Description
Technical field
The present invention relates to calcium hydroxide production field, and in particular to the stone that a kind of utilization precipitated calcium carbonate factory production shuttle is produced
The method that mortar and waste residue waste material produce calcium hydroxide.
Background technology
Calcium hydroxide is a kind of white powdery solids.Chemical formula Ca (OH) 2, is commonly called as white lime, calcium hydroxide, and the aqueous solution claims
Make clarification limewash.Calcium hydroxide has the general character of alkali, is a kind of highly basic.Calcium hydroxide is binary highly basic, but is only capable of being slightly soluble in
Water.Calcium hydroxide is widely used in the industry.
Many lime whites and waste residue waste material are generated during current precipitated calcium carbonate industry production, it is impossible to obtain effectively
Treatment, causes some available resources to waste, and pole is not environmentally.
The content of the invention
Defect and deficiency it is an object of the invention to be directed to prior art, there is provided a kind of simple structure, it is reasonable in design, make
With the convenient method for producing calcium hydroxide using lime white and waste residue waste material, the production method high degree of automation, sealing
It is good, can be by discarded object cycling and reutilization, energy-conserving and environment-protective.
To achieve the above object, the technical solution adopted by the present invention is：Its procedure of processing is as follows：
First, waste residue is unloaded：
Material is discharged into a trapezoidal hopper by haulage vehicle；
2nd, using the leftover bits and pieces in lime leasing；
3rd, it is homogenized：
Lime white and waste residue waste material are conveyed by auger and tentatively mixed, and add 1mm~10mm's in first order auger end
Quick lime carries out digestion reaction with wet stock, and quick lime and wet stock ratio are 0.1~0.5:1, and can be according to the dry and wet of material
The a small amount of water of degree supplement, then auger is homogenized by two-stage（Total length is not less than 20m）Stirring homogenizing（30min~60min）, make to do
Wet stock is evenly distributed, and homogenizing and digestion reaction have been carried out in whipping process, makes material dry and wet suitable, into loose sprills；
The bottom of homogenizing auger is deposited in through digesting again for a long time without complete calcium oxide is digested, because volume after digestion is complete
Expanding and become fluffy can progressively be delivered to elevator by auger；
4th, static digestion：
By the material of homogenization stage, static state digests more than 2h in being promoted to homogenizing bin by elevator, makes quick lime and moisture
Fully reaction is complete；
5th, roughing is got the raw materials ready：
After by the static digestion of more than 2h, material conveying auger to elevator is screened out simultaneously crushed stone by drum sieve
Discharge, then will tail over material and be delivered to the standby production in storehouse of getting the raw materials ready by auger；
6th, process：
The material in storehouse of getting the raw materials ready enters the ultra-fine grey calcium machine of alloy or pneumatic separator by charging auger, and the calcium hydroxide after processing enters
Enter product storehouse preservation.
Further, waste discharge slag, cinder device are equipped with described step five and step 6, can be with improve product quality
And content.
Further, pulsed dust-removing device is provided with described step two and step 3, to reach purify air, protection ring
The target in border.
The present invention has the beneficial effect that：A kind of utilization lime white of the present invention and waste residue waste material produce the side of calcium hydroxide
Method, the production method high degree of automation, good airproof performance can have discarded object cycling and reutilization, energy-conserving and environment-protective, the present invention
Simple structure, it is reasonable to set, the advantages of low manufacture cost.
Specific embodiment
This specific embodiment use technical scheme be：Its procedure of processing is as follows：
First, waste residue is unloaded：
Material is discharged into a trapezoidal hopper by haulage vehicle；
2nd, using the leftover bits and pieces in lime leasing；
3rd, it is homogenized：
Lime white and waste residue waste material are conveyed by auger and tentatively mixed, and the quick lime of 5mm is added in first order auger end
Digestion reaction is carried out with wet stock, quick lime and wet stock ratio are 0.1~0.5, and can be few according to the humidity of material supplement
The water of amount, then auger is homogenized by two-stage（Total length is not less than 20m）Stirring homogenizing 50min, makes dry and wet material be evenly distributed,
Homogenizing and digestion reaction are carried out in whipping process, has made material dry and wet suitable, into loose sprills；Without the complete oxidation of digestion
Calcium precipitate in the bottom of homogenizing auger through digesting again for a long time, after because of volumetric expansion and becoming fluffy meeting after digestion completely
Elevator is progressively delivered to by auger；
4th, static digestion：
By the material of homogenization stage, static state digests more than 2h in being promoted to homogenizing bin by elevator, makes quick lime and moisture
Fully reaction is complete；
5th, roughing is got the raw materials ready：
After by the static digestion of more than 2h, sample conveying auger to elevator is screened out simultaneously crushed stone by drum sieve
Discharge, then will tail over material and be delivered to the standby production in storehouse of getting the raw materials ready by auger；
6th, process：
Get the raw materials ready storehouse material by charging auger enter the ultra-fine grey calcium machine of FZQ type alloys or pneumatic separator, the hydrogen-oxygen after processing
Change calcium to be preserved into product storehouse；
7th, packed and transported：
