Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air water generation, in particular to a solar-powered air water generation system and equipment. BACKGROUND

[0002] Air water generation technology, as a new water resource acquisition method, has important application value in arid and water shortage areas, field operations and emergency rescue scenes, and can directly extract water from the atmosphere to solve water shortage problems. The existing air water generation technology mainly includes thermoelectric refrigeration type and solar adsorption type. The thermoelectric refrigeration type system mainly consists of a thermoelectric refrigeration module, a heat dissipation module, an air water generation module and a collector. It utilizes the Peltier effect to drive the thermoelectric module to generate a temperature difference through direct current, so that the cold end temperature is lower than the air dew point temperature, thereby condensing the water vapor in the air into liquid water. The solar adsorption type system adopts core components such as adsorption bed, solar vacuum heat collector, condenser and water collector. It adsorbs water in the air through adsorbent, and then uses solar energy to heat and release water from the adsorbent. Finally, the water vapor is converted into liquid water through the condenser. Both of these two technical paths are designed around the basic process of "air water extraction-purification-storage", which can effectively solve the water supply demand in specific environments.

[0003] In the thermoelectric refrigeration type system, the condensation water droplets adhering to the surface of the condenser will absorb its cold energy, causing the cold end temperature to rise, affecting the condensation effect of the condenser, and causing additional energy consumption. In addition, the water film formed by the condensed water will produce thermal resistance, which will also affect the heat exchange efficiency and condensation effect of the condenser, further affecting the overall performance of the system.

[0026] The solar-powered air-to-water device of the present application further comprises a support 104, and the box 101 is arranged on the support 104. One side of the box 101 is provided with a box door for facilitating maintenance and repair. The adsorption bed 103 comprises a bed body and an adsorbent. The bed body is usually made of corrosion-resistant metal materials such as stainless steel and aluminum alloy to withstand temperature changes and humidity erosion during the circulation process. The adsorbent can be silica gel, zeolite molecular sieve, activated alumina or metal organic framework material, etc. The adsorbent is filled in the bed body in the form of granules, honeycombs or monolithic coating. The adsorption bed 103 can also be provided with a heat exchange / conduction structure, such as heat exchange fins, etc. The adsorption bed 103 has an air inlet end and an air outlet end. A fan is arranged on the box 101 for guiding external air into the adsorption bed 103 from the air inlet end. The adsorbent physically adsorbs water vapor molecules in the air. At this time, the adsorption bed 103 is in a water absorption state, and the adsorption capacity of the adsorption bed 103 decreases until it cannot continue to adsorb. When the heated air in the inner cavity is delivered to the adsorption bed 103, the van der Waals force between the adsorbent and the water molecules is weakened, and the water molecules are separated from the surface of the adsorbent. At this time, the adsorption bed 103 is in a water release state. The structure and working principle of the adsorption bed 103 described above are both prior art, and will not be described here.

[0027] The top wall of the intermediate tank 102 is provided with a through hole in the center, and the upper part of the inner cavity can communicate with one end of the adsorption bed 103 through the through hole. The lower part of the inner cylinder 201 is provided with a side hole 206, and the lower part of the inner cavity can communicate with the lower part of the side cavity through the side hole 206 to realize air circulation. The center of the spiral fin 203 forms a channel to make the inner cavity pass through up and down. The outer side of the condensing fin 204 has a gap with the inner wall of the intermediate tank 102 to make the side cavity pass through up and down. The driving part comprises a motor, and the motor is provided with a corresponding power supply and a control module to control the start and stop and operating conditions. The motor can drive the inner cylinder 201 to rotate relative to the intermediate tank 102 through a gear structure.

[0028] In one embodiment, two adsorption beds 103 are arranged, and the two adsorption beds 103 are alternately in a water absorption state and a water release state.

[0029] One of the adsorption beds 103 is in a water absorption state, and the other is in a water release state, to ensure that the device can continuously produce water.

