Abstract

The invention relates to the technical field of water treatment and particularly relates to a modularized membrane capacitance deionizer which is provided with a water inlet pipe, a water outlet pipe,a power transmission line pipe and a plurality of arrayed CDI membrane component modules, wherein the bottom of each CDI membrane component module is provided with a water inlet, the top of each CDImembrane component module is provided with a purified water outlet, the water inlets of all the CDI membrane component modules are connected to the water inlet pipe, and the water purification outletsof all the CDI membrane component modules are connected to the water outlet pipe; each CDI membrane component module comprises a plurality of electrode pairs which are sequentially stacked from top to bottom; each electrode pair is composed of an anode plate layer, an anion exchange membrane layer, a screen layer, a cation exchange membrane layer and a cathode plate layer which are sequentially stacked from top to bottom; and the centers of the anode plate layer, the anion exchange membrane layer, the screen layer, the cation exchange membrane layer and the cathode plate layer in each electrode pair are provided with through holes serving as raw water channels. The modularized membrane capacitance deionizer has a simplified structure and increases the water treatment capacity.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a modular membrane capacitive deionization device. Background technique [0002] The development and application research of capacitive deionization technology is an important way to solve or alleviate the global crisis of fresh water resources. This technology has the advantages of low energy consumption, good purification effect, simple equipment structure, and no secondary pollution. According to different electrode structures, membrane capacitive deionization devices can be divided into plate-type capacitive deionization devices and roll-type capacitive deionization devices. Plate-type capacitive deionization devices have the advantages of simple structure, convenient installation, and simple operation and maintenance. [0003] At present, the existing plate-type capacitive deionization devices on the market use Z-shaped water flow to flow in series between the plates...
