Description

一种水合物生成及样品制备反应釜部件 技术领域
本发明涉及水合物生产及制备技术领域，尤其涉及一种水合物生成及样品制备反应釜部件。
背景技术
气体水合物是一种笼型结晶化合物，不同的客体分子如CH 4，CO 2，N 2，H 2等气体与水在低温和高压的条件下可以形成不同类型的气体水合物。利用水合物的笼型结构以及各种客体分子形成水合物条件的不同，可以将水合物应用在不同的工业技术领域。但是，水合物的基础研究需要对水合物样品进行测试分析和表征，而水合物样品的表征是需要利用相关设备对不同样品进行全方位多尺度测试分析，这些多尺度的测试分析对水合物的样品要求比较高，需要生成的水合物样品具有致密均一性，因此水合物样品的反应过程则需要水与气体反应完全。
目前常见的水合物样品反应装置都集中在釜内搅拌的方式，例如机械搅拌、磁力搅拌以及顶部喷淋等，这些方式能有效增加液体与气体的接触面，在一定程度上能促进水合物的生成，但是都存在一定的弊端。例如，对搅拌方式来说，当水合物生成速率较快时，搅拌会卡住而停止，而且旋转叶片和搅拌子的存在会影响水合物样品的致密性和均匀性；对顶部喷淋来说，在初期液体的喷淋可以促进水合物的生成，但是喷淋的液体量是固定的，当反应所需的液体喷淋完毕后，顶部喷淋的促进作用则基本消失。
发明内容
