Simulation analysis of negative pressure taking method in lead battery plant

铅蓄电池厂房的负压取值,既涉及铅烟、铅尘等污染物向外部环境的泄漏风险,又影响到通风系统的能耗和投资。针对铅蓄电池厂房设计现状,结合实际的工程实例和相关行业规范,提出了一种具有实用性的计算方法,用于确定铅蓄电池厂房的负压取值范围。利用专业工程软件COMSOL模拟铅蓄电池厂房的室外压力场,并与理论计算结果进行对比分析。结果表明,该负压计算取值方法具有一定的可行性和合理性,可以有效地减少污染物的排放,提高厂房的环保性能,同时还能降低前期设计成本,具有显著的经济效益和环保价值。该方法可为铅蓄电池厂房的设计和优化提供便利及参考。

The magnitude of negative pressure in lead-storage battery plants poses risks of lead smoke,lead dust,and other pollutants leaking into the external environment,thereby impacting energy consumption and investment in ventilation systems.This paper addresses the absence of a scientifically sound method for calculating negative pressure in the design of lead-storage battery plants.Drawing on real-world engineering cases and pertinent industry standards,this study proposes a practical approach to determining negative pressure values in such facilities.Utilizing the professional engineering software COMSOL,this study conducted numerical simulations of the outdoor pressure field surrounding lead-storage battery plants,comparing and analyzing these results against theoretical calculations.The findings demonstrate the feasibility and rationality of the proposed calculation method,which effectively mitigates pollutant emissions,enhances plant environmental performance,and reduces preliminary design costs,thereby yielding significant economic and environmental benefits.This methodology offers valuable guidance for the design and optimization of lead-storage battery plants.
