Municipal Solid Waste Incineration Fly Ash Solidification System

Introduction to the Fly Ash Solidification System

The fly ash solidification system is an environmental protection treatment technology used to convert fly ash produced during garbage incineration into harmless or low-harm solid waste, making it safe for storage, transportation, and final disposal. Below is a detailed introduction to the fly ash solidification system and related content:

(1) Waste-to-Energy Plant Fly Ash Solidification System

The fly ash solidification system in waste-to-energy plants consists of fly ash collection, storage, transportation, mixing, solidification forming, and curing, among other components. The system operates by collecting fly ash from the incineration plant's flue gas treatment system and transporting it to a storage silo, while cement and chemicals are also sent to their respective storage devices. These materials are mixed in accordance with the process ratio, passed through a measuring device and conveying device, and then mixed in the fly ash kneader. The mixed fly ash slurry is processed through a series of equipment to form cement products and undergoes curing. Once cured, the solidified product can be safely transported to a landfill for disposal. This system effectively solves the problem of fly ash treatment in waste-to-energy plants, achieving stabilization, reduction, and harmless treatment of fly ash.

System Features:

Achieves stabilization, reduction, and harmless treatment of fly ash.

Solves the difficulties of fly ash treatment and ensures environmental safety.

Improves the overall environmental protection level of waste-to-energy plants.

Automated system operation, reducing manual intervention and enhancing safety.

(2) Upgrade of Waste-to-Energy Plant Fly Ash Solidification System

The upgrade of the fly ash solidification system in waste-to-energy plants primarily focuses on improving treatment efficiency, reducing energy consumption, and enhancing system stability. The upgrade may include optimizing system layout, upgrading key equipment, and introducing intelligent control systems. Through these upgrades, the fly ash solidification process can be automated and intelligently controlled, improving treatment efficiency and quality while reducing operating costs and maintenance difficulty. For example, the introduction of a PLC control system for fully automated control, with formula combination and preservation functions, greatly enhances system flexibility and stability.

Upgrade Advantages:

Achieves automation and intelligent control.

(3) Fly Ash Secondary Chelation System

The fly ash secondary chelation system is a specialized equipment designed for the maintenance or treatment of unqualified fly ash in waste-to-energy plants. The system mainly consists of a bag-breaking system, crushing system, batching system, mixing system, and stabilizer solution supply system. The secondary chelation process involves breaking and crushing unqualified fly ash or blocky fly ash, followed by mixing with chelating agents and cement to form a stable solidified product. This system can effectively treat fly ash that was not properly treated in the first process or the coke and blocky fly ash cleaned during maintenance, ensuring that the stabilization of fly ash meets standard requirements.

System Advantages:

Efficient processing: Specifically designed for fly ash that was not properly treated initially, ensuring it meets environmental standards.

Wide adaptability: Suitable for treating coke and blocky fly ash cleaned during maintenance, improving processing flexibility.

Optimized resource utilization: Through secondary chelation, reduces the disposal volume of fly ash, maximizing resource utilization.

Automated operation: The system operates automatically, reducing manual intervention, and improving processing efficiency and safety.

Cost-effective: By optimizing the treatment process, reduces long-term operating costs, achieving a win-win for economic and environmental benefits.

(4) Comprehensive Solution for Fly Ash Resource Utilization

The comprehensive solution for fly ash resource utilization builds upon the solidification treatment of fly ash to further explore ways to utilize fly ash as a resource. Through scientific and reasonable treatment and utilization methods, fly ash is converted into valuable resources or products. For example, the solidified fly ash can be used as a building material or for backfilling, achieving resource reuse. Additionally, the useful components in fly ash can be extracted and recycled for the production of other products. This solution not only reduces the environmental harm of fly ash but also promotes the recycling of resources and the sustainable development of the economy.
