Description
Technical field
The utility model is established and is related to a kind of cationic ion-exchange resin iron poisoning recovery treatment facility, particularly relates to the automation recycling treatment facility being applicable to directly reclaim the poisoning cleaning acid pickle of resin iron ion.
Background technology
Cationic ion-exchange resin is removed in the water treatment facilities of calcium ions and magnesium ions in water in station boiler demineralized water, Industrial Boiler demineralized water and pure water production etc. and is widely used.Resin is in use because the pollution of objectionable impurities iron ion is adsorbed, ion exchange resin exchange capacity is caused to decline, the phenomenon that appearance cycle water-making ability reduces gradually, resin outward appearance presents the color of rubescent blackout, and it is poisoning that this phenomenon is called as cationic ion-exchange resin iron ion.After resin generation is poisoning, it is with being twice in resin volume that method is sent out in conventional use, and the salt acid soak of concentration 10-15%, makes the iron ion that resin adsorbs be replaced by hydrogen ion and exclude, again recover the exchange capacity of resin.But there are the following problems for the method: one is that resin poison is very dark, the hydrochloric acid solution amount being twice in resin volume is inadequate, needs the hydrochloric acid solution being several times as much as resin volume iron ion could be eluted.Two be cleaning time without purpose-built washing equipment, the destruction of tank body place where troops were originally stationed sheath can be caused with the hydrochloric acid solution cleaning of 10-15% in former interchanger, three is that hydrochloric acid after soaking and washing in acid pickle is still very high, the inside is mingled with a large amount of iron ion and cannot reuse goes out of use, these acid waste waters are discharged in environment without process, not only can cause water body or soil acidification by corrosion failure sewer, ecological environment is worked the mischief, and hydrochloric acid is emitted waste resource in vain.
Trundle bed layer ion exchange technique is the sour retardation utilizing strong base anion resins, strong alkalinity anion acid recovery resin is filled with in trundle bed layer ion-exchanger, trundle bed layer ion-exchanger works with two step circulation patterns, the first step of circulation is up stroke, acid after filtration flows through resin bed by pump, free acid is adsorbed by resin particle, and the iron ion in solution flows out resin bed then unblockedly, and this step is continued until that resin bed adsorber acid is saturated.Second of circulation is down stroke, and the pure water in pure water tank flows through resin bed from the top down by pump, and according to the concentration being applicable to the acid being recycled to descaling bath, with pure water, acid is got off from desorption resin, this step is continued until resin bed holomorphosis.
Resin cleaning recovery is carried out in resin rinse bath.Resin rinse bath material is acidproof polypropylene, stir at high-pressure blast after putting into toxiresin and under salt acid soak, complete the ion-exchange of resin, the iron ion displaced is got rid of by trundle bed layer ion-exchanger, pure acid returns to resin rinse bath, complete subsequent exchange with the iron ion not occurring to replace that ion exchange resin adsorbs to react, iron ion on such resin is slowly progressively removed, and resin regains exchange capacity.Resin after recovery is discharged by clean recovery resin pipeline.
