1、功能不同

1. Different functions

通風管道是工業(yè)與民用建筑的通風與空調工程用金屬或復合管道，是為了使空氣流通，降低有害氣體濃度的一種工業(yè)及市政基礎設施；

Ventilation ducts are metal or composite pipes used for ventilation and air conditioning engineering in industrial and civil buildings. They are an industrial and municipal infrastructure designed to facilitate air circulation and reduce the concentration of harmful gases;

排煙管道是為了避免設施在生產的時候產生的有害物質，對車間的空氣造成污染，它通常都是從排風扇或吸風口將有害的物體收集，再通過管道送到凈化設備處理，達到標準之后才能夠排放或者是再利用。

Smoke exhaust pipes are designed to prevent harmful substances generated by facilities during production from polluting the air in the workshop. They are usually collected from exhaust fans or air intakes, and then transported through pipes to purification equipment for treatment. Only after reaching the standard can they be discharged or reused.

2、用途不同

2. Different uses

通風管道一般有：凈化系統(tǒng)送回風管、中央空調通風管、工業(yè)送排風通風管、環(huán)保系統(tǒng)吸排風管、礦用抽放瓦斯管、礦用涂膠布風筒等；通風管通常被應用在工業(yè)、建筑工程、城市基礎建設上；

Ventilation ducts generally include: return air ducts for purification systems, central air conditioning ventilation ducts, industrial supply and exhaust ventilation ducts, environmental protection system suction and exhaust ducts, mining gas drainage ducts, mining coated fabric air ducts, etc; Ventilation pipes are usually used in industries, construction projects, and urban infrastructure construction;

排風管道的主要用途就是抽風排煙。排煙管道排煙的目的是將室內的煙塵通過抽風機械排到室外，由于煙塵經常粘在管道上，排煙管道需要經常清洗。排煙管道應用范圍很廣，包括酒店，工廠等等。

The main purpose of exhaust ducts is to extract air and smoke. The purpose of smoke exhaust pipes is to exhaust indoor smoke and dust to the outside through ventilation machinery. As smoke and dust often stick to the pipes, the smoke exhaust pipes need to be cleaned regularly. The application range of smoke exhaust pipes is very wide, including hotels, factories, and so on.

3、材質不同

3. Different materials

通風管道按材質分：一般有：鋼板風管（普通鋼板）、鍍鋅板（白鐵）風管、不銹鋼通風管、玻璃鋼通風管、塑料通風管、復合材料通風管、彩鋼夾心保溫板通風管、雙面鋁箔保溫通風管、單面彩鋼保溫風管、涂膠布通風管（如礦用風筒）、礦用塑料通風管等；

Ventilation ducts are generally divided by material: steel plate ducts (ordinary steel plates), galvanized sheet (white iron) ducts, stainless steel ducts, fiberglass ducts, plastic ducts, composite material ducts, color steel sandwich insulation board ducts, double-sided aluminum foil insulation ducts, single-sided color steel insulation ducts, coated fabric ducts (such as mining ducts), mining plastic ducts, etc;

按國家現行通風管道有關標準：排煙管道的材料選用鋼板煙管(普通鋼板)、鍍鋅板(白鐵)煙管、排煙管道不銹鋼排煙管道、玻璃鋼排煙管道、塑料排煙管道、復合材料排煙管道、彩鋼夾心保溫板排煙管道、工業(yè)送排風排煙管道。排煙管道在環(huán)保系統(tǒng)分為：吸排風管、礦用抽放瓦斯管、礦用涂膠布風筒等在工業(yè)及建筑工在工廠及寫字樓的中央空調系統(tǒng)，工業(yè)污染控制用除塵、排煙、吸油等排風管、工業(yè)環(huán)境或崗位舒適用送風管。

According to the current national standards for ventilation ducts, the materials used for smoke exhaust ducts are steel plate smoke ducts (ordinary steel plates), galvanized sheet (white iron) smoke ducts, stainless steel smoke ducts, fiberglass smoke ducts, plastic smoke ducts, composite material smoke ducts, color steel sandwich temperature insulation plate smoke ducts, and industrial air supply and exhaust smoke ducts. Smoke exhaust ducts in environmental protection systems are divided into: suction and exhaust ducts, mining gas drainage ducts, mining adhesive coated air ducts, etc. in central air conditioning systems for industrial and construction workers in factories and office buildings, dust removal, smoke exhaust, oil suction and other exhaust ducts for industrial pollution control, and air supply ducts for comfortable industrial environments or positions.

二、安裝排煙管道的注意點是什么

2、 What are the precautions for installing smoke exhaust pipes

1、排煙管道的地點尤為重要，正常管道越短越好，這不僅更加美觀，而且還能夠將油煙排放的干凈。

1. The location of the smoke exhaust duct is particularly important. The shorter the normal duct, the better. This not only makes it more aesthetically pleasing, but also allows for a clean discharge of oil fumes.

2、工廠酒店等每個廚房內都需配備煙道，而且煙道也是有主副分別的，主管道和整個樓體連接，而副管道是獨立的，一般家中的油煙都會先儲存到副管道內，再通過隔板上的孔進到主管道，因此在安裝煙道時必須將副管道保存好，防止出現倒煙或串煙的情況

2. Every kitchen, such as factories, hotels, etc., needs to be equipped with a flue, and the flue is also separate from the main and auxiliary pipelines. The main pipeline is connected to the entire building, and the auxiliary pipeline is independent. Generally, the oil fume in the home is stored in the auxiliary pipeline first, and then enters the main pipeline through the holes on the partition. Therefore, when installing the flue, the auxiliary pipeline must be well preserved to prevent the occurrence of backflow or string smoke
