过滤器容尘过程对房间负压、风量的影响研究
Influence of filter dust holding process on room negative pressure and ventilation rate
摘要：
以某工程固化线通风系统为例,利用FLoMASTER软件建立了固化线排风管网一维水力平衡模型。根据过滤器容尘过程中的阻力特性曲线,模拟分析了固化线房间负压和风量随容尘量的变化。针对容尘过程中造成的固化线房间负压、风量不满足规范和设计要求的情况,提出了相应的调节措施,为后续调试和运行提供依据。
Abstract：
Taking the ventilation system of a curing line of a project as an example, the one-dimensional hydraulic balance model of the curing line exhaust pipe network is established by using the FLoMASTER software. The change of negative pressure and ventilation rate of the curing line room with the dust holding volume is simulated and analysed according to the resistance characteristic curve of the filter in the dust holding process. The corresponding adjustment measures are put forward to provide a basis for subsequent commissioning and operation for the situation that the negative pressure and ventilation rate of the curing line room does not meet the specifications and design requirements in the dust holding process.
