　　通風管道的主要用用哪些地方

　　What are the main uses of ventilation ducts

　　通風管道常采用鍍鋅板、不銹鋼、白鐵、冷軋鋼板、玻璃鋼防腐等高分子材料制成。它是用于輸送空氣和空氣化合物的各種管道的總稱。那么通風管道的主要用用哪些地方呢？

　　Ventilation ducts are often made of high polymer materials such as galvanized sheet, stainless steel, white iron, cold-rolled steel plate, fiberglass anti-corrosion, etc. It is a general term for various pipelines used to transport air and air compounds. So where are the main uses of ventilation ducts?

　　(1) 排風，如新風送排風管。這一類的范圍很廣，如鍍鋅焊接空氣閥廠的生產車間和制造場所的空氣。因為有害物質，須排放到室外，室外空氣須輸送到室內。此時應選用總流量大、工作壓力低的空氣輸送管道，可采用螺旋風管。一般應使用鍍鋅鐵管，在腐蝕性和非常潮濕和寒冷的場所應使用不銹鋼管。

　　(1) Ventilation, such as fresh air supply and exhaust ducts. This category has a wide range, such as the air in the production workshops and manufacturing sites of galvanized welded air valve factories. Due to harmful substances, they must be discharged outdoors and outdoor air must be transported indoors. At this time, air delivery pipelines with high total flow rate and low working pressure should be selected, and spiral air ducts can be used. Galvanized iron pipes should generally be used, and stainless steel pipes should be used in corrosive and very humid and cold environments.

　　(2)空調，國內空調管道常見，須加保溫材料。螺旋風管可粘貼保溫材料，表面美觀大方。

　　(2) Air conditioning, commonly found in central air conditioning pipelines in China, requires the addition of insulation materials. Spiral air ducts can be pasted with insulation materials, with a beautiful and generous surface.

　　(3) 排出廚房油煙。飯店、賓館和飯店的餐廳廚房均有大量的油煙，須排放。應采用圓形通風管道，即油煙煙囪。在這里，螺旋風管應該叫廚房油煙管。

　　(3) Exhaust kitchen fumes. Restaurants, hotels, and restaurant kitchens all have a large amount of oil fumes that need to be emitted. Circular ventilation ducts, such as oil fume chimneys, should be used. Here, the spiral air duct should be called a kitchen range hood.

　　(4)除灰。有的工廠裝配車間浮塵較多，須使用的除灰設備。螺旋風管可用于總風量較大的管道。

　　(4) Dust removal. Some factory assembly workshops have a lot of floating dust and require the use of professional dust removal equipment. Spiral ducts can be used for pipelines with high total air volume.

　　(5)大宗原料運輸。在一些工廠的加工過程中，須運輸松散的顆粒，特別是那些比重較小的，如泡沫顆粒。螺旋風管工程造價低，使用方便。

　　(5) Transportation of bulk raw materials. In some factories, loose particles, especially those with small specific gravity, such as foam particles, must be transported during processing. Spiral duct engineering has low cost and is convenient to use.
