Description
Technical field
The present invention relates to a kind of method of the briquet for the manufacture of comprising carbon support, wherein said carbon support stands to mix in the situation that adding water vapor with bonder system, and the mixture obtaining at this forms as briquet through being squeezed.
Background technology
When becoming piece (Steinkohlebrikettierung) in early days, hard coal first for manufactured the carbon support of piece by ickings, burns for being used as household fuel or being used in industrial burning bed.Therefore, know a large amount of methods that becomes piece for carrying out hard coal.For COREX/FINEX method of the pig iron for the manufacture of liquid, hard coal becomes piece to have very high meaning, because these methods, based on fixed bed process, are manufactured described fixed bed by the carbon support that becomes piece in fixed bed process.
Also, in the method representing by " smelting reduction process " this professional concept at these, together with the siderophore of the carbon support of one-tenth piece and process prereduction and filler, be loaded on the fixed bed surface of so-called melting gasifier.In described melting gasifier, the described siderophore through prereduction is finally reduced, and produce the pig iron of melting and the slag of melting, obtain the pig iron of described melting and the slag of melting once in a while by slag notch.Heat necessary for melting process provides by means of oxygen by the gasification of the carbon support of described one-tenth piece.In the situation that giving out heat, penetrate described curing bed at the hot gas of this generation, and leave described curing bed on described curing bed surface.In the adverse current with respect to described hot gas, solidify bed described in the pig iron of melting and the slag penetration of melting, and accumulate in the nethermost region of described curing bed, namely in the groove of so-called hole.For these processes, enough perviousness of described curing bed are essential, described perviousness become described in depending in the time being loaded on described curing bed surface piece carbon support granularity and solidifying on bed surface, solidifying bed in other words in during condition under the granule stability of carbon support of described one-tenth piece.Therefore the granularity of the carbon support of described one-tenth piece should have enough large coarse grain share and limited to small-particle share (Unterkornanteil) in the time being loaded on described curing bed surface.From the starting material of described carbon support by sieve to set suitable, for the granularity of the carbon support of loaded one-tenth piece in the time handling until must not be because mechanical stress suffers obvious destruction before being loaded on described curing bed surface.In addition, the granularity of the carbon support of described one-tenth piece should retain enough large coarse grain share and limited to small-particle share under described condition of solidifying on bed surface or during in solidifying bed.Become piece carbon support, in the time handling until prevent that the resistivity of the destruction of its granularity is called as low temperature intensity before being loaded on described curing bed surface, form under condition carbon support, on described curing bed or during in described curing bed of piece and prevent that the opposing intensity of the damage of its granularity is called as hot strength.
In the COREX/FINEX of the pig iron for the manufacture of liquid method, generally hard coal is used as to carbon support.Commercial common hard coal generally only has the share of 30-70% coarse grain, and this share can directly be loaded as the carbon support that becomes piece.Described compared with small-particle share in order also to use in the carbon support that becomes piece, its briquetting is applicable to.For anthracitic fritter, described low temperature intensity and described hot strength are natural characteristics, different from described anthracitic fritter, the low temperature intensity of the carbon support of the one-tenth piece of producing in the time of briquetting and hot strength pass through the kind of used method and the feature of enforcement is advantageously affected.
By US No 6332911, WO200250219, WO2004020555, WO2005071119, WO9901583, WO2010081620, hard coal briquetting method is illustrated together with COREX/FINEX.Wherein mention a large amount of possible, for the bonder system of this purposes, wherein also mention starch and polymkeric substance.In mentioned embodiment, correspondingly tackiness agent is mixed with liquid form and the coal that needs to be pressed into piece.But, with solid-state granular until the starch that the denseness of powdery exists and polymkeric substance-especially PVA must mix with higher moisture content volume-1 part dry tamanori and at least 10 parts of water or more water, for generation of the liquid tamanori that can handle.At doping water, very little time, uniform distribution tamanori, in coal is more difficult.Easily form deformed thing.Reduce thus the binding ability of described tamanori, this point then must be compensated by more consumption of tamanori.But this point is unwelcome for cost reason.If improve for this reason the moisture content volume of described tamanori, although so described tamanori can distribute better in coal, but cause very wet mixture, described very wet mixture is not easy to be pressed into piece, because described wet mixture easily forms bridge joint (Br ü ckenbildung) with the degree increasing due to its stickiness in the charging of briquet pressing machine, and therefore described briquet is often bonded at the inside of the mould of pressing machine.
But, for being necessary that the use of briquet in COREX/FINEX method of the liquid pig iron described, not only about the optimization of the intensity of described briquet and about the restriction for the humidity of described briquet before using, briquetting process is controlled, for the manufacture of the liquid pig iron.
Situation about the starch of powder type and coal being mixed using in water vapor has also been described in US1121325.But, first must manufacture water vapor cumbersomely, this increases the weight of the burden of the economy of described method.
In file US3018227A, US4557733A, US1871104A, to being illustrated manufacturing the steam using in the environment of briquet, but in the mixing step of carbon support and bonder system, do not add the waste vapour of other method steps.
Summary of the invention
Task of the present invention is, is provided for manufacturing a kind of method and a kind of device of briquet, and described method also can realize economic technology controlling and process in the time of the water vapor using for carbon support and bonder system are mixed.
This task is resolved by a kind of method of the briquet for the manufacture of comprising carbon support, wherein in the situation that adding water vapor, makes described carbon support stand to mix together with bonder system, and the mixture obtaining at this is formed as briquet through being squeezed.
Describedly be characterised in that by method of the present invention,
Implement from least one step in the step of following set, described set is made up of the following step:
