en with operators, experience judgment will not be discovered. Currently used flap valve unloader device, in order to prevent and smooth unloading, often allows certain by turning the volume in leak into the next makings tube, so adopt flap valve unloading may not fundamentally eliminate air leakage within. Research on a whirlwind tube leakage separation efficiency, looking for the influence of the effective measures to reduce the harm of fly ash, reduce the quantity and improve efficiency of the preheater kiln system has important significance. Next feed tube place from air leakage points whirlwind canister unloading mouth closer, air leakage caused a whirlwind of mono reduction separation efficiency is larger. In the actual production process, the flap valve unloading cannot pletely prevent leakage within. Appropriate extension with a whirlwind flap valve installation position cartridge unloading mouth, can increase the distance between the whirlwind canister separation efficiency. 2, the influence of whirlwind tube import wind speed Different wind conditions, with imported whirlwind tube import wind speed increase, next makings pipe leakage caused a whirlwind tube in reduction of separation efficiency increase, if keep constant, the air leakage of air leakage caused by imported wind speed reduction and separation efficiency whirlwind canister less effect. 3 and solid gas ratio influence Solid/gas ratio under different in feed tube and air leakage caused a whirlwind canister reduction separation efficiency is different also with solid/gas ratio increases, down feed tube leakage caused a whirlwind tube in reduction of separation efficiency 5 increases at the same time. But, for a given leakage rate, with solid/gas ratio increases, the difference in value and separation efficiency gradually narrowing. The greater the solid/gas ratio, feed tube place air leakage caused a whirlwind tube material unloading mouth place more serious phenomenon also shed. This may be solid/gas ratio in the next feed tube and air leakage caused a whirlwind canister the separation efficiency of the reduction of reason. 4, a whirlwind canister influence of the structure of 2 Whirlwind cylinder is generally rectangles 2 structure, a new type of lowpressure loss due to the structure type whirlwind tube changes and geometrical shape of 2 also change, some use fivesides, some use diamond, aims to guide into a whirlwind of mono under gassolid flow deflection movement, reduce a whirlwind canister resistance. Whirlwind tube import way generally has two kinds, namely import airflow tillu tangent says straight with cylinder type。 Airflow around the tangent says with spiral type cylinder. Due to import can make spiral into a whirlwind of cylinder, air passage gradually narrowed to help to reduce the distance of inner particles move, the distance to increase airflow exhaust, avoid short circuit, can improve the separation efficiency. But also has a deal with pressure loss of air, the advantages of small, reason often used. 5, tube insertion depth The increase of steelflue insert depth, the resistance coefficient and separation efficiency is the increase of different processes. Insert depth, and imported high tube ratio of s/a = o. range, low resistance coefficient little change, and separation efficiency increases slightly, so sure of separation efficiency should be emphasized the intermediate level resistance reduction whirlwind cylinder should be in s/a or so, and had better not amp。 lt。 Separation efficiency (too much), also don39。 t reduce ofamp。 gt。 (resistance coefficient increases too big)。 But the separation efficiency emphasized at the next higher level shall be s/a whirlwind tube in left and right sides, because when s/a When separation efficiency, reduce more when s/a separation efficiency increase when. 6 and the influence of tube diameter With the expansion of inner cylinder diameters, the resistance coefficient and separation efficiency of different diameter reduced, including D d/a cylinder。 2/3, 6 drag coefficient falling fast,。
