Abstract
The invention provides a method for treating water for beer brewing. The method comprises the steps of treating water by mixing weak-acid cation exchange resin and strong-base anion exchange resin, then regenerating the resin by using a carbon dioxide saturated aqueous solution, recycling a regenerant, and recycling the regenerant for 50 minutes to treat the water. The method has the advantages of simple process, large water treatment amount and low production cost.
Description
The present invention relates to a kind of treatment process of tap water, is a kind of method with ion exchange treatment brewage water specifically.
Brewage is general adopts softer water, but an amount of yin, yang ionic exists taste, characteristic for beer in the brewing water, for the whole brewing process of beer and for improving quality of beer great effect is arranged.Usually lime method or ion-exchange membrane electrodialysis method are often adopted in the processing of brewage water.Lime method often because the lime adding is excessive, makes and contains remaining calcium hydroxide in the water, thereby have a strong impact on the saccharification in the brewage process.With ion-exchange membrane electrodialysis method treating water, then power consumption, water loss are big, and the utilization ratio of water generally only is 40～60%, and the effluent quality instability is unreasonable.A kind of method with the phreatic improvement water quality of ion exchange treatment is disclosed in the U.S. Pat 4448693.This method is a kind of ion exchange process of partial deionization, utilizes the weak acid resin be free acid type and is the mixed bed that the anionite-exchange resin of hydrocarbonate type is formed, and dissolved salt is replaced by carbonic acid, the atmospheric carbon dioxide removal that can outgas from carbonic acid:
Regeneration of ion-exchange resin, then opposite with above-mentioned product water reaction, CO
2Be dissolved under pressure in the undressed former water and generate carbonic acid, the two kinds of resins of can regenerating simultaneously.Carbonic acid is a kind of free of contamination chemical substance, so this method can not brought impurity such as Cl because of regeneration of resin
-, Na
+Deng, guaranteed water quality.But this method has adopted the long recovery time in regenerative process, after each regeneration, ion exchange resin regeneration must be more complete.But because in each regenerative process, along with regenerated continues, the ionic concn that is eluted will reduce gradually, regeneration efficiency is along with the prolongation of recovery time has also just reduced.Therefore, this method recovery time is long, and it is low to handle the water yield.
The object of the invention is to provide a kind of recovery time short, the method for the processing brewage water that aquifer yield is big.
The present invention adopts not too high tap water of total hardness and temporary hardness or underground water, uses weakly acidic cation-exchange resin and strongly basic anion exchange resin to former water section desalination, makes regenerator with the carbonic acid gas saturated solution then exchange resin is regenerated.Characteristics of the present invention are imperfections of having utilized regenerative process, have selected the suitable recovery time, have so both improved regeneration efficiency, and the water quality after guaranteeing again to handle meets the requirement of brewage.The present invention selects only 50 minutes recovery time for use, and regenerator recycles, and its advantage is the regeneration efficiency height, and the ion exchange resin after the regeneration is just penetrated behind the former water of handling 32 bed volumes.The total efficiency for the treatment of water of the present invention improves 30%.Recycling of regenerator can make itself and the carbonic acid gas that replenishes reach capacity very soon, even reaches hypersaturated state.
Fig. 1 is the schema that the present invention handles the brewage water.
Former water is from top to bottom by ion exchange column 1, and the total hardness of water to be flowed out reaches 7 Germany when spending, and just stops into water. Then regenerative agent-carbon dioxide saturated aqueous solution is passed through ion exchange column 1 from bottom to top, the regenerative agent that is come out by pillar 1 turns back to gas-liquid mixed tank 2, fully mix with carbon dioxide by spray equipment, make it saturated and be recycled to pillar 1 to use, after the regenerative agent continuous circulation uses 50 minutes, ion exchange resin regeneration is complete, and ion exchange column can be processed former water again. When hardness surpasses the desired hardness of brewing in the water of this ion exchange column after processed, just stop into water.
The ratio of weak-acid cation-exchange resin of the present invention and strong-base anion-exchange resin is 10: 1～1: the 1(volume ratio).
Embodiment:
With pack into a high 1300mm and internal diameter of 7 liters of D113 type weakly acidic cation-exchange resins and 7 liter of 201 * 7 strong alkaline quaternary ammonium I type anionite-exchange resin is the pillar of 170mm, be total hardness 13 German degree then, temporary hardness is that the former water of 9 German degree is crossed this ion exchange column in the footpath from top to bottom, flow velocity is 5～10 meters/hour, when going out water hardness is 7 Germany when spending, and just stops into water.Use the regenerator of the saturated arbon dioxide solution of 56 liters (4 bed volumes) then, with recycle pump control its flow be 25 bed volumes/hour, the pillar of from ion exchange column, regenerating from bottom to top, turn back to mixing tank by the regenerator that comes out in the post, by spray equipment spray and carbon dioxide thorough mixing, the carbon dioxide dividing potential drop is 4 crust.Be recycled to pillar by saturated aqueous solution regenerator, circulation repeatedly in this wise, after 50 minutes, regeneration finishes, and exchange column can be handled the water of 32 bed volumes.The total hardness of handling back water is 4.8～6.8 German degree, and temporary hardness is 3.5～4.6 German degree.The utilization ratio of water improves more than 80% than electroosmose process, and the treatment capacity of water improves 30%.
As seen from above-mentioned, the present invention not only technological process simplifies, and has increased the processing water yield greatly.
Method of the present invention not only can be applied to handle the brewage water, and can be used for handling the Other Drinks water.
