Overview

Bipolar membrane equipment Bipolar membrane is a new type of membrane, usually a composite ion exchange membrane composed of an anion exchange layer and a cation exchange layer. A third layer can also be added between the anion and cation membranes to promote water dissociation, forming a three-layer structure consisting of anion exchange layer, cation exchange layer, and intermediate reaction layer. Under the action of a direct current electric field, water can be dissociated, producing H+and OH - on both sides of the anode and cathode membranes, respectively.

Product Details

　　 Bipolar membrane equipmentThe principle:

It is generally composed of an anion exchange resin layer (AL), a cation exchange resin layer (CL), and an intermediate layer.

1. Commonly used alternative names in the intermediate layer market: transition layer, catalytic layer, composite layer, interface layer, etc;

2. The thickness of the intermediate layer is generally within 10 * 10 ^ -9m (nanometer level), and it is related to the film making principle and process.

Under the action of a direct current electric field, the hydrolysis ionization between the anion and cation membrane composite layers is carried out to form H+and OH - ions, which undergo directional migration and pass through the cation exchange membrane layer and anion exchange membrane layer, respectively, serving as the system's H+and OH - ion supply sources. H+and OH - are mainly replenished in a timely manner through the dissociation of water in the transition zone, and the consumed water is replenished by the permeation of water from the surrounding solution into the middle of the membrane.

The design of bipolar membrane electrodialysis equipment is as follows:

1. The membrane stack adopts a multi-purpose design, and standard electrodialysis can be achieved by replacing the membrane plate and assembling the membrane.

2. 2-bedroom bipolar membrane and 3-bedroom bipolar membrane electrodialysis function.

3. The system has a cooling and heat exchange function, which controls the thermal efficiency generated by the current through the cooling system.

4. The system is equipped with online monitoring of flow rate, temperature, conductivity, etc., which can monitor changes in various parameters filtered by the system.

5. All pipeline valves are made of corrosion-resistant materials to avoid high salt or acid-base corrosion.

6. The rack adopts high anti-corrosion treatment to avoid high salt or acid-base corrosion; Configure mobile casters for easy mobility and transportation.
