Background technology
Ascorbic production technique because the application of membrane separation technique is greatly improved, has all had bigger improvement at aspects such as product quality, yield and energy consumptions in recent years.
In the concentrated production process of the ancient dragon acid of wherein ascorbic midbody; Traditional method is with resin ion exchange liquid evaporation concentration, and is as shown in Figure 1, and the concentration of sodium colombate is generally 3-5% in the sodium colombate solution after the IX of process resin; The cost of investment of vaporizer is high; Energy consumption is high, and because sodium colombate under hot conditions, quality also is under some influence.In recent years; Use nf membrane that the resin ion exchange liquid is concentrated earlier, can the sodium colombate concentration in the liquid concentrator be increased to 10-12% from 3-5% after using traditional nf membrane concentration technology, get into vaporizer then and further concentrate; Cooperate shown in Figure 1; This application is because it saves equipment investment cost, cuts down the consumption of energy and improves the advantage of product quality, and the method for this nf membrane concentrated resin ion exchange liquid is widely used.
Traditional nf membrane thickening equipment is because the reason of equipment itself; The maximum working pressure of nf membrane is 40bar; Under the pressure condition that is not higher than 40bar, can't the concentration of sodium colombate further be improved, so; Tradition nf membrane concentration technology can steady running maximum concentration be 10-12%, the investment of evaporation equipment and energy consumption still remain high.
The utility model content
The purpose of the utility model is to provide the imperial sour high power of a kind of Gu to concentrate production unit, uses the method for membrane sepn that the imperial acid concentration of Gu is increased to higher concentration, reduce vaporizer cost of investment, cut down the consumption of energy and improve product quality.
In order to reach above-mentioned purpose, the solution of the utility model is:
The imperial sour high power of a kind of Gu concentrates production unit, comprises that dehvery pump, accurate filter, topping-up pump, online topping-up pump and high power concentrate film; The inlet of dehvery pump connects the inlet of feed liquid pipe, outlet connection accurate filter; The outlet of accurate filter connects the inlet of topping-up pump; The supercharging pump outlet connects the inlet of online topping-up pump; Online supercharging pump outlet connects the inlet that high power concentrates film, and the outlet that high power concentrates film comprises dialyzate pipeline and liquid concentrator pipeline, and the liquid concentrator pipeline forms two branches, and branch effluxes and another branch's backflow also is connected to the inlet of online topping-up pump.
Said accurate filter is 5 microns core formula or a pocket type accurate filter.
Said topping-up pump is a high pressure plunger pump.
Said high pressure plunger pump is the no oil piston pump of feed liquid self-lubricating or has lubricating oil that the rampump of leakage of oil sfgd. is still arranged; Material is stainless steel SS316 or SS316L material.
Said online topping-up pump is the impeller pump of hygiene-type inlet high pressure resistant (anti-60-70bar), and material is SS316 or SS316L.
It is organic materials nf membrane or reverse osmosis membrane that said high power concentrates film; Can be tubular type, rolling or plate armature; Molecular weight cut-off is 50-200Dalto (dalton), and proof pressure is 0-200bar.
After adopting such scheme, the utility model uses this equipment, at the pressure of 50-75bar, 10-40
oUnder the condition of C and pH=1-2, after the process high power concentrates, can the concentration of sodium colombate be increased to 20-24% from 3-12%, the rate of loss of sodium colombate is not higher than 1% in the dialyzate of generation, and the content of sodium colombate is not higher than 0.2% in the dialyzate.The utility model is equivalent on original basis, the concentration of sodium colombate is doubled, greatly investment of the reduction evaporation equipment of degree and energy consumption.
High pressure components of system as directed in the utility model adopts internal recycle; Be about to most high pressure liquid concentrator and be back to high voltage bearing online topping-up pump inlet; The low concentration solution that transports with topping-up pump mixes back entering filter membrane, and the energy consumption that total system is whenever deviate from one ton of water is no more than 10kwh, compares the steam that one ton of water of conventional evaporator evaporation needs the 0.3-0.4 ton; According to 0.6 yuan of every degree electricity; The expense that steam per ton is 200 tons uses the energy consumption cost of the utility model to be merely 10% of conventional evaporator method, and effects of energy conservation and environmental protection is very outstanding.
Because be higher than under 24% the concentration conditions, sodium colombate solution is easily at the film surface crystallization, and operation causes detrimentally affect to the industrial system continous-stable, so the utility model needs the sodium colombate concentration of the final liquid concentrator of strict control not to be higher than 24%.Because the concentration of sodium colombate and solution density have proportional relation, use online specific gravity hydrometer or on-line densimeter control liquid concentrator proportion between 1.090 to 1.108, corresponding sodium colombate strength of solution is 20% to 24%.
