Abstract

The present invention is environment friendly blast furnace slag treating process and system. The blast furnace slag treating process includes water quenching the red slag for fast cooling with the granulating tank sprayed cooling water and collecting in the collecting pipeline; conveying to the distributor of dewatering drum and separating into water granulated slag falling to the belt conveyer for being transported to the slag yard and filtered hot water; collecting hot water, pumping to cooling tower for cooling and condensing through the atomizing nozzle in the condensing tower; and collecting the condensated water and returning through the third water pipe, the buffering tank and the fourth water pipe to the granulating tank for reuse. The present invention has the advantages of simple system composition, environment friendship, low power consumption, etc.

Description

technical field

[0001] The invention belongs to the field of metallurgical ironmaking equipment, and in particular relates to a blast furnace slag treatment process and a system thereof. Background technique

[0002] At present, the domestic environment-friendly blast furnace slag treatment system mainly consists of red slag ditch, granulation box, granulation tank (pool), dehydration drum, steam condensation recovery system (condensation tower), water pump, cooling tower, granulation condensation circulation water pipe The red slag ditch contains molten slag, the output end of the red slag ditch is located above the input end of the granulation tank (pool), and a granulation box is arranged between the output end of the red slag ditch and the input end of the granulation tank. There is a spray hole on the granulation box. When the slag from the red slag ditch falls into the granulation tank, the high-pressure water in the granulation box is sprayed out through the water spr...
