Abstract

The invention relates to a method and device for treating nitrous oxide tail gas by using a fuel cell. The device comprises a solid oxide fuel cell, and the structure of the solid oxide fuel cell comprises a shell, a fuel cell tube and a cathode bed material; a cathode gas inlet and a cathode gas outlet are formed in the shell, and cathode gas comprises nitrous oxide to be treated; at least one fuel cell tube is arranged in the shell, a cavity is formed between the inner wall of the shell and the outer wall of the cathode of the at least one fuel cell tube, and the cathode bed material is packed in the cavity; an air distribution plate is arranged in the shell, and cathode gas flows in from the cathode gas inlet and is guided by the air distribution plate to enter the cavity, so that a cathode bed material can be in a fluidized state; and the two ends of the fuel cell tube are fixedly connected with the air distribution plate and the shell respectively. The reaction intensity in the cavity is enhanced through fluidization of the cathode bed material, meanwhile, the phenomenon of uneven temperature caused by decomposition and heat release of nitrous oxide is solved, and the decomposition rate of nitrous oxide and the safety of the fuel cell are improved.

Description

technical field [0001] The invention relates to the technical field of nitrous oxide tail gas treatment, in particular to a method and device for treating nitrous oxide tail gas by using a fuel cell. Background technique [0002] N 2 O is listed as one of the six major greenhouse gases because it severely depletes the ozone layer and causes the greenhouse effect, of which the global warming potential (GWP) is CO 2 310 times. During the production of nitric acid and adipic acid, the content of nitrous oxide in the waste gas produced can reach 50%. If the waste gas is not treated, about 0.25 tons of nitrous oxide gas will be emitted for every ton of adipic acid produced. [0003] N 2 O removal pathways include high-temperature thermal decomposition, nonselective catalytic reduction, and direct catalytic decomposition. Among them, direct catalytic decomposition is considered to be the most promising route because N 2 O is decomposed into nitrogen and oxygen under the actio...
