摘要: 针对高层住宅集中排烟系统中普遍存在的排烟不畅、串味等问题,提出了一种带导流板和变压板的新型变压止逆阀,并通过流场仿真计算,分析其对公共烟道排烟性能的影响。结果表明:在70%吸油烟机开启率下,导流板提高了公共烟道主管和支管静压,最大分别提升约28 Pa和46 Pa,同时降低了支管排烟量,最多降低约110 m3/h,从而提升了烟道防倒灌能力,防倒灌效果受导流板水平角度的影响,当角度为30°时效果最好;变压板能进一步提升静压,降低排烟量,但会削弱烟道防倒灌能力。

Abstract: In centralized exhaust systems of high-rise residential buildings, common issues such as poor smoke discharge and cross-contamination of odors are prevalent. To address these problems, a novel variable-pressure relief valve is introduced, which is equipped with a flow guide plate and a variable pressure plate. Through computational fluid dynamics simulations, the impact of this valve on the exhaust performance of the common exhaust duct is analyzed. The results demonstrate that at a 70% exhaust fan operation rate, the flow guide plate increases the static pressure in both the main and branch pipes of the common flue by a maximum of approximately 28 Pa and 46 Pa, respectively, while reducing the smoke extraction volume of the branch pipe by a maximum of about 110 m³/h, thereby improving the backflow prevention capability of the flue; the backflow prevention effect is affected by the horizontal angle of the guide plate, with the best effect achieved at an angle of 30°; the pressure-transforming plate can further increase the static pressure and reduce the smoke extraction volume, but it weakens the backflow prevention capability of the flue.
