Fireproof cornice with smoke filtering function
The invention discloses a fireproof cornice with a smoke filtering function, and belongs to the technical field of building fire protection. By arranging the two fireproof hanging-down walls and the fireproof hanging-down wall, the possibility that flames bypass the two sides of the fireproof cornice can be reduced, the flames can only flow towards the front end of the fireproof cornice, the occurrence position of the flames can be changed, most of the flames are made to burn away from the building wall, and heat radiation of the flames to the wall is reduced; the surface temperature of the building wall is reduced, and the possibility of secondary combustion is reduced; by means of the flue gas filtering assembly with the variable hole diameter, the combustion process can be destroyed through heat dissipation, flame in flue gas can be filtered, eliminated and dissipated, energy distribution near a window is changed, energy which should be radiated upwards originally spreads towards the periphery more rapidly, and the purpose of limiting fire spreading is achieved.
本发明公开了一种具备烟气过滤功能的防火挑檐，属于建筑消防技术领域。本发明通过设置的两个防火下垂壁与一个防火下垂壁，可以降低火焰绕过防火挑檐两侧的可能性，使火焰只能向防火挑檐的前端流动，能够改变火焰出现位置，使绝大部分火焰远离建筑墙体燃烧，减少火焰对墙体的热辐射，降低建筑墙体的表面温度，降低二次燃烧的可能；通过设置的可变孔径的烟气过滤组件，可以通过散热破坏燃烧过程，实现对烟气中火焰的过滤、消除和耗散作用，改变了窗口附近的能量分布，使本来应该向上辐射的能量更加快速地向四周扩散，达到限制火势蔓延的目的。
