请帮忙翻译 谢谢 多效蒸发？ the partially concentrated liquor and the generated vapor leave the tubes at the bottom. the liquor collects in the lower liquor chamber, where most of it flows to p-2 circulation pump and re-circulates to the top tube sheet. the excess liquor enters an internal over-flow pipe in the bottom of the c-1 lower liquor chamber and flows by gravity and vapor pressure difference to the second effect. this pipe connects to the recirculation suction piping of the second effect evaporator (c-2). this connection is located at least 4 meters below the operating level of the second effect so that the hotter transfer liquor is suppressed from flashing. 翻译如下： 部分酒精浓缩液和绝大部分二次蒸汽从底部离开加热管。 酒精汇集到下级酒精室，他们中的大部分在这里流入p-2循环泵再循环回顶部管板。多出的酒精进入一个在c-1下级究竟是底部的内部过流管，根据重力和二次蒸汽压力的不同流入第二效体。 这个管道接入第二效蒸发器（c-2）的吸入管道。为防止更热流入酒精闪蒸，此连接处至少低于第二效工作液位4米。 希望有帮助，请大家指正。查看更多
