Rotary cement kiln oxygen-enriched calcining device and rotary cement kiln oxygen-enriched calcining process
The invention provides a rotary cement kiln oxygen-enriched calcining device and a rotary cement kiln oxygen-enriched calcining process. The device is characterized in that, the air inlets of both a top coal air conveying Roots blower (8) and a tail coal air conveying Roots blower (9) in front of a rotary kiln (13) and a decomposing furnace (14) are hermetically connected with an oxygen-enriched air supply system by an oxygen-enriched air pipe (7). The process is characterized in that the rotary kiln (13) and the decomposing furnace (14) perform the air conveying of the coals by completely using the oxygen-enriched air blown by the oxygen-enriched air supply system by the top coal air conveying Roots blower (8) and the tail coal air conveying Roots blower (9) respectively; and the oxygen-enriched calcining is preformed at the same time in the rotary kiln (13) and the decomposing furnace (14). The calcining process of the device can be used for improving the temperature of flame in the kiln, the coals are burned completely, the coal consumption is reduced, and the effects of saving coals and reducing costs are achieved.
