Sterilization equipment heat exchange system

Abstract

This case relates to a heat exchange system for sterilization equipment, comprising a plurality of modular heat exchangers, a gas flow path, a liquid flow path, and a liquid-to-gas flow path. Each modular heat exchanger includes a main body and a plurality of inner tubes. The gas flow path supplies gas via a main gas inlet pipe, through a secondary gas inlet pipe, a first connecting port of the main body, inner tubes, a second connecting port of the main body, and a secondary gas recovery pipe, and exits from the main gas recovery pipe. The liquid flow path supplies liquid via a main liquid inlet pipe, through a secondary liquid inlet pipe, a first orifice of the main body, and the interior of the main body. Inside the main body, the liquid exchanges heat with the inner tubes, at least partially vaporizing. The at least partially vaporized liquid exits from a second orifice of the main body and flows into a main pipe via a liquid-to-gas outlet pipe in the liquid-to-gas flow path. The vaporized liquid is then output to the sterilization equipment via the main gas outlet pipe through the main pipe.
