Pneumatic conveying and blast furnace injecting device for coke oven dust-removing ash and using method thereof

Abstract

The invention discloses a pneumatic conveying and blast furnace injecting device for coke oven dust-removing ash and a using method of the device. The pneumatic conveying and blast furnace injecting device comprises a coke oven dust-removing ash pneumatic conveying air source unit, a coke oven dust-removing ash pneumatic conveying main unit, a gas-pressure balance unit, an ash conveying pipeline travel cleaning unit, a coke oven dust-removing ash and secondary coal distribution unit, a coke oven dust-removing ash and secondary coal grinding unit, a coke oven dust-removing ash and secondary coal grinded material collection unit, a pulverized coal baking unit, a coke oven dust-removing ash and secondary coal grinding process safe-extinguishment unit and a blast furnace injecting unit. The device completely solves the problem that coke oven dust-removing ash is used as one of the biggest coked environmental pollution sources by long-distance sealed pneumatic conveying, is safe and reliable in operation, improves the environmental protection benefit, the energy efficiency and the automatic production level, achieves full-automatic production operation, reduces the labour intensity of a worker and achieves the production management idea based on humanistic theory.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a pneumatic conveying and blast furnace blowing device for coke oven dedusting and a method for using the same. Background technique [0002] With the control of dust emission in the coke oven production process and the popularization and application of CDQ technology, the coking industry can collect a large amount of coke oven dust every day, and the collected coke oven dust is mainly composed of coke powder, containing carbon The amount is above 85%. How to do a good job in the environmental protection transportation and effective comprehensive utilization of coke oven dust removal is a problem worth studying. [0003] At present, the traditional treatment method of domestic coke oven dust removal is to use humidification and transport it to the sintering yard by tank truck for use in the sintering process. The traditional method has the following problems: the process of vehicle loa...
