Working principle of high-powered smoke exhaust fan

High-power smoke exhaust fans are usually used in smoke exhaust systems in industrial and commercial buildings, and their power is generally above 5KW, with high exhaust air volume and pressure, which can be used to remove large amounts of smoke, dust, pollutants and other harmful gases.

High power smoke exhaust fans are usually used in smoke exhaust systems in industrial and commercial buildings, and their application scenarios include but are not limited to the following:

Factories: There are a large number of machines and equipment inside factories and harmful gases generated during the production process, such as welding gas, paint gas, fume and dust, etc., which need to be discharged by high-power smoke exhaust fans.

Shopping malls: There are a large number of people and goods inside the shopping malls, the use of high-powered smoke exhaust fans can ensure the freshness and comfort of the air inside the mall.

Hospitals: There are various kinds of harmful gases and odors generated in the process of surgery, examination and treatment inside hospitals, which need to use high-power exhaust fans to discharge and refresh.

Restaurants: There are various ingredients and odors generated during the cooking process inside restaurants, which need to be discharged and freshened by high-powered exhaust fans.

Other industrial and commercial buildings: such as workshops, factories, large commercial centers, etc., all need to use high-power smoke exhaust fans for smoke exhaust treatment to ensure the freshness and safety of the internal air.

The working principle of smoke exhaust fan is to use the power generated by the rotation of the motor to drive the impeller to rotate, thus producing a strong airflow. In smoke exhaust systems, smoke exhaust fans are usually installed on top of buildings or in the corresponding smoke exhaust channels to ensure the quality and safety of the air inside the building by emitting smoke and harmful gases.

Smoke exhaust fan is a kind of equipment used to discharge smoke, exhaust gas and odor indoors. Its working principle is that the rotation of the fan drives the flow of air to discharge harmful gases and pollutants from indoor to outdoor.

Generally speaking, the smoke exhaust fan is mainly composed of motor, impeller, duct and control system. When the motor is started, the impeller is driven to rotate at high speed and the resulting air flow causes the air to enter the inside of the fan from the smoke vent and is forced to accelerate under the action of the impeller to form a high speed airflow. This highspeed airflow is discharged to the outside through the duct, thus enabling the discharge of indoor air.

The air volume and pressure of the smoke exhaust fan directly affects its emission efficiency, and it is usually necessary to choose a smoke exhaust fan of different specifications according to the specific needs of use. In actual use, smoke exhaust fans also need to cooperate with the corresponding control system, according to the actual needs of the switch control, speed adjustment and other operations.

In order to ensure the safety and reliability of high-powered smoke exhaust fans, a variety of factors need to be considered, such as the power and stability of the motor, the material and structure of the impeller, the design and installation of the duct, etc. In addition, it is also necessary to consider the actual needs of the use of smoke exhaust fans. In addition, it is also necessary to select and install according to the actual use requirements, such as the fan's air displacement, pressure, noise, energy consumption and other indicators.
