Abstract
The invention discloses a waste incineration generating set with a rotary kiln. A bucket loader grabs waste and puts the waste into a waste pipe conveyor, and the waste is conveyed into a waste feeding tank and flows into the rotary kiln. A suction fan sucks in contaminated air inside a waste bin, the contaminated air is blown into the waste pipe conveyor, the contaminated air enters an intake air cooler through a strainer after coming out, and the air is then blown into the rotary kiln to support combustion of the waste. A motor drives the rotary kiln to rotate on a support table, and the waste combusting in the rotary kiln moves down slowly. Fuel flame sprayed out of an air outlet of an air pipe ignites the waste in the rotary kiln. After the incinerated waste comes out of the rotary kiln, roasting residue flows out of a waste residue hole roasting residue. Dioxin and inflammable gases in smoke from the rotary kiln are removed by incinerating in a smoke incinerator, and then the smoke is used for combusting to heat a boiler. High-temperature high-pressure steam generated in the boiler is used to drive a steam generator to generate electricity. Waste heat is used to heat waste pipe conveyor, and accordingly the waste in the waste pipe conveyor is dried.
