Description

Technical Field

[0001] The invention relates to the technical field of rotary dehumidification, in particular to a rotary dehumidification device with heat circulation. Background Art

[0002] In industrial production environments with low humidity requirements, rotary dehumidifiers are generally used to achieve dehumidification. The rotor of the rotary dehumidifier is divided into a dehumidification zone and a regeneration zone. The air that needs to be dehumidified is driven by a fan through the dehumidification zone. The moisture in the air is adsorbed by the desiccant in the dehumidification zone, thereby obtaining a dry airflow with a low relative humidity, achieving the purpose of dehumidification. At the same time, the regenerated air is heated and then passed through the regeneration zone of the rotor in the reverse direction, absorbing the moisture in the desiccant and taking it away, thereby restoring the desiccant's moisture absorption capacity.

[0003] Traditional rotary dehumidifiers have at least two sets of externally connected pipes, which greatly increases the cost of laying pipes for the entire device. At the same time, in order to increase the rate of water loss in the regeneration area of ​​the rotary dehumidifier, the heat required by the rotary dehumidifier mainly comes from heating methods such as electric heating, steam heating, gas heating, and industrial waste heat. Electric heating has low cost and is easy to maintain, making it the choice of many rotary dehumidifiers. However, since a large amount of heat in electric heating is lost with the flow of gas, it is relatively wasteful and cannot be fully utilized.

[0004] To this end, we propose a heat cycle rotary dehumidification device. Summary of the Invention

[0005] The present invention aims to heat the liquid by means of a heating disk, utilizing the liquid's large specific heat capacity to minimize heat loss, thereby resolving the significant heat loss problem associated with conventional resistance wire heating. Furthermore, the invention recycles the liquid in the rotor, reducing piping costs within the rotor device and making the entire rotor dehumidification device more energy-efficient and environmentally friendly.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A heat circulation rotary dehumidification device comprises a housing and a toothed chain, wherein a motor is fixed to the bottom inner wall of the housing via bolts, a housing is fixed to the bottom inner wall of the housing via bolts, and a rotary wheel is movably connected to the housing via a bearing;

[0008] A regeneration air outlet pipe is fixed to the inner wall of one side of the box body by bolts, and one end of the regeneration air outlet pipe is in conflict with the runner. A regeneration air inlet pipe is fixed to the inner wall of one side of the box body on the other side of the runner, and a dust removal mechanism is installed in the regeneration air inlet pipe.

[0009] A sealing box is fixed to the inner wall of one side of the air outlet pipe by spot welding, and a liquid receiving chamber is fixed to one side of the sealing box by spot welding, a high-temperature box is fixed to one side of the liquid receiving chamber by spot welding, a second water pump is fixed to the bottom inner wall of the sealing box by bolts, and one end of the second water pump passes through one side of the liquid receiving chamber and is connected to a liquid extraction head, one side of the second water pump is connected to a condenser, and one end of the condenser passes through the top of the sealing box and is fixed to the inner wall of the regeneration air outlet pipe by adhesion, and the other end of the condenser is connected to the top of the liquid receiving chamber.

[0010] Furthermore, a blower is installed in the regeneration air inlet pipe, and the dust removal mechanism includes an annular sleeve, a fan, a screen, a circular slide and a scraper. The inner wall of the regeneration air inlet pipe is fixed with an annular sleeve by spot welding, and the fan is movably connected to the annular sleeve through a bearing. A circular slide is provided on the side of the annular sleeve away from the blower, and one side of the circular slide is fixed with the fan. A screen is installed on the side of the annular sleeve away from the blower, and one side of the screen is slidably connected with a scraper, and one side of the scraper passes through the circular slide and is fixed to one side of the fan.

[0011] Furthermore, a first water pump is fixed to the inner wall of one side of the regeneration outlet pipe by bolts, and one end of the first water pump passes through one side of the high-temperature box and extends into the high-temperature box. A heating plate is installed on the bottom inner wall of the high-temperature box, and a pressure relief pipe is connected to the top of the high-temperature box. A liquid guide tube is installed on one side of the liquid collecting chamber, and one end of the liquid guide tube is connected to the high-temperature box.

