(2)For the exhaust gas come out from cyclone separator after heat exchanger, temperature drops to 60-70 by original 210-240 DEG C ℃;

(3)Exhaust gas in heat exchanger in the feeding scrubbing tower of 1.0-3m/s and 3-6m/s respectively through vacuum pump and wind turbine to remove Oil in circulating gas fat and gas aldehyde and acids small-molecule substance;

(4)Exhaust gas after washed tower washing is further speeded up by wind turbine to 2-4m/s, is sent into kitchen sink, is further washed To remove the small-molecule substance that the acids gas in gas and other are insoluble in water;

(5)Workshop air after wind turbine accelerates, is washed after being sent with the speed of 3-6 m/s to scrubbing tower;

(6)The NaHCO3 aqueous solutions that washings in kitchen sink are 10-20 g/L;

The invention has the advantages that:

Advantage one:The present invention can be reduced by reasonably designing to noxious gas emission, reinforcement environment in butter production process It protects and realizes that the cleanly production of enterprise has very important significance, realize the processing of butter processing exhaust gas, reach It is discharged again after discharge standard.

Advantage two:The present invention can be discharged the solid particle in exhaust gas, together by reasonably designing exhaust-gas treatment module When temperature is cooled down, then gas is discharged to by certain speed in scrubbing tower, in order to gas in scrubbing tower preferably Processing.

Advantage three:It is gentle that the present invention by reasonably designing scrubbing tower, by the scrubbing tower can remove Oil in circulating gas fat Body aldehyde and acids small-molecule substance.

Advantage four:The present invention is by reasonably designing type washing sink, by the type washing sink further in gas Harmful substance is cleaned, the gas more cleanliness without any pollution for discharging it.

Advantage five:Clever structure of the present invention, easy to implement using simple, simple process, using effect is apparent, is suitble to push away It is wide to use.
