Low-carbon environment-friendly coal gangue suspension calcination method and process system
The invention belongs to the technical field of coal gangue production, and particularly relates to a low-carbon environment-friendly coal gangue suspension calcination method and process system.The low-carbon environment-friendly coal gangue suspension calcination method comprises the following steps that firstly, coal gangue is subjected to suspension calcination, a multi-layer-distributed porous medium combustor is adopted in a calcining furnace, medium-low-heat-value gas fuel is combusted, and the coal gangue is obtained; 180-220 DEG C hot air which is discharged from the second cooling system and passes through a dust collector B is used as primary combustion-supporting air; the retention time of the gas in the calcining furnace system is less than 7 seconds, the O2 content in the flue gas at the outlet of the calcining furnace is controlled to be less than 2.0%, and the CO content is 3,000-8,000 ppm. According to the low-carbon and environment-friendly coal gangue suspension calcination method and process system, a multi-layer distributed porous medium combustor is adopted in a calcination furnace, low-heating-value gas can be combusted, and the problems that combustion in the calcination furnace is unstable, and temperature distribution is uneven are solved.
本发明属于煤矸石生产技术领域，尤其涉及一种低碳环保煤矸石悬浮煅烧方法及工艺系统，所述低碳环保煤矸石悬浮煅烧方法包括以下步骤：步骤一：将煤矸石悬浮煅烧，煅烧炉采用多层分布的多孔介质燃烧器，燃烧中低热值气体燃料，采用第二冷却系统出来经过收尘器B的180‑220℃的热风当一次助燃风；煅烧炉系统内气体停留时间小于7s，控制煅烧炉出口烟气中O2含量小于2.0％，CO含量为3000‑8000ppm。本发明提供一种低碳环保的煤矸石悬浮煅烧方法及工艺系统，煅烧炉采用多层分布的多孔介质燃烧器，可以燃烧低热值气体，解决煅烧炉内燃烧不稳定，温度分布不均难题。
