They are generally composed of a first-effect heating chamber, a first-effect evaporation chamber, a second-effect heating chamber, a second-effect evaporation chamber, a steam-water separator, a water receiver, and a cooler.
[0003] Double-effect concentrators are devices that concentrate solutions by evaporation based on the principle of evaporation. They utilize two simultaneous evaporation processes, fully utilizing secondary steam and saving on boiler investment. Energy consumption is reduced by 50% compared to single-effect concentrators, thus broadening their application range. However, existing double-effect concentrators have the following problems: 1. The secondary processing requires a certain amount of time, preventing energy savings; 2. Existing double-effect concentrators are bulky, and once their position is fixed, their height cannot be adjusted or their location moved as required, thus necessitating improvement.

[0022] Example 1
[0023] Please see Figures 1-2This utility model provides an embodiment of a double-effect concentrator, comprising a first-effect evaporator 1, a first-effect heater 2, a second-effect evaporator 3, a second-effect heater 4, a condenser 5, and a receiving tank 6, all connected to each other. It also includes a fixed support plate 8. The first-effect evaporator 1 and the second-effect evaporator 3 are both fixed to the fixed support plate 8 via a support 7. Both ends of the fixed support plate 8 are respectively fixed to a lifting assembly. The two lifting assemblies are detachably mounted on a mounting base plate 9. The bottom of the mounting base plate 9 is provided with four universal casters 10. The lifting assembly includes a positioning support 11, a lifting screw 12, a threaded sleeve 13, and a drive motor 14. The positioning support 11 is detachably connected to the mounting base plate 9. For ease of disassembly, the positioning support 11 has an L-shaped structure. The horizontal plate of the positioning support 11 is fixed to the mounting base plate 9 by several locking screws 19. The lifting screw 12 is rotatably connected to the positioning support 11. Above, the output shaft of the drive motor 14 is connected to one end of the lifting screw 12 and drives the lifting screw 12 to rotate. The threaded sleeve 13 is threadedly connected to the lifting screw 12. The threaded sleeve 13 can move up and down along the lifting screw 12. The two ends of the fixed support plate 8 are respectively fixed on the corresponding threaded sleeve 13. In order to facilitate the fixing of the lifting screw 12, a positioning seat 16 is provided on the upper and lower sides of the outer side of the positioning support 11. The two ends of the lifting screw 12 are rotatably connected to the positioning seat 16.
