Method for treating exhaust gas from cement manufacturing equipment |
摘要 |
An exhaust gas treatment method including: (A) a step of treating exhaust gas from cement manufacturing equipment by using a dust collector (9) to collect dust containing chlorinated organic compounds, and discharging the exhaust gas after the treatment by the dust collector (9), and (B) a step of charging all or part of the dust collected by the dust collector (9) into a place (e.g. a rotary kiln (5), a pre-calciner (6), and a cyclone (4d) having a temperature of at least 800°C inside the cement manufacturing equipment. The remainder of the dust from step (B) may be charged into a place (e.g. a raw material supply passage (3) having a temperature below 800°C inside the cement manufacturing equipment, provided the amount of the remainder to be charged is smaller than a certain amount. Chlorinated organic compounds such as dioxins in the exhaust gas can be decomposed efficiently to be made harmless, merely by including simple and low-cost means (e.g. a dust feeding means (12), etc.). |
