Description
Technical field
The utility model relates to glass furnace exhaust-gas treatment field, is specifically related to a kind of glass flue gas pollutant and assistsSame purifier.
Background technology
The smoke characteristic of glass furnace is that pollutant complicated, pollutant levels are high, dust viscosity is strong, sourSO in the feature, particularly flue gas such as property is strong, corrosivity is strong3、NOxDense, burn petroleum coke inferior for mixingWhen powder, SO in flue gas2Also very high, dust has that fusing point is low, particle is thin, than features such as resistance are low, and flue gas temperatureSpend highly, in above-mentioned flue gas, the collaborative improvement technical difficulty of combined pollutant is very large.
There are approximately 390 left and right of glass furnace of scale, approximately 5000 left and right of small-sized glass furnace in the whole nation. WithCountry to PM2.5That administers gos deep into, SO in glass furnace fume2、SO3、NOX、PM2.5Improvement become to attach most importance toPoint perpetual object.
Glass furnace adopts several fuel conventionally: (1) natural gas; (2) petroleum coke powder; (3) coal gas.In the time adopting natural gas as fuel, flue-gas temperature is slightly high, NOxConcentration can reach 3000～5000mg/Nm3，SO2Concentration 200～500mg/Nm3, dust concentration 300～500mg/Nm3; During using petroleum coke powder as fuel, NOXConcentration is generally at 1500～3000mg/Nm3，SO2Concentration is higher is 1500～3000mg/Nm3, dust concentration500～900mg/Nm3, but common feature is SO in flue gas3Dense. The cigarette that glass furnace need purifyTemperature degree is generally between 220 DEG C～400 DEG C, and flue dust composition is mainly SO3, the end organic matter, the alkali gold that burnBelong to oxide (Na2O、K2O), alkaline earth oxide (CaO) etc. and part inert substance are (as SiO2Deng),Be 10 than resistance range4～109Ω cm, particle average grain diameter is at 25 μ m, dust have fusing point lower,The features such as hygroscopicity is strong, adhesiveness, corrosivity are strong.
Because thering is vanadium in denitrating catalyst, SO in glass furnace fume2Concentration is not low yet, causes SO in flue gas3Higher, adsorb SO3Above-mentioned dust directly contact and very easily stick to catalyst surface with catalyst, can adhere toAt catalyst surface, blocking-up reducing agent and NOXEnter catalyst micro channel, cause physical inactivation, withTime high concentration SO3The adhesive of meeting heavy corrosion and oxidation catalyst, declines rapidly its structural stability,Cause cracking, the disintegration avalanche of catalyst.
In addition, in glass furnace fume, there is certain density SO2, SO sometimes2Concentration is up to 3000mg/m3,Can adopt wet desulphurization or dry type/half dry type integrated technology to carry out desulfurization processing. Adopt dry type/half dry type integratedWhen sulfur removal technology, adoptable desulfurizing agent comprises Na2CO3、CaO、Ca(OH)2Deng, for increasing grey mobility,Can mix simultaneously and throw a certain proportion of flyash, also can further improve the utilization rate of desulfurizing agent simultaneously. After desulfurizationThe optional electric cleaner of dedusting method or desulfurizing dust-collector. Because flue-gas temperature is high, flue dust fusing point is low and have a utmost pointStrong viscosity, the filter bag of sack cleaner is difficult to select, even if adopt high-temperature filter material, service life is not conventionallyExceed 1 year, and often have the risk of scaling loss, obstruction, operation crushing is larger, and operating cost is very high; High-temperature electricDeduster is except considering that, temperature factor, particle average grain diameter is thin, flue dust fusing point is low and viscosity is strong, even if adoptStill having many technical barriers to study with electric cleaner captures.
