垃圾发电厂飞灰固化系统主要由飞灰收集、储存、输送、混合搅拌、固化成型及养护等部分组成。系统工作原理是将焚烧厂烟气处理系统的飞灰收集后送入存储仓，同时水泥、药剂也送至相应的储存装置中。这些材料按照工艺配比，通过计量装置和输送装置送入飞灰混炼机中进行混炼处理。混炼后的飞灰浆体通过一系列设备制成水泥制品，并进行养护。养护完成后，形成的固化体可以安全地运输到填埋厂进行填埋处理‌。此系统有效解决了垃圾焚烧发电厂飞灰处理难题，实现了飞灰的稳定化、减量化和无害化处理。

(1) Fly Ash Solidification System in Waste-to-Energy Plants 

The fly ash solidification system in waste-to-energy plants mainly consists of fly ash collection, storage, transportation, mixing and stirring, solidification and molding, and curing components. The system operates by collecting fly ash from the incinerator’s flue gas treatment system and conveying it to a storage silo, while cement and additives are also sent to their respective storage devices. These materials are proportioned according to the process recipe, measured, and conveyed into the fly ash mixing machine for mixing and blending. The blended fly ash slurry is then processed through a series of equipment to form cement products and undergoes curing. Once the curing is complete, the resulting solidified mass can be safely transported to a landfill for disposal. This system effectively addresses the challenge of fly ash treatment in waste-to-energy plants, achieving the stabilization, reduction, and harmless treatment of fly ash.

‌

垃圾发电厂飞灰固化系统的改造升级主要围绕提高处理效率、降低能耗、增强系统稳定性等方面进行。改造内容可能包括优化系统布局、升级关键设备、引入智能化控制系统等。通过改造升级，可以实现飞灰固化过程的自动化、智能化控制，提高处理效率和质量，同时降低运行成本和维护难度。例如，引入PLC控制系统实现全自动控制，并具备配方组合和保存功能，可以大大提高系统的灵活性和稳定性‌。

The retrofit and upgrade of the fly ash solidification system at waste-to-energy plants mainly focuses on improving processing efficiency, reducing energy consumption, and enhancing system stability. The retrofitting may include optimizing the system layout, upgrading key equipment, and introducing intelligent control systems. Through these upgrades, the fly ash solidification process can be automated and intelligently controlled, which boosts processing efficiency and quality while reducing operational costs and maintenance complexity. For example, the incorporation of a PLC control system for fully automated control, with features like formula combination and preservation, can greatly enhance the system’s flexibility and stability.

‌（3）飞灰二次螯合系统 Secondary Chelation System for Fly Ash ‌

飞灰二次螯合系统是针对垃圾焚烧发电厂检修或处理不合格飞灰而设计的专门设备。该系统主要由破袋系统、粉碎系统、配料系统、混合搅拌系统、稳定剂溶液供给系统等部分组成。二次螯合的过程是将不合格的飞灰或块状飞灰进行破碎、粉碎后，再与螯合剂、水泥等材料进行混合搅拌，形成稳定的固化体。此系统可以有效处理第一次处理不合格的飞灰或检修时清理出的焦块及块状飞灰，确保飞灰的稳定化处理达到标准要求‌。

The secondary chelation system for fly ash is a specialized equipment designed for the maintenance or treatment of unqualified fly ash in waste incineration power plants. The system mainly consists of a bag-breaking system, a crushing system, a batching system, a mixing and stirring system, and a stabilizer solution supply system. The process of secondary chelation involves breaking and crushing the unqualified fly ash or lump ash, followed by mixing and stirring with chelating agents, cement, and other materials to form a stable solidified body. This system can effectively treat fly ash that fails to meet the standards in the first treatment or the cinder and lump ash cleaned out during maintenance, ensuring that the stabilization of fly ash meets the standard requirements.

‌（4）飞灰资源化配套解决方案  Comprehensive Solution for the Resource Utilization of Fly Ash ‌

飞灰资源化配套解决方案是在飞灰固化处理的基础上，进一步探索飞灰的资源化利用途径。通过科学合理的处理和利用方式，将飞灰转化为有价值的资源或产品。例如，可以将固化后的飞灰作为建筑材料或填坑物料使用，实现资源的再利用。同时，也可以考虑将飞灰中的有用成分进行提取和回收，用于生产其他产品。此方案不仅可以减少飞灰对环境的危害，还可以实现资源的循环利用和经济的可持续发展‌。

The comprehensive solution for the resource utilization of fly ash builds upon the foundation of fly ash solidification treatment, further exploring ways to utilize fly ash as a resource. Through scientific and reasonable treatment and utilization methods, fly ash is transformed into valuable resources or products. For instance, the solidified fly ash can be used as a construction material or for land filling, achieving the reuse of resources. Additionally, the extraction and recovery of useful components from fly ash for the production of other products can be considered. This solution not only reduces the environmental harm caused by fly ash but also realizes the circular utilization of resources and the sustainable development of the economy.
