TECHNICAL FIELD
[0001] The present application relates to the technical field of wettable surfaces, in particular to a manufacturing method of a fog collector with a spiral structure and the fog collector. BACKGROUND
[0002] The fog collection device is a system for collecting water resources from fog, which is generally composed of a humidifier, a fog collector, a water collection container and a support, wherein the fog collector is the core component for intercepting and capturing small droplets in the fog. The traditional fog collector mainly relies on one-dimensional and two-dimensional design, such as linear structure and planar mesh structure, but these structures have obvious limitations in fog water collection efficiency. The water droplets on the one-dimensional structure are easy to adhere to the surface of the fiber and difficult to fall off, and the surface area of a single fiber is limited, so the amount of fog water captured per unit time is small. The planar mesh will hinder the passage of wind-borne fog flow, reducing the collision probability of fog droplets; water droplets are difficult to direct and gather, and the dripping efficiency is low; and it is easy to deform or break in strong wind environment, affecting long-term use.

[0029] To make the technical problems, technical solutions and advantages to be solved by the present application clearer, specific embodiments will be described in detail below with reference to the drawings.
[0030] The present application provides a manufacturing method of a fog collector with a helical structure, as shown in Figure 1 , comprising the following steps:
[0031] S10. Obtain a sheet-shaped body 1, which is of a hydrophilic material, has hydrophilicity, has a plurality of through holes 3 on the center line of the sheet-shaped body 1 along the length direction of the sheet-shaped body 1, the through holes 3 penetrate the sheet-shaped body 1 along the thickness direction of the sheet-shaped body 1, and a micro groove array structure is processed on the upper surface and the lower surface of the sheet-shaped body 1, respectively, the micro groove array structure is composed of a plurality of micro grooves with a width of microns;
[0032] S20. Cutting triangular spikes 2 along the width direction of the sheet-shaped body 1, it can be understood that the triangular spikes 2 are distributed on both sides of the width of the sheet-shaped body 1, and the triangular spikes 2 are oriented in the same direction along the length direction of the sheet-shaped body 1.
[0033] S30. Coating the upper surface and the lower surface of the sheet-shaped body 1 with a super-hydrophobic agent and air-drying;
[0034] S40. Spiral winding the cut sheet-shaped body 1 on a column with a radius R, and fixing for a predetermined time, thereby completing the manufacturing of the fog collector.
[0035] In the use of the present application, the tip of the triangular thorn 2 is ensured to be downward, and the three-dimensional structure of the spiral structure can make the airflow pass through efficiently, improve the effect of collision and capture of mist droplets. Specifically, first, the sheet-shaped body 1 with a spiral structure is arranged with symmetrical triangular thorns 2 on both sides, and the fog collector can make the windward surface and the leeward surface of the fog collector contact the fog, and intercept part of the fog to make it move along the spiral path of the fog collector, generating a vortex. Compared with the traditional one-dimensional and two-dimensional structure, the spiral structure increases the contact area with the fog, providing multiple points for fog condensation. Second, triangular thorns 2 are arranged on both sides of the sheet-shaped body 1, which increases the micro area on the surface area of the sheet-shaped body 1, effectively increases the overall structure condensation area, and helps efficient condensation of the fog and directional delivery of the liquid droplets formed by condensation. When the fog flows through the fog collector, the triangular thorns 2 on both sides fully realize the disturbance and deceleration of the fog flow, ensuring that the fog flow stays longer inside and around the fog collector, and the fog molecules have more opportunities to contact and condense on the surface of the fog collector.
[0036] At the same time, a plurality of through holes 3 are formed on the center line of the sheet-shaped body 1. When the air rises, the air can pass through the slits or through holes 3 of the fog collector. Since the air passing through the through holes 3 has less resistance and less kinetic energy loss, it can maintain a high speed. The high-speed airflow continuously pushes the uncondensed fog outside the fog collector, ensuring that the surface of the fog collector is more uniform and effective in participating in condensation.
[0037] In combination with the aforementioned spiral structure, the surface of the sheet-shaped body 1 is formed with a micro groove array structure, and the surface of the micro groove array structure is coated with a super-hydrophobic agent. Under the action of the micro groove array structure and the super-hydrophobic agent, it helps the fog to quickly condense into mist droplets and promotes the aggregation of the mist droplets. Under the guidance of the spiral structure, the mist droplets overcome the surface tension and roll down along the spiral path of the fog collector, forming a directional water delivery path, reducing the risk of evaporation of the fog during rolling.
[0038] Specifically, step S10 includes the following contents:
[0039] S11. Clean the surface of the sheet-shaped body 1, and fix the sheet-shaped body 1 on the workbench. The sheet-shaped body 1 is pre-planned and marked on the upper and lower surfaces of the sheet-shaped body 1. Adjust the parameters of the laser equipment, and move the laser equipment above the workbench.
