The course of work of the present invention and operation principle:
Raw material is coal dust, broken coke, coal slime, and at first raw material being carried out Mechanical Crushing is coal dust, uses forcing press compression moulding then.This production method is simple, and product has intensity height, advantage such as cheap, is the desirable substitute products of natural lump coal, can be widely used in resident living with coal and industrial production coal.
Granulation flow system of the present invention: raw coal is a duff through shaker vibration sieve Xian earlier; Add in the duff and flow agent, binding agent and water admittedly after mixing stirring, enter the comminutor granulation, after pushing, be finished product again.
(1) coal divides screen system
Raw coal just enters the one-level vibratory sieve from harbour handling disembarkation and sieves, and one-level vibratory sieve mesh is 12-13mm, mainly is to guarantee screening fully, and the free surface moisture of coal requires≤8%, otherwise crosses wet can't the screening.Near duff is stacked under the sieve, enter the secondary vibration sieve of mesh 6mm during manufacturing again, the duff particle diameter≤4mm under the sieve is as the raw material of solid sulphur formed coal.Isolated lump coal can mix the back with solid sulphur formed coal to be used.The ratio of duff is roughly 40-50% after sieving.
(2) coal, sulphur-fixing agent, binding agent proportioning are mixed
The additional proportion of sulphur-fixing agent and binding agent is the key of solid sulphur formed coal success, and the former influences captured sulfur result, and the latter determines briquette strength.Consider the lump coal multifuel combustion that solid sulphur formed coal will come out with sub-sieve, the sulfur-bearing in the lump coal also will be included, thus sulphur-fixing agent with addition of the time calcium oxide addition to increase in proportion.
The binding agent kind is more, and the binding agent addition is decided with the kind of raw coal, and the caking property of coal that calorific value is low, ash is high is good, can lack adding additives, too much can reduce the calorific value of solid sulphur formed coal, increases ash, the influence burning.
(3) mixing of coal charge and humidification
Mix through the mixer stirring by humidification, sulphur-fixing agent, binding agent, water, coal dust are mixed.The humidity that mixes the back coal charge is very important, and too the wet type coal particle does not have intensity, and too dried granulation machine orifice plate can stop up, and generally is controlled at the outer moisture content 10% of compound and is advisable.Can control humidity by regulating discharge in the production.
(4) moulding
Owing to adopted the granulation mode that edging is pressed of grinding, material is extruded fast by the moulding hole in the template under the brute force extruding, is delivered to rickyard after the process batch mixing pan throws away conveying equipment; Rotate lower part kinetic energy in high speed simultaneously and change into heat energy, the solid sulphur formed coal of producing is higher than environment temperature, have certain wet strength and good moisture evaporation, so needn't carry out heating, drying to product, as long as be placed under the coal canopy natural air drying 0.5-1 days, can reach the working strength requirement.Can place the outfield winter and dry or utilize heater oven dry, intensity is better like this, and its granule strength can reach 30～50N/ grain.
