Abstract

The invention discloses a high-temperature and high-pressure reaction kettle with controllable volume and pressure. According to the technical scheme, the high-temperature and high-pressure reaction kettle is characterized by comprising a reaction kettle cover, a reaction kettle body arranged at the lower end of the reaction kettle cover, a feeding valve and a diverter valve which are arranged onthe reaction kettle cover respectively, and a temperature measuring guide pipe penetrating from the upper end of the reaction kettle cover to the bottom of an inner cavity of the reaction kettle body;a thermocouple is arranged in the temperature measuring guide pipe; the reaction kettle cover is also provided with a safety valve and a pressure sensor which are respectively connected through a pipeline; and the lower end of the reaction kettle cover is sequentially provided with a first expansion boss and a first volume modulation assembly which are embedded into the inner cavity of the reaction kettle. An expansion kettle is additionally connected the outside the reaction kettle, so that the pressure in the reaction kettle which rises quickly along with the temperature can be relieved, and the initial pressure condition in the reaction kettle body is improved; the volume modulation assembly is selectively added in the reaction kettle body or the expansion kettle body to regulate and control the volume in the reaction kettle body or the expansion kettle body, so that the reaction kettle is suitable for reaction conditions of different scales and sizes, and the effect that one kettle has multiple purposes is expected to be achieved.

Description

technical field [0001] The invention relates to a high-temperature and high-pressure reactor with controllable volume and pressure, belonging to the technical field of reactors. Background technique [0002] The high-temperature and high-pressure reactor can achieve the effect of full contact reaction for solid, liquid and gas substances respectively. It is suitable for chemical experiments and industrial production fields such as petrochemical, metallurgy, fine chemical, fertilizer, medicine, food, seawater desalination, scientific research units, etc. . The volume of the traditional high-temperature and high-pressure reactor is fixed, which is limited by factors such as reaction materials and experimental environment, and there is a problem that the range of experimental capabilities is limited. [0003] At present, CN204583131U discloses a high-temperature and high-pressure reaction kettle with variable volume. Its temperature control is realized through the spiral pipe ...
