Description
Technical field
The utility model relates to stevioside and extracts equipment, is specially a kind of Steviosides production unit that utilizes membrane separation technique to come recovered acid, alkali wasteliquid.
Background technology
Steviosides claims steviol glycoside again, is commonly called as stevioside, is a kind of a kind of pure natural that extracts from the blade of catananche's sweet Stevia, high sugariness, low-calorie foodstuff additive.Be the 3rd class sugar source after sucrose, beet sugar, its sugariness is 200-300 a times of sucrose, but heat only is 1/300 of a sucrose.Steviosides acid and alkali-resistance, Heat stability is good, no fermentable can be preserved in the solution of PH3-9 for a long time, also do not decompose under the environment up to 200 degree, can be widely used in the sugared fields of nearly all usefulness such as food, beverage, wine brewing, medicine.
At present, adopt exchange resin method to extract to produce Steviosides, master operation for pulverize, extract, flocculation, filter, decolouring, absorption, refining, Sterile Filtration, spraying drying and metering packing etc., obtain the finished product Steviosides, its content (purity) is 90%.
The subject matter that resin method is produced Steviosides is that raw and auxiliary material (water, acid, alkali, formaldehyde) waits and consumes greatlyyer, causes production cost high, resins exchange operation particularly, a large amount of auxiliary material (hydrochloric acid and liquid caustic soda) of consumption in the resin regeneration process.After these auxiliary material solution use through corresponding production process, still have certain recycling and be worth; But all discharge at present with the form of waste water, or the neutralization reaction salify, or needing to throw in certain soda acid or other materials carry out neutralizing treatment.Thus, not only cause the discharging of a large amount of auxiliary material (water, acid, alkali) waste and waste water, simultaneously, sewage disposal difficulty and sewage load have been increased greatly because formaldehyde, acid, alkali are extremely strong to the biological activity destructive force of facultative anaerobe in the anaerobism tower (pond) in the treatment tank and obligatory anaerobic bacteria.
The utility model content
The technical problem that the utility model solved be to provide a kind of can recovered acid, the Steviosides production unit of alkali wasteliquid, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of can recovered acid, the Steviosides production unit of alkali wasteliquid, comprise nanofiltration membrane system, constant voltage storage tank and water pump.Wherein, the constant voltage storage tank comprises coarse filtration storage tank, relay tank and finished product storage tank, and the nanofiltration membrane system comprises one-level nanofiltration membrane and secondary nanofiltration membrane, and water pump comprises dehvery pump and high-pressure pump, is installed in respectively on the carrier pipe between each constant voltage storage tank and the nanofiltration membrane.On carrier pipe, also be provided with strainer.
The principle that described equipment adopts membrane separation technique realizes the high efficiente callback of acid, alkali wasteliquid.The principle of membrane separation technique is: because film has the selection perviousness, membrane separation process utilizes macromolecule membrane, is impellent with outside energy or chemical potential difference, to two-pack or multi-component solute separate with solvent, the technology of classification, purification and enrichment.
Beneficial effect: the utility model technology is simple, easy to use, the effect that reclaims waste liquid (acid, alkali) solution is comparatively obvious, not only can carry out auxiliary material (water, acid, alkali) recycles, reduce the direct discharging of waste water amount, reduce the wastewater treatment difficulty greatly, save production cost, also can reach the purpose of producing waste " minimizing, resource utilization, utilization again ", realize cleaner production, have advantages such as design is reasonable, reduction of discharging consumption reduction effect is obvious, social benefit and environmental benefit are all fairly obvious.
