The invention provides a solvent recovery device and method. The solvent recovery device comprises a waste gas collection chamber, a cooling buffer tank, a multi-stage adsorption tank, circulating pumps, a concentration measuring device and a harmful gas detection device. Power supply is achieved through the circulating pumps of all parts. By means of the solvent recovery device and method, a resin solvent discharged in the running process of wet type gum dipping equipment can be recovered and reused, and recycling of the solvent is achieved; therefore, the consumption of a toxic solvent and the high cost of waste gas treatment are reduced, moreover, the low-content waste gas emission requirements can be met, and the win-win situation of the cost and the environmental friendliness is achieved; meanwhile, the gum dipping equipment does not need to consider the design of a safe protection device for the flammable, combustible and toxic gas, and a new approach is provided for the simplified design of the gum dip
