- Title:
- A Pilot Study on Low-temperature Sludge Drying Process Based on Double Air Duct and Large Air Volume
- 摘要:
- 针对含水率高或黏性大污泥干化效率低等问题,开展了市政污泥低温干化工艺中试研究,利用双风道大风量成型技术,验证低温干化设备运行的可靠性与适应性,探讨不同运行参数条件下对机组能效的影响。结果表明,该中试机组能够连续稳定运行,当干化温度为55~70 ℃时,污泥含水率从80%降低至30%以下,机组平均单位能耗除水量可达3.72 kg/(kW·h),处理湿污泥的能耗为192 kW·h/t。
- Abstract:
- Aiming at the low drying efficiency of sludge with high moisture content or high viscosity, a pilot study on municipal sludge low-temperature drying process was carried out. The reliability and adaptability of the low-temperature drying equipment was verified by using double air duct and large air volume technology, and the influence of different operating parameters on the energy efficiency of the unit was discussed. The pilot unit ran continuously and stably. When the drying temperature was between 55 ℃ and 70 ℃, the moisture content of the sludge was reduced from 80% to less than 30%. The average unit energy consumption of water removal reached 3.72 kg/(kW·h), and the energy consumption of wet sludge treatment was 192 kW·h/t.
