Description

一种高温烟气间接测温用水冷套换热器的高绝热保温结构
技术领域
本发明涉及一种测试装置的水冷套换热装置高绝热保温设计，尤其涉及一种高温烟气间接测温用水冷套换热器的高绝热保温结构设计。
背景技术
测试或研究用的水冷套换热装置的绝热性能对测试结果的准确性有很大的影响。在高温烟气温度间接测量领域，高温烟气与冷却水换热，通过测量冷却水通过水冷套的换热量，以及换热装置尾端烟气出口温度、流量，利用烟气放热和冷却水吸热的热平衡，反推高温烟气入口温度，理论上只有水冷套换热器对环境的散热损失为零才能保证严格的热平衡，因此，水冷套的绝热性能对炉膛高温烟气间接测温的准确性有很重要的影响，设计出一种水冷套换热器的高绝热保温结构，减少水冷套换热器对环境的散热损失，将提高高温烟气间接测温的准确性，基于同样的原因，水冷套的绝热性也将影响水冷套换热器在其它科研和测试领域使用的可靠性，进而间接影响测试结果的准确性。减少换热过程中冷却水套对环境的散热损失，确保烟气焓降计量的准确性，是提高高温烟气间接测温准确性及其它使用同样水冷套换热器的测试系统测量准确性必须要很好解决的问题。发明的水冷套换热装置的高绝热结构也可以应用于其他相关领域的绝热保温。
经过对现有技术的检索发现，目前尚未有一种方法或装置针对上述问题进行有效地研究并提出相应的解决方案。
发明内容
针对该领域存在的问题，本专利旨在提供一种用于高温烟气间接测温的高绝热水冷套换热装置，该装置具有高绝热的保温效果，极大程度的减少换热冷却水与周围环境的热量交换，保证了对水冷套换热器冷却水换热计量的准确性。
为实现上述目标，本专利采用如下技术方案。
提供一种外形呈圆柱形(或长方体形)水冷换热装置的高绝热保温结构，总体结构为三层夹空层结构，包括内表面镀银的带抽真空连接口的内夹层、中间回灌水夹层、填充岩棉绝热材料的外夹层。内夹层内表面镀银且带有抽真空连接口，极大程度的减少了整体保温结构的传热系数。回灌水源于水冷换热器出口水，根据是圆柱体形还是长方体形，回灌水夹层设置相应形式的导流板，以确保回灌水在夹层内均匀分布，其水温与换热器内冷却水水温基本相同且相互逆流，对水套换热器提供了近似绝热的保温效果。外层填充岩棉绝热材料进一步加强了对水冷套换热器绝热保温。通过三层夹空层结构的合理设计，使得本水冷套换热装置具有高绝热性能。
内表面镀银夹层厚度为10mm，回灌水夹层厚度30mm，保温材料填充夹层厚度为50mm以上，其内填充岩棉绝热材料。
夹层壳体及每层支撑材料均采用不锈钢钢板。
附图说明
图1为本发明专利一种高温烟气间接测温用水冷套换热器的高绝热保温结构示意图。
图1中：1-外层夹层；2-冷却水出口；3-中间回灌水夹层；4-夹层导流板；5-内层夹空层；6-回灌水出口；7-冷却水入口；8-壳体；9-水冷式换热装置；10回灌水入口。
具体实施方式
以下结合附图对本发明专利的原理及结构特征进行描述，所举实例只用于解释本发明，并非用于限定本发明的范围。
如图1所示，一种高温烟气间接测温用水冷套换热器的高绝热保温结构，该绝热保温结构的三层夹空层包裹在水冷套管式换热器9外围，所述三层夹空层的内层5内表面镀银，中间夹层3回灌换热器9冷却水出口2流出的冷却水，回灌水由回灌水入口10流入中间夹层3并由回灌水出口6排出，回灌水与水冷套换热器9内冷却水相互逆流，外层夹层1填充岩棉绝热材料。
所述内层5内表面镀银夹层厚度为10mm。
所述中间回灌水夹层3厚度30mm，回灌水夹层3采用导流板4使回灌水在夹层内分布均匀。

为缩短系统达到绝热保温过程的平衡时间，在设备开始运行初期，回灌水夹层入口可接恒温水箱，设备运行一段时间后再接入冷却水出口流出的冷却水进行回灌。
本专利一种高温烟气间接测温用水冷套换热器的高绝热保温结构也可用作其他设备的高绝热保温。
