Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation equipment, and more specifically to a water vapor collection structure and irrigation system. Background Technology

[0002] In greenhouses, liquid water lost through plant respiration and transpiration, as well as soil evapotranspiration, remains in the greenhouse as water vapor, increasing humidity. Excessive humidity inhibits plant transpiration, and water vapor condenses on the greenhouse covering material, reducing light transmittance and increasing the risk of pathogens multiplying in the soil. It is also detrimental to the health of workers in the greenhouse.

[0003] Currently, greenhouses commonly use ventilation to reduce the temperature and humidity inside. This measure results in a significant loss of water resources, and if the temperature drop caused by ventilation is not properly controlled when the outside temperature is relatively cold, it can easily affect the growth of plants inside the greenhouse. Summary of the Invention

[0004] The purpose of this invention is to overcome the technical problem in the existing technology that, because existing greenhouses use ventilation to regulate humidity, most of the water resources in the greenhouse are lost to the outside in the form of steam, which prevents the full utilization of water resources in the greenhouse.

[0005] To achieve the above objectives, the present invention provides a water vapor collection structure.

[0006] The water vapor collection structure includes:

[0007] A condensate drain pipe, used to connect an irrigation pipe and a drip irrigation pipe, the condensate drain pipe including an inlet for communication with the irrigation pipe and an outlet for communication with the drip irrigation pipe; and

[0008] A condensate recovery assembly, comprising a manifold funnel disposed below the condensate drain pipe and a recovery pipe connected to the manifold funnel.

[0009] The lower end of the condenser drain pipe is provided with an inclined surface that slopes toward the water outlet, so as to guide the water vapor condensed and liquefied on the surface of the condenser drain pipe into the manifold funnel.

[0010] The water vapor collection structure provided by this invention provides an attachment structure for airborne water vapor by incorporating a condenser-shaped pipeline connecting irrigation and drip irrigation lines. This condenser-shaped pipeline, connected to the irrigation and drip irrigation lines, maintains a low temperature under the influence of flowing irrigation water, facilitating the condensation and liquefaction of airborne water vapor into a water flow. A condensate recovery assembly located below the condenser-shaped pipeline uses a collection funnel to collect the condensed water vapor and recover it through a recovery pipeline. This allows for the collection of airborne water vapor for secondary use, improving irrigation water utilization and reducing humidity in the greenhouse, which is beneficial for plant growth. This solves the technical problem of existing greenhouses where humidity is controlled by ventilation, resulting in water resources being lost to the outside as vapor, thus hindering the full utilization of greenhouse water resources.

[0011] Preferably, the water vapor collection structure includes a zigzag-shaped connecting pipe, which is disposed between the water outlet and the drip irrigation pipeline and bends towards the side closer to the confluence funnel.

[0012] Preferably, the bending angle formed by the axial extension line of the bend in the irregularly shaped connecting pipe and the horizontal plane is α.

[0013] Preferably, the surface of the condensate drain pipe is provided with an anti-corrosion coating layer.

[0014] Preferably, the surface of the condensate drain pipe is provided with structural grooves / protrusions.

[0015] Preferably, the water vapor collection structure includes a water storage tank, which is connected to the recovery pipeline.

[0016] A second aspect of the present invention provides an irrigation system.

[0017] The irrigation system includes irrigation pipelines, drip irrigation pipelines, and water vapor collection structures according to any one of the above, with multiple water vapor collection structures equally spaced between the irrigation pipelines and the drip irrigation pipelines.

[0018] Preferably, the irrigation pipeline is disposed above the drip irrigation pipeline, wherein the condensate drain pipe is disposed vertically between the irrigation pipeline and the drip irrigation pipeline; or, the condensate drain pipe is disposed at an angle β between the irrigation pipeline and the drip irrigation pipeline.

[0019] Preferably, the recovery pipeline is connected to the irrigation pipeline or the drip irrigation pipeline.

