyclone. The interior of the discontinuous screw rod is hollow. From top to bottom, there are overflow section 15, upper opening section 13, upper helical section 12, and middle opening. The hole section 11, the lower helical section 10 and the lower opening section 9, the opening section is smooth without spiral. Among them, between the overflow section 15 and the upper opening section 13, a first positioning round table 16 an...

Abstract

A built-in screw type pulsating cyclone. The main purpose is to provide a cyclone separation device with high separation efficiency, small device size and convenient operation and maintenance. It is characterized in that: a discontinuous screw rod is built in the center of the cyclone separator, and the discontinuous screw rod is a hollow structure, which is composed of a helical section and an opening section distributed at intervals. The direction of the swirling flow behind the device is opposite; a backwash circular tube is nested inside the intermittent screw rod, and the opening section on the backwash circular tube corresponds to the opening section of the intermittent screw rod. The top opening of the hollow part of the screw rod and the backwashing tube is connected with the overflow port of the cyclone. Through the opening section of the screw rod and the backwashing tube, the liquid can enter the inner hollow part and move upward through the overflow port. Drain the cyclone. This cyclone can effectively solve technical problems such as small density difference between two-phase media, high viscosity of separation medium and low separation precision.

Description

[0001] Technical field: [0002] The invention relates to a two-phase separation treatment device applicable to the fields of petroleum, chemical industry, environmental protection and the like, in particular to a two-phase cyclone separation device. [0003] Background technique: [0004] At present, cyclone separation technology is widely used in separation treatment in petroleum, chemical industry, municipal environmental protection and other fields. Among the existing cyclone separation technology devices, hydrocyclones are widely used. The separation principle is to use the density difference between the media to carry out centrifugal separation. The larger the density difference, the larger the particle size of the dispersed phase, and the separation effect will be greater. Relatively, the better; it has the advantages of simple structure, high separation efficiency, small equipment size, and easy operation and maintenance. [0005] It is well known that the fluid flow c...
