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.

Abstract

The invention discloses a solution evaporation separation concentration and crystallization device based on solar energy, which includes a material tank, a solar heat collection tube, a solar heat collection plate, a first evaporator, a second evaporator and a steam recovery heat exchanger. The material tank is connected to the input end of the solar heat collecting pipe through the first liquid infusion pipe, and an infusion pump is arranged on the first liquid infusion pipe, and the output end of the solar heat collecting pipe is connected to the input end of the first evaporator. The upper end of an evaporator is provided with a first steam outlet, and the steam recovery heat exchanger is provided with a sealed heat exchange tank, and the heat exchange tank is provided with a first condensation pipe and a second condensation pipe in isolation. The output end of the second evaporator is externally connected to a storage tank, and the upper end of the storage tank is connected to the heat exchange tank body of the steam recovery heat exchanger for feeding. The invention has the advantages of reasonable structural design, recovery function of volatile gas, and less fouling of coke tubes.

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...
