Abstract

The invention discloses a low concentration, large wind volume and high odor waste gas concentration energization equipment and a technology thereof and belong to the field of industrial waste gas purification.The equipment comprises a waste gas inlet, an adsorption and desorption chamber and a catalytic decomposition chamber, the equipment further comprises a heat exchanger, a heater and an internal circulation fan, wherein an adsorbing agent is arranged in the adsorption and desorption chamber, a waste gas inlet, a desorption gas outlet, an exhaust port and a desorption gas inlet are formed in the adsorption and desorption chamber, the desorption gas inlet is communicated with one end of the internal circulation fan by a pipeline, the other end of the internal circulation fan, the heat exchanger, the heater and one end of the catalytic decomposition chamber are connected sequentially, and the other end of the catalytic decomposition chamber is connected with the heat exchanger which is connected with the desorption gas outlet.Multiple stages of absorption systems are adopted, so that pollutant components with weak adsorption force can be removed more efficiently, the odor purification efficiency is improved, and multicomponent gas can reach the standard stably; the adsorption efficiency of organic waste gas is improved, and waste heat of catalytic waste gas is recycled so that the energy saving effect is remarkable.

Description

technical field [0001] The invention relates to the field of industrial waste gas purification, in particular to low-concentration, high-volume, high-odor waste gas concentration and energy conversion equipment and a process thereof. Background technique [0002] "Low concentration, large gas volume, many components, and strong odor" are the pollution characteristics of common industrial organic waste gas. With the continuous improvement of residents' requirements for surrounding air quality, more and more sewage enterprises are facing "odor complaints". At the same time, the implementation of the sewage charging system has also sounded the alarm for sewage enterprises. , must solve the problem of exhaust gas odor. However, some common organic waste gas treatment technologies, such as high-temperature incineration, absorption, plasma, photocatalytic oxidation, etc., are difficult to meet current and future environmental protection requirements due to economic, technical and...
