Method for simulating oxygen content distribution of high-temperature carbonization furnace based on ANSYS

Abstract

The invention discloses a simulation method for oxygen content distribution of a high-temperature carbonization furnace based on ANSYS, and relates to the technical field of simulation test methods for the oxygen content distribution of the high-temperature carbonization furnace. The method comprises the following steps: S1, establishing a three-dimensional simulation model; S2, carrying out the mesh generation; S3, importing a FLUENT module of the ANSYS software; S4, setting a detection point and a detection surface, carrying out simulation operation to obtain a simulation result, and takingthe simulation result as an index for designing a muffle cavity structure and an inlet and outlet sealing structure of the high-temperature carbonization furnace; S5, repeating the steps S1 to S4 according to different parameters, so as to carry out the simulation for many times. A temperature change curve of a detection point in a furnace chamber, a temperature cloud chart of a detection surfaceand an airflow speed cloud chart of the detection surface are used as indexes for evaluating the hearth heating effect and airflow and distribution characteristics, so that the optimal hearth heatingcapacity and airflow distribution design are determined. The structural design can be better measured, and the design cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of a simulation test method for oxygen content distribution in a high-temperature carbonization furnace. Background technique [0002] Carbon fiber production is a high-energy-consuming industry. The high-temperature carbonization furnace is one of the largest energy-consuming households in carbon fiber production equipment. Compared with the low-temperature carbonization furnace, the high-temperature carbonization furnace generally refers to the high-temperature range: 1000°C-1600°C . The high-temperature carbonization furnace is also a key equipment for carbon fiber production, mainly used for high-temperature carbonization of pre-oxidized filaments to convert them into carbon fibers with a carbon content greater than 90%. High-temperature carbonization furnace is an integration of high-temperature technology and high-temperature equipment, and the operating temperature is generally 1000°C-1600°C. Accord...

Problems solved by technology

However, at present, carbonization furnaces can only be produced by enterprises in a few countries such as Germany, the United States, Japan, and Russia, and the purchase price is high. Moreover, as special equipment, the import of carbonization furnaces is subject to export controls by various countries, making its use and consumption restricted. extremely restrictive
