Recycling system for tail gas waste heat of calcining system
The invention discloses a recycling system for tail gas waste heat of a calcination system. The recycling system comprises a heat exchanger, an induced draft fan and a raw material bin. The heat exchanger comprises a waste gas channel and an air channel for exchanging heat energy, the waste gas channel is connected with calcining system tail gas, and the air channel is connected with atmosphere and the induced draft fan, so that air is heated into hot air through the heat exchanger; a spraying pipe is arranged in the raw material bin, the spraying pipe is close to the bottom of the raw material bin and connected with the air channel to spray hot air to the top of the raw material bin, the gypsum powder freely falls in the raw material bin, and free water in the gypsum powder is mixed with the hot air and then leaves the raw material bin through the air output end. By means of the recycling system, people use tail gas of the calcining system to heat fresh air in the atmosphere to 70-80 DEG C, hot air and gypsum powder are mixed to enable the content of free water in the gypsum powder to be stabilized to be 12% or below, meanwhile, the tail gas exhaust temperature of the calcining system is reduced to 50 DEG C from 110-120 DEG C, and therefore energy for stir-frying the calcined gypsum powder is saved.
本发明公开了一种煅烧系统尾气余热的再利用系统，包括：换热器、引风机和生料仓；换热器包括用于交换热能的废气通道和空气通道，废气通道连接煅烧系统尾气，空气通道连接大气和引风机，以使得空气经过换热器被加热为热空气；生料仓的内部设置有喷管，喷管靠近生料仓的底部，喷管连接空气通道以向生料仓的顶部喷射热空气，石膏粉在生料仓中自由落体，石膏粉中的游离水和热空气混合后通过空气输出端离开生料仓。通过再利用系统，人们使用煅烧系统尾气将大气中的新鲜空气加热至70℃‑80℃，热空气与石膏粉混合使得石膏粉中的游离水的含量稳定在12％以下，同时煅烧系统尾排温度从110℃‑120℃降低到了50℃，从而节约了用于炒制熟石膏粉的能源。
