Cement production method capable of reducing resistance of cement kiln
The invention relates to the technical field of cement production, in particular to a cement production method capable of reducing resistance of a cement kiln, which comprises the following steps: S1, downwards heightening a C2 cyclone volute by 1300mm; s2, a volute of the C3 cyclone cylinder is heightened downwards by 1300 mm; s3, a volute of the C4 cyclone cylinder is heightened downwards by 1300 mm; s4, a material scattering box is additionally arranged at an outlet of the cyclone cylinder C2; s5, an expansion joint with the diameter of 3.2 m is replaced at a smoke chamber necking down, and a vertical wall shell behind the smoke chamber is expanded outwards by 300 mm; s6, the coal injection pipe of the decomposing furnace moves downwards to the position above the necking; s7, the material scattering boxes C3, C4 and C5 of the cyclone uptake flues move downwards to be 1200mm away from the top of the cyclone uptake flues. According to the cement production method capable of reducing the resistance of the cement kiln, the residual air adding pipeline of the kiln head grate cooler is arranged to the hot air pipeline of the coal mill, the residual air temperature is utilized, the opening degree of a hot air valve from the grate cooler to the coal mill and cold air mixing are reduced, coal consumption is reduced, and the problems that resistance is reduced by changing the structure of a cyclone cylinder in the using process in the background technology; however, the coal consumption is high in the cement production process.
本发明涉及水泥生产技术领域，尤其涉及了一种可实现水泥窑降阻的水泥生产方法，包括以下步骤：S1：C2旋风筒蜗壳向下加高1300mm；S2：C3旋风筒蜗壳向下加高1300mm；S3：C4旋风筒蜗壳向下加高1300mm；S4：C2旋风筒出口增加撒料箱；S5：烟室缩口更换直径为3.2m膨胀节、烟室后面立墙壳体外扩300mm；S6：分解炉喷煤管下移至缩口上方；S7：撒料箱C3、C4和C5旋风筒上升烟道撒料箱往下移离顶部距离1200mm。该可实现水泥窑降阻的水泥生产方法，通过窑头篦冷机余风加装管道至煤磨热风管道，利用余风温度，减少篦冷机至煤磨热风阀开度及冷风掺入，降低煤耗，解决了背景技术中提出的在使用过程中通过改变旋风筒结构进行降阻，但是在对水泥生产过程中煤耗较大的问题。