[0020] Preferably, the recovery pipeline is connected to the irrigation pipeline or drip irrigation pipeline through a water storage tank, and a one-way valve and / or a delivery pump are provided between the water storage tank and the irrigation pipeline or drip irrigation pipeline.

[0033] like Figures 1 to 4As shown, this invention provides a water vapor collection structure that can be used in a greenhouse plant irrigation system. The water vapor collection structure includes a condensate drain pipe 1 and a condensate recovery assembly 6. The condensate drain pipe 1 is composed of multiple through pipes, specifically referencing a drain pipe structure commonly used for heating. The condensate drain pipe 1 connects an irrigation pipe 2 and a drip irrigation pipe 3. The condensate drain pipe 1 includes an inlet 4 for communication with the irrigation pipe 2 and an outlet 5 for communication with the drip irrigation pipe 3. Irrigation water from the irrigation pipe 2 enters the condensate drain pipe 1 through the inlet 4 and then enters the drip irrigation pipe 3 through the outlet 5 for irrigating crops. When the irrigation water flows through the condensate drain pipe 1, due to the low temperature of the irrigation water itself, heat exchange occurs between the irrigation water and the condensate drain pipe under the action of the water flow. This ensures that the surface temperature of the condensate drain pipe 1 remains low, which is beneficial for condensing and liquefying water vapor in the air to form water droplets or even water streams. The condensate drain pipe 1 is preferably made of a metal with a high thermal conductivity. The condensate recovery assembly 6 includes a manifold funnel 7 located below the condensate drain pipe 1 and a recovery pipe 8 connected to the manifold funnel 7. The lower end of the condensate drain pipe 1 has an inclined surface 101 that slopes towards the outlet 5 to guide the condensed water vapor on the surface of the condensate drain pipe 1 into the manifold funnel 7. In a further optional embodiment of the invention, the upper end of the condensate drain pipe 1 also has an inclined surface. This inclined surface extends outward from the condensate drain pipe 1 and slopes downward, making the condensate drain pipe 1 hexagonal in shape. This structure facilitates the collection of condensed water vapor adhering to the condensate drain pipe 1, thereby improving the water vapor collection efficiency.

[0034] The water vapor collection structure provided by this invention provides an attachment structure for airborne water vapor by setting up a condenser-shaped pipe 1 for connecting irrigation pipe 2 and drip irrigation pipe 3. The condenser-shaped pipe 1, connected to irrigation pipe 2 and drip irrigation pipe 3, maintains a low temperature under the action of flowing irrigation water, which is beneficial for condensing and liquefying water vapor in the contacting air and converging it into a water flow. The water vapor condensed and liquefied by the condensate recovery assembly 6 located below the condenser-shaped pipe 1 is collected by a funnel 7 and recovered through a recovery pipe 8. This allows for the collection of airborne water vapor for secondary use, improving the utilization rate of irrigation water, and simultaneously reducing the humidity in the greenhouse, which is beneficial for plant growth. This solves the technical problem that existing greenhouses use ventilation to control humidity, resulting in water resources being lost to the outside in the form of vapor, which prevents the full utilization of greenhouse water resources.

[0035] In an optional embodiment of the present invention, the water vapor collection structure includes a zigzag-shaped connecting pipe 9, which is disposed between the water outlet 5 and the drip irrigation line 3, and bends towards the side near the collection funnel 7 to collect the water flowing up from the condensate drain line 1 onto the zigzag connecting pipe 9 and the water droplets formed by the water adhering to the zigzag connecting pipe 9 into the collection funnel 7. In an optional embodiment of the present invention, the zigzag connecting pipe 9 includes a bend head located above the collection funnel 7 to facilitate the collection of water droplets or water flow condensed from water vapor through the pipe wall of the zigzag connecting pipe 9. In another embodiment of the present invention, the irregular connecting pipe 9 includes two bends arranged opposite to each other to form a Z-shaped structure. One bend is located above the manifold funnel 7, and the other bend is located at the connection point between the irregular connecting pipe 9 and the drip irrigation line 3, thereby increasing the inclination angle of the pipe extending from the irregular connecting pipe 9 to the manifold funnel 7, which is beneficial for collecting and merging condensate vapors adhering to the pipe wall of the irregular connecting pipe 9.

