Abstract
The invention relates to novel high-energy coal dust and a preparation method thereof. The novel coal dust comprises common coal dust, nitroglycerin or trinitrotoluene (TNT), and a surfactant which are uniformly distributed in the common coal dust. The combustion heat value of the novel coal dust is increased greatly, the complete combustion of the coal dust is facilitated, the coal resources can be saved, and pollution and coal waste caused by incomplete combustion are reduced; by the preparation method of the novel coal dust, the nitroglycerin or TNT powder, and methanol or ethanol, the surfactant, and water are mixed to form emulsion; the nitroglycerin or TNT in the emulsion are extremely tiny particles; when the emulsion is sprayed in the coal dust, the nitroglycerin or TNT can be permeated into the coal dust, the safety in the storage, transportation and using processes is high, the nitroglycerin or TNT and the coal dust are mixed more uniformly, and the utilization rate of the nitroglycerin or the TNT can be improved; and due to the application of the surfactant, the emulsion is more uniform, and sedimentation is avoided.
Description
Technical field
The present invention relates to the novel energy field, especially a kind of new coal powder and manufacture method thereof with higher fuel value.
Background technology
As a kind of traditional energy, coal is widely used in every field, for example boiler, industrial furnace, generating etc.But existing coal combustion process is the common coal of directly burning, and coal resources are Nonrenewable resources, in present consumption, the coal resources that can supply to exploit in the near future can be exhausted, so, the bigger new coal powder of heat that provides a kind of back of burning to discharge is provided.
Summary of the invention
At the deficiency of above existing burning with coal, the purpose of this invention is to provide a kind of new coal powder with higher combustion heat value, and the method for making described new coal powder.
The objective of the invention is by realizing by the following technical solutions: a kind of high-octane new coal powder, it comprises common coal dust, be uniformly distributed in nitroglycerine in the common coal dust or TNT, tensio-active agent.
As optimized technical scheme of the present invention, in the new coal powder, the mass percent of nitroglycerine or TNT is 5-15%, and the mass percent of common coal dust is 85-95%, and the mass percent of tensio-active agent is 1-5%.
A kind of method of making new coal powder of the present invention, it may further comprise the steps:
The first step: provide the nitroglycerine of a coal yard that stores common coal, conveying flat rubber belting that a coal pulverizer, is used for pulverized coal conveying, formula ratio or TNT powder, with the mass ratio of nitroglycerine or TNT be tensio-active agent and the some water and an atomizer of the methyl alcohol of 1:1-1:2 or ethanol, formula ratio;
Second step: the common coal that takes by weighing formula ratio is inserted coal pulverizer, and coal pulverizer is with the coal grind into powder; Simultaneously, nitroglycerine in the first step or TNT powder are added in methyl alcohol or the ethanol, stir, make nitroglycerine or TNT powder be dissolved in methyl alcohol or ethanol, in gained solution, add the tensio-active agent in the first step, stir, stir to the water that wherein adds the first step again, obtain uniform nitroglycerine or TNT emulsion, this emulsion is injected atomizer;
The 3rd step: the second step gained coal dust is positioned on the conveying flat rubber belting that transmission, emulsion wherein evenly is sprayed in the coal dust of carrying on the flat rubber belting with atomizer;
The 4th step: continue the drive transfer flat rubber belting, the 3rd step gained is sprayed has the coal dust of nitroglycerine or TNT emulsion to be delivered to the new coal powder field, makes its natural air drying, methyl alcohol or ethanol volatilization, water evaporation.
With respect to prior art, new coal powder combustion heat value of the present invention is significantly increased, and combustion heat value increases the perfect combustion also help coal dust, can save coal resources, reduces to pollute and coal waste that incomplete combustion causes; The manufacture method of new coal powder of the present invention is the purpose that nitroglycerine or TNT powder and methyl alcohol or ethanol, tensio-active agent and water are mixed into emulsion, nitroglycerine in the emulsion or TNT are atomic little particulate state, emulsion is sprayed in the coal dust, nitroglycerine or TNT can infiltrate to coal dust inside, security is higher in storage, transportation and the use, and nitroglycerine or TNT are more even with mixing of coal dust, can improve the utilization ratio of nitroglycerine or TNT; The application of tensio-active agent makes emulsion more even, avoids deposition.
Embodiment
The high-octane new coal powder of first kind of embodiment of the present invention comprises common coal dust, is uniformly distributed in nitroglycerine or TNT emulsified particle and tensio-active agent in the common coal dust.In the new coal powder, the mass percent of nitroglycerine or TNT is 5-15%, and the mass percent of common coal dust is 85-95%, and the mass percent of tensio-active agent is 1-5%.
The preparation method of present embodiment new coal powder may further comprise the steps:
The first step: provide a coal yard that stores common coal, conveying flat rubber belting that a coal pulverizer, is used for pulverized coal conveying, formula ratio nitroglycerine, with the mass ratio of nitroglycerine be the methyl alcohol of 1:1-1:2, tensio-active agent and the some water and an atomizer of formula ratio;
Second step: the common coal that takes by weighing formula ratio is inserted coal pulverizer, and coal pulverizer is with the coal grind into powder; Simultaneously, nitroglycerine in the first step is added in the methyl alcohol, stir, make nitroglycerine be dissolved in methyl alcohol, again the tensio-active agent in the first step is added in the methyl alcohol, stir, make nitroglycerine be dissolved in methyl alcohol more full and uniformly, stir to the water that wherein adds the first step again, obtain uniform nitroglycerine emulsion, this emulsion is injected atomizer;
The 3rd step: the second step gained coal dust is positioned on the conveying flat rubber belting that transmission, emulsion wherein evenly is sprayed in the coal dust of carrying on the flat rubber belting with atomizer;
The 4th step: continue the drive transfer flat rubber belting, the coal dust that the 3rd step gained is sprayed the emulsion that nitroglycerine and methyl alcohol are arranged is delivered to the new coal powder field, makes its natural air drying, and the present invention's new coal powder is promptly made in the evaporation of first alcohol and water.
Among the preparation method of above-mentioned new coal powder, nitroglycerine can be substituted by TNT, and methyl alcohol also can be substituted by ethanol.
Nitroglycerine or TNT are dissolved in methyl alcohol or ethanol to be made the purpose of emulsion and is: through spraying, nitroglycerine in the emulsion or TNT infiltrate to coal dust with trickleer particle, coal dust fully absorbs it, nitroglycerine and TNT can not become cluster, avoid blasting, and can improve the utilization ratio of nitroglycerine or TNT.
Because the burning of coal calorific value is 21MJ/kg, and the combustion heat value of nitroglycerine is 544 MJ/kg, the combustion heat value of TNT is 420MJ/kg, so having added the new coal powder combustion heat value that nitroglycerine or TNT form in the common coal dust is significantly increased, and combustion heat value increases the perfect combustion that also helps coal dust, can save coal resources, reduce to pollute and coal waste that incomplete combustion causes.
On the other hand, after nitroglycerine or the TNT burning, its product is a small amount of carbon monoxide, nitrogen protoxide, nitrogen peroxide and great amount of carbon dioxide, water, identical with the product behind the common coal dust firing, so, can not cause extra pollution after having added the new coal powder burning of nitroglycerine or TNT to environment.
