Abstract

卧式高温热风炉，包括炉体、球床、冷风口、热风口，其特征在于炉体内的左右两侧分别设有燃烧室，炉体的底部位于燃烧室的下方装设有多个燃嘴，所述的冷风口设置在炉体的左侧，所述的热风口设置在炉体的右侧，且冷风口和热风口分别与炉体左右两侧的燃烧室相联通，所述的球床设置在炉体的中部，球床的两侧采用格子砖结构，中间加入高铝小球，球的直径为Φ10－Φ60mm，炉体的顶部开设有人孔。本发明减少燃料消耗，提高能源利用率。且可以提供更高的预热温度，在换热面积相同时，同时炉体也得以减小，因此本热风炉造价得以降低。本发明结构简单，投资少，换热效率高，容易用低热值煤气达到高换热温度，其换热效率可达80％。

Description

卧式高温热风炉
技术领域
本发明涉及一种卧式高温热风炉，是一种将煤气、蒸汽、空气等气体，经过高频换热，实现超高风温的换热装置。
技术背景
传统的热风炉，以现代高炉配套拷贝式热风炉和球式热风炉为代表的气体换热装置，上述换热装置热效率偏低，热风温度偏低，最高只能达到1250℃，体积庞大，一次性投资高，特别是用较低热值高炉煤气燃烧热风炉，难以获得高风温等不足。
发明内容
本发明是为了进一步节能，减少二氧化碳等温室气体的排放，特别为适应高炉工艺、煤气发生炉工艺对蒸汽、煤气、空气等气体高效换热需要而设计的一种卧式高温热风炉。
采用的解决方案是：
卧式高温热风炉，包括炉体、球床、冷风口、热风口，其特征在于炉体内的左右两侧分别设有燃烧室，炉体的底部位于燃烧室的下方装设有多个燃嘴，所述的冷风口设置在炉体的左侧，所述的热风口设置在炉体的右侧，且冷风口和热风口分别与炉体左右两侧的燃烧室相联通，所述的球床设置在炉体的中部，球床的两侧采用格子砖结构，中间加入高铝小球，球的直径为Φ10-Φ60mm，炉体的顶部开设有人孔。
本发明所述的卧式高温热风炉工作原理为：
在烧嘴内通如煤气和空气，燃烧后使球床温度升高，待球床温度升高至一定温度，然后停止加热，从冷风口引入待换热气体，低温气体经过球床，吸收球床热量，然后从热风口排出热风炉。当球床温度等于或低于换热温度时，停止冷风吹入，继续开始加热。
本发明具有如下优点：
1、采用蓄热式烧嘴加热，使烟尘排放温度低于150℃，减少了燃料消耗，提高了能源利用率。
2、本发明所述热风炉，不仅可以预热空气，也可以预热煤气或水蒸汽，同时也可以用于预热和重整其它可燃气体。
3、本发明所述的热风炉，可以提供更高的预热温度，温度可达1250-1450℃。
4、本发明所述的热风炉，因采用了比传统热风炉直径更小的小球(φ10-φ20mm)，在换热面积相同时，体积和重量缩小为原来的60-66％，同时炉体也得以减小，因此本热风炉造价得以降低。
5、本发明结构简单，投资少，换热效率高，容易用低热值煤气达到高换热温度，其换热效率可达80％。
附图说明
图1是本发明的一种实施例的结构示意图。
具体实施方式
实施例一
卧式高温热风炉，包括炉体6、球床4、冷风口1、热风口9，炉体6为方形，在炉体6内的左右两侧分别设有燃烧室2，炉体6的底部位于左右燃烧室2的下方分别安装有蓄热式烧嘴3，在炉体6的左侧开设有冷风口1，在炉体6的右侧开设有热风口8。球床4由格子砖隔墙8和小球7组成，小球7采用直径φ20mm的一级高铝球。炉体的顶部开有一人孔5。球床4内的小球7及格子砖隔墙8经加热，达到1500-1550℃后，空气经冷风口鼓入，空气经过球床4后，被预热到1250-1450℃，然后经热风口9通过管道送入反应器。
