Detailed Description
Example, see figure 1: system for VOCs and peculiar smell in processing waste gas includes: the inlet end is connected to the alkaline tower 10 of this processing waste gas air supply, and the inlet end is connected to the acid cleaning tower 20 of the end of giving vent to anger of this alkaline tower 10, and the inlet end is connected to the advanced oxidation device 30 of the end of giving vent to anger of this acid cleaning tower 20, and the inlet end is connected to the plasma burner 40 of the end of giving vent to anger of this advanced oxidation device 30, and the inlet end is connected to the fan 50 of the end of giving vent to anger of this plasma burner 40. The outlet end of the fan 50 is connected to the atmosphere. That is, under the suction of the fan 50, the process exhaust gas sequentially flows through the alkaline tower 10 and the acid tower 20 to remove inorganic pollutants and dust, to reduce the subsequent treatment load, flows through the advanced oxidation apparatus 30 to remove most of the VOCs, flows through the plasma combustion apparatus 40 to remove the remaining VOCs and odors, and finally, the exhaust gas reaching the standard and having no odor is directly discharged to the atmosphere.
Wherein:
the caustic tower 10 can be a packed tower, a plate tower or a spray tower; the acid wash column 20 may also be a packed column, a tray column, or a spray column. In practical use, the exhaust gas passes through the alkaline tower 10 and then the acid tower 20, and the alkaline tower 10 and the acid tower 20 both adopt plate towers, so that the effect is best, and especially, the odor is eliminated more efficiently and thoroughly aiming at the malodorous harmful gas generated in the processing production of processing factories such as fish meal, meat and bone meal and the like.
