Description
Technical field
The present invention relates to a kind of regenerator, the especially a kind of strongly acidic styrene's series Zeo-karb of soft water processing and regenerator of sulphonated coal of being exclusively used in.
Background technology
Strongly acidic styrene's series Zeo-karb and sulphonated coal are widely used in the soft water processing.After using for some time, need handle above-mentioned exchange resin and sulphonated coal with regenerating agent of Na-ion resin, promptly utilize the calcium, the magnesium ion that adsorb on sodium ion and the ion exchange resin in the regenerator to exchange, make ion exchange resin obtain regenerating.At present the sodium ion soft water processing resin regenerating agent that uses is common in sodium-chlor (salt) or based on the mixture of sodium-chlor, as No. 93120933.1 disclosed compound regenerator used in hard water softener of Chinese invention patent application, the major ingredient of this regenerator is a sodium-chlor; And for example the applicant is at No. 01107093.5 disclosed regenerating agent of Na-ion resin of Chinese invention patent application, and this regenerator is made of the raw material of following weight part: 4～6 parts in sodium-chlor, 4～6 parts in sodium sulfate, 0～0.2 part of chelating agent, 0～0.2 part in tensio-active agent; The applicant is in No. 01107319.5 disclosed sodium of Chinese invention patent application, ammonium ion resin regeneration agent for another example, and this regenerator is made of the raw material of following weight part: 4～6 parts in sodium-chlor, 1～3 part in sodium sulfate, 1～4 part of ammonium chloride, 0～0.2 part of chelating agent, 0～0.2 part in tensio-active agent.Above-mentioned existing regenerating agent of Na-ion resin finished product is Powdered.Theoretical and the experiment according to resin regeneration, usually should use the regenerator aqueous solution (or claiming regenerated liquid) that above-mentioned ion exchange resin was handled about 40 minutes continuously, in treating processes,, then will obtain best manipulation of regeneration effect if make the regenerator concentration of the regenerator aqueous solution maintain 5～8%.When manipulation of regeneration, method commonly used now is that first resin regeneration agent with some amount places the molten device of salt, allow clean water constantly flow through the molten device of salt in a steady stream again and arrive ion exchange resin column, in clean water is flowed through the process of the molten device of salt, clean water will make partial regeneration agent dissolving, flow out the molten device of salt and the water that arrives ion exchange resin column in fact that is become the regenerator aqueous solution.But, because above-mentioned existing regenerating agent of Na-ion resin is Powdered, practice shows, this pulverous regenerator can dissolve in 10～15 minutes after introducing clean water fully, at its dissolving initial stage, flow out regenerator concentration in the aqueous solution of the molten device of salt up to more than 20%, regenerator concentration then levels off to zero after 15 minutes.Therefore, in above-mentioned regeneration process, adopt existing Powdered regenerating agent of Na-ion resin not only can waste regenerator, strengthen regenerant consumption, and can not carry out manipulation of regeneration to resin preferably, its regeneration effect is also relatively poor.In order to address this problem, the measure of taking now is earlier Powdered regenerator to be inserted the salt bath, in the salt bath, add water make it the dissolving and dissolve into desired concn (5～8%) after, with pump solution is delivered to ion exchange resin column again, resin is carried out manipulation of regeneration.This method is actually a kind of technologic falling back, it not only needs to increase corresponding handling equipment and maintenance cost, and adopt artificial local method to operate fully, to all artificially control such as the flow velocity of the regenerator aqueous solution, flow, regeneration quality instability, the full-automation of the water-softening plant that more is unfavorable for realizing regenerating.Therefore,, promote the full-automation of regeneration water-softening plant, be necessary sodium ion soft water processing resin regenerating agent is improved in order to obtain preferably regeneration effect and to reduce regenerant consumption.
Summary of the invention
The purpose of this invention is to provide a kind ofly reduce regenerant consumption, favorable regeneration effect, the sodium ion soft water processing resin regenerating agent of the water-softening plant full-automation that helps regenerating.
Resin regeneration agent of the present invention is a kind of formed sodium ion soft water processing resin regenerating agent, this regenerator is made in the following manner: Powdered sodium ion soft water processing resin regenerating agent is sent in the press-forming machine, under 30～100 tons pressure, it is pressed into the plates of 2～16 square centimeters of thick 0.2～2 centimetres, surface-area, gets product.In the present invention, said Powdered sodium ion soft water processing resin regenerating agent can directly adopt sodium-chlor (salt) or the applicant at No. 01107093.5, foregoing invention patent application, No. 01107319.5 disclosed sodium ion soft water processing resin regenerating agent of application for a patent for invention.Said press-forming machine can be existing relative rolling type press-forming machine or fluid pressure type shaper etc.According to the Powdered regenerator raw material composition that is adopted and the condition of manipulation of regeneration, can in above-mentioned given pressure range and thickness range, select the thickness of pressing pressure and final finished product.The finished product that obtains after the compacting can be the plates of regular shape, as disc, but also can be the plates of non-regular shape.The present invention recommends plates are pressed into the plates of the non-regular shape of 2～16 square centimeters of thick 0.2～0.5 centimetres, surface-area, in addition, also plates can be pressed into the disc plates of 0.5～3 centimetre of thick 0.5～2 centimetre, diameter.
Compare with aforementioned existing Powdered regenerator, the density of moulding regenerator of the present invention increases, and the soluble surface area in water (i.e. the surface-area that contacts with water) reduces, and its dissolution rate obviously slows down, thereby can prolong the regeneration of resin treatment time.Simultaneously, owing to the soluble surface area of plates can not have greatly changed along with the continuity of dissolution time (when plates are thin, especially true when surface-area is big), therefore can make the meltage of day part roughly the same, the corresponding solution that makes remains certain concentration.Like this, when moulding regenerator of the present invention being inserted the molten device of salt when being used for resin regeneration, just can allow the concentration of the regenerator aqueous solution that flows out the molten device of salt match with theoretical dissolution concentration (the regenerator concentration of aqueous solution maintains 5～8%), simultaneously, its complete dissolution time also can be consistent with the optimum handling time (continuously handle about 40 minute) of regenerator to ion exchange resin.So moulding regenerator of the present invention has favorable regeneration effect, the advantage of the water-softening plant full-automation that helps regenerating.Simultaneously, because the concentration of ordinary dissolution of moulding regenerator and complete dissolution time can satisfy the requirement of best regenerative process, avoided using Powdered regenerator the molten device of salt or automatically in the sodium ionomer resin interchanger dissolution rate too fast and cause the situation that regenerated liquid concentration is higher, regenerating agent consumption increases, can not cause the waste of regenerator.Practical application shows: if use molten device of salt or automatic sodium ionomer resin interchanger to do resin regeneration, compare with Powdered regenerator, use moulding regenerator of the present invention can reduce regenerant consumption about 20%, save regeneration expense about 30%, economic and social benefit is very remarkable.In addition,, also help the soft water treatment capacity that improves resin, prolong its regeneration period because regeneration effect is better.
Content of the present invention further illustrates with the following Examples, but content of the present invention is not limited only to content related among the embodiment.
