Description
Technical field
The tertiary air valve plate belongs to the cement manufacture plant field, is specifically related to valve flashboard on a kind of new type nonaqueous cement production line tertiary air valve.
Background technology
In the new type nonaqueous cement production line system, rotary kiln and decomposing furnace are to control by the aperture of reducing of kiln tail and tertiary air valve plate to realize with the distribution of air quantity.The tertiary air valve plate is the large-scale metal construction flashboard that is welded by heat-resisting steel sheet and plate, the heat-resisting mould material of the surface casting of flashboard, be provided with in the metal construction flashboard and be used for flashboard refrigerative ventilation duct, it is a vitals of rotary system operation control, it mainly acts on the balance of using air quantity in air quantity and the decomposing furnace of using that is by tertiary air in the unlatching regulation and control rotary kiln of tertiary air valve, thereby regulate the state of combustion of decomposing furnace, and then regulate thermal technology's operating mode of cement clinker firing system.The tertiary air valve plate directly affects the operation factor and the cement quality of rotary kiln, therefore, very high reliability be arranged.The tertiary air that kiln tail decomposing furnace uses is a hot blast of sending into decomposing furnace from the cooling machine after extracting, and temperature is generally at 800 ℃～1100 ℃, the about 20～30m/s of wind speed.Belong to high temperature, high dust, and contain obnoxious flavoures such as SO2, C12,, cause the disorder of firing system operating mode, frequently change valve plate the main frame operation factor will be descended to making the tertiary air valve plate easily be corroded, damage.The bottom of tertiary air valve plate in actual the use comes off damage such as heat-resisting steel sheet and plate scaling loss, flashboard distortion phenomenon because refractory castable appears in contact high-temperature hot-air easily.The tertiary air valve plate damages the cement clinker firing system has been produced very big negative impact, the stuck air quantity that makes the tertiary air valve can't regulate tertiary air after the distortion of flashboard at first, bring very big difficulty for the operation of cement grog firing system, have a strong impact on the throughput of system, secondly after the heat-resisting steel sheet and plate scaling loss, the cooling air channel of flashboard opens wide, a large amount of cooling airs mixes in the tertiary air, the tertiary air wind-warm syndrome is descended, cause the decomposing furnace injecting coal quantity to strengthen, waste energy.
The fire-resistant pouring material of the cold surface of the tertiary air valve plate that generally uses at present is 60mm, and fire-resistant pouring material comes off easily, and heat-resisting steel sheet and plate is oxidized scaling loss in high-temperature gas, cooling air channel opening, flashboard distortion.Generally have only 4 months work-ing life, can't adapt to the cement clinker firing system time between overhaul greater than 6～10 months requirement, causes very big difficulty for the production of cement grog.
