Ion exchange equipment  离子交换设备
Ion exchanger mainly for water and high pure water preparation, in the pharmaceutical, chemical, electronics, paint, and beverage of high pressure boiler water supply
 and many other engineering fields has a very wide range of applications. And in recent years the introduction of the reverse osmosis device to compare, with removal
of ions and thoroughly, pretreatment requirements low, the equipment cost is cheap and so on. In the preparation of high pure water, ion exchange technology in no
replacement equipment. Inlet total salt content in 400mg / L below, according to the different requirements of users, the effluent quality in 1.0-0.2us / cm. If the inlet total
salt content in 500mg / L, with electrodialysis combined desalting, effluent quality higher. Our company can provide users a separate engineering design, auxiliary and
installation commissioning, formulate rules and so on.

Basic principle

Using ion exchange method, can make the water in ion cation and anion removal, sodium chloride ( NaCl) represents the water inorganic salt water desalination basic
reaction can use the following equation : the way of expression

1. cation exchange column ( cation bed) : R-H+Na + - R-Na-H +

2. anion exchange column ( anion bed) : R-OH+Cl -- R-Cl+OH -- the album

3. cation and anion exchange column series later referred to as the complex bed, its total response can be written as:

RH+ROH+NaCl - RNa+RCl+H2O album album

This can be seen, the water NaCl album called were resin on H + and OH are replaced, and the reaction product only.

It reached the removal of salt effect

Hybrid ion exchange column ( bed ) : mixed bed is the positive and negative resin according to a certain percentage (usually 1: 2, so that Yang,

At the same time to achieve the exchange of anion resin finish and regeneration) into the mixing column and into, in fact it together into the water of the H +

And OH immediately generates ionization degree very small water molecules ( H2O), there is almost no cation bed or anion bed exchange is generated by the inverse AC

Change the phenomenon, so you can make the exchange reaction was very thorough, and mixed bed effluent quality was better than that of the positive and negative bed series

Composition of compound bed can achieve the water quality, can produce a high purity product water.

Equipment characteristics

No top pressure system, simplifies the operation, low investment and low operation cost ;

The assembly of strong type bed, weak beds, bunk beds and other economic reasonable desalting process, get the best results ;

The design and operation flow of diameter 200-800mm < 15-20m / h, < 1000-3000mm 20-30m / h;

The regeneration rate than 200-800mm for 2m / h, < 1000-3000mm 5-7m / h;

The backwash velocity cation bed is 15m / h, anion bed for 8-10m / h;

Matters needing attention

In order to guarantee the water, reducing the times of regeneration, water salinity best in 500mg / L, exceeds the value, lead electric dialyzator is more reasonable.
When the anion and cation exchanger complex bed system, the water alkalinity (HCO3 content ) than 50mg / L in its intermediate set except CO2 for dealkalization is
more reasonable. The operating personnel. After the operation to repair service, the implementation of product lifetime technical support. The products are used in a
variety of water desalination, softening or industrial water and alkali treatment, it can effectively remove the water anions and cations to anion-cation exchanger and
carbon dioxide for the unit can be combinations of multiple complex bed desalting system can remove the dissolved salts, equipment control system and automatic valves, instrumentation are international quality products.
