Under the situation that carbon peak reaching and carbon neutralization targets are proposed in various countries in the world, the reduction of carbon dioxide emission in the industrial field is imperative. How to reduce the emission of carbon dioxide in flue gas is an important direction of continuous attention.
In the aspect of carbon emission reduction of flue gas, the common practice is to capture carbon dioxide in the flue gas by absorption or adsorption, and then transmit the carbon dioxide out for storage or utilization. The method is suitable for a thermal power plant with large installed capacity, can have scale effect to reduce carbon emission reduction cost, but the subsequent transportation and storage operation cost is still considerable, so that large-scale popularization and application are still difficult to obtain at present. The kiln which is used in a large amount in industrial enterprises is difficult to be widely applied by adopting a mode of separately carrying out trapping and utilization due to large using amount and dispersion. On one hand, because the smoke discharge amount of a large number of furnaces is not large, the furnaces are large in number and are dispersed and difficult to be intensively treated on the scale of tens of thousands of cubic meters per hour; on the other hand, since even if it is possible to capture so much carbon dioxide, its utilization is a great problem, and after all, each kiln captures a small amount of carbon dioxide and is dispersed, and the difficulty of transportation and storage is greater. In this case, it is a better choice to adopt a technology of capturing and utilizing the integrated kiln smoke to reduce carbon.
