Detailed ways

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

This embodiment provides a high-efficiency garbage pyrolysis gasification incinerator based on the utility model. The overall structural schematic diagram of the incinerator refers to FIGS. 1 and 2. The incinerator includes: a furnace body 4 and is arranged on the furnace body 4 The wind supply device on the side; the wind supply device includes a glass observation hole 12, an electric valve 13 and a high-pressure wind blower 14, and the wind supply inlet 16 of the wind supply device is arranged on the furnace cover positioned at the upper end of the body of furnace 4 3, the supplementary air inlet 16 is connected to one end of the electric valve 13 through a pipeline, and the other end of the electric valve 13 is connected to the supplementary air high-pressure fan 14 through a pipeline. On the pipeline between the electric valves 13 and above the supplementary air inlet 16, a glass observation hole 12 is arranged, and the glass observation hole 12 and the supplementary air inlet 16 are in the same vertical direction and communicated by a pipeline.

The high-efficiency garbage pyrolysis gasification incinerator provided in this embodiment is provided with an air supply device. And the supplementary air inlet 16 of the supplementary air device is arranged on the furnace cover 3 . The air supply high-pressure blower 14 is used as the power for conveying wind, and the supply air high-pressure blower 14 is located outside the furnace body 4 . The flow rate of the air delivered by the air supply device is controlled by the electric valve 13 . The supplementary air inlet 16 and the electric valve 13 and between the electric valve 13 and the supplementary high-pressure blower 14 are respectively connected by pipelines.

The specific structure of the glass observation hole 12 is: a branch pipe can be divided on the pipe between the supplementary air inlet 16 and the electric valve 13, and the branch pipe is arranged directly above the supplementary air inlet 16. Glass and other transparent materials to seal.

By setting the glass observation hole 12, it is convenient to observe the flame condition in the furnace body 4, and it is convenient to monitor the combustion condition of the material in the furnace body 4 in real time so as to control and adjust the combustion condition, thereby ensuring the stability of the working condition.

By setting the supplementary air inlet 16 on the furnace cover 3, the supplementary wind is sent into the furnace body 4 from the top of the furnace body 4. On the one hand, fresh air is transported from the top of the furnace body 4 to the furnace body 4, which can Provide sufficient oxygen to the material located in the upper part of the furnace body 4 so that it can be fully burned, in case that when the air supply device is located at the bottom of the furnace body 4, the conveyed wind will be blocked by the material inside the furnace body 4. In the material reaching the upper part of the furnace body 4, the material is not fully burned, which affects the stability of operation. In addition, by feeding fresh air into the furnace body 4 for a second time, the furnace body 4 has more oxygen, which can also increase the material handling capacity of the incinerator and improve the incineration efficiency.

On the other hand, fresh air is conveyed in the body of heater 4 from the top of the body of heater 4, and the upper region in the body of heater 4 can also serve as a secondary combustion chamber. Because the materials inside the furnace body 4 will decompose combustible gases when heated, these combustible gases will rise to the top of the furnace body 4, and the temperature inside the furnace body 4 is relatively high.
