[0001] This invention belongs to the field of dew collection technology, specifically relating to a dew collection device and method based on a chemical reagent method. Background Technology

[0002] Most dew collection devices on the market are simple experimental devices with many defects in collection efficiency and effect: (1) Simple experimental dew collection devices on the market generally use semiconductor cooling chips for cooling. Semiconductor cooling chips are difficult to solve the problem of low cooling efficiency and need another connector for heat dissipation, which leads to changes in ambient temperature; (2) Traditional dew collection devices simply rely on high humidity and large temperature difference to obtain dew; (3) In terms of traditional chemical reagent material addition, most of them require manual control of the amount, but it is difficult to accurately control the amount of reagents by manual addition, and the requirements for manual strength are also very high.

[0003] Therefore, it is urgent to improve the existing dew collection devices to solve the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a dew collection device and method based on chemical reagents to solve the technical problem of low dew collection efficiency in existing dew collection devices.

[0005] To address the aforementioned problems, the present invention employs the following technical solution:

[0006] In a first aspect, a dew collection device based on a chemical reagent method includes a fixed rod and a reactor. The fixed rod is vertically installed on the ground. The reactor is fixedly connected to the fixed rod via a first connecting rod. The reactor is a hollow inverted cone. A reactor cover is provided at the top of the reactor. Several feed inlets are provided on the surface of the reactor cover. Several feeding modules are provided above the reactor cover. The feeding modules are used to feed chemical reagents into the reactor through the feed inlets. An outlet is provided at the bottom of the reactor. A second gate is provided at the outlet. The outlet is connected to a waste bin via a pipeline. A dew collection pool is provided below the outlet.

[0007] A further improvement of the present invention is that: the feeding module includes a solid silo and an electric conveyor; the solid silo has an opening at its bottom, and a first gate is provided at the opening at the bottom of the solid silo; the opening at the bottom of the solid silo is aligned with the inlet of the electric conveyor; the outlet of the electric conveyor is connected to the inlet on the reactor cover plate via a pipeline; the solid silo is connected to a fixed rod via a second connecting rod; one end of the second connecting rod near the solid silo is sleeved on the outer side of the upper half of the solid silo; the other end of the second connecting rod away from the solid silo is fixedly connected to the fixed rod; a third connecting rod is provided below the electric conveyor; the third connecting rod is perpendicular to the fixed rod; one end of the third connecting rod is fixedly connected to the fixed rod; and a weighing sensor is provided below the electric conveyor.

[0008] A further improvement of the present invention is that the chemical reagent is one or more of ammonium nitrate crystals and / or sodium carbonate decahydrate crystals.

[0009] A further improvement of the present invention is that the mass ratio of the ammonium nitrate crystals to the sodium carbonate decahydrate crystals is 2:3.

[0010] A further improvement of the present invention is that it also includes a power supply module, which includes a wind turbine, a solar panel and a battery. The wind turbine is mounted on the top of the fixed rod, and the solar panel is located below the wind turbine. A support rod is provided between the solar panel and the fixed rod. The battery is mounted on the ground and is electrically connected to the wind turbine and the solar panel respectively. The battery is also electrically connected to the feeding module, the second gate and the electric mixer respectively.

[0011] A further improvement of the present invention is that it also includes an automatic control module, which includes a PLC processing chip and a resistance temperature sensor. The resistance temperature sensor is disposed between the reactor and the fixed rod. The PLC processing chip is electrically connected to the feeding module, the second gate, the resistance temperature sensor and the battery.

[0012] A further improvement of the present invention is that: the outer wall surface of the reactor is provided with a hydrophilic coating and a hydrophobic coating, the hydrophilic coating is arranged in several tree-shaped patterns uniformly on the outer wall surface of the reactor, and the hydrophobic coating is provided on the outer wall surface of the reactor where no hydrophilic coating is provided.

[0013] A further improvement of the present invention is that: the top of the tree-shaped pattern is located at the bottom edge of the outer wall of the reactor, the shape of the top of the tree is conical, and the bottom of the tree-shaped pattern is located at the top of the outer wall of the reactor.

[0014] A further improvement of the present invention is that it also includes a mesh sheet disposed above the dew collection pool.

[0015] Secondly, a dew collection device based on a chemical reagent method includes the following steps:

[0016] The ambient temperature around the reactor is obtained by a resistance temperature sensor and uploaded to the PLC processing chip. When the ambient temperature is equal to the local outdoor temperature, the electric stirrer is turned off and the second gate is opened to discharge the waste material after the previous reaction.

