Abstract
The invention discloses an organic exhaust gas concentration adjusting system, which relates to the technical field of waste gas treatment equipment. The organic exhaust gas concentration adjusting system comprises an air feeding unit, an exhaust gas treatment unit, a detection unit, and a control unit. The organic exhaust gas concentration adjusting system related in the invention is provided with an absorption/desorption box internally consisting of a plurality of groups of fan wheels and modified silica-based molecular sieves. Since the air volume in the system is large enough to drive the fan wheels to rotate, the air absorption amount is increased; and matters subjected to cooling absorption fall on the inner walls of the absorption/desorption box via centrifugal force generated through rotation of fan wheels. Therefore, the matters subjected to cooling absorption are convenient for centralized collection and exportation, and the energy consumption is reduced. Furthermore, the modified silica-based molecular sieves has an absorption capability better than that of active carbon, so that the problem of acid corrosion due to vapor desorption is solved, and the service life of the equipment is greatly improved. The organic exhaust gas concentration adjusting system is high in absorption/desorption efficiency, good in quality, simple in structure, and low in cost.
