設計一種電脫鹽換熱器,在設計過程中,首先通過查詢大量文獻資料分析電脫鹽換熱器的結構設計、用途,從而根據實際工況從傳熱效率、結構、經濟等方面來選擇換熱器種類

摘要:換熱器是一種將熱流體的部分熱量傳遞給冷流體的設備,在現今生產制造過程中應用非常廣泛,特別在石油行業運用最為廣泛,但是剛開采出來的石油含有許多雜質和有害介質,為去除這些介質,現今采用電脫鹽技術。原油電脫鹽的原理就是在電場、破乳劑、溫度、注水、混合強度等因素的綜合作用下,破壞原油乳化狀態、實現油水分離的過程。本課題便設計一種電脫鹽換熱器,在設計過程中,首先通過查詢大量文獻資料分析電脫鹽換熱器的結構設計、用途,從而根據實際工況從傳熱效率、結構、經濟等方面來選擇換熱器種類,并結合電脫鹽技術對換熱器設計的影響進行計算, 主要是根據已經選定的換熱器型式進行設備內各零部件(如接管、折流板、定距管、管箱等)的設計,包括:材料的選擇、具體尺寸確定、確定具體位置、管板厚度的計算、開孔補強計算等。 34731

 The design of electric desalting heat exchanger
Abstract: Heat exchanger is the transfer of a portion of the thermal fluid heat to the cold fluid equipment,in today's manufacturing process is widely used,Most widely used especially in the oil industry,Heat exchanger is used most widely in the oil industry,but crude oil contains many impurities and harmful medium,In order to remove this,the desalination technology is now used. The principle of electric desalting of crude oil is in the electric field,temperature,demulsifier,water injection,mixed to a combination of factors,such as intensity,damage state of crude oil emulsion,to realize the process of oil-water separation .The subject has designed a kind of electric desalting heat exchanger,in the design process. Firstly,the structure design and the use of the electric desalination heat exchanger are analyzed by checking many documents,and the type of heat exchanger is chosen from the aspects of heat transfer efficiency,structure and economy according to the actual working conditions,and combined with the effect of electric desalting technology of heat exchanger design structure design. Mainly according to the heat exchanger type has been selected for each component in the design of equipment (e.g., take-over, baffle plate and spacer pipe, tube, etc.),including: the choice of materials,the determination of the specific size,determine the specific location,the thickness of the tube plate,opening reinforcement calculation,etc. 源¥自%六^^維*論-文+網=www.aftnzs.live
