METHOD FOR CLEANING BYPASS GASES OF THE CEMENT OR MINERAL INDUSTRY, AND SYSTEM OF THE CEMENT OR MINERAL INDUSTRY |
摘要 |
A method for cleaning bypass gases of the cement or mineral industry includes cooling down a removed bypass gas from a cement or mineral processing plant to a temperature of between 500° C. and 150° C., and coarsely dedusting the bypass gas, the dust burden being reduced by 30 to 95%. After the dedusting step, the gaseous constituents contained in the partly dedusted bypass gas are reduced in a reducing step. The partly dedusted bypass gas is further finely dedusted. The gaseous constituents reducing step includes at least a catalytic reduction of one or more of nitrogen oxides, hydrocarbons, and carbon monoxide. |

1. A method for cleaning bypass gases of the cement or mineral industry comprising:
cooling down a removed bypass gas from a cement or mineral processing plant to a temperature of between 500° C. and 150° C.; coarsely dedusting the bypass gas, the dust burden being reduced by between 30% and 95%; reducing gaseous constituents contained in the partly dedusted bypass gas by at least catalytically reducing one or more of nitrogen oxides, hydrocarbons, and carbon monoxide; and finely dedusting the bypass gas. |
