再沸器

The issue is expected to achieve the goal through the reboiler of the main components of the manufacturing process design, equipment manufacturing process to further understanding.

本课题预期达到的目标是通过对再沸器的主要部件制造工艺的设计，对设备制造工艺有进一步的了解。

A typical diagram is shown in Fig. 21.38 for a still with five ideal stages including the reboiler.

图21.38所示的是一个典型的包括再沸器具有5个理论级的McCabe－Thiele图。

A separated model is developed for the recirculating flow and heat transfer in a kettle reboiler tube bundle.

提出了釜式再沸器管束中循环流动换热的分相预报新模型，考虑了管束下部的过冷沸腾及循环液体的侧面引入。

Note that the tube pitch selected for the Reboiler is a deviation from the requirements of the Technical Appendix 3.1.3.9, but is necessary to ensure the optimum design for the units.

注意，为再沸器选定的管间距与技术附件3.1.3.9的要求有偏差，但对于保证该装置的最佳设计是必要的。

Note that the tube pitch selected for the Reboiler is a deviation from the requirements of the Technical Appendix 3.1.3.9, but is necessary to ensure the optimum design for the units.

说明一点，为再沸器选定的管心距的偏差应来自于技术附件3.1.3.9的要求，但仍有必要确保此处的最佳设计需求。

Mainly to do the following work:(1) E210 desorption tower reboiler manufacturing processes prepare the design: materials, including the acceptance, management, steel purification, orthopaedics, cutting, cutting, and so on.

主要做了以下工作：（1）E210解吸塔再沸器制造准备工序的设计：包括材料的验收、管理、钢材的净化、矫形、下料、切割等。

Title from Liaoyang Petrochemical 200,000 tons / year ethylene glycol project in the E210 desorption tower reboiler.

题目选自辽阳石化20万吨/年乙二醇项目中的E210解吸塔再沸器。

The reboiler duties and the hydrowax flow control are decoupled and do not interfere with each other allowing more stable and tight process control.

再沸器负荷和加氢蜡油流量控制是去偶的，不影响对方，使工艺控制更加稳定和紧凑。练习翻译？遇到难题？快来翻吧

The system may be operated to keep the top composition constant by increasing the reflux ratio as the composition of the liquid in the reboiler changes.

间歇精馏操作可以通过随着再沸器中液相组成的变化，逐渐增加回流比，以保持塔顶馏出液组成恒定。

If global air-failure and valve is kept as FC, steam to reboiler will fail close , reflux will fail open , hence likely that safety valve will not blow.

如果整体气源中断，而阀门保持FC，到再沸器的蒸汽将故障关闭，回流将故障打开，因此安全阀有可能不会打开泄放。

Compared the voltage negative feedback wire-feeding speed regulation system supported by current positive feedback with the rotational speed negative feedback regulation system, the equivalent condition of the two systems is obtained. Then, a wire-feeding speed regulation circuit for the CO_2 welding machine is designed based on TL494 chip, which has the self-protective function under the condition of current overloading.

通过对电压负反馈配合电流正反馈的送丝调速系统与转速负反馈调速系统的比较，得出了这两种调速系统的等效条件，并采用电压负反馈配合电流正反馈技术，设计了一种以TL494为核心的具有过电流截止保护功能的CO_2焊机送丝调速电路。
