摘　　要：目的通过换热器降低高压蒸汽灭菌器排放废汽废水的温度,使之能在PVC管道中排放,回收排放的废汽废水中的热能加以利用,降低排放废汽造成的环境污染。方法通过采用热交换器元件,对排放的高温气体和液体进行高效热交换。并通过在关键控制节点布置温度传感器的方法,对交换过程中的温度进行精密控制。结果灭菌器停止工作后,蒸汽排出温度降低到15℃,换热后水温也随之降低。在有效热回收过程中,热回收效率达到72%。结论解决高温高压灭菌器高温气体排放及所造成的空气污染问题,实现节能减排。Objective To reduce the temperature of waste water and gas through a heat exchanger so it can be discharged in a polyvinyl chloride (PVC) pipe, and so the heat energy can be controlled by arranging the temperature sensor at the critical control node. Methods High temperature gas and liquids were exchanged efficiently using a heat exchanger element. The temperature sensor was arranged at the key control node to control the temperature precisely. Results After the sterilizer was stopped, the steam discharge temperature was reduced to 15℃ and the water temperature after heat transfer was reduced. In the heat recovery process, the heat recovery efficiency reached 72%. Conclusions The problem of air pollution caused by high temperature and high pressure gas discharge is reduced allowing energy saving and emission reduction.
