Detailed Description
Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
As shown in the figure, the air preheating device of the incinerator comprises a first preheater 1, a second preheater 2, a first air fan 3 and a second air fan 4, wherein the upper parts of the first preheater 1 and the second preheater 2 are connected through two pipelines, the inlet of the lower part of the second preheater 2 is connected to the outlet of a steam heater 5, and the inlet of the steam heater 5 is respectively connected to the first air fan 3 and the second air fan 4 through pipelines.
The top inlet of the steam heater 5 is communicated with a saturated steam pipeline 53, and the bottom outlet of the steam heater 5 is connected to a sewage pipeline 51 and a deaerator pipeline 52.
And the outlet at the bottom of the second preheater 2 is communicated to a furnace gas purification section through a pipeline.
The inlet at the bottom of the first preheater 1 is communicated to the incinerator through a pipeline, and the outlet at the bottom of the first preheater 1 is communicated to the oxygen supply part of the incinerator through a pipeline.
The upper communication pipeline of the first preheater 1 and the second preheater 2 leads from the first preheater 1 to the second preheater 2, and the lower communication pipeline leads from the second preheater 2 to the first preheater 1.
