The results of modeling the processes of capturing harmful emissions from galvanic baths or other tanks with an open surface are presented. An approach based on a numerical determination of the concentration of contaminated substances in the working areas of the room is proposed to evaluate the effectiveness of airborne suction. The fields of air velocity and concentration of harmful vapors in the working area are calculated. The dependence of the flow velocity around the surface of the technological solution on the distance between the surface of the solution and the lower edge of the suction is determined. It is shown that increasing the efficiency of airborne suction can be achieved by mechanical shielding — installation of impervious thin visors on the sides of the bath. The height of the mechanical screen should be about 0.5 of the width of the tank.

露天水库在船上吸气附近对流蒸气流的建模

给出了模拟过程的结果，该过程捕获了从电镀浴池或其他具有敞开表面的水箱中排放的有害物质。提出了一种基于数值确定房间工作区域中污染物质浓度的方法，以评估空中抽吸的有效性。计算工作区域中的风速和有害蒸气浓度的字段。确定围绕工艺溶液表面的流速对溶液表面与吸力下边缘之间距离的依赖性。结果表明，通过机械屏蔽（在浴池侧面安装不透水的薄遮阳板）可以提高机载抽吸效率。机械屏幕的高度应约为0。
