高層住宅廚房集中排煙系統(tǒng)的模擬與優(yōu)化研究
發(fā)布時間：2018-07-23 07:52
【摘要】：近年，高層建筑已是城市住宅的普遍形式，而廚房是住宅的重要組成部分，且室內(nèi)空氣品質(zhì)也越來越受到人們的關(guān)注。目前高層住宅廚房煙道主要采用的是共用豎井的集中排煙系統(tǒng)，這種排煙方式存在底部油煙無法完全排出，樓層之間串煙、倒灌等問題；在整個排煙道系統(tǒng)中，排煙不均勻；這些現(xiàn)象使得油煙等有害氣體大量存在于廚房中，對人體健康造成很大的危害。 本文是在國內(nèi)外有關(guān)研究的基礎(chǔ)上，對高層住宅廚房集中排煙氣系統(tǒng)中存在的問題進行了進一步的探討、分析與研究。主要是通過實驗測試和利用計算機進行數(shù)值模擬的方法，分析研究高層住宅廚房排煙道系統(tǒng)，探求解決煙氣無法完全排出、串煙、倒灌等問題的方法。 本文通過對33層兩種不同截面排煙道系統(tǒng)的實驗測試，并對實測數(shù)據(jù)進行分析、對比總結(jié)和分析了煙道內(nèi)煙氣的流動特性，以及煙道排煙效果差等的原因。在實驗研究的基礎(chǔ)上，對不同高度樓層（33、24、18、12、9、6層）的排煙道進行不同截面尺寸的數(shù)值模擬，最終確定了不同高度樓層排煙道的適合的截面尺寸。 在上述研究基礎(chǔ)上，結(jié)合兩次實驗的排煙道系統(tǒng)模型，分別對兩次實驗?zāi)Ｐ瓦M行了數(shù)值模擬，分析排煙量不足、排煙氣不均勻等問題的原因。并利用數(shù)值模擬對兩次實驗?zāi)Ｐ瓦M行了不同形式的優(yōu)化，即煙道內(nèi)部靜壓的豎向分區(qū)、改變煙道內(nèi)部導(dǎo)流構(gòu)件的形式等，優(yōu)化方案對存在的問題有了一定程度的改善。 結(jié)合33層排煙道系統(tǒng)的分析方法，及優(yōu)化的導(dǎo)流結(jié)構(gòu)模型，，本文對目前常見高度的樓層24層、18層、12層、9層、6層也進行了計算機數(shù)值模擬，驗證了優(yōu)化導(dǎo)流結(jié)構(gòu)模型的適用性，為以后的煙道設(shè)計和實驗研究提供了一定的參考依據(jù)。
[Abstract]:In recent years, high-rise buildings have become a common form of urban housing, and kitchen is an important part of housing, and the indoor air quality has been paid more and more attention. At present, the kitchen flue of high-rise residence mainly adopts the centralized smoke exhaust system of common shaft, which has problems such as the bottom oil fume can not be completely discharged, the series of smoke between the floors, pouring back and so on, and in the whole flue system, the exhaust smoke is not uniform. These phenomena make smoke and other harmful gases exist in the kitchen, causing great harm to human health. On the basis of domestic and international research, this paper further discusses, analyzes and studies the problems existing in the centralized exhaust gas system of high-rise residential kitchen. By means of experimental test and numerical simulation with computer, this paper analyzes and studies the smoke discharge system in the kitchen of high-rise residence, and explores the methods to solve the problems such as the smoke can not be completely discharged, the smoke string and the pouring back and so on. In this paper, two kinds of flue discharge systems with different sections in 33 layers are tested, and the measured data are analyzed. The characteristics of flue gas flow in the flue and the reasons for the poor smoke exhaust effect are compared and analyzed. On the basis of the experimental study, the numerical simulation of different cross section sizes of flue on different height floors (33n24 / 1818 / 129 / 6) has been carried out, and the appropriate cross section size of flue drain with different height has been determined. On the basis of the above research, combined with the smoke exhaust system model of the two experiments, the numerical simulation of the two experimental models was carried out, and the reasons for the problems such as insufficient exhaust volume and uneven exhaust gas were analyzed. The numerical simulation is used to optimize the two experimental models in different forms, that is, the vertical partition of the static pressure in the flue and the change of the form of the internal diversion components of the flue. The optimization scheme improves the existing problems to a certain extent. Combined with the analysis method of 33 floor flue system and the optimized diversion structure model, this paper also carries on the computer numerical simulation to the 24 / 18 / 12 / 12 / 9 / 9 / 6 floor of common floor at present, which verifies the applicability of the optimized diversion structure model. It provides a certain reference for the design and experimental study of flue in the future.
