Exploration of reconstruction of high-altitude large-diameter high temperature pipe in cement plant
The original 3.80 m waste gas pipeline of a foreign 60500 t/d clinker cement production line was connected to a high-temper-ature fan and a dust collector of the exhaust fan in the burning system.The pipeline had an unreasonable direction and small corners,resulting in poor ventilation and high system resistance.The article introduces the scope and difficulties of the renovation of the high-altitude large-diameter high-temperature pipeline,and analyzes in detail the selection of renovation plans based on the short renova-tion period and limited renovation space.After the renovation,the system resistance decreased by 600 Pa,the fan power consumption decreased by 1 kWh,and the output of clinker increased by 150 t/d.The renovation effect was good.
