Technical field
The invention belongs to water-treatment technology field, particularly a kind of softening water treatment system.
Background technology
Ion exchange softening water treatment is the water demineralization technique be most widely used at present, namely reduces water hardness.Softening water treatment technology comprises three parts, and namely ion-exchange container, regenerator add and positive backwash process.Softening ultimate principle is ion-exchange, the main body exchanged is ion exchange resin, Ca2+, Mg2+ in water cements out by it, because water hardness is primarily of calcium, magnesium composition, therefore generally adopt Zeo-karb, along with the increase of Ca2+, Mg2+ in resin, the usefulness that resin removes Ca2+, Mg2+ in water reduces gradually.Therefore, after softening water treatment facility uses for some time, the general sodium-chlor that uses carries out manipulation of regeneration to resin, recovers the usefulness of resin, improves the work-ing life of resin.
For sodium ion exchange sofening treatment, be by former water by sodium form Zeo-karb, the hardness components Ca2+ in water, Mg2+ are exchanged with the Na+ phase in resin, thus Ca2+, the Mg2+ in planar water, water are softened.Namely water is by after Na-ion exchanger, and Ca2+, Mg2+ in water are replaced as Na+.After sodium ion exchange resin lost efficacy, for recovering its exchange capacity, manipulation of regeneration will be carried out.Regenerator is sodium chloride aqueous solution.Through above-mentioned process, resin can recover original exchange capacity.
Existing regeneration techniques, is generally by being dissolved in salt box by Industrial Salt, then enters softening filter.Because Industrial Salt exists a certain amount of impurity, and solute effect in salt box is poor, and the regenerative brine quality obtained is lower, affects the life-span of regeneration of ion-exchange resin time and resin.
Summary of the invention
The object of the present invention is to provide a kind of softening water treatment system rational in infrastructure, salts solution impurity in dissolved salt pond and tiny non-dissolved salt particle filtration can be removed by it, improve the salts solution quality entering softening filter, thus strengthen the effect of resin regeneration further.
The object of the invention is by such technical scheme realize, it comprises the dissolved salt pond connected by pipeline successively, first valve, salt transferpump, tensimeter, salt strainer, salt box, second valve and softening filter, described salt strainer, salt box and softening filter include tank body, filtering net is horizontally arranged with in the tank body of described salt strainer, be filled with below described filtering net is highly 800mm, particle diameter is the quartz sand filter media of 1-2mm, described softening filter be provided with former water inlet and produce water out, described former water inlet is connected by pipeline with former water end (W.E.), described product water out is connected by pipeline with product water end (W.E.).
The former water of former water end (W.E.) enters in softening filter through former water inlet.Be provided with resin in softening filter, enter into the former water in softening filter and resin generation ion exchange reaction.The main body that ion-exchange occurs is resin, and Ca2+, the Mg2+ in water cements out by it.Because water hardness is mainly reflected in containing Ca2+ and Mg2+ in water, therefore generally adopt positive resin, along with the increase of Ca2+, Mg2+ in resin, the usefulness that resin removes Ca2+, Mg2+ in water reduces gradually.
Now, Industrial Salt is poured into dissolved salt pond, Industrial Salt is dissolved for sodium chloride aqueous solution.After Industrial Salt dissolves, open the first valve and ejector priming, the sodium chloride aqueous solution in dissolved salt pond by the first valve, and through salt transferpump, is delivered in salt strainer.Tensimeter is used for the pressure in real-time display pipes.Owing to being mixed with impurity in Industrial Salt, and the impurity in Industrial Salt is not processed in the process of dissolving.This salt strainer can by the impurity in sodium chloride aqueous solution, and tiny non-dissolved salt particle filtration is got rid of.Particularly, in the tank body of salt strainer, the fine particulate filter in sodium chloride aqueous solution falls by the filtering net of arranged transversely.Be provided with quartz sand filter media below filtering net, utilize the interception function of quartz sand filter media, precipitating action, inertia effect and adsorption, reduce the content of suspended substance in sodium chloride aqueous solution.
Sodium chloride aqueous solution through filtering enters in salt box through pipeline, then enters in softening filter by the second valve, carries out manipulation of regeneration to resin.In Na+ in sodium chloride aqueous solution and resin, Ca2+ and Mg2+ reacts, Ca2+ and Mg2+ namely in polymeric adsorbent, resin can recover original exchange capacity, and former water is softened.
Further, described filtering net is nylon filter.
Further, the particle diameter of described filtering net is 30 orders.
Further, the pipeline between described salt strainer and softening filter is provided with ejector.
Further, described tank body is the hermetically sealed tank of stainless steel.
Further, described first valve and the second valve are magnetic valve.
Owing to have employed technique scheme, the present invention has advantage rational in infrastructure, salts solution impurity in dissolved salt pond and tiny non-dissolved salt particle filtration can be removed by it, improve the salts solution quality entering softening filter, thus strengthen the effect of resin regeneration further.
