Large-particle calcium oxide suspension calcination process
The invention belongs to the technical field of lime production, and particularly relates to a large-particle calcium oxide suspension calcination process. A device used in the process comprises a preheating part, a calcining part, a cooling part, an auxiliary pressurizing and heating part, a conventional fan, a storage bin and a feeding bin, wherein suspension air pipe of a second preheating hopper serves as a discharging port of the feeding bin and is connected to an air return pipe of a first preheating hopper; a suspension air pipe of the first preheating hopper serves as an exhaust pipe of a suspension calcining device, and a discharging pipe of the first preheating hopper is connected to an air return pipe of a second preheating hopper and a suspension air pipe of a third preheating hopper; and the discharging pipe of the second preheating hopper is connected to an air return pipe of the third preheating hopper and suspension air pipe of the fourth preheating hopper. According to the invention, a high-temperature and high-pressure fan and a pre-combustion bin assist in temperature increasing and pressure increasing, so the situation that a temperature is not enough when limestone powder is decomposed is avoided, meanwhile, the problem that the limestone powder cannot suspend due to small air pressure is also avoided, convenience is brought to work of workers, and the work and life of people are facilitated.
本发明属于石灰生产技术领域，尤其为大颗粒氧化钙悬浮煅烧工艺，包括预热部分、煅烧部分、冷却部分、辅助加压加温部分、常规风机、储料仓和进料仓，所述第二预热斗的悬浮风管作为加料仓的出料口，并连接至所述第一预热斗的回风管，第一预热斗的悬浮风管作为悬浮煅烧装置的排气管，第一预热斗的出料管连接至所述第二预热斗的回风管及第三预热斗的悬浮风管，第二预热斗的出料管连接至所述第三预热斗的回风管及第四预热斗的悬浮风管，由高温高压风机和预燃仓辅助增温增压，避免了在对石灰石粉进行分解时出现温度不够的情况，同时也避免了因风压较小导致石灰石粉不能悬浮的问题，给工作人员的工作带来便利，方便了人们的工作和生活。
