Roof natural ventilator is installed on the roof of the factory, which can quickly discharge the smoke and exhaust gas generated during production and operation activities, keep the air in the workshops smooth, and provide a good production environment for frontline employees and meet ventilation and smoke exhaust requirements of modern industrial plants.

1. Analysis of the ventilation principle of natural ventialtor

The roof vents use the thermal pressure formed by the temperature difference between indoor and outdoor and the wind pressure caused by the action of wind to realize natural ventilation of industrial plant ventilation equipment. Roof smoke vent mainly relies on the effect of temperature difference between indoor and outdoor. After the temperature difference reaches a certain level, it will automatically discharge smoke and exhaust gas and inhale fresh air to achieve the purpose of circulating the air in the workshop.

2. The structure of the smoke exhaust ventilator of the factory building

Factory smoke vent is customized products. Different industries, project sites and business owners, even the same type of ventilation skylights are designed differently. But from the analysis of the structure of smoke ventilation, it is mainly composed of the main frame, the secondary frame, the deflector, the rain plate, and the electric control box.

3. Throat size of continuous rooflight in metallurgical workshop

The metallurgical plant belongs to the heavy industry industry. A large amount of smoke will be generated during the production process. Generally, large throat streamlined natural ventilator is used. The ventilation skylight of the metallurgical plant can be divided into 1500-9000mm according to the size, and it can also be designed according to the specific situation of the project. In order to meet the demand of ventilation and smoke exhaust of the plant.
