Pollutant is trapped and is dissolved by moisture film plate blocking apparatus 22 again, and flue gas is gone after above-mentioned purification process three times by demister 23
Except the water mist carried secretly in flue gas, double loop flue gas is discharged through exhanst gas outlet 5 in the clean flue gas for being finally reached " minimum discharge " standard
Purifier.
When double loop smoke eliminator 1 is abnormal failure suddenly because of external cause, can close smoke inlet A 4 or
Smoke inlet B 5, flue gas only by a circuit of middle storehouse A 10, lower storehouse 12, the uptake flue of middle storehouse A 10 and upper storehouse A 8 into
Row gas cleaning carries out cigarette by another circuit of middle storehouse B 11, lower storehouse 12, the uptake flue of middle storehouse B 11 and upper storehouse B 9
Gas purifies, and final clean flue gas up to standard is discharged from exhanst gas outlet 5.
SO in flue gas2, dirt particle and PM2.5 pollutants below trapped by absorption slurries, dissolving, absorb after generated
Salts substances are discharged through slurry pump.Meanwhile fresh absorption slurries also continuously enter from benefit slurry pipe in lower storehouse 12, protect
Liquid level equilibrium is demonstrate,proved, the solution of discharge can carry out by-product processing.Preferably, heavy to prevent the absorption slurries in lower storehouse 12 from occurring
It forms sediment, slurries can also be set in lower storehouse 12 and stir device 20, agitating device 20 can carry out the absorption slurries in lower storehouse 12 uninterrupted
Stirring, while oxidation air can be also set for providing oxidation air.
The selection of the diameter of the housing of the utility model can determine that flue gas is in middle storehouse A 10 and middle storehouse B according to processing exhaust gas volumn
11 flow velocity considers according to 0.5~10m/s, known to flue gas flow, can calculate the cross-sectional area of shell.It is bubbled
Flue gas flow rate in pipe 17 considers according to 3~25m/s, known to flue gas flow, can calculate the transversal of bubbling pipe
Area.
The double loop smoke eliminator 1 of the utility model, flue gas are divided into two tunnels, and the gas cleaning process per road is three
It is secondary, flue gas pollutant is removed for the first time（It refers mainly to：SO2, dirt particle）It is storehouse in utilizing（A 10 or B 11）In spray equipment (A
13 or B 14) carry out, due to the SO in sprayed slurry droplet and flue gas2, dirt particle collides and gas-liquid mass transfer, therefore quilt
Trapping and absorption；Secondary removing flue gas pollutant（It refers mainly to：SO2, dirt particle, PM2.5 pollutants below）It is to utilize lower storehouse
It is carried out in the lower absorption of storehouse 12 slurries of 18 gas outlet of bubble generator embedment of bubbling pipe 17 and bottom in 12；Cigarette is removed three times
Gas pollutant（It refers mainly to：SO2, dirt particle, PM2.5 pollutants below）It is to utilize upper storehouse（A 8 or B 9）In moisture film plate block
It cuts device 22 and traps and dissolve remaining rareness flue gas pollutant in flue gas again；Above-mentioned two, flue gas pollutant is removed three times
Principle is the application of the positive and negative direction of bubble tower principle, therefore to SO2, dirt particle, PM2.5 pollutants below have it is extremely smart
Thin removing effect.
It is obtained through case history and experiment：It can make boiler and the industry of burning high sulfur coal using double loop smoke eliminator
The flue gas synchronization of kiln discharge, continuous realization " minimum discharge ", can make the SO in flue gas2Concentration is from 6000 mg/Nm3It drops to
15mg/Nm3Hereinafter, SO2Removal efficiency up to 99.5% or more；It is as follows to the particle analyte detections below of PM2.5 in flue gas：Grain size ＞
2.0 μm of dirt granule capturing rate is 99% or more, and grain size is that 0.6~1.0 μm of dirt granule capturing rate is about 82%；And it can be to having
Evil air pollutants are trapped：90% is more than to hydrogen chloride and hydrogen fluoride removal rate, to trace metal removal rate 80%~98%,
It is 46% to mercury and cadmium removal rate, is 67% to selenium removal rate, is 95% or more to vanadium and arsenic removal rate.
The foregoing is merely the test datas of the utility model and preferable embodiment, not limiting this hair
Bright, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in the present invention
Protection domain within.
