,"Hoy he estado viendoando la mayor parte de de los aclaramientos sobre tanques flash en el foro, personalmente no me siento muy claro,,

"La presiónión no es muy precisa con 257.8,,,a presiónión, y debería haber una gran diferencia con el diseño de tanques flash

"Ahora hacer una suposición de diseño, pigo a pedir consejo a los maestros. Existen tres flujos de agua condensada a diferentes presiones (de 0.6 11 1.5MPa, aquí tomemos

你都知道流速了,不就好算了嘛,把闪蒸罐看成一个大管道,有闪蒸蒸汽流量、密度、流速,不就可以算出截面积了(也就知道罐体直径了)

首先设计一个闪蒸罐需要知道二次蒸汽的流速,确定了流速之后,就确定了罐体的直径。然后根据液相的进料量,选择一个停留时间,根据停留时间,计算体积量,根据体积量可以计算液相的高度,二次蒸汽的分离一般需要1.5m以上的分离空间,根据以上几点,我们可以计算得到闪蒸罐的规格

就是这个停留时间不知道怎么去确定

实际上我确实按照气液分离罐计算了,而且现场情况也是气液混合的状态,但是我在想,如果说是按照题目所说,是不同压力的凝液进行降压闪蒸,这样的情况也能按照气液分离计算么?

按照停留时间计算其实是一个经验计算法,比较有依据的计算方法是按照传热面积来确定直径和高度!
