Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, in particular to an evaporator for waste heat power generation. Background Art

[0002] The evaporator is a crucial component among the four major components of a refrigeration system and is also a type of partition-type heat exchange device. The low-temperature condensed liquid passes through the evaporator, exchanging heat with the outside air, vaporizing and absorbing heat to achieve the cooling effect. Evaporators are categorized by operating pressure into three types: normal pressure, pressurized, and reduced pressure. Evaporators are divided into two main types: circulating and modular. They primarily consist of a heating chamber and an evaporation chamber. The heating chamber provides the heat required for evaporation, causing the liquid to boil and vaporize; the evaporation chamber completely separates the gas and liquid phases. The vapor generated in the heating chamber carries a large amount of liquid foam. Once in the larger evaporation chamber, this liquid is separated from the vapor by its own condensation or by the action of a demister.

[0003] The existing Chinese patent with publication number CN220524402U discloses an evaporator for ultra-low temperature waste heat power generation. The control motor drives the reciprocating threaded rod to rotate, and the rotation of the reciprocating threaded rod drives the threaded tube to move back and forth, so that the threaded tube drives the movable frame to move through the sliding rod, so that two cleaning brushes can reciprocate to clean the surface of the evaporator body to clean and drop the frost on the evaporator body. However, the evaporator in this device is a cylindrical tubular structure, and the cleaning brush is an elongated strip as a whole, so that it can only clean the maximum diameter surfaces on both sides of the evaporator, and thus the cleaning area is limited, resulting in poor cleaning effect and low practicality.
