This multi-effect evaporator is easy to disassemble and repair, and can prevent the base from being corroded, but there are some defects and deficiencies that need to be improved: (1) Some existing multi-effect evaporators are relatively complex in design and manufacturing, requiring large-scale equipment and precise control systems, making it difficult to integrate and install various components together, which not only increases the initial investment cost of the equipment, but also increases the floor space, making it difficult to use in places with limited space; (2) Some existing multi-effect evaporators have certain heat losses during heat exchange and transfer, especially in multi-stage effects. The accumulated heat loss not only reduces the evaporation efficiency of the entire evaporator, but also increases energy consumption, which is not conducive to energy saving and environmental protection; (3) When evaporating and concentrating the solution, a large amount of condensed water is often generated, and some existing multi-effect evaporators lack corresponding condensed water recovery measures, making it difficult to centrally recover the generated condensed water, which is not convenient for subsequent reuse of the condensed water.

[0044] The working principle of the utility model is:

[0045] When the utility model is in use, firstly, the electrical components in the multiple-effect evaporator are connected to the external control switch and the power supply through the wires, and then after the solution to be concentrated is introduced into the preheating bin 10 through the liquid inlet 11, the sealing plug 12 is inserted into the liquid inlet 11, and then the first power supply seat 13 is used to supply power to each heating rod 24, and the heating rod 24 can generate heat after being energized. At this time, the heat generated by the heating rod 24 can be used to preheat the solution in the preheating bin 10, so as to reduce the energy consumption required for subsequent heating. After the preheating is completed, the preheated solution can be respectively introduced into each evaporation chamber 8 through each liquid guide tube 14, and then the second power supply seat 15 can be used to supply power to each heating wire 16, and the heating wire 16 can generate heat after being energized. At this time, the heat generated by the heating wire 16 can be transferred to each evaporation chamber 8 through the heat conduction plate 6 and the partition plate 7, so as to perform multiple-effect evaporation on the solution in each evaporation chamber 8, until the concentrated solution of the desired concentration is obtained, the valve on the liquid outlet pipe 9 can be opened to discharge the solution in each evaporation chamber 8, and then the solution is evaporated. When the evaporation is started, the solution in each evaporation chamber 8 will generate hot steam after being heated and evaporated. After the hot steam rises and contacts the bottom of the partition 7, it will gradually condense and form condensed water. The condensed water flows along the bottom surface of the partition 7 to both sides and then falls on the guide plate 21. The fallen condensed water can be introduced into the condensation bin 3 along the condensation port 5 through the guide plate 21 to realize the centralized recovery of the condensed water. After that, the valve on the drain port 4 can be opened to guide the condensed water in the condensation bin 3 for subsequent reuse. The waste heat generated in the multi-effect evaporation process can be centralized recovered through the heat collecting cover 17, and re-introduced into the shell 1 through each heat recovery pipe 19 to realize the reuse of the waste heat, thereby effectively reducing heat loss, not only improving the evaporation efficiency of the entire multi-effect evaporator, but also reducing energy consumption, which is beneficial to energy saving and environmental protection.
