Device for recovering hydrogen fluoride from pentafluoroethane crude product

The utility model relates to a device for recovering hydrogen fluoride from a pentafluoroethane crude product. The sealing heads comprise a first sealing head and a second sealing head, and the first sealing head and the second sealing head are symmetrically arranged at the two ends of the cylinder body and detachably connected with the cylinder body; the feeding pipeline is fixedly connected with the first sealing head, and the feeding end of the feeding pipeline is communicated with an outlet pipeline of a feeding cooler of the water scrubber; the coalescers are respectively arranged at the two ends in the barrel body and are used for separating hydrogen fluoride from pentafluoroethane, so that cyclic utilization of hydrogen fluoride is realized, the economic value of hydrogen fluoride is improved, the loss of hydrogen fluoride in the preparation process of pentafluoroethane is further reduced, and the production cost is further reduced; and meanwhile, the sealing head is arranged on the cylinder body by ad
