WORKBENCH-BASED METHOD FOR SIMULATING MULTI-COUPLING FIELD STRESS DISTRIBUTION OF LOW-TEMPERATURE CARBONIZATION FURNACE

摘要

A WORKBENCH-based method for simulating multi-coupling field stress distribution of a low-temperature carbonization furnace, relating to the technical field of design and analysis of a low-temperature carbonization furnace. Said method overcomes the defect that the stress characteristics of materials in different furnace chambers cannot be tested in a design stage of the low-temperature carbonization furnace, and comprises steps of: (1) establishing a three-dimensional simulation model by using a Design Modeler module in WORKBENCH software; (2) meshing the three-dimensional simulation model; (3) transferring a three-dimensional simulation model of a meshed fluid calculation domain to a CFX calculation module and setting same; (4) transferring a result obtained by a simulation operation to Steady-state-thermal and Static-structural for thermal stress calculation; and (5) under the same setting conditions, by setting different operating temperatures and airflow speed parameters and repeating steps (1) to (4), performing multiple simulation calculations. By determining the stress distribution state of the low-temperature carbonization furnace at different temperatures and airflow speeds, the present invention can predict the structural performance of the furnace chamber and the state of uniform distribution of the airflow, and use same to design the basis for the structure of the muffle chamber of the low-temperature carbonization furnace and operating process parameters.
