Therefore, the utility model realizes the recycling of energy, and has obvious energy saving effect. A tapered housing 13 is mounted on both sides of the adsorption wheel 11, and the two ends of the housing are respectively connected to the exhaust gas inlet pipe 20 and the purge gas exhaust pipe 1 31 (see Figs. 1, 2).
本实用新型在工作时， 将工业有机废气经有机废气输入管 20送入吸附 轮 11， 经过吸附轮后， 有机废物被吸附到活性纤维片 115上， 使废气得到 净化， 分离后的洁净空气用出口风机由净化气排气管 1 31 排出。 由于吸附 轮经一定时间的吸附后会达到饱和， 因此需对吸附到吸附轮的有机废物进 行解吸， 解吸是将小风量热风送入吸附轮进行加热蒸发， 使得催化燃烧后 的废气成为解吸的热源。 解吸后的高浓度废气通过解吸循环风机 30送入催 化净化炉 40进行催化燃烧（即低温氧化）， 催化燃烧后排出的热风经管道 送到吸附轮 11的解吸区 11B供解吸用。  When the utility model is in operation, the industrial organic waste gas is sent to the adsorption wheel 11 through the organic waste gas input pipe 20, and after passing through the adsorption wheel, the organic waste is adsorbed onto the active fiber sheet 115 to purify the exhaust gas, and the clean air after separation is used. The outlet fan is exhausted by the purge gas exhaust pipe 1 31. Since the adsorption wheel will reach saturation after a certain period of adsorption, the organic waste adsorbed to the adsorption wheel needs to be desorbed. The desorption is to send a small amount of hot air into the adsorption wheel for heating and evaporation, so that the exhaust gas after catalytic combustion becomes a heat source for desorption. . The desorbed high-concentration exhaust gas is sent to the catalytic purification furnace 40 through the desorption circulating fan 30 for catalytic combustion (i.e., low-temperature oxidation), and the hot air discharged after the catalytic combustion is sent to the desorption zone 11B of the adsorption wheel 11 through the pipeline for desorption.
