Description
Technical field
The present invention relates to catalyst regeneration field, particularly relate to a kind of SCR denitration reclaim equiment cleaning processing apparatus.
Background technology
Catalyst is the core of whole SCR denitration system, along with the service time of catalyst increases, deactivation phenomenom can be there is gradually in catalyst, its main cause mainly comprises 4 aspects: the catalyst poisoning that (1) arsenic, alkali metal etc. causes: arsenic alkali metal diffuses into the microcellular structure of catalyst under the high temperature conditions, react on the surface of catalyst, occupy and destroy the activity site of catalyst, thus causing the inactivation of catalyst.(2) blocking of catalyst: the ammonium salt sedimentation formed in short grained flying dust and course of reaction, in the aperture of catalyst surface, causes catalyst blockage, hinders NOx, NH3 etc. to arrive catalyst activity surface, thus causes catalysqt deactivation.(3) high temperature cause sintering, active component volatilization: catalyst is exposed to it for a long time and allows hot environment more than maximum operating temperature that catalyst active sites can be caused to sinter, catalyst granules is caused to increase, specific area reduces, part active component volatilization loss, thus makes catalyst activity reduce.(4) mechanical wear: in the installation, Renewal process of catalyst, catalyst is subject to percussion and then its surface reactive material is reduced; In addition, because the catalyst in SCR reaction tower is arranged vertically, the parallel catalyst flowing vertically downward of flue gas autoreaction top of tower, under larger space velocities, the large particulate matter in flue gas also makes catalyst surface active material few to the abrasive action of catalyst.
The regenerative process of catalyst comprises the processes such as air purges, pickling removes alkali, host is supplemented, drying and roasting, but owing to being nascent, cleaning processing apparatus of the prior art uses and there will be subproblem or inconvenient operation, such as: 1) ultrasonic cleaning dynamics is held inaccurate, do not find the optimum vibration frequency of removing contamination, poor effect of removing contamination.2) processing time also controls inaccurate, overlong time easily damages our product, and the time is too short, can not reach best effect of removing contamination.3) in part treatment system, it is perfect not that safety system does, and easily causes the damage of equipment and the shortening in life-span.
