Apparatus for verifying self-congestion behavior of sodium and carbon dioxide reactant and test method

The present invention discloses an apparatus for verifying a self-congestion behavior of sodium and a carbon dioxide reactant. The apparatus comprises an outer barrel, an upper flange, an air inlet pipe, an air outlet pipe, a spill-proof air chamber, a spill-proof rim and a reaction tube casing. The apparatus provided in the present invention is used for testing whether a sodium-carbon dioxide reaction product generates "self-congestion" is a printed circuit plate heat exchanger, and a test result is used for design of the printed circuit plate heat exchanger, to provide a basis for selectinga sodium side pipe diameter of the printed circuit plate heat exchanger, thereby reducing research and development costs of the printed circuit plate heat exchanger and improving application value ofthe printed circuit plate heat exchanger. 本发明公开了一种用于验证钠与二氧化碳反应物自堵行为的装置，其包括有外筒体、上法兰、进气接管、出气接管、防溢气腔、防溢裙边以及反应套管，通过利用本发明装置对钠-二氧化碳反应产物在印刷电路板式换热器中是否产生"自堵"进行试验，试验得到的结果将用于印刷电路板式换热器的设计中，为印刷电路板式换热器的钠侧管径的选择提供依据，从而降低了印刷电路板式换热器的研发成本，同时提升了印
