Low-temperature vacuum solvent recovery system for printing VOCs waste gas

The utility model discloses a low-temperature vacuum solvent recovery system for printing VOCs (Volatile Organic Compounds) waste gas. The low-temperature vacuum solvent recovery system comprises a filter, a cooler I, a molecular sieve rotating wheel, a fan, a cooler II, an activated carbon canister, a cooler III, a vacuum pump set, a condenser, a gas-liquid separator and a solvent storage tank which are sequentially communicated through a pipeline, the activated carbon canister comprises a canister body, an activated carbon layer is arranged in the canister body, a first box body and a second box body are correspondingly arranged at the two ends of the canister body, and a heat dissipation tube bundle penetrating through the canister body and the activated carbon layer is correspondingly communicated between the first box body and the second box body. The device saves energy and reduces consumption, achieves standard emission of VOCs waste gas and solvent recovery through molecular sieve rotating wheel conce
