濾氣孔道 的英文怎麼說
中文拼音 [lǜqìkǒngdào]
濾氣孔道
英文
filter gas circuit-
The porous ceramics is composed of lots of bridge arch - shaped microspores that connected and well - distributed inside the material. when the fluid passes through these pores, the suspended matters, colloid particles and big molecular organic substances are withheld or absorbed to the inner surface of the pore, and result in filtration, purification adn even - dispersion, high strength, good resistance to abrasion, high temperature and corrosion, no pollution, long workinglife, and easy to regenerate, the porous ceramics are available for filtration and fluidization of variou gas and liquid
微孔陶瓷過濾介質由許多大小分佈均勻,相互連通的橋拱狀開口氣孔組成.當流體從這些氣孔中通過時,流體中的懸浮物質,膠體顆粒,大分子有機物等被截留,吸附在微孔道內,從而達到了凈化和過濾均勻化的效果.微孔陶瓷強度高,耐磨損,耐高溫,耐腐蝕,無污染,氣孔分佈均勻,使用壽命長且再生簡便,特別適用於各種氣,液過濾和流態化過程The porous ceramics is a line of ceramic materials with porosity ; the pores are communicated up to the surface of the ceramic body
是一類體內含有大量彼此相通並與材料表面貫通的孔道結構的陶瓷材料,可用於過濾與分離、布氣、催化劑載體、潔凈燃燒、消聲材料、隔膜材料等。A theoretical model for purification of waste gas of low concentration in trickling biofilter was established with simplifying, the polyhole filter in the trickling biofilter to a parallel plat plates passage covered with biofilm
摘要將生物膜滴濾塔內的多孔填料簡化?壁面覆蓋有生物膜的平行平板通道,建立了一個凈化低濃度有機廢氣的理論模型。In order to study the regeneration mechanism of dpf in detail, we still need a mathematical model of the channel unit, which present temperature field and the soot reaction rate of the channel. finally, it points out the influences of various factors to the regeneration process by computing the numerical solution of model under different boundary conditions and geometry parameters, such as the initial temperature, the gas flow rate, the oxygen concentration, the sediment quantity and the wall thickness of the filters, and so on. in this way, the paper provides theoretical guidance for optimization design of the dpf
首先研究了干凈壁流式過濾體的加熱特性,然後在加熱和燃燒理論的基礎上建立了微粒捕集器再生過程的數學模型,並對模型進行了數值計算,得到了捕集器內部的三維溫度場分佈以及溫度梯度分佈,結果與實驗值吻合較好,驗證了模型的正確性;為了詳細的研究微粒捕集器的再生機理,建立了孔道單元數學模型,得到了孔道內的溫度場分佈和微粒反應速率分佈;最後,通過求解模型在不同邊界條件和不同幾何參數下的數值解,分析了各種因素對再生過程的影響,如過濾體初始溫度、過濾體內氣流的流動速率、氧濃度、微粒沉積量以及過濾體壁面厚度,為微粒捕集器的優化設計提供理論指導。分享友人
