Description

Technical Field

[0001] The present invention belongs to the technical field of dew collection in arid areas, and particularly relates to a device and method for collecting and utilizing dew in arid areas. Background Art

[0002] In arid areas, the rainfall is scarce, evaporation is intense, and water resources are short. As a non-precipitation liquid water source on the land surface, dew is an important water resource for plant growth, small animals and microorganisms to survive. And this water source can be directly drunk by humans after micro-treatment. If it can be utilized, it will be of great significance to alleviate the contradiction between water supply and demand in arid areas.

[0003] In recent years, many scholars have carried out a lot of work on the development and utilization of dew resources. For example, Nikolayer V S, et al (1996) made a conical or flat dew collector with a wide opening and a small size, which can maximize the intensity of nocturnal radiative cooling, reduce the thermal inertia of the dew condensation surface, lower the surface temperature to a lower level, keep it below the dew point for more time, and at the same time enable full exchange of water vapor on the surface, so that more dew can be obtained. The test results of Lekouch, et al (2012) in the Mrocco area showed that dew can be directly collected and treated for daily use by households; although there are already some collection and utilization devices at present, the collection devices are complex and costly, and are not convenient for popularization and application. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a device for collecting and utilizing dew in arid areas in view of the deficiencies in the above-mentioned prior art. Its design is novel and reasonable. By designing the dew collection panel into a right-angled triangle structure and installing it upside down, it provides a basis for the inclined installation of the diversion groove while being convenient for connection. The condensate drainage members are designed to be offset up and down and interpenetrate each other, which largely avoids the mutual influence of the dew collection surfaces, and makes it possible to place more dew collection surfaces in more space as much as possible to increase the dew collection area. The protrusions on the dew collection panel accelerate the condensation of water droplets, and the non-protrusion areas speed up the rolling and sliding of water droplets. Combining the characteristics of large temperature difference between day and night in arid areas, dew is collected through the dew condensation principle, which fully reflects the efficient utilization of water resources in arid areas, water conservation, environmental friendliness, and is easy to manufacture, low in price, and convenient for popularization and use.

[0014] At the same time, the present invention also discloses a method with simple steps, reasonable design and capable of collecting dew in arid areas, which is characterized in that the method includes the following steps:

[0015] Step 1: Determine the number of dew collection and utilization devices in arid areas: Determine the number of dew collection and utilization devices in arid areas according to the area of the dew collection area, and evenly place the corresponding number of dew collection and utilization devices in the dew collection area;

[0016] Step 2: Determine the height of the condensation and drainage unit in the dew collection and utilization device in arid areas: Determine the height of the condensation and drainage unit in the dew collection and utilization device in arid areas according to the topographic and geomorphic conditions of the dew collection area and the weather preset of the dew collection area.

As the environmental temperature drops, the temperature of the aluminum dew collection panel quickly drops below the environmental temperature, receiving the water vapor transmitted in the air. After the raised areas coated with a super-hydrophilic coating on the aluminum dew collection panel receive the water vapor transmitted in the air, the water vapor quickly condenses into water droplets on the surface of the raised areas. As the water droplets accumulate, the water droplets roll down through the non-raised areas coated with a super-hydrophobic coating on the aluminum dew collection panel into the diversion channels coated with a super-hydrophobic coating, and then flow into the water inlet holes along the slopes of the diversion channels and drop into the confluence pipe;

[0023] In the above method, it is characterized in that: Two aluminum dew collection panels arranged back to back in the condensation and drainage member are bonded by metal glue.

[0024] The present invention has the following advantages compared with the prior art:

The non-protrusion areas and the diversion grooves on the side of the dew collection panel where the protrusions are provided are both coated with a super-hydrophobic coating, which speeds up the rolling and sliding of water droplets, avoids the adhesion of dew to the non-protrusion areas and the diversion grooves, reduces the loss of the collected dew amount, and reduces the evaporation of dew.

[0029] 5. The present invention can adapt to different terrains, does not consume energy, is easy to install, and has a low cost.

