Description
Technical field
The utility model relates to a kind of laboratory apparatus for treating steel slags, is used for studying the technology of the free calcium oxide content of effective reduction slag.Be the laboratory apparatus of the processing parameter when being used to explore industrial applications, lay the first stone for promoting novel process.And can be used to study the specific absorption of slag to carbonic acid gas.
Background technology
Along with the development of national recycling economy, require metallurgy industry that waste resource is realized utilizing again, particularly utilizing again of metallurgical slag, waste gas becomes the focus that the metallurgy industry recycling economy is paid close attention to.Most critical factor as slag comprehensive utilization is the stability of slag, and influencing stability has multiple reason, and wherein the decomposition of the aquation of free calcium oxide is a major cause.These free calcium oxides in the slag have all stood about 1700 ℃ high-temperature calcination, its compact structure, and crystalline particle is thick, and hydration rate is extremely slow, at normal temperatures than the more difficult aquation of (1400 ℃) f-CaO of the calcination in the cement clinker.Simultaneously, in the slag f-CaO solid solution a certain amount of FeO, MgO and MnO, and its content surpassed 15%, forms zonal structure, and its response capacity is reduced, and has the slow characteristics of aquation.When f-CaO contacts with water, can clear up gradually and produce Ca (OH) 2, volume increases about one times, makes and produces internal stress in the slag, and internal stress increases and increases with f-CaO content, when it surpasses the bonding force of slag itself, will cause slag to burst apart even efflorescence.
But, also do not have a kind of being specifically designed to explore the laboratory apparatus that slag is handled the industrial applications processing parameter at present.
Summary of the invention
The purpose of this utility model is a kind of laboratory apparatus for treating steel slags that can effectively explore the free calcium oxide processing parameter in the elimination slag of design.And the energy measurement slag is to the carbon dioxide absorption rate.
The technical solution of the utility model: laboratory of the present utility model comprises processing vessel with apparatus for treating steel slags, processing vessel adopts the slag processing vessel with temperature control, pressure control, the slag processing vessel is connected with vacuum pump by pipeline, and the slag processing vessel produces container by pipeline with valve and steam and is connected.
Described laboratory apparatus for treating steel slags, master control processing vessel have the mouth of pipe and the valve that feeds carbonic acid gas.
Placement of multiple layers slag placing plate and support thereof in the described laboratory apparatus for treating steel slags, slag placing plate.
Described laboratory apparatus for treating steel slags, the master control processing vessel is equipped with Explosion-proof valve.
Described laboratory apparatus for treating steel slags, steam produces container Explosion-proof valve is installed.
The beneficial effects of the utility model:
Processing parameter when this laboratory is used to explore industrial applications with apparatus for treating steel slags lays the first stone for promoting novel process.Have following functional characteristics:
(1) can feed carbonic acid gas simultaneously and water vapour is handled slag, find the free calcium oxide of handling in the basically eliminate slag of back, increase substantially the processing parameter of the stability of slag performance, thereby improve the steel slag utilization rate.
(2) can free control pressure and variation of temperature, pressure range 0.1～0.5MPa, 100～300 ℃ of range of temperature;
(3) can the quantitative assay slag to the specific absorption of carbonic acid gas.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: the 1st, steam produces reservoir heater, the 2nd, Explosion-proof valve, the 3rd, pressure controller, the 4th, temperature regulator, the 5th, master control processing vessel and steam produce the valve on the container connecting pipeline, the 6th, the mouth of pipe of carbonic acid gas and valve, the 7th, demixing plate, the 8th, vacuum pump 9 is vacuum pump valves, and 10 steam produce container, 11 master control processing vessels.
Embodiment
Fig. 1 is a structural representation of the present utility model: master control processing vessel 11 of the present utility model has temperature regulator 4 and pressure controller 3, master control processing vessel 11 is connected with vacuum pump 8 by pipeline, master control processing vessel 11 produces container 10 by pipeline with valve 5 and steam and is connected, and establishes slag placing plate 7 in the master control processing vessel.Master control processing vessel 11 feeds the mouth of pipe and the valve 6 of carbonic acid gas in addition.The support 12 that placement of multiple layers slag placing plate is arranged in the master control processing vessel 11.Master control processing vessel and steam produce container Explosion-proof valve 2 all are installed.
Slag is handled operating process: slag is placed on the demixing plate 7, at first uses vacuum pump 8, container 11 is carried out vacuum-treat, treat that pressure controller 3 displayed values are near vacuum after, close vacuum pump 8 and valve 9, stop to vacuumize.By well heater 1 heating container 10, behind the generation saturation steam, open the valve 5 between container 11 and the container 10, when treating pressure controller 3 displayed values near experimental design pressure, valve-off 5.Container 11 is carried out temperature control, and pressure control is handled, and temperature and pressure can freely be adjusted in instrument satisfies scope.Keeping this state finishes until experiment.
The carbon dioxide absorption rate is measured: slag is placed on the demixing plate 7, at first uses vacuum pump 8, container 11 is carried out vacuum-treat, treat that pressure controller 3 displayed values are near vacuum after, close vacuum pump 8 and valve 9, stop to vacuumize.From valve 6, feed carbonic acid gas then, when treating that pressure controller reaches 0.1mpa, valve-off 6.Container 11 is carried out temperature control, and pressure control is handled, and temperature and pressure can freely be adjusted in instrument satisfies scope.Keeping this state finishes until experiment.Treat that vessel temp returns to test at the beginning, record pressure controller indicating value P
0. then the carbon dioxide absorption rate is P
0/ 10{%}.
By this device control vapor temperature and pressure, come slag is handled.Principle is the free calcium oxide reaction that utilizes in water vapour and the slag, generates stable structure, improves steel slag stability.Testing data can be widely used in engineering project, improves steel slag stability.
