Abstract

The invention relates to the field of energy saving and environment protection, and relates to the circulation utilization of CO2 (carbon dioxide) and O2 (oxygen gas), in particular to a power plant carbon and oxygen circulation utilization device and a process of the device. The power plant carbon and oxygen circulation utilization device comprises a coal conveyor (17), a CO2 back flow device (6), a plasma torch catalyst (1), an energy-saving boiler (2), a heat exchanger (3), a CO2 catching separator (12), a deaerator (14), a remote anti-explosion total control detection system (18) and a chimney (13). A carrier air coal conveying mode is adopted for conveying reaction raw materials into the plasma torch catalyst (1) to be catalyzed, the catalyzed reaction substances are conveyed into the energy-saving boiler (2) to realize the sufficient combustion with O2, and the generated CO2 is cyclically utilized after the deoxygenation. The device and the process have the advantages that firstly, the low-cost pure oxygen combustion is realized; secondly, the CO2 backflow catalysis and deoxygenation circulation utilization is realized; thirdly, the equipment investment is reduced, and 70 to 80 percent of the equipment volume of the boilers in links of dust removal, denitration, desulfuration and the like is reduced; fourthly, 45 to 70 percent of the coal consumption is saved; and fifthly, the pure conversion rate of heat energy is improved by more than one time.

Description

technical field [0001] The invention relates to the field of energy conservation and environmental protection, and to the recycling of CO2 and O2, in particular to a carbon-oxygen recycling device and a process for a power plant. Background technique [0002] CO2, the main culprit of the greenhouse effect generated by power plants, is not conducive to the current environmental protection requirements. At the same time, the current traditional power plant technology has the following defects in addition to IGCC power generation: [0003] 1. Air combustion, the net conversion rate of heat energy is low, the main reaction formula is: C+O2+N2——CO2+N2; [0004] About 2.7 tons of O2 are needed to burn 1 ton of standard coal, and about 10 tons of N2 are brought in. In the combustion exhaust gas, the content of N2 is 78-85%, and the content of CO2 is only 8-15%. The high content of N2 in the flue gas is the direct cause of the low net conversion rate of heat energy, and the second ...
