中心进气式油页岩干馏炉的冷态模拟优化
Cold model simulation and optimization for oil shale retort with central inflow
摘要
Abstract
During the continual operation of oil shale gas-heat-carrier retort, the flow distribution in the furnace has a significant impact on the oil shale retorting. The more uniform the distribution of the flow field in the pyrolysis section,the more positive impact on the oil shale retorting. In this paper,cold model simulation of CFD was used on the pyrolysis section of a self-designed retort with four-layer of intake. The advantages and disadvantages of this kind structure retort were analyzed and the corresponding shortcomings were improved. This kind of four-layer central inflow retort can provide better gas-heat-carrier filling and flow distribution as a whole. The entrance form was transformed into an inlet with cross vanes,which had a positive influence on the flow distribution in the retort. In this kind of structure, there was a problem that the gas filling degree was insufficient in the local area of the gas retort. Under the premise that the total gas intake was constant, adding the edge intake cooperate with the center intake in the specific position can fill the gas-heat-carrier retort better. The gas-heat-carrier in the pyrolysis section of the improved retort was more evenly distributed and ideal. The distribution of the gas-heat-carrier in the pyrolysis section of the improved retort was more ideal.关键词
