Description

Technical Field

[0001] This invention relates to the field of adsorption desorption components, and in particular to a rotary adsorption desorption component and its application. Background Technology

[0002] Currently, researchers have proposed various air-to-water extraction devices, most of which use adsorption / desorption methods to obtain fresh water from the air. These devices first use hygroscopic materials to adsorb moisture from the air. After adsorption is complete, the hygroscopic materials are heated to a high temperature by direct sunlight or by other energy sources such as electricity to desorb the moisture. Finally, the desorbed high-temperature humid air is condensed to obtain liquid water. However, these air-to-water extraction devices have the following problems.

[0003] Because the air temperature is high and the relative humidity is low during the day, it is not conducive to the adsorption of moisture from the air by the hygroscopic material. Therefore, most water is taken by adsorption at night and desorption during the day. That is, the water taking cycle is generally one day and night. It is impossible to achieve adsorption and desorption at the same time, which seriously restricts the continuity and efficiency of water taking by the device. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that, in order to solve the problem that the existing water collection devices are not conducive to the adsorption of moisture in the air by the hygroscopic material during the day due to the high air temperature and low relative humidity, most of them adopt the form of adsorption at night and desorption during the day, that is, the water collection cycle is generally one day and night, which cannot achieve simultaneous adsorption and desorption, and seriously restricts the continuity and efficiency of water collection of the device. Now, a rotary adsorption and desorption component and its application are provided.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a rotary adsorption and desorption assembly, including a rotary base, a plurality of adsorption and desorption plates are rotatably mounted on the outer peripheral surface of the rotary base, the rotation center of the adsorption and desorption plates is arranged radially along the rotary base, and a speed control mechanism for controlling its rotation speed is provided on the rotary base.

[0006] The speed control mechanism includes several swing limiting components corresponding to the adsorption and desorption plates. Each swing limiting component includes a front limiting component and a rear limiting component. The adsorption and desorption plates are located between the front and rear limiting components. The front and rear limiting components are arranged along the axial direction of the rotating base. Both the front and rear limiting components are used to contact the corresponding front or rear limiting component of the adsorption and desorption plate when the rotating base rotates, and can control the swing amplitude of the adsorption and desorption plates according to the rotation speed of the rotating base. Several adsorption and desorption plates are arranged in the same direction along the outer circumference of the rotating base. Compared to existing technologies, this solution controls the rotation speed of the rotating base through the speed control mechanism. Under different wind conditions, the rotation speed control of the adsorption and desorption components is stable and reliable, ensuring stable and reliable hydrological data collection and improving the water collection efficiency of the equipment. Simultaneously, the front and rear limiting components, arranged along the axial direction of the rotating base, restrict the swing of the adsorption and desorption plates to the axial range of the rotating base, ensuring that the rotating base always rotates in the same direction under different wind directions.

[0007] To implement the front and rear limiting components, in some preferred embodiments, both the front and rear limiting components include a fixed plate and a movable plate slidably mounted on the fixed plate. The fixed plate is fixedly mounted on a rotating base, and the movable plate is tangentially arranged along the rotation direction of the rotating base. The movable plate is located on the side of the fixed plate closer to the adsorption / desorption plate, and the movable plate contacts the adsorption / desorption plate. A telescopic mechanism is provided between the movable plate and the fixed plate to retract as the centrifugal force increases or extend as the centrifugal force decreases during the rotation of the rotating base. By sliding the movable plate on the fixed plate, and with the sliding direction of the movable plate tangentially arranged along the rotating base, the movable plate can slide on the fixed plate during rotation, and in conjunction with the telescopic mechanism, control the swing range of the adsorption / desorption plate, thereby controlling the rotational speed of the rotating body.

[0008] To realize the telescopic mechanism, in some preferred embodiments, the telescopic mechanism includes a counterweight, a guide wheel, and a pull rope. The counterweight is slidably mounted on a fixed plate along the radial direction of the rotating base. The guide wheel is rotatably mounted on a movable plate. One end of the pull rope is disposed on the fixed plate, and the other end of the pull rope is wrapped around the guide wheel and fixedly connected to the counterweight. The counterweight is located on the side of the fixed plate away from the rotating base.

[0009] To better restore the movable plate to its initial state, in some preferred embodiments, the restoration mechanism includes a spring, one end of which is fixed to a fixed plate, and the other end of which is fixed to the movable plate with a pull rope.

[0010] In order to enable the movable plate to slide on the fixed plate, in some preferred embodiments, the fixed plate is provided with a sliding groove that matches the movable plate, one end of the movable plate is matched with the sliding groove, the movable plate is slidably disposed in the sliding groove, and the telescopic mechanism is located in the sliding groove.

[0011] In order to enable the counterweight to slide on the fixed block, in some preferred embodiments, the fixed plate is provided with a guide groove along the radial direction of the rotating base, the guide groove is matched with the counterweight, and the counterweight is slidably disposed in the guide groove.

[0012] In some preferred embodiments, the rotating base is cylindrical, and a mounting hole is provided at the center of rotation of the rotating base.

[0013] A rotary adsorption-desorption device includes a device body on which a rotary adsorption-desorption component as described above is rotatably mounted. The device body has an adsorption channel and a desorption channel spaced apart axially. An adsorption zone is provided within the adsorption channel, and a desorption zone is provided within the desorption channel. The adsorption zone and desorption zone are correspondingly arranged. One part of the rotary adsorption-desorption component is located in the adsorption zone, and the other part is located in the desorption zone. The adsorption channel is for introducing humid air, and the desorption channel is for introducing high-temperature air.

[0014] An air dehumidifier is equipped with a rotary adsorption and desorption component as described above.

[0015] An air-to-water collector is equipped with a rotary adsorption and desorption assembly as described above.

[0016] The beneficial effects of this invention are as follows: When the rotary adsorption-desorption component and its application are used, the rotation speed of the rotating base is controlled by the speed control mechanism. Under different wind conditions, the rotation speed of the adsorption-desorption component is stable and reliable, ensuring stable and reliable water intake and improving the water intake efficiency of the equipment. At the same time, the front limit component and the rear limit component are set along the axial direction of the rotating base, restricting the adsorption-desorption plate to swing within the axial range of the rotating base. This ensures that the rotating base always rotates in the same direction under different wind conditions. This avoids the problem that existing water intake devices often use the form of adsorption at night and desorption during the day when the air temperature is high and the relative humidity is low, which is not conducive to the adsorption of moisture in the air by the hygroscopic material. As a result, most of them adopt the form of adsorption at night and desorption during the day, that is, the water intake cycle is generally one day and night. It is impossible to achieve simultaneous adsorption and desorption, which seriously restricts the continuity and efficiency of water intake of the device. Attached Figure Description

[0030] Example 1

[0031] like Figure 1-6 As shown, a rotary adsorption-desorption assembly includes a rotary base 1 and several adsorption-desorption plates 2. The several adsorption-desorption plates 2 are rotatably mounted on the rotary base 1 via a rotary shaft. The several adsorption-desorption plates 2 are evenly distributed along the circumference of the rotary base 1 on the cylindrical surface of the rotary base 1, thereby increasing the adsorption-desorption area and improving the adsorption-desorption efficiency. It also makes the rotary adsorption-desorption assembly rotate more smoothly. The rotation center of the adsorption-desorption plates 2 is set radially along the rotary base 1, or adjacent adsorption-desorption plates 2 are staggered. The staggering can increase the adsorption-desorption area and improve the adsorption-desorption efficiency. A speed control mechanism is provided on the rotary base 1 to control its rotation speed. The distance between the rotation shafts of two adjacent adsorption-desorption plates 2 is greater than the rotation radius of the adsorption-desorption plates 2, so that the adsorption-desorption plates 2 will not interfere with each other when swinging under the action of wind force changes.

