摘要
大气污染日益严重,粉尘是一个主要的污染源。在治理粉尘污染方面,袋式除尘器的地位越来越重要。除尘的核心部件布袋对于粉尘的温度有严格的要求,面对电熔镁产生的高温粉尘,降温成为首要任务。在参数复杂多变的高温粉尘流场中,利用风扇的扰动来增强散热和稳定流速有很好的效果,结合流体力学的计算分析结果,根据风扇流量确定叶片安装角、叶型半径、叶片数和转速,运用传热学从数学分析的角度判断风扇扰动对散热量的影响。实践证明,风扇扰动能够增强流体热量散失。
Air pollution is becoming more and more serious, in which dust is a major source of pollution. Bag filter plays an important role in dust control. Bags which are core parts in bag filter have strict requirements on temperature, so cooling is the most important task in face of the high temperature dust produced by fused magnesia. The disturbanced air by fan to enhance heat dissipation and stable flow rate has an obvious effect in high temperature dust flow field which parameters are complicated and changeable. Blade installation angle, blade profile radius, blade number and rotation rate are determined by fan flow quantity which is derived from the computational results of fluid mechanics. The influence of fan disturbance on heat dissipation is analyzed based on heat transfer theory. The result is that fan disturbance can be used to enhance the fluid heat dissipation.
