Abstract
The invention discloses a novel coal gangue combustion formula and a manufacturing process. The formula comprises the following components in parts by weight: 100 parts of coal gangue. 1-2 parts of solid alcohol, 0.5-1 part of potassium carbonate, 3-5 parts of sodium nitrite and 1-1.5 parts of potassium dichromate. The manufacturing process comprises the following steps: pulverizing the coal gangue into coal gangue blocks which are 3-5 mm in size with a pulverizer; transferring the pulverized coal gangue blocks into a horizontal chute type double-shaft stirrer; proportionally adding the solid alcohol, the potassium carbonate, the sodium nitrite and the potassium dichromate into the stirrer, and sufficiently and uniformly stirring the materials; and further adding 3-5 parts of adhesive and 3-8 parts of water into the stirrer, uniformly stirring, and manufacturing the coal gangue mixture into a hollow spherical or cylindrical finished product through a forming machine. The invention provides a revolutionary new technology which changes wastes into valuable substances, is economical and practical, cleans the environment, improves the groundwater quality, promotes the coordinated development of resources, benefits the nation and people and brings benefits to descendants. At present, all tests have been completed, and the novel coal gangue combustion formula is suitable for mass production and can be used instead of coal in industrial boilers on a large scale.
Description
Technical field:
The present invention relates to a kind ofly can make the clean-burning prescription of coal gangue and manufacturing process thereof.
Background technology:
Along with the high speed development of coal-mining industry, China's coal production last year has reached 3,500,000,000 tons, and the solid waste that coal gangue goes out of use when being coal mining and coal washing is that 10-15% of coal production calculates by coal gangue, 3.5-5 hundred million tons of annual newly-increased coal gangues.The coal gangue of bulk deposition not only takies a large amount of soils, also environment and underground water is caused serious pollution, near the quality in the farmland impact.On the other hand, global energy problem in short supply is not still effectively solved.How turning waste into wealth, developing novel economic eco-friendly power source is current urgent problem.
Summary of the invention:
The invention provides a kind of new forms of energy, a kind of New type coal spoil burning with low cost, that remove pollution is filled a prescription and manufacturing process.
Technical solution of the present invention is: a kind of New type coal spoil burning prescription in weight part, comprises 100 parts of coal gangues, 1-2 portions of solid alcohols, 0.5-1 part of salt of wormwood, 3-5 parts of Sodium Nitrites, 1-1.5 parts of potassium bichromate.
The manufacturing process of this New type coal spoil burning prescription is: the bastard coal stone that at first coal gangue is ground into 3-5mm size with pulverizer; With the coal gangue block transfer after pulverizing to hugging formula biaxial rneader; In stirrer, add solid alcohol, salt of wormwood, Sodium Nitrite, the potassium bichromate of aforementioned proportion, above-mentioned materials is stirred.Hugging formula stirrer is convenient reinforced, and Double shaft stirring makes to stir.
Be preferably in and also add 3-5 parts tackiness agent and 3-8 parts water in the stirrer, rear ball-type or the cylinder shape finished product that utilizes forming machine the coal gangue mixture to be made hollow form stirs.Product after the moulding is convenient to storage and transportation, and the type shape of hollow is conducive to the coal gangue finished product and contacts more oxygen, and it is fully burnt, and can increase calorific value simultaneously.
Get 20kg product of the present invention, the examining report that burns in boiler is:
2-3 hour combustion time;
Flame height 300-350mm;
Burner hearth core temperature 1500-1700 degree.
This shows, prescription disclosed by the invention can make low heating value coal gangue fully burn, and combustion time is long, discharges simultaneously a large amount of heat energy.The present invention is one turns waste into wealth, economical and practical, and cleaning ambient improves groundwater quality, promotes the resource coordination development, benefits the nation and the people, and is beneficial to descendants's revolutionary new technology.Present every test is finished, is suitable for batch production, and alternative coal large-scale application is in Industrial Boiler.
