Ventilation pipes are mainly used for the following purposes:
Air supply, including ventilation, such as fresh air supply and exhaust, covers a wide range, such as the air in factory workshops and production sites, which needs to be discharged outdoors and transported indoors due to the generation of harmful gases. At this time, it is necessary to use a large flow and low pressure air conveying pipeline. In general, galvanized iron pipes are used, and stainless steel pipes are used in corrosive and particularly humid places. ?
The most common way to send cold air is the pipeline of central air conditioning, which needs to be added with insulation materials. ?
Smoke exhaust, restaurants, hotels have a lot of kitchen fumes, which need to be discharged. The circular air duct used is the oil chimney. ?
Dust removal. Some factories have a lot of dust in their workshops and need special dust removal devices. ?
Bulk material transportation. In the production process of some factories, loose particles need to be transported. ?
There are the following types of ventilation ducts:
Return air duct of purification system;
Central air conditioning ventilation pipe;
Industrial air supply and exhaust ventilation pipes;
Environmental protection system suction and exhaust duct;
Mine gas drainage pipe;
Mine coated pipeline;
Fire flue ventilation pipes, etc.
