摘要

采用Ansys Fluent软件研究高温熔盐混温罐混温过程的流动、传热及热力学特性

并分析不同结构对混温性能的影响。通过研究得到混温罐充盐过程罐内空气被熔盐加热造成一定的热量损失

使得实际的混温时间较理论计算时间长。在充盐过程

挡板结构层阻止一部分热流体与空气的换热

减少热量损失

挡板不开孔更有利于缩短混温时间。进口弯管结构中冷热流体接触充分

混温效果优于汇管结构。

Abstract

With the development of concentrated solar power generation technology and the need for heat recovery from industrial exhaust gases and high-temperature flue gases

high-temperature molten salt power generation technology plays an increasingly important role. In some cases

due to the process needs

it is necessary to mix the low-temperature molten salt with the high-temperature molten salt to reach the desired temperature. In this paper

Ansys Fluent software was used to study the flow

heat transfer and thermodynamic characteristics of the mixing process in the high temperature molten salt mixing tank

and the influence of different structures on the mixing performance was also analyzed. According to the results

it is obtained that the air inside the tank is heated by the molten salt during the salt charging process of the mixing tank

resulting in a certain amount of heat loss

which makes the actual mixing time longer than the theoretical calculation time. In the salt charging process

the baffle structure prevents part of the heat exchange between the molten salt and the air

which reduces the heat loss

and the baffle is more conducive to shorten the mixing time without opening holes. Besides

for elbow counter-current inlet type

the cold and hot molten salt fully contact when they were out from the inlet

which show better mixing result than the manifold inlet structure.
