Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1-3, a fermentation waste gas collecting and treating device comprises an exhaust device, a waste gas treatment system 2 and a fan 3. The exhaust device comprises a main air duct 11 and a plurality of sets of three-way air valve assemblies 12, wherein each three-way air valve assembly 12 comprises a three-way air duct 121, a first branch air duct 122, a second branch air duct 123, a first air valve 124 and a second air valve 125. Three tuyeres of the three-way air pipe 121 are respectively connected with the exhaust end of the fermentation tank, the first branch air pipe 122 and the second branch air pipe 123.
