厨房排烟系统的构成。
Composition of kitchen smoke exhaust system.
厨房的排烟系统主要由集烟罩、排烟管道、油烟净化器、排烟风机（含*）和厨房整体补风装置构成。
The smoke exhaust system of the kitchen is mainly composed of smoke collecting hood, smoke exhaust pipe, oil fume purifier, smoke exhaust fan (including *) and integral air supplement device of the kitchen.
油烟净化器的类型和运行方式可以根据实际情况进行选择。在油烟净化器安装之前，首先要对排烟系统中各部分的实际运行参数，包括运行阻力和排风量进行核算。
The type and operation mode of fume purifier can be selected according to the actual situation. Before installing the oil fume purifier, the actual operating parameters of each part of the smoke exhaust system, including operating resistance and exhaust air volume, shall be calculated first.
如果是新建项目，在设计时要充分考虑泥杆 保定古筝 塑料增韧剂 拱形护坡模具 保定空调维修  托辊生产线安装了油烟净化器后对排风系统的影响；如果是改造项目，在加装油烟净化器时需要对排风系统重新进行核算，必要时要对集烟罩、排烟管道和厨房整体补风装置进行改造并更换排烟风机。
If it is a new project, the impact on the exhaust system after the installation of oil fume purifier shall be fully considered in the design; If it is a reconstruction project, the exhaust system needs to be recalculated when installing the oil fume purifier. If necessary, the smoke collection hood, smoke exhaust pipe and the overall air supplement device of the kitchen shall be reconstructed and the smoke exhaust fan shall be replaced.
