Control and Use of High Pressure Reactor Temperature
A high-pressure reactor refers to a type of reactor operated under high pressure, and temperature is very important for the high-pressure reactor. Excessive or insufficient temperature can affect the reaction. So it is important to control the issue of the high-pressure reactor during the reaction process, and also pay attention to some issues during use.
The high-pressure reactor belongs to high-temperature and high-pressure products, so a protective sleeve is installed when installing the thermometer. The protective sleeve serves a protective function, equivalent to isolating the thermometer from the material during the operation of the high-pressure reactor. The protective sleeve itself has a wall thickness, and the heat of the material can only be transferred to the sensing rod of the thermometer through the wall thickness of the protective sleeve. The thicker the wall thickness, the slower the transfer process, resulting in a discrepancy between the measured temperature and the actual temperature.
A high-pressure reactor is a reaction vessel with high-pressure operation, typically connected to high-temperature working conditions. So, in addition to controlling the pressure condition during operation, heating and cooling are also areas that require special attention. So:
- The high-pressure reactor should not be heated too quickly or cooled rapidly during operation to prevent excessive temperature changes from causing cracks in the reactor body.
- If the high-pressure reactor is equipped with a magnetic stirrer, it is necessary to introduce cooling water into the stirrer when the temperature reaches over 100 degrees during the reaction process to avoid damaging the stirrer due to excessive temperature.
- After the reaction is complete, cool down first, then release the high-pressure gas in the high-pressure reactor to reduce the pressure to atmospheric pressure, and then symmetrically and evenly loosen and remove the main bolts.
