The power resources that baffle 14 and dirt filtrating screen 15 rotate are the flue gas of circulation, constitute flabellum shape structure between several baffles 14,
And one layer of dirt filtrating screen placed vertically 15 is installed between two neighboring baffle 14, so that flue gas, which drives, separates 16 rotations,
It is circulated back and forth inside partition 16 as partition 16 is rotated to constantly be filtered by dirt filtrating screen 15 into the flue gas inside partition 16,
It is taken off until partition 16 is turned to except the pipeline nozzle position flue gas connected between dirt barrel 2 and desulphurization denitration cabinet 4 is just discharged into desulfurization
Inside nitre cabinet 4, such mode not only make flue gas when except 2 self-filtering of dirt barrel without by external driving device come band
15 activity of dirt filtrating screen is moved to promote filter effect, and increases flue gas in the time for removing 2 internal stops of dirt barrel, to effectively mention
Filter effect is risen, and the spacing between dirt filtrating screen 15 is larger, and places vertically, thus when removing the shell except dirt barrel 2
Can the two sides directly to dirt filtrating screen 15 clean, it is more convenient；
Due to the presence of mixing channel 20, so that flue gas can be sufficiently mixed with ammonia before carrying out denitration to flue gas, from
And the NO in flue gasXIt can be sufficiently mixed with ammonia and be converted to N to the greatest extent under the catalysis of active carbon2Discharge, thus
Effectively promote denitration effect；
Since the desulfuration pipeline 17 of U-shaped structure, denitration pipeline 24 cooperate the peace of corresponding position on 4 outer wall of desulphurization denitration cabinet
Hole is filled, so that active carbon stick 26 is more convenient when taking out, joint chair 18 need to only be extracted from mounting hole, due to active carbon stick
26 one end are connected with Pneumatic extension bar 33, and active carbon stick 26 passes through to be flexibly connected between Pneumatic extension bar 33 and 25 inner wall of outer tube,
And active carbon stick 26 is from the ejection completely of 25 inside of outer tube after the elongation completely of Pneumatic extension bar 33, so that active carbon stick 26 can be in gas
29 driving Pneumatic extension bar 33 of pump separates under the action of extending with outer tube 25, so that convenient clean, more active carbon stick 26
It changes.
In the use of the present invention, accessing joint chair 18, joint chair from three mounting holes inside on 4 side wall of desulphurization denitration cabinet first
The outer tube 25 with active carbon stick 26 accesses desulfuration pipeline 17, inside denitration pipeline 24 after 18 accesses, and by air inlet pipe 1 and cigarette
The pipeline that gas largely discharges is connected, then by 10 starting device of power supply, firstly, flue gas enters from air inlet pipe 1 except in dirt barrel 2
Portion, flue gas are acted in the circulation process on baffle 14, and are entered inside partition 16 one by one, due to several baffles 14
Between constitute flabellum shape structure, and one layer of dirt filtrating screen placed vertically 15 is installed between two neighboring baffle 14, thus cigarette
Gas drive separates 16 rotation, into partition 16 inside flue gas with partition 16 rotate partition 16 inside back and forth circulation thus
It is constantly filtered by dirt filtrating screen 15, until partition 16 is turned to except the pipeline nozzle position connected between dirt barrel 2 and desulphurization denitration cabinet 4
It sets flue gas to be just discharged into inside desulphurization denitration cabinet 4, such mode not only makes flue gas when except 2 self-filtering of dirt barrel without passing through
External driving device promotes filter effect to drive 15 activity of dirt filtrating screen, and increases flue gas and stop inside except dirt barrel 2
The time stayed, so that filter effect is effectively promoted, and the spacing between dirt filtrating screen 15 is larger, and places vertically, thus
When removing the shell except dirt barrel 2 can the two sides directly to dirt filtrating screen 15 clean, it is more convenient.Then, it is de- to flow into desulfurization
Flue gas inside nitre cabinet 4 enters desulfuration pipeline 17 under the extraction of the first aspiration pump 5, and flue gas enters outer tube 25 from air inlet 32
Inside carries out desulfurization process, and subsequent flue gas is discharged from gas outlet 31, flue gas quilt after handling twice inside desulfuration pipeline 17
First aspiration pump 5 is taken out toward delivery pipe 19 and is sent into inside mixing channel 20, and the ammonia inside ammonia case 6 is sent by the second aspiration pump 7
Inside mixing channel 20, the driving mixing of motor 21 fan 22 inside mixing channel 20 mixes flue gas with ammonia, and then takes out in third
Under the action of air pump 8, the flue gas mixed with ammonia is sent into denitration pipeline 24 and carries out denitration process, is discharged after the completion from gas outlet 31
And chimney 9 is sent to by third aspiration pump 8 and is discharged, due to the presence of mixing channel 20, so that before carrying out denitration to flue gas, flue gas
It can be sufficiently mixed with ammonia, thus the NO in flue gasXIt can be sufficiently mixed with ammonia and maximum under the catalysis of active carbon
Degree is converted to N2Discharge, to effectively promote denitration effect, and due to the desulfuration pipeline of U-shaped structure 17, denitration pipeline
The mounting hole of corresponding position only needs so that active carbon stick 26 is more convenient when taking out on 24 cooperation 4 outer walls of desulphurization denitration cabinet
Joint chair 18 is extracted from mounting hole, since 26 one end of active carbon stick is connected with Pneumatic extension bar 33, active carbon stick 26 passes through
Be flexibly connected between Pneumatic extension bar 33 and 25 inner wall of outer tube, and after the elongation completely of Pneumatic extension bar 33 active carbon stick 26 from outer tube
25 inside completely ejection, thus active carbon stick 26 can air pump 29 drive Pneumatic extension bar 33 extend under the action of with outer tube 25
Separation, so that convenient clean active carbon stick 26, replace.
