Description

Technical Field

[0001] This invention relates to the field of industrial air handling equipment, and more particularly to an energy-saving industrial dehumidifier and dryer. Background Technology

[0002] In industries such as chemical engineering, food processing, and pharmaceuticals, moisture separation is a core step in production processes, requiring efficient removal of moisture from air or gases to meet the needs of raw material drying, equipment corrosion prevention, and product quality control. Currently, condensing gas-liquid separators are widely used in industry. These separators achieve phase change separation of humid air through a compressor refrigeration cycle: water vapor condenses into liquid on the surface of a low-temperature evaporator and is then discharged through a drainage system, completing the physical separation of the gaseous medium and liquid water. These devices are widely used due to their compact structure and high separation efficiency.

[0003] Traditional equipment uses a compressor to drive the refrigerant cycle. The refrigerant absorbs heat and vaporizes in the evaporator, causing the temperature of the humid air flowing through it to drop sharply below the dew point. Water vapor condenses into liquid water droplets on the evaporator fins. Subsequently, the refrigerant is pressurized by the compressor and enters the condenser, where it releases heat and liquefies, simultaneously heating the dried air to reduce relative humidity. Essentially, this process achieves moisture separation through a gas-liquid phase change, relying on the heat exchange interface between the evaporator and condenser to capture moisture and recover energy.

[0004] The key problem with current technology lies in the condensate retention effect: water droplets generated during the separation process easily adhere to the surfaces of the evaporator and condenser, forming a liquid film layer that impedes heat transfer, leading to a significant decrease in heat exchange efficiency. As operating time increases, the performance of the separation interface continuously deteriorates, reducing the dehumidification capacity per unit of energy consumption. To maintain separation efficiency, additional equipment or forced high-load operation of the system is required, causing a surge in energy consumption. Furthermore, liquid film accumulation may induce microbial growth or corrosion of metal components, further shortening equipment lifespan. These problems severely restrict the energy efficiency and industrial applicability of condensation gas-liquid separation technology. Summary of the Invention

[0005] To overcome the drawbacks of energy efficiency reduction caused by condensation and the impact on gas-liquid separation, this invention provides an energy-saving industrial dehumidifier and dryer, aiming to solve the aforementioned problems.

[0006] An energy-saving industrial dehumidifier and dryer includes a liquid distribution tank, a water storage tank connected to the bottom of the liquid distribution tank, a protective top cover connected to the top of the liquid distribution tank, an air inlet on the side of the liquid distribution tank, an air outlet on the top of the protective top cover, a compressor installed in the water storage tank, an evaporator installed in the liquid distribution tank, and an attachment sleeve. Several water outlets are located at the bottom of the liquid distribution tank, through which liquid flows into the water storage tank. A motor is installed in the liquid distribution tank, and the attachment sleeve is rotatably connected to the liquid distribution tank and encloses the evaporator. The output shaft of the motor is connected to the attachment sleeve. A liquid removal mechanism for removing the liquid film on the surface of the attachment sleeve is provided in the liquid distribution tank, and a drain assembly for draining the liquid collected within the liquid removal mechanism is provided in the liquid removal mechanism.

[0007] Furthermore, the liquid removal mechanism includes a liquid removal ring, the output shaft of the motor is connected to a drive wheel, two reciprocating screws are rotatably connected inside the liquid distribution tank, a first driven wheel is connected to the top of the reciprocating screws, the first driven wheel meshes with the drive wheel, the liquid removal ring is threadedly connected to the reciprocating screws, and a meshing plate is rotatably connected inside the liquid removal ring, the meshing plate is slidably connected to the attachment sleeve.

[0008] Furthermore, the drainage assembly includes a drainage rod, a water storage tank is formed inside the drainage ring, several T-frames are connected inside the drainage ring, the T-frames are located inside the water storage tank, the drainage rod is slidably connected to the bottom of the T-frames, a through hole is formed at the bottom of the water storage tank, the bottom of the drainage rod passes through the through hole, the T-frames and the drainage rod are jointly fitted with an elastic element, the top of the elastic element is connected to the T-frame, the bottom of the elastic element is connected to the drainage rod, and several top rods are connected to the top of the bottom plate of the liquid distribution tank, the top rods are in a pressing fit with the drainage rod.

