Detailed Description

The following examples are given for the purpose of illustrating the present invention, and the detailed embodiments and specific procedures are given for the implementation of the present invention, but the scope of the present invention is not limited to the following examples.

A combined garbage incinerator comprises a feeding mechanism 1, an incinerator 5 and a slag conveying mechanism 8. The left side of the incinerator is provided with a feeding mechanism which is equivalent to a garbage pretreatment mechanism, the uppermost end of the feeding mechanism is connected with a garbage feeding port, the middle part of the feeding mechanism is provided with an air supply pipeline 13, and the leftmost end section of the air supply pipeline is respectively connected with a motor 11 and an air heater 12 and used for controlling the rotation of the air supply pipeline and supplying air. The incinerator is comprised of a bottom incineration zone and an upper fly ash collection zone 55, a flue gas treatment zone 54 and a heat recovery zone 53. The slag conveying mechanism consists of a slag loading vehicle 82, a conveyor belt 83, a strong magnetic device 84, a slag recovery bin 85 and an iron slag recovery bin 86.

When the processed garbage has high water content and is not uniformly mixed, the flange 3 of the discharge port of the feeding mechanism is connected with the flange 4 of the feed port of the incinerator through the fastening bolt 2, the motor 11 and the air heater 12 are started, the garbage enters from the feed port of the feeding mechanism 1, and the stirring blades 16 on the air outlet pipeline 13 stir and crush the garbage, so that the garbage is uniformly mixed. Meanwhile, the air outlet 14 on the air outlet pipeline and the heating sheet 17 at the top of the feeding mechanism dry the garbage, so that the moisture of the garbage is removed, and the incineration efficiency of the incinerator is improved. The leachate recovery device 15 collects and treats the landfill leachate. The pretreated garbage enters from the incinerator feeding port 51 and is mixed and combusted with coal which enters the incineration area from the cinder feeding port 56 in advance, fly ash, smoke and heat generated in the incineration process are treated and recovered through a fly ash collecting area 55, a smoke treatment area 54 and a heat recovery area 53 respectively, and the first air supply port 6 and the second air supply port 7 supply air to the incinerator in a coordinated mode in the whole incineration process, so that the normal operation of the incineration process is guaranteed, and meanwhile, the generation amount of pollution gas is reduced.
