Description
Technical Field
The invention relates to the field of sugar production, in particular to a regeneration method of ion exchange resin in a sugar production process.
Background
Sugar is the most important carbohydrate source for human beings, the commonly used sugar-making raw materials are sugar cane and sugar beet, the commonly used production process is squeezing sugar cane or boiling sugar beet in water to obtain sugar juice, filtering to remove impurities, adding a proper amount of lime water into the filtrate, filtering again to remove precipitates, introducing carbon dioxide into the filtrate to precipitate the lime water into calcium carbonate, and filtering again to obtain the filtrate which is the aqueous solution of sugar, wherein the concentration is generally 10-20%. The sugar solution is put into a vacuum container for reduced pressure evaporation, concentration and cooling, reddish brown slightly sticky crystals are separated out, and the sugar is the sugar, and sticky molasses which cannot be crystallized is obtained. Because sugar cane and beet are crops, the obtained sugar juice contains a lot of salt, and lime is used for processing the sugar juice in the sugar making process, so that the calcium content of the sugar juice is very high, and a large amount of calcium-containing compound precipitates, namely the scale formation which is often called in the subsequent evaporation and concentration stages can be generated. After the equipment is scaled, the heat exchange efficiency of the equipment can be influenced, and the heat energy consumption is increased. In order to solve this problem, sugar factories generally perform decalcification treatment, that is, removal of most of calcium ions from sugar solutions by using ion exchange resins, before concentrating the sugar solutions.
The prior art has the defects that: after the ion exchange resin is saturated, the resin needs to be regenerated, namely, calcium ions absorbed by the resin are removed, and the conventional regeneration methods all use NaOH and NaCL, so that the regeneration liquid is high in cost, and a large amount of waste water is generated.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a method for regenerating ion exchange resin in a sugar manufacturing process.
In order to achieve the purpose, the invention designs a method for regenerating ion exchange resin in a sugar manufacturing process, which comprises the following steps:
1) after the sugar juice is decalcified by ion exchange resin, the sugar juice enters common concentration and sugar boiling processes to obtain sugar and molasses, wherein the molasses contains about 60 percent of sugar and a large amount of salt;
2) filtering and separating the molasses by chromatography to obtain sugar and non-sugar components; wherein the non-sugar component comprises pigments, organic macromolecules and salts (including a plurality of K, Na ions);
3) the non-sugar component is used as a regenerant for regenerating the ion exchange resin softened by the decalcification treatment.
Further, in the step 1), the ion exchange resin is a sodium type ion exchange resin or a potassium type ion exchange resin.
The principle of the invention is as follows:
1. firstly, softening sugar juice extracted in the sugar making process by sodium type (potassium type) ion exchange resin, namely replacing calcium ions with sodium ions and potassium ions; the reaction formula is as follows:
2(R-SO3Na)+→Ca2+2(R-SO3)2Ca2++2Na+
r represents the structure of the resin, which can be other monovalent ions, such as potassium ions;
2. the chromatographic separation process utilizes different distribution coefficients of different substances in a system consisting of a stationary phase and a mobile phase, and when the two phases move relatively, the substances move along with the mobile phase and are repeatedly distributed between the two phases, so that the substances are separated. The stationary phase of the separation process is strong acid cation exchange resin. The mobile phase is pure water.
The molasses is subjected to chromatographic separation. To obtain sugar component and non-sugar component. The non-sugar components comprise all pigments, organic macromolecules and salts in the sugar solution; and the salt content contains a large amount of K, Na ions.
The above-mentioned non-sugar component is used as a regenerant for the above-mentioned softening resin to regenerate the softening resin and restore the adsorption function of the resin.
2(R-SO3)2Ca2++→2Na+(R-SO3Na)+Ca2+。
The invention has the beneficial effects that:
the invention uses the sucrose produced by sugar production, and the resin is regenerated after treatment, thereby avoiding the use of other regenerants, reducing the cost and reducing the production of pollutants.
