AI Technical Summary

Technical Problem

In existing waste incineration processes, the front-end pollution source blocking is not precise, thorough, or stable, making it difficult to effectively control dioxin and heavy metal emissions during incineration, and resulting in low resource utilization efficiency.

Method used

The system employs an intelligent control center-driven pollution source identification and separation system, which combines multiple physical sorting and comprehensive reagent pretreatment to achieve precise sorting and blocking of pollution sources such as plastics, batteries, metals, and electronic components. Through humidity control and high-voltage electrostatic sorting technologies, combined with online pollution monitoring and feedback mechanisms, a closed-loop control is formed.

Benefits of technology

It achieves precise and complete blocking of pollution sources at the front end of waste incineration, reducing dioxin generation by 95%, heavy metal emissions by 80%, SO2 emissions by 80%-85%, NOx emissions by 40%, operating costs by 50%, equipment lifespan by 3 years, and resource recycling efficiency by 12%.

Abstract

The application discloses a garbage incineration front-end pollution source blocking and recycling method, which is characterized by the following steps: S1, pollution source component identification and separation; S2, humidity regulation; S3, multiple physical separation; S4, pollution monitoring and feedback; and S5, comprehensive reaction agent pretreatment. The resource recycling treatment refers to plastic cleaning and granulation, metal magnetic separation and electronic component thermal separation of the screened pollution source components. The application can precisely, completely and controllably block the front-end pollution source before garbage incineration, and can realize stable treatment in the front-end treatment process and the subsequent incineration process, so as to eliminate the adverse effects caused by residual pollutants in the garbage incineration process.
