Description
Technical field
The utility model relates to a kind of dealcoholysis system that is used to prepare colourless or light-coloured transparent alkyl glycoside.
Technical background
Alkyl glycoside (also claiming APG), APG for short is a kind of green nonionogenic tenside.At present production alkyl glycoside technology has the glucosides of commentaries on classics method (claim not only two-step approach) and direct glucosides method (but also claiming single stage method), two-step approach be by low-carbon alcohol earlier with the sugar reaction, generate low carbon glycoside after, carry out conversion reaction with long carbochain alcohol again, generation alkyl glycoside crude product.Single stage method is directly to generate thick alkyl glycoside with the sugar reaction by long carbochain alcohol.No matter be two-step approach or single stage method, all adopt the Fatty Alcohol(C12-C14 and C12-C18) excessive response, the thick alkyl glycoside of production all contains excess fats alcohol, all needs to carry out dealcoholysis.Yet expect light color or colourless alkyl glycoside, reaction of guanosine, dealcoholysis, bleaching process all are key factors, and the dealcoholysis influence factor is bigger, because of dealcoholysis temperature in the whole production process the highest, in the dealcoholysis system, temperature, vacuum tightness and residence time of material length are having a strong impact on product colour, so adopt suitable dealcoholysis system and how to reduce residence time of material and gas clean-up, the focus that has just become people to pay close attention to.
Existing two-step approach alkyl glycoside production dealcoholysis system, be in the dealcoholysis still of continuously stirring, to carry out, material is oversize in the certain temperature and the following residence time of vacuum, glucosides is gelatinization very easily, so the alkyl glycoside color of producing is darker, be exactly that color is also unsatisfactory, so be eliminated gradually after adopting the reinforcement bleaching.
The dealcoholysis system of existing single stage method alkyl glycoside, the employing falling-film evaporator that has series connection scrapper thin film evaporator is added discharging pump and discharging check valve, goes the technology of aftertreatment again; Employing falling-film evaporator series connection scrapper thin film evaporator two covers that have divide a secondary dealcoholysis, and adopt many input and output material pumps, and system outlet adopts check valve technology; Also have and adopt two cover scrapper thin film evaporator series connection, export the technology that adds check valve for discharging pump.
Adopt the dealcoholysis system of abovementioned alkyl glucosides that following defective is arranged:
1. technical process is long, and device systems is big, and vacuum tightness is low, needs to be equipped with high-power high vacuum system, and facility investment is big, the cost height.
2. material at high temperature the residence time longer, the easy gelatinization of product, coking, product colour is dark.
3. owing to adopt many discharging pumps and check valve, system is easily stopped up, and is difficult to guarantee continuous production.
4. input and output material pump coupling is strict, restive.
The utility model content
Technical problem to be solved in the utility model provides a kind of continuous smoothness that can guarantee production, guarantees the shortest residence time of material, can realize producing the dealcoholysis system of colorless transparent alkyl polyglucoside.
The utility model adopts following technical scheme:
The utility model comprises thick glycosides jar, feeding pump, scrapper thin film evaporator, receiving tank, dissolving bleaching still, oily temperature controller, vacuum unit, nitrogen basin, described thick glycosides jar is connected with the upper end of scrapper thin film evaporator by feeding pump, the lower end discharge port of scrapper thin film evaporator is connected with the upper end opening for feed of two receiving tank respectively, two receiving tank are connected with nitrogen basin, vacuum unit respectively, the lower end discharge port of receiving tank is connected with the opening for feed of dissolving bleaching still, and described dissolving bleaching still lower end is provided with discharge port.
The beneficial effects of the utility model are:
Because material system of the present utility model all with deep fat companion heat, zero discharge pump, no check valve, no falling-film evaporator, only adopts a scraper evaporator, two receiving tank, two dissolving bleaching stills.The full-bodied alkyl glycoside of scrapper thin film evaporator input is directly exported to receiving tank after by dealcoholysis, goes dissolving to float dissolving of look still and decolouring again.Total system is vertically installed, can guarantee to produce continuous smoothness, thereby avoided that original technological system is big, long flow path, easily stop up, easily gelatinization, easily coking, vacuum tightness is low, dealcoholysis is incomplete and be difficult to operation, production can not reach saturate numbness disease continuously, improved production efficiency and saved relevant manpower and materials.
Adopt the utility model dealcoholysis system, vacuum tightness height, residence time of material are short, discharging is fast, not gelatinization of product, technology are simple, easy to operate, alkyl glycoside clear transparent after the dealcoholysis, of light color, float look well, after bleaching, can obtain water white alkyl glycoside.
