Description

Technical Field

[0001] The invention relates to the technical field of air dehumidification, and in particular to a high-efficiency energy-saving rotary dehumidifier suitable for low-temperature environments. Background Art

[0002] In my country, due to the diversity of climate, houses in different regions face different humidity problems. The air humidity in the humid southwest region is high all year round, and water vapor is everywhere. Although the Qinghai-Tibet Plateau has a dry climate overall, moisture is prone to accumulate in houses under certain special conditions. In the cold northern region, the temperature difference between indoor and outdoor is large in winter, and condensation water is easily generated on the surface of indoor air when it is cold, increasing indoor humidity. Coastal areas are affected by the marine climate, with high air humidity and high salt content, and excessive humidity in houses is common.

[0003] At present, the traditional air dehumidification methods are mainly refrigeration dehumidification and rotary dehumidification. The working principle of the refrigeration dehumidifier is to cool the air with the help of refrigerant circulation. When the air temperature drops below the dew point temperature, the water vapor in it will condense into liquid water and discharge, thereby achieving the purpose of dehumidification. However, this dehumidification method has obvious defects. In a low temperature environment, the surface of the evaporator of the refrigeration dehumidifier is very easy to frost. Once frosted, the heat exchange efficiency of the evaporator is greatly reduced, which will not only cause a sharp drop in dehumidification efficiency, but in severe cases, it will even cause the equipment to fail completely and cannot operate normally. For example, in winter in cold northern regions, the outdoor temperature is often below zero. When a refrigeration dehumidifier is used indoors, the evaporator will be covered with frost in a short time, and the equipment has to be defrosted frequently, which greatly affects the dehumidification effect and the normal use of the equipment.

[0004] The rotary dehumidifier uses the adsorption characteristics of the adsorbent material to dehumidify. Compared with the refrigeration dehumidifier, it is not limited by the ambient temperature and can work under various temperature conditions. However, the traditional rotary dehumidifier also has many disadvantages. Its energy consumption is high, and a large amount of electricity is consumed during operation to drive the rotation of the wheel and regenerate the adsorbent material. In addition, when the adsorbent material is regenerated, the control of the regeneration temperature is not accurate enough. If the regeneration temperature is too high, it will not only waste a lot of energy, but also may damage the performance of the adsorbent material and shorten its service life; if the regeneration temperature is too low, it will not be able to effectively remove the moisture adsorbed on the adsorbent material, resulting in poor dehumidification effect. In addition, the heat recovery efficiency of the traditional rotary dehumidifier is low. When the adsorbent material is regenerated, a large amount of heat generated cannot be fully recycled, which further increases energy consumption. In low temperature environments, such as winter in cold northern regions, the temperature difference between indoor and outdoor is large, and the energy cost is high. These problems of traditional rotary dehumidifiers are becoming more and more prominent, and it is difficult to meet people's urgent needs for efficient and energy-saving dehumidification.

[0005] Therefore, a high-efficiency and energy-saving rotary dehumidifier suitable for low-temperature environments is proposed to solve the above problems. Summary of the invention

[0016] Compared with the prior art, the present invention provides a high-efficiency and energy-saving rotary dehumidifier suitable for low-temperature environments, which has the following beneficial effects: 1. Through the setting of heat exchange, it is divided into a processing area and a regeneration area. In the processing area, the humid air is first pre-cooled in the heat exchange processing area to reduce the air temperature, and then the pre-cooled air enters the processing area of ​​the wheel. Under the coordinated operation of the compression wheel and the reduction motor, the wheel rotates to efficiently absorb water vapor in the air and dehumidify the circulating air. Combined with heat exchange for pre-cooling, it is not limited by the ambient temperature and can achieve efficient dehumidification in a low-temperature environment. The pre-cooling of heat exchange improves the adsorption efficiency of the wheel, so that the equipment can still stably and efficiently remove moisture from the air in a low-temperature environment to meet the dehumidification needs in a low-temperature environment; then the dry air is sent out by the processing fan, which effectively avoids the frosting problem of the refrigeration dehumidifier, and compared with the traditional rotary dehumidifier, the dehumidification efficiency in a low-temperature environment is significantly improved, and it can provide dry air for the room more efficiently.

