Novel method for firing ceramsite by using coal gangue and equipment system thereof
The invention relates to the technical field of ceramsite firing, in particular to a novel method for firing ceramsite with coal gangue and an equipment system thereof. The method for firing the ceramsite comprises the following steps: grinding coal gangue into powder, pelletizing, distributing, drying and dehydrating, preheating, igniting, self-roasting, roasting at high temperature, and cooling twice to obtain the ceramsite. The equipment system comprises a belt type sintering machine, a cover body, an air blower, a first induced draft fan, a second induced draft fan, a third induced draft fan, a fourth induced draft fan, a waste heat recovery system and a dust removal system. The high-strength ceramsite is prepared from the coal gangue, the problems of environment and land occupation caused by deposition and stacking of a large amount of the coal gangue are solved, waste can be turned into wealth, the ceramsite is applied to the building industry, the ecological environment is prevented from being destroyed due to mountain cutting and quarrying during stone production, and in the ceramsite firing process, the heat value of the coal gangue is reasonably utilized, so that the energy consumption is reduced. A reasonable sintering process is designed, the heat value of the coal gangue is utilized to the maximum extent, excess heat is subjected to waste heat recovery, and the production cost is reduced.
本发明涉及烧制陶粒技术领域，更具体的，是一种用煤矸石烧制陶粒的新方法及其设备系统。烧制陶粒的方法是将煤矸石经过磨粉、制球、布料、烘干脱水、预热、点火、自焙烧、高温焙烧、两次冷却制得陶粒。设备系统包括：带式烧结机、罩体、鼓风机、第一引风机、第二引风机、第三引风机、第四引风机、余热回收系统、除尘系统。本申请将煤矸石制得高强度的陶粒，不仅解决了煤矸石大量沉积堆放带来的环境和占地问题，还可以变废为宝，应用于建筑行业，不仅避免了生产石子开山采石而破坏生态环境，在烧制陶粒过程中，通过合理的利用煤矸石自有热值，设计合理烧结工艺，将煤矸石自有热值最大化利用，多余热量进行余热回收，降低生产成本。
