Problems solved by technology

The disadvantage is that the solution to be concentrated flows directly in the heat collecting tube, which often leads to fouling of the coke tube.
Coke tubes and fouling will affect the transfer of heat energy. When the fouling is serious, there will be problems with blocked tubes, which leads to cleaning and maintenance problems
[0003] In addition, the solution often emits volatile gases during the evaporation process. If these gases are discharged directly, it will not only cause resource waste and environmental pollution, but also take away the heat in the solution evaporation system.

The apparatus has a reasonable structure design, and has a volatile gas recycling function; the tube is not easy to burn and scale.

Description

technical field [0001] The invention relates to the technical field of solution concentration, in particular to a solution evaporation separation concentration and crystallization device based on solar energy. Background technique [0002] Solution concentration devices are widely used in industrial production and daily life. Among them, solar solution concentration devices have unique advantages because they use clean and pollution-free solar energy. Most of the traditional solar solution concentration devices adopt the method of directly letting the solution flow in the solar collector tube to obtain heat energy. The disadvantage is that the coke tube fouling often occurs when the solution to be concentrated flows directly in the heat collecting tube. Coke tubes and fouling will affect the transfer of heat energy. When the fouling is serious, there will be problems of blocked tubes, which leads to cleaning and maintenance problems. [0003] In addition, the solution ofte...
