Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] like figure 1 As shown, the self-adaptive control method for the oxygen content of the waste incinerator according to the embodiment of the present invention, according to the content of carbon monoxide and nitrogen oxides in the flue gas emission index of the waste incinerator in the production process, there is a certain negative correlation (that is, when the carbon monoxide is high, the nitrogen Oxide is low, when nitrogen oxide is high, carbon monoxide is low; and the two values ​​are closely related to the boiler oxygen setting) this characteristic, the oxygen content is adjusted, specifically including the steps:

[0027] S01. Obtain the carbon monoxide and nitrogen oxide contents in the flue gas emitted from the waste incinerator;

[0028] S02. Adjust the oxygen amount of the waste incinerator according to the carbon monoxide an...

Abstract

The invention discloses a self-adaptive control method and system for the oxygen content of a garbage incinerator, belongs to the technical field of garbage incinerators, and is used for solving the technical problems that the oxygen content of an existing garbage incinerator is not accurately adjusted, and the like. The method comprises the steps that S01, the content of carbon monoxide and the content of nitric oxide in flue gas discharged by the garbage incinerator are obtained; and S02, the oxygen content of the garbage incinerator is adjusted according to the content of the carbon monoxide and the content of the nitric oxide so as to adapt to different fuel working conditions. The device has the advantages of high automation degree, high oxygen amount adjusting precision and the like.

Description

technical field [0001] The invention mainly relates to the technical field of garbage incinerators, in particular to a method and system for self-adaptive control of the oxygen content of garbage incinerators. Background technique [0002] With the country's emphasis on environmental protection, incineration power generation, as a mature technology for the harmless treatment of municipal solid waste, has been widely used throughout the country. The layer combustion process of garbage on the grate is essentially the process of violent oxidation of garbage after drying. The oxygen supply in the incinerator is one of the decisive factors for the combustion status of garbage. Municipal solid waste is different from conventional fuels in that it has the characteristics of large fluctuations in components, high moisture content, low calorific value and instability of combustibles. Therefore, it is difficult to stabilize the output of waste heat boilers for waste incineration. In...
