Problems solved by technology

Due to the uneven air distribution of the incinerator, the garbage often burns unevenly on the surface of the grate, that is, the flame is unevenly distributed on the surface of the grate, causing some garbage to go directly into the slag well without burning out, and this material The unevenness of layer combustion will expose part of the grate surface to the flame, which will damage the grate and reduce the service life of the grate

Embodiment 1

[0036] The invention provides a garbage incinerator, such as figure 2 As shown, the garbage incinerator of the present invention includes an oxygen generator 1, an oxygen air duct 2, an air chamber 3, a primary air inlet duct 4, an oxygen intake duct 5, an electric damper 6, a deflector 7, a camera 8, an incinerator Furnace 9 and hearth 10.

[0037] The garbage incinerator of the present invention will be further described below in conjunction with the accompanying drawings. The garbage incinerator of the present invention is zoned oxygen-enriched combustion, so that the garbage can be burned evenly on the grate, and the garbage can be fully burned, so that the garbage can be fully utilized. The thermal energy of the garbage can reduce the heat loss rate. In order to achieve the above purpose, the garbage incinerator of the present invention includes several independent air chambers located below the grate piece, and each independent air chamber is provided with The primary ...

Embodiment 2

[0054] The present invention also provides an incineration method of the garbage incinerator based on Embodiment 1, the method includes step S1: monitoring the flame position inside the garbage incinerator, and determining the grate pieces with uneven combustion conditions , and record and feed back the position of the air chamber corresponding to the grate piece;

[0055] Step S2: Open the electric damper of the oxygen intake pipe on the corresponding air chamber to increase the oxygen supply and improve the combustion condition.

[0056] Specifically, such as figure 2 , image 3 As shown, when uneven combustion occurs on the surface of the incinerator 9, when the flame does not spread to one or more areas on the incinerator with garbage material layers, or when it is necessary to increase the combustion effect of the material layer in one or more areas , the camera 8 records and feeds back the position of the oxygen content adjustment unit corresponding to the area. At th...

Abstract

The invention relates to a garbage incinerator and an incineration method. The garbage incinerator comprises a plurality of grate plates and further comprises a plurality of independent air chambers located below the grate plates, each independent air chamber is provided with a primary air inlet pipe and an oxygen inlet pipe, and each oxygen inlet pipe is further provided with an electric air door for controlling oxygen inlet. Through regulating an independent oxygen supply unit, garbage can be uniformly burnt on the grate, the garbage is burnt out completely, and accordingly the garbage heat energy is completely used, the thermal reduction rate is lowered, and the grate plate protection is realized.

Description

technical field [0001] The present invention relates to the field of domestic waste incineration power generation. Specifically, the present invention relates to a waste incinerator and an incineration method. More specifically, the present invention relates to a method and device for oxygen-enriched combustion in a district of a waste incinerator. The invention relates to a method and a device for uniformly burning a garbage material layer in a furnace with the oxygen content of combustion air in different air chambers. Background technique [0002] During the use of domestic waste incineration grate, the function of feeding grate is very critical, and its reliability directly affects the reliability of the entire incinerator and even the entire incineration power plant, thus affecting the domestic waste treatment capacity and economic benefits. [0003] Most of the existing waste incinerators use mechanical waste incinerators. figure 1 The shown garbage incinerator is ju...
