Gas-liquid and liquid-liquid reaction experimental instrument based on up-and-down stretchable jet mixing

The invention provides a gas-liquid and liquid-liquid reaction experimental instrument based on up-and-down stretchable jet mixing. The experimental instrument comprises a reaction tank, a tank coverand a tank bottom seat, an up-and-down stretchable jet component is arranged in the reaction tank to jet liquid or gas reactants in up-and-down stretchable movement, mechanical stirring is combined with a jet effect to enable the reactants in the tank body to perform composite multidirectional movement such as up-and-down movement, clockwise and anticlockwise movement and tumbling, and contact area between the reactants is effectively increased, sufficient and uniform contact is realized, reaction is complete, and reaction rate can be effectively adjusted through mixing rate and feed flow rate, so that the reaction process can be conveniently observed by experimenters, mechanical and automatic operation reaction is realized, experimental data are accurate, and safety performance is high. 本发明提供种基于上下伸缩喷射混合的气液、液液反应实验
