Coking fly ash/coke powder blast furnace blowing synergy utilizing system and technology

Abstract

The invention discloses a coking fly ash / coke powder blast furnace blowing synergy utilizing system and technology. A full-sealed suction discharging tank truck transports coke powder to inlets of powder collecting bins, outlets of the powder collecting bins communicate with one ends of bin pumps through conveying pipelines correspondingly, and the other ends of the bin pumps communicate with theconveying pipelines correspondingly; the conveying pipelines of the bin pumps are connected with the top of a buffer bin or the tops of multiple buffer bins through switching valves; outlets of the buffer bins communicate with one ends of feeders through frequency conversion type soft seal cinder valves correspondingly, and the other ends of the feeders communicate with mills; and the mills communicate with a blast furnace. The technology comprises the steps that fly ash / coke powder is transported into the powder collecting bins through the full-sealed suction discharging tank truck, the cokepowder is transported into the buffer bins form the bottoms of the powder collecting bins through the bin pumps, then is discharged into the feeders by the rotation cinder valves adjustable in speed,enters the mills to be reformed and then enters the blast furnace together with coal powder, and the coke powder transferring process is completed. The energy saving and environment protection effectis achieved.

Description

technical field [0001] The invention relates to a coking dust removal ash coke powder blast furnace injection synergistic utilization system and process. Background technique [0002] With the enhancement of people's awareness of environmental protection and energy saving, enterprises are working hard to tap the potential. Waste utilization, including dust removal with high carbon content and high iron content, is returned to the blast furnace for deep utilization, and valuable things are eaten dry. Squeeze clean. However, in actual implementation, things are often contrary to expectations. Many of them use a part and sprinkle a part along the way, which seriously pollutes the environment. Some use requires more energy consumption, and some even directly affect the output of the mill. [0003] Coking ground station dedusting ash has high economic value because of its carbon content close to that of anthracite, no crystal water, uniform and small particle size. Since the am...

AI Technical Summary

Problems solved by technology

Since the amount of dust removal is hundreds of tons per day, some companies sell it cheaply as garbage, causing serious secondary pollution during transportation; some companies use it internally for digestion, but because they do not have mature technology, they basically use half Sprinkling half of it will not only cause serious secondary pollution, but also use high energy consumption, which is a negative benefit
