The invention discloses a smoke blocking type fireproof door. The smoke blocking type fireproof door comprises a door plate and a door frame, a concave part is arranged on the edge of the door plate,a blocking block used for carrying out sealing on a gap between the door plate and the door frame is arranged on the edge of the door plate, meanwhile, a filter screen used for carrying out filteringon smoke generated in a fire disaster is arranged in the door frame, a low-pressure water tank is further arranged in the door plate, an air bag is arranged on the surface of the blocking block, the low-pressure water tank communicates with the air bag, and water vapor formed by the low-pressure water tank can form an outer vapor flowing ring and an inner vapor flowing ring in the concave part ofthe door plate, so that certain blocking effect on the smoke is achieved. According to the smoke blocking type fireproof door, smoke sealing and flow blocking can be carried out on the gap between thedoor plate and the door frame, and therefore the smoke blocking effect of the fireproof door is improved, and a positive effect on breathing safety of personnel in a fire scene is achieved.
本发明公开了一种烟气阻断式防火门，包括门板和门框，所述门板的边缘设置凹陷部，在门板边缘设置用于对门板和门框之间的缝隙进行密封的堵块，同时在门框中设置用于对火灾中产生的烟气进行过滤的过滤网，门板内部还设置低压水箱，堵块表面设置气囊，低压水箱与气囊连通，低压水箱形成的水蒸气可在门板的凹陷部形成外、内两个蒸汽流动圈，对烟气起一定阻隔作用，本发明中的烟气阻断式防火门可对门板和门框之间缝隙处进行烟气的密封和阻流，提升防火门的烟气阻隔效果，对火灾现场的人员的呼吸安全具有积极作用。
