Specific embodiment
A kind of casting exhaust treatment system provided in this embodiment, structure is as shown in Figure 1, include sequentially connected air inlet pipe
1, pollutant-removing system and exhaust pipe are sprayed, exhaust gas is entered in spray pollutant-removing system by air inlet pipe 1, is handled by spraying pollutant-removing system
It is discharged again by exhaust pipe to clean gas.
Air inlet pipe 1 is connected with exhaust fan 11 backwards to 2 one end of spray chamber with the wind, will be generated in casting process by exhaust fan 11
Exhaust gas is evacuated in spray chamber 2 with the wind, and is connected to and is sprayed on roof with the wind.Intake can be increased in this way, improve working efficiency.
Spray pollutant-removing system includes the spray chamber with the wind 2 set gradually, filtering spray chamber 3, contrary wind spray chamber 4, is sprayed with the wind
It drenches room 2 and is equipped with a spray tube 21 along its roof and side wall, No. one time spray tube 21 is equipped with several spray heads, a spray tube 21
In be equipped with NaOH alkalinity neutralizer, for neutralizing the acidic materials in exhaust gas, so that acidic materials be avoided to be discharged.And due to adopting
With the mode sprayed with the wind, the contact area with exhaust gas can be increased in this way, so that cleaning is more felt.And it once sprays
Neutralizer in pipe 21 can not only neutralize the acidic materials in exhaust gas, can also tentatively remove the impurity in exhaust gas.
2 bottom of spray chamber is connected to filtering spray chamber 3 with the wind, and is formed clearly in spray chamber 2 with the wind and filtering spray chamber 3
