厨房排烟工程的安装是一个很细致的工作，有的时候处理不好，就可能有噪音发出，所以在进行厨房排烟工程安装的时候一定要做好静音处理，那厨房排烟工程的静音工作应该怎么做好呢，
The installation of kitchen smoke exhaust engineering is a very detailed work. Sometimes, if it is not handled properly, there may be noise. Therefore, when installing the kitchen smoke exhaust project, we must do a good job of mute treatment. How should we do a good job in the silent work of kitchen smoke exhaust engineering,
通风工程对于工厂、仓库、饭店等都是需要准备的设备，通风工程主要负责通风、引风、排风、除尘等工作，济南酒店厨房排烟罩平常看到的风扇、空调其实都是通风工程的一种。那么像一般在工厂、烧烤店等安装的通风装置是利用风管，因此在通风工程的施工之前要做好准备工作，一起来了解一下吧。
