With bottom pyramidal discharging bin；Ash-removing valve is connected on bottom pyramidal discharging bin.
Specifically, purifying tube, top feed platform and bottom pyramidal discharging bin surround SO2And the cleaning position of NOR；In cleaning position
Equipped with bracket, limestone particle is filled in cleaning position.
Specifically, the first desulfurization plate and the second desulfurization plate structure having the same；First desulfurization plate includes at least one mistake
Filter plate is uniformly provided with multiple through-holes on filter plate.
Specifically, pitch is 16mm between the hole of through-hole on filter plate, and through-hole diameter is Φ 6mm.
Specifically, filter bag is made of epoxy resin.
Specifically, silk screen is 120 mesh stainless steel cloths.
Compared with prior art, the utility model has the following beneficial effects: the utility model uses physics and chemistry simultaneously
Method handles flue gas, enters the first desulfurization plate, filter bag, the second desulfurization in the tail flue gas come out through gas energy-saver
Plate, silk screen, chemical sulphur removal mechanism, filter bag, air-introduced machine；Under the action of air-introduced machine, after flue gas enters the first desulfurization plate, enter
The filter bag made of epoxy resin, filter bag, to guarantee permeability, can be gone out in flue gas through filter bag with periodically cleaning is taken out
The second desulfurization plate is entered back into after coming, then flue gas completely has Φ 3mm lime stone by entering cleaning position, cleaning position after 120 mesh silk screens
Pellet, flue gas SO2 therein after lime stone is contacted with lime stone to react, and becomes purifying smoke, purifying smoke again into
Enter filter bag further to be purified, the filter bag and lime stone in device can be replaced daily, from our environment monitoring knots
Fruit sees its SO2With NOR close to European emission standard, it is better than national standard, which is that practical, initial cost is low, one
As small enterprise can install and effect is also fine.
Detailed description of the invention
