固定管板式換熱器設計主要包括了以下幾個部分:工藝設計、結構設計、校核計算、繪圖。工藝設計主要是計算熱負荷、傳熱管數、管程數以及管子的排列等

摘要:    換熱器在工、農業的各領域應用十分廣泛,在日常生活中傳熱設備也隨處可見,是不可缺少的工藝設備之一。因此換熱設備的研究備受世界各國政府及研究機構的高度重視,在全世界第一次能源危機及在節約能源上研究新途徑。 換熱器是一種實現物料之間熱量傳遞的節能設備,是在石油、化工、石油化工、冶金、電力、輕工、食品等行業普遍應用的一種工藝設備。近年來隨著節能技術的發展,應用領域不斷擴大,利用換熱器進行高溫和低溫熱能回收帶來了顯著的經濟效益。
本課題設計了固定管板式換熱器。主要包括了以下幾個部分:工藝設計、結構設計、校核計算、繪圖。工藝設計主要是計算熱負荷、傳熱管數、管程數以及管子的排列等。結構設計主要是管箱、管板、法蘭、拉桿、膨脹節等。校核計算包括總傳熱系數、壁溫、壓力降和管板的強度校核。除此之外,還參閱相關的設計手冊及大量的文獻,完成了總圖和零件圖的繪制,還對外文進行了翻譯等工作。

Design of fixed tube-sheet heat exchanger
Abstract:     Heat exchanger with wide range of applications in the industrial and agricultural areas, heat transfer equipment can be seen in everyday life. It is one of the indispensable technological equipment. Heat exchanging equipment research around the world and therefore attached great importance to the Government and research institutions, in the first global energy crisis and conservation research on new ways. Between material is heat exchangers is a heat transfer and energy saving equipment, was in the petroleum, chemical industry, petrochemical industry, metallurgy, electric power, light industry, food industry, such as the universal application of a process equipment. In recent years, with the development of energy-saving technologies, expanding the field of application, use of heat exchangers for high and low temperature heat recovery bring about remarkable results.

This subject is design of fixed tube-sheet heat exchanger. Mainly consists of the following parts: process design, structure design, calculation, and drawing. Process design is the number of calculation of heat load; heat pipe, tube and pipe are arranged, and so on. Structural design mainly tubes, pipes, flanges, tie rods, expansion joints etc. Check calculation includes the total heat transfer coefficient, temperature, and pressure drop and tube-plate strength checks. In addition, referring the related design handbook and the massive literature, it has completed assembly drawing and detail drawing plan, and has carried on work and translations.
Keywords:    Fixed tube-sheet heat exchanger; Calculations; Strength calculation and checking
