Gas purification (such as polysilicon hydrogen purification, chemical tail gas purification and the like), VOC waste gas treatment and the like all need to use an adsorption system or related processes. It is well known that the adsorption process is a strongly exothermic process, while the desorption process is a strongly endothermic process, and thus it is necessary to cool it while adsorbing, and to heat it while desorbing. At present, a heat exchange tube is added in an adsorption column, then cooling water or other materials with lower temperature are introduced to cool the adsorption column during adsorption, and high-temperature water or other materials with higher temperature are introduced to heat the adsorption column during desorption. When the adsorption is changed to desorption or the desorption is changed to adsorption, the material in the heat exchange tube can be suddenly heated or quenched, and the stress caused by the temperature difference easily cracks the joint of the heat exchange tube and the tube frame, so that equipment is damaged, and particularly when an adsorption system is used as an important or key device, the risk of sudden heating or quenching is very high. In order to solve the problems, part of manufacturers adopt a method of slowly feeding cooling or heating media into the adsorption column heat exchange tube, and the method can delay the service life of an adsorption system to a certain extent, but the treatment is not the primary and secondary treatment.
