1、功能不同

1. Different functions

通风管道是工业与民用建筑的通风与空调工程用金属或复合管道，是为了使空气流通，降低有害气体浓度的一种工业及市政基础设施；

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;

排烟管道是为了避免设施在生产的时候产生的有害物质，对车间的空气造成污染，它通常都是从排风扇或吸风口将有害的物体收集，再通过管道送到净化设备处理，达到标准之后才能够排放或者是再利用。

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

通风管道一般有：净化系统送回风管、空调通风管、工业送排风通风管、系统吸排风管、矿用抽放瓦斯管、矿用涂胶布风筒等；通风管通常被应用在工业、建筑工程、城市基础建设上；

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;

排风管道的主要用途就是抽风排烟。排烟管道排烟的目的是将室内的烟尘通过抽风机械排到室外，由于烟尘经常粘在管道上，排烟管道需要经常清洗。排烟管道应用范围很广，包括酒店，工厂等等。

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、材质不同

3. Different materials

通风管道按材质分：一般有：钢板风管（普通钢板）、镀锌板（白铁）风管、不锈钢通风管、玻璃钢通风管、塑料通风管、复合材料通风管、彩钢夹心保温板通风管、双面铝箔保温通风管、单面彩钢保温风管、涂胶布通风管（如矿用风筒）、矿用塑料通风管等；

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;

按现行通风管道有关标准：排烟管道的材料选用钢板烟管(普通钢板)、镀锌板(白铁)烟管、排烟管道不锈钢排烟管道、玻璃钢排烟管道、塑料排烟管道、复合材料排烟管道、彩钢夹心保温板排烟管道、工业送排风排烟管道。排烟管道在系统分为：吸排风管、矿用抽放瓦斯管、矿用涂胶布风筒等在工业及建筑工在工厂及写字楼的空调系统，工业污染控制用除尘、排烟、吸油等排风管、工业环境或岗位舒适用送风管。

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、安装排烟管道的注意点是什么

2、 What are the precautions for installing smoke exhaust pipes

1、排烟管道的地点尤为重要，正常管道越短越好，这不仅更加美观，而且还能够将油烟排放的干净。

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、工厂酒店等每个厨房内都需配备烟道，而且烟道也是有主副分别的，主管道和整个楼体连接，而副管道是独立的，一般家中的油烟都会先储存到副管道内，再通过隔板上的孔进到主管道，因此在安装烟道时必须将副管道保存好，防止出现倒烟或串烟的情况

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
