Description

Technical Field

[0001] The present invention relates to the technical field of waste incineration, and more specifically to an intelligent system for real-time control of dioxins in a waste incineration process. Background Art

[0002] As a widely used method of waste disposal, waste incineration is based on the core principle of converting the combustible components in waste into ash and waste gas through a high-temperature oxidation process. In this process, although the volume of waste is greatly reduced and energy is recycled, it also brings about an environmental problem that cannot be ignored - the generation of dioxins. Dioxins, a highly persistent and extremely toxic organic pollutant, are mainly attributed to the complex reaction of chlorine and organic matter in waste. Under high-temperature incineration conditions, these components undergo a series of chemical reactions and eventually form this substance that poses a serious threat to human health and the environment. Therefore, how to effectively control the emission of dioxins during waste incineration has become a key issue that needs to be urgently addressed in the current environmental protection field.

[0003] At present, the existing waste incineration equipment has the following problems with the emission control of dioxins during waste incineration: When it is detected that dioxin emissions exceed the standard, the existing equipment often needs to take cumbersome measures to deal with it, such as adjusting the combustion conditions, adding inhibitors, etc. These measures are not only time-consuming and labor-intensive, but also have limited effects. Secondly, the existing flue gas control equipment is inefficient and has high energy consumption. When purifying flue gas through pyrolysis equipment, a large amount of energy is often consumed, and the purification efficiency is not ideal. In order to meet emission standards, enterprises have to invest high costs in equipment upgrades and operation and maintenance, which undoubtedly increases the economic burden of enterprises.

[0004] Existing flue gas control equipment has obvious deficiencies in treating dioxins. On the one hand, the purification efficiency of these devices is limited and they cannot effectively remove dioxins from flue gas. On the other hand, the energy consumption of pyrolysis equipment is high, which is not conducive to energy conservation, emission reduction and sustainable development. In summary, in view of the shortcomings and limitations of existing waste incineration equipment in the control of dioxin emissions, we propose an intelligent system for real-time control of dioxins in the waste incineration process.
