Abstract

The invention discloses a sintering cooling waste gas zero emission system and a sintering cooling process. The sintering cooling waste gas zero emission system comprises a pre-cooling device, an annular cooler, a dust removal device, an exhaust fan, a waste heat boiler, a control unit and a temperature detection unit, wherein the pre-cooling device is arranged on a hot sintered ore falling path between the discharging end of a crusher corresponding to a sintering machine and the feeding end of a circular cooler, a hot ore inlet is formed in the position, facing the discharging end of the crusher, of the upper end surface of the pre-cooling device, a hot ore outlet is formed in the position, facing the feeding end of the circular cooler, of the lower end face of the pre-cooling device, the pre-cooling device further comprises a hot air outlet, and the hot air outlet is led to the air inlet end of the waste heat boiler through the dust removal device and the exhaust fan in sequence. The sintering cooling waste gas zero emission system aims at solving the technical problem that in the sintering process in the prior art, more cooling waste gas is emitted.

Description

technical field [0001] The invention relates to the technical field of sintering technology, in particular to a sintering cooling waste gas zero emission system and a sintering cooling process. Background technique [0002] The iron and steel industry is the foundation and pillar industry of my country's national economy. my country's iron and steel smelting is dominated by the long process of "sintering (pellet) coking-blast furnace-converter". More than 75% of the blast furnace charge comes from sintering ore, and the sintering process is steel In the high energy consumption and high pollution concentrated link in the process, the energy consumption accounts for 10% of the total energy consumption of iron and steel metallurgy, and the exhaust gas emission accounts for 50% of the total exhaust gas volume of the iron and steel industry. Micron-sized fine particle dust, SOx, NOx, persistent The emission of pollutants such as organic matter and heavy metals ranks first in the ir...
