Description

一种锅炉用椭圆管换热器
技术领域
本发明涉及一种能源技术领域，一种尤其但不限于，与节能环保相关的技术，特别适用于锅炉节能环保技术领域。
背景技术
锅炉是利用各种燃料、电或者其他能源，将所盛装的液体加热到一定的参数，并对外输出热能的设备。传统锅炉尾部烟气温度高，这一部分的热能排到大气中，造成了能源损失。管式空气预热器由于结构简单，制造方便，已成为最常用的结构形式。由于空气预热器多处于烟气的低温区域，因此，积灰、腐蚀、磨损、振动是管式空气预热器最常见的故障，此外，由于管束均采取错列密集的布置形势，管束的流动阻力极高。因此，降低流阻，减轻积灰、腐蚀、磨损，防止振动，是设计空气预热器必须考虑的问题。就目前管式空气预热器存在的问题，则需要对椭圆管、椭圆管束的传热及流动特性进行较为深入地研究。
发明内容
针对上述现状，本发明的目的是提供一种锅炉用椭圆管换热器，椭圆管不仅能使传热强化，而且流动阻力极低，具有传统的强化传热技术不可比拟的优越性。
本发明的技术方案如下：
一种锅炉用椭圆管换热器，包括法兰(1)、管板(2)、椭圆管(3)、风机接口(4)、侧板(5)、扁钢(6)、角钢(7)、风接口(8)、抓钉(9)。
法兰(1)与角钢(7)对接焊接，法兰(1)与管板(2)相互焊接，法兰(1)与风机接口(4)螺栓固定连接，法兰(1)与风接口 (8)螺栓固定连接，管板(2)与椭圆管(3)相互焊接，风机接口 (4)与角钢(7)相互焊接，侧板(5)与风机接口(4)相互焊接，侧板(5)与管板(2)相互焊接，侧板(5)与风接口(8)相互焊接，抓钉(9)焊接于侧板(5)上，扁钢(6)与角钢(7)相互焊接。
所述的扁钢(6)其中一件从中间断开。
所述的抓钉(9)按统一间距均匀分布。
本发明的锅炉用椭圆管换热器，具有流动阻力小，传热系数大，传热面积大、传热周长比圆管大等特点，省去传统圆管容易积灰，腐蚀、磨损，提高效率等缺点，提高了锅炉的热交换性能，降低排烟温度和能量消耗，提高了锅炉热效率。

具体实施方式
下面结合附图和实施例具体说明本发明：
整个椭圆管换热器需配合锅炉或者其他供热设备使用，椭圆管换热器安放于锅炉尾部，烟气通过锅炉受热面后进入风机接口4,通过法兰1和角钢7的固定进入侧板5进行换热，高温烟气通过侧板5与进入由管板2固定的椭圆管3的空气进行换热，扁钢6与抓钉9起到固定协同作用，能降低烟气温度，从风接口8排放的烟气温度达到环保要求，另外进入锅炉前的空气进行加热，能提高炉膛温度，对锅炉燃烧起到很好的作用。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求书的保护范围为准。