[0030] In one embodiment, two adsorption beds 103 are arranged, and the two adsorption beds 103 are alternately in a water absorption state and a water release state. Figures 2 to 4 Corresponding pipelines 105 are arranged between the two adsorption beds 103 and between the adsorption bed 103 and the intermediate tank 102. Electromagnetic valves 110 can be arranged on different pipelines 105 to control the opening and closing of the corresponding pipelines 105. The specific arrangement of the pipelines 105 and the electromagnetic valves 110 is prior art, and will not be described here. The two adsorption beds 103 are arranged opposite to each other. The upper end of each adsorption bed 103 has an air inlet end, and the lower end has an air outlet end. The pipeline 105 connected with the air outlet end is provided with an air outlet 106.

[0031] For example, such as Figure 3 As shown, the adsorption bed 103 on the left is in a water-absorbing state. The external air is controlled to flow along path a by the corresponding solenoid valve 110. The moisture in the air is adsorbed by the adsorption bed 103 on the left, while the dry air is discharged from the exhaust port 106 on the exhaust end side of the adsorption bed 103 on the left. At this time, the adsorption bed 103 on the right side is in the water discharge state. The upper part of the inner cavity is connected to one end of the adsorption bed 103 on the right side through the corresponding solenoid valve 110. The other end of the adsorption bed 103 on the right side is connected to the upper part of the side cavity. At the same time, the lower part of the inner cavity is connected to the lower part of the side cavity. The motor drives the inner cylinder 201, the spiral blade 203 and the condenser 204 to rotate. Under the action of the thermoelectric cooler 202, the spiral blade 203 heats the air in the inner cavity and delivers it to the adsorption bed 103 on the right side. The water in the adsorption bed 103 on the right side is released in the form of steam and forms condensate droplets on the outer wall of the inner cylinder 201 and the condenser 204. At the same time, the condenser 204 rotates to throw the condensate droplets to the inner wall of the intermediate tank 102 and fall to the drain pipe 205 for collection. During this process, the air or water vapor in the inner cavity, the side cavity and the adsorption bed 103 on the right side flows along path b.

[0032] like Figure 4 As shown, the adsorption bed 103 on the right is in a water-absorbing state. The external air is controlled to flow along path c by the corresponding solenoid valve 110. The moisture in the air is adsorbed by the adsorption bed 103 on the right, while the dry air is discharged from the exhaust port 106 on the exhaust end side of the adsorption bed 103 on the right. At this time, the adsorption bed 103 on the left is in the water discharge state. The upper part of the inner cavity is connected to one end of the adsorption bed 103 on the left through the corresponding solenoid valve 110. The other end of the adsorption bed 103 on the left is connected to the upper part of the side cavity. At the same time, the lower part of the inner cavity is connected to the lower part of the side cavity. The motor drives the inner cylinder 201, the spiral blade 203 and the condenser 204 to rotate. Under the action of the thermoelectric cooler 202, the spiral blade 203 heats the air in the inner cavity and delivers it to the adsorption bed 103 on the left. The water in the adsorption bed 103 on the left is released in the form of steam and forms condensate droplets on the outer wall of the inner cylinder 201 and the condenser 204. At the same time, the condenser 204 rotates to throw the condensate droplets to the inner wall of the intermediate tank 102 and fall to the drain pipe 205 for collection. During this process, the air or water vapor in the inner cavity, the side cavity and the left side adsorption bed 103 flows along the path d.

[0033] In one of the embodiments, the box 101 is further provided with a water storage tank 107 communicated with the drain pipe 205, and the water storage tank 107 is provided with a displacement sensor 207 for detecting the rising speed of the liquid level in the water storage tank 107, and when the rising speed is greater than or equal to a preset value, the driving part increases the rotating speed of the inner cylinder 201; and when the rising speed is less than the preset value, the adsorption bed 103 in the water discharge state is switched to the water absorption state, and the adsorption bed 103 in the water absorption state is switched to the water discharge state.

