Abstract

The invention provides an efficient and rapid film evaporator which comprises a shell, an evaporation pipe set, an exhauster and a flow divider, the evaporation pipe set is arranged in the shell, the exhauster is rotationally arranged on evaporation pipes of the evaporation pipe set, and the flow divider divides liquid ammonia entering an evaporation chamber. The exhauster mounted on the evaporation pipes is driven to rotate by force generated by flowing of liquid ammonia from bottom to top, so that gas formed by evaporation of a liquid ammonia film on the evaporation pipes can be quickly dissipated, gas blocking is avoided, subsequent liquid ammonia quickly forms a new liquid ammonia film on the evaporation pipes, the heat exchange efficiency of the evaporation pipes is improved, and the energy consumption of the evaporation pipes is reduced. In cooperation with the flow dividing effect of the flow divider on the liquid ammonia, the liquid ammonia is distributed more uniformly, and the technical problem that gas hinders the liquid in the gas-liquid transferring process is solved.

Description

technical field [0001] The invention relates to the technical field of the mechanical structure of a thin film evaporator, in particular to an efficient and fast thin film evaporator. Background technique [0002] The thin-film evaporator adopts the principle of rising film evaporation. The refrigerant is sprayed into and evaporated through the liquid supply distribution system at the bottom of the evaporator. The evaporated gas moves upward with tiny refrigerant droplets during the rising process, and the droplets touch the wall of the heat exchange tube. Finally, high-efficiency evaporation is formed, which can achieve a large heat transfer coefficient and high-efficiency heat transfer. Under the same heat transfer conditions, the use of thin-film evaporators can save a large amount of heat transfer area compared with traditional shell-and-tube evaporators. [0003] In the Chinese patent with the patent number CN101785930B, a tubular thin film evaporator is disclosed, whic...
