Abstract
The dust is easily emitted from the Feed mills that cause a lot of complain from neighborhood. The smell of dust generated by feed mills was usually ammonia-based animal protein. In this study, we combined with odor treatment technology and cleaning equipment integrated into the system equipment, then add Pyroligneous Acid to remove the ammonia of feed mills fugitive dust and odor in the washing machine. According to preliminary test results show that the concentration of feed mills’ Granular material room were dust at of 119*103~356*103 PT/cm3, NH3 concentration at 0.48 ~ 2 ppm. The dust particle size at 0.2 to 12.5μm. The facility were divided into two parts. The first part was dust collector, it could collect dust effectively. The dust mainly existed near by Feed mills’ facilities, so we developed dust collection equipment to reduce indoor dust. The second part was washing-through processing tank. We added same proportion of Pyroligneous Acid in wash solution to decompose NH3 in the water. The results in our study show the Dust-cover exhaust gas inlet as measured dust concentration of about 112~141*103 PT/cm3, a clean air outlet is 12.7~26.9*103 PT/cm3, dust removal efficiency reached 77 to 89%; dust hood outlet measured NH3 concentration of 0.49 ~ 2ppm, after the exhaust gas purification by washing liquid, measured vent ammonia concentration of about 0 ~ 0.16 ppm, the removal efficiency of 92% to 100%. In this study, the dust and odor-removing device can effectively collect airborne dust and dust through adsorption-deodorizing treatment, then release and clean the air. It was not only improve the air quality of feed mills, but also reduce environmental pollution and production costs of manufacturers.
