Problems solved by technology

Solar "photovoltaic power generation" is a form of power generation that directly converts solar energy into electrical energy. The electrical energy generated by it is transmitted to the outside world in the form of direct current. Since the actual electrical load is mainly operated by alternating current, such as reverse osmosis water treatment equipment , in the process of actual use, it is first necessary to convert the direct current generated

Embodiment 1

[0010] In this embodiment, ordinary electrodialysis membrane stacks are selected for desalination of seawater. The electric energy generated by solar cells 1 with seven groups of power generation power of 250W is distributed after passing through the controller 2, and enters the electric energy of the entire electrodialysis device. 30% of the electric energy is transmitted to 70% of the electric energy directly acts on the electrodialysis membrane stack 5, and under the action of direct current, seawater desalination Fresh water is produced; during the electrodialysis process, a small amount of unused electric energy is input into the storage battery 4 for electric energy storage. Among them, the size of the electrodialysis membrane is 300mm×800mm, and the effective membrane area is 0.2m 2 , 30 sets of homogeneous anion and cation exchange membranes, in the process of electrodialysis seawater desalination, the average working current density acting on the electrodialysis membr...

Embodiment 2

[0012] In this embodiment, a three-compartment bipolar membrane electrodialysis membrane stack is selected, and seawater is used to prepare seven groups of acid and alkali. The electric energy generated by solar cell 1 with a power generation power of 250W is distributed through the controller 2 and enters the entire electrodialysis device. Electric energy, wherein 25% of the electric energy is transferred to the inverter 3 and converted into alternating current to make the bipolar membrane electrodialysis water pump work, and send the hardened seawater into the bipolar membrane electrodialysis membrane stack; 75% of the electric energy It acts directly on the electrodialysis membrane stack 5. Under the action of direct current, the anions in the hardened seawater enter the acid chamber and the H produced by the bipolar membrane. + Combined to generate acid, cations enter the base compartment and OH generated by the bipolar membrane - Combined to generate alkali; in the bipola...

Abstract

The invention belongs to the technical field of membrane method water treatment equipment and relates to a solar photovoltaic power generation water treatment device. According to the device, an electrodialysis membrane stack and an electrodialysis water pump are connected and assembled in an electrical information manner to form an electrodialysis device; a solar cell is fixedly connected with a controller; electric energy generated by the solar cell is distributed through a controller; the controller is connected with a storage battery, an inverter and the electrodialysis membrane stake respectively in an electrical information manner; 25-35 percent of electric energy is transferred into the inverter, the inverter converts the electric energy into alternating current for the electrodialysis water pump, and the utilization rate of the electric energy converted by the inverter is 90 percent; 65-75 percent of electric energy directly acts on the electrodialysis membrane stack to supply power, and the utilization efficiency of the electric energy is 98 percent; and excessive electric energy is controlled and transmitted to the storage battery for storage so as to be used when the sunshine is insufficient. The device is simple in structure, convenient to use, high in electric energy utilization efficiency and sufficient in power supply and can be used for desalinization of seawater and brackish water and clean production of acid and base.

Description

Technical field: [0001] The invention belongs to the technical field of membrane method water treatment equipment, and relates to a solar photovoltaic power generation water treatment device, which is used for environmental protection water treatment in solar power generation occasions. Background technique: [0002] my country is a country that lacks fresh water, and the distribution of fresh water resources is uneven. The places where fresh water resources are insufficient are places where electricity is relatively short, such as remote areas in the west, coastal islands and other places. In recent years, with the continuous improvement of people's living standards, and the island Development, these areas have higher and higher demands for improvement of drinking water resources, these areas are often rich in brackish water and sea water resources, and have abundant solar energy resources, so solar "photovoltaic power generation" can be used to generate electricity and water...