[0034] When the rising speed of the liquid level in the water storage tank 107 is greater than or equal to the preset value, it indicates that the water content in the adsorption bed 103 in the water discharge state is relatively large, and the rotating speed of the inner cylinder 201 is increased by the driving part to improve the efficiency of the condensed water droplets being flung to the inner wall of the intermediate tank 102, further reduce the absorption of the condensed water droplets to the coldness of the condensing sheet 204, avoid the temperature of the condensing sheet 204 rising to affect the condensing effect, reduce the energy consumption, further avoid the thermal resistance caused by the water film formed on the condensing sheet 204, ensure the heat exchange efficiency and the condensing effect, ensure the overall performance of the system, and accelerate the gas flow in the inner cavity and the side cavity to improve the water production efficiency.

[0035] It is worth noting that when the rising speed of the liquid level in the water storage tank 107 is greater than or equal to the preset value at first and then less than the preset value after a certain period of time, it indicates that the water content in the adsorption bed 103 in the water discharge state is gradually discharged and reduced, and at this time, the adsorption bed 103 in the water discharge state needs to be switched to the water absorption state, and the adsorption bed 103 in the water absorption state needs to be switched to the water discharge state. When the rising speed of the liquid level in the water storage tank 107 is always less than the preset value, it indicates that the water content in the adsorption bed 103 in the water discharge state is relatively small, and therefore the rotating speed of the inner cylinder 201 needs to be increased by the driving part to ensure a certain water production efficiency.

[0036] The water storage tank 107 is arranged below the intermediate tank 102 and communicated with the intermediate tank 102 through the drain pipe 205. The displacement sensor 207 is arranged on the top wall of the water storage tank 107, and the bottom wall of the water storage tank 107 is provided with a discharge pipe provided with a valve. The working principle and arrangement of the displacement sensor 207 are both prior art, and will not be described here.

[0037] In one of the embodiments, referring to Figure 2 The box 101 is further provided with an extension piece 208 for moving the two adsorption beds 103 closer to or farther away from each other, and the two adsorption beds 103 can be moved close to each other to contact each other.

[0038] The telescopic member 208 enables the two adsorption beds 103 to move away from each other for water production. When the rising speed of the liquid level in the water storage tank 107 is less than a preset value, the temperature of the adsorption bed 103 in the water absorption state is lower, and the temperature of the adsorption bed 103 in the water release state is higher. The telescopic member 208 enables the two adsorption beds 103 to move close to each other to contact each other, and the two adsorption beds 103 exchange heat, so that the temperature of the adsorption bed 103 in the water absorption state is increased to facilitate the subsequent water release process, and the temperature of the adsorption bed 103 in the water release state is decreased to facilitate the subsequent water absorption process, thereby improving the energy utilization rate.

[0039] The telescopic member 208 can be a telescopic structure such as a hydraulic cylinder or an electric push rod, and is provided with a corresponding power source and a control module to control the start and stop and operating conditions. Referring to Figures 2 to 4 The output end of the telescopic member 208 is fixed to the left adsorption bed 103, and a telescopic pipe is arranged at the corresponding pipeline 105 to adapt to the relative movement of the left adsorption bed 103 and the right adsorption bed 103 and ensure the sealing. In addition, the bed bodies of the two adsorption beds 103 can be square boxes, and when the two adsorption beds 103 move close to each other to contact each other, they are in surface contact to increase the contact area and improve the heat exchange effect and efficiency.

[0040] It can be understood that the solar-powered air water production equipment of the present application also has a processor connected with the control module of the motor, the control module of the telescopic member 208, all electromagnetic valves 110, the fan and the displacement sensor 207 to control the operating conditions of the system. The specific setting mode of the above-mentioned processor is a prior art, which will not be described here.

[0041] In one embodiment, the condensing sheet 204 is in a spiral shape.

[0042] When the spiral condensing sheet 204 rotates, it has a downward conveying effect on the condensate droplets to speed up the collection of the condensate droplets.

