Reactor temperature measurement
Thread Content
The enamel reactor uses a frame-type agitator; a thermistor thermometer is inserted into the enamel sleeve in use, and there is heat transfer oil inside the sleeve. Since the sleeve cannot be inserted into the liquid surface, the temperature measurement is inaccurate. I hope to achieve accurate measurement of the material temperature. Do you have any good suggestions? Thank you
It would be best to have a picture of the reaction vessel, so as to determine where it is most suitable to install it; moreover, it’s not advisable to make holes in the enamel coating casually.
The temperature gun doesn’t work; there is foam on the upper part during the reaction. Thank you
Making holes is not very practical, as the enamel is prone to breaking.
1. On the outer surface of the reactor, in areas where there are no coils, surface temperature sensors should be installed. 2. To measure absolute pressure, the temperature is determined by referring to a gas-liquid equilibrium table in the PLC using the measured pressure value
1. Jacketed enamel reactors do not allow for the measurement of the surface temperature. 2. The reaction is at slightly positive pressure, and since the material is a mixture, an accurate conversion is not possible. Thank you
Why can’t the sleeve be inserted into the liquid surface? So what is the purpose of this sleeve?
The frame-type mixing is limited. Since the material is weakly acidic, a sleeve was added
Abroad, they are all made by ceramic sintering; in China, tetrafluoroethylene is generally used as the sleeve, and temperature measurement holes must be provided at appropriate locations; otherwise, a longer tetrafluoroethylene sleeve is required
