With the improvement of living standards, people also have a new understanding of kitchen smoke exhaust pipes. However, after some smoke exhaust pipes are installed, some are blocked and the design is unreasonable: the expected saturation value of diners during decoration is lower than the current dining saturation value, the workload of kitchen increases, multiple stoves operate at the same time, the original design fan speed is low and the smoke exhaust volume is small, resulting in poor smoke exhaust. A fan type four leaf or six leaf smoke exhaust fan is installed at the smoke exhaust outlet to improve the smoke exhaust volume; Or replace the high wind fan.

（1）剩余少量的油烟再进入过滤桶进行二次净化，固态颗粒沉积在滤料上，废油精槽道流入油盒。滤筒内滤料可方便的更换。

(1) The remaining small amount of oil fume enters the filter barrel for secondary purification, the solid particles are deposited on the filter material, and the waste oil fine channel flows into the oil box. The filter material in the filter cartridge can be easily replaced.

（2）在风机的抽吸力作用，油烟进入滤油栅进行初级净化，大部分油烟的灰粒和液滴被截留，费油顺油道流入油盒，颗粒沉积在金属滤油栅上。滤油栅可以方便的取下清洗。

(2) Under the suction force of the fan, the oil fume enters the oil filter grid for primary purification, most of the ash particles and droplets of the oil fume are intercepted, the waste oil flows into the oil box along the oil passage, and the particles are deposited on the metal oil filter grid. The oil filter grid can be easily removed for cleaning.

（3）经过排烟罩净化后的空气经风机、气管排向室外。

(3) The air purified by the smoke exhaust hood is discharged outdoors through the fan and air pipe.

安装现场应划定作业区域，并设置安全标志，禁止非作业人员进入进入。进入施工现场人员应穿戴防护用品，工作服的袖口、腰部和腿部应收紧。工作时，使用管道上方和下方的安全梯子。施工期间，应在高处搭建工作平台或脚手架，工作平台各节点与脚手架的连接应牢固可靠。工作平台的宽度应满足施工安全要求，平台内踏板的铺设应充分、稳定。

The installation site shall delimit the operation area and set up safety signs to prohibit non operators from entering. Personnel entering the construction site shall wear protective articles, and the cuffs, waist and legs of work clothes shall be tightened. When working, use safety ladders above and below the pipe. During construction, a working platform or scaffold shall be built at a high place, and the connection between each node of the working platform and the scaffold shall be firm and reliable. The width of the working platform shall meet the construction safety requirements, and the laying of pedals in the platform shall be sufficient and stable.

济南排烟管道使用过程中，应随时检查工作平台和脚手架。当发生变形或位移时，应采取安全措施并及时确认。一般来说，排气扇系统和空调系统应在建筑围护结构施工完成、障碍物清除且地面无碎片后安装。

During the use of Jinan smoke exhaust pipe, the working platform and scaffold shall be inspected at any time. In case of deformation or displacement, safety measures shall be taken and confirmed in time. Generally speaking, the exhaust fan system and air conditioning system shall be installed after the construction of building envelope is completed, obstacles are removed and the ground is free of debris.

避免管道内空气热损失，还可以阻止热量散发到房间内让室温升高，避免人接触风道被烫伤。在夏季因输送气体温度低于周围环境空气露点温度，管道外壁会结露。

It can avoid the heat loss of the air in the pipe, prevent the heat from being dissipated into the room, raise the room temperature, and prevent people from being scalded when contacting the air duct. In summer, because the temperature of the transported gas is lower than the dew point temperature of the surrounding air, the outer wall of the pipeline will condense.

这对集中空调系统的风道会加大冷量损失，同时凝结水滴会污染吊顶和墙地面，因此也应该进行保冷隔热处理，其实对于通风管道安装施工来说，对于我们生活中的重要性我们都知道，尤其是一些人在购房时也会考虑一下通风效果怎么样，房子在构建初期就会设计好各管道的位置，叁金来通风设备为人们拥有良好的生活品质做保障。

This will increase the loss of cooling capacity for the air duct of the central air conditioning system. At the same time, condensate droplets will pollute the ceiling and wall ground. Therefore, cold insulation treatment should also be carried out. In fact, for the installation and construction of ventilation duct, we all know the importance to our life, especially some people will consider the ventilation effect when buying a house, In the early stage of construction, the location of each pipeline will be designed, and sanjinlai ventilation equipment will ensure people's good quality of life.
