回流冷凝器

The main factor which influences the heat exchange performance of air cooled condenser is the backflow or recirculation of hot air caused by the environmental big wind.

摘 要：影响空冷凝汽器换热性能的主要因素是环境大风所造成的热风回流或热风再循环。

Will withdraw, condense two output evaporations to get into the reflux congealed machine a hot and congealed liquid in the meantime, drop to withdraw in the bottle, is a new melting agent to add a medicine material noodles up, renew continuously solid-liquid two connect a people's layer, make the new melting agent is from the top to descend to pass a medicine material layer, have the dynamic state 渗漉 function, the dissolubility material which fuses a medicine material arrives to withdraw a bottle of bottom, and then gets into inspissation machine to carry on inspissation.

同时将提取、浓缩产生的二次蒸发进入回流冷凝器成热冷凝液，回落到提取罐中，作为新溶剂加到药材面上，不断更新固——液两相接口层，使新溶剂从上至下通过药材层，起了动态渗漉作用，溶解药材的可溶性物质到达提取罐底部，又进入浓缩器进行浓缩。

Use a Fluke non-contact thermometer to read the surface temperature of uninsulated steam lines, valves and fittings

用福禄克非接触式测温仪可读取非隔热蒸汽管道、阀门和接头、收集器以及冷凝物回流管的表面温度。

Operation analysis and investigation show that it is caused by the inappropriate design of hot vapor bypass control system, so the revamping has been carried out as follows: The diameter of hot vapor bypass pipeline has been enlarged from DN 40 mm to 80 mm, and the pressure difference of hot vapor bypass adjusting valve decreased from 50 kPa to 35 kPa; A vent pipeline for non-condensable gas fro.

改造的措施主要有：增大了热旁路管道的直径(由DN40mm增大到DN80mm)，并降低了热旁路调节阀的压差取值(由50kPa降低到35kPa)；增设一条自冷凝器壳程出口至回流罐的不凝气放空管道；对脱丁烷塔分程控制系统进行了改造，即将调节器输出信号的0-45%，55%%-100%分别用于控制热旁路调节阀和放空阀。

A reflux condenser is attached, and the mixture is boiled continuously for at least two and one-half hours.

回流冷凝器是重视和混合煮沸的不断至少有两个和一个半小时。

Apparatus— Use a 500-mL glass flask A connected by means of a trap B to a reflux condenser C by ground glass joints.

装置---使用一个与500ml的玻璃烧瓶A，与水分测定管B连接，使用磨口玻璃接头与回流冷凝器C连接

Plunder melds and run with this jewel!
