中文拼音 [yāndàojiārèguǎn]
煙道加熱管
英文
smoke flue-
Firstly, simulate flow field of rear smoke channel, plot velocity magnitude and ash concentration distribution in section of entry of heat pipe air preheater, compare with data which were measured in guiyang power station, verify simulation to be reasonable and right. secondly, simulate all kinds of factors which affect flow field ' s uniformity such as length, thickness, location of diffluent board, ash concentration, ash diameter, and so on, find the chiefly factors. thirdly, install guide board in curve channel in rear smoke channel, then simulate its " flow field, plot velocity magnitude and ash concentration distribution
在此基礎上模擬在冬夏兩季不同情況下，不同流速對熱管空氣預熱器壁面溫度的影響；然後對影響整個流場分佈的各種因素：包括分流板長度、厚度、偏離中心流道位置的偏離度、飛灰濃度、飛灰粒徑等因素進行數值模擬；最後提出在分流煙道轉彎處加裝導流板，並模擬加裝導流板后的流場分佈，得到下級空氣預熱器出口、熱管空氣預熱器進口處的斷面速度場分佈、濃度場分佈，以論證加裝導流板能達到流場均勻化的作用。An integrated process of wastewater treatment and utilization is presented. the process is made up of heating the soft water of room temperature by high temperature printing and dyeing wastewater via heat exchangers, reusing the low level base decrement wastewater of water washing for dust control and desulphurizing of stack gas and anaeration - aeration biological treatment of printing and dyeing wastewater. this process has fair economical benefit on the principle of so called waste control by waste itself. this might be an ideal process for printing and dyeing wastewater treatment and disposal, the effluent of this process is quite enough to meet the requirement of urban sewer collector. additionally also many advantages are attractive such as the complete return of biological sludge to digestion, no chemicals dosage and free of secondary pollution
介紹了高溫印染廢水通過熱交換加熱常溫軟水、低濃度堿減量水洗廢水用於煙道氣除塵脫硫、厭氧-好氧處理一般印染廢水等印染廢水綜合處理技術，該技術具有較好的經濟效益，達到了以廢治廢的目的，生物污泥全部迴流硝化，不加任何藥劑，無二次污染，處理后水質達到城市截污管網標準要求，是一種較為理想的印染廢水處理工藝。For long - term protection of heated pipelines, exhaust pipes, smoke stacks and other heated surfaces up to 550 - 600
長期保護加熱管道、排氣管道、煙囪及其它溫度可高達550 - 600的受熱面。It is widely applied to the stove top, shove head, stove door and burmer brick, the binding of cooling - tube and groove bottom of the molten steel mouth of the heat stove, meantime empopyed in the field of the step stove bottom, the fir - proof wall of the circular stove, the cover, the protruding tape and sand sealing mouth of the equal - heating stove, the triangle, the spray gun and meltingiron groove of electric stove and also including fire - resistant material used in the refine stove and the stove door
加熱爐的爐頂、爐頭、爐門、燒嘴磚、水冷管包紮、出鋼槽槽底、步進爐爐底、環形爐檔火墻、均熱爐的爐蓋、凸出帶、砂封口、中間包包蓋、電爐三角區、鐵水包襯里、爐外精煉用噴槍，底吹氧煙道、鐵水溝蓋、檔渣堰、高爐中各種耐用火料襯里煉焦爐爐門等。Welded edge sheathed thermocouple is used to measure surface temperature of heat furnace pipe and smoke pipeline and widely applicable for oil refining, power generation, metallurgy, chemical fibre and food etc
刀刃式鎧裝熱電偶是用於測量加熱爐管和煙道管表面溫度的儀表，廣泛應用於煉油電力冶金化纖食品等There will appear a very uneven flow field, and appear a very big velocity magnitude distribution and ash concentration distribution near back wall. thus, the velocity magnitude is far bigger than that of optimal design velocity magnitude, which will lead to serious wear and tear in metal face of heater. especially, because of curve structure in front of heat pipe air preheater, there is more serious wear and tear
由於靠近豎井后墻面的煙氣流速很大，飛灰濃度也較大，斷面速度分佈的最大速度大於最佳設計速度的2 - 3倍，這樣將造成受熱面的嚴重磨損，特別是熱管空氣預熱器前端煙道的幾何結構有一定的轉角，更增加了磨損的程度。The progress of fires could be blocked by fireproof partitions and by ventilation systems that pressurize the floors both above and below the flames to contain smoke and heat, which would be vented out through exhaust shafts
防火隔間與通風系統都能阻滯火勢蔓延；通風系統可以在起火樓層上下加壓，將煙與熱氣聚在一處，再由排放管道排出。分享友人
