Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of rotary dehumidifiers, and more specifically, to a rotary dehumidifier and regeneration device and system thereof. Background Technology
[0002] A rotary dehumidifier is a dehumidification device. When humid air needs dehumidification, it passes through the processing area of the rotary wheel. The water vapor in the humid air is adsorbed by the solid desiccant in the wheel, and the dry air is sent to the space requiring treatment by the processing fan. Meanwhile, the slowly rotating wheel carries the nearly saturated water vapor into the regeneration zone. In the regeneration zone, high-temperature air blown in the opposite direction desorbs the adsorbed moisture in the wheel and is discharged outdoors by the fan, thus restoring the wheel's moisture absorption function and completing the regeneration process. The wheel rotates continuously, and the above dehumidification and regeneration are repeated cyclically, ensuring a continuous and stable dehumidification state for the dehumidifier. The energy consumption for dehydration in the regeneration zone is the highest in the entire process. Currently, the most common dehydration methods for rotary dehumidifiers are electric heating, steam heating, and natural gas heating. However, these methods of directly heating to generate high-temperature air are relatively inefficient and energy-intensive. How to reduce the energy consumption of dehydration in the regeneration zone is a major concern in the industry.
[0003] In recent years, some researchers have proposed systems that utilize heat pumps to heat and generate high-temperature air. A heat pump is a device that extracts low-grade heat energy from the air, water, or soil in nature, and then uses electrical energy to provide usable high-grade heat energy. A heat pump system generally consists of four parts: a compressor, a condenser, a throttling element, and an evaporator. Its working process is as follows: a low-temperature, low-pressure liquid refrigerant (such as Freon) first absorbs heat from a high-temperature heat source (such as room-temperature air) and vaporizes into low-pressure vapor in the evaporator (such as an indoor air conditioner unit). Then, the low-pressure vapor is compressed into high-temperature, high-pressure vapor in the compressor. This high-temperature, high-pressure vapor is cooled and condensed into a high-pressure liquid in the condenser by a low-temperature heat source (such as cooling water), and then throttled into a low-temperature, low-pressure liquid refrigerant by a throttling element (such as a capillary tube, thermostatic expansion valve, or electronic expansion valve). This completes one refrigeration cycle.
[0004] However, existing systems that use heat pumps to heat and generate high-temperature air consume a lot of electricity because the entire system requires the compressor to do work. Utility Model Content

Figure 3 The solid line shown illustrates the flow of the fourth medium. Figure 4The solid line shown illustrates the flow of the second medium solution. Figure 4 The dashed lines shown illustrate the flow of the third medium; Figure 5 The solid line shown illustrates the flow of the first medium. Figure 5 The dashed lines shown illustrate the flow of humid air through the processing area of the rotor to form dry air. Figure 6 A schematic diagram of the evaporator structure is shown. Figures 1-6 The arrows in the diagram indicate the direction of flow for each medium.
[0052] The rotor includes a processing area and a regeneration area. The processing area is used to dehumidify humid air, and the regeneration area is used to restore the rotor's moisture absorption function to complete the regeneration process.
[0053] The rotary dehumidifier and regeneration device provided in this embodiment can be used for dehydration in the regeneration zone of the rotary wheel 700, so that the rotary wheel 700 can restore its moisture absorption function. See also Figures 1-6 As shown, the rotary dehumidification and regeneration device includes a generator 100, a condenser 200, an evaporator 300, and an absorber 400.
[0054] The generator 100 includes two independently configured first flow channel 110 and second flow channel 120, which are not interconnected within the generator 100. The condenser 200 includes two independently configured first flow channel 210 and second flow channel 220, which are not interconnected within the condenser 200. The evaporator 300 includes two independently configured first flow channel 310 and second flow channel 320, which are not interconnected within the evaporator 300. The absorber 400 includes two independently configured first flow channel 410 and second flow channel 420, which are not interconnected within the absorber 400.
