B. the waste gas in the waste gas box filters and adsorbs metal and dust in the waste gas through an adsorption plate (5), and the filtered waste gas is blown by a fan (19) and guided into a UV photolysis chamber through an air outlet pipeline (3) for photolysis;
C. introducing the photolyzed gas into a combustion chamber and a fixed bed catalytic reactor for combustion and reaction;
D. and the reacted gas is treated by a waste gas purifier, then is introduced into water for secondary filtration and is discharged into the atmosphere.
8. The waste gas purification process for molten aluminum smelting processing as claimed in claim 7, wherein the air inlet pipeline (2), the box body (1) and the air outlet pipeline (3) are coated with anti-corrosion materials.
9. The process for purifying exhaust gas for molten aluminum smelting processing according to claim 7, wherein the gas inlet pipe (2) preheats the exhaust gas to 200-230 ℃.
10. The process for purifying exhaust gas for molten aluminum smelting processing according to claim 7, wherein the adsorption plate (5) comprises an annular plate (31) and an activated carbon filter screen (32), and the activated carbon filter screen (32) is fixedly embedded in the annular plate (31).
