Description
Technical field
The present invention relates to cane sugar manufacture field, be specifically related to a kind of Sulphitation and Neutralization reaction tower.
Background technology
In sulfurous method sugar refining technology, neutralization reaction is the key link of clarifying syrup, and its principle is in syrup, add sulfurous gas and milk of lime, and reaction forms calcium sulfite to adsorb non-sugar impurities, reaches the object of peace and quiet syrup.
The effect of neutralization reaction has material impact to sulfurous method white sugar quality and sugar yield.Current sulfitation sugar mill normally by syrup after stove drying, milk of lime is added in the tail pipe of pipeline sulfitator, then enter a loose gas bucket and carry out loose gas and simple mixing, because a large amount of sulfurous gas and milk of lime almost add in syrup simultaneously, initial reactive concentration is high, and chemical reaction is very violent.And due to the Main Function of loose gas bucket be the air dissipated in syrup and the sulfurous gas cannot absorbed completely, do not consider chemical reaction function, therefore loose gas bucket designs to obtain small volume, there is no agitator, this causes the mixing of sulfurous gas, milk of lime, syrup uneven, cause the purification effect of syrup low, affect quality product and sugar total recovery.In addition, failing the lime of fully reaction and sulfurous gas enters into subsequent production link along with syrup, produces after reaction, follow-up evaporating pot incrustation is increased, reduces evaporation performance.
In recent years sugar refinery is in order to improve neutralization reaction efficiency, also use some utility appliance as: rotary hopper-type adds grey device, overflow type adds grey device, duct type adds grey device, shock flow type reactor, defeco-sulfitated juice enhanced reactor etc.
It is that master adds grey device and prelimer can be installed on a shaft simultaneously, adds ash from contrary two aspects simultaneously by regulating rotating bucket rotating speed and milk of lime overflow plate height to carry out a kind of equipment adjusted that rotary hopper-type adds grey device.Structure is simple, convenient and practical, but ignore syrup and milk of lime, sulfurous gas reaction needed room and time, rotary hopper-type add grey device add ash complete rear syrup directly enter mixed juice case then pump to subsequent processing, milk of lime, sulfurous gas, syrup have little time abundant hybrid reaction, cause the problems such as follow-up workshop section incrustation is many, poor product quality.
Overflow type adds grey device, and by moving left and right, (moving with suspension pulley) is main adds ash and preliming chute, regulates and accesses milk of lime amount, reach the object regulating main, pre-ash quantity.It is not high to the control accuracy of ash quantity fed that overflow type adds grey device, there is control hysteresis to a certain degree, and overflow is entered ash and caused syrup and milk of lime cannot abundant hybrid reaction, and defeco-sulfitated juice pH is locally too high or too low.
Duct type adds grey device and is mainly used in adding ash; When amount of finish is large, syrup flow is large, irregular for avoiding adding ash, ash can be added at several overflow port (trumpet type funnel) simultaneously.Duct type adds grey device and mixes with syrup with certain mobility, is obviously better than first two equipment, and enters ash and have multiple overflow port, and it is more uniform for relatively adding ash.But thisly add grey device and do not have reaction time, namely add and namely walk to cause neutralization reaction not exclusively to enter settling vessel, the impact particularly for accelerated clarifier is large especially, and that easily causes settling vessel turns over the end.
Shock flow type reactor and defeco-sulfitated juice enhanced reactor all above, several shortcoming adding grey device are improved, and also paying special attention to, especially strengthening the mixture strength of syrup and milk of lime to adding the reaction required time after ash, promote neutralization reaction.But these two kinds of reactors easily deposit slag incrustation, there is blocking situation.
