摘要:
槽边射流吹吸罩已广泛应用，但以射流理论为基础的计算方法多通过经验确定关键控制参数，并进行设计和应用，忽略了一些因素对吹吸流场的影响，难以准确确定槽边射流吹吸罩控制面板位置和控制污染物所需最小风速的要求。因此，以苏联巴杜林的射流末端速度法为例，利用计算机流体力学计算技术，对不同送排风速情况下三维槽边射流吹吸罩的流场分布和毒物控制效果进行模拟分析，确定槽边射流吹吸罩控制面位于0.6～0.8 L的位置，一般取0.65 L的位置，为防止污染物扩散，控制面的风速不宜小于1.28 m/s。
Abstract:
The jet push-pull hood for industrial tank has been widely used, but the key control parameters are usually determined by experience for the computing methods based on the jet theory, and put into design and application. The influence of some factors on the push-pull flow field is neglected, so it is difficult to accurately determine the position of the capture face and the minimum wind speed needed to control the pollutant for the push-pull hood. Therefore, taking the jet end speed method of B.B.Batyphh as an example, the flow field distribution and poison control effect of a three-dimensional jet push-pull hood for industrial tank under different air supply and exhaust speeds were simulated and analyzed by using the computer fluid dynamics (CFD) technology. It was determined that the control face of jet push-pull hood is located at the position of 0.6-0.8 L, generally taking the position of 0.65 L. In order to prevent the diffusion of pollutants, the capture velocity should not be less than 1.28 m/s.
