Description

Technical Field

[0001] The utility model relates to the technical field of adiabatic accelerating calorimeters, in particular to a device for preventing steam condensate from flowing back and an adiabatic accelerating calorimeter. Background Art

[0002] An adiabatic accelerating calorimeter is an instrument used to measure heat changes in chemical reactions. It utilizes the adiabatic principle, that is, experiments are conducted under conditions where no heat exchange occurs at a constant pressure. By conducting reactions under adiabatic conditions, the heat changes of the reactions can be accurately measured, thereby understanding the thermodynamic properties of the reactions. When using an adiabatic accelerating calorimeter to study liquid samples, when the temperature is higher than the boiling point of the liquid sample, part of the sample becomes steam, and the connecting pipe is outside the adiabatic furnace, where the temperature is close to room temperature and lower than the temperature inside the test pool, causing the steam to condense when cooled and flow back along the pipe into the test pool. The reflux liquid will cause additional heat changes to be introduced during the measurement process, and the instrument has a high sensitivity. Slight heat changes may cause the system to misjudge. Therefore, the utility model provides a device for preventing the backflow of steam condensate and an adiabatic accelerating calorimeter to solve the problems raised in the above background technology.
