Abstract
A combustion promoting powder for civil or industrial briquette is prepared from oil-containing mud from oil field (60-80%) and at least one of calcium lime (10-20%), powdered coal ash (10-30%) and furaldehyde (10-30%) through proportional mixing, crushing and loading into bags, and features use of wastes and reducing cost by 20-30%.
Description
The present invention relates to a kind of moulded coal combustion supporting powder compound method and technology that is used to make civilian or industrial shaping coal.
At present, the civilian or industrial shaping coal of China all contains more high-quality coal, though have advantages such as easy firing, environmental pollution are little, because it is processed the high-quality coal, cost is higher, does not also have large-scale popularization to use in China.At the problems referred to above, study more to civilian or industrial shaping coal both at home and abroad, starting point is and reduces fat coal content, but problems such as the moulded coal calorific value is low, nonflammable have been caused, be head it off, have in moulded coal batching, add certain chemical compound or heavy oil, but this makes again the moulded coal cost increase, even cost is also high when not reducing fat coal content.
Task of the present invention is to provide a kind of moulded coal combustion supporting powder compound method and technology, the moulded coal combustion supporting powder that adopts this method and technology to make, with oil field refuse oily sludge is main raw material, uses when this combustion supporting powder is made moulded coal and can reduce the fat coal carbon content greatly, thereby reduce cost.
For realizing above-mentioned task, (main component is mud, crude oil, moisture and a small amount of other foreign material with oil field oil-containing mud in the present invention, wherein between the crude content about 8～40%, average 15 left and right sides %) be main raw material, cooperate in other material such as unslaked lime, flyash, the furfural at least aly, make the moulded coal combustion supporting powder.Wherein: at least a in oily sludge 60～80% unslaked limes 10%～20%, flyash 10%～30%, the furfural 10%～30% (when selecting for use when two or more, its total content is 20%～40%).
The technology of compound method decision is as follows according to the present invention: by each substances content batching in the compound method, after stirring with stirrer, send in the standing crusher broken, in the bag of packing into finished product.
The present invention is simple, utilize it can effectively utilize oil field refuse oily sludge, the environmental pollution of having avoided the long-term air storage of mud to cause, the combustion supporting powder of making is used to make moulded coal can reduce fat coal content, can utilize power plant's waste material flyash and the little low grade coal of purposes again, help environmental protection, can reduce moulded coal cost 20～30% again, have favorable economic benefit, but large-scale popularization is used.
Embodiment 1: get oily sludge 80%, unslaked lime 20% is made the moulded coal combustion supporting powder by technology of the present invention, and its ash content is 47.07%, volatile matter 27.70%, thermal value 11.257MJ/kg.
Embodiment 2: get oily sludge 80%, flyash 20% is made the moulded coal combustion supporting powder by technology of the present invention, and its ash content is 49.15%, volatile matter 19.48%, thermal value 11.249MJ/kg.
Embodiment 3: get oily sludge 60%, and flyash 30%, unslaked lime 10% is made the moulded coal combustion supporting powder by technology of the present invention, and its ash content is 53.44%, volatile matter 17.0%, thermal value 9.785MJ/kg.
Embodiment 4: get oily sludge 60%, and unslaked lime 10%, furfural 30% is made the moulded coal combustion supporting powder by technology of the present invention, and its ash content is 30.24%, volatile matter 36.44%, thermal value 15.447MJ/kg.
Embodiment 5: get oily sludge 60%, and unslaked lime 10%, furfural 10%, flyash 20% is made the moulded coal combustion supporting powder by technology of the present invention, and its ash content is 40.14%, volatile matter 34.23%, thermal value 13.430MJ/kg.
Claims (2)
1, a kind of moulded coal combustion supporting powder compound method that is used to make civilian or industrial shaping coal, it is characterized in that this invention is by oil field oil-containing mud 60～80%, and at least a in the unslaked lime 10%～20%, flyash 10%～30%, furfural 10%～30% (when selecting for use when two or more, its total content is 20%～40%) formed.
2, a kind of moulded coal combustion supporting powder blending process that is used to make civilian or industrial shaping coal is characterized in that: earlier by each substances content batching in the compound method, after stirring with stirrer, send in the standing crusher broken, in the bag of packing into finished product.
