System and method for simultaneous adsorption concentration and condensation recovery

The invention provides an adsorption concentration and condensation recovery system and method, and belongs to the technical field of waste gas treatment. The system comprises a waste gas inlet, an adsorption device, a circulating desorption loop, a circulating cooling and desorption loop and a nitrogen supply unit. An inlet of the circulating desorption loop is connected with a desorbed gas outlet of the adsorption device, and an outlet of the circulating desorption loop is connected with a desorbed gas inlet of the adsorption device; the circulating cooling and desorption loop and the circulating desorption loop are arranged in parallel; and the nitrogen supply unit is connected to the circulating desorption loop and is used for nitrogen replacement and nitrogen desorption of the system. According to the system and the method, a mode of coupling internal circulation desorption, external circulation desorption and circulation condensation is adopted, so that the circulation air quantity of condensation exter
