Dedusting dry powder recycling process

Abstract

The invention relates to a dust-removal dry powder recycling process. The process procedure consists of dust-removal ash hoppers, dust powder transferring devices, exhaust collecting cavities, wet ball machines and sealed transferring devices of each dust removal points of smelters or ironworks. The process includes three steps: dusts removing-transferring, dusts collecting and wet ball transferring, i.e. a set of dust powder air-transferring device is arranged below the dust-removal ash hopper of the dust catcher; compressed air is adopted for transferring the dust through a sealed transferring device into the dust collecting cavity far away, and then a ration feeding machine is adopted for transferring the dust to the wet ball machine; after wetting and balling by the wet ball machine, the finished small balls are finally transferred to a storing bin through a sealed transferring device as recycled materials for application. The invention adopts the novel dust disposal process of dust-removal dry powders to simplify the process procedure; a sealed state is guaranteed before wetting and balling and during the transferring process so as to avoid dust rising and material scattering; the recycling treatment is simple, thus saving investigation and manpower, and being environment-protective.

Description

technical field [0001] The invention relates to raw materials in the metallurgical industry and the recovery and treatment technology of dedusted dry powder in iron and steel smelting systems, in particular to a process technology for the recovery and utilization of dedusted dry powder. Background technique [0002] At present, the raw materials in the metallurgical industry and the recycling process of dust removal and dry dust in the iron and steel smelting system adopt the following methods: [0003] 1. Use the suction tanker to suck the dedusting dry dust at each dedusting point into the tank, and then transport the tanker to the dry dust treatment site, and use the set compressed air to pump the dedusting dry powder in the tank into the dry dust bin, through It is transported to the scraper machine under the feed valve, then humidified by the humidifier, transferred by the belt conveyor, and rolled into small pellets by the cylinder mixer, and then supplied to sintering...
