Pulsation swirler with internally arranged screw rod

Abstract

Provided is a pulsation swirler with an internally arranged screw rod. The main purpose is to provide swirling separation equipment which is high in separation efficiency, small in equipment size andconvenient to operate and maintain. The pulsation swirler is characterized in that the interrupted screw rod is arranged in the center of a cyclone separator, the interrupted screw rod is of a hollowstructure and is composed of spiral sections and open hole sections in an interval distribution manner, and the spiral rotation direction of the spiral sections is opposite to the rotational flow direction after liquid enters the swirler; a backwash round tube is nested in the interrupted screw rod, open hole sections on the backwash round tube correspond to those of the interrupted screw rod, a top end opening of a hollow part of the interrupted screw rod and the backwash round tube is connected with an overflow port of the swirler, the liquid can enter the internal hollow part through the open hole sections of the screw rod and the backwash round tube, moves upwards and is discharged from the swirler through the overflow port. The swirler can effectively solve the technical problems of small density differences of two-phase media, high viscosity of separation media, low separation accuracy and the like.

Description

technical field [0001] 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. Background technique [0002] 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. [0003] It is well known that the fluid flow characteristics in...

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
