Description
Technical field
The present invention relates to desulphurization denitration technical field, particularly relate to a kind of honeycomb type denitrification catalyst module dry reclamation system and method.
Background technology
At industrial circles such as electric power, cement, iron and steel, coal is all by as main energy and material, a large amount of pollutants can be discharged during coal burning, mainly comprise Absorbable rod and enter solid particulate matter, carbon dioxide, sulfur dioxide and nitrogen oxide (NOX) etc., bring the problem of environmental pollutions such as greenhouse effects, acid rain, photochemical fog thus.Nitrogen oxide (NOX) has stronger stimulation and injury effect to eye and respiratory system, also participates in the formation of acid rain and photochemical fog.
The control of polluting for the NOX of burning generation mainly contains 3 kinds of methods: 1. fuel denitrogenation; 2. combustion system and production technology is improved; 3. denitrating flue gas.Fuel denitride technology is developed so far not yet very well, awaits continuing research from now on.A large amount of research work is done to the improvement of combustion system both at home and abroad, develop many lower NOx combustion technology and equipments, and apply on some boilers and other stoves, but because some lower NOx combustion technology and equipments reduce efficiency of combustion sometimes, cause imperfect combustion, the energy can not make full use of, and equipment scale increases thereupon, the reduced rate of NOX is also limited, so lower NOx combustion technology and equipment not yet reaches the comprehensively practical stage at present.Denitrating flue gas is most important method in NOX control measure at no distant date, and SCR (SCR) denitration technology is remarkable to the removal effect of NOX, and technology maturation is one of current most widely used gas denitrifying technology.In the out of stock system of whole SCR, catalyst is core material, and the proportion accounted in equipment direct investment is larger.Wherein using maximum is vanadium titanium base honeycomb-shaped SCR denitrating catalyst.The scheme that the catalyst module major part of SCR denitrating system takes high dirt to arrange, run the denitration performance of a period of time rear catalyst can decline, show as that reducing agent consumption increases, the oxygenation efficiency of sulfur dioxide rises, denitration amount declines, the resistance rising etc. of denitrating system.Catalyst activity reduction, when not reaching denitration requirement, will more catalyst changeout.Catalyst under changing will carry out regenerating or discarding, and discarded mode generally processes according to danger wastes, and such as broken landfill, melting are reclaimed and be used as the processing modes such as construction material.Consider that the price of denitrating catalyst is higher, if realize catalyst regeneration efficiently, will greatly save denitration cost.
During SCR denitrating system runs, in flue gas, Cucumber can deposit at catalyst surface gradually.The alkali metal wherein existed with aerosol form and the compound of the element such as arsenic can make catalyst lose activity, and block, cover, the reason such as erosion can make catalyst generation physics inactivation.Existing catalyst recovery process, is generally through dry type and purges and the pre-treatment of wet dip two step, then carries out the process such as active physical load and drying.The device of a set of regeneration is provided in a prior art, comprises the equipment carrying out compressed air purging, cleaning, spark etc.In another prior art, give a kind of being reached by bubbling flowing wash out pollutant, recover the device of catalyst denitration activity.In another prior art, mainly give a kind of technique adopting autoclave to carry out catalyst reaming in regenerative process, but the expanding agent used in this technique such as methyl alcohol etc. can cause secondary pollution, and under Elevated Temperature Conditions, realize release rapidly there is hidden danger in safety and this technique exists the processing time waits so long problem.
In prior art, all there is denitration speed slow, the problems such as denitration effect is not good in no matter wet denitration or Dry denitration, and wherein wet denitration also exists the problem reducing denitration anti-oxidant active and reduce, and easily produces secondary pollution in denitrification process.So provide a kind of novel denitration mode to be this area problem demanding prompt solution.
