[0014] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0015] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Example 1:

[0016] like Figure 1 and Figure 2 As shown, an MVR distillation system with a microwave distillation device includes an MVR distillation device 2, a microwave distillation device 1 at the front end of the MVR distillation device 2, and a microwave generator 3 connected to the microwave distillation device 1 via a waveguide 11. The microwave distillation device 1 includes a liquid storage cylinder 12 mounted on the waveguide 11 and a vapor exhaust pipe 13 mounted on the top of the liquid storage cylinder 12. The upper part of the outer wall of the liquid storage cylinder 12 is provided with a liquid inlet 15, and the lower part of the outer wall of the liquid storage cylinder 12 is provided with a liquid outlet 16. The microwave generator 3 heats and distills the liquid in the liquid storage cylinder 12 via the waveguide 11.

[0017] In actual operation, the raw liquid enters the storage tank 12 through the inlet 15 of the microwave distillation device 1. The microwave generator 3 heats and distills the liquid in the storage tank 12 through the waveguide 11. After heating, the water in the raw liquid turns into steam and is discharged from the steam outlet 13, thus concentrating the raw liquid. The concentrated liquid is discharged from the outlet 16 and enters the MVR distillation device 2 for distillation, thus changing the concentration of the liquid or separating different liquids. The microwave distillation device 1 is used to preheat the liquid, which has high efficiency of penetrating heating and low energy loss. It also occupies a small area, has wide applicability, and low operating cost.

[0018] MVR is the abbreviation for mechanical vapor recompression. An MVR distillation unit is also called an MVR evaporator. MVR is an energy-saving technology that reuses the energy of the secondary steam it generates, thereby reducing the demand for external energy.

[0019] A condenser pipe 14 is provided at the top of the steam discharge pipe 13. This is used to cool the steam discharged from the steam discharge pipe 13, preventing the steam from directly escaping and scalding workers, thus improving safety.

[0020] The upper end of the condenser tube 14 is provided with a water inlet pipe 141, and the lower end of the condenser tube 14 is provided with a water outlet pipe 142. Water enters through the water inlet pipe 141 to cool the steam in the condenser tube 14, and after removing the heat from the steam, it is discharged from the water outlet pipe 142. The discharged hot water can be used for heat recovery and utilization, reducing energy consumption.

[0021] The top of the steam exhaust pipe 13 is provided with an adjustable adapter pipe 131, and the condenser pipe 14 is connected to the adjustable adapter pipe 131. This facilitates the adjustment of the position of the steam exhaust pipe 13, making it suitable for installation requirements in different locations and offering wide applicability.

[0022] A pressure gauge 17 is installed on the top of the liquid storage cylinder 12. It is used to measure the pressure inside the liquid storage cylinder 12, so as to adjust the flow rate of the raw liquid through the liquid storage cylinder 12 in a timely manner and thereby adjust the pressure and eliminate safety hazards.

[0023] The steam discharge pipe 13 is equipped with a retaining ring 19 that is connected to the pressure gauge 17. The retaining ring 19 secures the pressure gauge 17, preventing it from shaking and being damaged, and extending its service life.

[0024] The bottom of the waveguide 11 is provided with a support frame 18. This supports the entire microwave distillation device 1 and increases its stability. The support frame 18 can also be configured with an adjustable height to suit the installation requirements of different locations. Example 2:

[0025] like Figure 3 As shown, for reference Figure 1 Based on Embodiment 1, the MVR distillation apparatus 2 is equipped with a solid-liquid separator 4 at its rear end. During the distillation of the concentrate by the MVR distillation apparatus 2, crystals will be generated. The solid-liquid separator 4 is used to separate the crystals and recycle them, which can avoid resource waste.

[0026] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