[0009] Furthermore, it also includes a flow guiding component, which includes a diversion pipe. A liquid-gathering ring is connected inside the water storage tank. A three-way pipe is connected inside the water storage tank and connected to the bottom of the liquid-gathering ring. A support pipe is connected to the front wall of the water storage tank. A fixed sleeve is threaded to the front end of the support pipe. A clamping member is connected inside the support pipe. A connecting pipe is connected inside the clamping member. The front end of the diversion pipe is slidably connected to the support pipe and rotatably connected to the fixed sleeve. The rear end of the diversion pipe is slidably connected to the three-way pipe and has an opening at the rear end.

[0010] Furthermore, a drying plate is connected to the left side wall of the liquid separator, which is divided into upper and lower spaces. The drying plate connects the upper and lower spaces of the liquid separator. The airflow enters the lower space of the liquid separator through the air inlet, then passes through the drying plate and enters the upper space of the liquid separator, and finally exits from the air outlet.

[0011] Furthermore, the middle of the liquid distribution tank is provided with an annular inner groove that mates with the attachment sleeve, the top of the meshing plate is provided with an inclined surface, the outer edge is inclined downward and flush with the top of the water storage tank, the inner side of the meshing plate is provided with sealing rubber, and the drying plate is provided with several vertical ventilation gaps evenly distributed.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The motor drives the active wheel to mesh with the first driven wheel, which in turn drives the reciprocating screw to control the liquid removal ring to slide up and down. This allows the meshing plate to stick tightly to the outer wall of the attachment sleeve and scrape off the condensate droplets, preventing the heat exchange interface from being covered by a water film. This ensures stable heat transfer efficiency between the refrigerant and the air, and reduces the energy efficiency degradation of the system.

[0014] 2. Through the drainage component, when the liquid removal ring is at the bottom, the drainage rod and the top rod cooperate to automatically open the drainage rod, releasing the water droplets temporarily stored in the water storage tank. When it moves upward, the elastic element resets and closes the through hole, realizing periodic drainage and preventing the droplets from sticking back.

[0015] 3. By using the clamping parts of the flow guide component and the inclined surface of the fixed sleeve to press together, the external water pipe can be quickly connected and the rear opening of the tee pipe can be sealed, so as to achieve seamless drainage switching when the water tank is full.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0027] Example: An energy-saving industrial dehumidifier and dryer, such as Figures 1-4As shown, the system includes a water storage tank 1, a liquid distribution tank 2, a protective top cover 3, a compressor 4, and an evaporator 5. The bottom of the liquid distribution tank 2 is connected to the water storage tank 1. A drain pipe with a plug is installed at the bottom of the water storage tank 1, allowing water stored in the tank to be drained. The top of the liquid distribution tank 2 is connected to the protective top cover 3. An air inlet 202 is located on the right side of the liquid distribution tank 2, and an air outlet 301 is located on the top of the protective top cover 3. The compressor 4 is installed inside the water storage tank 1, which encloses it. The water collected in the tank cools the compressor 4. The liquid distribution tank 2 also includes an attachment sleeve 6, a motor 7, a liquid removal mechanism 8, and a drainage assembly 9. Several water outlets 201 are located at the bottom of the liquid distribution tank 2, through which liquid flows into the water storage tank 1. The motor is installed inside the liquid distribution tank 2. 7. A controller is installed on the rear side of the water storage tank 1. The controller is wired to the compressor 4, evaporator 5 and motor 7. The attachment sleeve 6 is rotatably connected to the liquid distribution tank 2. The middle of the liquid distribution tank 2 is fitted with an annular inner groove to match the attachment sleeve 6. That is, the distance between the outer wall of the annular inner groove of the liquid distribution tank 2 and the attachment sleeve 6 is equal. The attachment sleeve 6 wraps around the evaporator 5. The surface of the attachment sleeve 6 is provided with vertical raised textures to increase the contact area between the attachment sleeve 6 and the air. The output shaft of the motor 7 is fixedly connected to the top of the attachment sleeve 6. The rotating attachment sleeve 6 continuously changes the position of its surface in contact with the airflow entering the air inlet 202 to avoid the local temperature difference of the attachment sleeve 6 affecting the condensation efficiency. The liquid distribution tank 2 is provided with a liquid removal mechanism 8 for removing the liquid film on the surface of the attachment sleeve 6. The liquid removal mechanism 8 is provided with a drain assembly 9 for draining the liquid collected in the liquid removal mechanism 8.

