Photovoltaic and photothermal saline-alkali water treatment device for saline-alkali land

Abstract

The invention belongs to the field of photovoltaic and photothermal technology and particularly relates to a photovoltaic and photothermal saline-alkali water treatment device for a saline-alkali land. The saline-alkali water treatment device for the photovoltaic and photothermal saline-alkali land is used for distilling saline-alkali water, and comprises a tank body for holding the saline-alkaliwater and a solar heat collection piece which is communicated with the tank body to form a circulation treatment loop of the saline-alkali water and used for heating the saline-alkali water in the circulation treatment loop to distill the saline-alkali water in the tank body. The tank body is provided with an inlet of the saline-alkali water, an outlet of steam and a recovery mouth. The saline-alkali water treatment device of the invention is provided with the solar heat collection piece; the solar heat collection piece is communicated with the tank body to form the circulation treatment loopof the saline-alkali water; the saline-alkali water in the circulation treatment loop is heated to distill the saline-alkali water in the tank body; the water of the saline-alkali water is continuously volatilized and discharged from the outlet of steam; and the saline-alkali water after the distillation treatment is discharged through the recovery mouth to form the circulation treatment of the saline-alkaline water. The device can conveniently continuously improve the saline-alkali water component in soil, can regulate concentration of saline-alkali water, has good improvement effect on the saline-alkali land, can save cost, can produce a main product saline-alkali component and a byproduct distilled water, and is good in economic benefit.

Description

technical field [0001] The invention belongs to the field of photovoltaic photothermal technology, and in particular relates to a saline-alkali water treatment device for photovoltaic photothermal saline land. Background technique [0002] With the implementation of the photovoltaic policy, the construction of photovoltaic power stations is becoming more and more frequent, and everyone's requirements for the materials needed for the construction of photovoltaic power stations are also getting higher and higher. How to reduce the construction cost of the power station and extend the operation period of the power station has become one of the focuses of everyone's attention one. Saline-alkali land can be used as a photovoltaic power generation base. Saline-alkali land is a type of salt accumulation. It means that the salt contained in the soil affects the normal growth of crops. The fundamental reason for the formation of saline-alkali soil is poor water conditions. Therefore...
