+The technology of water and softening water is integrated, and produces H early stage
+The Na that water, later-stage utilization produce in earlier stage
+Type production of resins softening water has been accomplished comprehensive utilization.This technology has the raising plant factor, reduces discharging of waste liquid, reduces consuming, and characteristics such as reduce labor intensity.
Description
The present invention relates to a kind of method by the Zeo-karb treating water.
In general industry, especially in the petrochemical industry, need a large amount of softening water and deionized water, in industry, produce softening water and deionized water has several different methods, wherein modal, the method that generally adopts is an ion exchange method now.As the method for mentioning in " give water treatment " chapter 8, the production method of softening water is a resin cation (R.C.) through the salt R that regenerates
2Ca(Mg)+Cl of 2NaCl → 2RNa+Ca(Mg)
2Produce softening water with the work type resin RNa after the regeneration; 2RNa+Ca
++(Mg)
++→ R
2Ca(Mg)+2Na
+, the water Ca of the resin cation (R.C.) of flowing through
++Mg
++Be removed, promptly become softening water.The first step of producing deionized water is to produce H
+Water, H
+The production method Ji Shui of water and softening water is the same, just produces H
+Resin regeneration is with acid, R during water
2Ca(Mg2Na)+Cl of 2HCl → 2RH+Ca(Mg2Na)
2Produce H with the work type resin 2RH after the regeneration
+Water: 2RH+Ca
++(Mg
++2Na
+) → R
2Ca(Mg2Na)+2H
+The water Ca of resin cation (R.C.) flows through
++Mg
++Na
+Be removed, all change H into
+Water.
Increase water quality for many years, reducing consumption, reducing discharging of waste liquid, reduce labor intensity is that the water treatment worker pursues always.Some relatively effectively achievements have been obtained in this respect, as the counter-current regeneration of writing on " giving water treatment " P218～P224, moving-bed, the double bunk that thermopnore and " giving water treatment " P236 write all belong to the novel process of ion-exchanger, though each equipment is all had large improvement in one aspect and is improved, but H up to the present,
+Interchanger and Na
+Interchanger all is the single-minded equipment that is provided with respectively in industrial production, and by its purpose separately, and operations such as rule is carried out backwash respectively, just washes, regenerated, operation are gone round and begun again and back and forth carried out.Especially cation exchanger is when it removes Ca
++Mg
++Na
+Produce H
+During water, as long as Na
+Reach prescribed value and just claim to lose efficacy, will pass through backwash, regeneration, just operation such as wash and handle, put into operation then, this has just caused equipment, raw material, the waste of energy aspect and the discharging that has increased waste liquid.
The purpose of this invention is to provide a kind of H that in a covering device, promptly produces
+Water, the novel process of producing softening water again.
In order to achieve the above object, the present invention has adopted general cation exchanger, and is earlier that the Zeo-karb in the interchanger is good with acid regeneration, recovers its work type resin 2RH, and the raw water cation exchanger of flowing through is produced H early stage
+Water, the later stage is produced softening water.
The present invention finishes by following manner; Raw water is produced H by with the good cation exchanger of acid treatment (1)
+Water, this water enters H
+Water tank (3) is being produced H
+Constantly chemically examine Na in water in the process of water at cation exchanger bottom water sampling
+When content reaches prescribed value, close H
+Water flowing water Valve (6) is opened softening water outlet valve (7), makes softening water flow into softening water water tank (2).In producing the softening water process,, in water outlet, contain Ca at cation exchanger (1) bottom sample examination
++Mg
++Be that resin lost efficacy when reaching prescribed value, at this moment close softening water outlet valve (7).Cation exchanger after the inefficacy (1) is with HCl regeneration, through backwash-regeneration-recovery is used and put into operation once more after just washing.
In the present invention, when current behind cation exchanger (1), entering H
+Water tank (3) is preceding can to take off CO through one
2Device (5) is to reach the CO that removes in anhydrating
2, alleviate the burden of cation exchanger.
In the present invention, before softening water outflow cation exchanger (1) enters softening water tank, can the alkali change of water outlet be mixed, and remove portion C O through a mixing tank (4)
2
Method of the present invention is owing to made full use of system H
+The exchange capacity of the exhausted resin behind the water has made full use of system H
+Na in " inefficacy attitude " behind the water
+The type resin, thereby Zeo-karb can reach and reduce to consume without the salt direct production softening water of regenerating, and reduces discharging of waste liquid, a series of techno-economic optimization effects of simplified process equipment.
Figure one is process flow sheet of the present invention.(1) is cation exchanger among the figure.(2) be the softening water water tank.(3) be H
+Water tank.(4) be mixing tank.(5) for taking off CO
2Huge legendary turtle #) is H
+The water out valve.(7) be the softening water outlet valve.
The embodiment of the invention:
What this experiment was adopted is the cationic exchange coloum of φ 36, the stratabed 122 that strong positive resin rice is produced with U.S. rom Haars Co., Ltd, and that weak positive resin adopts is stratabed 84, resin ratio is 1: 1, each 500mm of floor height, the industrial HCl of reduction.
Experimental procedure:
1. handle Zeo-karb with HCl, make its type resin 2RH that resumes work.The resin of handling well is packed in the cation exchanger (1).
2. the general industry water is introduced in the cation exchanger (1) from top, the untreated process water cation exchanger (1) of flowing through is produced H
+Water.Open valve (6), H
+Water is through taking off CO
2Device (5) flows into H
+Water tank (3).
3. producing H
+In the process of water, constantly at the water sampling chemical examination of cation exchanger (1) bottom, Na in water
+When content reaches prescribed value, close H
+Mouth of a river valve (6) is opened softening water outlet valve (7), and softening water flows into softening water water tank (2) through mixing tank (4).
4. in producing the softening water process,, in water, contain Ca at cation exchanger (1) bottom sample examination
++Mg
++Be that resin lost efficacy when reaching prescribed value.At this moment close softening water outlet valve (7).
5. the Zeo-karb after losing efficacy is regenerated in interchanger (1) with HCl, through backwash-regeneration-recovery is used and put into operation once more after just washing.
Experimental result sees Table one.
Our H as can be seen from experimental result
+-Na
+Combining water treatment technique is at system H
+Water quality and single H in the stage of water
+The water ion exchange process is compared the water quality basically identical.At Na
+The switching phase water hardness is qualified, and can reduce saltiness and alkali change.The alkali change of softening water is reduced to 1.13mmol/L by 4.6mmol/L and has been descended 76%, and corresponding saltiness has descended 58%.See that from utilization ratio, the exchange capacity of resin of acid corresponding raising has all been arranged.
