Description
技术领域technical field
本发明涉及一种新型测温装置。The invention relates to a novel temperature measuring device.
背景技术Background technique
在液膜传质传热研究过程中，需要对液膜的温度进行测量。液膜不同位置温度差别不大，如果使用多个测温元件进行测量，由于测温元件个体存在差异，会造成误差过大而测量不准的问题。In the process of liquid film mass transfer and heat transfer research, it is necessary to measure the temperature of the liquid film. The temperature difference between different positions of the liquid film is not large. If multiple temperature measuring elements are used for measurement, due to the individual differences of the temperature measuring elements, it will cause the problem that the error is too large and the measurement is inaccurate.
用同一个测温元件进行测量时，由于液膜是一个锥体，需要测温元件的测温点在水平和垂直方向进行立体调节，液膜的厚度只有100-200μm，且测温区域较小，采用手动方式很难保证测温点能准确测量到液膜上。When measuring with the same temperature measuring element, since the liquid film is a cone, the temperature measuring point of the temperature measuring element needs to be adjusted in the horizontal and vertical directions. The thickness of the liquid film is only 100-200 μm, and the temperature measuring area is small. , it is difficult to ensure that the temperature measuring point can be accurately measured on the liquid film by manual method.
另外，由于传质传热是一个动态过程，随着时间的前进，温度会有所变化，所以测温响应时间需要越短越好，以便于能加快多个点的测量速度，保证液膜上多个点的测量温度的时间一致性。In addition, since mass transfer and heat transfer is a dynamic process, the temperature will change with the progress of time, so the response time of temperature measurement needs to be as short as possible, so as to speed up the measurement speed of multiple points and ensure that the Time consistency of measured temperature at multiple points.
