基于仿真模拟地埋式污水厂除臭通风系统的研究

摘要:

地埋式污水厂较传统污水厂除臭系统及通风系统的能力要求更高。本文研究了除臭通风系统风量计算方法,结合除臭系统设计、通风系统设计及仿真模拟,避免在设计和运行时造成浪费。提出高效的、精准化的通风收集系统设计思路,以某地埋式污水厂污泥脱水间为例,采用计算流体力学(CFD)模型进行模拟优化。提出运行控制对策,同时满足除臭通风效果安全、设备安全、节能降耗,提高能源利用效率。

Abstract:

Buried sewage plants have higher requirements for the capacity of deodorization systems and ventilation systems than above-ground sewage plants. This paper studies the air volume calculation method of deodorization ventilation system, combining deodorization system design, ventilation system design and simulation to avoid a certain degree of waste in the design. Put forward an efficient and accurate design idea of ventilation collection system, taking a sludge dewatering room of a buried sewage plant as an example, using computational fluid dynamics (CFD) model for simulation and optimization. Propose the operation control countermeasures for the deodorization ventilation system of the buried sewage plant, and at the same time satisfy the safety of deodorization ventilation effect, equipment safety, energy saving and consumption reduction, and improvement of energy utilization efficiency.