[0028] like Figure 2 , Figure 4 and Figure 9 As shown, the liquid removal mechanism 8 includes a driving wheel 81, a first driven wheel 82, a reciprocating screw 83, a liquid removal ring 84, and a meshing plate 85. The output shaft of the motor 7 is connected to the driving wheel 81. Two reciprocating screws 83 are rotatably connected inside the liquid distribution tank 2. The top of each reciprocating screw 83 is connected to a first driven wheel 82. The two first driven wheels 82 mesh with the driving wheel 81 and are symmetrical along the diameter of the driving wheel 81. The liquid removal ring 84 is threadedly connected to the reciprocating screw 83. The two reciprocating screws 83 jointly drive the liquid removal ring 84 to slide up and down. The meshing plate 85 is rotatably connected inside the liquid removal ring 84 through a bearing. The meshing plate 85 and the attachment sleeve 6 are slidably connected through a slider and a groove. The meshing plate 85 can move up and down relative to the attachment sleeve 6. The meshing plate 85 is in contact with the surface of the attachment sleeve 6. Sealing rubber is provided on the inner side of the meshing plate 85.

[0029] like Figures 4-6As shown, the drainage assembly 9 includes a T-frame 92, a drain rod 93, an elastic element 94, and a top rod 95. A water storage tank 91 is opened inside the drain ring 84. The top of the meshing plate 85 is provided with an inclined surface, and the outer edge slopes downward and is flush with the top of the water storage tank 91. Sixteen T-frames 92 are connected inside the drain ring 84. The T-frames 92 are located inside the water storage tank 91. The drain rod 93 is slidably connected to the bottom of the T-frame 92. A through hole is opened at the bottom of the water storage tank 91. The bottom of the drain rod 93 passes through the through hole. A rubber gasket is provided at the bottom of the drain rod 93 to ensure the sealing of the through hole at the bottom of the water storage tank 91. The T-frames 92 and the drain rod 93 are jointly fitted with the elastic element 94. The top of the elastic element 94 is connected to the T-frame 92, and the bottom of the elastic element 94 is connected to the drain rod 93. Sixteen top rods 95 are connected to the top of the bottom plate of the liquid distribution tank 2. The top rods 95 and the drain rods 93 are squeezed together.

[0030] like Figure 2 and Figure 3 As shown, it also includes an installation box 10 and a heat pipe 11. The top of the liquid distribution tank 2 is connected to the installation box 10, the middle of the heat pipe 11 is connected inside the liquid distribution tank 2, the bottom of the heat pipe 11 surrounds the motor 7, and the top of the heat pipe 11 is connected to the installation box 10 in an "S" shape to increase the contact area with the airflow and improve the heating efficiency.

[0031] like Figure 2 and Figure 4 As shown, it also includes a first transmission rod 12, a second driven wheel 13, a first bevel gear set 14, a second transmission rod 15, a second bevel gear set 16, a support rod 17, and a fan blade 18. The first transmission rod 12 is vertically rotatably connected inside the liquid separator 2. The bottom of the first transmission rod 12 is connected to the second driven wheel 13. The driving wheel 81 meshes with the second driven wheel 13. The upper part of the liquid separator 2 is horizontally rotatably connected to the second transmission rod 15. The end of the second transmission rod 15 and the top of the first transmission rod 12 are both provided with the first bevel gear set 14. The top of the liquid separator 2 is connected to three support rods 17. The fan blade 18 is rotatably connected inside the support rods 17. The bottom of the fan blade 18 is provided between the second transmission rod 15 and the second transmission rod 16. The number of teeth of the second driven wheel 13 is much smaller than the number of teeth of the driving wheel 81. After power transmission, the fan blade 18 rotates at high speed, accelerating the gas flow rate inside the liquid separator 2.

