核化工厂大型排风道三通连接构件优化研究

Study on the Optimization of the T Connection Component of the Large Exhaust Duct in a Nuclear Chemical Plant

核化工厂区排风道距离长,阻力大,消耗了相当一部分风机压头,为减少厂区风道阻力,需要重点研究支风道与主风道连接处的局部阻力。本文针对核化工厂区大型排风道的一种常用"T"形三通连接形式,运用三维模拟技术,从节能减阻、预防回流与减少污染物沉积的角度对其进行了优化计算分析,确定了优化措施,达到了减少阻力和避免污染积累的目的,为良好工程实践提供了理论支撑。

In this paper,three-dimensional simulation technique is used to optimize the T joint of the large exhaust duet in a nuclear chemical plant from the aspects of saving energy,reducing resistance,preventing backflow and reducing pollutant deposition.Some optimizations are analyzed and tested,which provides theoretical support for better engineering practice.
