Mist catching separation device

Abstract

The invention discloses a mist catching separation device, which comprises a pressing grid and a support frame. The pressing grid and the support frame are sequentially fixed in a tower body or a container from top to bottom; a mist catching wire mesh is arranged between the pressing grid and the support frame; the mist catching wire mesh and a plate coalescent pack are laminated between the pressing grid and the support frame; and the plate coalescent pack is positioned under the mist catching wire mesh. The mist catching separation device adopts a structure that the mist catching wire mesh is combined with the plate coalescent pack to form a liquid-mist separation component, the plate coalescent pack has strong anti-blocking so as to realize initial mist separation, and the mist subjected to the initial separation is subjected to secondary separation of the mist catching wire mesh to achieve better separation effect; therefore, the use range of the mist catching separation device is broadened, equipment corrosion is excellently reduced, service life is prolonged, treatment capacity is improved, valuable materials are recycled, environment is protected, atmospheric pollution is lightened and the like.

Description

technical field [0001] The invention relates to a gas-liquid separation device, in particular to a foam catcher and separation device. Background technique [0002] In the process of chemical process production, various gas two-phase contact often entrains a lot of liquid droplets, and it is generally required to separate the gas liquid droplets so as not to affect the gas quality or the operation of the next process. Foam catcher is a filter device for liquid foam in gaseous fluids. It is widely used in chemical industry, petroleum, sulfuric acid, medicine, light industry, metallurgy, aerospace, shipbuilding, environmental protection and other industries. It can be installed at the inlet and outlet of gas compressors. For gas-liquid separation, it can be installed on the top of the fractionation tower for gas-phase demisting after the condensing cooler, and can be used for gas-phase demisting of various gas washing towers, absorption towers and analytical towers, etc. The ...

AI Technical Summary

Problems solved by technology

The existing wire mesh foam catcher has the following disadvantages: 1) It is easy to block, and it needs to be cleaned frequently, which affects the long-term efficient operation of the evaporation equipment; 2) The vapor-liquid separation effect is poor, and it is easy to cause part of the material liquid to escape, which is not conducive to recovery and affects the process yield.
