Continuous reaction desktop grade fixed bed

Abstract

The invention discloses a continuous reaction desktop grade fixed bed, which comprises a control cabinet, a continuous reaction structure, and a support structure. The control cabinet comprises a first gas source inlet, a second gas source inlet, and a third gas source inlet. The first gas source inlet, the second gas source inlet, and the third gas source inlet are all connected to an MFC gas flow controller. The continuous reaction structure comprises a reaction cabinet, a reactor, a water cooler, and a product collection device. One end of the reactor is connected to the MFC gas flow controller through a mixed gas inlet pipe. The other end of the reactor is connected to the water cooler. A reactor bed layer for storing a catalyst is arranged in the reactor. The support structure comprises a support column and bed legs. The support column is connected to the bottoms of the control cabinet and the reaction cabinet. Mixed gas flows into the reactor at a certain flowing speed and participates into the reactions, the volume is small, and the reactor is suitable for reactions with a large thermal effect, in particular, rapid reaction / serial reaction systems having high requirements onthe conversion rate.

Description

technical field [0001] The invention relates to the field of continuous reaction equipment, in particular to a desktop-level fixed bed for continuous reaction. Background technique [0002] The continuous reactor is a continuous operation reactor with a tubular shape and a relatively large length and diameter. Its structure includes single straight tube, spiral tube, and multi-tube parallel connection. It can also be designed as an empty tube with a solid catalyst bed added inside. Fill tubes for multiple catalytic reactions. At present, the relevant domestic continuous reactor equipment has a large volume, cumbersome reaction process, troublesome control, waste of manpower and material resources, and low production efficiency. [0003] As a common continuous reaction equipment, fixed-bed reactors are mostly floor-standing in the market, with a large volume. It is difficult to popularize in scientific research institutions with low production requirements, and the operation...

AI Technical Summary

Problems solved by technology

At present, the relevant domestic continuous reactor equipment is relatively large in volume, cumbersome in the reaction process, troublesome in control, waste of manpower and material resources, and low in production efficiency.

[0003] As a common continuous reaction equipment, fixed-bed reactors are mostly floor-standing in the market, with a large volume. It is difficult to popularize in scientific research institutions with low production requirements, and the operation is not simple and clear enough.

The existing fixed bed control system is generally divided into temperature control, gas flow control, and pressure control. The control is relatively scattered and the operation is cumbersome. It is urgent to study the structure and control of the fixed bed reactor to promote its popularization in scientific research institutions.
