The wind cabinet manufacturer tells you that the spiral air duct is the pipe used for air transportation. Classification according to raw materials and section shape. According to the raw materials, the air ducts can be divided into Sauss air ducts, metal air ducts, composite air ducts, etc; According to the section shape, it can be divided into round air duct, rectangular air duct, flat round air duct, etc. At present, rectangular air duct is mainly used.
1、 Main purpose of spiral air duct:
1. Deliver cold air. The most common is the pipeline of central air conditioner, in which the composite air duct contains phenolic insulation materials, without additional external insulation. The construction period is short, the production device is simple, and the exposed installation is beautiful and generous.
2. Air supply and ventilation, such as the air in factory workshops and production sites, are required to discharge harmful gases outdoors. In general, composite air duct can be used. Aluminum foil phenolic, color steel phenolic composite air duct or galvanized iron sheet composite air duct can be selected according to the air pressure and the nature of the site.
3. Transportation of bulk materials. In some production processes, loose particles need to be transported, especially those with small proportion, such as foamed plastic particles. The use of air ducts is cheap and effective.
4. Dedusting. In some places, there is a lot of dust, and special dust removal device is required. For pipes with large air flow, spiral air pipes can be used.
5. Exhaust lampblack. A large amount of lampblack is produced in restaurants, restaurants and kitchens. The use of circular air ducts is called lampblack chimneys. It should be called lampblack here.
