In industrial plants, the traditional ventilation and smoke extraction method is window ventilation, but this kind of ventilation and smoke extraction scheme does not meet the needs of modern enterprises, and it is necessary to install professional smoke vent skylights. Then, from the actual application analysis, what role can the automatic opening vent plays in the workshop?

1. Explanation of the ventilation and smoke exhaust principle of smoke vent skylights in steel structure workshops

The principle of smoke vents is mainly to use the wind pressure difference formed by the temperature difference between the inside and outside of the plant workshop to discharge the smoke, mist and heat generated in the production and operation process. The natural wind from the outside of the workshop blows over the roof of the workshop, and the positive wind pressure formed enters the workshop at the roof of the workshop. On the leeward side of the workshop, the air current forms a negative wind pressure, which draws the air from the side of the workshop to the wind. Under the action of pressure, the dirty air is discharged and fresh air is inhaled.

2. Ventilation and smoke exhaust performance of roof smoke vent on factory buildings

The main purpose of installing smoke vents in the factory is to ventilate and exhaust smoke, realize the unblocked air in the workshop, and create a good working environment for front-line employees, thereby improving production efficiency and product quality. In addition, the roof window of the factory building can also meet the function of firefighting linkage, which can realize the firefighting linkage through smoke, fog, rain, and temperature. Once an emergency occurs, the window sash can be quickly opened and closed.

3. The lighting performance of the smoke ventilator

The smoke ventilator is installed on the roof of the factory building. The main profile of the rainproof board is FRP daylighting board, which can not only realize rainproof and rainproof, but also meet the needs of daylighting. The roof lighting ventilator of the factory building has good light transmission performance, natural scattering and soft light, which can directly replace electric light and save electricity expenses.
