Semiconductor-based cooling condensation vegetation drip irrigation device

Abstract

The present invention proposes a semi-conductor-based refrigeration condensation vegetation drip irrigation device. In the double-stage air induction module, a double-layer Venturi structure is adopted, combined with a fan to increase the air intake; in the refrigeration water intake module, the outer wall of the inner pipe at the cold end is set The semiconductor chip in the semiconductor chip module is connected to the circuit control module that can control the temperature of the inner tube at the cold end, so that the temperature of the inner tube at the cold end is kept within a reasonable range above the frost point temperature of water and below the dew point temperature, which solves the problem of cold The problem that the surface of the inner wall of the inner pipe at the end is easy to frost has greatly improved the water intake efficiency of the drip irrigation device; The set water pump is connected to the water pipe to realize drip irrigation; the drip irrigation device is powered by the electric energy obtained by the solar panel, and can run automatically for a long time, which is extremely suitable for vegetation drip irrigation in arid areas.

Description

technical field [0001] The invention belongs to the technical field of irrigation devices, and designs a drip irrigation device for refrigerating dew condensation vegetation. Background technique [0002] For semi-arid areas, green vegetation needs to be irrigated during the growth process, but the water resources in the area are scarce, and the transportation of water resources from other areas for irrigation is expensive. Therefore, air water intake systems are generally used to irrigate green vegetation. [0003] At present, the 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, which requires a large workload.

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
