Objective To reduce the temperature of waste water and gas through a heat exchanger so it can bedischarged in a polyvinyl chloride (PVC) pipe, and so the heat energy can be controlled by arranging the temperaturesensor at the critical control node. Methods High temperature gas and liquids were exchanged efficiently using a heatexchanger 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°C and the water temperatureafter heat transfer was reduced. In the heat recovery process, the heat recovery efficiency reached 72%. Conclusions Theproblem of air pollution caused by high temperature and high pressure gas discharge is reduced allowing energy saving and emission reduction.
