Gas-liquid separator

Abstract

The invention discloses a gas-liquid separator. The gas-liquid separator comprises a barrel, an upper head, a lower head, a silk screen device and a structured packing device, wherein a gas-liquid mixture inlet is arranged on the side surface of the lower end of the barrel; the upper head is connected to the upper end of the barrel, and a gas phase outlet is arranged at the top end; the lower headis connected to the lower end of the barrel, and a raffinate outlet is arranged at the bottom end; the silk screen device is connected between the upper head and the barrel; the structured packing device is detachably connected to the middle of the barrel; the silk screen device and the structured packing device are both made of a modified PTFE (polytetrafluoroethylene) material which is 1-2 mm thick; the modified PTFE material comprises components in percentage by mass as follows: 85% of PTFE fine powder, 12% of carbon fiber powder and 3% of graphite. The gas-liquid separator has the benefits of corrosion resistance, high temperature resistance and high separation efficiency.

Description

technical field [0001] The invention relates to the field of gas-liquid separation, and more specifically, the invention relates to a gas-liquid separator. Background technique [0002] Gas-liquid separation is a basic chemical process in petrochemical and other industries, which can realize the recovery of materials and the purification of target substances. The basic separation methods include gravity sedimentation, collision separation, centrifugal separation, Venturi gas-liquid separation, electric power Sedimentation, etc., are applicable to different particle size ranges; using different separation principles, the performance and structure of gas-liquid separators are also quite different, including split-free inertial separators, wire mesh gas-liquid separators, and separation tanks Separator, two-phase turbine separator, gravity sedimentation separator, parallel coil separator, cyclone separator, centrifugal separator and spiral separator, foam breaking net and high-...

AI Technical Summary

Problems solved by technology

[0003] At present, the lining of separator equipment is mainly made of metal stainless steel or plastic. In the process of separation and application in petrochemical and other industries, it often contains strong acid and strong alkaline substances. These strong acids and alkalis will cause corrosion to the lining of the separator. , the current solution is generally based on prevention, which is to take the "blocking" method to prevent corrosion. However, it is often difficult to solve the problem with a single anti-corrosion measure, especially for media with complicated corrosion reasons. Even if multiple anti-corrosion measures are used Measures are also difficult to solve the problem of corrosion
