发明内容
本发明的目的是针对现有技术存在的问题，提供一种吡啶及3-甲基吡啶制备过程的节能技术。
本发明采用的技术方案是：一种吡啶及3-甲基吡啶制备过程的节能技术，其特征在于：包括再生器，所述再生器与外旋风联通，所述外旋风下部联通催化剂罐，上部与废热炉联通，所述废热炉与软水罐联通，所述软水罐上部设有软化水进口和出口，软水罐出口与闪蒸罐联通，所述闪蒸罐设有疏水进口和蒸汽出口。
本发明有益效果：本方法在再生器内的排气口增加一个废热炉和一个软水罐，将热空气和软水换热，将会产生0.5Mpa的蒸汽，从而这些蒸汽可以给物料的伴热、储罐的盘管加热等使用，对热能回收利用，从而减低了热能消耗，大大降低产品成本。
附图说明
下面结合附图和具体实施方式对本发明做进一步说明。
附图为本发明工作原理示意框图。
具体实施方式
如图所示的一种吡啶及3-甲基吡啶制备过程的节能技术，其特征在于：由再生器产生600℃的空气，空气量为8000Kg/h经管道进入外旋风将空气中夹杂的催化剂粉末分离后进入催化剂罐，其余空气由外旋风上部排出进入废热炉，废热炉与软水罐联通给软水换热，进入废热炉的空气经换热后进行排空，软化水经软水罐换热后产生0.5Mpa的蒸汽，进入闪蒸罐，与来自各设备疏水在闪蒸罐内进行闪蒸，闪蒸出0.5Mpa，温度为150℃的蒸汽，一部分作为伴热用，另一部分给其他车间供汽。
