Emulsion waste oil sludge and coking system dust-removal ash briquette coal production process

Abstract

The invention relates to an emulsion waste oil sludge and coking system dust-removal ash briquette coal production process. The production process comprises the following steps: intercepting coking coal from a belt conveyor sent to a coke oven coal tower, sending 14 to 17 percent by weight of emulsion waste sludge, 16 to 20 percent of coking system dust-removal ash and 65 to 68 percent of coking coal into a primary mixing machine, then stirring, then sending the stirred material into a secondary mixing machine, sending the secondarily-stirred material into a buffer cabin by virtue of the belt conveyor, sending the material discharged from the buffer cabin into an overhead bunker through a hopper type lifter, feeding the material discharged from the overhead bunker into a quantitative feeding machine, quantitatively sending the material into a forming machine by virtue of the quantitative feeding machine, sending the formed briquette coal onto the coal tower belt conveyor by virtue of the belt conveyor, and then sending the formed briquette coal into the coal tower coke oven together with the coking coal. The production process has the advantages that the produced briquette coal is high in strength, the briquette coal can be coked normally in the coke oven, and the produced coke can be used for the production of a blast furnace; the expense for treating the waste oil sludge in an iron and steel factory can be saved, the dust-removal ash produced in a coking factory can be recycled, and an energy-saving environmental-protection purpose can be realized.

Description

technical field [0001] The invention relates to a briquette production process, in particular to a briquette production process from emulsion waste oil sludge and coking system dust removal ash. Background technique [0002] At present, iron and steel plants produce a large amount of emulsion waste oil sludge every year, and now the main treatment methods are landfill and incineration, both of which will pollute the environment. Take Taiyuan Iron and Steel Plant as an example, the emulsion waste oil sludge produced every year is handed over to the solid waste disposal center Incineration costs about 7,000 yuan per ton, and tens of millions of yuan is paid for disposal every year. This disposal method not only pollutes the environment, but also increases the burden on enterprises. Dust removal ash is the waste produced during the coking process. Due to the small particles, it is easy to cause serious pollution to the surrounding environment when the wind blows. How to ration...
