Sustainable capacitive deionization seawater desalination system

Abstract

The invention discloses a sustainable capacitive deionization seawater desalination system, which includes multi-layer flow channels, wherein a top cover is installed on the top of the flow channels located at the top, and the structures of the flow channels located in the odd-numbered layers and the even-numbered layers are respectively the same, and the odd-numbered The laminar flow channel and the even-numbered layer flow channel are not connected to each other. The flow channel includes a flow bearing plate and a gasket. Both ends of the gasket are provided with electrode sheets. The gasket can be embedded in the channel of the flow bearing plate. There is at least one set of drainage gaskets on the gasket, a pair of water-proof gaskets distributed diagonally at the corners of the gaskets, and gasket flow channel holes are arranged on the gaskets outside the water-proof gaskets. The flow bearing plate is provided with a direct current hole corresponding to the gasket flow channel hole, and the flow channel hole is provided on the other diagonal of the flow bearing plate. The invention uses the gasket as the support of the flow channel, and uses the gasket to process the water diversion channel, which reduces the processing difficulty and cost of the CDI module, not only reduces the operation complexity, improves the water purification efficiency, but also saves the economic cost.

Description

technical field [0001] The invention relates to a deionized seawater desalination system, in particular to a sustainable capacitive deionized seawater desalination system. Background technique [0002] The problem of fresh water resources has always been one of the important environmental issues. Water is one of the essential resources for the development of industry and agriculture. However, with the development of industrial technology, fresh water sources have been greatly damaged, and the fresh water resources available to humans are becoming less and less. Therefore, no matter from the perspective of environmental protection or industrial development. How to better obtain fresh water is an important research direction. [0003] At present, in the known seawater desalination methods, they are mainly divided into: distillation method, multi-effect steam method, reverse osmosis membrane method, and electrodialysis method. However, the distillation method consumes a lot ...

AI Technical Summary

Problems solved by technology

However, the distillation method consumes a lot of energy, the multi-effect flash method needs to deal with the scale regularly, and the operation is relatively complicated. The reverse osmosis membrane method and the electrodialysis method require a large investment, and the service life of the membrane is limited and cannot be reused.

Now, (for example, patents 201610574749.6 and 201010543910.6, etc.) use the characteristics of capacitive adsorption particles to design a capacitive deionization seawater desalination system CDI, but the flow channel is single and cannot continuously purify water
