Background technology
Catalyst is the core of whole SCR denitrating system, along with increase the service time of catalyst, urgesCan there is deactivation phenomenom in agent, its main cause mainly comprises 4 aspects gradually: (1) arsenic, alkali metalCatalyst poisoning Deng causing: arsenic alkali metal diffuses into the microcellular structure of catalyst under hot conditions,Surface at catalyst reacts, and occupies and destroy the activity site of catalyst, thereby causes catalystInactivation. (2) obstruction of catalyst: the ammonium salt sedimentation forming in short grained flying dust and course of reaction existsIn the aperture of catalyst surface, cause catalyst to stop up, obstruction NOx, NH3, O2 arrive catalyst activityProperty surface, thus catalysqt deactivation caused. (3) high temperature causes sintering, active component volatilization: catalysisAgent long term exposure allows hot environment more than maximum operating temperature can cause catalyst activity position burning in itKnot, causes catalyst granules to increase, and specific area reduces, a part of active component volatilization loss, therebyCatalyst activity is reduced. (4) mechanical wear: in the installation of catalyst, Renewal process, catalystBe subject to percussion and then its surface reactive material is reduced; In addition, due to the catalysis in SCR reaction towerAgent is arranged vertically, and flue gas autoreaction top of tower vertically downward parallel catalyst flows, in larger air speed conditionUnder, 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 that air purge, pickling are except alkali, host are supplemented, drying and roasting waitedJourney, but owing to being newborn industry, be quite fruitful about the method for air purge, but specifically establishThe purging and dust removing device of meter is more rare on market, and blow device of the prior art exists easily and occursThe problem such as subproblem, complex structure, inconvenient operation, dust collecting effect are not good.
