Abstract
The present invention relates to a moulding method for clean briquettes. The operation is simple and convenient. Briquettes prepared according to the method have the advantages of high thermal stability, good activity, low carbon returning rate, cost reduction and environment pollution elimination. The technical process of the present invention comprises the following steps: 25kg of kaoline, 25kg of silicate, 15kg of aluminate, 15kg of bentonite and the 5kg of gypsum are fetched out; after the raw material is pulverized at the normal temperature, the pulverized raw material is stirred and mixed by a mixing stirrer, and powdery additive is prepared; the powdery additive is added to 900kg of powdered coal, and the powdery additive and the powdered coal are stirred and moulded.
Description
One, technical field:
The present invention relates to a kind of forming method of clean moulded coal, it is mainly used in fields such as chemical fertilizer industry, Industrial Boiler and dining room, dining room tea furnace.
Two, background technology:
China is a big coal country, and coal is domestic main energy sources.Coal is in recovery process, and 70% is conny, and 30% is lump coal, and lump coal has formed 20%～30% conny again in loading and unloading roping process, not only wasted the energy but also polluted environment.So people are devoted to develop the smalls forming technique for many years always, problem such as the carbonated coal balls that existing smalls forming technique such as chemical fertilizer industry are used, humic-acid coal balls, paper pulp coal briquette, white clay coal briquette etc. all exist complex process, fixed carbon is low, cost consumption is big, thermostability can't solve.For example the making processes of carbonated coal balls is to add 20%～30% lime in coal, make moulded coal after, in carbonization in the carbonization jar more than 48 hours.Can absorb great amount of carbon dioxide in the carbonization process, influence the gas production rate of carbon monoxide, because fixed carbon has only 40%～50%, cause the situation that effect is low, labour intensity is big in the gas making process.Humic-acid coal balls, paper pulp coal briquette, white clay coal briquette etc. need oven dry in making processes, every production line drying plant is invested units up to a million, and energy consumption is very big.In chemical fertilizer industry, Industrial Boiler and civil area use, because thermostability can't solve, formed a large amount of expense hot coal end and coal ash, reversed carbon rate is up to about 30%, not only contaminate environment but also waste energy.
Three, summary of the invention:
The present invention provides a kind of forming method of clean moulded coal in order to solve the weak point in the above-mentioned background technology, and its operation is succinct convenient, the moulded coal thermostability height that adopts this method to make, active good, reversed carbon rate is low, and reduced cost, eliminated pollution environment.
For achieving the above object, the technical solution used in the present invention is:
A kind of forming method of clean moulded coal is characterized in that comprising following operation steps: add additive in the conny after pulverizing, then stirring, moulding.
The addition of above-mentioned additive can be 9～15%.
Above-mentioned additive comprises following component: kaolin, silicate, aluminate.
Above-mentioned additive also comprises following component: wilkinite, gypsum.
Above-mentioned content of additive scope can be: kaolin 20～30b, silicate 10～20b, aluminate 10～20b, wilkinite 20～30b, gypsum 1～10b (wherein b is a weight unit).
Compared with prior art, the advantage and the effect that have of the present invention is as follows:
1, the present invention adopts advanced materialization principle, and smalls is utilized, and has both greatly reduced energy consumption, and environment is effectively protected;
2, the present invention's gas production rate when chemical fertilizer industry is used is suitable with lump coal, because coal briquette is active good, gas production rate is big, so the anti-carbon of slag is no more than 8%, fixed carbon 65.46, full sulphur 0.30, ash fusion point DT ℃ 1200, and ST ℃ 1400, FT ℃, 1430, cold strength KC/ ball is greater than 100, and thermostability is more than 95%;
3, the present invention can reduce cost effectively, has created favourable condition for chemical fertilizer industry is energy-saving and cost-reducing;
4, the environmental requirement of the present invention all data fit countries in the dining room, when civil area such as dining room tea furnace uses has remarkable economic efficiency and social benefit.
Four, embodiment:
The present invention adopts a kind of coccoid additive to add in conny, can bondingly can solidify again after the adding, and the additive manufacture craft is simple and convenient, only needs a mixing and blending machine and a sack packer to get final product.The prescription of additive is: kaolin 20～30b, silicate 10～20b, aluminate 10～20b, wilkinite 20～30b, gypsum 1～10b (wherein b is a weight unit).Additive is 10～15% to the add-on of conny, and technological process is pulverizing, stirring, moulding.
Embodiment: get 25 kilograms of kaolin, 25 kilograms of silicate, 15 kilograms of aluminates, 15 kilograms of wilkinites, 5 kilograms in gypsum, after above-mentioned raw materials pulverized at normal temperatures, mix with mixing and blending machine, make the coccoid additive, join in 900 kilograms the conny, through pulverizing, stir, last moulding.The clean moulded coal of making need not be dried and airing, is not made of salt and bubble, and the finished product keeping is the same with lump coal, solidifies and can use in 48 hours.
