Description

Technical Field

[0001] The invention relates to the technical field of air water extraction, and in particular to a conical hood hopper air condensation water extraction device and method. Background Art

[0002] Water resources exist in nature in liquid, solid and gaseous states. Among them, water vapor in the atmosphere, as a potential form of water resources, has long been ignored by people. The water vapor content in the air is about six times the water content of surface rivers. If these gaseous water can be utilized, it can improve the water shortage problem in some areas to a certain extent. Therefore, the technology of air water extraction came into being.

[0003] At present, the mainstream air water extraction technologies are mainly the following three: condensation method, adsorption method, and membrane separation method. Condensation air water extraction technology is a technology that liquefies water vapor through condensation technology. It has the advantages of low cost, simple structure, and high working efficiency. It can be used in large-scale air water extraction environments, but it has high requirements for air humidity and condensation technology, and is not suitable for dry environments. Adsorption air water extraction technology is a method of producing liquid water by adsorbing water vapor in the air through adsorption materials. It can remove impurities and pollutants in the air and improve the quality and safety of water extraction, but it is only suitable for small-scale air water demand. Further research and development is needed for large-scale water demand. Membrane separation air water extraction technology is a technology that uses membrane separation principles to extract water from the air through polymer membranes, but its working efficiency is greatly affected by changes in ambient temperature and humidity, and its own cost is relatively high, so it is still in the development stage.

[0004] Combining the advantages and disadvantages of each technology, and considering the advantages of low cost and high efficiency of condensing air water extraction technology, the present invention adopts condensing air water extraction technology. There are various condensing air water extraction machines in the current technology as follows:

[0005] Patent CN202410206275.4 discloses a portable outdoor air water intake device, including a water intake mechanism and a drainage mechanism, wherein the drainage mechanism is used to introduce air in the water intake environment into the water intake mechanism, and the water intake mechanism includes a shell, and inside the shell, there are a receiving chamber, a guide circular chamber, a condensation chamber, and a water collection chamber from top to bottom, wherein the water collection chamber is used to collect condensed water, and the condensation chamber is used to condense the moisture in the air to form condensed water that enters the water collection chamber;

[0006] However, most of the drainage mechanisms of existing air water intake devices are arranged on the top of the entire device, and the incoming gas directly enters the condensation chamber and the water collection chamber. This method causes uneven gas flow rate and the gas condensation effect cannot be guaranteed. At the same time, the condensation device generally only has a condensation metal plate, resulting in low condensation efficiency. In addition, the existing device does not make reasonable use of the heat generated during the condensation process. Summary of the invention

The end of the discharge slot seat away from the air duct passes through the inner wall of the hollow box and is connected to the annular air flow channel.

[0016] As a further technical solution, a photovoltaic energy storage component is arranged on the top of the hollow box.

[0017] As a further technical solution, a filter element is fixed to the upper end of the inner side of the water tank.

[0018] In the second aspect, the present invention further proposes a water extraction method based on the conical hood air condensation water extraction device, as follows:

[0019] After the waterproof air pump is started to draw air from the air inlet into the hollow box, the air is heated by the heating device and filtered by the air filter plate, so that the air is continuously discharged downward into the metal cover bucket and condensed in contact with the metal cover bucket, and the excess air returns to the upper end of the metal cover bucket through the first ventilation hole and the second ventilation hole, and the condensed water is received by the water storage tank;

The plurality of electric heating rods 3 are used to heat the air entering the inner side of the hollow box body 1. In order to conveniently draw the air from the air inlet 2 into the hollow box body 1, a supporting plate 4 is horizontally fixed to the upper part of the space surrounded by the inner wall of the hollow box body 1. A waterproof air pump 8 is provided at the upper end of the supporting plate 4. The waterproof air pump 8 is used to draw the outside air into the hollow box body 1.

[0044] A certain space is reserved between the top of the inner wall and the top of the outer wall of the hollow box body 1, and an air filter plate 7 is fixed in the space; the air is filtered conveniently through the air filter plate 7, and the air suction port of the water-proof air pump 8 penetrates the hollow box body 1 and extends to the inner side of the air filter plate 7; the air outlet of the water-proof air pump 8 extends to the lower end of the bearing plate 4 and is connected to the metal cover 9;

[0045] A metal cover 9 is fixed to the bottom end of the carrier plate 4. In order to facilitate the further introduction of air into the inner side of the metal cover 9, the air outlet of the waterproof air pump 8 extends to the lower end of the carrier plate 4. In order to facilitate the lowering of the temperature of the metal cover 9 so that the air can condense due to the temperature difference when it contacts the metal cover 9, four semiconductor refrigeration sheets 12 are evenly arranged on the outer side of the metal cover 9. In order to facilitate the reception of condensed water, a water storage tank 10 is also arranged in the space surrounded by the inner wall of the hollow box body 1 and at the lower end of the metal cover 9.

[0049] The conical hood air condensation and water extraction device provided in the present embodiment sets the air inlet at the lower end of the outer wall. The incoming air is first buffered by the annular air flow channel so that the gas can enter the hollow box at a uniform speed, and then is filtered and heated to ensure the condensation effect of the gas. At the same time, the air can reduce impurities and dust in the air after being processed by the filter to ensure the clean air. At the same time, the air is heated by the heating device so that the air can carry more water vapor after being heated, thereby increasing the water content per unit volume. When the air is discharged into the inner side of the conical metal hood and contacts the conical metal hood for cooling, the conical metal hood has a larger contact area with the air than the traditional heat sink, which will help to improve the efficiency of condensation and water extraction. At the same time, the conical structure will help to drain and collect water droplets, and the semiconductor condensation sheet is connected to the outer side of the conical metal hood to cool the metal hood to ensure the temperature difference between the air and the surface of the metal hood for condensation and water extraction.
