石灰污泥共热法在水泥煅烧中的应用
Application of sludge drying heat with lime in cement burning
摘要
Abstract
This is a new way of sludge drying proposed by using waste heat from gas of clinker kiln tail, which could reduce energy consumption and realize sludge treatment. In order to simulate the productive technology of sludge dried by kiln tail gas, the sludge drying with lime was investigated in experiment. The functions of lime (CaO) during the sludge drying process were that the sludge drying rate was improved, harmful gas emission was reduced and the stability of dried sludge increased. In addition, when the amount of lime reached 10% of sludge, it was demonstrated that the sludge drying rate increased by 19. 6% at 250℃ , the a-mount of the H2S gas released was reduced by 95. 1% , the organic matter content in sewage sludge was decreased by 77. 87% .关键词
