Abstract: In order to separate semi coke and gas ，this paper has designed a single factor variable test on performance of horizontal cyclone separator with single discharge pipe. The effects of key structural parameters (diameter of discharge pipe D4, angle between exhaust pipe and discharge pipe β, length of guide body L4) on performance indexes (separation efficiency η, air leakage rate δ, pressure drop ΔP1 between inlet and discharge pipe of separator, pressure drop ΔP2 between inlet and exhaust pipe of separator) were investigated. The results show that when D4 increases from 60 mm to 80 mm, η changes from 94.9% to 95.6%. δ and ΔP1 increase gradually with D4. When β is 55°, η reaches the maximum. As β increases, δ changes little. ΔP1 and ΔP2 reach the maximum when β is 50°. When L4 is 300 mm, η、 ΔP1 and ΔP2 reach the minimum. δ changes with L4 by 2% under load condition.

Keywords: horizontal cyclone; pressure loss; separation efficiency; air leak rate
