Wire mesh gas-liquid separator capable of preventing liquid drop re-entrainment and application of wire mesh gas-liquid separator

Abstract

The invention discloses a wire mesh gas-liquid separator capable of preventing liquid drop re-entrainment and application of the wire mesh gas-liquid separator. The gas-liquid separator comprises a shell body and a drawer-type super-lyophobic wire mesh plate, wherein the drawer-type super-lyophobic wire mesh plate is inserted into the shell body and divides the shell body into a gas cavity and a gas-liquid cavity; a gas vent is formed in the top of the gas cavity; a gas-liquid inlet is formed in a side surface of the gas-liquid cavity; a liquid storage cavity is isolated by a baffle in the upper part of the gas-liquid cavity; a liquid storage tank is arranged at the bottom of the liquid storage cavity. Through the design combining wire mesh super-lyophobic treatment, buffering of the liquid drop impact of lyophilic metal foam, isolation of the liquid storage cavity, and timely guiding of a storage liquid, liquid drop re-entrainment caused by tearing of liquid films on the wire mesh and the surface of the liquid storage tank as well as splashing of the liquid drop impact can be prevented from the source, the separation efficiency of the gas-liquid separator can be greatly improved, the entrainment of outlet gas droplets can be effectively controlled, and a reliable guarantee is provided for efficient and safe production of the energy and chemical industry.

Description

technical field [0001] The invention belongs to the technical field of separation and filtration in the energy and chemical industry, and in particular relates to a wire mesh gas-liquid separator for preventing secondary carryover of liquid droplets and its application. Background technique [0002] The gas-liquid separation process is often involved in the energy and chemical industries. For example, the harmful liquid droplets in the exhaust gas of chemical factories need to be removed to reduce the impact on the environment; Steam turbine blades are safe; lubricating oil droplets need to be removed at the outlet of large air compressors to ensure the purity of the supplied gas; steam generated by flash seawater desalination needs to be separated from steam and water to reduce salinity in the prepared water, etc. [0003] At present, gas-liquid separation includes inertial force separation, centrifugal force separation, capillary force separation, etc., corresponding to co...

AI Technical Summary

Problems solved by technology

The above three aspects constitute the main source of the secondary carryover of droplets. Since the secondary droplets are much smaller than the size of the incoming droplets, the separation effect will be seriously deteriorated, which has laid a considerable hidden danger for the safety and environmental protection of energy and chemical industry.
