Simple greenhouse crop evapotranspiration condensing irrigation system based on semi-conductor refrigerating pipe

Abstract

The invention discloses a simple greenhouse crop evapotranspiration condensing irrigation system. The system comprises a simple greenhouse, a condensing pipe, a cooling pipe laid at the lower portion of the simple greenhouse and buried under the ground, an irrigation pipe, a water pump and a reservoir, the irrigation pipe and the water pump are arranged in the simple greenhouse, the reservoir is arranged outside the simple greenhouse, the water pump is communicated with the reservoir through an irrigation water inlet pipe, the lower end of the inlet section of the condensing pipe penetrates through the cooling pipe and is connected with one end of a semi-conductor refrigerating pipe, the upper end of the inlet section of the condensing pipe stretches into the simple greenhouse, the lower end of the outlet section penetrates through the other end of the cooling pipe and is connected with the other end of the semi-conductor refrigerating pipe, and the upper end of the outlet section of the condensing pipe is arranged outside the simple greenhouse. The simple greenhouse crop evapotranspiration condensing irrigation system based on the semi-conductor refrigerating pipe is compact in structure, can efficiently collect and recycle crop evapotranspiration moisture and increase the utilization rate of greenhouse crop irrigation water.

Description

technical field [0001] The invention relates to a device for obtaining irrigation water from hot and humid air in a simple greenhouse, in particular to a simple greenhouse crop evapotranspiration and condensation irrigation system based on semiconductor refrigeration tubes. Background technique [0002] With the growth of population, the promotion of urbanization and industrialization and the aggravation of water pollution, the global water resources are becoming increasingly tense. my country's agricultural water consumption accounts for about 70% of the total water consumption. The existing agricultural water-saving technologies mainly transport water through channels and pipelines to reduce losses in the process of transportation and distribution. Utilization efficiency; In addition, the precise irrigation forecast technology based on intelligent algorithms and meteorological data can accurately forecast the irrigation water consumption of crops in different growth stages,...

AI Technical Summary

Problems solved by technology

More than 90% of the water consumed by farmland enters the atmosphere in the form of evapotranspiration, resulting in a waste of water resources, but the recovery and recycling of crop evapotranspiration water vapor have been neglected in existing research

[0003] Some existing water vapor condensation technologies use the temperature difference between the inside and outside of the greenhouse to condense the moisture in the air in the simple greenhouse, but because the water vapor in the simple greenhouse is often not saturated, and the temperature difference between the inside and outside of the greenhouse sometimes cannot meet the conditions for condensation of wet and hot water in the greenhouse. Therefore, the water collection effect is poor
