摘　　要：基于实验室自行研制的一套喷射循环反应器进行水合物快速生成的实验。系统核心部件为由射流器和静态混合器组成的气泡发生器,通过控制气体循环速度的变化可控制气泡流流型。水合物生成实验始终保持喷射器处于自由抽吸状态,流态为高速向上的喷射型。采用静态混合器的情况下,喷射装置产生的微气泡可以极大地缩短水合物生成的诱导时间,但会降低水合物的生成速度,由于采用静态混合器增加系统背压,造成气体循环速度减小。经过对实验数据的进一步分析得出:喷射反应器中水合物的生成速度主要依赖于过冷度、气体循环流量、压力等因素;射流反应器生成水合物的方法与其他方法相比具有明显的优越性。A set of jet loop reactors has been developed for laboratory tests on rapidly generating NGH. This laboratory system mainly consists of ejector jet pump and a bubble generator made up of static mixers, in which bubble flow types can be controlled by the adjustable rate of gas recycling. During the process of NGH generation, ejector jet pump is working without control and fluid jet always kept upward at high speed. Under the condition of mixers, tiny bubbles from jet pump shortened the inductive phase time, but reduced the rate of NGH generation because gas cycle rate decreased by pressure burden on the whole system due to static mixers. Through analysis on laboratory data, this paper concluded that the rate of NGH generation in this self-developed system mainly depends on the degree of over-cooling, the quantity of cycling gas, and pressure, etc., and this system has been proved to be more advantageous than the other previous methods indoors.
