Problems solved by technology
[0002] As we all know, mechanical compression heat pump (MVR for short) technology and multi-effect vacuum evaporation (ME for short) technology in evaporative salt production technology both have the disadvantage of high energy consumption. Since the salt production industry is a high energy-consuming industry, its development is subject to national industry Policy constraints, and for enterprises, the above-mentioned evaporative salt production technology has disadvantages such as complete machine shutdown for maintenance, complicated installation and commissioning, and inability to freely adjust and reduce production line production capacity. How to change this pattern and provide a relatively low energy consumption , easy maintenance, simple installation and debugging, and a salt making device that can freely adjust the production line capacity are the main technical problems to be solved by the present invention

Embodiment Construction
[0027] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.
[0028] Such as figure 1 As shown, a low-temperature heatless vacuum salt-making device includes: an evaporation system consisting of an evaporation tank 1, a heat exchanger 2, and a forced evaporation circulation pump 3 arranged between the evaporation tank and the heat exchanger, brine Preheater 4 is formed, because this device adopts single-effect evaporation, so the diameter of evaporating pot is selected larger, and the diameter selected in the present embodiment is controlled at about 2m, and described brine preheater 4 is also provided with a condensed water outlet, and described A brine pump 5 is provided at the inlet end of the brine preheater, and a first electric regulating valve 6 is provided on the pipeline between the outlet of the forced evaporation circulation pump and the inlet of the heat exchanger, and the pipe between the ou...
