With the rapid development of China’s evaporative crystallization equipment market and the continuous expansion of product output, the national industrial policy encourages the evaporative crystallization equipment industry to develop towards high-tech products, and the investment of new investment projects of domestic enterprises gradually increases. Investors pay more and more attention to the evaporation crystallization equipment market, and the high salt wastewater treatment technology is widely used. In the process of wastewater treatment, evaporation and crystallization are important operation units, which are the key technologies for waste recycling and reduction. Experts pointed out that the evaporator will have great changes in the next five years. The main change is not in technology, but in the integration of market scale, marketing system, management system and other aspects. The whole industry of evaporator will usher in a new round of golden period of development. High efficiency, energy saving and environmental protection have become the mainstream trend of the whole machine market. On the basis of the existing evaporator products, the future development of the evaporator will comply with the development trend of the whole machine, ushering in new technological breakthroughs and market breakthroughs.
