The invention discloses an automatic sequence-changing assembly rack for out-of-stock catalysts, which belongs to the field of installation equipment for selective denitrification catalysts, and specifically relates to a device for automatically changing the initial position of out-of-stock catalysts to facilitate prolonging the average service life of the catalysts. It is characterized in that it includes a replacement frame body, and several catalyst fixing frames are arranged on the replacement frame body, and the catalyst fixing frame can fix and clamp and fix the catalyst; the catalyst fixing frame can pass through the replacement frame body The power unit drives the changing position. The invention can prolong the catalytic life by replacing the spare catalyst assembly from the periphery or the periphery to the center or the place where the flue gas is concentrated, and avoid the problems of different lifespans of the catalysts installed at the same time and the high cost of overall replacement.
Description
technical field [0001] The invention belongs to the field of installation equipment for selective denitration catalysts, in particular to a device for automatically changing the initial position of an out-of-stock catalyst so as to prolong the average service life of the catalyst. Background technique [0002] Denitration catalyst generally refers to the catalyst used in the denitrification system of the power plant. The filtered flue gas contains a large amount of particulate matter, which is easy to cause deposition on the surface of the catalyst. After long-term use, it is prone to ash accumulation failure, resulting in a reduction in the ability to filter and reduce nitrogen oxides. , and eventually scrapped. Since the polluted flue gas is mainly concentrated in the middle or lower part when it passes through the exhaust pipe, the failure of the out-of-stock catalyst does not have simultaneous identity. [0003] In order to solve the above problems, the applicant has de...
