Solar energy sea water desalinating warmhouse

Abstract

The present invention discloses a solar seawater desalinating greenhouse, comprising a main greenhouse, which is used for cultivating crops. A seawater distillation top level is added and arranged on the front part of the top of the greenhouse. An inner layer of the seawater distillation top level adopts a wavelength selective color plastic plate. The cover face of an outer lay of a roof adopts a translucent panel. A freshwater water collecting groove is arranged at the gutter in an inner layer of the roof. The freshwater collecting groove is communicated with a freshwater storage pool through a pipeline. A seawater storage pool, which is used for pumping and storing the seawater is connected and fixed on a jetting pipe in the inner layer of the roof through a water feeding column. Jetting holes are opened on the two sides of the jetting pipe. The present invention integrates the solar seawater desalinating device and the environmental controlled greenhouse in a whole, which is suitable for producing freshwater used in agriculture; in addition, the present invention also has the functions of sun shading and cooling, which can be used for desalinating the seawater and cultivating crops. The present invention can satisfy the need for vegetables supply and the drinking water for men and animals in coastal areas, islands, desert alkali region and so on where have seawater or brackish water but lack of freshwater resource.

Description

technical field [0001] The invention relates to the technical field of greenhouse design for agricultural production, in particular to a greenhouse which integrates solar energy and seawater desalination technology and is suitable for planting crops in areas where freshwater resources are scarce. Background technique [0002] Carry out agricultural production in hot and dry areas, due to evaporation, about 80% of the supplied fresh water will be lost, which is very uneconomical. Therefore, in order to do a good job in agricultural production, it is necessary to control the ambient temperature in the greenhouse. At present, most greenhouses usually use "humidity". The curtain fan device uses the evaporation of water to reduce the temperature, that is, a large axial fan is installed on one side of the greenhouse, and a wet curtain is installed on the opposite side. The wet curtain is a porous honeycomb mat made of organic materials. Wet the mat well with fresh water. Even so,...

AI Technical Summary

Problems solved by technology

The experimental project has achieved certain results, but the seawater desalination device of this system uses the principle of vacuum evaporation, and has solar heat collection equipment independent of the greenhouse, three-stage vacuum evaporation cylinder, etc. The equipment is relatively complicated and the cost is relatively high
