The present invention provides a kind of sodium butyrate process for producing granula and its exhaust gas treating methods, the present invention relates to non-antibiotic feed additive for promoting growth preparation fields, the main preparation including butyric acid sodium raw materials, mixing, extrusion, granulation ball blast and drying, it is related to the processing method of the tail gas in preparing butyric acid sodium granules simultaneously, collect the tail gas that spray drying obtains, tail gas is passed through into heat exchanger, collects the heat in tail gas.Then tail gas after cooling is then passed through into two sections of moisture film aeration tower processing, the waste heat of cleaning tail gas is obtained through exchanging heat through heat exchanger, heat is compensated by collet to storage tank again, then remaining clean gas discharge, sodium butyrate process for producing granula of the invention is safe and simple, and controllability is good, environmental protection is reliable. |
