Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
The small movable low-temperature evaporation device shown in fig. 1 comprises a distillation still 1, a condenser 2, a water tank 3, a water pump 4, a jet flow vacuum generator 5 and a heat exchange assembly 6. Are mounted in a movable housing (not shown) and wheels are provided on the bottom of the housing to allow the housing to be moved.
The distillation still 1 is connected with a stock solution inlet 11, a steam outlet 12 and a concentrated solution outlet 13. The liquid is introduced into the distillation still 1 from the stock solution inlet 11 and heated to evaporate. The top of the distillation still 1 is provided with a steam outlet 12. The steam outlet 12 is connected to the condenser 2. The steam is cooled in the condenser 2 to become condensed water. The liquid outlet of the condenser 2 is connected to a jet vacuum generator 5.
The water tank 3 is used for storing condensate. The water tank 3 is provided with a circulation pipe 7. Specifically, the liquid outlet end 71 and the liquid inlet end 72 of the circulating pipe 7 are respectively connected with the upper end and the lower end of the water tank 3. The water tank 3 is also provided with a distilled water outlet 73 for discharging condensed distilled water.
The main function of the circulation pipe 7 is to assist in the generation of vacuum. A water pump 4 and a jet vacuum generator 5 are arranged in the circulating pipe 7. The jet vacuum generator 5 is located on the pump-out side of the water pump 4. The water pump 4 passes the water flow through the jet flow vacuum generator 5 at a high speed, and the negative pressure is formed at the negative pressure interface 51 of the jet flow vacuum generator 5 under the high-speed water flow. A negative pressure is formed in the condenser 2 and the distillation still 1. The boiling point in the still 1 is lowered by the negative pressure. Such a low-temperature evaporation device realizes a small size.
The heat exchange assembly 6 is further arranged in the distillation kettle, so that heat exchange between the distillation kettle 1 and the condenser 2 is realized, a heating source and a cooling source do not need to be separately arranged, and the size of the device is further reduced.
The heat exchange assembly 6 comprises a compressor 61, a heating pipe 62, an expansion valve 63, a cooling pipe 64 and a medium cooling mechanism 65. The heat exchange assembly 6 forms a loop, which is composed of a compressor 61, a heating pipe 62 (located in the distillation still 1), a medium cooling mechanism 65, an expansion valve 63 and a cooling pipe 64 (located in the condenser 2) in sequence, the above components are connected by a pipeline, and a cooling medium, such as freon, is filled in the pipeline. The cooling medium is switched in the pipeline through states of gas, liquid, gas-liquid mixture and the like to realize heating in the distillation still 1 and cooling in the condenser 2. Due to the action of the compressor 61, the gaseous medium is compressed into a liquid state under high pressure, and in the process of converting the gaseous state into the liquid state, heat is released to the heating pipe 62 in the distillation still 1, so that the liquid in the distillation still 1 is heated. Due to the expansion valve 63, the liquid medium is vaporized from the liquid state to the gaseous state in the cooling pipe 64 due to the pressure reduction, and this vaporization process is a heat absorption process, thereby cooling the steam in the condenser 2 and condensing the steam. This is similar to the refrigeration principle of refrigerators and air conditioners. The heat exchange assembly 6 is used in the evaporation device of the embodiment, and compared with the conventional evaporation device, a separate heating source and a cooling source are not required, so that the volume of the device is favorably reduced.
In this embodiment, the medium cooling mechanism 65 is used to cool the medium in the pipeline, which is beneficial to the subsequent gasification of the medium to absorb heat.
In this embodiment, the heating pipe 62 and the cooling pipe 64 are both spiral structures, so that a larger contact area is provided with the surrounding stock solution or steam, and the heat exchange efficiency is improved.
The bottom of stills 1 is provided with concentrate export 13, and concentrate export 13 department is connected with fluid-discharge tube 8, is provided with positive displacement pump 9 in the fluid-discharge tube 8 to the realization is discharged the concentrate and is collected.
In summary, in this embodiment, the water pump 4 and the jet vacuum generator 5 are used to evacuate the distillation still 1, thereby achieving low-temperature evaporation and miniaturization of the apparatus. In addition, heat exchange is formed between the distillation still 1 and the condenser 2 through the heat exchange assembly 6, and a separate heating source and a separate cooling source are not required to be arranged, so that the miniaturization of the device is further realized. Wheels are arranged at the bottom of the box body to facilitate the movement of the device. Finally, a small and movable low-temperature evaporation device is realized.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
