Abstract
The present invention relates to ion exchange resin regeneration liquid of sugar liquor decoloration, which is composed of calcium oxide, calcium chloride and sugar, or calcium chloride and sugar, or aluminum hydroxide and sugar. In the regeneration method, eluant through regeneration treatment under certain conditions is carbonated by CO2 or added with phosphoric acid so that calcium ions precipitate to generate calcium carbonate or calcium phosphate; after filtration, the eluant is repeatedly used, or the eluant directly returns to main flow paths without treatment. Because the eluant after the regeneration method mainly contains sugar and calcium salt which are recovered into the main flow path without generating pollution; in addition, the consumption of regeneration reagents and washing water is greatly reduced, and the environment is protected.
Description
The present invention relates to be used for the decolouring of carbohydrate goods industry liquid glucose, comprise the decolouring of sucrose, beet sugar, Dian Fentang, biological polyoses, functional oligose and various monose.
The refining material of spent ion exchange resin is a kind of effective ways of food and biochemical industrial application, though absorption impurity is simple operation, desorption has certain degree of difficulty, causes ion exchange technique to be restricted in industrial application.The main method that makes resin regeneration at present is chemical method-sodium-chlor or alkaline sodium chloride solution method of reproduction, though this method consumption simple to operate pharmaceutical chemicals is many, blowdown flow rate is big.Usually use the alkaline NaCl solution of 4-10% in the tradition sugar refining technology, not only can not effectively remove the pigment on the resins exchange base with this regenerator but also produce a large amount of waste liquids, so seriously polluted owing to contain in the alkaline NaCl elutriant that a large amount of coloring matters and sodium salt cause COD and BOD too high levels.
The objective of the invention is to shortcoming at the prior art existence, a kind of ion exchange resin regeneration liquid of liquid glucose decolouring is provided, can effectively removes the pigment on the resins exchange base, can be used for after the use in sugaring or the sugar refinery technical process, thereby consumption is few, and does not produce waste liquid and pollution.
The present invention also aims to provide a kind of ion exchange resin regeneration method of liquid glucose decolouring.
The ion exchange resin regeneration liquid of liquid glucose decolouring of the present invention is made up of calcium oxide, calcium chloride and sugar; Or calcium chloride and sugar composition; Or aluminium hydroxide and sugar composition.
The regenerated liquid consumption that calcium oxide and sugar are formed is a calcium oxide 1-50 grams per liter, sugared 20-600 grams per liter.Optimum amount is a calcium oxide 5-10 grams per liter, sugared 100-150 grams per liter.
The regenerated liquid consumption that calcium chloride and sugar are formed is chlorion (Cl
-) concentration 2-40mol/ liter, sugared 20-600 grams per liter.Optimum amount is chlorion (Cl
-) concentration 10-20mol/ liter, sugared 100-150 grams per liter.
The regenerated liquid consumption that aluminium hydroxide and sugar are formed is aluminum ion (Al
3-) concentration 0.002-0.05mol/ liter.Optimum amount is aluminum ion (Al
3+) concentration 0.008-0.01mol/ liter, sugared 100-150 grams per liter.
Above-mentioned regenerated liquid is the aqueous solution.
Raw materials used calcium oxide or the natural matters such as calcium chloride or aluminium hydroxide and sugar of comprising of above-mentioned regenerated liquid, work in-process and finished product, the restriction with kind of not originated.
The ion exchange resin regeneration method of liquid glucose decolouring of the present invention comprises
---liquid glucose enters from an end of ion exchange column, and the other end flows out, and decolours, and the liquid glucose in the decolouring back water backwash post when syrup concentration is reduced to and equates with sugar concentration in the regenerated liquid in the post, is regenerated;
---during regeneration, regenerated liquid is added from an end of ion exchange column, the other end flows out, with 1-3 times of resin bed volume/hour velocity flow cross resin column, temperature is controlled at 40-70 ℃, the regenerated liquid consumption be the resin bed volume 1-4 doubly.---the elutriant CO that comes out after the manipulation of regeneration
2Full charge or add phosphoric acid and make calcium ion precipitation generate lime carbonate or calcium phosphate is filtered the back and is reused.The perhaps not treated main flow of directly getting back to of elutriant.
The present invention compared with prior art has following advantage and effect:
1, the present invention with alkaline calcium salt or aluminium salt with liquid glucose as regenerated liquid, calcium salt and aluminium salt regenerator improve than traditional alkaline salt solution greatly to the pigment elutive power that anchors on the exchanger, its reason is Ca
2-Or Al
3-Existence increased substantially Cl in the pigment negatively charged ion of solid phase adsorption and the liquid phase
-Switching performance.
2, the elutriant after the manipulation of regeneration mainly contains sugar part and calcium salt, can be recovered in the main flow and does not produce pollution, and can significantly reduce regeneration reagent and washing water consumption, helps environment protection.
3, under the less salt state, the over-drastic pucker ﹠ bloat does not take place in ion exchange resin, can effectively prolong the work-ing life of resin.
4, this Ca (OH) that has
2Or Al (OH)
3Regenerated liquid can be used in and the secondary sugar of low-purity, also can calcium ion be removed by carbonation or the method that adds phosphoric acid precipitates, directly reclaim and be used as regenerated liquid.
