Abstract

The invention discloses a rotary continuous capacitive deionizing desalting device. The device comprises a transmission system, a water feeding system, a capacitive deionizing system and an energy supply system; electrodes are driven to be switched among desalting areas, a sealing area, regenerating areas and dehydration areas through a conveyor belt; an adsorbing flow path is arranged between thetwo desalting areas, and ions in brackish water passing through the adsorbing flow path are adsorbed to the surfaces of the electrodes to achieve the desalting effect on the brackish water; a desorbing flow path is arranged between the two regenerating areas, the ions adsorbed by the electrodes are released in concentrated saline water again, and the purpose of regenerating the electrodes is achieved; through switching of the electrodes, the continuous desalting effect on the brackish water is achieved. According to the rotary continuous capacitive deionizing desalting device, by changing theworking structure of the capacitive deionizing desalting device, the purposes that the adsorbing flow path of the capacitive deionizing desalting device continuously desalts water, and continuous andstable purified water is obtained at an outlet end of the adsorbing flow path are achieved, and the desalting efficiency for capacitive deionizing is effectively improved.

Description

technical field [0001] The invention relates to desalination technology, in particular to a continuous capacitive deionization desalination device based on a rotating conveyor belt, which can be applied to the purification of waste water containing inorganic salts, the softening of hard water containing calcium and magnesium ions, and the drinking water containing heavy metal ions Purification, low-salinity surface water purification. Background technique [0002] Fresh water resources are a necessity for human life, and the shortage of its storage has become an urgent problem to be solved. If seawater or brackish water can be converted into pure water, it will effectively solve the problem of shortage of fresh water resources. [0003] The desalination technologies widely used in the world include distillation, electrodialysis, ion exchange and reverse osmosis. With the development of technology, reverse osmosis method (64%), multi-stage flash evaporation method (23%) and...