[0017] 2. Through the setting of the regeneration fan, during the regeneration process, air is sucked in by the regeneration fan, heated to the set temperature by the electric heating wire, and then enters the rotor regeneration area to desorb moisture, forming high-temperature and high-humidity air. The electric heating wire is controlled by a thermostat to accurately control the regeneration temperature and avoid energy waste caused by temperature fluctuations. At the same time, the high-temperature and high-humidity air enters the regeneration area of ​​the heat exchange and exchanges heat with the ambient temperature, so that the high-temperature and high-humidity air transfers heat to the ambient cold air in the regeneration area of ​​the heat exchange, realizing energy recovery while further reducing energy consumption. Compared with traditional equipment, the energy consumption during the regeneration process is significantly reduced.

[0018] 3. Under the setting of the heating wire, the regeneration area uses a thermostat to control the constant temperature of the heating wire, accurately adjust the temperature of the regeneration air, avoid inaccurate regeneration temperature control, large temperature fluctuations, and energy waste. Through precise temperature control, ensure that the regeneration process is carried out at an appropriate temperature, avoid additional energy consumption caused by excessively high or low temperatures, make full use of energy, further reduce the energy consumption of the equipment, and improve energy utilization efficiency.

[0019] 4. After the heat exchange, the regenerated air is filtered twice through the water vapor filter, which greatly improves the stability and service life of the equipment operation, and prevents the water vapor in the regenerated air from entering the regeneration fan, causing damage to the regeneration fan and affecting the normal operation of the equipment. The secondary filtration effectively intercepts the water vapor in the regeneration air to prevent it from entering the regeneration fan, reducing the probability of regeneration fan failure, ensuring the stable operation of the equipment, extending the overall service life of the equipment, and reducing maintenance costs. At the same time, this design makes the equipment compact and easy to install, suitable for various places, and due to its low energy consumption and reasonable design of various components, the probability of failure is reduced, and the maintenance cost is also reduced, which has obvious advantages in installation and maintenance.

[0020] 5. Under the setting of storage container to fixed ring, a storage container is added between the processing areas of heat exchange, and filled with low-temperature paraffin material with phase change temperature at low temperature. When the high-temperature and high-humidity regeneration air passes through, the phase change material absorbs heat and undergoes phase change from solid to liquid to store energy; during the processing, the low-temperature and humid air passes through the module, and the phase change material releases the stored heat and changes from liquid back to solid to preheat the air. Based on the phase change energy storage and release principle of phase change material at low temperature, the energy recovery efficiency is greatly improved, energy waste is reduced, equipment energy consumption is reduced, and the energy-saving performance of the equipment in a low-temperature environment is enhanced.

A clamping wheel 17 is provided on the outer ring of the positioning pin 18, and the side of the clamping wheel 17 close to the pulley 20 is in contact with the conveyor belt 21.

[0028] The top of the double-layer placement plate in the sheet metal 1 is fixedly connected with a main board 23, a thermostat 24 is arranged on one side of the main board 23, and a transformer 25 is arranged on one side of the thermostat 24. The main board 23, the thermostat 24, and the transformer 25 are all fixedly connected to the placement plate in the sheet metal 1 by screws. The main board 23, the thermostat 24, and the transformer 25 are all electrically connected to the same controller. The main board 23 is mainly used to control the equipment and process data. The main board 23 is used as the control core and is connected to the humidity sensor 4 and the digital operation Panel 6, thermostat 24, transformer 25, the thermostat 24 is connected to the heating wire 27 and is mainly used to control the temperature of the regeneration area. The side of the rotor 22 away from the heat exchange core 12 is provided with the heating wire 27, and a cover is provided outside the heating wire 27. The heating wire 27 is mainly used to heat the regeneration air. The heating wire 27 is placed on a double-layer placement plate provided in the sheet metal 1. One side of the heating wire 27 is fixedly connected to a regeneration fan 26, and the regeneration fan 26 is mainly used to adsorb and transport the regeneration air and is connected to the regeneration air channel.