[0030] 6. The method adopted in the present invention has simple steps. Determine the number of dew collection and utilization devices in the arid area according to the area of the dew collection area, and combine the topographic and geomorphic conditions of the dew collection area and the weather preset of the dew collection area to determine the height of the condensate diversion unit in the dew collection and utilization device in the arid area. Reduce energy consumption through the automatic dew collection method in the arid area, which is green and environmentally friendly, and the dew utilization is effective and convenient for popularization and use.

[0044] The protrusions 10 are coated with a super-hydrophilic coating, and the non-protrusion areas on the side of the dew collection panel 2 where the protrusions 10 are arranged and the diversion grooves 12 are both coated with a super-hydrophobic coating.

[0045] It should be noted that by setting up the condensation and confluence mechanism and combining with the characteristics of large temperature difference between day and night in arid areas, dew is collected through the dew condensation principle, which fully reflects the efficient utilization of water resources in arid areas and water conservation. By setting up the support mechanism to adjust the height of the dew collection panel 2, the dew collection panel 2 can be placed at the most suitable environmental height, and the adjustment is simple. In addition, by setting up the utilization mechanism to utilize the water resources collected by the condensation and confluence device, it is green and environmentally friendly, easy to manufacture, and low in price. A plurality of condensation and confluence mechanisms are arranged along the length direction of the confluence pipe 1. In each condensation and drainage unit, each set of the condensation and drainage components includes a plurality of condensation and drainage parts evenly arranged on the circumferential side of the confluence pipe 1. The condensation and drainage parts in the two sets of the condensation and drainage components are arranged in a vertically staggered and mutually inserted manner on the outer side wall of the confluence pipe 1, which largely avoids the mutual influence of the dew collection surfaces and makes it possible to utilize more space to place more dew collection surfaces to increase the dew collection area. The dew collection panel 2 is designed into a right-angled triangle structure and installed upside down, which is convenient for connection and provides a basis for the inclined installation of the diversion groove 12. Moreover, the two condensation and drainage parts in the condensation and drainage part are arranged back to back, forming a structure in which both sides of one condensation and drainage part collect dew, and the two diversion grooves 12 in one condensation and drainage part extend into the same water inlet hole 11, reducing the number of openings and simplifying the structure. A plurality of protrusions 10 are arranged on the side of the dew collection panel 2 away from the other condensation and drainage part in the corresponding condensation and drainage part, and a super-hydrophilic coating is applied on the protrusions 10, which increases the collection area and accelerates the condensation of dew. The non-protrusion area on the side of the dew collection panel 2 where the protrusions 10 are arranged and the diversion groove 12 are both coated with a super-hydrophobic coating, which speeds up the rolling and sliding of water droplets, avoids the adhesion of dew to the non-protrusion area and the diversion groove 12, reduces the loss of the collected dew amount, and reduces the evaporation of dew.

[0046] During actual use, the super-hydrophilic coating uses XZ-GT01 nano-hydrophilic coating silicon, which has the functions of reinforcement, anti-shear, matting and thixotropy; the super-hydrophobic coating selects fluorocarbon compounds, which have the important characteristics of waterproof, anti-fog, anti-snow, anti-pollution, anti-adhesion, anti-oxidation, anti-corrosion, self-cleaning and preventing current conduction. The materials of the selected super-hydrophilic coating and super-hydrophobic coating are both new environmentally friendly multi-functional coatings.

[0047] In this embodiment, the support mechanism includes a tight belt fixer 13 sleeved on the lower section of the confluence pipe 1 and a support frame 3 installed outside the tight belt fixer 13, and the support frame 3 is a telescopic support frame.

[0048] In this embodiment, the telescopic support frame is a three-legged telescopic support frame.

[0049] It should be noted that by adjusting the height of the confluence pipe 1 through the three-legged telescopic support frame, different terrains can be adapted, no energy is consumed, and the installation is convenient and the cost is low.

