AI Technical Summary

Technical Problem

In existing fixed-bed reactors, temperature measurement cables are prone to deviating from the center, resulting in distorted temperature data. Furthermore, existing fixed devices interfere with catalyst loading and reaction uniformity.

Method used

Multiple sets of symmetrically arranged tension retainers are used. The temperature cable is squeezed by the inclined springs and external fixing structure to ensure that it is vertically arranged in the center of the reactor. The external fixing and springs, made of inert material, provide power.

Benefits of technology

This effectively avoids temperature cable adhesion errors, ensures accurate temperature measurement, and does not interfere with catalyst loading and reaction uniformity.

Description

TECHNICAL FIELD

[0001] The utility model relates to the field of furfural production, especially to fixed temperature measuring device inside fixed tube. BACKGROUND

[0002] Fixed bed reactor is the common reaction device of furfural production, when carrying out furfural production operation, if adopting fixed bed reactor, must carry out accurate measurement to the catalyst temperature inside fixed bed.

[0003] Because catalyst is usually solid, so cause the heat conduction performance of catalyst to be often poor, in addition to the length of fixed tube is longer, and the probe is easy to deviate from the central position and close to the pipe wall, when the temperature measuring cable probe goes in the fixed tube inside and carries out temperature measurement, just easy to be distorted, mainly will cause the temperature data that temperature measuring cable measured can not truly reflect the actual temperature of fixed tube center.

[0004] Especially, most of the current temperature measuring cables are multi-node temperature measuring cables.

[0005] If the temperature measuring nodes at different heights are not fixed properly, the temperature probe deviating from the center and close to the wall will be more serious.

[0006] One of the prior art is to use a fixed plate, but the fixed plate will interfere with the catalyst loading process, and the fixed plate will also adversely affect the uniform distribution of the subsequent reaction system.

[0007] Therefore, it is urgent to develop a new device that can fix the temperature cable.
