DYHGGY-11 Residence Time Distribution and Reactor Flow Characteristics Determination Training Platform
Release time：2024-06-15 07:00viewed：times
Device function:
1. Compare and study the residence time distribution and flow characteristics of kettle and tubular reactors.
2. Analyze and study the residence time distribution and backmixing degree of kettle and tubular reactors through the parameters of the multi-kettle series model . The model parameter N represents the backmixing degree of the reactor. The larger the N, the smaller the backmixing degree, and then guide students to understand the two ideal modes of plug flow and full mixing flow.
3. The device can be operated with no circulation and variable circulation ratio R respectively, and the residence time distribution of tubular reactors can be determined under different backmixing degrees.
4. The device uses the pulse tracer method to determine the residence time distribution. The conductivity meter can accurately detect and record the concentration of the tracer at the outlet of each reactor in real time, and obt*n various parameters through software processing.
5. Full touch integrated control, high-stability data transmission, hardware encryption.
