Organic waste gas adsorptive recovery system and adsorption-desorption method thereof

Abstract

The invention provides an organic waste gas adsorptive recovery system and an adsorption-desorption method thereof specific to the problems of difficulty in filling powdery adsorbents, difficulty in realizing continuous adsorption-desorption operation, low adsorption efficiency, high energy consumption and the like in the conventional organic waste adsorptive recovery system. The recovery system comprises an adsorption tower, desorption equipment, automatic control equipment, condensing recovery equipment, adsorbent conveying equipment and a data treating and gas analyzing workstation. The non-enclosed desorption equipment is designed particularly, so that influent powdery rich adsorbents can be desorbed and regenerated through a 'microwave and vacuum' integration process, and desorbed oil gas is further condensed and recovered. Parameters such as temperatures and concentrations are analyzed online through the automatic control equipment and the data treating and gas analyzing workstation, so that the conveying, desorbing and regenerating operation of the adsorbents can be realized automatically. By adopting the system and the method, continuous adsorption as well as efficient desorption and regeneration of the powdery adsorbents can be realized.

Description

technical field [0001] The invention belongs to the technical field of organic waste gas recovery, and relates to a novel and efficient organic waste gas adsorption and recovery system, in particular to a high-efficiency desorption method integrating "microwave and vacuum". Background technique [0002] As the main gaseous pollutant, organic waste gas directly harms our living environment and is also one of the main causes of photochemical smog in cities. Nowadays, relevant state departments are paying more and more attention to the treatment of organic waste gas, and combine it with clean production, resource utilization, and standard discharge as an important environmental protection work of circular economy. Organic waste gas recovery technology will produce significant benefits in terms of production safety, environmental safety, and human protection. Furthermore, if the organic waste gas is recovered and converted into oil, it can be reused as energy. Therefore, the r...
