液态CO2防灭火管路输送特性影响分析
Influence analysis of liquid CO2 fire extinguishing pipeline transportation characteristics
-
摘要: 管道输送液态CO2不仅可以进行煤矿火灾防治，还能将温室气体CO2有效储藏到地下，符合当前全球经济发展模式。由于矿井环境温差和巷道倾斜等原因，管道不可避免地会发生热交换还会产生较大压降；为了避免液态CO2在输送过程中发生相变，有必要考虑环境温度、风速、保温棉、管道倾角和地形海拔等因素，以确保安全、经济高效的运输；基于商业模拟软件ASPEN HYSYS V8.4对管道输送CO2过程进行模拟。结果表明：环境因素中管道倾角对于CO2输送过程影响很大；对于公称直径为32 mm的管道，流量设置为2 500 kg/h最有利于液态CO2输送。Abstract: Pipeline transportation of liquid CO2 can not only prevent coal mine fires, but also effectively store greenhouse gase CO2 in underground, which is in line with the current global economic development model. Due to the temperature difference of the mine environment and the inclination of the roadway, heat exchange and large pressure drop will inevitably occur in the pipeline. In order to avoid the phase change of liquid CO2 during transportation, it is necessary to consider factors such as ambient temperature, wind speed, insulation cotton, pipeline inclination, and terrain elevation to ensure safe, cost-effective transportation. Based on the commercial simulation software ASPEN HYSYS V8.4, this paper simulates the process of liquid CO2 transportation. The results show that the inclination of the pipeline has a great influence on the CO2 transportation process among environmental factors and is conducive to liquid CO2 transportation.