[0043] In other embodiments not shown, the condensing sheet 204 can also be in a circular sheet shape or a fin shape, which does not have the downward conveying effect on the condensate droplets.

[0044] In one embodiment, the inner wall of the intermediate tank 102 is formed with vertically arranged water guide grooves 209, and the water guide grooves 209 are uniformly distributed along the circumference of the intermediate tank 102.

[0045] The condensing sheet 204 rotates to throw the condensate droplets along the tangential direction of the condensing sheet 204 to the inner wall of the intermediate tank 102, so that the condensate droplets are collected in the water guide grooves 209 and fall to the drain pipe 205 for collection, thereby further speeding up the collection of the condensate droplets.

[0046] The lower end of the water guide groove 209 penetrates to the bottom wall of the intermediate tank 102, so that the condensed water drops in the water guide groove 209 can fall to the bottom wall of the intermediate tank 102 and be discharged through the drain pipe 205.

[0047] In one of the embodiments, the bottom wall of the intermediate tank 102 gradually decreases from the center to the edge, and the drain pipe 205 is arranged at the edge of the bottom wall of the intermediate tank 102.

[0048] After the condensed water drops in the inner wall of the intermediate tank 102 fall to the bottom wall, they are conveniently collected at the drain pipe 205.

[0049] Preferably, the bottom wall has the lowest height at the position of the drain pipe 205, and gradually decreases to the position of the drain pipe 205, which further facilitates the collection of the condensed water drops at the drain pipe 205.

[0050] In one of the embodiments, the thermoelectric refrigerator 202 is in a cylindrical shape and coaxially arranged with the inner cylinder 201.

[0051] The acceleration of the temperature rise of the inner wall of the inner cylinder 201 and the spiral fin 203 and the temperature drop of the outer wall of the inner cylinder 201 and the condensing fin 204 improves the water production efficiency.

[0052] In one of the embodiments, the box 101 is provided with a dust removal box 108, which is used for dust removal of the air introduced from outside.

[0053] The fan introduces the air from outside into the dust removal box 108, the dust removal box 108 removes dust from the air, and the dust-removed air flows to the adsorption bed 103 along the corresponding pipeline 105. The structure and working principle of the dust removal box 108 are both prior art, and will not be described here.

[0054] The present application also provides the following embodiments, a solar-powered air water production system, comprising: A processor for controlling the adsorption bed 103 to switch between the water absorption state and the water discharge state; A solar panel 109 for powering the thermoelectric refrigerator 202.

[0055] The solar panel 109 is electrically connected with the thermoelectric refrigerator 202 and is provided with a control module, and the control module is connected with the processor. The above connection mode is prior art, and will not be described here. When the solar energy is abundant, the solar panel 109 can also power the motor and other related electrical appliances.

[0056] The working principle of the present application is as follows: The fan introduces the air from outside into the dust removal box 108, the dust removal box 108 removes dust from the air, and the dust-removed air flows to the adsorption bed 103 along the corresponding pipeline 105.

[0057] AsFigure 3 As shown, the adsorption bed 103 on the left is in a water-absorbing state. The external air is controlled to flow along path a by the corresponding solenoid valve 110. The moisture in the air is adsorbed by the adsorption bed 103 on the left, while the dry air is discharged from the exhaust port 106 on the exhaust end side of the adsorption bed 103 on the left. At this time, the adsorption bed 103 on the right side is in the water discharge state. The upper part of the inner cavity is connected to one end of the adsorption bed 103 on the right side through the corresponding solenoid valve 110. The other end of the adsorption bed 103 on the right side is connected to the upper part of the side cavity. At the same time, the lower part of the inner cavity is connected to the lower part of the side cavity. The motor drives the inner cylinder 201, the spiral blade 203 and the condenser 204 to rotate. Under the action of the thermoelectric cooler 202, the spiral blade 203 heats the air in the inner cavity and delivers it to the adsorption bed 103 on the right side. The water in the adsorption bed 103 on the right side is released in the form of steam and forms condensate droplets on the outer wall of the inner cylinder 201 and the condenser 204. At the same time, the condenser 204 rotates to throw the condensate droplets to the inner wall of the intermediate tank 102 and fall down along the water guide trough 209 to the drain pipe 205 for collection. During this process, the air or water vapor in the inner cavity, the side cavity and the adsorption bed 103 on the right side flows along path b.

