Problems solved by technology

Due to the poor thermal conductivity of the adsorption material itself, it is often difficult to achieve the ideal desorption effect when the heat transfer oil coil indirectly heats the adsorbent layer
Direct air desorption may be dangerous, and the presence of oxygen under certain conditions will affect the quality of recycled materials
Due to the high cost problem caused by the use of inert gas, there are not many applications of inert gas desorption in the past

Abstract

The invention relates to a method for recycling and purifying the organic from exhausted gas, and a relative device, wherein the invention uses at least two absorbers filled with adsorption agent to alternatively operate, assisted with gas decomposition adsorption, heat exchange and condense recycle techniques, to automatically continuously recycle and purify the organic. The inventive purify efficiency is higher than 90% and the recycle rate is higher than 80%.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a method and a device for absorbing, recovering and purifying organic matter from exhaust gas. Background technique [0002] In order to protect the environment and recycle resources, more and more attention has been paid to the purification and recovery of organic gases in exhaust gas. The combustion, catalytic conversion and biological purification methods in the current treatment process of gaseous organic pollutants are all pure purification processes, and cannot recover useful organic matter. In most cases, the operating cost of the process is relatively high, except for biological methods, which are usually only suitable for purification occasions with low pollutant loads. [0003] The purification and recovery of organic matter can be carried out by membrane method, absorption method, adsorption method and other methods. The membrane method n...
