，车间的通风管道设计应根据车间的大小、布局以及通风需求进行规划。车间的大小和布局将决定通风管道的长度和分支数量，通风需求则决定了通风管道的直径和风量。
Firstly, the design of ventilation ducts in the workshop should be planned based on the size, layout, and ventilation needs of the workshop. The size and layout of the workshop will determine the length and number of branches of the ventilation ducts, while the ventilation demand determines the diameter and air volume of the ventilation ducts.
其次，通风管道可以选择使用金属材料如钢板、镀锌铁皮等。这些材料具有耐腐蚀、结构稳定等优点，适用于长期使用的通风系统。另外，通风管道的形状可以考虑采用矩形或圆形，根据实际情况进行选择。
Secondly, metal materials such as steel plates, galvanized iron sheets, etc. can be chosen for ventilation ducts. These materials have advantages such as corrosion resistance and structural stability, making them suitable for long-term use in ventilation systems. In addition, the shape of the ventilation duct can be considered as rectangular or circular, which can be selected according to the actual situation.
对于小型车间而言，通风管道可以分为主干管道和分支管道。主干管道负责连接车间内外的空气，将新鲜空气引入车间或排出污浊空气。分支管道则连接各个设备或工作区域，将污浊空气排出。在设，应合理安排各个分支的位置和长度，以确保通风效果。
For small workshops, ventilation ducts can be divided into main and branch ducts. The main pipeline is responsible for connecting the air inside and outside the workshop, introducing fresh air into the workshop or discharging polluted air. Branch pipelines connect various equipment or work areas to discharge dirty air. When designing, the position and length of each branch should be reasonably arranged to ensure ventilation effectiveness.
为了提高通风效果，通风管道中可以设置风门或风阀。风门可用于调节新风和排风的比例，以满足不同情况下的通风需求。风阀则可以用于分区控制，根据实际需要进行开启或关闭。
In order to improve the ventilation effect, air doors or valves can be installed in the ventilation ducts. The damper can be used to adjust the ratio of fresh air and exhaust air to meet the ventilation needs in different situations. The air valve can be used for zone control, and can be opened or closed according to actual needs.
此外，通风管道的连接方式也需要注意。通常可采用法兰连接或焊接连接方式。法兰连接适用于需要频繁拆卸和清洗的场合，而焊接连接则适用于需要长期稳定运行的场合。
In addition, the connection method of the ventilation duct also needs to be noted. Usually, flange connection or welding connection can be used. Flange connections are suitable for situations that require frequent disassembly and cleaning, while welded connections are suitable for situations that require long-term stable operation.
另外，通风管道的支撑和固定也非常重要。通风管道应该设置适当数量的支撑和固定点，以确保管道的稳定性和性。支撑和固定点可以采用金属支架或悬挂装置。
In addition, the support and fixation of ventilation ducts are also very important. Ventilation ducts should be equipped with an appropriate number of supports and fixing points to ensure the stability and safety of the ducts. Metal brackets or suspension devices can be used for support and fixing points.
然后，通风管道的安装需要考虑工艺和要求。通风系统的安装应由人员进行操作，确保管道的密封性和通风效果。同时，还需遵守相关的规范和标准，确保通风系统的运行。
Then, the installation of ventilation ducts needs to consider process and safety requirements. The installation of the ventilation system should be operated by professional personnel to ensure the sealing and ventilation effect of the pipeline. At the same time, it is also necessary to comply with relevant safety regulations and standards to ensure the safe operation of the ventilation system.
