Fixed storage hopper, feeding system and calcining method of gas-burning double-hearth lime kiln
The invention discloses fixed storage hoppers, a feeding system and a calcining method of a gas-burning double-hearth lime kiln. The gas-burning double-hearth lime kiln comprises a kiln top receiving hopper, two kiln top fixed storage hoppers and a three-way valve for connecting the receiving hopper and the storage hoppers, a discharge valve is arranged at the lower end of each storage hopper; the two storage hoppers are arranged in a herringbone shape; discharge valves of the two storage hoppers are aligned to a feed port at the top of the kiln; the feeding direction is controlled through the three-way valve, and the two storage hoppers are fed alternately and circularly. The system is simple in structure and free of excessive additional mechanical parts, the electro-hydraulic three-way valve is adopted to switch the feeding channel, the storage hopper above is filled with materials in real time, the reversing period is short, and the service life of equipment is effectively prolonged. According to the system and the method, the pressure of a connecting channel of the lime kiln, the waste gas amount in the kiln, the lime energy consumption and the ash deposition and nodulation in the kiln are effectively reduced, the productivity of the lime kiln is improved, the service life of refractory materials of the lime kiln is effectively prolonged, and meanwhile, the design productivity of the whole lime kiln is also improved.
本发明公开了一种气烧双膛石灰窑固定式储料斗、加料系统及煅烧方法，包括窑顶受料斗1个，窑顶固定式储料斗2个，连接受料斗和储料斗的三通阀1个；每个储料斗的下端各设置1个卸料阀；两个储料斗呈“人”字形状排布；两个储料斗的卸料阀对准窑顶的进料口设置；通过三通阀控制加料方向，交替循环向两个储料斗中加料。该系统结构简单，没有过多的附加机械零部件，采用电液动三通阀切换加料通道，实时将上方储料斗加满料，换向周期少，有效延长了设备的使用寿命。该系统及方法有效降低石灰窑的连接通道压力，降低窑内废气量，降低石灰能耗，减少窑内积灰结瘤，提高石灰窑的生产率，有效延长石灰窑的耐材使用寿命，同时也提高整个石灰窑的设计产能。
