Abstract
This utility model discloses a phosphorus oxychloride condensation and recovery device, belonging to the field of phosphorus oxychloride condensation and recovery technology. The key technical features include a condensation tank, with a condensation mechanism fixedly connected to the inner wall of the condensation tank and an auxiliary mechanism fixedly connected to the surface of the condensation tank. The condensation mechanism includes a low-temperature inlet pipe, a storage tank, a water bucket, a condenser pipe, a conveying frame, an air inlet pipe, a water tank, a water pump, and a circulating water pipe. The low-temperature inlet pipe is fixedly connected to the inner wall of the condensation tank, and the storage tank is fixedly connected to the bottom of the low-temperature inlet pipe. By setting up the condensation mechanism, circulating water can pre-condense most of the phosphorus oxychloride vapor, reducing subsequent load. After pre-condensation, the vapor enters the inner wall of the storage tank and undergoes secondary condensation through a low-temperature cooling medium, achieving multi-stage condensation. Combined with the design of the condenser pipe and spiral channel, the condensation path of the vapor is extended, enhancing the heat transfer effect and improving the condensation efficiency.
