目前,世界上电炉除尘大多数是采用布袋式除尘器进行除尘,清灰方式多数采用有压力的反吹风对滤袋所挂的灰尘进行吹扫,反吹下来的粉尘落入下灰斗排出。本溪钢铁公司一钢厂新炼钢车间30t电炉除尘装置采用了某厂生产的LDF—3600型布袋除尘器,是一种下部中间进气,负压工作由微型计算机程序自(手)动控制反吹清灰的大型布袋式除尘器。捕烟装置采用全封闭中间对开式密闭罩,吸烟口设在密闭罩的顶部。共设计院作的系统设计。其系统流程图如图1所示。
At present, most of the electric furnace dust removal in the world uses a bag filter for dust removal. Most of the dust removal methods use pressure blow-back air to purge the dust hanging from the filter bag, and the dust that is blown back falls into the hopper to discharge. Benxi Iron and Steel Company, a new steel plant 30t electric furnace dust removal device using a factory production LDF-3600 bag filter, is a lower intermediate air intake, negative pressure by the microcomputer program from the (hand) Blowing dust large bag filter. Cigarette smoking device with a fully enclosed middle to open airtight hood, smoking mouth located in the top of the airtight hood. A total of design institutes for the system design. The system flow chart shown in Figure 1.
