Abstract
The utility model relates to an alkalinity-decreasing softener regenerated by regenerated waste liquid, which is filled with positive and negative layers of ion exchanging resins. The height of the positive resin layer is not lower than 1.2m; a main pipe branch pipe-type middle liquid drainage and water intake apparatus is installed on a plane surface which is approximately adjacent to the boundary surface of the negative and the positive resins; the alkalinity of influent water can be decreased when influent water passes through the upper chlorine type negative resin downward, and the hardness of the influent water can be removed when the influent water passes through the lower sodium type positive resin. When the effect is lost, the regenerated waste liquid of the ion exchanging salt removing system can be used for regeneration.
Description
The utility model belongs to water-treatment technology field.
Chlorine one sodium ion exchange process in the water treatment, be that water is continued by chlorine type anionite-exchange resin and sodium type Zeo-karb, thereby reach the purpose that reduces basicity in the water and remove hardness (148 pages of " boiler water processing " of publishing in 1989 referring to Hubei science tech publishing house).Usually, the yin, yang resin is to be placed in two interchangers, the back of losing efficacy with sodium chloride solution to two kinds of resins series connection regeneration.The ion exchange reaction of its system water and regenerative process as shown in the formula:
Negative resin: 2RCl+2HCO
- 3, SO
2- 4(system water)/(regeneration)
+ 2CL
-(1)
The ion-exchange demineralization water treatment system generally adopts HCl and NaOH to make the regenerator of sun bed and cloudy bed respectively.Its sun bed regenerating spent acid contains a large amount of Cl
-, can be used as the regenerator of negative resin in above-mentioned (1) formula; Contain a large amount of Na in its cloudy bed regeneration waste lye
+, can be used as the agent of above-mentioned (2) formula middle-jiao yang, function of the spleen and stomach regeneration of resin.Be provided with ion-exchange salt removing system at the same time and fall under the situation of alkali melded system, as adopt above-mentioned desalting system regeneration waste liquid, can save a large amount of working costs undoubtedly, and save the sodium chloride solution preparation system as the regenerator that falls the alkali melded system.
The utility model designs for this purpose.
Its constructional feature of alkali softening agent (referring to accompanying drawing) of falling of spent solution regeneration is, in falling alkali softening agent cylindrical shell ［ 1 ］, the cation exchange resin layer ［ 11 ］ that anion exchange resin layer ［ 5 ］ and floor height are not less than 1.2m is housed, being roughly yin, yang resin separation surface place, is the middle discharge opeing and the water feed apparatus ［ 8 ］ of a female pipe tubular type.Should be not less than half of yin and yang resin total height to the spatial altitude between the top water inlet water-freeing arrangement in the negative resin aspect.
During system water, processed water is entered by top through valve ［ 6 ］ and falls the alkali softening agent, downwards successively through the yin, yang resin layer, finishes and falls the softening ion exchange process of alkali, is discharged by the bottom then, delivers to main water outlet pipe through valve ［ 16 ］ again.In service, stable as using alkalinity of water, also can make the part water yield directly enter positive resin layer through valve ［ 7 ］.In service at one-period, along with negative resin reduces slowly weakening of basicity ability, reduce the aperture of valve ［ 7 ］ gradually.
When water outlet was leaked hardness and after losing efficacy, can locate water inlet by middle discharge opeing and water feed apparatus ［ 8 ］, a backwash negative resin layer also can be through valve ［ 13 ］ by the whole resin layer of bottom water inlet backwash.Under a backwash negative resin layer situation, bottom sun resin layer is to be in the counter-current regeneration operating mode, so effluent quality is better, operating capacity is also higher.But after operation some cycles number (as the 10-20 cycle), must carry out once big reverse washing, to remove resin in small, broken bits and the long-pending dirt of filter in the positive resin layer to whole resin layer.Be to improve the backwash effect, also can be installed into pneumatic plant, so that clean at the big reverse washing line space gas that advances at place, positive resin layer bottom.
Regenerate after the backwash.The spent acid that makes regeneration desalting system sun bed enters and falls the alkali softening agent by advancing spent acid device ［ 4 ］ through valve ［ 15 ］, downwards co-current regeneration negative resin layer; The waste lye of the cloudy bed of regeneration desalting system is entered by the bottom through valve ［ 17 ］ fall the alkali softening agent, bottom-up counter-current regeneration sun resin layer.Upper and lower two strands of regeneration waste liquids are located to converge after valve ［ 10 ］ is discharged in middle discharge opeing and water feed apparatus ［ 8 ］.
In regeneration negative resin layer process, the HCO that part is displaced
- 3In acid waste liquid, will become H
2CO
3So, have a large amount of CO
2Gas is by separating out in the liquid.For regenerative process is normally carried out, need to get rid of CO by valve ［ 3 ］ continuously
2Gas simultaneously, notes regulating its aperture, in the control interchanger certain liquid level and pressure to be arranged.
In the positive resin layer process of regeneration, for preventing OH in the waste lye
-And CO
2- 3With regeneration product Mg

3Precipitation should avoid making the strong basicity waste lye directly to enter positive resin layer.
Above-mentioned desalting system regeneration waste liquid can be discharged at desalting system positive and negative bed and be fallen the synchronizing regeneration of alkali softening agent after pipeline is directly delivered to, and also can deliver to special exhausted bath box and store, when the need time spent is pumped to and falls the alkali softening agent.
The above-mentioned alkali softening agent principal feature of falling is:
1, utilize the desalting system regeneration waste liquid, the yin, yang resin in the alkali softening installation falls in regeneration, both can save the sodium chloride solution preparation system, can save a large amount of salt again, thereby reduces investment and working cost greatly.
2, anion and cation exchange resin is placed in the same interchanger, can reduce the table of equipment number, thereby saves floor space and facility investment.
3, counter-current regeneration sun resin layer helps guaranteeing effluent quality and improves operating capacity.
4, negative resin can adopt the waste and old negative resin that desalting system should not continue to use, and does not influence result of use, thereby can reduce the resin expense.
In the accompanying drawing: 1 is the interchanger cylindrical shell, 2 are the water inlet water-freeing arrangement, 3 is vent valve, 4 for advancing the spent acid device, 5 is the negative resin layer, and 6 is water intaking valve, and 7 is the negative resin backwash valve, 8 is discharge opeing and water feed apparatus in the middle of the female pipe tubular type, 9 are the backwash water discharge valve, and 10 is middle tapping valve, and 11 is positive resin layer, 12 for bottom water outlet water inlet and advance waste lye device (as water cap porous plate or quartz sand thickness etc.), 13 is the bottom backwash valve, and 14 is the bottom discharge valve, and 15 for advancing the spent acid valve, 16 is outlet valve, and 17 for advancing the salkali waste valve.
