The smelting industry is a heavy industry, which generates a lot of smoke, dust, mist, acid mist, water vapor and heat. If the smoke can not be removed to outdoor in time, it is easy to pollute the air in the workshop, endanger the health of employees, and reduce production efficiency. From a long-term development perspective, it is not conducive to the development of enterprises. Therefore, roof vents are installed on the roof of the smelting plant. The main application of steel structure smoke vents will be analyzed below.

1. Working principle of roof vents

The smoke ventilator mainly uses the thermal effect of air to exhaust the polluted air out of the workshop through thermal action, and then inhale the fresh air from the outside of the workshop inside to keep the air in the production workshop unblocked. The steel structure roof ventilators are installed in the workshop to control the harmful substances produced during the production process, including dust, smoke, steam, harmful gases, and residual heat and heat.

2. Application and design of smoke ventilation

As an important ventilation and smoke extraction equipment for industrial plants, roof smoke vent needs to be subdivided in the application field. For industries with large ventilation and smoke exhaust, large throat ventilators need to be designed to meet the greater demand for ventilation and smoke extraction; For industries with small ventilation and smoke exhaust, the throat size needs to be designed according to the actual situation of the project site. The plant ventilators are customized products and need to be designed in accordance with the specific industry, project location and Party A’s requirements.

3. The electric control equipment of the smoke vent rooflight

The main control method of the smoke vent rooflight of the factory is electric control, one-button opening and closing, convenient operation, and can realize the fire-fighting linkage function. According to the temperature, smoke, fog, and rain, it can realize the fire-fighting linkage to ensure that the ventilation skylight is in place. Under various extreme conditions, it can be quickly turned on.
