Description

Technical Field

[0001] This invention relates to the field of air-water extraction technology, specifically a solar-powered adsorption-type air-water extraction unit. Background Technology

[0002] Island regions and fishing villages generally face a shortage of freshwater resources, a situation caused by natural conditions, infrastructure, and human factors. Regarding natural conditions, topography limits the construction of large-scale water storage facilities, resulting in limited water storage capacity; furthermore, transportation constraints lead to high costs for freshwater transport and storage. In terms of infrastructure, many islands and fishing villages have lagged behind in water supply system development, and seawater desalination is costly and its widespread adoption is limited. Meanwhile, water pollution, over-exploitation of groundwater, and poor management exacerbate the freshwater shortage. Overall, the freshwater predicament of islands and fishing villages is difficult to fundamentally alleviate. Given the inherently high atmospheric moisture content of island regions, a new technology is needed to improve freshwater access.

[0003] Currently available air-to-water technology suffers from drawbacks such as high water production costs and limited water output. Energy consumption costs limit the practical application value of air-to-water generators. Adsorption materials directly affect water extraction efficiency and cost control. Adsorption-based water extraction technology is still immature, equipment is unstable, and large-scale production faces significant challenges. Summary of the Invention

[0004] The purpose of this invention is to provide a solar-powered adsorption-type air-water extraction unit to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a solar-powered adsorption-type air-to-water unit, comprising a left shell plate and a right shell plate. An adsorption bed plate one and an adsorption bed plate two are disposed inside the right shell plate. An adsorption bed assembly one is disposed on the top surface of the adsorption bed plate one, and an adsorption bed assembly two is disposed on the top surface of the adsorption bed plate two. An adsorption bed assembly one air inlet valve is disposed on the back of the adsorption bed assembly one, and an adsorption bed assembly one air outlet valve is disposed on the front of the adsorption bed assembly one. An adsorption bed assembly two air inlet valve is disposed on the back of the adsorption bed assembly two, and an adsorption bed assembly two air outlet valve is disposed on the front of the adsorption bed assembly two. An adsorption bed fan is disposed at one end of the adsorption bed assembly one air inlet valve. A condenser is disposed at the bottom of the left shell plate, and a hot water outlet pipe is disposed at the bottom of the condenser. A condenser fan is disposed on one side of the condenser. A hot water inlet pipe is disposed at the top of the left shell plate, and an electric three-way valve is disposed at the top of the hot water inlet pipe. An internal exhaust pipe is disposed inside the left shell plate.

[0006] Preferably, the heat exchange tubes of the condenser are made of finned copper tubes to enhance heat exchange.

[0007] Preferably, the adsorption bed fan is located at one end of the second air inlet valve of the adsorption bed. The first air inlet valve and the second air inlet valve of the adsorption bed allow air to enter through the adsorption bed fan, thereby performing adsorption operations through air.

[0008] Preferably, the first air inlet valve of the adsorption bed is located at the rear end of the left shell plate, and the first air outlet valve of the adsorption bed is located at the front end of the left shell plate. The first air inlet valve and the second air inlet valve of the adsorption bed allow gas to flow through the adsorption bed assembly inside the left shell plate and the adsorption bed body plate.

[0009] Preferably, the second air inlet valve of the adsorption bed is located at the rear end of the right shell plate, and the second air outlet valve of the adsorption bed is located at the front end of the right shell plate.

[0010] Preferably, the first adsorption bed is located in the inlet pipe of the condenser, and the second adsorption bed is located in the inlet pipe of the condenser. The condenser condenses the water vapor inside the first and second adsorption beds, facilitating the collection of the condensed water. Compared with the prior art, the beneficial effects of the present invention are: This solar-powered adsorption-type air-to-water unit fully utilizes solar energy and humid air during both adsorption and desorption processes, eliminating the need for electric heating and achieving a more energy-efficient operation. During desorption, the solar collector provides energy, effectively reducing energy consumption and controlling water production costs.

[0011] This solar-powered adsorption-type air-to-water unit effectively adsorbs water vapor under low humidity conditions. The island environment has high humidity, so the water extraction performance of this device can be better utilized. The system is equipped with an intelligent system, namely a humidity sensor, a temperature sensor, and an automatic control system. By controlling the opening and closing of each valve according to changes in humidity and temperature, the adsorption and desorption rates are adjusted to ensure water extraction under the most energy-efficient conditions.

[0012] This solar-powered adsorption-type air-to-water unit synthesizes a novel silica gel / MgCl2 composite material through an impregnation method. The equilibrium adsorption capacity is approximately 0.35 g / g, and the adsorption capacity in the 8th cycle is 92%–93% of that in the 1st cycle, demonstrating good cycle stability and high recycling value. Silica gel, as a common adsorbent, has abundant surface hydroxyl groups on its pore surface and is mainly used for adsorption drying and pressure swing adsorption to produce CO2. Silica gel is not only abundant and readily available, but its preparation method is also simple, resulting in good adsorption performance and high economic efficiency.