[0032] The speed control mechanism includes several swing limiting components 3, which are correspondingly arranged with the adsorption and desorption plate 2. The swing limiting components 3 include a front limiting component 4 and a rear limiting component 5. The adsorption and desorption plate 2 is located between the front limiting component 4 and the rear limiting component 5. The front limiting component 4 and the rear limiting component 5 are arranged along the axial direction of the rotating base 1. The front limiting component 4 and the rear limiting component 5 are both used to contact the front limiting component 4 or the rear limiting component 5 on the corresponding side of the adsorption and desorption plate 2 when the rotating base 1 rotates, and can control the swing amplitude of the adsorption and desorption plate 2 according to the rotation speed of the rotating base 1. The movable plate 7 on the front limiting component 4 and the movable plate 7 on the rear limiting component 5 face the same direction. At the same time, several adsorption and desorption plates 2 are arranged and swing in the same direction on the rotating base 1.

[0033] Both the front limiting assembly 4 and the rear limiting assembly 5 include a fixed plate 6 and a movable plate 7. The fixed plate 6 is provided with a groove 12 that matches the movable plate 7. One end of the movable plate 7 matches the groove 12, and the movable plate 7 is slidably disposed in the groove 12. The telescopic mechanism is located in the groove 12, so that the movable plate 7 can be slidably mounted on the fixed plate 6. The fixed plate 6 is fixedly mounted on the rotating base 1. The movable plate 7 is tangentially arranged along the rotation direction of the rotating base 1. The movable plate 7 is located on the side of the fixed plate 6 close to the adsorption and desorption plate 2. The movable plate 7 is in contact with the adsorption and desorption plate 2. A telescopic mechanism is provided between the movable plate 7 and the fixed plate 6 for contracting as the centrifugal force of the rotating base 1 increases or extending as the centrifugal force decreases when the rotating base 1 rotates.

[0034] The telescopic mechanism includes a counterweight 8, two guide wheels 9, a pull rope 10, and a spring 11. A guide groove 13 is provided on the fixed plate 6 along the radial direction of the rotating base 1. The guide groove 13 matches the counterweight 8. The counterweight 8 is slidably disposed in the guide groove 13, so that the counterweight 8 can be slidably mounted on the fixed plate 6 along the radial direction of the rotating base 1. The guide wheels 9 are rotatably mounted on the fixed plate 6. One end of the pull rope 10 is disposed on the movable plate 7. The other end of the pull rope 10 passes through the guide wheels 9 on the fixed plate 6 in sequence and is fixedly connected to the counterweight 8. The counterweight 8 is located on the side of the fixed plate 6 away from the rotating base 1. One end of the spring 11 abuts against the fixed plate 6, and the other end of the spring 11 abuts against the movable plate 7.

[0035] The rotating base 1 is cylindrical, and a mounting hole 14 is provided on the rotating base 1 at its rotation center.

[0036] When the above-mentioned rotary adsorption and desorption component and its application are used, assuming that under a certain wind force, the rotating base 1 of the rotary adsorption and desorption component rotates stably at a certain angular velocity, when the wind force increases, the centrifugal force on the counterweight 8 of the telescopic mechanism of the adsorption and desorption plate 2 increases, and the movable plate 7 retracts on the fixed plate 6, the counterweight 8 moves outward, and the circumferential force increases, causing the spring 11 to compress, which increases the swing amplitude of the adsorption and desorption plate 2, and the force of the wind on the adsorption and desorption plate 2 decreases, thereby reducing the rotation speed of the rotating base 1 and maintaining it at a stable speed, so that the rotation speed of the rotating base 1 is controlled within a range, and it will not rotate too fast under strong winds;

[0037] When the wind force decreases, the centrifugal force on the movable plate 7 of the telescopic mechanism of the adsorption and desorption plate 2 decreases, which in turn reduces the circumferential force. The counterweight 8 moves inward, and under the action of the spring 11, the movable plate 7 extends out of the fixed plate 6, which reduces the swing amplitude of the adsorption and desorption plate 2. The force of the wind on the adsorption and desorption plate 2 increases, which increases the rotation speed of the rotating base 1 and keeps it at a stable speed. This ensures that the rotation speed of the rotating base 1 is controlled within a certain range, so that it does not rotate too slowly when the wind force is small.

[0038] Regardless of the wind force or whether the wind direction is the same or opposite, the adsorption and desorption plate 2 on the rotating base 1 always rotates counterclockwise under the action of the wind.