[0012] Furthermore, the liquid outlet end of the first water pump is connected to a heat conduction pipe, and a pipe coil is installed on the inner wall of the regeneration outlet pipe. One end of the heat conduction pipe passes through one side of the regeneration outlet pipe and is fixed to the surface of the pipe coil by adhesion, and the other end of the heat conduction pipe is connected to the top of the high-temperature box.

[0013] Furthermore, a pressure relief head is installed on the top of the box, and one side of the pressure relief head is connected to the pressure relief pipe. The bottom of one side of the box is connected to the original air pipe, and a dust blocking net is installed in the original air pipe.

[0014] Furthermore, a through hole is provided at the top of the liquid receiving chamber and at the bottom of the condenser tube, and the output end of the motor is connected to the outer wall of the rotating wheel through a gear chain.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, the temperature of the aqueous solution is increased by the heating plate in the high-temperature box, and the high-temperature aqueous solution is pumped into the heat-conducting pipe by the first water pump. At this time, the high-temperature aqueous solution moves along the heat-conducting pipe to the position of the tube disk, and the blower blows the high temperature on the surface of the heat-conducting pipe to the regeneration area of ​​the rotor, so that the water liquid in the rotor is discharged into the regeneration outlet pipe along with the high-temperature airflow. At this time, the high-temperature airflow is mixed with a lot of water vapor. When the high-temperature water vapor is pre-cooled and liquefied, the temperature of the high-temperature airflow in the regeneration outlet pipe drops. At the same time, the water vapor in the airflow liquefies and enters the liquid receiving chamber for storage through the condenser pipe. The aqueous solution in the heat-conducting pipe circulates once, and the temperature drops and returns to the high-temperature box for storage, thereby realizing partial recovery of heat energy. Compared with blowing the high temperature on the electric heating network directly to the rotor, energy consumption is greatly reduced. The moisture in the regeneration area of ​​the rotor is then recycled through the condenser pipe, and the second water pump recycles the liquid in the liquid receiving chamber. The liquid in the liquid receiving chamber can also be provided to the first water pump for use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-8 , the present invention provides a technical solution:

[0028] Example 1:

[0029] The entire dehumidification device, consisting of a rotor 4, is divided into a dehumidification zone and a regeneration zone. The rotor 4 in the dehumidification zone absorbs moisture from the flowing air in the original air pipe 7. Simultaneously, the motor 2 in the housing 1 drives the rotor 4 in the entire housing 3 to rotate continuously via the gear chain 26. When the rotor 4 moves from the dehumidification zone to the regeneration zone, the blower 11 blows the heated air onto the rotor 4. The high-temperature airflow removes moisture from the regeneration zone, allowing the rotor 4 to continue its dehumidification cycle.

[0030] like Figure 3 As shown, the present invention adopts a water bath heating method to continuously circulate the high-temperature aqueous solution through a water pump. At the same time, the specific heat capacity of the aqueous solution is large. When the high-temperature aqueous solution circulates in the heat pipe 13, less heat is dissipated and less energy is lost. Compared with directly blowing out the high temperature on the electric heating network or resistance wire, energy loss is serious, and the high-temperature and high-humidity air flow blown out is not fully utilized.

[0031] The regeneration area of ​​the entire rotor 4 device corresponds to the regeneration outlet pipe 5 and the regeneration inlet pipe 6. The regeneration outlet pipe 5 is divided into two groups of areas. The first group is the high-temperature box 15 area for heat circulation. The first water pump 14 in the sealing box 20 pumps the high-temperature aqueous solution in the high-temperature box 15 into the heat pipe 13. The heat pipe 13 passes through the regeneration outlet pipe 5 and enters the regeneration inlet pipe 6. It is fixed on the pipe coil 12 by continuously rotating. Figure 8As shown, the fixed tube coil 12 further increases the contact area between the gas in the regeneration inlet pipe 6 and the heat pipe 13. Furthermore, the entire heat pipe 13 at the tube coil 12 is made of copper, which has a higher thermal conductivity. The air temperature at the heat pipe 13 increases, and the blower 11 blows the high-temperature gas onto the runner 4. The moisture on the runner 4 also flows into the regeneration outlet pipe 5 along with the high-temperature airflow.

