Description
Technical field
The present invention relates to continuous saponification process devices and methods therefors, and in particular to new-type compound lard continuous saponification process device and its side
Method.
Background technique
In daily use chemicals washing industry, traditional fat saponification technique has cauldron soap boiling, continuous saponification process (after grease continuous saponification process
Adverse current alkali cleaning, centrifuge separation) and neutralize the techniques such as soapmaking (neutralization of highly pressured hydrolysis distilled fatty acid).Cauldron saponification process steam
Consumption is high, and production efficiency is low, and the period is long, unstable product quality, while obtaining that by-product sugar water content is low, and subsequent glycerol purification needs
A large amount of steam are consumed, which is gradually eliminated.The technique of conventional grease continuous saponification process is continuously to be saponified grease, caustic soda
Soap base and sugar water separation are carried out afterwards, and thick soap is centrifugated acquisition soap base after carrying out adverse current alkali cleaning again, which puts into big, work
Skill control is complicated, although energy consumption is low compared with cauldron saponification, requires height to oil quality, the processing of by-product sugar water is still consumed energy higher.In
It is through highly pressured hydrolysis by grease into fatty acid mixed with soap preparing process, by distilation, the fatty acid neutralization with alkali of acquisition
Continuous soap preparing process, the product with stable quality worked it out in this way, production efficiency is higher, but complex process, and production process high temperature is high
Pressure, the high requirements on the equipment, investment are huge, so production cost is also very high, while controlling production capacity and requiring height, are not suitable for small rule
Mould production, otherwise production cost is too high.In addition, there are also patent report saponification to use amount of grease and partial fatty acid mixing soap
Chemical industry skill, this method causes grease fast reaction using fatty acid saponification heat, although equipment investment is compared with continuous saponification process and neutralization
Soap preparing process is small, but fat saponification rate is lower, and 20% fatty acid is at least used in formula, is not full grease formula, raw material
It is at high cost.

Thick soap also delivers into Homogenizing pump；Thick soap and salt water continue to be saponified in Homogenizing pump；
4, continue the material after saponification in Homogenizing pump and be transported to aging a few hours in the aging kettle with stirring, obtain qualified soap base.
In step 1, the preparation method of compound lard is: the theoretical amount of monomer oil is set in computer, opens solenoid valve will
A certain oil is put into from oil storage tank with oil tank, and when reaching specified amount, the solenoid valve is automatically closed；Another solenoid valve is opened, it will
Another oil is also placed in from oil storage tank with oil tank, and when reaching specified amount, the solenoid valve is automatically closed；Until reaching with oily total amount
When, stop with oil；It is finished with oil, opens stirring, take mixing oil sample, measured saponification value, opened after qualified and match oil tank bottom solenoid valve,
Oil is put into mixing oil tank.
In step 1, compound lard temperature is 105~110 DEG C；The mass concentration of alkali is 20%, alkali, oily ratio be 0.450~
0.460。
In step 2, saponification tower pressure interior force control in 0.03~0.08MPa, the tower top temperature control of saponification column 110~
130 DEG C, the saponification time is 1 hour.
In step 3, the mass concentration of salt water is 10%；Brine feed amount is the 15% of oil mass.
In step 4, ageing time is 2 hours in aging kettle.
The invention has the following advantages that
1, compound lard and caustic soda enter saponification column after emulsifying by homogenizer, and the thick soap and salt water that saponification column comes out pass through again
Matter pump continues to be saponified, finally by obtaining qualified soap base after aging kettle aging；Conventional continuous saponification process is added before saponification column
Salt water is added after being transferred to saponification column outlet, and saponification leading portion alkali oil ratio is high, and more conventional continuous saponification process is easier to obtain higher soap
Rate.
2, thick soap and salt water can further promote saponification by Homogenizing pump homogeneous, to obtain continuous with routine
Saponification rate as saponification is final.
3, the glycerol that technique saponification generates is evenly distributed in soap base, does not have by-product sugar water.
4, using full grease formula, fat saponification is high-efficient, soap base stay in grade.
5, equipment investment is small, and technology controlling and process is simple, and production capacity, start-stop can be adjusted flexibly according to capacity requirements within the scope of production capacity
Vehicle is very easy to.
6, the more traditional continuous saponification process technique of this process energy consumption is greatly lowered, while not needing to refine sugar water, is a kind of green
Color environment-protective process.
