一种卧式甲醛氧化器 技术领域
本发明涉及化工领域，具体为一种卧式甲醛氧化器。
背景技术
甲醛氧化器是生产甲醛的主要设备之一，氧化器的设计结构与甲醛成品的质量和氧化器的使用寿命有着密切的关系，在氧化器中的氧化反应中，氧化温度的变化是氧化反应中极其关键的环节，氧化反应中，反应温度过高会使得反应速度过快，从而导致副反应增多，杂质增多。一些甲醛氧化器在反应过程中，冷却速度较慢，产生的杂质较多，且因冷却速度慢，需增加换热速度，导致氧化器的直径较大，从而导致氧化器的单耗较大，产能较低。因此，我们提出一种卧式甲醛氧化器。

所述第三筒体18与第二筒体3、第一筒体2之间均设置有第一管板6，所述第三筒体18内设置有翅片管33，所述第三筒体18内设置有折流板9，所述折流板9套装于翅片管33的外侧壁，所述隔板1套装于翅片管33的外侧壁，所述氧化头7的内腔设置有催化剂层30、铜网31和筛板32，所述翅片管33的内腔设置有冷却水，所述翅片管33的左右两端分别与两组第一管板6连接。

在一种卧式甲醛氧化器使用的时候，反应气在氧化头7内腔中的催化剂层30上进行反应，反应生成的气体从筛板32上的筛孔逸出，卧式的甲醛氧化器结构，使得氧化头7与冷却结构分离，解除了传统的氧化器换热区与氧化区同直径造成的换热速度的限制，能较大的提高产能，便于拆卸与维修，第三筒体18上的两组氧化头7共同工作，能够将产量提高一倍以上，也可将一组氧化头7拆分为两组或多组，更便于制造和运输，矩形氧化头7的内部被分成几个部分将催化剂层30隔开，预防催化剂层30变形裂开，同时能够增大流通量，热量迅速进入冷却区域，防止氧化头7内部因较大产量而产生热量聚集，反应气经过筛板32下方的翅片管33预冷却，也利于保护作为换热管的翅片管33端部，位于第一管板6靠近第四筒体25的一侧的隔热板28，能够将管板与反应气隔离，防止反应气直接冲刷管板，而后反应气进入第二冷却腔5，经过第二管板8进入翅片管33和套管13之间的空隙，在对从翅片管33和套管13之间经过的反应气进行内外冷却时，反应气通过套管13与第二冷却腔5内的冷却水与翅片管33内的冷却水进行换热，此时翅片管33的内腔充满冷却水，套管13外侧壁与筒体之间上层为水汽，下层为冷却水，更利于换热，管板热区接触冷却水，管板高温区温度不会过高，能保持在不锈钢材料性能稳定使用范围内，翅片管33端部避开高温区，避免翅片管33温度过高造成翅片管33的端部损坏，从而提高设备使用寿命，反应产生的甲醛从甲醛出口23出排出，反应气经过第一冷却腔4、第二冷却腔5进行冷却，能够加速反应气的冷却，提高反应气冷却的效率，减少反 应所生成的杂质含量，将筛板32设置于翅片管33顶部的固定件，及氧化头7顶部安装的法兰，可以实现氧化头7的可拆卸功能，在灰尘、颗粒附着在翅片管33上时，更便于清洗，保持翅片管33的洁净，便于提高换热效率。
