Description
Technical field
The utility model relates to sugaring Controlling System, is specifically related to a kind of sugaring process sulfite method mixing juice, defeco-sulfitated juice flow Constant Current Control System.
Background technology
In sulfurous method sugar refining technology, Sulphitation and Neutralization is an important procedure of its production process, intensity of sulfitation is the main factor affecting sulfurous method clarifying effect, improve intensity of sulfitation, the calcium sulfite precipitation capacity generated increases and can adsorb and removes comparatively polychrom and other impurity, and clear juice calcium content and ash content reduce, and colloidal content also reduces to some extent, also higher to the removing of phenolic material, clear juice color and luster is more shallow.But intensity of sulfitation has a significant impact the sedimentary form of producing, when sugarcane juice intensity of sulfitation is lower than 10cc, the condensation product mainly calcium phosphate precipitation generated after adding ash heating, calcium sulfite is few, sedimentable matter is few, clarifying effect is poor, when intensity of sulfitation is very different more than situation during 15cc, now calcium sulfite crystal is distributed more widely, crystal and agglomerate compact siro spinning technology, the thicker and compacted mass of throw out, but calcium sulfite increases, commerieal sugar sulphur content may be caused too high, the quality of impact sugar.
At present, most of sugar refinery is due to unstable when mixed juice amount fluctuation makes the material sprayed spray; There is the fierceness change of pressure and flow instantaneous, stable suction sulphur negative pressure can not be formed, therefore SO
2absorption also there will be fierce sudden change, can not get stable stove drying effect, thus do not reach the object of stove drying, the throw out of generation is shaky, mud juice suction strainer situation is undesirable; In making simultaneously and time milk of lime amount used increase, affect the consumption of whole Closed Circulation in Sugar Production working ability, quality product and supplementary material, equally, due to the fluctuation of defeco-sulfitated juice amount, make second-heating difficult control of temperature, compliance rate does not reach processing requirement, and what affect settling tank puts juice, finally affects quality, withdrawal etc.
Simultaneously, defeco-sulfitated juice quantity of reflux is by Artificial Control, and the personal experience only by scale and operative employee judges to control, and does not slightly note observing or occurring hysteretic operation, all directly cause the mixing juice amount unusual fluctuations entering neutralizer, mixed juice case time serious, can be caused to find time.Because the mixing juice amount entering neutralizer is unstable, cause production aspect and occur following fluctuation: 1, and intensity of sulfitation arrival rate do not reach technic index check requirements; 2, evaporate second-heating temperature fluctuation, index arrival rate does not reach operation index requirement; Because the labile factor of above two aspects affects, make at the bottom of sedimentation tank mud shaky, discharge clear juice and have some setbacks, meanwhile, make filtration device inhale mud influenced, both reduced the treatment capacity of mud juice, and reduced again the quality of filtered juice; 3, because pipeline pressure changes greatly, easily cause the explosion of pipeline connecting parts flange gasket, there is potential safety hazard.
