Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire protection engineering equipment technology, and in particular to a smoke exhaust device for fire protection engineering. Background Technology
[0002] Fire protection engineering smoke extraction devices are specialized equipment used to quickly remove smoke in fire and other fire emergencies. Their core function is to actively extract smoke generated by the emergency by working in conjunction with the adjustable-angle support base plate and the smoke extraction components. The smoke is then introduced into the treatment box through a connecting pipe for multi-stage filtration and purification. The activated carbon filter plate adsorbs harmful particles and odor molecules, and the clean gas is then accelerated out through the air guide duct with spiral guide grooves and guide vanes. At the same time, a collection box collects large particles of dirt, ultimately achieving the comprehensive goals of efficient smoke extraction, environmental purification, and reduction of smoke hazards.
[0003] Existing fire protection engineering smoke exhaust systems have significant defects in smoke treatment and emission. They mostly use a single filter layer or a simple adsorption structure, which has limited effectiveness in intercepting harmful particles, odor molecules and large particulate pollutants mixed in the smoke, resulting in the possibility of residual pollutants in the purified gas. At the same time, the design of smoke exhaust channels lacks airflow optimization mechanisms, which can easily reduce emission efficiency due to airflow turbulence, and even form deposits in the pipes, exacerbating the equipment load and increasing the complexity and time cost of equipment maintenance.
[0004] Existing smoke extraction systems in fire protection engineering suffer from significant deficiencies in smoke treatment and emission. Most systems employ a single filter layer or simple adsorption structure, offering limited effectiveness in intercepting harmful particles, odor molecules, and large particulate matter mixed in the smoke, resulting in residual pollutants in the purified gas. Furthermore, the lack of airflow optimization mechanisms in smoke extraction duct designs easily leads to reduced emission efficiency due to airflow turbulence, and even sediment buildup within the ducts, increasing equipment load and complicating maintenance. This solution significantly improves the thoroughness of smoke purification through multi-layer filtration and spiral flow guidance technology, ensuring that emitted gases meet environmental standards. Secondly, the combination of guide vanes and spiral ducts optimizes the airflow path, reduces energy loss, and makes the smoke extraction process more efficient, effectively enhancing the purification effect and smoke extraction efficiency of fire protection engineering.
