酒店厨房排烟罩的设计及计算方式介绍
1、厨房排烟罩安装的墙体，它的构造和材料都应该要有足够的强度。排烟管、风管的外墙开口，可采用砌筑预制带洞混凝土块或预埋钢管留洞方式。保温墙(更好要用空心砖)与正常墙壁的安装方法一样，如果墙面不够结实的话，那么就要用木板或其他材料进行加固。
1. The structure and materials of the wall installed with the kitchen smoke exhaust hood should have sufficient strength. The external wall openings of smoke exhaust pipes and air ducts can be made of prefabricated concrete blocks with holes or embedded steel pipes. The installation method of thermal insulation wall (hollow brick is preferred) is the same as that of the normal wall. If the wall is not solid enough, wood or other materials should be used for reinforcement.
2、厨房排烟罩安装的烟管直接穿过外墙室外，应该在室外排气口设置防止污染环境和避风的构件。共用竖向烟道连接的吸油烟机，它的竖向烟道的断面应根据所负担的排气量计算确定。
2. The smoke pipe installed on the kitchen smoke exhaust hood directly goes through the exterior wall to the outside, and the outdoor exhaust outlet should be equipped with components to prevent environmental pollution and avoid wind. For a range hood connected by a common vertical flue, the section of its vertical flue shall be calculated and determined according to the borne exhaust volume.
3、厨房排烟罩安装顶吸式的安装高度应该在燃气炉灶上方少65 厘米的地方，在65-75 厘米之间是比较合适的。
3. The installation height of the top suction exhaust hood in the kitchen should be at least 65cm above the gas stove, which is more appropriate between 65-75cm.
