A condensation recovery system is a device commonly used in the chemical and pharmaceutical industries to recover and separate gases by condensing gases, such as steam, into liquids in a device through cooling and condensation methods. Its main function is to manage gases containing harmful gases or pollutants, and it is widely used in industrial environments such as chemical and pharmaceutical industries. In certain production processes, chemical, pharmaceutical and other industries need to use a large number of substances in the gaseous state, these gaseous substances will be brought out at the same time like pollutants in the production process, if there is no recovery and treatment of these gases, it will cause great harm to the environment and human health. Therefore, the use of condensation recovery system can achieve the purpose of energy saving and environmental protection and reduce the pressure of environmental protection. The principle of the condensation recovery system is based on the heat transfer and phase change of the gas as it flows through the condensing pipes. When the gas flows in the pipeline, it will take away a lot of heat. When the temperature of the pipeline drops below its dew point, the water vapor in the gas will condense into liquid, thus realizing the recovery of the gas. For harmful pollutants such as chemicals, specific solutions are added to the condensation recovery system to eliminate their toxicity through chemical reactions.
