Description
Technical field
The utility model is related to the technical fields of municipal solid waste incinerator SCR denitration activation recovering, more particularly to
A kind of SCR low-temperature denitration catalysts on-line regeneration system.
Background technology
According to statistics, in by the end of November, 2017 by, China has put into operation, has been more than in the garbage burning factory total quantity built and established
610, wherein the garbage burning factory quantity to put into operation is at 260 or more, and the coming years will have and largely build incineration plant input
It uses.For garbage burning factory because it efficiently disposes the ability of house refuse, the predicament to solve garbage-surrounded city provides effective way.With
This simultaneously, with gradually spreading out for garbage burning factory, by Internet publicity, it is also more convex that the neighbour of garbage burning factory keeps away effect
It is aobvious.The social event mostly occurred forces garbage burning factory to be coped with using more environment-friendly and safer measure again.
Under this overall background, State Ministry of Environmental Protection has promulgated new garbage burning factory standard limit of smog release GB18485-2014
(the regulation small hourly values of NOx are no more than 300mg/Nm3, NOx annual averages are no more than 250mg/Nm3), substitute original GB18485-
2001 (provide that the small hourly values of NOx are no more than 400mg/Nm3), and encourage to create incineration plant using 2000 standard limit of smog release of European Union
(regulation NOx daily means are no more than 200mg/Nm for operation3).Denitration technology generally has SNCR technologies and SCR technology, simple to use
SNCR will consume a large amount of reduction medicament, it is necessary to coordinate SCR technology that could realize denitration high efficiency and economy.Although at the beginning of SCR
Invest larger, since neighbour keeps away the influence of effect and environmental protection supervise and examine, more and more newly-built incineration plants start to use or reserved SCR
Denitration.Nanjing north of the Changjiang River garbage burning factory is as domestic one of several incineration plants for attempting low-temperature SCR catalyst earliest, in practical throwing
It is also gradually recognized during fortune, SCR honeycombed catalyst activity is not always maintained at efficiently, but can gradually be declined, by most
First 50% or more denitration efficiency, operation 1 year and a half are down to less than i.e. within 30%, and there are catalyst failure or poisoning symptoms.
Country's SCR catalyst is used primarily in the fields such as coal electricity industry, glass ceramics kiln, coke-oven plant at present, and there are no special
