Application and Analysis of Microbial Spray Filtering in Environmental Exhaust Gas Treatment

Due to a number of circumstances, grain depots will emit exhaust gases that are harmful to the environment and the health of the surrounding population in addition to being complex in composition and challenging to manage. In order to cope with environmental exhaust gases, this work integrates microbial spray filtering with an exhaust gas treatment equipment. The authors ran simulations of the mixture of exhaust gases and the microbial solution using COMSOL Multiphysics at various pipe diameters, initial nozzle distances, nozzle number, and nozzle intervals. The findings indicate that the pipe diameter should be 300mm, the starting nozzle distance should be 290mm, there should be five nozzles, and the nozzle interval should be 200mm to obtain the optimal mixing of exhaust gases and the microbial solution. The study offers a useful guide for microbial deodorization.
