The utility model discloses a heat exchanger, in particular to a shell and tube heat exchanger. A shell and tube heat exchanger with an inclined heat exchanger tube is provided. Including a tubular shell, which is characterized in that the cooling nozzle are respectively arranged at both ends of the upper and lower shell; cooling nozzle between the heat exchange tube to form a cooling water channel of the tube plate and the tube plate is connected, axes of the main part of the heat exchange tube and shell forms an angle; both ends of the shell ring butt welding set directly connected with a pipeline the loose steel pipe flanges. The heat exchanger has the advantages that can be directly added to the fluid in the pipeline, the fluid to complete the cooling effect in the flow process, the thread heat exchange tube increases the fluid contact with the cooling water area, and because of the heat exchange tube is installed obliquely relative to the vertical installation, the tube length is greatly increased, the heat transfer area increases, improve the effect of heat transfer, improve the utilization rate of cooling water. The utility model has the advantages of convenient disassembly and assembly, and is favorable for pipeline maintenance and heat exchanger cleaning.
【技术实现步骤摘要】
本技术公开了一种热交换器,特别是一种换热管倾斜设置的管壳式换热器。
技术介绍
目前最为常见的换热器,通常为板式换热器及管壳式换热器。管壳式换热器又称列管式换热器,壳体多为圆筒形,内部装有管束,管束两端固定在筒体两端的管板上,与筒体平行。这种结构导致冷流体在管内流动不均匀顺畅,封头与管箱的结构也较复杂,导致换热器不易清洗。对安装环境要求高,且会改变原有流体的流向及速度,对大流量工况不适合。
技术实现思路
针对现有的传统管壳式换热器的不足,本技术提供一种换热管倾斜设置的管壳式换热器。该换热器在换热管排列布置上特点,提高了冷却水的利用率,提高了换热效率,且适用于特殊工况,安装和维护也十分方便。本技术解决其技术问题的技术方案是:由管板和换热管构成冷媒通道,冷却水的进出口分别位于壳体上下两侧,换热管的轴线与筒体的轴线呈一夹角;壳体直接与管道通过对焊环松套钢制管法兰相连。所述的换热管为不锈钢换热管,材料为316L不锈钢,且换热管结构为螺纹管。换热管与壳体不平行,且呈5°-30°夹角。所述的换热管与管板连接处有工艺折弯。所述的壳体两端没有封头结构,直接与管道通过翻边法兰相连接。综上所述,一种换热管倾斜设置的管壳式换热器,包括圆管状的壳体,其特征是冷却水口分别设置在壳体上、下侧的两端;冷却水口之间由管板和连通管板的换热管构成冷却水通道,换热管主体部分的轴线与壳体的轴线呈一夹角;壳体两端设置直接与管道相连的对焊环松套钢制管法兰。所述的换热管为不锈钢换热管,材料为316L不锈钢,且换 ...