[0058] like Figure 4 As shown, the adsorption bed 103 on the right is in a water-absorbing state. The external air is controlled to flow along path c by the corresponding solenoid valve 110. The moisture in the air is adsorbed by the adsorption bed 103 on the right, while the dry air is discharged from the exhaust port 106 on the exhaust end side of the adsorption bed 103 on the right. At this time, the adsorption bed 103 on the left is in the water discharge state. The upper part of the inner cavity is connected to one end of the adsorption bed 103 on the left through the corresponding solenoid valve 110. The other end of the adsorption bed 103 on the left is connected to the upper part of the side cavity. At the same time, the lower part of the inner cavity is connected to the lower part of the side cavity. The motor drives the inner cylinder 201, the spiral blade 203 and the condenser 204 to rotate. Under the action of the thermoelectric cooler 202, the spiral blade 203 heats the air in the inner cavity and delivers it to the adsorption bed 103 on the left. The water in the adsorption bed 103 on the left is released in the form of steam and forms condensate droplets on the outer wall of the inner cylinder 201 and the condenser 204. At the same time, the condenser 204 rotates to throw the condensate droplets to the inner wall of the intermediate tank 102 and fall down along the water guide trough 209 to the drain pipe 205 for collection. During this process, the air or water vapor in the inner cavity, the side cavity and the left side adsorption bed 103 flows along the path d.

[0059] The condenser plate 204 rotates to throw the condensed water droplets onto the inner wall of the intermediate tank 102, which to a certain extent reduces the absorption of cold energy by the condenser plate 204 by the condensed water droplets, avoids the temperature of the condenser plate 204 rising and affecting the condensation effect, and reduces energy consumption. At the same time, it avoids the thermal resistance caused by the formation of a water film on the condenser plate 204, ensuring heat exchange efficiency and condensation effect, and further ensuring the overall performance of the system.

[0060] The rising speed of the liquid level in the water storage tank 107 is detected by the displacement sensor 207, and when the rising speed of the liquid level in the water storage tank 107 is greater than or equal to a preset value, it indicates that the water content in the adsorption bed 103 in the water discharge state is relatively large. The rotation speed of the inner cylinder 201 is increased by the driving part to improve the efficiency of the condensate droplets being thrown to the inner wall of the intermediate tank 102, further reduce the absorption of the condensate droplets to the coldness of the condensing sheet 204, avoid the temperature rise of the condensing sheet 204 to affect the condensing effect, reduce the energy consumption, further avoid the thermal resistance caused by the water film formed on the condensing sheet 204, ensure the heat exchange efficiency and the condensing effect, ensure the overall performance of the system, speed up the gas flow in the inner cavity and the side cavity, and improve the water production efficiency. When the rising speed of the liquid level in the water storage tank 107 is less than the preset value, it indicates that the water content in the adsorption bed 103 in the water discharge state is relatively small, and the temperature of the adsorption bed 103 in the water absorption state is relatively low, and the temperature of the adsorption bed 103 in the water discharge state is relatively high. The two adsorption beds 103 can be close to each other by the telescopic part 208 to contact each other. The two adsorption beds 103 exchange heat, so that the temperature of the adsorption bed 103 in the water absorption state is increased to facilitate the subsequent water discharge process, and the temperature of the adsorption bed 103 in the water discharge state is reduced to facilitate the subsequent water absorption process, thereby improving the energy utilization rate. Then, the corresponding electromagnetic valve 110 is controlled to switch the adsorption bed 103 in the water discharge state to the water absorption state, and the adsorption bed 103 in the water absorption state to the water discharge state, thereby ensuring the continuous high water production efficiency.
