Abstract

The invention provides an adsorption recovery system for nitrogen regeneration and an adsorption recovery method thereof, which belong to the field of adsorption recovery. The system comprises waste gas input equipment, primary adsorption equipment and secondary adsorption equipment which are connected in sequence, and further comprises a nitrogen replacement pipeline, and a primary circulating nitrogen desorption pipeline and a secondary circulating nitrogen desorption pipeline which are connected with the primary adsorption equipment and the secondary adsorption equipment respectively, the primary circulating nitrogen desorption pipeline and the secondary circulating nitrogen desorption pipeline are respectively communicated with the nitrogen replacement pipeline; desorption gas condensation recovery equipment is arranged on each of the primary circulating nitrogen desorption pipeline and the secondary circulating nitrogen desorption pipeline; wherein the primary adsorption equipmentcomprises at least two adsorption tanks which are connected in parallel, and the secondary adsorption equipment is an adsorption rotating wheel. By adopting the system and the method provided by theinvention, the specification of the adsorption device can be obviously reduced, the filling amount of the adsorption material is greatly reduced, the switching period is greatly shortened, the safetyis high, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of adsorption recovery, in particular to an adsorption recovery system for nitrogen regeneration and an adsorption recovery method thereof. Background technique [0002] The high-concentration organic waste gas discharged in the coating, evaporation and drying processes of the printing industry, fiber industry, resin industry and other fields has a high recovery value. In the industry, activated carbon can be used for adsorption and recovery. For water-soluble solvents, hot nitrogen gas is mostly used to Activated carbon is desorbed, and the desorbed hot nitrogen containing solvent is condensed and recovered by the condenser. However, the saturation concentration of the waste gas is generally large after condensation. Relying on condensation alone will cause a large amount of high-concentration solvent to remain in the activated carbon tank. If the activated carbon tank is adsorbed again, it will The residual solvent ...
