Abstract | The utility model provides a system for purifying flue gas of a coke oven and capturing and recycling carbon dioxide. The system comprises a low-temperature plasma flue gas desulfurization and denitrification system, a dry quenching furnace system, a dry quenching furnace dust removal system, a waste heat recovery system, a CO2 low-temperature liquefaction system and a refrigeration system, wherein the dry quenching furnace system is used for carrying out dry quenching reaction; the dry quenching furnace dust removal system is connected with a dry quenching furnace reaction device and is used for multi-stage dust removal. After the flue gas passes through the plasma desulfurization and denitrification system, sulfur-containing and nitrogen-containing acid gases in the flue gas are removed, impurity gases in the flue gas are also greatly reduced, and preparation is made for recycling of carbon dioxide. The dry quenching furnace can react with carbon dioxide due to high temperature of red coke to generate carbo |
