A self-supply water system for agricultural greenhouses based on a fluidized bed

Abstract

The invention belongs to the technical field of agricultural greenhouses, and discloses an agricultural greenhouse self-water-supply system based on a fluidized bed. The system comprises an optical subsystem and a water making subsystem. The water making subsystem comprises a solar heat absorption plate of a hollow structure inside, the fluidized bed, a draught fan arranged at the other end of thesolar heat absorption plate, a condensing pipe arranged at the tail end of the fluidized bed, and a water collecting tank arranged at the lower end of the condensing pipe, wherein a water absorptionmaterial is arranged in the fluidized bed, the water collecting tank is connected with the draught fan through an air pipe, and then the whole water making subsystem forms a closed loop. The inventionfurther discloses a method corresponding to the system. By means of the mechanism that the energy of infrared light in solar light is used as the heat energy for dewatering an adsorption material anddesorbed water is converted into vapor to be collected, the problem that desorbed water cannot be sufficiently collected in existing problems is solved, and the agricultural greenhouse self-water-supply system has the advantages of being compact in structure, simple in operation process and high in solar energy utilization rate.

Description

technical field [0001] The invention belongs to the technical field of greenhouse water supply, and more specifically relates to a self-supply water system for agricultural greenhouses based on a fluidized bed. Background technique [0002] With the continuous progress of the society, the traditional agricultural production mode can no longer meet the needs of the development of modern civilization, and the new type of facility agriculture is sought after by people in the industry. The so-called agricultural equipment is actually greenhouse facilities, which are not limited by time and space, and can carry out agricultural production in special environments such as plateaus, deep mountains, and deserts. China is a large agricultural country, and farmers account for more than half of the total population. The space for agricultural innovation and application is infinite. The agricultural equipment industry has moved from behind the scenes to the front of the stage. Throughou...

Problems solved by technology

[0005] Aiming at the above defects or improvement needs of the prior art, the present invention provides a self-supplied water system for agricultural greenhouses based on a fluidized bed. The mechanism of converting attached water into water vapor for collection solves the problem that the desorbed water cannot be fully collected in the existing problems. At the same time, the remaining light is used for the growth of plants, thus realizing the stepwise utilization of sunlight. Realized the self-supply water function of the greenhouse, alleviating the problem of water shortage
