Description
Technical field
The present invention relates to a kind of detection devices of raw burning rate of digestion precipitation method intelligence lime.Belong to material property inspection
Technical field is related to the inspection of the life burning rate content's index of lime, be widely used in metallurgy, chemical industry, calcium carbide, chlor-alkali, building,
The industries such as firepower electrical plant desulfurization.
Technical background
Lime is the material that a kind of chemical property is active, respond is strong, is as lime stone by made of high-temperature calcination,
Its main component chemical formula is CaO.Calcium oxide is easy to that digestion reaction occurs with water, generates calcium hydroxide, and release heat.By
Very low in the solubility of calcium hydroxide in water, under room temperature, solubility is only 1.29g, so limewash will go out after saturation
The precipitation of existing solute, is deposited in the bottom of container.These techniques and phenomenon all provide theoretical foundation for the detection of lime quality.
The raw burning rate of lime is to characterize an extremely important reference index of lime quality quality, and raw burn is that lime stone is not complete
Complete to decompose, remnants have lime stone；Burning is that limestone calcination is excessive, and the crystal grain of calcium oxide is enabled to grow up, and activity reduces, and is occurred with water
The ability of digestion reaction substantially reduces, and lime densification degree increases, and raw burn and burning are unfavorable for the use in later period production,
So the raw burning rate of lime is to evaluate an important indicator of lime quality.
The inspection principle of the raw burning rate of lime is that quick lime meets water and reacts generation calcium hydroxide rapidly, is detached from lime block,
And it is deposited to solution bottom, the part of digestion reaction is not made a living the part of burnt lime and Extend position, is weighed its weight, is passed through
Residual weight accounts for the numerical value of former lime gross weight to measure the size for determining raw burning rate.
In metallurgy industry, raw burn lime can bring error to the proportion of raw material, the adjustment of basicity of slag can be brought it is unfavorable because
Element, Extend position is since its porosity is lower, and airtight air vent largely exists, and produces large effect to converter slag-making,
Be unfavorable for that scorification in molten iron reacts quickly completes, so the life burning rate index in metallurgy industry lime is an important ginseng
Examine index.
In calcium carbide industry, raw burn lime needs to further decompose into quick lime in furnace of calcium carbide, and consumption of calorie increases electricity
Consumption, and also will affect the normal proportion of furnace charge, upset the normal operating of furnace of calcium carbide.Extend position hard and compact, poor activity, drop
Low reaction speed, and after volume-diminished, contact area is reduced, and is caused charging resistance to decline, is lifted on electrode, is grasped to furnace of calcium carbide
It is unfavorable to make.
At this stage, the inspection of raw burning rate generallys use mode manually, with directly flushing with tap water lime, to water
After limpid, remaining material is dried, is weighed, raw burning rate is calculated.What is more,
The size of raw burning rate is directly judged by the experience of vision, reliability and the true value of data have sizable
Gap, the preciseness of data also comparable deficiency；In addition directly flushing with tap water lime is used, a large amount of alkaline sewage is caused,
It is directly discharged in sewer, biggish pollution is produced to environment, biggish work load is brought to later period sewage treatment.
The raw burning rate index of lime is all at this stage certainly there are no corresponding country or the examination criteria of industry, each enterprise
Oneself establishes the company standard of oneself, is the production service of oneself；Testing principle between different enterprises is almost the same, but detect
Methods are there is difference, and there is also more disunities for detection means, to bringing not between enterprise to mark work
Benefit influences.
Summary of the invention
The purpose of the present invention aims to solve the problem that existing technical problem, provides a kind of raw burning rate of digestion precipitation method intelligence lime
Detection device, provide a kind of intelligence, accurately and fast, convenient detection device, and realize the automatic inspection of the raw burning rate of lime
It surveys.
The present invention is applicable not only to the inspection of the raw burning rate of metallurgy industry quick lime, is also applied for calcium carbide, chlor-alkali, chemical industry
Etc. the inspection of the raw burning rate of lime in industries, there is extensive industrial applicability.
The realization of the object of the invention mainly executes by following technical solution:

0~10h of range is set.
A kind of detection device of the raw burning rate of intelligence lime, it is characterized in that Circularhole diameter or square hole side length are 1mm~10mm.
Beneficial effect
The detection device of a kind of raw burning rate of digestion precipitation method intelligence lime of the present invention, with prior art and detection
Means are compared, and are had the advantage that
1, the automation of the raw burning rate detection of lime is realized；
2, human error and mistake are avoided, labor intensity is reduced；
3, testing water used can be used for multiple times, and without being discharged into sewer, avoid dirt of the alkaline sewage to environment
