在工业通风领域处理有害气体高空排放问题时往往往采用各种半经验公式求解。[1]、[4]计算的主要内容分为排气主管高度与降落到距排气主管一定距离的地面的最大浓度两部分。本文采用文献[4]提出的排气主管高度计算法和现今国外流行的大气扩散萨顿模式来编制有害气体高空的排放电算程序.这种程序不仅能方便地求出排气主管高度和地面最大浓度,而且配上有绘图功能的计算机或计算器还可绘制出浓度随距离变化的衰减图:因而该程序具有简单、实用的特点.
In the field of industrial ventilation, when dealing with the emission of harmful gases at high altitudes, various semi-empirical formulae are often used to solve the problem. The main contents of the [1] and [4] calculations are divided into two parts: the height of the exhaust main pipe and the maximum concentration of the ground that falls to a certain distance from the exhaust pipe. In this paper, the calculation method of the exhaust main pipe height proposed in the literature [4] and the popular foreign atmospheric diffusion Sutton model are used to compile the high-altitude emission calculation program for harmful gases. This procedure can not only easily determine the height of the exhaust pipe and the ground. The computer with the largest concentration, and equipped with a graphing function, can also draw the attenuation map with the concentration changing with distance. Therefore, the program has a simple and practical feature.
