Opening type capacitor deionization and desalting device

Abstract

The invention relates to an opening type capacitor deionization and desalting device. The opening type capacitor deionization and desalting device comprises a container body, wherein the container body is internally provided with a plurality of electrodes in parallel; a water inlet (121) is arranged at one end of the container body and a water outlet (122) is arranged at the other end of the container body; the position of the water inlet (121) is lower than the lowest ends of all the electrodes; the position of the water outlet (122) is higher than the topmost ends of all the electrodes; sewage to be treated enters from the water inlet (121) and penetrates through gaps among the plurality of electrodes, and anions and cations are adsorbed through the plurality of electrodes; finally, thesewage leaves away from the container body through the water outlet (122); finally, the opening type capacitor deionization and desalting device further comprises a cover plate (11); the cover plate (11) covers the container body; the cover plate (11) is provided with an air vent (111). The opening type capacitor deionization and desalting device provided by the invention does not need to be sealed and the requirements on voltage withstanding strength of the device are also greatly reduced, so that a lot of materials and processing cost are reduced and the assembling is more convenient and rapid.

Description

technical field [0001] The invention relates to a capacitive deionization device, in particular to an open capacitive deionization and desalination device without sealing. Background technique [0002] At present, the main desalination technologies at home and abroad include thermal method, chemical method, membrane method and electrosorption method. The investment and operation costs of the thermal method are very high, which is suitable for special industries, but not for general water and large-scale applications; the membrane method includes nanofiltration, ultrafiltration, reverse osmosis, etc., and its effluent water quality is better, but the investment is large and the operation The cost is high and there is secondary pollution; while the chemical method needs to consume a lot of acid, alkali and salt when regenerating, which has great pollution to the environment. [0003] During the working process of the capacitive deionization desalination system, the raw water ...

AI Technical Summary

Problems solved by technology

[0005] The present invention designs an open capacitive deionization and desalination device, which solves the technical problem that the current capacitive deionization device is airtight, and it is inconvenient to disassemble. If the electrode needs to be replaced, it must be replaced as a whole, which will cause Causing waste and rising costs
