FRAAP’S Tube Reactor

 

概述/General Introduction

 

菲立管式反应器一种管状、在管内设置了很多混合的三维组件、使迅速达到反应和混合的连续操作反应器。这种反应器可以很长。反应器的结构有单管,多管并联空管不同形式,也可以是在管内填充颗粒状催化剂的填充管,进行多相催化反应。

FRAAPS Tube Reactor, in which a number of mixed three-dimensional components are placed in order to make reaction and mixture quickly, is a tube type continuous operation reactor. It could be very long. Its structure includes different forms with single tube, multi-tube parallel, empty tube, but also could be designed to filling tube, in which can full with granular catalyst for heterogeneous catalytic reaction.

 

反应物流处于湍流状态时,空管的长径比大于50;填充段长与粒径之比大于100(气体)或200(液体),物料的流动可近似地视为平推流。管式反应器返混小,因而容积效率(单位容积生产能力)高,对要求转化率较高或有串联副反应的场合尤为适用。此外,管式反应器可实现分段温度控制。

When the reactant flow is turbulent, empty tubes aspect ratio is more than 50; the length of the packed section to the particle sizes ratio is greater than 100 (gas)/200 (liquid),material flow could be approximated as a flat push flow. FRAAPS Tube Reactors back-mixing is very small, so volumetric efficiency is very high(per unit volumes production capacity),which especially suitable for applications requiring high conversions or tandem reactions. In addition, tubular reactors can segment control temperature.

 

特点/Characteristics


管式反应器具有以下特点:

FRAAPS Tube Reactors characteristics:

在正常情况下,它是连续定态操作,在反应器的各个径向截面上,物料浓度不随时间而变化; 

Under normal condition, it is a continuous steady state operation, the material concentration does not change over time in each radial cross-section of the reactor.

②反应器各处的浓度未必相等,反应速率随空间位置而变化;

The concentration of reactors may not be the same throughout the reaction rate varies with the location of the space;
由于径向具有严格均匀的速度分布,也就是在径向不存在浓度变化,所以反应速率随空间位置的变化只限于轴向。

Since radial has a strictly uniform velocity distribution, it means there is no concentration change in the radial direction, the change of the reaction rate with the spatial position is limited to the axial direction.
