Comprehensive utilization scheme of carbide slag and boiler flue gas in sodium carbonate production
The invention relates to the field of chemical engineering, and discloses a comprehensive utilization scheme of carbide slag and boiler flue gas in soda ash production, the comprehensive utilization scheme comprises an ash melting machine, a lime bin and a carbide slag bin are arranged outside the ash melting machine, the lime bin and the carbide slag bin are respectively communicated with the ash melting machine through spiral feeding equipment, and a carbide slag elevator is arranged on the outer side of the carbide slag bin. An input port of the carbide slag elevator is communicated with the carbide slag hopper, an output port of the carbide slag elevator is positioned above the carbide slag bin, a lime milk sieve is arranged below a discharge port of the lime slaking machine, a lime milk barrel is arranged below the lime milk sieve, the lime milk barrel is connected with a lime milk pump, and an output pipe of the lime milk pump is communicated with the ammonia distillation system. According to the invention, the production load of the lime kiln can be reduced, the raw materials of limestone and coke can be saved, and the solid waste carbide slag generated by the PVC production device and the waste gas generated by the flue gas of the coal-fired boiler can be fully utilized.
本发明涉及化工领域，且公开了一种电石渣及锅炉烟气在纯碱生产中的综合利用方案，本发明包括化灰机，化灰机的外部具有石灰仓和电石渣仓，石灰仓和电石渣仓分别通过螺旋进料设备连通化灰机，电石渣仓的外侧具有电石渣提升机，电石渣提升机的输入端口连通电石渣料斗，电石渣提升机的输出端口位于电石渣仓的上方，化灰机的出料口下方具有石灰乳筛，石灰乳筛的下方具有灰乳桶，灰乳桶连接有灰乳泵，灰乳泵的输出管与蒸氨系统连通。本发明不仅可降低石灰窑的生产负荷，节省原材料石灰石和焦炭，还可以充分利用PVC生产装置产生的固废电石渣，以及燃煤锅炉烟气产生的废气。
