Abstract
A regenerating agent of sodium and ammonium ion resin is prepared from sodium chloride (4-6 wt.portions), sodium sulfate (1-3), ammonium chloride (1-4), complexing agent (0-0.2) and surfactant (0-0.2) and can be used for water processing to obtain soft water. Its advantages include less consumption of edible salt saved by 5-10%, low cost reduced by 10%, high quality of soft water, long service life of resin and low chlorine content in discharged water (reduced by 25%).
Description
The present invention relates to a kind of regenerative agent, the especially a kind of strongly acidic styrene's series cationic ion-exchange resin of soft water processing and regenerative agent of sulfonated coal of being exclusively used in.
The Chinese invention patent application discloses a kind of compound regenerator used in hard water softener No. 93120933.1, the Main Ingredients and Appearance of this regenerative agent is a sodium chloride, utilize the calcium, the magnesium ion that adsorb on the resin in sodium ion in the sodium chloride and the demineralizer to exchange, make ion exchange resin obtain regeneration.But above-mentioned existing regenerative agent salt consumption is bigger, and cost of use is higher.Simultaneously, in the resin regeneration processing procedure, chloride ion content is too high in institute's waste discharge, is unfavorable for environmental protection.Therefore, above-mentioned existing regenerative agent exists defective.
The purpose of this invention is to provide that a kind of salt consumption is less, usage charges are lower, help sodium, the ammonium ion resin regeneration agent of environmental protection.
Sodium of the present invention, ammonium ion resin regeneration agent are made of the raw material of following weight portion: 4～6 parts in sodium chloride, 1～3 part in sodium sulphate, 1～4 part of ammonium chloride, 0～0.2 part of chelating agent, 0～0.2 part in surfactant.When using regenerative agent of the present invention that soft water process resin and sulfonated coal are regenerated, following reaction can take place:
………………①
………………②
………………③
………………④
………………⑤
………………⑥
With regard to above-mentioned course of reaction, equation 1., 2. given course of reaction is identical with course of reaction when only adopting sodium chloride as regenerative agent.But owing to have ammonium chloride in the regenerative agent, the reaction of itself and calcium, magnesium ion by reaction equation 3., 4. provide; Also has sodium sulphate in the regenerative agent, the reaction of itself and calcium, magnesium ion by reaction equation 5., 6. given, can allow the calcium in the actified solution, the concentration of magnesium ion reduce thus, thereby impel reaction equation 1., 2., 3., 4. given course of reaction is to equational right-hand carrying out, and prevents anti-ionization effectively.Simultaneously,, compare during with whole employing sodium chloride, use the chloride ion content in the regenerative agent time institute waste discharge can reduce about 20%, correspondingly reduced the pollution of chlorion, help water quality protection environment because sodium sulphate occupies certain proportion in the regenerative agent.Require emphasis and be pointed out that: in theory, only adopting sodium sulphate also is feasible as regenerating agent of Na-ion resin.But result of the test shows that when only adopting sodium sulphate, for resin being implemented regeneration effectively, the sodium sulfate concentration in the regenerant solution usually can be greater than 3%.In case and the sodium sulfate concentration in the regenerant solution surpasses 3%, tangible graininess precipitation will in the resin regeneration process, occur, and this graininess precipitation can be stopped up the resin mesh, causes resin to be scrapped.In addition, only adopting ammonium chloride also is infeasible as regenerating agent of Na-ion resin, and it can make boiler alkalinity descend, and influences the operate as normal of boiler.Therefore, can not adopt sodium sulphate or ammonium chloride as regenerating agent of Na-ion resin separately.And in the present invention, adopt sodium chloride, sodium sulphate and ammonium chloride to be configured to regenerative agent, when resin being regenerated processing, the sodium sulfate concentration in the regenerant solution can be controlled in below 2% usually.Result of the test shows that the regenerative agent of the present invention under this state can be implemented regeneration to resin effectively and handle, and can not produce graininess precipitation (solution that detects by an unaided eye does not have turbid phenomenon) again in solution, thereby can guarantee that the resin mesh can be not blocked.So, adopt sodium chloride, sodium sulphate and ammonium chloride to be configured to regenerative agent among the present invention simultaneously, can eliminate the disadvantage that is had when the three uses separately effectively.In the present invention, chelating agent and surfactant add as auxiliary composition.That is to say that adding chelating agent and surfactant is not the essential condition of producing regenerative agent of the present invention.Generally, in regenerative agent, add chelating agent and help stoping the pollution to resin such as iron ion, aluminium ion, prolong the service life of resin, improve the resin operating capacity, improve iron, aluminum ions eluting rate.The adding surfactant then can change the electric field in the ion exchange process in regenerative agent, impels the rapid migration of counter ion, realizes effective control of film diffusion velocity and particle diffusion velocity, and then improves regeneration level and reduce the salt consumption.In the present invention, chelating agent that is added and surfactant can be commercially available mill run.For example, chelating agent can adopt sodium pyrophosphate or calgon etc.; Surfactant can adopt sodium phosphate trimer or neopelex etc.
Practical application shows: compare with the existing product of aforementioned simple employing sodium chloride, regenerative agent of the present invention can reduce salt consumption 5～10%, save regeneration expense about 10%, help improving the soft water treating capacity, prolong regeneration of resin cycle and service life, make chlorinity reduction about 25% in the discharge of wastewater, reduce pollution water quality.
