A heat exchanger is increased in the entire circulatory system, the low temperature weak solution for high-temperature gas and the absorber outflow for allowing generator to flow out
Heat exchange is carried out, the temperature that weak solution enters generator is improved.
Currently, the heat exchanger that production caustic soda uses includes the chamber for being connected to lithium-bromide solution import and lithium-bromide solution outlet
Body is provided with the heat exchanger tube of multiple connection steam condensation water imports and steam condensation water outlet in the cavity.Due to being needed in heat exchanger
Pass through two media simultaneously, and the larger service life for allowing for heat exchanger tube of the temperature difference of heat exchanger tube inside and outside wall reduces, and portion
Divide heat exchanger tube to scrap, to scrap on entire heat exchanger, considerably increase equipment cost；Meanwhile traditional heat exchanger tube is in unit
Circulation on section is smaller, and heat-exchange time extends, it is easy to which the temperature for gas temperature and lithium-bromide solution occur neutralizes, heat exchange
Effect is not added.
Utility model content
