Description

内波纹外鳍片空气预热器
本实用新型涉及一种空气换热设备,主要用于锅炉尾部受热面或其他场合气一气换热。
目前,传统的钢管式空气预热器,体积庞大,传热效果差,积灰严重,并且抗腐蚀能力差。
本实用新型的目的是提供一种结构紧凑,改善锅炉燃烧状况,传热效果良好,且抗腐蚀能力强的内波纹外鳍片空气预热器。
本实用新型是以如下技术方案实现的:上箱体设有进烟口,若干个鳍片管由隔板间隔定位装固在箱内。传热的鳍片管体内设有内波纹,管体外铸有外鳍片。上箱体一侧设有出风口。下箱体一侧开有进风口、下端开有出烟口。上、下箱体另一侧与转风室相连通。
本实用新型具有结构先进、紧凑、合理、传热效果好、改善锅炉燃烧状况、提高热效率、节约能源的突出优点。
下面结合附图对本实用新型作进一步详细说明:
图1是本实用新型主视剖示图;
图2是本实用新型鳍片管的主视剖示图。
图1~2是本实用新型具体实施例。上箱体1上端开有进烟口2,一侧开有出风口5,下箱体7一侧开有进风口6,下端开有出烟口8。上箱体1,下箱体7另一侧与转风室9相连通。40个传热鳍片管4由隔板3间隔定位装固在箱体内。传热的鳍片管4体内设有内波纹10,管体外铸有外鳍片11。
使用时,烟气从进烟口2进入,流经上箱体1、下箱体7中的传热鳍片管4,从出烟口8流出。冷空气从进风口6进入,流经下箱体7、转风室9、上箱体1,从出风口5流出。当冷空气在传热鳍片管外横向流动冲刷其管,大量鳍片可以扩大受热面积,使空气侧传热能力大大增强。当烟气在鳍片管内流动,内波纹可最大限度的破坏热阻较大的边界层。传热能力明显提高。同时合理选择烟气流速,在内波纹扰动下,几乎不存在积灰现象。传热能力加强,引起壁温增高,减少低温腐蚀,使锅炉烟气侧的热量合理利用。同时被加热的空气进入锅炉帮助燃烧,有利于改善锅炉燃烧状况,扩大其煤种适应性,提高效率,节约能源。
