AI Technical Summary
Technical Problem
Existing condensate recovery devices are prone to cavitation in low-pressure environments, which affects recovery efficiency and safety.
Method used
A closed-loop condensate recovery device was designed. By setting up a bypass pipe, adjusting the position of the inlet pipe, cavitation eliminator and steam-water separator, the inlet pressure of the water pump is increased, the generation of flash steam is reduced, and the flash steam and condensate are mixed by using an ejector device to improve the recovery rate.
Benefits of technology
It effectively reduces the risk of water pump cavitation, improves condensate recovery efficiency and system stability, ensures safety, and achieves efficient condensate recovery.
