Description

Device for recycling carbon in flue gas

Technical Field

The utility model relates to the technical field of carbon production, in particular to a device for recycling carbon in flue gas.

Background

At present, the carbon production process is heavy, the terminal is environment-friendly, the process is pollution-free, when some carbon production enterprises produce carbon, high-heat-value tail gas is directly discharged to the atmosphere, heat energy is wasted, the atmosphere is polluted, equipment is damaged, and the production cost of the enterprises is increased. If the energy contained in the tail gas in the biomass carbonization process is recycled, the energy consumption of 12000 kilojoules can be reduced at least by one kilogram of carbon per production, the energy consumption is about equal to 0.3 DEG, and the displacement of carbon dioxide is reduced by 0.3-0.5 KG. Therefore, the flue gas is recycled, so that the air pollution is greatly reduced, the resources can be saved, the method has huge social and economic benefits and environmental benefits, the energy consumption cost of enterprises is reduced, and the production efficiency is improved.

The existing carbon recovery device for flue gas is low in carbon recovery efficiency in the flue gas, the treated flue gas still contains more carbon components, if the treated flue gas is directly discharged, resource waste can be caused, and the benefit generated by carbon recovery is low.