[0017] The first gate is opened, and the chemical reagent in the solid silo is sent into the electric conveyor. The weighing sensor obtains the weight of the chemical reagent and uploads it to the PLC processing chip. When the weight of the chemical reagent reaches the preset value, the first gate and the second gate are closed, and the electric conveyor starts to work, pouring the chemical reagent into the reactor.

[0018] Start the electric stirrer to make the chemical reagent reaction endothermic, and dew will be generated on the outer wall of the reactor. The dew will drip into the dew collection tank through the outer wall of the reactor, thus completing the dew collection.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects:

[0020] 1. This invention improves the efficiency of dew collection by setting the reactor as an inverted cone and installing a reactor cover plate on the top of the reactor, thereby increasing the condensation rate of dew on the outer wall of the reactor through endothermic reaction inside the reactor. The dew on the outer wall of the reactor flows into the dew collection tank along the outer side of the reactor.

[0021] 2. This invention improves the efficiency of water vapor condensation and transport on the water collection surface by setting a tree-shaped hydrophilic coating on the upper part of the outer wall of the reactor, and by combining the tree-shaped pattern with hydrophilic and hydrophobic coatings, and makes it less prone to the adhesion of impurities.

[0022] 3. This invention utilizes the endothermic reaction of two chemical reagents to achieve refrigeration. It has a wide temperature range and will not reduce the collection efficiency due to the influence of ambient temperature.

[0033] Example 1

[0034] like Figure 1As shown, a dew collection device based on a chemical reagent method includes several feeding modules, a power supply module, a fixing rod 16, a first connecting rod 171, a reactor 6, a reactor cover plate 61, a second gate 7, a waste bin 10, a dew collection pool 8, and a mesh 9. The fixing rod 16 is vertically fixed to the ground, and several feeding modules are fixed around the fixing rod 16. The fixing rod 16 is fixedly connected to the reactor 6 through the first connecting rod 171. The reactor 6 is an inverted cone with a circular opening at the top and an opening at the bottom. The opening at the top of the reactor 6 is closed by the reactor cover plate 61, which has several openings. The reactor 6 has a dry inlet, with the number of inlets matching the number of feeding modules. Each feeding module's outlet is connected to the inlet on the reactor cover plate 61 via a hollow tube. The reactor cover plate 61 also has a through hole in its center.

One end of the electric stirrer 5 is fixed to the bottom surface of the electric stirrer bracket, and the other end is located inside the reactor 6. The electric stirrer 5 passes through the through hole at the midpoint of the reactor cover plate 61. During installation, the electric stirrer 5 can be passed through the through hole, and then the end of the electric stirrer 5 furthest from the reactor 6 can be fixedly connected to the electric stirrer bracket.

[0035] The feeding module includes a solid silo 1, a first gate 2, and an electric conveyor 3. The solid silo 1 is used to store chemical reagents. The upper half of the solid silo 1 is cylindrical, and the lower half is an inverted cone. The bottom of the solid silo 1 has an opening. The first gate 2 is located on both sides of the bottom opening of the solid silo 1. The first gate 2 is used to control the feeding of solid silo 1. The bottom opening of the solid silo 1 is aligned with the feed inlet of the electric conveyor 3. When the first gate 2 is opened, the chemical reagents in the solid silo 1 fall into the feed inlet of the electric conveyor 3. The discharge outlet of the electric conveyor 3 is connected to the feed inlet on the reactor cover plate 61 through a pipeline. Solid silo 1 is connected to fixed rod 16 via second connecting rod 172.

The support rod also creates an angle between the solar panel 13 and the fixed pole 16, and the angle is determined according to the positional relationship between the solar panel 13 and the sun during actual use. The storage battery 15 is installed on the ground and is electrically connected to the wind turbine 14 and the solar panel 13. The wind turbine 14, the solar panel 13 and the storage battery 15 supply power to the first gate 2, the second gate 7, the electric stirrer 5, the electric conveyor 3, the weighing sensor 4, the PLC processing chip 11 and the thermistor temperature sensor 12. The electricity is collected by the solar panel 13 and the wind turbine 14 and stored in the storage battery 15 for long-term use. The wind and solar complementary energy supply is adopted to achieve self-sufficiency in electricity and maximize the utilization of wind and solar energy.

