Description
Technical field
The utility model relates to the cane sugar manufacture field, is specifically related to a kind of Sulphitation and Neutralization reaction tower.
Background technology
In the sulfurous method sugar refining technology, neutralization reaction is the key link of clarifying syrup, and its principle is to add sulfurous gas and milk of lime, reaction to form calcium sulfite with the absorption non-sugar impurities in syrup, reaches the purpose of peace and quiet syrup.
The effect of neutralization reaction has material impact to sulfurous method white sugar quality and sugar yield.Present sulfitation sugar mill is normally with after the stove drying of syrup process, add milk of lime in the tail pipe of pipeline sulfitator, then entering a loose gas bucket falls apart gas and simple the 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 because the Main Function of loose gas bucket is the sulfurous gas that dissipates the air in syrup and cannot absorb completely, do not consider the chemical reaction function, therefore loose gas bucket designs to get small volume, there is no agitator, this causes the mixing of sulfurous gas, milk of lime, syrup inhomogeneous, cause the purification effect of syrup low, affect quality product and sugar total recovery.In addition, fail the abundant lime that reacts and sulfurous gas along with syrup enters into the subsequent production link, produce after reaction, follow-up evaporating pot incrustation is increased, reduced evaporation performance.
In recent years sugar refinery is in order to improve neutralization reaction efficient, also uses some utility appliance to add as: rotary hopper-type that grey device, overflow type add grey device, duct type adds grey device, shock flow type reactor, defeco-sulfitated juice enhanced reactor etc.
It is a kind of equipment of just adjusting by regulating rotating bucket rotating speed and milk of lime overflow plate that rotary hopper-type adds grey device, and the master adds grey device and prelimer can be arranged on an axle simultaneously, adds simultaneously ash from opposite two aspects.Simple in structure, convenient and practical, but syrup and milk of lime, sulfurous gas reaction needed room and time have been ignored, rotary hopper-type add grey device add the complete rear syrup of ash 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 by moving left and right (moving with the suspension pulley) main ash and preliming chute of adding, and regulates and accesses the milk of lime amount, reaches the purpose of regulating main, pre-ash amount.It is not high to the control accuracy of ash quantity fed that overflow type adds grey device, has control hysteresis to a certain degree, and overflow advances ash and cause fully hybrid reaction of syrup and milk of lime, and defeco-sulfitated juice pH part is too high or too low.
Duct type adds grey device and is mainly used in adding ash; Large when amount of finish, when the syrup flow is large, irregular for avoiding adding ash, can add ash at several overflow ports (trumpet type funnel) simultaneously.Duct type adds grey device and mixes with syrup with certain mobility, obviously is better than front two kinds of equipment, and advances ash a plurality of overflow ports are arranged, and it is more uniform relatively adding ash.But thisly add grey device and do not have reaction time, add namely that namely to walk to cause neutralization reaction not exclusively to enter settling vessel, the particularly impact for accelerated clarifier large especially, easily cause turning at the end of settling vessel.
Shock flow type reactor and defeco-sulfitated juice enhanced reactor are all improved on several shortcomings that add grey device in front, and the reaction required time that adds after ash is also paid special attention to, and have especially strengthened the mixture strength of syrup and milk of lime, promote neutralization reaction.But these two kinds of reactors are easily deposited slag incrustation, and situation occurs to stop up.
