摘要:
为了实现改性双基推进剂制备过程中硝化甘油的安全输送和精确计量，利用乳化喷射器、直管质量流量计及数据处理器（PLC）对硝化甘油（NG）与水的混合液进行了连续加料与计量试验研究。利用Fluent模拟软件对NG的乳化喷液过程进行模拟分析，得到最佳的乳化喷射器结构参数为：喉管直径14.33 mm，喉管长度60.03 mm，喉嘴距12.00 mm;在此结构参数下进行模拟分析得到：乳化喷射器出口处NG最大体积分数小于30%，且所占节点比率小于0.05，说明NG与水混合均匀，确保了NG安全连续输送。研究了质量流量计在不同管道压力下对计量精度的影响，当管道压力为0.25～0.31 MPa时，能满足质量流量计的检测要求，计量误差≤1.0%，能满足改性双基推进剂连续制备的工艺要求。
Abstract:
In order to achieve the safe delivery and accurate measurement of nitroglycerin (NG) in the process of manufacturing modified double base propellant, three core innovations, emulsion ejector, straight tube mass flowmeter and PLC data processor, have been studied. The continuous addition and metering test on mixture of NG and water were carried out. Emulsification and spraying process of NG was simulated and analyzed by simulation software, FLUENT, from which the best structural parameters of the emulsifier were obtained: throat diameter is 14.33 mm, throat length is 60.03 mm, and distance between throat is 12.00 mm. Simulation analysis was performed under these structural parameters, and results show that the maximum volume fraction of NG at the exit of the emulsifying injector is less than 0.3 and the node ratio is less than 0.05, indicating that NG and water was mixed well to ensure the safety of continuous transmission of NG. Emulsifying injector, straight tube mass flow meter and PLC data processor were also applied in continuous addition and metering test of NG/water mixtures. Effects of mass flowmeter on the measurement accuracy under different pipelines pressures were identified. Pipeline pressure between 0.25 MPa and 0.31 MPa meets the requirements of mass flowmeter testing, and measurement error is no more than 1.0%, which meets the technical requirements of continuous preparation of modified double base propellant.