[0050] In this embodiment, the utilization mechanism includes a water storage tank 6 and a reducing pipe 4 installed at the bottom end of the confluence pipe 1. One end of the reducing pipe 4 far from the confluence pipe 1 is communicated with the water storage tank 6 through a hose 5. A water pipe 8 is arranged at the bottom of the water storage tank 6, and a water valve 7 is installed on the water pipe 8.

[0051] In this embodiment, the reducing pipe 4 is a reducing pipe with a larger upper diameter and a smaller lower diameter. The large-diameter end of the reducing pipe 4 is communicated with the confluence pipe 1, and the small-diameter end of the reducing pipe 4 is communicated with the hose 5.

[0052] During actual use, the dew converged in the confluence pipe 1 is gathered through the reducing pipe 4 and led into the water storage tank 6 through the hose 5. The dew collected in multiple water storage tanks 6 can all flow into the reservoir through the water pipe 8 for utilization; it can be directly discharged and utilized through the water pipe 8 respectively, or it can be inserted into the plant roots through a connecting conduit, so as to achieve the purpose of restoring the ecological vegetation of crops in arid and other regions.

[0053] In this embodiment, a pipe cap 9 is installed at the top end of the confluence pipe 1.

[0054] It should be noted that the purpose of installing the pipe cap 9 at the top end of the confluence pipe 1 is to prevent sand and dust from entering the dew collection and utilization device and affecting the dew quality.

[0055] In this embodiment, the protrusion 10 is an arc-shaped protrusion. The protrusion 10 and the diversion groove 12 in the condensation and drainage split body are located on the same side and face away from the other condensation and drainage split body in the corresponding condensation and drainage member. The acute angle between the diversion groove 12 and the central axis of the confluence pipe 1 is 30° to 60°. The dew collection panel 2 is coplanar with the central axis of the confluence pipe 1. The diversion groove 12, the dew collection panel 2 and the connecting plate 14 are processed and made into one body, and the diversion groove 12 and the dew collection panel 2 are arranged at 90° to each other.

The distance between two adjacent protrusions 10 in the same row and the distance between two adjacent protrusions 10 in the same column are less than the maximum width of one protrusion 10.

[0057] Such as Figure 4 shown, a method for collecting dew in arid areas includes the following steps:

[0058] Step 1. Determine the number of dew collection and utilization devices in arid areas: Determine the number of dew collection and utilization devices in arid areas according to the area of the dew collection area, and evenly place the corresponding number of dew collection and utilization devices in the dew collection area;

[0059] Step 2. Determine the height of the condensation and drainage unit in the dew collection and utilization device in arid areas: Determine the height of the condensation and drainage unit in the dew collection and utilization device in arid areas according to the topographical and geomorphic conditions of the dew collection area and the preset weather in the dew collection area. By adjusting the support mechanism, fix the protruding height of the confluence pipe 1, and then locate the height of the condensation and drainage unit in the dew collection and utilization device in arid areas;

[0060] The dew collection panels 2 in the condensation and drainage unit are all aluminum dew collection panels, which have a small specific heat capacity, fast heating and cooling speeds under the same heat conditions, improve the intensity of nocturnal radiative cooling, reduce the thermal inertia of the dew condensation surface, make the surface temperature easier to drop to a lower state, and will make the dew condensation surface below the dew point for more time. Compared with plastic, wooden stick or PVC materials, it is more conducive to dew condensation.

[0061] The protrusion 10 is an arc-shaped protrusion. The protrusion 10 and the diversion groove 12 in the condensation and drainage unit are located on the same side and face away from the other condensation and drainage unit in the corresponding condensation and drainage part. The acute angle between the diversion groove 12 and the central axis of the confluence pipe 1 is 30° - 60°. The dew collection panel 2 and the central axis of the confluence pipe 1 are coplanar. The diversion groove 12, the dew collection panel 2 and the connecting plate 14 are processed and made into one body, and the diversion groove 12 and the dew collection panel 2 are arranged at 90° to each other;

