In the rotary kiln body, and one end that the blast pipe is located inside the rotary kiln body is connected with cylindrical sleeve, the circle
Multiple burning through-holes are offered on the outer wall of cylindrical sleeve, the blast pipe is located at the connection institute of one end outside the rotary kiln body
State the first blower, the bottom of the coal bunker is connected with coal feeding pipe, and the coal feeding pipe connects the blast pipe, the feed pipe by
It is extended at the flue gas chamber in the rotary kiln body.
Further, the rotary kiln burner further includes having cooling cylinder, and the cooling cylinder is connected by the support base
The bottom of the rotary kiln body.
Further, escape pipe is connected at the top of the flue gas chamber, the escape pipe is connected with exhaust gas processing device, institute
It states and is provided with the second blower on escape pipe.
This rotary kiln burner can drive institute by the rotation of the gear when carrying out active lime calcining production
The rotation for stating rotary kiln body imports limestone powder into the rotary kiln body from the feed pipe, and first blower will help
Combustion air is passed through by the blast pipe, while the coal dust in the coal bunker is imported the blast pipe by the coal feeding pipe
In, coal dust enters in the cylindrical sleeve after mixing with combustion air, logical by multiple burnings on the cylindrical sleeve
Hole is burnt, can effective dispersed flame, to limestone powder carry out sufficiently firing decompose, improve contacting efficiency, another party
Face, the spiral guide sheet inside the rotary kiln body are able to extend revolution route of the limestone powder in rotary kiln body, extend and burn
At the time, to guarantee the abundant decomposition of limestone powder.
