Abstract
The present invention relates to a quick self-drying sulfur-fixing and water-proofing briquette (formed coke). It is made up by using conny (coke powder) and coal slime as raw material, and using fine-ground caustic lime powder as binder. By adopting caustic lime which is rich in resource, easy to process and low in cost, it can make the produced briquette quickly self-dry, quickly form strength and water-proofing property, fix sulfur and possesses high thermal stability. When it is used in the present chemical fertilizer industry usig carbonization of briquette to prepare gas for technical transformation, it can obtain the obvious effects of simplifying process, reducing consumption, raising quality and increasing benefits.
Description
The moulded coal (Jiao) of a kind of quick self-drying, solid sulphur, waterproof.The present invention relates to various moulded coals, the formed coke of a kind of moulded coal or formed coke, particularly industrial use, the binding agent that this moulded coal (Jiao) uses is a fine grinding quicklime powder.
Traditional lime coal briquette is the slaked lime powder that adds in smalls more than 20%, sends in the charing jar after the briquette shaper moulding and feeds CO
2Gas carries out about 9～12 hours charcoal acidification, so that make moulded coal acquisition intensity and have certain water-proof function.The noncombustibles matter that this method adds is more, complex process, and the hot and cold intensity difference of product, thermostability is especially bad, and economic performance is not good enough.
Use the present invention---promptly use fine grinding quicklime powder to replace slaked lime powder, can make the problems referred to above obtain the correction of essence.This mainly be because: when adopting the only water yield and clearing up fine grinding quicklime powder under certain condition, its digestion process and process of setting will be because of hydrolysate Ca (OH)
2Coherent structure that colloid forms and cohesive strength and become a successive process.
That the invention will be further described is as follows below in conjunction with example:
Embodiment 1: get 60 parts of smalls, 33 parts of coal slimes, the as received basis moisture content that mixes back control mixture is about 14%, add 7 parts of fine grinding quicklime powders and carry out secondary stirring, churning time must not be greater than 60 seconds, and stirring evenly back 5 minutes planted agents, raw material is sent into forming pressure is moulding in the briquette shaper more than the 25MPa.Balling-up is understood about 10 minutes owing to the CaO hydration heat makes the temperature rising of coal briquette and evaporates part moisture in moulding, thereby makes coal briquette acquisition intensity and possessed certain water-proof function, directly outdoor storage.
Embodiment 2: get 10 parts of smalls, and 80 parts of coal slimes, mixed as received basis moisture content is controlled at about 20%, adds 10 parts of fine grinding quicklime powders.All the other technologies are with embodiment 1.Variation and performance are also with embodiment 1 after the balling-up.
Embodiment 3: get 85 parts in breeze powder, control its as received basis moisture content about 15%, add 15 parts of fine grinding quicklime powders.Change all with embodiment 1 after all the other technologies and the balling-up.
Claims (4)
1, the moulded coal (Jiao) of a kind of quick self-drying, solid sulphur, waterproof is characterized in that using smalls (breeze) and coal slime to be raw material, makes and make binding agent with fine grinding quicklime powder.
2, according to the described moulded coal of claim 1 (Jiao), it is characterized in that described smalls (breeze) content is 10～85%, coal slurry content is 0～85%, the content of fine grinding quicklime powder is 5～15% (all being weight percentage).
3,, it is characterized in that the moisture total amount of calculating by the as received basis of smalls (breeze) and coal slime is add 90～200% of fine grinding quicklime powder weight according to the described moulded coal of claim 1 (Jiao).
4, according to the described fine grinding quicklime powder of claim 1, its granularity is for to account for more than 95% by 200 mesh sieve hole persons.