[0032] The second group is a heat recovery area. A winding condenser pipe 24 is installed in the regeneration outlet pipe 5. At the same time, the second water pump 19 pumps the low-temperature liquid in the liquid receiving chamber 18 into the condenser pipe 24 for continuous circulation. When the high-temperature and high-humidity airflow flows out of the runner 4, the high-humidity gas will liquefy on the surface of the condenser pipe 24 after encountering the low-temperature condenser pipe 24, and the liquefaction dissipates heat. At the same time, the dripping water droplets flow along the condenser pipe 24 into the through hole 22, and the liquid flows along the through hole 22 into the liquid receiving chamber 18 again for storage. At this time, the airflow flowing out of the regeneration outlet pipe 5 is low-temperature and low-humidity. The staff can discharge the low-temperature and low-humidity gas in the regeneration outlet pipe 5 into the humid space, thereby further reducing the humidity in the humid space. At the same time, the humidity of the gas with heavy moisture entering from the original air pipe 7 is greatly reduced after dehumidification by the runner 4, and is discharged from the treatment pipe 9;

[0033] The humidity of the gas in the entire treatment pipe 9 is low, and the humidity of the gas in the regeneration outlet pipe 5 is also low. Therefore, the two pipes can be processed in parallel, thereby increasing the gas flow rate of the entire wheel 4 dehumidification device and reducing the cost of laying pipes when installing the wheel 4 dehumidification device.

[0034] Example 2:

[0035] Since the liquid in the high-temperature box 15 needs to be heated, a heating plate 16 is installed at the bottom of the high-temperature box 15. At the same time, when the heating plate 16 heats the liquid, some water vapor will be generated. The generated water vapor will cause the liquid in the high-temperature box 15 to decrease. In order to prevent the liquid in the high-temperature box 15 from evaporating, a liquid guide tube 23 is connected between the liquid collecting chamber 18 and the high-temperature box 15. When the liquid in the liquid collecting chamber 18 continues to rise, when the liquid reaches a certain height, it will enter the high-temperature box 15 along the liquid guide tube 23 to replenish the evaporated liquid in the high-temperature box 15. The evaporated water vapor follows the pressure relief pipe 17 to the position of the pressure relief head 25 and is discharged from the pressure relief head 25. The entire first water pump 14 and the second water pump 19 are both equipped with a liquid extraction head 21 at the pumping end;

[0036] In order to prevent dust from entering the rotor 4 along the original air pipe 7 and the regeneration air inlet pipe 6, causing the dust to stick to the rotor 4 and affect the dehumidification function of the rotor 4, a dust blocking net 8 is installed on the original air pipe 7. Since the original air pipe 7 is at the joint position, the dust blocking net 8 is easier to clean, and the dust removal mechanism 10 installed on the regeneration air inlet pipe 6 is mainly for the parts that are not easy to clean. When the blower 11 starts working, air flows in the regeneration air inlet pipe 6. At this time, Figure 6 As shown, the entire dust removal mechanism 10 includes an annular sleeve 101, on which a freely rotating fan 102 is installed. When air flows in the regeneration air inlet pipe 6, the fan 102 will be driven to rotate. At the same time, a circular slide 103 is installed on the fan 102. The entire circular slide 103 blocks the gap left on the screen 105. At the same time, a scraper 104 is installed on the circular slide 103. When the fan 102 starts to rotate, the fan 102 drives the scraper 104 to roll on the screen 105 and scrape off the dust on the screen 105 to prevent dust from clogging the screen 105 and affecting the normal flow of air in the regeneration air inlet pipe 6.
