摘要
为了保证50%双氧水热失控时在储罐中的安全泄放,利用VSP2(Vent Sizing Package 2)模拟了50%双氧水在带放空测试池中绝热条件下的热失控过程,得到了过程的温度、压力、温升速率变化情况,利用DIERS通用方法计算了50%双氧水安全泄放所需的放空口面积,得到了放空口面积的计算公式。结果表明,储罐设置足够的放空口面积可保证双氧水的安全泄放,在充装系数为0.8时所需的放空面积为0.005 2 V/m。
For the purpose of safe emergency relief for thermal runaway of 50% hydrogen peroxide, the thermal nmaway process of 50% hydrogen peroxide in vent seal is simulated by VSP＇2 and the temperature, pressure and temperature rising change has been obtained. The vent size for emergency relief of 50% hydrogen peroxide is valued using method DIERS, and the formula of calculating vent size is found. The results show that： the safe for emergency relief of hydrogen peroxide can be assured in tank by installing adequate vent area and the minimum vent area should be 0.005 2 V/m ff the substance is filled 80% volume in tank.
