Photovoltaic solar reverse osmosis desalination device

Abstract

The invention provides a photovoltaic solar reverse osmosis desalination device. The device consists of a photovoltaic solar direct current power supply system and a reverse osmosis desalination system, wherein the photovoltaic solar direct current power supply system comprises a solar photovoltaic battery plate, storage batteries and a controller, wherein the output end of the solar photovoltaic battery plate is connected with the controller; and the storage battery set is connected with the controller bi-directionally. As the photovoltaic solar direct current power supply system is adopted to the device provided by the invention, a direct current drive is adopted to reduce the power loss caused by the inversion process and increase the generating efficiency of the photovoltaic solar power supply system and the investments of the photovoltaic solar power generating system and the inverter can be relatively reduced. The four-way reversing valve provided by the invention is characterized by comprising a motion valve; when the piston moves to a limiting position, the valve rod is pushed for conversion, thus the differential pressure recovery pump can switch to a working state automatically; and the adaptabilities of the flow and pressure of the system are good.

Description

technical field [0001] The invention relates to a reverse osmosis desalination device, in particular to a photovoltaic solar reverse osmosis desalination device. Background technique [0002] Water is the source of life, the lifeblood of social and economic development, and a precious and irreplaceable natural resource for human beings. With the continuous development of the economy and the continuous improvement of people's living standards, the demand for water is increasing, and the requirements for water quality are getting higher and higher. However, the shortage of water resources, the uneven distribution of time and space, and the excessive Exploitation, unrestrained waste, random pollution and poor management have exacerbated the already tense contradiction between supply and demand of water resources, and the problem of water shortage has become a worldwide problem. [0003] Seawater desalination, as an open-source technology, can increase the total amount of local...