[0013] This solar-powered adsorption-type air-to-water unit features a system with two adsorption beds, allowing one bed to desorb water while the other desorbs, enabling continuous operation. This design not only improves water extraction efficiency but also avoids energy waste caused by waiting for desorption in traditional methods, thus enhancing the utilization efficiency of solar energy.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-4 The present invention provides the following technical solutions: A solar-powered adsorption-type air-to-water unit includes a left shell plate 1 and a right shell plate 2. An adsorption bed plate 5 and an adsorption bed plate 6 are disposed inside the right shell plate 2. An adsorption bed assembly 3 is disposed on the top surface of the adsorption bed plate 5, and an adsorption bed assembly 4 is disposed on the top surface of the adsorption bed plate 6. An adsorption bed inlet valve 11 is disposed on the back of the adsorption bed assembly 3, and an adsorption bed outlet valve 16 is disposed on the front of the adsorption bed assembly 3. The adsorption bed inlet valve 11 is located at the rear end of the left shell plate 1, and the adsorption bed outlet valve 16 is located at the front end of the left shell plate 1. The adsorption bed inlet valve 11 and the adsorption bed outlet valve 16 allow gas to flow through the adsorption bed assembly 3 inside the left shell plate 1 and the adsorption bed plate 5.

[0018] The back of the second adsorption bed assembly 4 is provided with an adsorption bed second air inlet valve 12, and the front of the second adsorption bed assembly 4 is provided with an adsorption bed second air outlet valve 17. The adsorption bed second air inlet valve 12 is located at the rear end of the right shell plate 2, and the adsorption bed second air outlet valve 17 is located at the front end of the right shell plate 2. An adsorption bed fan 9 is provided at one end of the first adsorption bed air inlet valve 11 and at one end of the second adsorption bed air inlet valve 12. Air is introduced through the adsorption bed fan 9 to perform adsorption operations.

[0019] A condenser 8 is installed at the bottom of the interior of the left shell plate 1. Adsorption bed group 1 3 is installed in the air inlet pipe of the condenser 8, and adsorption bed group 2 4 is installed in the air inlet pipe of the condenser 8. The condenser 8 performs condensation of water vapor inside adsorption bed group 1 3 and adsorption bed group 2 4, which facilitates the collection of condensed water. The heat exchange tubes of the condenser 8 are made of finned copper tubes to enhance heat exchange.

[0020] A hot water outlet pipe 15 is provided at the bottom of the condenser 8, a condenser fan 10 is provided on one side of the condenser 8, a hot water inlet pipe 14 is provided at the top of the left shell plate 1, an electric three-way valve 13 is provided at the top of the hot water inlet pipe 14, and an internal exhaust pipe 7 is provided inside the left shell plate 1.

[0021] During use, when the adsorption process is carried out, the valves of three-way valve one, three-way valve two, three-way valve three and three-way valve four are opened alternately, and the adsorption bed fan 9 is started to drive the air circulation in the equipment, so that the air alternately enters the adsorption bed group one 3 and the adsorption bed group two 4 to complete the adsorption process of the adsorption bed.

[0022] During the adsorption process, the ventilation valve in the device is opened, and air enters adsorption bed group 3 or adsorption bed group 4 through the pipe under the action of the fan. The adsorbent exposed to the air captures moisture by utilizing its hydrophilicity, and uses the difference between the vapor pressure of the adsorbent surface and the vapor pressure of the ambient air as the driving force for moisture absorption. At the same time as completing the adsorption process, the heat of adsorption is dissipated, and dry air is discharged into the environment.

[0023] During the desorption process, the valves of the three-way valves 3, 4, 2 and 1 at the fresh air inlet are closed alternately, while the vacuum valves 3-way valve 10 and 9 are opened alternately, so that the adsorption bed is alternately in a vacuum state.

[0024] The system controls the closure of the fresh air inlet valve. The air-to-water intake device utilizes solar energy to obtain energy from the solar collector, raising the temperature of the hot water in the pipes. Simultaneously, the hot water flows into the pipes surrounding adsorption bed group 3 or adsorption bed group 4, heating the adsorbent. The adsorbent undergoes desorption, and the desorbed water vapor enters condenser 8. In condenser 8, the water vapor exchanges heat with an external cold source, releasing heat into the air. The water vapor liquefies into water droplets, which eventually leave condenser 8 due to gravity and enter the water storage tank. Water vapor enters the heat exchange tubes of condenser 8 and condenses into water, releasing heat. A condenser fan 10 is installed on one side of condenser 8, and a filter screen structure is installed at the air inlet. After the condenser fan 10 is started, it drives the sea air to flow through the heat exchange tubes and carry away the heat, keeping the temperature of condenser 8 below 30 degrees Celsius.

[0025] A water collection tank is installed below the condenser 8. The condensate in the heat exchange tubes of the condenser 8 drips into the water collection tank due to gravity.

[0026] Once the desorption water production mode is completed, the desorbed water, after effective filtration, can be supplied to the family for daily use.

[0027] This achieves the effect of one adsorption bed carrying out the adsorption process and another adsorption bed carrying out the desorption process, flexibly alternating and controlling the water absorption volume, and working continuously during the day, thereby improving the operating efficiency of the device.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
