SCR denitration reactor

Abstract

The invention relates to the field of reactors, in particular to an SCR denitration reactor. The SCR denitration reactor comprises a shell, an air inlet mechanism, a discharging mechanism, a reactor body, a catalytic mechanism, a motor, a connecting rod, a fixing block, a spring, a clamping rod, a fixing plate, an iron wire cage, a shaking mechanism, a sliding block, a pressed block and an extrusion block. The motor drives the connecting rod to rotate, the connecting rod rotates to drive the fixing plate to rotate, a net frame is driven to rotate along with continuous rotation of the fixing plate, then the catalyst is driven to rotate, and therefore, the catalyst at all the parts of the reactor can be more evenly utilized; and further, along with rotation of the net frame, the extrusion block can be driven to rotate at the same time, the extrusion block is stressed to move when the extrusion block rotates to the position of the pressed block, then the screen frame is driven to move, and the above operations are continuously repeated, so the catalyst can be conveniently screened during use, the utilization condition of the catalyst in different areas is prevented from generating large difference, and the phenomenon of catalyst waste is reduced.

Description

technical field [0001] The invention relates to the field of reactors, in particular to an SCR denitration reactor. Background technique [0002] Denitrification refers to the process of removing nitrogen oxides from combustion flue gas. The importance of preventing environmental pollution has been sharply raised as a worldwide problem. The more mainstream processes in the world are divided into: SCR and SNCR. There is not much difference between these two processes except that the reaction temperature of SCR is lower than that of SNCR due to the use of catalyst in SCR. However, from the perspective of construction cost and operating cost, the investment of SCR is at least several times that of SNCR, or even More than 10 times. Among them, SCR is the most mature flue gas denitrification technology, which is a post-furnace denitrification method. [0003] However, in actual use, most of the catalysts inside the traditional SCR denitration reactor are fixedly placed. In thi...
