集气罩的规划关于排烟体系具有重要的影响。集气罩规划不合理就很简单形成整个排烟体系不畅。引起排烟体系不晓畅的要素有：1）油板间或许运水集气（烟）罩缝隙过小，这种状况较多；2）烟罩内搜集油烟的开口总的截面积太小而引起全体排烟不晓畅；3）开口分布不合理或是开口没有跟着与主管道的距离增大而增大，然后引起部分排烟不晓畅；4）集气（烟）罩上面的集烟管道截面积太小，导致出烟不晓畅。
The layout of the hood has important influence on the exhaust system. The layout of the hood is unreasonable, and the whole exhaust system is not smooth. The main factors causing the smoke exhaust system to be unobstructed are: 1) the gap between the oil panels may be too small, which is more common; 2) the total cross-sectional area of the oil fume collection opening in the hood is too small to cause the smoke exhaust to be unobstructed; 3) the distribution of the opening is unreasonable or the opening does not increase with the distance from the main pipe. Then cause part of the smoke exhaust is not clear; 4) collector (smoke) cover above the cross-sectional area of the smoke collection pipe is too small, resulting in smoke not clear.
济南厨房排烟罩主要由集烟罩、排烟管道、油烟净化器、排烟风机（含*）和厨房全体补风设备构成，办法如下:
Jinan kitchen smoke hood is mainly composed of smoke hood, smoke exhaust pipe, lampblack purifier, smoke exhaust fan (including *) and all kitchen air supply equipment, the methods are as follows:
1、固定烟机挂板：在装置方位钻好孔用十字螺丝将包装箱顺便的烟机挂板固定在墙上；
1. Fixing the hanging board of the cigarette machine: drilling holes in the orientation of the device and fixing the hanging board of the cigarette machine incidentally to the wall with the cross screw;
2、将烟机挂在挂板上：将吸油烟机挂到挂板上，确保吸油烟机无晃动和脱钩现象并尽量确保水平；
2. Hang the smoke machine on the hanging board: hang the lampblack machine on the hanging board to ensure that the lampblack machine does not shake and decouple and to ensure the level as far as possible;
3、装置排烟管：将排烟管的一端与吸油烟机上的出风口衔接，另一端则与共用烟道或外墙上的墙孔衔接。若排烟到共用烟道，勿将排烟管刺进过深导致排烟阻力增大，若排烟到墙外，则主张在排烟管外装上百叶窗，一起务必使排烟管口伸出30mm，防止回灌；
3. Device exhaust pipe: connect one end of the exhaust pipe with the air outlet on the lampblack suction machine, and the other end with the common flue or wall hole on the outer wall. If the smoke is exhausted to the common flue, do not puncture the smoke pipe too deep to increase the smoke exhaust resistance. If the smoke is exhausted to the wall, it is advocated to install shutters outside the smoke exhaust pipe, together with the smoke exhaust pipe must be extended 30 mm to prevent re-filling.
4、装置油杯：将油杯拧上或是推入到位固定好。
4. Install the oil cup: screw the oil cup or push it in place.
因为厨房所在建筑物的格局以及厨房在建筑物中方位不同，有条件的厨房应由建筑物的会集空调体系进行有序送风。但目前所遇到的大部分状况是建筑物没有设置厨房的送风体系。济南厨房排烟罩许多带餐厅、厨房等的建筑物，仅规划了会集采暖体系而无会集空调体系。当厨房处于作业状况时，排风体系投入运行，厨房内处于负压状况，新风来历包含室外新风浸透和餐厅的空气很多补入厨房。

But most of the current situation is that the building has no kitchen air supply system. Jinan kitchen smoke hood with many restaurants, kitchens and other buildings, only the planning of the assembly heating system without the assembly air conditioning system. When the kitchen is in operation, the exhaust system is put into operation, the kitchen is in a negative pressure condition, fresh air has always included outdoor fresh air soaking and dining room air into the kitchen.
用两台机组分别为餐厅、厨房服务，其间厨房为全新风直流体系，直接弥补厨房炉灶的排风，而餐厅为一次回风全新空气体系，这个计划能确保餐厅和厨房的空调作用，并且厨房和餐厅体系互不搅扰，缺点是初出资较大。
The kitchen serves the dining room and the kitchen respectively. The kitchen is a fresh air direct current system, which directly compensates for the exhaust of the kitchen stove. The dining room is a fresh air system with one return. This plan can ensure the air conditioning function of the dining room and the kitchen, and the kitchen and the dining room system are not disturbed each other.
