Pulping and papermaking alkali recovery powdery quicklime digestion production process and device
The invention relates to the technical field of pulping and papermaking, in particular to a pulping and papermaking alkali recovery quicklime digestion production process and device which comprises a material leading device, a lime bin, a metering spiral conveyor and a lime digestion slag extractor. An outlet of the material leading device is connected with an inlet of the lime bin, a decompression cone is arranged at the bottom of the lime bin, a buffer tank is arranged below the decompression cone, the lower end of the buffer tank is connected with an inlet of a metering spiral conveyor, and an outlet of the metering spiral conveyor is connected with an inlet of a lime slaking slag extractor. Compared with the prior art, pneumatic conveying and bin entering are adopted, airtightness is good, self-digestion loss caused by much raised dust and quick lime stacking in the conveying process is avoided, and meanwhile the quick lime transfer efficiency is high, energy consumption is low and the conveying speed is high due to the design of the material leading device.
本发明涉及制浆造纸技术领域，特别涉及一种制浆造纸碱回收生石灰消化生产工艺及装置，包括引料器、石灰仓、计量螺旋输送器以及石灰消化提渣机；所述引料器的出口与所述石灰仓进口相连，所述石灰仓的底部设置有减压锥，所述减压锥下方设置缓冲罐，所述缓冲罐下端连接一计量螺旋输送器的进口，所述计量螺旋输送器的出口与一石灰消化提渣机的进口相连。与现有技术相比，本发明采用气力输送进仓，密闭性好，避免了输送过程扬尘多，生石灰堆置带来的自消化损耗，同时引料器的设计使生石灰的转运效率高，能耗低，输送速度快。