[0062] Step 3. Automatic dew collection in arid areas: The aluminum dew collection panel forms a layer of aluminum oxide in the air to isolate the air and protect the aluminum dew collection panel from corrosion. As the environmental temperature in the dew collection area decreases, the temperature of the aluminum dew collection panel quickly drops below the environmental temperature, receiving the water vapor transmitted in the air. After the protrusion 10 coated with a super-hydrophilic coating on the aluminum dew collection panel receives the water vapor transmitted in the air, the water vapor quickly condenses into water droplets on the surface of the protrusion 10. As the water droplets gather more and more, the water droplets roll down to the diversion groove 12 coated with a super-hydrophobic coating through the non-protruding area coated with a super-hydrophobic coating on the aluminum dew collection panel, and then flow into the water inlet hole 11 along the slope of the diversion groove 12 and fall into the confluence pipe 1;

[0063] Step 4. Dew utilization: The dew automatically collected on each aluminum dew collection panel flows into the confluence pipe 1, and then enters the utilization mechanism through the confluence pipe 1. The utilization mechanism includes a water storage tank 6 and a reducing pipe 4 installed at the bottom end of the confluence pipe 1. One end of the reducing pipe 4 away from the confluence pipe 1 is connected to the water storage tank 6 through a hose 5. A water pipe 8 is provided at the bottom of the water storage tank 6, and a water valve 7 is installed on the water pipe 8;

[0064] The dew collected in multiple water storage tanks 6 is all converged into the reservoir through the water pipe 8 for future use;

[0065] Or the dew collected in multiple water storage tanks 6 is directly discharged and utilized through the water pipe 8 respectively.

[0066] In this embodiment, two aluminum dew collection panels arranged back to back in the condensation drainage member are bonded by metal glue.

[0067] When the present invention is used, by designing the dew collection panel into a right-angled triangle structure and installing it upside down, it provides a basis for the inclined installation of the diversion groove while facilitating connection. The condensation drainage member is designed to be offset up and down and interpenetrate each other, which largely avoids the mutual influence of the dew collection surfaces and makes the best use of more space to place more dew collection surfaces to increase the dew collection area. The protrusions on the dew collection panel accelerate the condensation of water droplets, and the non-protrusion areas accelerate the rolling and sliding of water droplets. Combining the characteristics of large temperature difference between day and night in arid areas, dew is collected through the principle of dew condensation, which fully reflects the efficient utilization of water resources in arid areas, water conservation, environmental friendliness, and is easy to manufacture and inexpensive.

[0068] The above are only the preferred embodiments of the present invention, and do not impose any limitations on the present invention. Any simple modifications, changes, and equivalent structural changes made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.

Determine the number of dew collection and utilization devices in the arid area: Determine the number of dew collection and utilization devices in the arid area according to the area of the dew collection area, and evenly place the corresponding number of dew collection and utilization devices in the arid area on the dew collection area; Step 2. Determine the height of the condensation and drainage unit in the dew collection and utilization device in the arid area: Determine the height of the condensation and drainage unit in the dew collection and utilization device in the arid area according to the topographic and geomorphic conditions of the dew collection area and the preset weather in the dew collection area.

Automatic dew collection in the arid area: The aluminum dew collection panel forms a layer of aluminum oxide by oxidation in the air, isolating the air and protecting the aluminum dew collection panel from corrosion. As the environment temperature in the dew collection area decreases, the temperature of the aluminum dew collection panel quickly drops below the environment temperature, receiving the water vapor transmitted in the air. After the protrusion (10) coated with a super-hydrophilic coating on the aluminum dew collection panel receives the water vapor transmitted in the air, the water vapor quickly condenses into water droplets on the surface of the protrusion (10). As the water droplets gather more and more, the water droplets roll to the diversion groove (12) coated with a super-hydrophobic coating through the non-protruding area coated with a super-hydrophobic coating on the aluminum dew collection panel, and then flow into the water inlet hole (11) along the slope of the diversion groove (12), and then fall into the confluence pipe (1); Step 4.
