Abstract

The invention relates to a device and method for glass granulation and waste heat recovery of molten smelting slag. The device comprises a chute (1), a tundish (2), a flow guide groove (3), a granulating chamber (4), a granulating fan (5), a blast groove (6), a tubular heat exchanger (8), a cooling fan (9), a spiral discharge device (10), a lifter, preferably a bucket lifter (11), a finished product bin (12), a platy heat exchanger (14), a first steam pipe (15), a second steam pipe (15), a power generator set (16) and a purifying and discharging apparatus. The molten smelting slag is convertedinto vitreous particles through the device in order to facilitate resource utilization; meanwhile, waste heat recovery is carried out, maximum recovery of molten smelting slag resources is realized,and the high-efficiency, well-equipped, automated, harmless and resourceful treatment of the molten smelting slag is achieved, and ultra-low emission is realized in the treatment process; the device has an outstanding process and the advantage of being environmentally friendly.

Description

technical field [0001] The invention relates to a device and method for glass granulation and waste heat recovery of molten smelting slag, in particular to a device and method for efficiently converting high-temperature liquid smelting slag into glass for granulation and recovering waste heat. Background technique [0002] my country is a big industrial country with many high-temperature smelting enterprises in steel and non-ferrous metals, and the output of major metals is basically more than 50% of the world's. Accompanied by a large amount of metal production, a large amount of high-temperature smelting slag is produced, such as blast furnace slag, steel slag, copper slag, nickel slag and other bulk molten smelting slag. At present, the resource utilization rate of smelting slag in my country is low, and the resource utilization rate is less than half. There are still a large amount of waste slag piled up, occupying a large amount of land, and there are major environmenta...
