A kind of clear juice buoyancy system

Technical field

The utility model belongs to sugar refining field, relates to a kind of clear juice buoyancy system.

Background technology

Clear juice (also the claiming air supporting) technology that floats is in recent years for one of the new technology of sugar industry technology, but most producer uses this technology to fail, less effective, so far, and the domestic also producer that uses of success.

Clear juice phosphorus floats the Introduction on Principle of technology: floating is this mechanism of sticking power utilized in tiny bubble and liquid glucose between suspended substance, namely in clear juice, air is passed into, and separate out from clear juice with micro-bubble form and become carrier, the nonsugar such as colloid, small suspended particle in juice is clearly made to stick on bubble, clear juice face is floated to bubble, foam----gas, syrup, particle (suspended substance) three-phase mixture, reach separating impurity by dregs scraper scumming or scum silica frost, purify the object of clear juice in formation.Find with microscopic examination, the bubble in impure liquid glucose has thicker bubble chamber film, and has attachment in various degree between calcium phosphate crystal.Actual and theory shows, in pure water and pure liquid glucose, the sticking power of bubble and calcium phosphate is very weak, but time impure, situation can change greatly.In liquid glucose, non-sugar impurities more greatly and more gathers (adsorbed or cover) on bubble surface because of surfactivity.On the other hand, also have and adsorb more by force between surfactant and calcium phosphate, calcium phosphate has stronger adsorptive power throw out, and it can adsorb colloid and other non-sugar, adsorpting pigment reduce colour, and can promote throwing out.Calcium phosphate is attached on bubble, and in liquid glucose, floating limit adsorbing contaminant is carried out on limit, reaches the object of removing impurity.Flocculated impurities in liquid glucose after fully floating to floating device top liquid level, then pushes away toward floating device edge through scraper plate, can form denseer scum silica frost, after skim, filtration, remove impurity.But Syrup Flotation technique because of syrup concentration comparatively large, viscosity is large, and poor fluidity, it is more that scum silica frost takes away sugar, and scum silica frost is difficult, and the flow process of getting back to mud juice bucket or mixed juice case is longer, and sugar loss is more.

Utility model content

The purpose of this utility model is to provide a kind of clear juice buoyancy system, and solve because syrup concentration is comparatively large in existing sugaring process, it is more that scum silica frost takes away sugar, causes the problem that sugar loss is more.

The technical scheme that the utility model adopts comprises phosphoric acid volume pump and clear juice case, phosphoric acid volume pump and clear juice case ligation case respectively, fogbroom is provided with in reaction box, reaction box connects hybrid reaction chamber, hydrolysis case connects flocculation agent volume pump, flocculation agent volume pump connects hybrid reaction chamber, and hybrid reaction chamber connects clear juice floating device by hybrid reaction pipeline, and clear juice floating device connects approximately cloth vacuum suction filter and accelerated clarifier respectively.

It is less that the beneficial effects of the utility model are that the scum silica frost in sugaring process takes away sugar, and sugar loss is few.

Accompanying drawing explanation

Fig. 1 is a kind of clear juice buoyancy system structural representation of the utility model.

In figure, 1. phosphoric acid volume pump, 2. clear juice case, 3. reaction box, 4. fogbroom, 5. hybrid reaction chamber, be 6. hydrolyzed case, 7. flocculation agent volume pump, 8. hybrid reaction pipeline, 9. clear juice floating device, 10. approximately cloth vacuum suction filter, 11. accelerated clarifiers.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

The clear juice buoyancy system of the utility model as shown in Figure 1, comprise phosphoric acid volume pump 1 and clear juice case 2, phosphoric acid volume pump 1 and clear juice case 2 ligation case 3 respectively, fogbroom 4 is provided with in reaction box 3, reaction box 3 connects hybrid reaction chamber 5, and hydrolysis case 6 connects flocculation agent volume pump 7, and flocculation agent volume pump 7 connects hybrid reaction chamber 5, hybrid reaction chamber 5 connects clear juice floating device 9 by hybrid reaction pipeline 8, and clear juice floating device 9 connects approximately cloth vacuum suction filter 10 and accelerated clarifier 11 respectively.

