Contracting, so that second partition 13 be pushed to move up and down, during second partition 13 moves up, cooperation first partition 12 squeezes retractable sack
14, spray sodium hydroxide solution in retractable sack 14 by atomizer 15, it, can be directly and after atomization after exhaust gas enters in device
Sodium hydroxide solution contact when second partition 13 moves down, pull retractable sack 14, make first to be purified to exhaust gas
Sodium hydroxide solution between partition 12 and second partition 13 enters in retractable sack 14, supplements sodium hydroxide solution in retractable sack 14
Consumption, due to exhaust gas constantly be passed through, 12 upper space air pressure of first partition rise, since sulfur-bearing class exhaust gas is more empty in exhaust gas
Makings amount is larger, and the exhaust gas after tentatively evolving is made to float, and the gas after tentatively evolving is made to pass through the first tracheae 16 and the second tracheae
17 enter in sodium hydroxide solution, and purified exhaust gas is discharged by escape pipe 18, when second partition 13 moves up, extruding gasbag 2,
To make stripper plate 23 move up, enter photocatalyst in 23 the first cavity 22 of top of stripper plate in conduit 21, and spray by spray gun
Out, ultraviolet radiator starts simultaneously with electric pushrod 11, and atomizer 15 and spray gun spray sodium hydroxide solution and light touching respectively
After matchmaker, exhaust gas, due to 12 upper surface arch design of first partition, extra sodium hydroxide solution and photocatalyst through hole stream are purified
Enter in storing ring 3, and through hole enters the space between first partition 12 and second partition 13, mixes with sodium hydroxide solution,
After 12 surface sodium hydroxide solution of first partition and photocatalyst flow into storing ring 3, floating block 31 floats, sodium hydroxide solution and light touching
It, can be effective by the filtering of floating block 31 into space between first partition 12 and second partition 13 after matchmaker is filtered by floating block 31
By the particulate contaminant filtering in exhaust gas, while the particulate matter under filtering can be taken out by material taking mouth, sodium hydroxide solution is logical
After the ejection of atomizer 15 and photocatalyst are crossed by spray gun ejection, the exhaust gas in 12 upper space of first partition is purified,
Part sodium hydroxide solution and photocatalyst are attached to 4 surface of filter plate, can be further to will enter the first gas by filter plate 4
Exhaust gas in pipe 16 and the second tracheae 17 further purifies, and the first tracheae 16 passes through filter plate 4, it is ensured that enters the first tracheae
Gas in 16 passes through multiple purifying, and prevents particulate matter from entering in the first tracheae 16, sodium hydroxide solution and photocatalyst point
Not Tong Guo atomizer 15 and spray gun when spraying, water suction cotton 42 absorbs sodium hydroxide solution and photocatalyst, exhaust gas pass through outlet
During hole 41, water suction cotton 42 is driven to shake, filter plate 4 is hit by the shake for the cotton 42 that absorbs water, shakes filter plate 4,
The gas discharged in waste gas purification apparatus is passed through in aerobic tank again after being passed through anaerobic pond, and the anaerobic bacteria in anaerobic pond will be in exhaust gas
Organic matter just decompose, the aerobic bacteria in aerobic tank by exhaust gas organic matter further progress decompose；It will pass through aerobic
The exhaust gas discharged in pond is passed through in alkaline solution, can be emitted into atmosphere by the exhaust gas of alkaline solution.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the above embodiments and description only describe originals of the invention
Reason, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes and improvements
It all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent circle
It is fixed.
