Description
Technical field
The utility model relates to a kind of producing apparatus of moulded coal, particularly a kind of manufacturing system of coal briquette for civillan use.
Background technology
At present, in the Energy Mix of China, coal occupies very consequence.According to statistics, in China's Energy production and consumption, coal accounts for 75% left and right of total amount.But along with improving constantly of mining mechanization degree, fine coal shared ratio in raw coal is also increasing.The increase of fine coal ratio has not only reduced loose burning of coal efficient, and has seriously polluted environment.The development moulded coal is the important channel of improving fine coal utilization ratio and environmental contamination reduction.Studies show that, metallurgical, chemical industry is used, and can save lump coal or the coke of 20-40%, after Industrial Boiler, kiln use moulded coal, the loose coal of comparable burning economizes on coal 10%～27%, smoke discharge amount can reduce 50%～60%, and after adding sulphur-fixing agent, the quantity discharged of sulfurous gas can reduce 35%～50%.Therefore, the development moulded coal is of great practical significance to China.
At present, powdered coal formation divides coldmoulding and hot-forming.
Hot-forming, be generally binder free hot-forming, to adopt the method for heating to make middle aged brown coal produce certain plasticity, then extrusion forming, rapid heating is the key of powder coal hot press forming technology, in a short period of time, the fine coal under normal temperature is adopted the uprise heating unit of several groups of series connection, drying (120～150 ℃), give heat (122～250 ℃), be rapidly heated to the softening temperature interval (420～450 ℃) of coal.In fine coal moulded coal pressure ball unit, have better bonding and be the coal dust of plasticity, by tieing up warm homogenizing, extruding plasticising, fusion pressure moulding, can suppress scorching hot type piece.The type piece that not yet can harden that has just extruded from the moulded coal ball press, be admitted to the stewing tank of heat, under the condition of isolated air, slowly gradually order ground is cooling and harden into the fine and close and hard similar coke briquette of quality at this for scorching hot type piece, boil in a covered pot over a slow fire processing type piece by heat, its anti-crushing degree obviously improves, about about 2h of stewing time of heat.The similar coke briquette that adopts hot-press molding method to produce, all obviously be better than cold-pressed briquette in its cold strength, hot degree, waterproof, upgrading optimization etc. aspect many, but, the hot pressing similar coke briquette is to suppress to form under the higher rapid heating condition of temperature, and the mold temperature span of control that requires is narrower, and the operational condition in moulding process is also relatively poor, and need heat, consume energy larger, production cost is higher, should not produce civilian moulded coal cheaply.
Be suitable for the production of coal briquette for civillan use take coldmoulding as main, coldmoulding is divided into again two kinds of the molded and binder free coldmouldings of adhesive cool; Wherein binder free coldmoulding refers to use the high pressure straight forming under the prerequisite of adding additives not, namely feed coal through screening after, send into drying machine and carry out drying, after dried fine coal is cooled to 40 ℃～45 ℃, then by forming machine compression moulding.This forming method is widely used in the processing of brown coal, and is main because brown coal itself contain the cohesiveness composition, but this moulded coal manufacture method has selection to raw material, is suitable for the processing of brown coal most, can not be widely used in all raw coal.
In the situation that the binder free moulding such as bituminous coal, hard coal are comparatively difficult, the industrial adhesive cool transfer moulding method that generally adopts.Adhesive cool is molded, is with binding agent and coal particles uniform stirring, then utilizes the pattern extrusion forming, then passes through suitable aftertreatment, obtains at last satisfactory moulded coal.This method can be used for the plurality of raw materials coals such as hard coal, bituminous coal, old brown coal coke powder and blue charcoal, in view of the production cost of the molded moulded coal manufacture method of adhesive cool relatively low, widely applicable, it is long, the most most widely used forming method of present search time, at present according to China's national situation, most moulded coal factory all adopts the molded method of adhesive cool to produce moulded coal.Adding mass ratio in the fine coal of these coals is 5%～20% suitable binding agent, and by the effect of binding agent, forming pressure just can reduce to 15～50MPa, therefore in industrial easy realization.
At present, the briquette production technique that common adhesive cool is molded, comprise the techniques such as fragmentation, drying, binder formulation, stirring, moulding, oven dry aftertreatment and conveying, more common moulded coal manufacturing system is made of following equipment: the serial equipments such as crusher, drying machine, binder formulation machine, stirrer, forming machine, dryer and transfer roller, and wherein: the effect of crusher is that raw coal is crushed to required granularity; Stirrer is that coal dust and binding agent are stirred; The effect of drying machine is that mixed former moisture content of coal is remained on certain level, and is also different to the requirement of mixed former moisture content of coal according to the difference of the binding agent that uses, and for example, uses pitch as binder, and former moisture content of coal should remain on 2%～4%; Make binding agent with spent pulping liquor or humate solution, former moisture content of coal should be controlled at 10%～12%; The binder formulation machine is that the batching of binding agent is processed, more fully mixes with coal dust, and briquette binder is the key in producing, and can improve the shortcoming that hard coal hardness is large, elasticity is large and plasticity is little, makes the hot and cold intensity of moulded coal reach application requiring; Molding device is the key equipment in briquette production, and the factors such as pressure when its selection should be take the purposes of the characteristic of raw coal, moulded coal and moulding are as the basis; Drying installation after briquette molding is essential (be difficult for oven dry with briquetting before boiler except) also because moulded coal must be within a few hours substantially dry, a large amount of productions that could be continuous; Formed product after oven dry reaches certain firmness level, can discharging packing or shipment.
the molded Processes and apparatus of above-mentioned adhesive cool, generally drying machine need to be set before molding procedure, parameter characteristic according to the binding agent that adds, with coal dust with carry out drying treatment before binding agent mixes, make the moisture controlled of coal dust in certain level, could be combined with the briquette binder that adds and suppress high-intensity moulded coal, make like this manufacturing system more complicated, if the moisture controlled of raw coal is bad, the quality product of subsequent forming operation will be affected, cause ratio of briquetting low, after moulding, hardness does not reach requirement and the easy fragmentation of moulded coal etc., for intensity and the cohesiveness that increases moulded coal, reduce moulded coal broken, usually take to increase the mode of binding agent add-on, the general binding agent cost of cause is higher than coal dust, increased so again the production cost of coal briquette for civillan use, be unfavorable for applying of coal briquette for civillan use.