[0039] Example 2

[0040] Example 2 is an implementation of Example 1, specifically as follows: Figure 7 As shown, a rotary adsorption-desorption device includes a device body 15. A rotary adsorption-desorption assembly, as described above, is rotatably mounted on the device body 15 along its axial direction. The device body 15 has a flow channel, and a baffle is arranged along its axial direction within the flow channel, dividing the flow channel into an adsorption flow channel 16 and a desorption flow channel 17. An adsorption zone 18 is provided within the adsorption flow channel 16, and a desorption zone 19 is provided within the desorption flow channel 17. The adsorption zone 18 and the desorption zone 19 are correspondingly arranged. One part of the rotary adsorption-desorption assembly is located in the adsorption zone 18, and the other part is located in the desorption zone 19. The adsorption flow channel 16 can be connected to a flow channel containing... The fluid of the adsorbent medium is adsorbed by the adsorption and desorption component and rotated to the desorption channel 17. Upon contact with the fluid in the desorption channel 17, the adsorbable medium is desorbed again from the adsorption and desorption component and absorbed by the fluid in the desorption channel 17. The desorbed adsorption and desorption plate 2 continues to rotate to the adsorption zone 18 for adsorption again, and so on. In this embodiment, the adsorption channel 16 is for introducing humid air, and the adsorption and desorption plate 2 located in the adsorption zone 18 adsorbs water vapor in the humid air. The desorption channel 17 is for introducing high-temperature air, and the high-temperature air located in the desorption zone 19 desorbs the water vapor adsorbed by the adsorption and desorption plate 2 and becomes high-temperature humid air.

[0041] When in use, the adsorption and desorption plates 2 are aligned in the same direction under the action of wind, and the circumferential component of the wind's thrust on the blades is aligned in the same direction, driving the rotating base 1 to rotate. If the wind direction in the adsorption channel 16 and the desorption channel 17 is opposite, when the adsorption and desorption plates 2 move from the adsorption channel 16 to the desorption channel 17, the wind direction reverses, and the adsorption and desorption plates 2 swing to the other side under the action of wind. At this time, the direction of the force on the blades changes, but the circumferential component of the wind's thrust on the blades is still aligned in the same direction, driving the rotating base 1 to rotate. The same applies when the adsorption and desorption plates 2 move from the desorption channel 17 to the adsorption channel 16. Furthermore, by arranging the adsorption and desorption plates 2 in opposite directions to the wind in the adsorption channel 16 and the desorption channel 17, the adsorption and desorption plates 2 can periodically flip and impact the limiting block, thus achieving the function of dust removal.

[0042] Example 3

[0043] Example 3 is an implementation of Example 1, specifically: an air dehumidifier, equipped with the rotary adsorption and desorption component as described above, where humid air flows through the adsorption channel 16 inside the dehumidifier, water vapor is adsorbed, humidity is reduced, and the air dehumidification effect is achieved.

[0044] Example 4

[0045] Example 4 is an implementation of Example 1, specifically as follows: Figure 8 As shown, an air water collector includes a condensing device, a water collection device, and the aforementioned rotary adsorption and desorption assembly. The condensing device can be a plate heat exchanger, a shell-and-tube heat exchanger, a heat exchange coil, etc. The cold source for the condensing device can be cold air, cold water, liquid nitrogen, etc. The water collection device can be a cyclone demister, an inertial blade demister, a wire mesh demister, etc. One end of the aforementioned rotary adsorption and desorption assembly is connected to the water collection device at the input end of the condensing device, and the water collection device at the output end of the condensing device is connected. Moist air flows through the adsorption and desorption plates 2 in the adsorption channel 16, and water vapor is adsorbed by the adsorption and desorption plates 2, reducing the humidity of the moist air. High-temperature air flows through the adsorption and desorption plates 2 in the desorption channel 17, absorbing the water vapor desorbed by the adsorption and desorption plates 2 and becoming saturated moist air. The saturated moist air flows through the condensing device, and the water vapor condenses into water droplets. The saturated moist air with water droplets coming out of the condensing device enters the water collection device, where the water droplets are collected.

[0046] The above description, based on the preferred embodiments of the present invention, provides inspiration. Those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification but must be determined according to the claims.
