污泥干化过程中含硫气体的抑制研究
Control of Sulfur-containing Gas During Drying of Sludge
摘要
Abstract
To reduce the emission of the sulfur-containing gas during drying of sludge and develop new type of drying technology, this paper studies the factors such as the temperature,time on the influence the release of the sulfurous gas and put forward the process and parameter to control the release the carbon disulfide, hydrogen sulfide and sulfur dioxide:reducing the drying temperature,shorting the drying time and adding calcium oxide all can control the release of the carbon disulfide, hydrogen sulfide and sulfur dioxide effectively.Control the drying temperature below 250 ℃and drying time within 30 s.When the proportion of sludge and calcium oxide is 1∶1, the rate of inhibition for the gas is close to one hundred percent.关键词
