Abstract
The invention relates to a coal ash type fire enhancing brick which is prepared from coal ash, coal slime, briquette coal blocks, solid fuel and coal powder. The coal ash type fire enhancing brick can improve the heat value of fuel and is good in environmental protection performance.
Description
Technical field
The application belongs to the reutilization technology field of flyash, particularly relates to a kind of flyash type very hot oven brick.
Background technology
Flyash is with coal for fuel, receives and catch the fine ash got off from flue gas, and its content accounts for the 5%～20% of coal-fired total amount, for the primary solids garbage that coal-burning power plant is got rid of.The flyash that coal-burning power plant of China discharges every year is more than 10,000,000 tons, and along with electric power industry development, flyash annual emissions increases day by day, contaminated environment, wastes resource, takies field.
At present, the technology producing moulded coal is a lot, wherein main using anthracite, mixed coal, coke powder, flyash, biological raw material (straw, sawdust etc.), furfural, gangue, coal slime etc. as primary raw material.Additionally add the auxiliary materials such as sulphur-fixing agent, waterproofing agent, consolidating agent again to produce, these methods, consume the energy too high, but heat is not high, on fire too slow during burning；Current Mainstream Packs product of coal is also had all to use coal slime, coal slime is settled out in raw coal cleaning process, containing a large amount of impurity (i.e. ash), the quality of raw coal is more low, and the heat of coal slime is more low, the impurity that coal slime contains more big (ash is more big), the product quality produced is just unstable, heat is also unstable, and the pollution of discharge is just big, and the harm of environment is still existed.
Summary of the invention
The present invention provides flyash type very hot oven brick for overcoming the technical problem existed in prior art, and this flyash type very hot oven brick can improve calorific value and the good environmental protection of fuel.
A kind of flyash type very hot oven brick, including flyash, coal slime, moulded coal block, solid fuel and coal face.
Preferably, it is also possible to include moulded coal block, solid fuel.By weight percentage, flyash accounts for 40-50%, and coal slime accounts for 20-30%, and moulded coal block accounts for 2-7%, and solid fuel accounts for 3-7%, and coal face accounts for 20-30%.
The application also provides for another flyash type very hot oven brick and manufacture method thereof for solving the problems of the prior art, and this flyash type very hot oven brick can improve calorific value and the good environmental protection of fuel.
A kind of flyash type very hot oven brick, with volume percentage, each constituent content is as follows:
Flyash and sodium bicarbonate mixture, 25-35%；
The mixture of coke blacking, manganese dioxide and potassium permanganate, 10%-15%；
Sawdust and straw mixture, 10%-15%；
Cattle manure, horsehit or the mixture of the two, 10%；
Coal flour, 5%-15%；
Coal slime and mixture of potassium nitrate, 5%-10%；
Loess and iron oxide mixture, 5%-10%；
The mixture of quick lime and Caustic soda, 5%；
Oryza glutinosa soup, 10%；
Wherein, in coke blacking, manganese dioxide and potassium permanganate mixture, the weight ratio of each composition is 5:2:3；
Wherein, sawdust and in straw mixture, the weight ratio of each composition is 2.5:1；
Wherein, in the mixture of quick lime and Caustic soda, the weight ratio of each composition is 4:1；
Wherein, flyash and in sodium bicarbonate mixture, the weight ratio of each composition is 10:1；
Wherein, loess and in iron oxide mixture, the weight ratio of each composition is 3:1；
Wherein, coal slime and in mixture of potassium nitrate, the weight ratio of each composition is 5:1；
This flyash type very hot oven brick is fabricated by by following methods, after each component Homogeneous phase mixing above-mentioned, is pressed into adobe, then adobe is immersed in antismoke agent solution after 1-3 minute, and taking-up is dried, and makes coal cinder very hot oven brick；With volume percentage, antismoke agent comprises: ethanol 25%, Polysorbate 3%, potassium chloride and ammonium nitrate mixed aqueous solution 35%, and wherein the ratio of potassium chloride, ammonium nitrate and water is 10:10:80, lime cream 35.5%, ether 1.5%；First Polysorbate, potassium chloride and ammonium nitrate mixed aqueous solution, lime cream are mixed into homogeneous latex emulsion, are subsequently adding ethanol and mix, then add diethyl ether and mix.
Containing the oxidant being provided with oxygen source in combustion-supporting agent for fuel coal, it is possible to decomposite oxygen under the high temperature conditions and promote coal fully to burn.The additionally catalyst without corrosive substance, can effectively reduce activation energy required during dissociation energy and the carbon burning of oxygen, the burning of strengthening coal, plays strongly combustion-supporting, energization, the effect of economizing on coal.Promote the burning completely of coal by adding a small amount of additive in these mixture, both can reduce unburnt heat loss, the discharge of flue dust can be reduced again.Under equal volume, the time of its burning is 1.6-2.2 times of tradition moulded coal, and its average caloic is 4590 kilocalories, about 40-50% higher than traditional moulded coal.From energy-conservation and environmental protection angle, be all of great practical significance.
Sawdust and straw are waste materials common in daily life, will result in great waste if discarded.Apply it in very hot oven brick, its ignitability can be improved.
Common antismoke agent spray often is to briquet, and the dosage that briquet absorbs antismoke agent is limited, and the present invention adopts and is directly dipped in antismoke agent by briquet, then the mode dried, and is greatly improved smoke effect.Sawdust and straw have inflammability, but smoke discharging volume is big, therefore the invention sawdust and straw are mixed in flyash, soak smoke discharging volume when will reduce said mixture burning greatly by antismoke agent, avoid the waste of sawdust and straw simultaneously, and save cost.
In order to make the briquet from powder coal ash block very hot oven brick smoke discharging volume of the present invention diminish, common antismoke agent has specially been improved by inventor, invention finds that in common antismoke agent, often mixing uses methanol and ethanol, and ethanol content is on the low side, it is unfavorable for eliminating smoke, and methanol is similar with ethanol effect in smoke elimination process, therefore specially improve the content of ethanol；In addition, common antismoke agent often uses mixed nitrate aqueous solution, inventor finds through experiment repeatedly, potassium chloride and nitrate is mixed the mixed solution that can improve smoke effect, particularly potassium chloride and ammonium nitrate greatly and makes smoke effect reach the best.