[0055] The second flow channel 120 of the generator is connected end to end with the second flow channel 420 of the absorber so that the second medium solution circulates within the second flow channel 120 of the generator and the second flow channel 420 of the absorber. The second medium solution in the second flow channel 120 of the generator is configured to be heated by the first medium in the first flow channel 110 of the generator so that at least part of the solvent in the second medium solution evaporates to form a third medium, which is then transported to the second flow channel 220 of the condenser. The second flow channel 120 of the generator, the second flow channel 220 of the condenser, the second flow channel 320 of the evaporator and the second flow channel 420 of the absorber are connected in sequence and used for the flow of the third medium.
[0056] like Figure 3As shown, the outlet of the first flow channel 410 of the absorber is connected to the inlet of the first flow channel 210 of the condenser. The first flow channel 410 of the absorber and the first flow channel 210 of the condenser are used to heat the fourth medium in sequence. For example, the fourth medium flows into the first flow channel 410 of the absorber and is heated by the second flow channel 420 of the absorber, and then flows into the first flow channel 210 of the condenser and is heated by the second flow channel 220 of the condenser.
[0057] In this embodiment, the generator 100, condenser 200, evaporator 300, and absorber 400 form a heat pump structure. A third medium is formed by evaporation in the second flow channel 120 of the generator 100, condensed in the second flow channel 220 of the condenser 200, and then transported to the second flow channel 320 of the evaporator 300 for further evaporation. The evaporated third medium is then transported to the second flow channel 420 of the absorber 400 for absorption by the second medium solution. A large amount of heat is released when the third medium is absorbed by the second medium solution in the absorber 400 and when it is condensed in the condenser 200. A fourth medium, such as fresh air, undergoes secondary heat absorption through the first flow channel 410 of the absorber and the first flow channel 210 of the condenser, forming a high-temperature fourth medium that can be used in the regeneration area of the impeller 700 to restore its moisture absorption function.
[0058] Optionally, the first medium includes high-temperature steam or other high-temperature media; a small amount of high-temperature steam is used to heat the second medium solution in the second flow channel 120 of the generator within the generator 100.
[0059] Optionally, the second medium solution includes lithium bromide solution, ammonia, calcium chloride solution, or lithium chloride solution or other solutions, and correspondingly, the third medium is water.
[0060] Optionally, the fourth medium may include fresh air or other media.
[0061] The rotary dehumidifier and regeneration device described in this embodiment includes a generator 100, a condenser 200, an evaporator 300, and an absorber 400. A second medium solution in the second flow channel 120 of the generator is heated by a first medium in the first flow channel 110 of the generator, causing at least a portion of the solvent in the second medium solution to evaporate and form a third medium, which is then conveyed to the second flow channel 220 of the condenser. In the condenser 200, after heat exchange between the third medium in the second flow channel 220 and the fourth medium in the first flow channel 210 of the condenser, the third medium condenses and releases a large amount of heat, simultaneously heating the fourth medium. The condensed third medium is then sent to… The first medium enters the second flow channel 320 of the evaporator 300, evaporates within the second flow channel 320, and is then transported to the second flow channel 420 of the absorber 400 for absorption by the second medium solution within the second flow channel 420. During absorption, the second medium solution releases a large amount of heat. The fourth medium exchanges heat with the second medium solution in the second flow channel 420 of the absorber in the first flow channel 410 and is heated. It is then transported to the first flow channel 210 of the condenser for further heating. This reheated fourth medium can be transported to the regeneration area of the rotor 700 to restore its moisture absorption function. This rotor dehumidification and regeneration device, through the inflow of a small amount of the first medium and the heat pump structure formed by the generator 100, condenser 200, evaporator 300, and absorber 400, can generate a large amount of high-temperature fourth medium to restore the moisture absorption function of the rotor 700. Its power consumption is relatively low, effectively solving the technical problem of high power consumption caused by the need for a compressor in existing heat pump systems that generate high-temperature air.
[0062] See Figure 3 As shown, in the optional scheme of this embodiment, the outlet of the first flow channel 210 of the condenser is connected to the inlet of the first flow channel 310 of the evaporator, that is, the fourth medium recovers a part of the heat energy in the first flow channel 310 of the evaporator 300, which further improves the heat energy utilization efficiency of the rotary dehumidification and regeneration device.
