Condensate deconductivity

Condensate fine treatment <desalting technology>

Sisven's condensed water treatment deep demineralization technology uses a mixed ion exchanger (mixed bed), which mixes a certain ratio of anion and cation exchange resins into the same exchange device to exchange and remove cations and anions in the condensation except. After the condensate is further desalinated in the mixed bed, the ultra-pure water required for medium and high pressure boilers can be satisfied. Because condensate has the characteristics of high operating temperature and pressure, large flow, and low salt content, Severn's condensate condensate precision treatment deep demineralization technology uses a high-speed mixed bed that is a high-speed mixed bed. High speed mixed bed resin is different from dry mixed bed resin. It should have high mechanical strength and anti-impact impact in terms of physical properties. In terms of hydraulic performance, it requires uniform particle size, good hydraulic delamination performance and low fluid resistance loss. In terms of chemical properties, there must be a faster exchange speed and a higher working exchange capacity.

Condensate fine treatment in addition to conductance

Resin is a polymer compound with a network structure with active groups. There is a moving part in the resin. It can be ionized when moving with water and can move within a certain range. So when an aqueous solution containing salts passes through the resin, the resin can exchange the salt in the water. The cations in the condensed water are removed by reaction with the cation resin, and the anions are removed by reaction with the anion resin.

The more the resin has a selective ion band, the more easily it will be absorbed.
Ions with the same charge are more easily absorbed by large atomic numbers.
For strongly acidic cation resin: Fe3 +> AL3 +> Ca2 +> Mg2 +> Na +> H +
For strongly basic anion resin: S042 +. > HSO4-> N0-> Cr-> 0H-> HCO3-

Ionic reaction when the resin has reversible exchange:
Anion exchange reaction: RH + Na + = RNa + H +
Anion resin exchange reaction; ROH + Cl- = RCl + OH-
Ionic reactions during regeneration:
Anion resin: RNa + H + = RH + Na + Anion resin: RCI + OH- = ROH + Cr-

The Siven Condensate Refined Mixed Bed System consists of a high-speed mixed bed, a resin trap, a recirculation pump, and a bypass system. In the initial stage of the unit startup, when the iron content of the condensate exceeds 1000 μg / L, it will not enter the condensate fine treatment device and will be discharged directly through the bypass 100%. After the normal operation, if the initial effluent of the mixed bed does not meet the requirements, it needs to be circulated by the recirculation pump until the mixed bed effluent is qualified to supply water to the system.