[0040] In this step, the sheet-shaped body 1 adopts an aluminum plate with a thickness of 0.1 mm, a length of 130 mm, a width of 30 mm, a length of the to-be-processed region of 120 mm, a width of the to-be-processed region of 20 mm, and a geometric center of the to-be-processed region coinciding with a geometric center of the sheet-shaped body 1, so that the sheet-shaped body 1 has a margin at the edge, and the sheet-shaped body 1 can be fixed on the workbench through the margin part. The sheet-shaped body 1 can be fixed by the prior art.
[0041] In this application, a laser marking machine is used to process a plurality of micro-hole structures on the sheet-shaped body 1. The laser scanning speed is adjusted to 1000 mm / s, the laser scanning line spacing is adjusted to 0.02 mm, the laser frequency is adjusted to 20 KHz, and the laser power ratio is adjusted to 100%.
[0042] The laser marking machine is turned on, and a linear micro groove column is first processed on the sheet-shaped body 1 in the width direction of the to-be-processed region. After one micro groove column is completed, the laser marking machine is translated by 0.02 mm in the length direction, and a second micro groove column is processed again in the width direction. A plurality of micro groove columns arranged in the width direction form the aforementioned micro groove array structure. Understandably, the running route of the laser marking machine when ablating each micro groove column is the length direction of the micro groove column.
[0043] After the micro groove array structure on the upper surface of the sheet-shaped body 1 is completed, the sheet-shaped body 1 is turned over so that the lower surface of the sheet-shaped body 1 faces upward, and the micro groove array structure is manufactured on the lower surface by the same method.
[0044] Since the aluminum material itself has hydrophilicity, the micro groove array structure is manufactured on the sheet-shaped body 1 of the aluminum material, so that the surface of the sheet-shaped body 1 is rougher, the actual contact area with the fog is increased, and therefore the sheet-shaped body 1 has super hydrophilicity at this time.
[0045] S20. Cutting triangular spines 2 along the width direction of the sheet-shaped body 1, and the cut triangular spines 2 are arranged along the length direction of the sheet-shaped body 1 and have the same direction.
[0046] In this step, first, the scanning speed of the laser marking machine is adjusted, the scanning speed is adjusted to 450 mm / s, and the laser marking machine is used for cutting in the to-be-processed region to form triangular spines 2, wherein the included angle between the triangular spine 2 and the positive direction of the long side direction is , , the tip angle of the triangular spine 2 is , , the spine spacing between adjacent triangular spines 2 is , ; the distance between two triangular spines 2 in the width direction is D (i.e., the ridge width is D), 2 mm < D < 16 mm.
[0047] After the cutting, the sheet body 1 presents the shape as shown in Figure 2 .
[0048] In the embodiment, the tip of the triangular spike 2 has a high radius of curvature, which can effectively capture water molecules from the fog and make the fog condense more easily. The fog droplets condense and grow at the tip of the triangular spike 2, move from the tip to the root of the spike under the Laplace pressure difference, contact the fog droplets between the triangular spike 2 and the adjacent triangular spike 2, and complete the convergence. When the fog droplets converge to a certain extent, the fog droplets overcome the gravity and fall along the root of the triangular spike 2 to the tip, accelerate the falling speed of the fog droplets, and improve the capture efficiency.
[0049] S30. After the cutting, the sheet body 1 is coated with a super-hydrophobic agent and air-dried.
[0050] In the embodiment, the thickness of the sheet body 1 is only 0.1 mm, so the super-hydrophobic agent is only coated on the upper and lower surfaces of the sheet body 1 to form a super-hydrophobic layer on the surface of the sheet body 1.
[0051] In the application, the super-hydrophobic agent is a tetradecanoic acid alcohol reagent with a concentration of 0.02 mol / L, which is obtained by mixing 0.27-0.28 g of tetradecanoic acid with 60 ml of 99% industrial ethanol solution and stirring until no precipitate is formed. The super-hydrophobic agent is coated on the upper and lower surfaces of the sheet body 1 and air-dried to obtain an aluminum sheet body with a super-hydrophobic surface.
[0052] S40. The cut aluminum sheet body with super-hydrophobicity is wound on a column with a radius of , as shown in Figure 3 , without showing the triangular spike 2 and the through hole 3. During the winding process, the spiral angle of the sheet body 1 is , , and is fixed for a predetermined time to shape the aluminum sheet body and obtain a fog collector.
[0053] As shown in Figure 4 , the application also provides a fog collector made by the foregoing method, wherein the spiral angle , the spiral radius , the tip angle of the spike , the included angle between the triangular spike 2 and the long side direction , the ridge width , and the spike spacing .