[0037] like Figure 3As shown, it also includes an automatic control module, which can automatically collect dew without human intervention. The automatic control module includes a PLC processing chip 11 and a resistance temperature sensor 12. The PLC processing chip 11 is mounted on the fixed rod 16, and can be installed on the surface or inside the fixed rod 16, depending on the specific environment.

[0038] In a preferred embodiment of the present invention, the chemical reagents are sodium carbonate decahydrate crystals (Na2CO3·10H2O) and ammonium nitrate crystals (NH4NO3). Sodium carbonate decahydrate crystals are inexpensive, costing 12.0 yuan / 500g, and their environmental pollution is less than that of reagents used in common chemical reagent methods, such as barium hydroxide.

[0039] In a preferred embodiment of the present invention, the mass ratio of NH4NO3 to Na2CO3·10H2O is 2:3, at which point the refrigeration effect is optimal and the low temperature is maintained for a long time. At this mass ratio, the temperature rise is less than 3°C after 3 hours, and 2g of this refrigerant can absorb 160J of heat, resulting in a 25×10⁻⁶ kJ / kg temperature. -3 m 3 The air is cooled by 5℃ in a space (assuming an adiabatic system, the specific heat of air is 29.21 J / mol·K at 101.325 kPa and 15℃). Two chemical reagents are placed into different feeding modules. There are as many feeding modules as there are chemical reagents, and the feeding modules have the same structure.

[0040] In a preferred embodiment of the present invention, both the first gate 2 and the second gate 7 are bidirectional spiral gates.

[0041] In a preferred embodiment of the present invention, the outer wall surface of the reactor 6 is provided with a hydrophilic coating 181 and a hydrophobic coating 182, wherein the hydrophilic coating 181 forms a plurality of tree-shaped patterns, such as... Figure 3As shown, the top of each tree pattern is conical, and the top of each tree pattern is close to the edge of the reactor cover plate 61. The bottom of each tree pattern is close to the bottom center of the reactor 6. The outer surface of the reactor 6 is covered by a hydrophobic coating 182 except for the hydrophilic coating 181. The tree pattern has a higher efficiency in collecting water vapor from the air than a homogeneous hydrophilic and hydrophobic surface. The surface energy gradient at the boundary of the tree pattern pushes the tiny droplets on the hydrophobic coating 182 into the hydrophilic coating 181, thereby forming larger droplets on the hydrophilic coating 181 more quickly. Since the corners of the tree pattern are all conical, a Laplace pressure difference can also be provided to promote the directional movement of droplets and further improve the water collection efficiency. When the water droplet grows to the critical size, it will roll off the surface due to gravity. The droplet gathers at the branches of the tree pattern and is transported downward at the trunk of the tree pattern, and is eventually collected. After the dew condenses on the outer wall of the reactor 6, it can flow into the dew collection pool 8 under the action of gravity along the outer surface of the reactor 6.

[0042] In a preferred embodiment of the present invention, the mesh 9 is an 8-mesh mesh, which prevents foreign objects or insects from entering the dew collection pool 8.

[0043] In a preferred embodiment of the present invention, the electric conveyor 3 is a screw structure, which is driven by a motor to rotate the screw for transporting solid drugs. Transporting solid drugs by the electric conveyor 3 can prevent the solid drugs from splashing during the transport process.

[0044] Example 2

[0045] A dew collection method based on a chemical reagent method, using a dew collection device based on a chemical reagent method as described in Example 1, includes the following steps:

[0046] The ambient temperature around the reactor 6 is obtained by the resistance temperature sensor 12 and uploaded to the PLC processing chip 11. When the ambient temperature is equal to the local outdoor temperature, the electric stirrer 5 is turned off and the second gate 7 is opened to discharge the waste material after the last reaction.

[0047] Open the first gate 2 and send the chemical reagent in the solid silo 1 into the electric conveyor 3. At this time, the weighing sensor 4 obtains the weight of the chemical reagent and uploads it to the PLC processing chip 11. When the weight of the chemical reagent reaches the preset value, close the first gate 2 and the second gate 7, and the electric conveyor 3 starts to work, pouring the chemical reagent into the reactor 6.

[0048] Start the electric stirrer 5 to make the chemical reagent reaction endothermic, and dew is generated on the outer wall of reactor 6. The dew drips into the dew collection tank 8 through the outer wall of reactor 6 to complete the dew collection.

[0049] The above process is repeated under the control of PLC processing chip 11.

[0050] The PLC processing chip 11 is connected to the control system, so the opening and closing of each part can be controlled individually by the control system, or the working time of the whole device can be set to realize the timed opening and closing of the device.
