Comparative Study on Performance of Ring Suction Type and Slit Type Exhaust Hood for Oil Mist Capture in Aluminum Cold Rolling
In order to solve the problem of environmental pollution caused by a large amount of flue gas in cold rolling process,the physical models of annular suction hood and slit hood for oil mist trapping in aluminum rolling process are established.The numerical calculation model of the flow field of two kinds of exhaust hoods is established by means of computational fluid dynamics method,and the characteristic wind speed near the mouth of the two kinds of exhaust hoods and the trapping effect of pollutants are compared.The results show that the trap performance of annular suction hood is better than that of slit hood.
