Abstract
The invention discloses calcium carbide dust briquette and relates to a method for producing briquettes through using calcium carbide dust. The composition of the calcium carbide dust briquette is formed by calcium carbide dust and coke powder, wherein, the volume percentage of the calcium carbide dust is between 50 and 70 percent, the volume percentage of the coke powder is between 50 and 30 percent; during the production, the water with 25 to 35 percent of the total volume of the calcium carbide dust and the coke powder is fully mixed with the calcium carbide dust, then is placed for a period of time to ensure that the gas produced by the water and calcium carbide is completely discharged, and then is added with the coke powder to evenly mix to make a compression molding to dry. The test shows that the average heat calorie of the briquette is 3786 kilocalories which are 30 to 40 percent higher than the prior briquette. The combustion time of the briquette doubles the prior briquette with the same volume. In addition, the calcium carbide dust briquette is waterproof and not afraid of weather exposure, and has no smoke during the combustion and low sulfur content. More importantly, the calcium carbide dust briquette solves the pollution problem caused by the calcium carbide dust to the environment.
Description
Technical field
A kind of calcium carbide dust molded coal relates to a kind of method of utilizing calcium carbide dust to make moulded coal.
Background technology
In the process of producing calcium carbide, can produce a large amount of dust environment is polluted.Under requirement on environmental protection, calcium carbide factory adopts dedusting filter that dust-filtering is got off more.But the dust that filters can't effectively utilize, and can only concentrate landfill, can pollute environment equally.In addition, when producing and use coke, also can produce a large amount of broken coke ends.This class coke end also can't reasonable use.If throw away, also can pollute environment, cause the waste of resource simultaneously.
Summary of the invention
The objective of the invention is to utilize depleted calcium carbide dust and coke ultimogeniture to produce moulded coal.
The composition of this calcium carbide dust molded coal is made of calcium carbide dust and coke end; Wherein the volume percent of calcium carbide dust is 50-70%, and the volume percent at coke end is 50-30%; During making, behind the water and calcium carbide dust thorough mixing with the 25-35% of calcium carbide dust and coke end cumulative volume, place for some time, the gas of water and calcium carbide generation is discharged fully after, adding coke end mixes, compression moulding gets final product behind the airing.
This calcium carbide dust molded coal is through test, and its average caloic is 3786 kilocalories.Than the high about 30-40% of traditional moulded coal.Under equal volume, be the twice of traditional moulded coal its combustion time.In addition, this calcium carbide dust molded coal waterproof is not afraid of weathering, and smokeless during burning, sulphur content is low.The more important thing is that it has solved calcium carbide dust pollution on the environment problem.
Embodiment
Embodiment 1:
65 cubic metres of power taking stone flour dirt add 35 cubic metres water, stir, and place 2-5 hour, make power and water stone flour dirt mix the gas that the back produces and discharge, and add 35 cubic metres of coke ends, and compression moulding after stirring gets final product behind the airing.
Embodiment 2:
60 cubic metres of power taking stone flour dirt add 30 cubic metres water, stir, and place 2-5 hour, make power and water stone flour dirt mix the gas that the back produces and discharge, and add 40 cubic metres of coke ends, and compression moulding after stirring gets final product behind the airing.
Embodiment 3:
50 cubic metres of power taking stone flour dirt add 25 cubic metres water, stir, and place 2-5 hour, make power and water stone flour dirt mix the gas that the back produces and discharge, and add 50 cubic metres of coke ends, and compression moulding after stirring gets final product behind the airing.
Claims (1)
