[0023] The following further describes the present utility model in conjunction with the accompanying drawings and specific implementation schemes:
[0024] As Figure 1 - Figure 2As shown in the figure, a multi-effect energy-saving rotary dehumidification system includes a proportional-integral three-way water valve 9, a water-cooled condenser 26, a precooling finned-tube cooler 19, a first finned-tube evaporator 17, a second finned-tube evaporator 18, a first finned-tube condenser 15, a second finned-tube condenser 16, a rotary dehumidifier 22, a regeneration heat recovery machine 25, a refrigeration compressor 24, a regeneration finned-tube cooler 20, and an electric heater 23. The first end of the proportional-integral three-way water valve 9 and the refrigerant inlet of the water-cooled condenser 26 are both connected to a water inlet pipe (not shown in the figure) to introduce an external water source through the water inlet pipe. The introduced external water source can be low-temperature groundwater or other water sources. For example, when applied in the underground powerhouse of a hydropower plant, the water source of a reservoir can be introduced. The second end of the proportional-integral three-way water valve 9 is connected to an outlet pipe, and the outlet pipe is used to discharge the water flow inside the rotary dehumidification system to the outside. The third end of the proportional-integral three-way water valve 9 is connected to the refrigerant outlet of the water-cooled condenser 26.
[0025] In an optional embodiment, a temperature sensor 7 and a third pressure sensor 8 are further installed on the outlet pipe. The temperature sensor 7 and the third pressure sensor 8 are electrically connected to the proportional-integral three-way water valve 9 so as to be able to adjust the opening degree of the proportional-integral three-way water valve 9 according to the temperature and pressure parameters measured by the temperature sensor 7 and the third pressure sensor 8.
[0026] The outlet pipe is also respectively connected to the first input end of the regeneration finned-tube cooler 20 and the first input end of the precooling finned-tube cooler 19 through an outlet pipeline 4, and the water inlet pipe is also respectively connected to the second input end of the regeneration finned-tube cooler 20 and the second input end of the precooling finned-tube cooler 19 through a water inlet pipeline 3.
[0027] The output end of the water-cooled condenser 26 is respectively connected to the input end of the first finned-tube evaporator 17 and the input end of the second finned-tube evaporator 18. The water-cooled condenser 26 can be connected to the first finned-tube evaporator 17 and the second finned-tube evaporator 18 through pipelines. A check valve 11, a dryer filter 12, and a throttling expansion valve 13 are also installed on the connection path between the water-cooled condenser 26 and the first finned-tube evaporator 17 and the second finned-tube evaporator 18.
[0028] The dryer filter 12 is used to filter impurities and absorb moisture, and the throttling expansion valve 13 is used for throttling. A check valve 11 is also installed on the connection path, and the check valve 11 is located on the side of the connection path close to the output end of the water-cooled condenser 26.
[0029] The input end of the drying filter 12 is provided with a coarse metal mesh, and the output end is a fine metal mesh, so that larger particulate impurities can be effectively filtered out. Moreover, a desiccant with excellent moisture absorption characteristics is placed between the two metal meshes to absorb the moisture in the refrigerant output from the output end of the water-cooled condenser 26, ensuring the smoothness of the communication path and the normal use of the refrigerant in the subsequent finned evaporator. The communication path can be a capillary tube or other types of pipes.
[0030] The throttling expansion valve 13 plays a throttling role by adjusting the flow rate, which can convert the high-temperature and high-pressure liquid refrigerant into a low-temperature and low-pressure mist-like refrigerant, creating conditions for the evaporation of the refrigerant. It can also automatically adjust the flow rate of the refrigerant entering the evaporator according to the heat signal obtained by the temperature sensor 7 to adapt to the change of the refrigeration load. At the same time, it can also maintain the superheat degree. By adjusting the flow rate, it can keep the evaporator within a certain superheat degree range to prevent abnormal overheating.
[0031] The output end of the second finned evaporator 18 is respectively connected in communication with the input end of the first finned evaporator 17 and the input end of the refrigeration compressor 24. A first pressure sensor 5 is also installed on the communication path between the second finned evaporator 18 and the refrigeration compressor 24. The second finned evaporator 18 can be respectively connected in communication with the input end of the first finned evaporator 17 and the input end of the refrigeration compressor 24 through the first pipeline 1.
[0032] The output end of the refrigeration compressor 24 is connected in communication with the input end of the first finned condenser 15 and the input end of the second finned condenser 16. The refrigeration compressor 24 can be connected in communication with the first finned condenser 15 and the second finned condenser 16 through pipelines.
[0033] In an alternative embodiment, a second pressure sensor 6 is also installed on the communication pipeline between the refrigeration compressor 24 and the first finned condenser 15 and the second finned condenser 16.
[0034] The output ends of the first finned condenser 15 and the second finned condenser 16 are respectively connected in communication with the input end of the water-cooled condenser 26 and the pipeline where the drying filter 12 is located through the second pipeline 2. A solenoid valve 10 is also installed on the second pipeline 2. The first finned condenser 15 and the second finned condenser 16 are connected in communication with the first finned evaporator 17 and the second finned evaporator 18 through the pipeline where the drying filter 12 is located.
