Abstract
The industrial shaping coal of a kind of solid sulphur, waterproof, it is a raw material with the mixture of coal slime or coal slime and raw coal, add compound binding agent (lime and industrial table salt) and make, because adopted the compound binding agent that the source is abundant, cheap, adhesive property is good in the moulded coal, the moulded coal cost that processing is obtained is low, moulded coal cold strength height, waterproof, sulfur fixation performance are good, be easy to store and transportation,, have the extensive industrialized prospect obtaining remarkable effect aspect the saving coal minimizing environmental pollution.
Description
The present invention relates to a kind of moulded coal, particularly industrial shaping coal, gasification briquette.This moulded coal is added with compound binding agent.
The a large amount of grate firing boiler of China need use industrial shaping coal at present, owing to being becoming tight supply day of lump coal.Also be badly in need of development and be suitable for the gasification briquette that vapourizing furnace is used.But from the whole nation, the shaped coal of bituminous coal of gasification usefulness does not grow up as yet, and industrial moulded coal quantity also seldom.Industrial shaping coal has the pitch coal briquette, carbonation egg-shaped briquet, the spent pulping liquor coal briquette, the cement coal briquette, the clay coal briquette, starch coal briquette etc., these moulded coals remain in the some shortcomings part, for example: the pitch coal briquette will give out and contain carcinogenic flue gas, cause severe contamination to environment, also have any problem in the bituminous source, carbonation egg-shaped briquet is used for the water-gas generators of fertilizer plant in a large number, what this coal briquette was used is hard coal, make binding agent with lime, incorporation increases the ash oontent of moulded coal more than 20%, in addition, to do the long period with carbonated gas and handle, make its carbonating, increase process complexity; The spent pulping liquor coal briquette needs near the paper mill; The cement coal briquette is heated frangible, and hot strength is bad; Starch is made the coal briquette of caking agent, and hot strength is very poor, needs grain simultaneously.Spent pulping liquor coal briquette, clay coal briquette, its common weakness of starch coal briquette are non-moistureproof, and be easily broken, is unsuitable for transportation, and therefore, these coal briquettes are not developed always in a large number.
The object of the invention provides a kind of industrial shaping coal, this moulded coal has been owing to adopted the compound binding agent that the source is abundant, cheap, adhesive property is good, makes that to process the moulded coal cost that obtains low, and the cold strength height of moulded coal, waterproof, sulfur fixation performance are good, pollute for a short time, be easy to store and transportation.
For achieving the above object, the present invention adopts following scheme: moulded coal is a raw material with the mixture of coal slime or coal slime and raw coal, adds compound binding agent (lime and industrial table salt) and makes.
In the moulded coal consumption of compound binding agent very little, intensity is not ideal, consumption is not too economical too much, general consumption is a lime 5～8%, industrial table salt 1～2%(weight percent).Optimum amount is 7: 2.
The invention will be further described below in conjunction with embodiment:
Embodiment 1: take by weighing 91 parts of coal slimes, its moisture content is controlled at below 5%, and (consumption is 7 parts in a lime to add binding agent in coal slime, 2 parts of industrial table salts), stir uniform mixing, total moisture content of compound is controlled at 12～20%, and it is 250～300 kilograms per centimeter that the mixture that mixes is sent into pressure
2Roller briquetting machine be pressed into coal briquette (coal cinder), 45 millimeters of its diameters, high 25 millimeters, wet coal briquette under 60～70 ℃ of temperature dry 2～3 hours, under 100～120 ℃ of temperature dry 2～3 hours again, about 30 grammes per square metres in oven dry back, cold strength is 64.3 kilograms of/balls after measured, hot strength is greater than 100 kilograms of/balls, put into water through one day, one the week in addition tens days after, not brokenly do not split, after drying, recover original intensity.
Embodiment 2: the proportioning of moulded coal is a coal slime 60%, raw coal 31%, and lime 7%, industrial table salt 2%, complete processing is with embodiment 1,60 kilograms of/balls of the cold strength of moulded coal, hot strength is greater than 100 kilograms of/balls, and water resisting property is with embodiment 1.
Embodiment 3: the proportioning of moulded coal is: coal slime 31%, and raw coal 60%, lime 7%, industrial table salt 2%, complete processing is with embodiment 1,60 kilograms of/balls of cold strength, hot strength is greater than 100 kilograms of/balls, and its water resisting property is with embodiment 1.
Advantage of the present invention: owing to select the source abundant, cheap, the composite adhesive that performance is good (lime and industrial table salt), the type coal cost that processing is obtained is low, the cold strength height of type coal, waterproof, sulfur fixation performance are good, and are easy to store and transportation.
Claims (4)
