捕集挡板/裙边

捕集挡板或裙边是安装在排烟罩周边或特定区域的工程组件。它形成物理屏障和气流管理系统，防止工业过程中产生的有害烟雾、蒸气或颗粒物逸出。通过优化捕集速度和 containment 区域，确保污染物去除效率最大化，同时降低能耗和交叉污染风险。

挡板/裙边基于受控气流动力学和物理 containment 原理工作。它形成低压区，将污染物引向抽吸点，同时防止可能引起逸出的湍流。可调或固定设计在整个开口上保持最佳捕集速度（热羽流通常为 0.25-0.5 m/s，低动量排放为 0.5-1.0 m/s），确保污染物在扩散到工作区之前在其源头被捕获。

The baffle/skirt operates on the principle of controlled airflow dynamics and physical containment. It creates a low-pressure zone that draws contaminants toward the extraction point while preventing turbulence that could cause escape. The adjustable or fixed design maintains optimal capture velocity (typically 0.25-0.5 m/s for thermal plumes, 0.5-1.0 m/s for low-momentum emissions) across the entire opening, ensuring contaminants are captured at their source before dispersion into the workspace.
