Problems solved by technology

However, when the industrial flue gas is directly passed into the microbial energy conversion system for flue gas treatment, the high concentration of complex gas components in the flue gas (mainly acid gas components, such as CO 2 , SO 2 , NO x etc.) will cause strong poisonous effect on microbial cells and make them unable to grow, which greatly limits the efficiency of flue gas treatment and energy recovery efficiency

Abstract

The invention relates to the field of resource recovery, particularly to a flue gas treatment and resource recovery system. The flue gas treatment and resource recovery system is composed of one or more flue gas recovery units which are connected in series; every flue gas recovery unit comprises an alkaline absorbing chamber and a microorganism absorbing chamber which are separated by an anion-exchange membrane, alkaline absorbing agent is filled inside the alkaline absorbing chamber, the lower portion or the bottom of the alkaline absorbing chamber is provided with a flue gas inlet, the top or the upper portion of the alkaline absorbing chamber is provided with a flue gas outlet, the microorganism absorbing chamber is made of transparent materials and filled with microorganism culture solution, microorganisms are inoculated into the microorganism culture solution, and the microorganism absorbing chamber is provided with a microorganism culture solution inlet. The flue gas treatment and resource recovery system can absorb and utilize carbon dioxide, sulfur dioxide and nitrogen oxide in flue gas for immobilization to produce biological oil and the like and meanwhile maintain efficient growth of contained microorganisms.

Description

technical field [0001] The invention relates to the field of resource recovery, in particular to a system for flue gas treatment and resource recovery. Background technique [0002] With the acceleration of urbanization and the expansion of urban population, environmental pollution has become a major problem facing the development of human society, especially the pollution of the atmospheric environment has seriously affected human life. At present, my country's air pollution mainly comes from industrial emissions. The latest data show that from 2000 to 2011, the average annual growth rate of China's industrial waste gas emissions was 19.06%, from 13.8145 billion standard cubic meters in 2000 to 67.4509 billion standard Cubic meters, an increase of 2.39 times in 11 years. Industrial flue gas contains a lot of SO x , NO x , CO 2 Such acidic gas components, after being discharged into the air without treatment, will cause environmental problems such as acid rain, smog, and ...
