Environment-friendly ashing treatment process and device
The invention belongs to the technical field of sodium carbonate industrial waste utilization, and relates to an environment-friendly liming treatment process and device, and the process comprises the following steps: feeding calcined limestone into a liming machine for liming treatment; carrying out jigging sorting on impurities separated from the lime slaking machine to respectively obtain low-fire limestone and over-fire limestone; the low-fire limestone is dried by tail gas of a calcining furnace or tedded and aired, is doped into raw materials of the calcining furnace for secondary calcining, and is sent back to the ashing machine for ashing treatment; putting the fired limestone into the digestion pit for aging, so that the fired limestone is fully digested, and collecting the emulsion obtained after digestion into the emulsion at the outlet of the lime melting machine. The device comprises an ash melting machine, a jigging machine and a digestion pit. The technology and the device are simple in structure and convenient to operate, the returned sand discharged by the lime slaking machine can be thoroughly and efficiently treated and utilized, the utilization efficiency of limestone resources is greatly improved, and pollution of a traditional lime slaking technology to the environment is reduced.
本发明属于纯碱工业废料利用技术领域，涉及一种环保型化灰处理工艺及装置，工艺上包括如下步骤：将煅烧过的石灰石送入化灰机化灰处理；将化灰机中分离出来的杂质进行跳汰分选，分别得到欠火石灰石和过火石灰石；将欠火石灰石经煅烧炉尾气烘干或摊晒凉干，并掺入煅烧炉原料中进行二次煅烧后，重新送回化灰机进行化灰处理；将过火石灰石放入消解坑中进行陈伏，使过火石灰石得到充分消解，消解后得到的乳液汇流到化灰机出口的乳液中。装置上包括化灰机、跳汰机和消解坑。本发明工艺及装置结构简单，操作方便，能够将化灰机排出的返砂进行彻底、高效处理和利用，大大提高了石灰石资源的利用效率，并降低了传统化灰工艺对环境的污染。
