Ventilation duct is indispensable in multi-storey buildings. After a period of application, it is necessary to carry out cleaning and maintenance work. What are the actual ways?

1、工業設備法：此方法非常容易實際操作、難度系數小、勞動量小、花費低的通風管道清洗方法，但清洗功效另外也是太差的。清洗周期時間為大半年下列的豎通風管道清洗，這類清洗方法毫無疑問是非常好的選擇。

1. Industrial equipment method: this method is very easy to operate, the difficulty coefficient is small, the amount of labor is small, the cost is low, but the cleaning effect is also too poor. This kind of cleaning method is undoubtedly a very good choice for the vertical ventilation pipe cleaning whose cleaning cycle time is less than half a year.

操作步驟：向通風管道內噴撒化除油劑后，用能夠伸進通風管道內長達30米的電動式軟軸刷和氣動式軟軸刷對濟南市通風管道內腔開展清洗。通風管道清洗方案是：技能員工根據通風管道清洗具體情況，計算出每過必然間距拆卸一節通風管道并向2個方位拓寬清洗，以保證清洗徹 底，保證清洗的品質。

Operation steps: after spraying deoiling agent into the ventilation pipe, clean the inner cavity of Jinan ventilation pipe with electric flexible shaft brush and pneumatic flexible shaft brush which can reach 30 meters into the ventilation pipe. The cleaning scheme of ventilation pipe is: according to the specific situation of ventilation pipe cleaning, the skilled staff can calculate the necessary distance to dismantle a section of ventilation pipe and broaden the cleaning to two directions, so as to ensure the thorough cleaning and the quality of cleaning.

2、拆卸法：此方法是徹 底、清洗功效不錯的清洗方法，但工程施工難度系數大，職工量也大，另外花費也相對性較高。

2. Disassembly method: this method is a thorough cleaning method with good cleaning effect, but the difficulty coefficient of engineering construction is large, the number of workers is large, and the cost is relatively high.

1、送冷氣機：廣泛的是家庭裝家用中 央空調的管道，螺旋式風管可內貼隔熱保溫原材料，表層看來別具一格。

1. Supply air conditioner: it is widely used for household central air conditioning. The spiral air duct can be pasted with heat insulation raw materials, and the surface layer seems unique.

2、排油煙。餐飲店、酒店餐廳、酒店餐廳的廚房餐廳均有很多油煙導致，務必排出去，運用環狀的通風風管就是油煙囪。在這兒，螺旋式風管也可稱之為油煙管。

2. Exhaust oil fumes. There are a lot of oil fumes in restaurants, hotel restaurants, kitchens and restaurants of hotel restaurants. It is necessary to exhaust them. The annular ventilation duct is the oil chimney. Here, the spiral duct is also called the lampblack duct.

3、除塵。一些制造廠生產流水線很多塵土，除塵裝置，在這其中風 流量非常大的管道，可運用螺旋式風管。

3. Dust removal. There are a lot of dust and dust removal devices in the production line of some manufacturers. Spiral air pipes can be used for the pipes with large air flow.

通風管道的功效。

The effectiveness of ventilation ducts.

1.減少實際操作負壓力。在冬天，假如雞棚內沒有安裝通風管道，應應用小窗子自然通風，特別是在跨距很大的雞棚內，應選用高負壓力自然通風，便于有用、安 全性地引風機。通風管道的應用，是由于管道中的送風大部分不是外擴散的，低負壓力是依照管道的方位，風從接口處先后根據。

1. Reduce the negative pressure of actual operation. In winter, if there is no ventilation pipe installed in the chicken shed, small windows should be used for natural ventilation, especially in the chicken shed with large span, high negative pressure natural ventilation should be selected to facilitate the use and safety of induced draft fan. The application of ventilation duct is due to the fact that most of the air supply in the duct is not externally diffused, and the low negative pressure is in accordance with the direction of the duct, and the wind is successively distributed from the interface.

2、部位高，風速勻稱。盡管進到的氣體在管道中沒有被加熱，可是降低部位高，往下外擴散的時間就是加熱全過程。

2. The position is high and the wind speed is even. Although the incoming gas is not heated in the pipeline, the whole process of heating is the time when the lower part is high and the gas diffuses downward and outward.

3.散熱風扇配備有用。在打開散熱風扇的原始環節，因為設計方案難題，進氣窗應用不安 全。

3. The cooling fan is equipped with a cooling fan. In the original part of opening the cooling fan, because of the design problem, the application of the air inlet window is not safe.
