混合离子交换器
Mixed of ion exchange
使用说明书
Operating Instruction
一、工艺原理Technical principle
本公司生产的混合离子交换器(简称混床),在脱盐水工程中,用于二级脱盐水的制备,被处理的水由上向下流经按一定的比例配比装填并混合形成的强酸、碱树脂层来制取成品水。
均匀混合的树脂层中,阳树脂与阴树脂紧密地交错排列,每一对阳树脂与阴树脂颗粒似于一组复床,混床就象无数组串联运行的复床。
通过混合离子交换后进入水中的氢离子与氢氧离子会立即生成电离度很低的水分子(H20),很少可能形成阳离子或阴离子交换时的反离子,使交换反应进行的十分彻底,因而能制取纯度相当高的成品水。
0ur company produces the mixed ion exchanger (referred to as ") of the mixed bed, in desalted water engineering, preparation for secondary desalting water, treated water by the down flow of mixed in certain proportion ratio of loading and the formation of acid, alkali, resin layer to manufacture the finished water. Evenly mixed resin layer, with Yin Yang resin resin tightly staggered, each pair of Yang Yin resin particles and resin on a set of double bed, mixed bed, like countless group of double bed series operation. After ion exchange in the water by mixing hydrogen ion and
hydroxide ion will immediately generate low degree of ionization of water molecules (H20), less likely to form the cation or anion exchange of ions, make the exchange reaction of very thoroughly, thereby making high purity of the finished water.
混床的再生工艺较阳、阴床的再生工艺复杂,混床树脂层失效后,需先对床中树脂进行反洗分层,使阳树脂与阴树脂彻底分离,然后分别对阳、阴树脂进行再生、清洗、恢复交换能力并均匀混合,方可继续投入运行。
Mixed bed regeneration process is cation exchanger、anion exchanger regeneration process complex, mixed bed resin layer expires, should first to backwashing stratification of resin in the bed, make with cation resin and anion resin separation thoroughly, then respectively for cation resin 、anion resin regeneration, cleaning, restore the exchange capacity and mixing, may continue to put into operation.

新树脂的预处理The pretreatment of the new resin
新树脂中含有过剩的原料及其所带的杂质、反映不完全的产物等,当树脂与水、酸、碱
溶液接触时,上述这些杂质(如磺酸.胺类等)会进入溶液,从而沾污出水水质及影响树脂的工艺性能。
因此, 新树脂在使用之前应进行预处理,以除去新树脂表面的可溶性杂质。
处理方法需按照各种不同使用对象而定。
New resin contained in excess of raw material and with the impurities, which can reflect the incomplete products, such as when the resin when in contact with the water, acid and alkali solution, these impurities (such as sulfonic acid, amine, etc.) will enter the solution, thus contamination effluent water quality and the influence on the performance of the resin process. Therefore, the new resin should be pretreated before use, to remove the soluble impurities on the surface of the new resin. Processing methods need to be used according to different objects.
一般新树脂若用在食品或医药工业的水处理系统时,最好先用树脂体积2-3 倍的饱和食盐
水浸泡20 小时左右,用自来水冲洗到中性。
再用2-5%盐酸浸泡或低流速处理,以除去铁质,然
后用2-5%烧碱溶液浸泡或低流速处理,以去除树脂中的有机杂质,并清洗至出水化学耗氧量(COD)达到稳定值,最后用纯水冲洗至中性。
如阳树脂必须再以2-5%盐酸转型,然后用纯水洗到出水无氯离子。
对于阴树脂不必再转型,经过烧碱处理已成氢氧型。
If new resin commonly used in food or pharmaceutical industrial water treatment system, it's best to use resin volume 2-3 times saturated salt water soak 20 hours or so, rinse with water to neutral. With 2-5% hydrochloric acid soaking or low velocity of processing, to remove the iron, then use a 2-5% caustic soda solution soak or low flow processing, to remove the organic impurities in the resin, and cleaning to water chemical oxygen consumption (COD) to achieve the stable value, finally to neutral is washed with pure water. Such as Yang resin to transition with 2-5% hydrochloric acid, then wash with water to the water without chloride ions. Don't have to transition to Yin resin, treated with caustic soda has been into hydrogen and oxygen.
对用于一般水处理系统中的新树脂,只要用约50C的温水以5-10米/时的流速冲洗数小时
即可。
有条件时可采用碱性食盐水(1%NaoH+10%NaCI)浸泡或低流速处理,使其出水化学耗氧量COD 达到稳定值。
For the general new resin in the water treatment system, with about 50C warm water for 5-10 meters/when velocity flushing for hours on end. Alkaline salt water can be used under conditions (1% NaoH + 10% NaCl) soaked or low velocity, the water chemical oxygen consumption to stabilize COD value.
处理后的新树脂经过一个周期运行后的第一次再生时,酸碱用量应为正常再生时的1-2倍。
After processing the new resin after run a cycle of regeneration for the first time, alkali dosage should be 1 to 2 times normal regeneration.。