[0063] See Figures 2-5As shown, in an optional embodiment, the generator 100 further includes a second flow channel inlet 121, a second flow channel first outlet 122, and a second flow channel second outlet 123; the second flow channel inlet 121, the second flow channel first outlet 122, and the second flow channel second outlet 123 are all connected to the second flow channel 120. Optionally, the absorber 400 further includes a second flow channel first inlet 421, a second flow channel second inlet 422, and an absorber second flow channel outlet 423; the second flow channel first inlet 421, the second flow channel second inlet 422, and the absorber second flow channel outlet 423 are all connected to the second flow channel 420. Optionally, the first outlet 122 of the second flow channel of the generator, the second inlet 422 of the second flow channel of the absorber, the outlet 423 of the second flow channel of the absorber, and the inlet 121 of the second flow channel of the generator are connected in sequence and configured to circulate the second medium solution so that the second medium solution circulates between the generator 100 and the absorber 400; Optionally, the second outlet 123 of the second flow channel of the generator is configured to discharge the third medium, and the first inlet 421 of the second flow channel of the absorber is configured to flow into the third medium.
[0064] See Figure 1 As shown, in the optional embodiment, the rotary dehumidification and regeneration device further includes a heat exchanger 500; the heat exchanger 500 includes independently configured first heat exchanger channel 510 and second heat exchanger channel 520, that is, the first heat exchanger channel 510 and the second heat exchanger channel 520 are not interconnected within the heat exchanger 500. The first outlet 122 of the generator second channel and the second inlet 422 of the absorber second channel are respectively connected to the first heat exchanger channel 510, that is, the generator 100 delivers the second medium solution to the absorber 400 through the first heat exchanger channel 510; the outlet 423 of the absorber second channel and the inlet 121 of the generator second channel are respectively connected to the second heat exchanger channel 520, that is, the absorber 400 delivers the second medium solution to the generator 100 through the second heat exchanger channel 520. The heat exchanger 500 enables heat exchange between the second medium solution supplied by the generator 100 to the absorber 400 and the second medium solution supplied by the absorber 400 to the generator 100, which helps to improve the utilization rate of heat.
[0065] To improve the circulation of the second medium solution between the generator 100 and the absorber 400, a circulation pump 130 may be installed. For example, a circulation pump 130 may be installed on the pipeline between the first outlet 122 of the second flow channel of the generator and the second inlet 422 of the second flow channel of the absorber; or, a circulation pump 130 may be installed on the pipeline between the outlet 423 of the second flow channel of the absorber and the inlet 121 of the second flow channel of the generator; or, a circulation pump 130 may be installed on the pipeline between the first outlet 122 of the second flow channel of the generator and the second inlet 422 of the second flow channel of the absorber, as well as on the pipeline between the outlet 423 of the second flow channel of the absorber and the inlet 121 of the second flow channel of the generator.
[0066] See Figure 1 and Figure 6 As shown, in an optional embodiment, the evaporator 300 includes a spray pipe 330, a coil 340, and a booster pump 350. The coil 340 is located below the spray pipe 330. The inlet of the booster pump 350 is connected to the bottom of the evaporator 300, and the outlet of the booster pump 350 is connected to the spray pipe 330. The inside of the coil 340 forms the first flow channel 310 of the evaporator, and the outside of the coil 340 forms the second flow channel 320 of the evaporator. Through the spray pipe 330, the coil 340, and the booster pump 350, the evaporation of the third medium in the second flow channel 320 of the evaporator and the partial recovery of heat energy of the fourth medium in the first flow channel 310 of the evaporator are achieved.
[0067] Optionally, the evaporator 300 includes a third medium inlet 321, a third medium outlet 322, and a circulation port 323; the third medium inlet 321, the third medium outlet 322, and the circulation port 323 are respectively connected to the second flow channel 320 of the evaporator. Optionally, the third medium inlet 321 and the third medium outlet 322 are located at the top of the evaporator 300 to facilitate the flow of the third medium; optionally, the circulation port 323 is located at the bottom of the evaporator 300 and is connected to the inlet of the booster pump 350 to facilitate the spraying of the third medium onto the coil 340 for evaporation.
