Abstract

The invention belongs to the technical field of dust removal, and in particular relates to a dust treatment system and process in storage and transportation of binders for pellet production. The dusttreatment system is characterized by comprising an air inlet duct connected with a dust collecting hood arranged at dust generating points in the storage and transportation process of the binders, a centrifugal fan connected with the air inlet duct, a heater connected with the centrifugal fan, a drum dryer connected with the heater and an exhaust duct connected with the drum dryer, and the exhaustduct is connected with a main pipe of a bag dust collector. The dust treatment system and process in the storage and transportation of the binders for the pellet production disclosed by the inventionavoids the complicated process of performing dust treatment by requiring to separately arrange the centrifugal fan, the bag dust collector and a dust removal, collection and return device and only requires to blow dust into the drum dryer through the fan, iron concentrate containing certain moisture can absorb the dust to reduce moisture of materials, avoid the waste of the binders and reduce thenumber of the fans. The dust treatment system is simple in process structure and the dust treatment process is easy in implementation.

Description

technical field [0001] The invention belongs to the technical field of dust removal, and in particular relates to a dust treatment system and process for storing and transporting a binder for pellet production. Background technique [0002] There are strict requirements on the content of iron ore in the production of pellets, and the moisture is generally controlled at 6% to 11%, while the iron concentrate powder produced by the concentrator has a relatively high moisture content, generally 9% to 11%, so an additional drying operation is required . The most used equipment for drying operations is the drum dryer. The iron powder with high water content is fed into the drum dryer, and the hot air heated by the heater is blown into the drum dryer by using a centrifugal separator to take away a certain amount of water. Dry fine powder for pelleting operation. A certain amount of additives need to be mixed in the pelleting process to improve its physical and chemical properties,...
