Method and device for multi-stage gas-liquid separation

Abstract

The invention discloses a method and a device for multi-stage gas-liquid separation. The method comprises the following steps: allowing the gas in a medium to rapidly expand by passing through a conical diffusion tube; stabilizing the medium, then, subjecting the medium to multi-stage flow division, and injecting the medium onto the inner wall of an injection control tube by passing through a multi-stage dispersing tube to form a cylindrical gas-liquid column; collecting the liquid by a cylindrical body; absorbing the medium subjected to primary separation by a liquid collecting plate at the top of the cylindrical body in the rising process, so as to carry out the secondary separation; and discharging the separated gas from an outlet. By subjecting the medium to multi-stage expansion and multi-stage separation, the method of the invention is capable of conducting the complete separation of the two-phase components in the medium, thereby effectively controlling the height of the liquidlevel and achieving the effect of separation; and the invention has the characteristics of simple structure and convenient operation.

Description

technical field [0001] The invention relates to a multistage gas-liquid separation method and device, belonging to the technical field of gas-liquid separation. Background technique [0002] Gas-liquid separation technology is indispensable in many processes. At present, the commonly used gas-liquid separation methods are adsorption type, filter type, and compound type, etc. The separation device is designed according to the medium and process conditions. The types of separation devices usually include wire mesh, Packing, cyclone, baffle, etc.; screen and packing separation devices have high requirements on the separation medium, and the separation capacity is low; the cyclone has a large capacity, but the separation effect is not ideal, and the viscosity of the medium is limited; the structure of the baffle is simple, But the separation doesn't work well. Some of the above-mentioned devices are complicated in structure, which is not conducive to popularization, and some of...

[0002] Gas-liquid separation technology is indispensable in many processes. At present, the commonly used gas-liquid separation methods are adsorption type, filter type, and compound type, etc. The separation device is designed according to the medium and process conditions. The types of separation devices usually include wire mesh, Packing, cyclone, baffle, etc.; screen and packing separation devices have high requirements on the separation medium, and the separation capacity is low; the cyclone has a large capacity, but the separation effect is not ideal, and the viscosity of the medium is limited; the structure of the baffle is simple, But the separation effect is not good

Some of the above-mentioned devices are complicated in structure, which is not conducive to popularization, and some of them are expensive, which increases the investment cost of equipment

Therefore, the existing gas-liquid separation technology is still not ideal enough.