[0036] In a further optional embodiment of the present invention, the bending angle formed by the axial extension line of the bend of the irregular connecting pipe 9 and the horizontal plane is α. Preferably, α is 45°. At this time, the setting of the α angle value is more conducive to the collection of condensed water vapor.

[0037] In an optional embodiment of the present invention, the surface of the condensate drain pipe 1 is provided with an anti-corrosion coating layer to slow down the corrosion of the condensate drain pipe 1 under high humidity conditions in the greenhouse, thereby improving the service life of the condensate drain pipe 1 and ensuring that the collected condensate water vapor is clean enough for secondary irrigation. In a further optional embodiment of the present invention, the surface of the condensate drain pipe 1 is a non-smooth structure to facilitate the adhesion and condensation of condensate water vapor. Preferably, the surface of the condensate drain pipe 1 is a frosted surface, or the surface of the condensate drain pipe 1 is provided with structural grooves or protrusions. These structural grooves and protrusions preferably extend along the vertical surface of the condensate drain pipe 1 so that the attached condensate water vapor can converge under its own gravity.

[0038] In an optional embodiment of the present invention, the water vapor collection structure includes a water storage tank 10, which is connected to a recovery pipeline 8 to store and allow the water recovered by the water vapor recovery structure to settle.

[0039] A second aspect of the present invention provides an irrigation system comprising an irrigation pipeline 2, a drip irrigation pipeline 3, and a water vapor collection structure according to any of the above-described embodiments. Multiple water vapor collection structures are equally spaced between the irrigation pipeline 2 and the drip irrigation pipeline 3 to collect water vapor from equal-area sections within a greenhouse. The water vapor collection structures, positioned between the irrigation pipeline 2 and the drip irrigation pipeline 3, not only utilize irrigation water for condensation and cooling of the drainage pipeline 1, but also bring them closer to the crops and soil / irrigation water surface where water vapor is generated after irrigation. This facilitates the condensation and collection of water vapor from the high humidity in the greenhouse air, thereby improving the efficiency of water vapor condensation and recovery.

[0040] In one optional embodiment of the present invention, the irrigation pipe 2 is disposed above the drip irrigation pipe 3, wherein the condensate drain pipe 1 is disposed vertically between the irrigation pipe 2 and the drip irrigation pipe 3. In another optional embodiment of the present invention, the condensate drain pipe 1 is disposed vertically at an angle β between the irrigation pipe 2 and the drip irrigation pipe 3. The above-mentioned arrangement with an angle β is suitable when the surface area of ​​the condensate drain pipe 1 is large, while the distance between the irrigation pipe 2 and the drip irrigation pipe 3 is small. The angle of the angle β can be adaptively adjusted according to specific site requirements.

[0041] In an optional embodiment of the present invention, the recovery pipeline 8 is connected to the irrigation pipeline 2, or the recovery pipeline 8 is connected to the drip irrigation pipeline 3, so as to apply the recovered condensate vapor to the irrigation of crops in the greenhouse. In a further optional embodiment of the present invention, the recovery pipeline 8 is connected to the irrigation pipeline 2 or the drip irrigation pipeline 3 through a water storage tank 10, and a one-way valve 11 is provided between the water storage tank 10 and the irrigation pipeline 2 or the drip irrigation pipeline 3 to prevent irrigation water in the irrigation pipeline 2 or the drip irrigation pipeline 3 from flowing back into the water storage tank 10. Further optionally, a delivery pump 12 is provided between the water storage tank 10 and the irrigation pipeline 2 or the drip irrigation pipeline 3 to pressurize and deliver the water in the water storage tank 10 to the irrigation pipeline 2 or the drip irrigation pipeline 3 for irrigation.

[0042] The above description is merely a preferred / optional embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
