Novel capacitive deionization treatment device

Abstract

The invention relates to a novel capacitive deionization treatment device. A spraying device is arranged at the top of a device body, and four pieces of organic glass are arranged at the side edge part. A water inlet is formed in the lower left side of the side edge part, and a fresh water outlet is formed in the upper right side of the side edge part. The left organic glass, a sealing washer anda negative plate are fixed through studs. The right organic glass, a sealing washer and a positive plate are fixed through studs. A first channel, a second channel... an nth channel are formed in thedevice body at intervals through stainless steel base plates, and a Z-shaped circulation channel is formed among the first channel, the second channel... the nth channel. The stainless steel base plates and the organic glass on the side edges are fixed through studs, two same-stage electrode plates are arranged on the two sides of the same stainless steel base plate, the two same-stage electrode plates are negative plates or positive plates, the number of the negative plates and the number of the positive plates are both n, and the negative plates and the positive plates are arranged in the device body in parallel in a staggered mode.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a novel capacitive deionization treatment device. Background technique [0002] With the rapid development of the world economy, the discharge of saline wastewater in the fields of industry and agriculture is becoming more and more serious. If the saline wastewater is discharged directly without treatment, it will not only lead to salinization of the land, but also lead to the death of a large number of organisms in the water. Traditional desalination technologies include distillation, ion exchange, reverse osmosis, and electrodialysis, which have a series of problems such as high operating costs and easy clogging. In recent years, a new type of capacitive deionization technology is considered to be the most promising desalination technology because of its low operating cost, no secondary pollution, low energy consumption, and high efficiency at room temperature.

Problems solved by technology

[0006] In order to overcome the problems existing in the prior art, the present invention provides a new type of capacitive deionization treatment device, which solves the shortcomings of poor flow performance and small adsorption capacity inside the equipment, especially for the long regeneration time during backwashing in the desorption stage. The problem of low salt removal efficiency leads to a capacitive deionization device with stable internal flow performance, controllable desalination rate, short regeneration time and high treatment efficiency.
