Tubular capacitive deionization desalting device

Abstract

The invention relates to a tubular capacitive deionization desalting device, which comprises a reactor main body (1). One end of the reactor main body (1) is equipped with a water inlet (14) for sewage containing charged particles, the other end of the reactor main body (1) is equipped with a water outlet (17), the water inlet (14) is equipped with a first electrode end plate (31), the water outlet (17) is equipped with a second electrode end plate (34), a water distributor (2) is disposed between the first electrode end plate (31) and the second electrode end plate (34), and a plurality of parallel electrode plates (32) are connected in series to the water distributor (2). The first electrode end plate (31) and the second electrode end plate (34) are fixed by a plurality of screw rods (4), by which the space between the two electrode end plates and the space between the electrode plates (32) can be adjusted.

Description

technical field [0001] The invention relates to a capacitive deionization device, in particular to a tube-type capacitive deionization and desalination device using circular electrode sheets. Background technique [0002] At present, the main water desalination technologies at home and abroad include thermal method, chemical method, membrane method and capacitive deionization 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] The capacitive deionization method has low cost, strong ant...

AI Technical Summary

Problems solved by technology

[0004] The present invention designs a tube-type capacitive deionization and desalination device, which solves the technical problem that the current capacitive deionization and deionization device has a fully sealed structure, and is large in size and heavy in weight, so it is extremely inconvenient to disassemble and replace. If the electrode needs to be replaced It must be replaced as a whole, which will cause waste and rising costs.
