Problems solved by technology

However, the filtered dust cannot be effectively used and can only be buried in a centralized manner, which will also pollute the environment
In addition, when coke is produced and used, a large amount of broken coke powder will also be produced
This kind of coke powder can't be used reasonably
If it is thrown away, it will also pollute the environment and cause a waste of resources

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 [0001] The utility model relates to a molded coal with calcium carbide dust, which relates to a method for making molded coal with calcium carbide dust. Background technique [0002] In the process of producing calcium carbide, a large amount of dust will be produced, which will pollute the environment. Under the requirements of environmental protection, calcium carbide factories often use dust removal and filtration devices to filter the dust. However, the filtered dust cannot be effectively used and can only be buried in a centralized manner, which will also pollute the environment. In addition, when coke is produced and used, a large amount of broken coke powder will also be produced. This type of coke powder can not be rationally utilized. If it is thrown away, it will also pollute the environment and cause a waste of resources. Contents of the invention [0003] The purpose of the present invention is to utilize discarded calcium carbide dust and c...
