Description

technical field [0001] The invention belongs to the field of high-pressure reaction devices, and in particular relates to a pressure-controllable high-pressure hydration reaction device capable of performing hydrochemical reactions under high-temperature and high-pressure conditions. Background technique [0002] Most of the devices for carrying out the hydrochemical reaction process under high temperature and high pressure are high-pressure reactors (also called hydrothermal kettles), but the pressure of the commonly used high-pressure reactors is mostly self-boosting. During use, the pressure in the autoclave is significantly affected by the volume of the liquid in the container, the temperature of the liquid, and the properties of the liquid, and it is impossible to control the pressure, so it is difficult to control the speed and degree of the hydration reaction. In addition, due to the inability to control the pressure in the reactor, there are potential safety hazards ...

Problems solved by technology

During use, the pressure in the autoclave is significantly affected by the volume of the liquid in the container, the temperature of the liquid, and the properties of the liquid, and it is impossible to control the pressure, so it is difficult to control the speed and degree of the hydration reaction

In addition, due to the inability to control the pressure in the reactor, there are potential safety hazards during use. Often due to insufficient understanding of the nature of the reaction medium or improper use, the pressure in the reactor is too high, resulting in the explosion of the safety valve of the reactor or the lid of the reactor. occurrence of phenomenon