The clear juice of sugarcane juice or syrup enters reaction box 3 from clear juice case 2, phosphoric acid volume pump 1 is added to after weighing phosphoric acid in reaction box 3, raw material is sent into hybrid reaction chamber 5 after being left by the air pocket in sugarcane juice or syrup by fogbroom 4, because the bubble in sugarcane juice or syrup is uneven, air pocket is helpless in floating, its quick rising disturbs normal floating on the contrary, so before material enters people's floating device, first allow air pocket leave.Be added in hybrid reaction chamber 5 after the weighing of flocculation agent in hydrolysis case 6 by flocculation agent volume pump 7, after leaving with air pocket, raw material is mixed, the preferred Polyscrylamide of flocculation agent, just generation effect after hydrolytic dissociation, bubbles volume controls slightly excessive, and Air Bubble Size is irregular or be unfavorable on the contrary too greatly floating.Pigment, starch, the bonded absorption of protein isocolloid particle is made in hybrid reaction chamber 5.Deliver to fully reaction in hybrid reaction pipeline 8 after having reacted, then enter juice floating device 9 floating separation clearly; Clear juice floating device 9 is separated scum silica frost and is eliminated by approximately cloth vacuum suction filter 10, and a small amount of throw out drops to accelerated clarifier 11, and clear juice then flows out from clear juice floating device 9, thus realizes clear juice floating-upward process.

The clear juice floating technology of the utility model system introduction is in the improvement of sugar refinery clarification process and utilization; proved by production practice; compare than all kinds of juice air-float technology (staying in theoretical investigation and pilot scale stage) clearly of being engaged in recent years; clear juice floating technology after improvement can well be applicable to mass-producing actual production; thus instead of traditional Syrup Flotation technique; reach improve clear juice quality, with low cost, reduce sugar transition and evaporation incrustation amount, obtain the object of the syrup of low colour, low turbidity and low sulfur-bearing.

Through the western sugar refinery of small cup 6 to 12 January in 2013 to subsider juice and enter floating device and accelerated clarifier fast supernatant juice sample out and carry out selective examination and chemically examine, the index contrast of supernatant juice and fast supernatant juice is as shown in table 1 below:

Table 1

Being also advantageous in that of the utility model system:

1, clear juice floats and can remove the non-sugar impuritiess such as most of colloid, lipid, protein with Syrup Flotation, makes that liquid glucose becomes limpid, viscosity declines greatly.

2, the percent of decolourization of Syrup Flotation is generally 15% ~ 20%, and from small cup western sugar refinery production actual achievement, the percent of decolourization that clear juice floats is more than 30%, and turbidity have dropped more than 50% especially, and its purity also increases.

3, meaning contrast, before evaporization process, clear juice floats can non-for major part sugar removing, greatly reduces the decomposition of the nonsugar such as organic acid, phenols in high temperature evaporation process and generates pigment and also reduce because the pH value sugar transition caused that declines loses.In addition, clear juice floats and the starch based impurity removing in clear juice, can also greatly reduce the viscosity of sugarcane juice, improve the mobility of sugarcane juice, thus improve evaporation performance.

The decomposition of material is always transformed into stable state by unsure state decomposition.The material of unsteady state is usually charged, and the material of steady state is usually that neutral or electric charge are more weak.Closed Circulation in Sugar Production be utilize electric charge attracting adsorption to remove non-sugar, after non-sugar transforms in evaporation, be just difficult to removing, major cause that why Syrup Flotation technique percent of decolourization is not high that Here it is.Phenol type substances in sugarcane juice is easy to decompose in evaporation, generates the pigment of more difficult removing, and this evaporates hyperchromic one of the main reasons.

Comparatively speaking, clear juice floats and compares Syrup Flotation and have the advantage of " take stopgap measures and also effect a permanent cure ", especially effectively can solve sulfurous acid sugar refinery and squeeze the difficult problem that middle and later periods in season sugarcane quality is poor, colloid is large, the sugared part can reducing evaporative process transforms loss, obtains the good syrup of low colour, low viscosity, low turbidity and low sulfur-bearing.Clear juice floating process costs is cheap, can effectively improve the quality of products and improve sugar yield, is very helpful to the market competitiveness strengthening enterprise.

The above is only to preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