[0032] like Figure 2 , Figure 7 and Figure 8As shown, it also includes a flow guiding assembly 19, which includes a liquid-gathering ring 191, a three-way pipe 192, a support pipe 193, a clamping member 194, a connecting pipe 195, a diverting pipe 196, and a fixing sleeve 197. The liquid-gathering ring 191 is connected inside the water storage tank 1, and the three-way pipe 192 is connected inside the water storage tank 1. The three-way pipe 192 is connected to the bottom of the liquid-gathering ring 191. The support pipe 193 is fixedly connected to the front wall of the water storage tank 1. The front end of the support pipe 193 is threadedly connected to the fixing sleeve 197. The clamping member 194 is connected inside the support pipe 193. The clamping member 194 is provided with a forward-extending pressure rod, and the front end of the pressure rod is provided with an inclined surface. The inclined surface of the inner wall of the fixed sleeve 197 is pressed and engaged with the inclined surface of the front end of the clamping member 194, pushing the pressure rod of the clamping member 194 to bend inward and clamp the external water pipe. Thus, the clamping member 194 is pressed and engaged with the external water pipe. The clamping member 194 is connected to the connecting pipe 195. The front end of the diversion pipe 196 is slidably connected to the support pipe 193, and the diversion pipe 196 is rotatably connected to the fixed sleeve 197. The rear end of the diversion pipe 196 is slidably connected to the tee pipe 192. The rear end of the diversion pipe 196 has a sealing structure, and an opening is provided on the upper side of the rear end of the diversion pipe 196, so that water flows forward after entering the diversion pipe through the tee pipe and the opening.

[0033] like Figure 2 and Figure 3 As shown, it also includes a drying plate 20. The left side wall of the liquid separator 2 is connected to the drying plate 20 by bolts. The drying plate 20 is replaced after a period of use. The liquid separator 2 is divided into upper and lower spaces. The drying plate 20 connects the upper and lower spaces of the liquid separator 2. The airflow enters the lower space of the liquid separator 2 through the air inlet 202, then passes through the drying plate 20 and enters the upper space of the liquid separator 2, and finally exits from the air outlet 301. The drying plate 20 is evenly provided with several vertical ventilation gaps.

[0034] Air enters through inlet 202, passes through attachment sleeve 6, and then enters the drying plate 20. It then flows upwards along the pipes inside the liquid separator 2, is accelerated by fan blades 18, passes through heat pipe 11, and finally exits from outlet 301, achieving gas-liquid separation. Operators start and stop compressor 4, evaporator 5, and motor 7 via controller. When the dryer is turned on, compressor 4 and evaporator 5 start, lowering the temperature inside attachment sleeve 6 and liquefying the moisture in the passing gas. The liquefied water droplets adhere to the surface of attachment sleeve 6. At this time, motor 7 is started via controller, causing attachment sleeve 6 to rotate, ensuring uniform contact between the surface of attachment sleeve 6 and the air, guaranteeing effective airflow contact. At the same time, the motor 7 drives the drive wheel 81 to rotate, and the drive wheel 81 drives the two first driven wheels 82 to rotate, thereby driving the reciprocating screw 83 to rotate. The reciprocating screw 83 drives the liquid removal ring 84, which is threaded to it, to move downward. The meshing plate 85 inside the liquid removal ring 84 slides along the outer side of the attachment sleeve 6 to scrape off the water droplets on the surface of the attachment sleeve 6. As the attachment sleeve 6 rotates, the meshing plate 85 also rotates. The scraped water droplets fall into the bottom of the liquid distribution tank 2 and flow into the water storage tank 1 through the water outlet 201.

