[0002] In the chemical production process, many places need to concentrate and evaporate the solution to increase the concentration, making other processes more economical and reasonable. Normal pressure evaporation or reduced pressure evaporation is usually used. The entire concentration process requires the solution to be heated to boil, and the water or other volatile solution parts are vaporized and continuously removed to achieve the concentration of solid matter or solutes in the solution.

[0003] However, in the prior art, the installation time of the barrel cover is too long, which may cause unnecessary evaporation or chemical changes in the liquid in the barrel during the installation process, affecting product quality. The long installation time will delay the commissioning of the equipment, affecting the overall production efficiency and progress. At the same time, due to uneven heating, the evaporation rate of the concentrated liquid is different at different stages, which may lead to inconsistent concentration of the final product or precipitation. Uneven heating will cause local overheating, increase equipment wear and failure rate, and shorten the service life of the equipment. In response to this technical problem, the present application proposes a multi-stage evaporation and concentration equipment. Utility Model Content
