Study on Treating Sintering Flue Gas with Coking Wastewater

Abstract:

There are large amount of ammonia in coking wastewater. It is a good recycling desulfurizer. Sintering flue gas has the characteristics, such as large amount of, low SO₂concentration, great changes of operation load. Treating sintering flue gas with coking wastewater can attain the destination of treating waste with waste. This paper adopts a spray tower countercurrent device, and SO₂ concentration in the entrance and exit flue gas is on line detected by an automatic flue gas detection instrument. The paper studies on the change rule of SO₂concentration in the process of treating sintering flue gas using coking wastewater, and the influence of SO₂ initial concentration in sintering flue gas to the desulfurization rate. The results show that after being treated the sintering flue gas can reach the emission standard for air pollutants of iron and steel industry.