[0029] A storage container 141 is fixedly connected to one side of the heating wire 27 close to the rotating wheel 22, a ventilation pipe A 142 is fixedly connected to one side of the storage container 141, a ventilation pipe B 143 is fixedly connected to one side of the storage container 141 away from the ventilation pipe A 142, a plurality of treatment tubes 144 are fixedly connected inside the storage container 141, both ends of the treatment tubes 144 are fixedly connected to fixing rings 145, the treatment tubes 144 are fixedly connected to the storage container 141 via the fixing rings 145, the treatment tubes 144 are curved hollow tubes, and low-temperature paraffin is arranged in the storage container 141.

[0030] Everything in the above example works like this: When in use, the power cord 2 is connected to the power supply to power on the device, and the data connection line 3 is connected to the external device to transmit data. The humidity sensor 4 starts to detect the air humidity. At this time, the external low-temperature and high-humidity air enters from the front of the device, and is filtered through the air inlet filter 7 to remove impurities in the air. Then the air circulates into the processing area of ​​the heat exchange core 12. Under the action of the heat exchange core 12, the humid air is cooled, and the temperature is reduced while improving the efficiency of the subsequent adsorption process. Further, the pre-cooled humid air enters the processing area of ​​the rotor 22. The adsorption material on the rotor 22 absorbs the moisture in the air during circulation to dry the air. Then the dry air is sent out by the processing fan 16 and enters the space that needs to be dehumidified through the processing air outlet 5. When the air circulation wheel 22 is performing moisture absorption treatment, the reduction motor 19 is started, and the pressing wheel 17 is driven through the pulley 20 and the conveyor belt 21, and then the wheel 22 is driven to rotate, so as to perform maximum absorption treatment on the wet air circulating in the heat exchange core 12, thereby improving the absorption efficiency; Furthermore, the air treated after adsorption passes through the area of ​​the storage container 141 through the A ventilation pipe 142, and the cold air causes the low-temperature paraffin set in the storage container 141 to change from liquid to solid and solidify. This solidification process causes the low-temperature paraffin phase change material stored in the storage container 141 to release the stored heat and change from liquid to solid, thereby preheating the air. Please refer to the above working process Figures 1 to 5 .

[0031] When in use, the regeneration fan 26 inhales outside air, and the air enters the electric heating wire 27. After the air enters, the main board 23 controls the electric heating wire 27 to heat to the set temperature and maintain a constant temperature. Under the setting of the outer cover of the electric heating wire 27, a hot space is formed in the electric heating wire 27, and the air forms high-temperature air. The high-temperature air enters the regeneration area of ​​the rotor 22, desorbs the moisture adsorbed in the previous step in the rotor 22, and restores the adsorption capacity of the rotor 22. The high-temperature and high-humidity air generated at this time enters the space of the storage container 141 through the B ventilation pipe 143. After circulating in the inner cavity of the storage container 141, the high-temperature air prompts the solidified low-temperature paraffin phase change material in the storage container 141 to absorb heat, changing from solid to liquid, and storing thermal energy, thereby forming a cycle with the above steps, improving energy recovery efficiency, reducing energy waste, and reducing equipment energy consumption; Then the high-temperature and high-humidity air continues to enter the regeneration area of ​​the heat exchange core 12. In the heat exchange core 12, the high-temperature and high-humidity air exchanges heat with the external ambient temperature, and part of the water vapor condenses into water and is discharged through the drain port 9. The regenerated air cooled by the heat exchange core 12 is filtered for the second time through the water vapor filter 13 to remove the residual water vapor, and then passes upward through the cooling area of ​​the heat exchange core 12 for further cooling, and finally enters the regeneration fan 26 channel for internal circulation.

[0032] Through the setting of the heat exchange core 12, it is divided into a processing area and a regeneration area. In the processing area, the humid air is first pre-cooled in the processing area of ​​the heat exchange core 12 to reduce the air temperature, and then the pre-cooled air enters the processing area of ​​the wheel 22. Under the coordinated operation of the compression wheel 17 and the reduction motor 19, the wheel 22 rotates to efficiently absorb water vapor in the air and dehumidify the circulating air. Combined with the pre-cooling treatment of the heat exchange core 12, it is not limited by the ambient temperature and can achieve efficient dehumidification in a low-temperature environment. The pre-cooling of the heat exchange core 12 improves the adsorption efficiency of the wheel 22, so that the equipment can still stably and efficiently remove moisture from the air in a low-temperature environment to meet the dehumidification needs in a low-temperature environment; then the dry air is sent out by the processing fan 16, which effectively avoids the frosting problem of the refrigeration dehumidifier, and compared with the traditional rotary dehumidifier, the dehumidification efficiency in a low-temperature environment is significantly improved, and it can more efficiently provide dry air for the room.

[0033] Furthermore, through the setting of the regeneration fan 26, during the regeneration process, air is sucked in by the regeneration fan 26, heated to the set temperature by the heating wire 27, and then enters the regeneration area of ​​the wheel 22 to desorb moisture, forming high-temperature and high-humidity air. The heating wire 27 is controlled by a thermostat 24 to accurately control the regeneration temperature and avoid energy waste caused by temperature fluctuations. At the same time, the high-temperature and high-humidity air enters the regeneration area of ​​the heat exchange core 12 and exchanges heat with the ambient temperature, so that the high-temperature and high-humidity air transfers heat to the ambient cold air in the regeneration area of ​​the heat exchange core 12, thereby realizing energy recovery and further reducing energy consumption. Compared with traditional equipment, the energy consumption during the regeneration process is significantly reduced.

[0034] Under the setting of the heating wire 27, the regeneration area uses a thermostat 24 to control the constant temperature of the heating wire 27, accurately adjust the temperature of the regeneration air, avoid inaccurate regeneration temperature control, large temperature fluctuations, and energy waste. Through precise temperature control, ensure that the regeneration process is carried out at an appropriate temperature, avoid additional energy consumption caused by excessively high or low temperatures, and make full use of energy, further reduce the energy consumption of the equipment, and improve energy utilization efficiency.

[0035] After the regeneration wind passes through the heat exchange core 12, it is filtered twice through the water vapor filter 13, which greatly improves the stability and service life of the equipment operation, and prevents the water vapor in the regeneration wind from entering the regeneration fan 26, causing damage to the regeneration fan 26 and affecting the normal operation of the equipment. The secondary filtration effectively intercepts the water vapor in the regeneration wind and prevents it from entering the regeneration fan 26, reducing the probability of failure of the regeneration fan 26, ensuring the stable operation of the equipment, extending the overall service life of the equipment, and reducing maintenance costs. At the same time, this design makes the equipment compact in structure and easy to install, suitable for various places, and due to its low energy consumption and reasonable design of various components, the probability of failure is reduced, and the maintenance cost is also reduced accordingly, which has obvious advantages in installation and maintenance.

[0036] Under the setting of the storage container 141 to the fixed ring 145, a storage container 141 is added between the processing areas of the heat exchange core 12, and is filled with a low-temperature paraffin material with a phase change temperature at low temperatures. When the high-temperature and high-humidity regeneration air passes through, the phase change material absorbs heat and undergoes a phase change (from solid to liquid) to store energy; during the processing, the low-temperature and humid air passes through the module, and the phase change material releases the stored heat (from liquid back to solid) to preheat the air. Based on the phase change energy storage and release principle of the phase change material at low temperatures, the energy recovery efficiency is greatly improved, energy waste is reduced, equipment energy consumption is reduced, and the energy-saving performance of the equipment in a low-temperature environment is enhanced.
