Difference between exhaust duct and ventilation duct

In effect:

1. Ventilation ducts are a kind of municipal infrastructure to circulate air and reduce the concentration of harmful gases.

2. The exhaust pipe is to prevent the harmful substances generated by the equipment during the production process from polluting the air in the workshop. The harmful substances are often captured on-site through the exhaust hood or air suction port, and are transported to the purification equipment for treatment by pipelines. After the emission standard, it is reused or discharged into the atmosphere.

Use:

1. Ventilation ducts are used for municipal infrastructure in industrial and construction projects.

2. The exhaust duct, as the name suggests, is the exhaust.

On the material:

1. Ventilation ducts are classified by material: generally: steel duct (ordinary steel plate), galvanized sheet (white iron) duct, stainless steel ventilation duct, glass fiber reinforced plastic ventilation duct, plastic ventilation duct, composite material ventilation duct, color steel sandwich insulation board Ventilation pipe, double-sided aluminum foil insulation ventilation pipe, single-sided color steel insulation ventilation pipe, rubberized cloth ventilation pipe (such as mining air duct), mining plastic ventilation pipe, etc.;

2. Due to economic considerations, exhaust pipes are often connected into a whole by pipes to form a local exhaust system, and the whole system shares a purification equipment and a fan.

Same thing: pipes. motor. Different points go into a row one by one. The role is to see where, at home: the exhaust duct pulls out moisture, smoke, etc. Ventilation ducts keep the humidity in balance with the atmosphere. materials are similar.