[0035] For temporary use, the water tank 1 can be used to collect the separated water droplets. After use, the water can be drained through the drain pipe at the bottom. If long-term use is required, an external drain pipe is needed to drain the separated water into the city drainage pipe. The water through the outlet hole 201 is collected by the liquid collection ring 191 and guided to the three-way pipe 192. The water then flows into the water tank 1 through the opening at the rear end of the three-way pipe 192. However, as the working time increases, the water collected in the water storage tank 1 gradually increases, and the water in the water storage tank 1 cannot be drained in time during operation. At this time, the external water pipe is passed through the fixed sleeve 197 and fitted onto the connecting pipe 195, and pushed backward. After the external water pipe is fitted, the fixed sleeve 197 is tightened. The fixed sleeve 197 is threaded to the support pipe 193. During the backward movement, it pushes the diversion pipe 196 to slide backward. After the opening at the top of the diversion pipe 196 is connected to the top pipe of the support pipe 193, the rear end of the diversion pipe 196 closes the rear opening of the tee pipe 192, and the water flows out along the diversion pipe 196. Moreover, as the fixed sleeve 197 is tightened, the fixed sleeve 197 is threaded to the support pipe 193 and squeezed into the clamping member 194. The external water pipe is fixed by the pressure rod of the clamping member 194 to prevent liquid leakage. After use, loosen the fixing sleeve 197, and the clamp 194 will disengage from the external water pipe. While loosening the fixing sleeve 197, pull the diversion pipe 196 forward to slide back to its original position, so that the diversion pipe 196 closes the front opening of the three-way pipe 192. At this time, water can be collected and guided through the liquid collection ring 191 to the three-way pipe 192 and then flow into the water storage tank 1 from the rear opening for collection.

[0036] When the meshing plate 85 scrapes water droplets downwards, the droplets fall directly into the bottom of the liquid distribution tank 2. When the meshing plate 85 scrapes water droplets upwards, the water enters the water storage tank 91 along the top slope of the meshing plate 85. Specifically, when the reciprocating screw 83 drives the liquid removal ring 84 to slide upwards, the water droplets scraped by the meshing plate 85 flow into the water storage tank 91, and the drain rod 93 seals the water storage tank 91 through the bottom rubber gasket. When the liquid removal ring 84 moves downwards, the drain rod 93 moves downwards along with the liquid removal ring 84. The bottom of the drain rod 93 is pressed against the top rod 95, thereby the top rod 95 lifts the drain rod 93, compressing the elastic element 94, and the drain rod 93 slides upwards along the T-frame 92. Since the diameter of the top rod 95 is much smaller than the through hole at the bottom of the water storage tank 91, the water collected in the water storage tank 91 flows out from the through hole and flows into the liquid collection ring 191 through the water outlet 201. When the liquid removal ring 84 moves upward, the elastic element 94 rebounds, pushing the liquid discharge rod 93 down and resealing the through hole at the bottom of the water storage tank 91, thereby solving the problem of water droplet retention.

[0037] When the gas containing moisture passes through the drying plate 20, the multiple gaps in the drying plate 20 ensure that the gas inevitably comes into contact with the drying plate 20, thus ensuring the separation effect of moisture in the gas. Subsequently, the gas passes through the upper space of the separator 2. The driving wheel 81 drives the first transmission rod 12 to rotate through the meshing second driven wheel 13. The first transmission rod 12 drives the second transmission rod 15 through the first bevel gear set 14, and the second transmission rod 15 drives the fan blades 18 to rotate through three sets of second bevel gear sets 16, blowing the gas upwards. This is due to the pressure difference between the low-temperature gas and the high-temperature gas, and the low gas velocity when passing through the drying plate 20. The rotating fan blades 18 expel the gas, thus ensuring the efficient intake of the airflow from the air inlet 202 of the separator 2. The gas then passes through the middle of the mounting box 10. The heat generated by the motor 7 during operation is absorbed by the heat pipe 11 and then transferred to the top, heating the gas passing through the mounting box 10, restoring it to room temperature, and finally dissipating it through the air outlet 301. The filter at the air outlet 301 can prevent foreign objects from entering the protective top cover 3.

[0038] The fan blades 18 are powered by the motor 7, and the heat from the heat pipe 11 also comes from the motor 7. This saves energy while achieving the same function, and the heat absorbed by the heat pipe 11 cools the environment around the motor 7. The gas flow area surrounds the motor 7, ensuring the operating temperature of the motor 7. The water tank 1 surrounds the compressor 4, and the water collected in the water tank 1 cools the compressor 4, ensuring the equipment operates at a suitable temperature for a long time and extending its service life.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
