Description

Technical Field

[0001] The utility model relates to the technical field of chemical experiments, in particular to a gas-liquid-solid three-phase reactor. Background Art

[0002] The three-phase reaction bottle is a commonly used instrument in chemical experiments. It is generally made of glass or iron. It is used for reactions of three different forms of reactants: gas, liquid and solid. It usually includes a bottle body with a feed port and an auxiliary equipment socket on the top and a gas feed port on the bottom. In actual use, the solid and liquid are first added to the bottle body and heated, stirred until evenly mixed, and then the gas is passed into the bottle body from the bottom. The gas is usually a substance with a low boiling point. It is liquid at room temperature and gaseous after entering the reactor. Since the volume of the liquid increases after vaporization, when the temperature in the bottle body is too high, a large vapor pressure will be generated. In severe cases, it will cause the liquid to boil violently and spray out from the gas outlet.

[0003] Solids can easily clog the gas phase inlet, hindering the entry of gas. Once clogged, the reaction needs to be terminated, the reactor needs to be disassembled and the gas phase inlet needs to be cleaned before the experiment can be started again. This will not only prolong the reaction cycle, but also waste reaction raw materials and increase reaction costs. Utility Model Content
