Description
Technical field
The utility model relates to a kind of dedusting defogging equipment, particularly carries out the flue gas static composite dedusting demister of deep purifying processing for coal-fired power plant's wet desulphurization tail end flue gas.
Background technology
Some industry taking fire coal as the energy, as the large enterprise such as thermal power generation, metal smelt need to consume a large amount of fire coals every day, a large amount of dust that coal combustion produces are with fume emission, and because flue dust is very big to environmental hazard, therefore domestic have strict restriction to smoke dust discharge concentration.For example, national standard (fossil-fuel power plant atmospheric pollutant emission standard GB 13223-2011) clearly regulation smoke dust discharge concentration limit value be 30 mg/Nm
3, the concentration of emission limit value of key area is 20 mg/Nm
3.For reaching dust emission standard, coal burning system must arrange smoke dust-removing equipment.At present, smoke dust-removing equipment is mainly the kinds such as electrostatic precipitator, sack cleaner, electric-bag complex dust collector.
Conventionally, the purified treatment of the large coal-fired boiler flue gas in thermal power plant is except dedusting, and it must also carry out desulphurization reaction by absorption tower, and most of thermal power plant completes SCR denitration transformation substantially in recent years.Flue gas discharges after denitration, dedusting, desulfurizing and purifying.Conventionally, discharge flue gas is provided with the air preheater of recovery waste heat more, and after air preheater or SCR Benitration reactor, desulfuration absorbing tower (the lower absorption tower of being called for short) arranges deduster before, makes dust content be down to <30 mg/Nm
3.
But, the process of wet desulphurization of flue gas is taking lime stone slurry as absorbent, in absorption tower, lime stone slurry contact with flue gas in the mode of spray atomizing and with flue gas in sulfur oxide reaction, generate the materials such as calcium sulfate (gypsum), therebetween, between the vaporific slurries of rising flue gas and decline, there is great mass-and heat-transfer process, the flue gas tiny gypsum slurries of part (gypsum slurries of escape) of can carrying under one's arms in uphill process in absorption tower, these gypsum slurries of escaping with flue gas can form new dust, cause the dust concentration of flue gas again to increase, although be generally provided with mechanical demister at top, absorption tower, but the demist ability of mechanical demister is little, demister passage is easily stopped up by gypsum slurries, be difficult to the gypsum slurries that Ex-all flue gas is carried secretly, the gypsum slurries of considerable part is with fume emission, cause " gypsum rain ", contamination phenomenon such as " great Bai cigarettes " happens occasionally.Therefore, even if flue gas has been down to dustiness <30 mg/Nm before desulfurization
3, but for above-mentioned reasons, the flue gas after desulfurization is still difficult to realize dust qualified discharge.For making up this phenomenon, patent documentation CN 101460251 A, CN 102500188 A, CN103055644 A, CN 202538927 U etc. have reported in desulfuration absorbing tower outlet and have set up wet cottrell, for to the further deep purifying of flue gas.But wet cottrell floor space is large, system complex, invests highly, and a lot of thermal power plants site condition cannot meet the requirement of setting up wet cottrell.And before entering desulfuration absorbing tower, flue gas has passed through dust removal process, flue dust has approached concentration up to standard, only in order to remove a small amount of flue dust that slurries are carried under one's arms and increase newly, drop into the newly-built a whole set of large-scale wet-type electrostatic precipitation system of huge fund, its economy is very low, and investment waste is serious.
Summary of the invention
