Clever Carbon: Another CISDI green first - pneumatic transport system solves dusts issue at Shaogang BF7

CISDI has created another first to boost the steel sector’s pursuit of greener production methods.

It has developed a unique environmentally-friendlier solution for the transportation of dusts to a steel plant’s exterior bins.

A pneumatic transport system has been built for dusts collected from a gravity dust catcher at Baowu Shaogang’s blast furnace 7.

The Guangdong Province steelworks’ new system smoothly transports the dusts to a central bin 100 metres away.

Previously, it was believed the dusts from the gravity dust catcher were unviable for pneumatic transport because of their uneven granular sizes and large weights, which ranged from 1.6 to 1.8 tonnes per cubic metre.

A suction/exhaust tank car or truck was used to transport them to an outside bin. But this method was prone to releasing flying dusts into the atmosphere. It also took up a huge amount of energy and was a laborious task.

CISDI’s team carried out a specialist study and spent over a year to design, optimise, commission and operate the solution - a pneumatic transport system.

Dusts are now transported in an enclosed working environment and there is no risk of flying dust when the dusts are loaded into the car.

CISDI’s solution has achieved:

² Fully automatic operation

² Intelligent judgment of abnormities and alarm-raising

² Automatic correction without any external/manual interference

² All-weather monitoring of gravity dust catcher system

² Timely resolution of dust accumulation.

Efficient, green smelting: Shaogang blast furnace 7 is operating with CISDI’s innovative dust transport system
