Abstract
A solvent recovery device for a polyimide fiber spinning and curing area comprises a channel body, wherein spun fibers pass through the channel body; a spun fiber curing area is arranged at the lower part of the channel body; linked opening/closing doors are arranged at the bottom end of the channel body; a dual-rectangular-shaped box body is arranged outside the spun fiber curing area; air holes are formed in outer walls on two sides of the spun fiber curing area; a hot air outlet is arranged on the outer wall of the dual-rectangular-shaped box body; a water tower is arranged outside the channel body; and a hot air inlet pipe is arranged at the upper part of the water tower and connected with the hot air outlet through a connecting pipeline. According to the solvent recovery device, by the aid of a condenser and a fan which are arranged on the connecting pipeline, hot air is in a balanced state during spinning of polyimide fibers, and the operating performance of the fiber spinning is improved; and by the aid of the water tower absorbing a DMAC (dimethylacetamide) solvent, the amount of the DMAC solvent discharged into the atmosphere is reduced, the atmospheric pollution is avoided, and meanwhile, the DMAC solvent can be recycled, so that waste of resources is avoided, and the utilization rate of the DMAC solvent is increased.
