Description
Technical field
The present invention relates to energy-conserving and environment-protective field, refer in particular to a kind of high-efficiency energy-saving desulfurizing denitration dust removal system.
Background technology
Current power plant's denitration technology is SNCR (arcola), the medium-and-large-sized boiler of SCR() or sncr and scr combined denitration (medium-and-large-sized boiler), after denitration, adopt electricity, bag mechanical and hydraulic combined dust device or sack cleaner dedusting, after dedusting, adopt wet desulphurization.For obtaining the stricter environmental requirement of country up till now, what desulfurization adopted at present is the Wet Flue Gas Desulfurization Technique such as cascade towers or Dan Ta two-region, humidification-type electric precipitation after wet desulphurization.
Containing vanadic anhydride in the catalyst of SCR denitration, vanadic anhydride has moderate toxicity, and by catalyst, (in the flue gas of coal-powder boiler, dust content is approximately 20 grams/m to flue gas
3) time, there is very large abrasive action to catalyst; Through catalyst flue gas with wear and tear from catalyst the composition such as vanadic anhydride, cause flyash to have certain toxicity, limit the scope of application of flyash; The flyash that the alkali metal oxide contents such as calcium are high is very easy to the blocking and the disabler that cause catalyst.Catalyst needs to change because of the catalyst failure that wear damage and disabler cause, and causes operating cost to increase.And flyash, easily resulting in blockage by during catalyst, needs frequently to use soot blower, current scr build and operating cost high, can not ensure that when boiler at low load denitration normally runs.And electrostatic precipitator is high due to technology, cost and use cost at present, is seldom used in before SCR and carries out dust removal process; Sack cleaner has no idea to use before SCR at present; Cyclone dust collectors technology uses the dust that can remove about 90% before SCR, so needs to use electric precipitation or sack cleaner SCR successor, and not so wet desulphurization below cannot run well.
The pressure drop of current sack cleaner at more than 1000Pa, substantially at 1800Pa during use; Electric precipitation in use approximately pressure drop at more than 200Pa, but need high voltage direct current be used when running.
Current wet desulphurization absorption tower is that Multi-layer sprinkling runs, and is generally more than 3 layers, many to 6 layers.The power of the slurry circulating pump of 600000 units is more than 1000 kilowatts.Series connection double tower technology etc. is used in sulphur coal district or key area.The power of 600000 generator set desulfurization tower oxidation fans more than 500 kilowatts, oxidation wind flow 10000 cubes/per hour more than, be generally operation more than two.The pressure drop on absorption tower is at more than 800Pa.It is 100 kilowatts in 600,000 unit general 100Pa pressure drop air-introduced machine consumed power.Obtain environmental protection new national standard requirement up till now, prior art or be double tower two-region technology; It is Dan Ta two-region technology (needing to increase the volume on spraying layer and absorption tower).The requirement of ultra-clean environmental protection add power plant the construction of environmental protection facility and operating cost huge.
Therefore, the present inventor re-starts research from theory, and develop a kind of high-efficiency energy-saving desulfurizing denitration dust removal system, this case produces thus.In this case, flue gas is successively through SNCR denitration, economizer, middle high-temperature electric cyclone dust removal (had the cyclone electrostatic precipitator being less than 100Pa pressure drop at present, lower than the energy consumption of current electrostatic and sack cleaner.), SCR denitration, air preheater, flue wet desulphurization, absorption tower wet desulphurization, wet type Electrocvclone, enters chimney.Cancel current technology after SCR, use electric precipitation or sack cleaner.
The denitration of this case is SNCR and SCR combined unit, wherein carries out Electrocvclone before SCR, and what reduction SCR was in operation blows grey number of times, the service life of extending catalyst; The disengagement section of this case is flue, the desulfurization of two-region, absorption tower, in flue desulfurization district, serum recycle transport pump slurries amount is low, and in practical sulphur removal, liquid-gas ratio is high, and efficiency is high, absorption tower zone, due to the slurry nozzle effect on tower wall, ensures that flue gas slurries in absorption tower fully contact with oxygen.So this case is higher than the efficiency of current denitration, dedusting, desulfur technology, energy consumption is low, construction cost is low, operating cost is low.
