Description
Technical field
The invention belongs to industrial pot (kiln) stove to give up flue gas desulfurization and denitrification technical field, particularly relate to a kind of low-temperature circulating regeneration denitration catalyst device.
Background technology
From 2011, the coal production of China just exceeded 3,500,000,000 tons, accounted for the half in the whole world.Consumption of coal is 18.934 hundred million tons of oil equivalents, accounts for 90% of China Power fuel.While consumption coal resources, create a large amount of SO impairing human body
2, NOx, and SO
2, greenhouse effects caused by NOx, the environmental pollution such as acid rain and depletion of the ozone layer become the problem of the consistent concern of society at present.The research of the technology of various control atmosphere pollution has become the most urgent mission of various countries environmental worker.
" thermal power plant's nitrogen oxide technological policy for treatment " of Chinese Ministry of Environmental Protection's issue in 2010 explicitly points out, and nitrogen oxide is one of important prerequisite thing generating ozone, is also the major reason of forming region fine particles pollution and gray haze.Moreover, nitrogen oxide, as atmosphere pollution, has larger harm to health.On January 1st, 2012 rises, and country has promulgated " thermal power plant's air pollution emission standard ", is defined as 100mg/m by unified for the concentration of emission limit value of nitrogen oxide
3, this concentration of emission limit value requires for national all regions, is called as " standard the strictest in history ".Simultaneously, for solving day by day serious haze problem, State Council has issued " suggestion about accelerating development energy-conserving and environment-protective industry " for 2013, the work of strict deployment environmental protection aspect, what comprise environmental protection industry exempts from negative problem of reducing tax, can say that the environmental background pressure that air is administered is huge, be also that chance is pure simultaneously.
The improvement of boiler smoke claimed from 1998 to dedusting, gone through the process of desulphurization and denitration to PM2.5, require increasingly stringent, especially denitrating flue gas is at the early-stage at present.At present, various countries industry pot (kiln) stove give up flue gas desulfurization, denitration prevailing technology be utilize selective reduction (SCR) technology by the method for the removal of nitrogen oxide in flue gas.Selective reduction method utilizes ammonia (NH
3) restoring function to NOx, under the condition of 320 ~ 400 DEG C, utilize catalyst action NOx to be reduced to N air not being had to pollution effect
2and water, the meaning of " selective " refers to that ammonia only selects NOx to carry out reduction reaction.First this technique succeeded in developing in Japan in late 1970s, and after the eighties and the nineties, Europe and the U.S. drop into commercial Application in succession, now worldwide become the prevailing technology of large scale industry denitration of boiler smoke.
SCR system is made up of ammonia supply system, ammonia/air-injection system, catalytic reaction system and control system etc., and catalytic reaction system is the core of SCR technique, is provided with NH
3nozzle and the blow device of flyash, flue gas enters the SCR reactor being loaded with catalyst along flue, at the surface NH of catalyst
3nOx is reduced into N
2.As patent CN 102423604 A discloses a kind of combination type flue gas desulfurization denitrification apparatus.After this combination unit comprises booster fan, defeated ammonia pipe, adsorption tower, automatic alarm probe, active carbon entrance feeder, active carbon outlet discharger, saturated activity charcoal conveyer, clean active carbon conveyer, regeneration reactor, desorption, active carbon conveyer, vibratory sieve, active carbon supplement hopper, newly-increased active carbon conveyer, active carbon holding vessel, also comprise the active carbon in adsorption zone.And be divided into one and more than one complete, independently adsorption tower according to the size of exhaust gas volumn, each adsorption tower all can complete separately desulphurization denitration process.But utilize SCR method, SNCR method and the two mixing method realize desulphurization denitration, have following shortcoming:
(1) need to transform complete boiler;
(2) need in hot conditions 300-400 DEG C (SCR method), 900-1100 DEG C (SNCR method) work;
(3) SCR catalyst is due to containing V
2o
5in heavy metal (also referred to as vanadium titanium system), poisoningly rear secondary pollution is caused to environment, and need the process doing gas defence aspect during operation;
(4) SNCR method does not have catalyst, but very high to the temperature window control overflow in stove;
(5) because SCR method is mainly using ammonia as reducing agent, therefore operating cost is very high.
Along with the popularization of selective reduction (SCR) technology, the catalyst researching and developing and produce all kinds of forms of applicable SCR technology at home also arises at the historic moment, catalyst is core and the key of whole SCR system, the design of catalyst and selection are determined by flue gas condition, component, and three the interactional factors affecting its design are NOx removal efficiency, NH
3escapement ratio and catalyst volume.Mainly contain board-like, honeycomb fashion, corrugated plate dst and column four kinds in form, and in the majority with honeycomb fashion.
Because the method for SCR method and SNCR method and the two mixing realizes desulphurization denitration, above-mentioned condition need be met, and the high temperature denitrating catalyst of SCR method (also referred to as vanadium titanium system) is poisoning scrap after also must do the useless process of danger, therefore the above-mentioned cleaning system of Chinese kiln gas ubiquity in the actual motion of enterprise has the state of conflict, is to deal with the inspection of higher environmental protection departments mostly with operating type intermittently.
And from the improvement form analysis of current industrial furnace smoke:
(1) administer NOx both at home and abroad and mainly adopt selective reduction denitration technology (accounting for 96%);
(2) core of SCR denitration technology is catalyst, accounts for 40% ~ 60% of SCR system gross investment, and existing commercial catalyst is V
2o
5(WO
3)/TiO
2system (being commonly called as vanadium titanium system);
(3) China's denitrfying agent technology relies on import completely, though east Kytril, Chongqing far reach, Wuxi Long Yuan etc. has introduced Catalyst Production line, intellectual property is all external, need pay intellectual property expense, is vanadium titanium system;
(4) support material TiO
2the all required import of technology of preparing, Preparation equipment is partial domestic: TiO
2account for 80% ~ 90% of catalyst, 40% ~ 50% of totle drilling cost, the whole world only has the minority producer in Japan and Europe to produce TiO
2.
As can be seen from above-mentioned various situation analysis: industrial pot (kiln) stove at home and abroad used the at present flue gas desulfurization and denitrification that gives up realizes all under the high temperature conditions, and the desulfuring and denitrifying apparatus used under this hot conditions not only can not use under cryogenic, and high temperature denitrating catalyst is poisoning scrap after also must carry out the useless process of danger.Along with the development in desulphurization denitration field, low-temp desulfurization denitration will become the trend in this field following, therefore the present system for desulfuration and denitration in the urgent need to using under designing a kind of cryogenic conditions.
