Embodiment
The embodiment of the utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning
Same or similar element is represented to same or similar label eventually or there is same or like element.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and cannot be construed to the utility model
Limitation.
Referring to shown in Fig. 1 to Fig. 4, the embodiment of the utility model provides a kind of high effective flue gas cleaning equipment, including tower
Body 1, the middle part of the tower body 1 are equipped with ammonium hydroxide jet pipe 2, and the lower section of the ammonium hydroxide jet pipe 2 is equipped with smoke-intake pipe 3, on the smoke-intake pipe 3
Equipped with distribution device, the distribution device includes gas distribution pipe 4, and both sides are provided with gas distributionbranch pipe 5 on gas distribution pipe 4, on gas distributionbranch pipe 5
Equally spaced to be provided with qi-emitting hole 6, the gas distribution pipe 4 is connected with smoke-intake pipe 3；So as to ensure to produce along baseplane in the course of work
Equally distributed gas.
The top of the ammonium hydroxide jet pipe 2 is equipped with fresh water spray pipe 7, and the top of the fresh water spray pipe 7 is equipped with demister, described
Demister includes the fixed disk 8 being fixed on 1 inner wall of tower body, and shaft 9, the shaft 9 are rotatably connected on the fixed disk 8
On be fixed with pallet 10,10 surrounding of pallet connects multiple spiral boards 11 being uniformly arranged, and the spiral board 11 is obliquely installed.
When flue gas flows through the device, generation rotates, formation centrifugal force, and droplet, flue dust, the slurries in flue gas are got rid of to tower by rotary centrifugal force
Wall, achievees the purpose that efficient removal droplet and grit in flue gas, and spiral board 11 can design one layer, two layers, or three according to demand
Layer, or more layer, form the structure of individual layer or multiple field.
The bottom of the tower body 1 is oxidation sink 12, and the liquid level of the oxidation sink 12 has aerator, the exposure
Device of air includes the aeration tube 13 that more interconnections are in " X " type structure, and the connection of the aeration tube 13 is crossed to form admission, exposes
Set on tracheae 13 and be interval with multiple solarization air caps 14.Increased by the design aeration area of 13 cross arrangement of aeration tube
Add, the bottom of the tower body 1 is equipped with ash discharging hole 15, and the top of the tower body 1 is equipped with purified gas outlet 16.
