Enter in reduction of speed dust pelletizing system, the temperature of the gas come out from heat exchange reduction of speed dust pelletizing system is less than or equal to 300 DEG C；
It is less than 3.0g/m when the flow velocity of the gas come out from heat exchange reduction of speed dust pelletizing system is less than 15m/s and dustiness3When, then
It is sent into absorption cleaning system；
Flue gas from reduction of speed dust pelletizing system come out after flow velocity to be less than 15m/s and dustiness be less than 3.0g/m3；From then reduction of speed dedusting
System is out sent into absorption cleaning system；
Step 3
When fluorinated volume in the gas come out from absorption cleaning system<10mg/m3And dustiness<0.15g/m3, then directly empty；
When fluorinated volume is more than or equal to 10mg/m in the gas come out from absorption cleaning system3Or dustiness is more than or equal to 0.15g/m3,
Then it is sent into purification dust removal system, carries out purifying and dedusting, until middle fluorinated volume in the gas from purification dust removal system out<
10mg/m3And dustiness<0.15g/m3。
A kind of 9. application process of the processing system of smoking gas containing fluorine according to claim 8；It is characterized in that：
Smoking gas containing fluorine flow velocity into first high speed adsorption column is 8m/s~15m/s, into the first middling speed adsorption column
Smoking gas containing fluorine flow velocity is 3m/s~10m/s, and the smoking gas containing fluorine flow velocity into first low speed adsorption column is：1m/s~5m/s.
A kind of 10. application process of the processing system of smoking gas containing fluorine according to claim 7；It is characterized in that：
The solute of lye used is alkali metal and/or dissolvable oxides, the alkali metal of alkaline-earth metal in the lye absorption tower
And/or the soluble hydroxide of alkaline-earth metal, the soluble carbonate salt of alkali metal and/or alkaline-earth metal, alkali metal and/or alkali
At least one of soluble bicarbonate of earth metal, concentration of lye are 0.5mol/L~3mol/L；In lye absorption tower
Lye enters tower mode and is selected from sidepiece atomizing, top-spray formula, and smoking gas containing fluorine enters from lye absorb the bottom of the tower；
When fluorinated volume is less than 10mg/m in the gas come out from absorption cleaning system3But dustiness is more than or equal to 0.15g/m3, then send
Enter in the dust catcher in purification dust removal system, carry out purifying and dedusting, until containing in the gas from purification dust removal system out
Fluorine amount<10mg/m3And dustiness<0.15g/m3；The dust catcher is bag filter.
