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）剩余少量的油煙再進入過濾桶進行二次凈化，固態顆粒沉積在濾料上，廢油精槽道流入油盒。濾筒內濾料可方便的更換。

(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）在風機的抽吸力作用，油煙進入濾油柵進行初級凈化，大部分油煙的灰粒和液滴被截留，費油順油道流入油盒，顆粒沉積在金屬濾油柵上。濾油柵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）經過排煙罩凈化后的空氣經風機、氣管排向室外。

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

安裝現場應劃定作業區域，并設置安全標志，禁止非作業人員進入進入。進入施工現場人員應穿戴防護用品，工作服的袖口、腰部和腿部應收緊。工作時，使用管道上方和下方的安全梯子。施工期間，應在高處搭建工作平臺或腳手架，工作平臺各節點與腳手架的連接應牢固可靠。工作平臺的寬度應滿足施工安全要求，平臺內踏板的鋪設應充分、穩定。

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.

濟南排煙管道使用過程中，應隨時檢查工作平臺和腳手架。當發生變形或位移時，應采取安全措施并及時確認。一般來說，排氣扇系統和空調系統應在建筑圍護結構施工完成、障礙物清除且地面無碎片后安裝。

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.

避免管道內空氣熱損失，還可以阻止熱量散發到房間內讓室溫升高，避免人接觸風道被燙傷。在夏季因輸送氣體溫度低于周圍環境空氣露點溫度，管道外壁會結露。

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.

這對集中空調系統的風道會加大冷量損失，同時凝結水滴會污染吊頂和墻地面，因此也應該進行保冷隔熱處理，其實對于通風管道安裝施工來說，對于我們生活中的重要性我們都知道，尤其是一些人在購房時也會考慮一下通風效果怎么樣，房子在構建初期就會設計好各管道的位置，叁金來通風設備為人們擁有良好的生活品質做保障。

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.