[0035] In an alternative embodiment, a filter 21 is also installed in front of the precooling surface cooler 19. The filter 21 is used to filter out impurities such as dust. The filter 21 is located at the upper air inlet ( Figure 1 the A position at the place is within the range of the upper air inlet).
[0036] Along the wind direction, the precooling finned-tube cooler 19, the first finned evaporator 17, the second finned evaporator 18, and the first finned condenser 15 are sequentially arranged on the air inlet path.
[0037] The second finned condenser 16, the electric heater 23, and the regeneration finned-tube cooler 20 are all located on the regeneration air path and are sequentially arranged along the wind direction. The regeneration air path includes a first path and a second path, and the wind directions of the first path and the second path are exactly opposite. The second finned condenser 16 and the electric heater 23 are located on the first path, and the regeneration finned-tube cooler 20 is located on the second path.
[0038] The rotary dehumidifier 22 straddles the air inlet path and the first path of the regeneration air path, and the regenerative heat recovery machine 25 straddles the first path and the second path of the regeneration air path. The regenerative heat recovery machine 25 includes a first channel and a second channel, and the inner cavities of the first channel and the second channel are interconnected. The first channel is located on the first path, and the second channel is located on the second path.
[0039] The end of the air inlet path (i.e., the final air outlet) is connected to the front end of the regeneration air path (i.e., the initial air inlet), and the air flowing out of the end of the air inlet path can be redirected to flow into the regeneration air path. Among them, the end of the air inlet path and the front end of the regeneration air path are in the same air-circulating space area.
[0040] Figure 1 Among them, A→B→C→E→F→G is the air inlet path along the wind direction. O→P→Q→R→S is the regeneration air path along the wind direction, O→P is the first path, and Q→R→S is the second path.
[0041] In an alternative embodiment, a first air blower 14 is further arranged behind the first finned condenser 15 on the air inlet path along the wind direction.
[0042] In an alternative embodiment, a second air blower 27 is further arranged behind the regeneration finned-tube cooler 20 on the regeneration air path along the wind direction.
[0043] Among them, the air inlet path and the regeneration air path can be pipelines or space channels (such as rooms) within a building that allow air to flow.
[0044] The rotary dehumidifier 22 is located at the end of the first path, and the regenerative heat recovery machine 25 straddles the front end of the first path and the end of the second path.
[0045] In actual use, the wet air flowing in from the upper air outlet A first passes through the pre-cooling surface cooler 19 for primary dehumidification, then flows into the second finned evaporator 18 for dehumidification, and then flows into the rotary dehumidifier 22 for treatment. The treated air becomes a high-temperature and low-humidity state. The high-temperature and low-humidity air then flows into the first finned evaporator 17 and is cooled to obtain low-humidity air with a suitable temperature. Among them, if the temperature of the air output after treatment by the rotary dehumidifier 22 is low, it can be heated by the first finned condenser 15. Thus, three dehumidification modes can be provided according to different scenarios.
[0046] Dehumidification mode 1: using the pre-cooling surface cooler 19 for pre-dehumidification.
[0047] Dehumidification mode 2: After pre-dehumidification using the pre-cooling surface cooler 19, two finned evaporators are continued to be used for deep dehumidification.
[0048] Dehumidification mode three: On the basis of dehumidification mode two, that is, after pre-dehumidification using the pre-cooling surface cooler 19, two finned evaporators and a rotary dehumidifier 22 are continued to be used for maximum depth dehumidification to achieve the highest dehumidification capacity, which can meet the application scenarios of large factories and workshops with groundwater and other spaces requiring a large dehumidification capacity.
[0049] The above three dehumidification modes can be manually or automatically selected according to the air humidity content at the upwind outlet, and on the premise of meeting the dehumidification requirements, energy saving can be achieved by shutting down corresponding equipment components.
[0050] The dry air output from the air inlet path becomes regeneration air, and the regeneration air passes through the regeneration heat recovery machine 25 twice on the first path and the second path, which can preheat the regeneration air and achieve energy saving effect. The air output by the regeneration heat recovery machine 25 is first heated once by the second finned condenser 16 (can be heated to about 70°C), and then heated before entering the electric heater 23, which can effectively save the electric power of the electric heater 23 and achieve energy saving effect.
[0051] The unused condensation heat of the first finned condenser 15 and the second finned condenser 16 can be dissipated through the water-cooled condenser 26, and the water-cooled condenser 26 does not need a cooling water tower and can directly use groundwater for heat dissipation, thereby achieving energy-saving effects.
[0052] For the wet air (i.e., regeneration air) of the regeneration exhaust, in order to reduce the connection and the power distribution of the blower, although it can be discharged near the unit, the wet air can easily be directly sucked into the unit together with the treated air, which may cause the machine room environment to be too humid. In order to avoid this situation, a surface cooler is configured at the same time. The surface cooler is connected to low-temperature groundwater inside, so that the moisture on the air side can be directly condensed into condensed water and then directly discharged into the ditch.
[0053] The utility model can provide three dehumidification modes according to different scenario requirements, with better energy-saving effect, better meeting customer needs and improving user experience.
[0054] The embodiments disclosed in this specification are only an illustration of the unilateral features of the utility model. The protection scope of the utility model is not limited to this embodiment, and any other functionally equivalent embodiments fall within the protection scope of the utility model. For those skilled in the art, various corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all these changes and deformations should fall within the protection scope of the claims of the utility model.
