Disclosed are a reactor integrated with air preheating and denitration, and a reaction method therefor. The reactor comprises a rotary catalyst body structure, a shell (10) outside the rotary catalyst body structure, and a gas inlet and outlet channel of an upper surface and lower surface of the shell (10). The gas inlet and outlet channel is separated into three parts, i.e. a smoke inlet and outlet channel (1), a reductant inlet and outlet channel (2) and an air inlet and outlet channel (3). The rotary catalyst body structure is cylindrical, and comprises a central shaft rotor (4) and a multi-layer circular catalyst layer (5) which is capable of rotating around the central shaft rotor (4). The multi-layer circular catalyst layer (5) is separated into an air region (6), a smoke region (7) and a reductant region (8) by a radial sealing plate and an axial sealing plate. The catalyst in the reactor is alternately circulated in the smoke region (7), the reductant region (8) and the air region (6). The catalyst will perform the heating-reheating-cooling process of the catalyst layer with the rotation of the reactor. Because of a different temperature and reaction atmosphere of each region of the reactor, it is beneficial to perform the air preheating and denitration processes, thereby improving the denitration efficiency of the reactor. |
