Blast furnace fly ash treatment device and using method thereof

Abstract

The invention relates to the technical field of blast furnace fly ash treatment, in particular to a blast furnace fly ash treatment device and a using method thereof. The blast furnace fly ash treatment device comprises feeding mechanisms, two storage mechanisms, a discharging mechanism and a grinding mechanism. The two oppositely-arranged feeding mechanisms achieve automatic feeding of coke powder and dusting powder at the same time, the storage mechanisms arranged on the surfaces of the two feeding mechanisms realize storage of the coke powder and dusting powder and facilitate feeding of the feeding mechanisms, and when the feeding mechanisms rotate, the storage mechanisms are shaken to facilitate feeding. The two feeding mechanisms extend into the discharging mechanism, mixing of coke powder and dusting powder is achieved, timed feeding is achieved when one ends of the feeding mechanisms rotate, and the operation is easy. The interiors of the feeding mechanisms are connected with the grinding mechanism for grinding coke powder and dusting powder, particles are ground when one end of the discharging mechanism rotates, and comprehensive mixing of the coke powder and the dusting powder is facilitated.

Description

technical field [0001] The invention relates to the technical field of blast furnace dust removal and ash treatment, in particular to a blast furnace dust removal and ash treatment device and a method for using the same. Background technique [0002] Dust removal ash can be roughly divided into two categories according to the needs and properties of dust removal settings: flue gas dust removal ash and environmental dust removal ash. Flue gas dust removal is necessary in the production process, such as high temperature flue gas of sintering head, dust removal of blast furnace and converter gas system. This kind of dust removal dust is flue gas dust removal dust. And other dust removal equipment, most of the fly ash collected from the particulate waste gas, its composition is related to the collected particulate gas, iron and steel enterprises will produce a large amount of dust, iron oxide scale, etc., generally have a good use value. [0003] However, when the current dust ...

AI Technical Summary

Problems solved by technology

[0003] However, when the current dust removal ash is processed, the dust removal powder and coke powder must be mixed first. When mixing, the dust removal powder and coke powder are directly added to the inside of the rotary kiln. It is difficult to control the time of feeding, and they are directly added to the rotary kiln. It is difficult to add the internal dedusting powder and coke powder regularly, which causes uneven heating of the coke powder and dedusting powder in the rotary kiln, and the coke powder and dedusting powder directly added to the interior of the rotary kiln have granular coke powder and dedusting powder before adding The dust removal powder is not crushed when it is added to the inside of the rotary kiln, and it is difficult to fully mix the granular coke powder and the dust removal powder when the rotary kiln is turned over, which affects the treatment effect of the dust removal powder
