The invention relates to the technical field of printing, in particular to an environment-friendly printing drying device. The environment-friendly printing drying device comprises a drying chamber, a hot air box, an air inlet pipe, a drying box, a condensation water collector, a circulating pipeline, a first pressure pump, a filter box, a heat exchanger, a second pressure pump, a first stop valve and a second stop valve. The drying force is gradually increased in the paper moving direction, so that wrinkles on the surface of the paper caused by shrinkage of the paper inside and outside the drying chamber due to the too large dry-wet difference are avoided, and then the surface quality of paper finished products is further improved.
