xconcentration can reach 3000 ~ 5000mg/Nm
3, SO
2concentration 200 ~ 500mg/Nm
3, dust concentration is lower; During using petroleum coke powder as fuel, NO
xconcentration is generally at 1500 ~ 3000mg/Nm
3, SO
2concentration is higher is 1500 ~ 3000mg/Nm
3, dust concentration 500 ~ 900mg/Nm
3.The fluctuation of glass furnace exit gas temperature is large, and generally between 220 DEG C ~ 300 DEG C, flue dust composition is mainly the organic matter, alkali metal oxide, the SO that do not burn
3deng, ratio resistance is 10
6~ 10
10between Ω cm, primary particles thing average grain diameter is at about 24 μm, and the dust discharged after electric cleaner process in flue gas is thinner, average grain diameter is at 8 μm, and fusing point is lower, and viscosity is strong, enter into denitrating catalyst surface, because of the blocked and active obvious decline of catalyst surface, SO simultaneously
3there is extremely strong oxidisability and corrosivity, have larger destruction to the structural stability of catalyst.
At present, the optional technical equipment of glass furnace fume treating flour dust normally electric cleaner.But because of the particularity of glass furnace fume, but find the stability of electric cleaner from practical effect, efficiency of dust collection still needs to be improved further.Still have in electric cleaner exiting flue gas and be certain densityly rich in the organic matter, the SO that do not burn
3, alkali metal oxide fine dust, these fine dirt have extremely strong viscosity, and follow-up SCR denitration can be made poisoning, and simultaneously the dust of a large amount of fine particle size also can the minute aperture of blocking catalyst, thus makes catalysqt deactivation, and catalyst life is shortened in aggravation.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of sticky dust capturing device, can meticulous trapping sticky dust, and to reduce, the blocking of follow-up denitrating catalyst, alkali metal are poisoning, the risk of catalyst structure unstability, extend the denitrating catalyst life-span.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: a kind of sticky dust capturing device, comprise electric cleaner and Benitration reactor, be communicated with between the exhaust pass of described electric cleaner and the inlet flue duct of Benitration reactor and form passage, described passage is being provided with import air door, trap and export the breeze door from electric cleaner successively on the direction that Benitration reactor extends.The entrance of electric cleaner communicates with the outlet of glass furnace, and the ash-laden gas that kiln comes enters electric cleaner and carries out pre-dedusting, the organic matter do not burnt, SO in flue gas
3, metal oxide, SiO
2remove etc. most of fine dust, then pass through from the passage between the exhaust pass and the inlet flue duct of Benitration reactor of electric cleaner, in the process, gas first traps the sticky dust in gas further by trap through import air door arrival trap place, then enter Benitration reactor from export the breeze door.
As preferably, described trap comprises framework and is arranged on the dust absorption net on framework.
As preferably, described dust absorption net is the mesh sheet structure that two layers and above woven wire are formed by stacking.
As preferably, described dust absorption net is the string bag structure be made with wire.
As preferably, the porosity of described dust absorption net is 50% ~ 60%.
As preferably, the flue gas flow velocity of described trap place passage is 2.5 ~ 4.0m/s.
As preferably, the flue gas flow velocity of trap place passage is 3.0m/s.
As preferably, the passage at described trap and its position place is slidably connected.
As preferably, described sticky dust capturing device also comprises reducing agent adding equipment, and the outlet of described reducing agent adding equipment is by pipeline and the channel connection between export the breeze door and Benitration reactor.
As preferably, described import air door, trap, export the breeze door be redundant parallel configuration on passage.Import air door, trap, export the breeze door all adopt at least two groups, and one group uses all the other for subsequent use, and the trap forming redundant parallel configuration is arranged, and can switch online and change or cleaning trap.
Beneficial effect:
A kind of sticky dust capturing device that the utility model adopts technique scheme to provide, is arranged by trap, more efficiently can trap the fine dirt of viscosity of escaping from electric cleaner, has positive effect to raising catalyst activity, service life; Import air door and export the breeze door are set, the gas flow rate by trap and Benitration reactor can be controlled, make the reaction effect of the trapping effect of trap and Benitration reactor best.
