基于鼓泡流化床的污泥焚烧保护控制
- Title:
- Protection Control of Sludge Incineration Based on Bubbling Fluidized Bed
摘要:- 污泥焚烧作为目前污水处理厂后期产物污泥的一种主流处理工艺，可实现污泥最彻底的减量化。污泥焚烧工艺复杂，涉及人身、设备和环境等多方面的安全性，其焚烧系统的保护控制尤为重要。以白龙港污泥处理处置二期工程鼓泡流化床污泥焚烧炉的保护控制为研究对象，对其主要的保护控制进行分析和总结，建立了几大保护逻辑关系，提出了合理的保护控制优化建议，并通过调试来验证相关保护定值的合理性，以期提高污泥焚烧系统的运行安全性和可靠性。
Abstract:- Incineration is wildly used for treating sewage sludge because of its considerable reduction in volume. Sludge incineration is complex and involves the safety of equipment, life, and also environment, which make the protection control of the incineration system especially important. The protection control of the bubbling fluidized bed (BFB) boiler in Bailonggang sludge treatment and disposal phase Ⅱ project is introduced including analysis of the protection control principle, establishment of serval logic relationship and proposal of some reasonable suggestions. Meanwhile, the reasonability of default values was verified by commissioning, so as to improve the safety and reliability of the sludge incineration system.
