Description

[0002] With the acceleration of urbanization and the continuous increase in building height, fire safety has become the focus of social attention. In fire accidents, smoke is often one of the important factors causing casualties and property losses. Efficient and reliable fire smoke exhaust devices are of great significance for ensuring personnel safety and reducing property losses. When a fire occurs, the smoke produced by combustion often contains a large amount of harmful smoke and particulate matter. If these smoke and particulate matter are directly discharged into the atmosphere by the smoke exhaust system, it will not only pollute the environment, but also may threaten the health of surrounding residents. The filter plate can effectively capture and filter these smoke and harmful substances, reducing their harm to the environment and human body.

The filter plates of fire smoke exhaust devices are prone to accumulate a large amount of smoke and pollutants after long-term use, resulting in a decrease in smoke exhaust efficiency. Therefore, we need to propose an intelligent fire smoke exhaust device with self-cleaning function. Utility Model Content
