Semiconductor-based refrigeration condensation vegetation drip irrigation device

Abstract

The invention provides a semiconductor-based refrigeration condensation vegetation drip irrigation device. In a two-stage air inducing module, a double-layer venturi structure is adopted, and the air inlet amount is improved by combining with a fan; in a refrigeration water taking module, a semiconductor chip in a semiconductor chip module arranged on the outer wall of a cold-end inner pipe is connected with a circuit control module capable of controlling the temperature of the cold-end inner pipe, so that the temperature of the cold-end inner pipe is kept in a reasonable interval above the frost point temperature and below the dew point temperature of water; the problem that the surface of the inner wall of the cold-end inner pipe is prone to frosting is solved, and the water taking efficiency of the drip irrigation device is greatly improved; a flow guide column in the cold-end inner pipe collects water obtained through refrigeration into a water storage tank in a water storage drip irrigation module, and a water pump arranged in the water storage tank is connected with a water conveying pipe to achieve drip irrigation; and the drip irrigation device is powered by electric energy obtained by a solar panel, can automatically run for a long time, and is extremely suitable for vegetation drip irrigation in arid regions.

Description

technical field [0001] The invention belongs to the technical field of irrigation devices, and designs a cooling dew condensation vegetation drip irrigation device. Background technique [0002] For semi-arid areas, green vegetation needs to be irrigated during the growth process. However, water resources in this area are scarce, and the cost of transporting water resources from other areas for irrigation is high. Therefore, air water intake systems are generally used to irrigate green vegetation. [0003] At present, air water intake technology is mainly divided into: adsorption analysis method and refrigeration condensation method. At present, the water intake device of the adsorption analysis method needs to install a light-transmitting cover during the day and remove it at night. The workload is heavy. The replacement cycle of the adsorbent is 6 months, and the maintenance cost is high. At present, there are the following problems in the water intake device of cooling c...

Problems solved by technology

At present, the water intake device of the adsorption analysis method needs to install a light-transmitting cover during the day and remove it at night. The workload is heavy. The replacement cycle of the adsorbent is 6 months, and the maintenance cost is high.

At present, there are the following problems in the water intake device of cooling condensation method relying on semiconductors: relying on natural air intake, the incoming air is less, that is, the air with high humidity is less, so the water production speed is slow; on the surface of the semiconductor cold end fins, it is easy to form Film condensation, the low heat transfer coefficient makes the condensation speed slow. In addition, the droplets produced by this condensation method are not easy to fall off and collect, and are easy to frost, which affects the subsequent condensation of water vapor that continues to enter, so the water production is low; It is used for fresh water production and has a single working mode. It lacks specific designs suitable for realistic scenarios such as sandy land afforestation, so its practical application value is not great
