垃圾發(fā)電廠飛灰固化系統(tǒng)主要由飛灰收集、儲存、輸送、混合攪拌、固化成型及養(yǎng)護等部分組成。系統(tǒng)工作原理是將焚燒廠煙氣處理系統(tǒng)的飛灰收集后送入存儲倉，同時水泥、藥劑也送至相應(yīng)的儲存裝置中。這些材料按照工藝配比，通過計量裝置和輸送裝置送入飛灰混煉機中進行混煉處理。混煉后的飛灰漿體通過一系列設(shè)備制成水泥制品，并進行養(yǎng)護。養(yǎng)護完成后，形成的固化體可以安全地運輸?shù)教盥駨S進行填埋處理?。此系統(tǒng)有效解決了垃圾焚燒發(fā)電廠飛灰處理難題，實現(xiàn)了飛灰的穩(wěn)定化、減量化和無害化處理。
(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.

垃圾發(fā)電廠飛灰固化系統(tǒng)的改造升級主要圍繞提高處理效率、降低能耗、增強系統(tǒng)穩(wěn)定性等方面進行。改造內(nèi)容可能包括優(yōu)化系統(tǒng)布局、升級關(guān)鍵設(shè)備、引入智能化控制系統(tǒng)等。通過改造升級，可以實現(xiàn)飛灰固化過程的自動化、智能化控制，提高處理效率和質(zhì)量，同時降低運行成本和維護難度。例如，引入PLC控制系統(tǒng)實現(xiàn)全自動控制，并具備配方組合和保存功能，可以大大提高系統(tǒng)的靈活性和穩(wěn)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）飛灰二次螯合系統(tǒng) Secondary Chelation System for Fly Ash ?
飛灰二次螯合系統(tǒng)是針對垃圾焚燒發(fā)電廠檢修或處理不合格飛灰而設(shè)計的專門設(shè)備。該系統(tǒng)主要由破袋系統(tǒng)、粉碎系統(tǒng)、配料系統(tǒng)、混合攪拌系統(tǒng)、穩(wěn)定劑溶液供給系統(tǒng)等部分組成。二次螯合的過程是將不合格的飛灰或塊狀飛灰進行破碎、粉碎后，再與螯合劑、水泥等材料進行混合攪拌，形成穩(wěn)定的固化體。此系統(tǒng)可以有效處理第一次處理不合格的飛灰或檢修時清理出的焦塊及塊狀飛灰，確保飛灰的穩(wěn)定化處理達到標準要求?。
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.

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.
