Abstract
The present invention relates to quick self-drying, sulfur-fixed and waterproof briquette (coke) which is manufactured by using powder coal (breeze) and coal slurry as raw materials and using ground quick lime powder as an adhesive agent. Because the present invention has the advantages of abound resources of quick lime, easy processing and low price, the processed briquette can be quickly self-dried, the intensity and waterproof capability can be rapidly formed, and the sulfur-fixing and thermal stability is high. Therefore, the present invention can satisfy the requirements for performance of the briquette in an overall process from briquette self production to consumption and has wide industrialization prospects. The present invention can have the extrusive effects of technology simplification, consumption reduction, quality increase and benefit increase when used for fertilizer industry technical innovation of coal acidified briquette gas manufacture used at present.
Description
Moulded coal＜Jiao of a kind of quick self-drying, solid sulphur, waterproof 〉.The application relates to moulded coal＜Jiao of a kind of quick self-drying, solid sulphur, waterproof 〉, the particularly moulded coal of industrial use, formed coke.Belong to resource and environment field category.
This moulded coal＜Jiao〉binding agent that uses is 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 the fine grinding quicklime powder that the caustic lime block grinding is become to account for more than 95% by 200 mesh sieve hole fine powders to replace slaked lime powder, can make the problems referred to above obtain the correction of essence.This mainly be because: when adopt amount of water be fine grinding quicklime weight 90～200% and when the condition of excessive agitation got off to clear up fine grinding quicklime powder for a long time, its digestion process and process of setting will be because of hydrated product Ca[OH]
2Colloid forms coherent structure and cohesive strength and becomes a successive process.
Be further described 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%, adding grinding becomes to account for 7 parts of fine grinding quicklime powders more than 95% and carry out secondary stirring by 200 mesh sieve hole fine powders, churning time must not be greater than 60 seconds, and it is moulding in the briquette shaper more than the 25MPa that the back 5 minutes planted agents of stirring send raw material into forming pressure.Balling-up meeting about 10 minutes raises the temperature of coal briquette owing to the CaO hydration heat and evaporates part moisture content, 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 of breezes, 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 (2)
1. moulded coal＜Jiao of a quick self-drying, solid sulphur, waterproof 〉, it is characterized in that using smalls＜breeze〉and coal slime be raw material, make binding agent with granularity for the fine grinding quicklime powder that accounts for more than 95% by 200 mesh sieve hole persons, make according to following mixing ratio by weight:
Smalls＜breeze 〉: coal slime: fine grinding quicklime powder=(10～85): (0～85): (5～15).
2. moulded coal＜Jiao of claim 1 〉, it is characterized in that it being by smalls＜breeze and the moisture content total amount calculated of the as received basis of coal slime be add 90～200% of fine grinding quicklime powder weight.