[0068] See Figure 1 As shown, in the optional embodiment, a throttling element 600 is connected between the second flow channel 220 of the condenser and the second flow channel 320 of the evaporator. Through the throttling element 600, the third medium from the second flow channel 220 of the condenser is throttled and depressurized, so that it becomes a low-temperature and low-pressure "gas-liquid two-phase" state, creating conditions for the third medium to absorb heat and evaporate in the second flow channel 320 of the evaporator.
[0069] See Figures 2-5As shown, this embodiment also provides a rotary dehumidification and regeneration system, including a rotary wheel 700 and the rotary dehumidification and regeneration device described in any of the above embodiments; the outlet of the first flow channel 210 of the condenser is connected to the regeneration area of the rotary wheel 700, and is used to heat the regeneration area of the rotary wheel 700 so that the rotary wheel 700 can restore its moisture absorption function.
[0070] In the optional embodiment, the first flow channel 210 of the condenser, the regeneration area of the impeller 700, and the first flow channel 310 of the evaporator are connected in sequence. That is, the impeller 700 is located between the first flow channel 210 of the condenser and the first flow channel 310 of the evaporator. This is beneficial because after the high-temperature fourth medium heats the regeneration area of the impeller 700, part of the residual heat of the fourth medium can be recovered in the first flow channel 310 of the evaporator, which further improves the efficiency of heat energy utilization.
[0071] In this embodiment, the rotary dehumidification and regeneration system heats the second medium solution in the second flow channel 120 of the generator with the first medium in the first flow channel 110 of the generator, causing at least a portion of the solvent in the second medium solution to evaporate and form a third medium, which is then transported to the second flow channel 220 of the condenser. In the condenser 200, after the third medium in the second flow channel 220 of the condenser exchanges heat with the fourth medium in the first flow channel 210 of the condenser, the third medium condenses and releases a large amount of heat, simultaneously heating the fourth medium. The condensed third medium is then sent to the second flow channel of the evaporator 300. 320, evaporates in the second flow channel 320 of the evaporator and is transported to the second flow channel 420 of the absorber 400 for absorption by the second medium solution in the second flow channel 420. The second medium solution releases a large amount of heat during absorption. The fourth medium exchanges heat with the second medium solution in the second flow channel 420 of the absorber in the first flow channel 410 and is heated. It is then transported to the first flow channel 210 of the condenser for reheating. The reheated fourth medium can be transported to the regeneration area of the rotor 700 to restore the rotor 700's moisture absorption function. This rotor dehumidification and regeneration system, through the inflow of a small amount of the first medium and the heat pump structure formed by the generator 100, condenser 200, evaporator 300, and absorber 400, can generate a large amount of high-temperature fourth medium to restore the rotor 700's moisture absorption function. Its power consumption is relatively low, effectively solving the technical problem of high power consumption caused by the need for compressors in existing heat pump systems that generate high-temperature air.
[0072] The rotary dehumidifier and regeneration system provided in this embodiment includes the aforementioned rotary dehumidifier and regeneration device. The technical features of the disclosed rotary dehumidifier and regeneration device are also applicable to this rotary dehumidifier and regeneration system, and the technical features of the disclosed rotary dehumidifier and regeneration device will not be described again. The rotary dehumidifier and regeneration system in this embodiment has the advantages of the aforementioned rotary dehumidifier and regeneration device, and the advantages of the disclosed rotary dehumidifier and regeneration device will not be described again here.
[0073] To better understand this embodiment, the following example illustrates the rotary dehumidification and regeneration device and system of this embodiment. For example, the first medium is high-temperature steam, the second medium solution is lithium bromide solution, the third medium is water, and the fourth medium is fresh air.
[0074] The first medium, using high-temperature steam at pressure P1 and temperature T1 as the driving heat source, is delivered to the first flow channel 110 of the generator 100 to heat the second flow channel 120 of the generator to a temperature of T2 and a concentration of X2. 、 A dilute lithium bromide solution with a mass of m2 (i.e., the second medium) is used to generate a solution with a temperature of T3 and a concentration of X3. 、 A refrigerant vapor (i.e., the third medium) with a mass of m3 enters the second flow channel 220 of the condenser 200, at a temperature of T4 and a concentration of X4. 、 A concentrated lithium bromide solution (i.e., the second medium) with a mass of m4 enters the second flow channel 420 of absorber 400. The heat provided by the high-temperature steam is denoted as Q. h .
[0075] After the refrigerant vapor (i.e., the third medium) enters the second flow channel 220 of the condenser 200, it exchanges heat with the medium-temperature air (i.e., the fourth medium) in the first flow channel 210 of the condenser. The refrigerant vapor begins to condense to form refrigerant water, releasing a large amount of heat during the condensation process. The heat released during the condensation process is denoted as Q. f The medium-temperature air is heated to T5℃ and then sent into the regeneration zone of the rotor 700 for desorption.
[0076] The condensed refrigerant water (i.e., the third medium) is depressurized by the throttling element 600 and then enters the second evaporator channel 320 of the evaporator 300. The refrigerant water entering the evaporator 300 is pressurized by the booster pump 350 and sprayed onto the coil 340 of the evaporator 300 to accelerate the evaporation of the refrigerant water. During the evaporation process, the refrigerant water absorbs the heat from the medium-temperature regeneration exhaust air (i.e., the fourth medium) inside the coil 340 (where the inside of the coil 340 is the first evaporator channel 310 and the outside of the coil 340 is the second evaporator channel 320) and forms refrigerant vapor (i.e., the third medium) in the second evaporator channel 320, which is then sent into the second absorber channel 420 of the absorber 400.
[0077] After the refrigerant vapor (i.e., the third medium) enters the second flow channel 420 of the absorber 400, it is absorbed by the concentrated lithium bromide solution. During the absorption process, a large amount of heat is released, which is denoted as Q. xFresh air (the fourth medium) is delivered to the first flow channel 410 of the absorber 400. The fresh air exchanges heat with the lithium bromide solution in the second flow channel 420 of the absorber and is heated to T6℃ to form medium-temperature air. The medium-temperature air is then sent to the first flow channel 210 of the condenser 200 for secondary heating.
[0078] The energy efficiency ratio (COP) of the rotary dehumidification and regeneration device and its system is (Q) f +Q x ) / Q h =1.5-2.5.
[0079] To address the issue of high power consumption associated with compressors currently on the market, the aforementioned rotary dehumidification and regeneration device and system use a small amount of high-temperature steam as the driving heat source. It utilizes the circulating flow of lithium bromide solution to achieve heat transfer and transmission, eliminating the need for a compressor. Only a circulating pump and a booster pump are required for delivery, resulting in minimal power consumption. This makes it suitable for use in areas where steam prices are low and electricity prices are high. It saves energy without significantly increasing power consumption, filling the technological gap in the market where energy-saving technology does not necessarily save electricity. Specifically, after the lithium bromide solution is heated by high-temperature steam in the generator, the water in the solution continuously vaporizes. As the water continues to vaporize, the concentration of the lithium bromide solution in the generator continuously increases. The lithium bromide solution with increased concentration enters the absorber, while the water vapor enters the condenser. In the condenser, the water vapor condenses and releases heat upon encountering fresh air, becoming high-pressure, low-temperature liquid water. Simultaneously, the medium-temperature air is heated to high-temperature air. When the water in the condenser enters the evaporator through the throttling element, it rapidly expands and vaporizes, absorbing a large amount of heat from the medium-temperature regeneration exhaust air in the evaporator (the high-temperature air becomes medium-temperature regeneration exhaust air after passing through the regeneration area of the rotor). During this process, the low-temperature water vapor enters the absorber, where it is absorbed and released heat by the lithium bromide solution, heating the fresh air in the absorber to form medium-temperature air. This medium-temperature air is then sent to the condenser and heated to high-temperature air, which is then delivered to the regeneration area of the rotor to restore the rotor's moisture absorption function. At the same time, the low-temperature water vapor enters the absorber, causing the concentration of the lithium bromide solution to gradually decrease, and then it is returned to the generator by the circulation pump, completing the entire cycle. This cycle continues endlessly, continuously heating the fresh air.
