Embodiment
The total design of the present invention is the filtration of soya products processing waste water by medical stone, gac and volcanic ash, quartz sand, obtains contained dry-matter in the clean water that can reuse and the waste water.The below introduces two embodiment around this design.
The first embodiment: a kind of hay tank 1 as shown in Figure 1, tank body is high more than 3 meters, and internal diameter is more than 1 meter, and the upper end is provided with water-in 2, and the lower end is provided with water outlet 7, is provided with three filtering layers 3 in the tank.Following 1/5 place, upper end is provided with Medical stone filtering layer 4 in the tank, and following 2/5 place, upper end is provided with activated carbon filter layer 5 in the tank, is provided with the quartzy sand hybrid filtering of volcanic ash layer 6 at the bottom of the tank.In conjunction with Fig. 2 Fig. 3 as seen, all there are framework 9 and wire netting 10 and a plurality of cotton yarn layer 11 in each filtering layer 3 both sides, and granule filter material is included in the inside.Wire netting 10 preferably adopts the copper gauze that is difficult for corrosion.The medical stone particle diameter 0.5-2mm of Medical stone filtering layer, thickness is between the 100-500mm.Activated carbon filter layer 5 in-built 100-120 purpose activity charcoal powders, thickness is 100-500mm.The volcanic ash particle diameter 0.5-2mm of the quartzy sand hybrid filtering of volcanic ash layer 6, quartz sand particle size 0.2-0.5mm, volcanic ash: quartz sand=1: 1.5-2, filtering layer thickness are 100-500mm.The external diameter of each filtering layer 3 and tank body internal diameter match, and the below is supported by the fixed block 8 on the tank skin, thereby all is demountable parts.
The use-pattern of this hay tank 1 is joined the water-in 2 of hay tank 1 and the water port of soyabean processing equipment 13 as shown in Figure 4, and water outlet 7 and the water purifying tank 14 of hay tank 1 join.Water purifying tank 14 communicates by the feed-water end of water pipe with soyabean processing equipment 13, can consist of a closed loop.During work, the waste water that soya-bean products processing equipment is discharged enters hay tank 1, by Medical stone filtering layer 4, the medical stone granule: here is a kind of to biological nontoxic, harmless and have certain bioactive complex ore, has stronger adsorption, formed aperture is about below 200 microns between the medical stone granule:, can adsorb pigment and salt in the waste water.The waste water that filters is during by activated carbon filter layer 5, and the effect of charcoal absorption yellow seriflux pigment is stronger, but the effect of absorption salt is less than medical stone, and the two has the effect that complements each other, and can reach the effect of decolouring desalination.Then enter the quartzy sand hybrid filtering of volcanic ash layer 6, quartz sand has good porosity, and the volcanic ash particle surface is with positive charge, and is anticorrosive, has inertia, do not participate in reaction in environment, do not affect the character of medium.In actual production, by simulated experiment and detection, adjust the parameters such as filtering layer grain diameter, filtering layer thickness, can reach or near the level of membrane filtration, can hold back the materials such as albumen in the waste water, stachyose, raffinose, sucrose, wood sugar, glucose, fructose.
Above-mentioned hay tank should be equipped with more than three, uses in turn, respectively cleaning.Stay filtering layer 3 the insides and top material for the ease of obtaining, hay tank 1 can be made the as shown in the figure tank body of multistage docking, and the timing fractionation can be taken off filtering layer 3 and be cleared up.Can take out the filtrate of filtering layer respectively during cleaning and clean, contained material mainly is pigment and impurity in the first layer, the second layer filtrate, most of functional substance three-layer filter and above the space in, again by repeating the series of processes such as desalination, protein isolate, spraying drying, can obtain albumen and carbohydrate to the crude product of gained.Filtrate can reuse after cleaning, and cost is extremely low.Filtered water detects and reaches reusable standard, can reuse.Resulting dry-matter can be used as nutritious prod and healthcare products raw material, sells to specialized factory and processes separately by sub-electing.
Since 2010, carried out many experiments, the below only exemplifies two parts of experimental datas:
Leaching amount (unit: mg/L) in the yellow seriflux during table 1, bean product are produced
| Soybean isoflavones | Solids | Crude protein | Total reducing sugar | Soyasaponin | Phytic acid |
| 67 | 16500 | 3900 | 10800 | 132 | 17 |
The leaching amount of whey-protein and sugar in table 2, the dregs of beans processing waste water
The second embodiment: as shown in Figure 5, be provided with a branched pipette 15 above each filtering layer 3 of hay tank 1, valve and sucking pump are housed above the suction pipe 15, can start at any time and outwards collect the material that filtering layer 3 is piled up above, can also close water-in 2, make the water pump counter-rotating of water outlet 7, inwardly squeeze into water purification, discharge by suction pipe 15 again, can clean respectively each filtering layer 3, like this, need not split tank body and just can clear up, operate very simple.
