Description

Technical Field

[0001] The utility model relates to the technical field of tubular reactors, in particular to a tubular reactor. Background Art

[0002] A tubular reactor is a continuously operated reactor in a tubular shape with a large aspect ratio, and belongs to a plug flow reactor. Since the tubular reactor has little back mixing, the volumetric efficiency (production capacity per unit volume) is high, and it is particularly suitable for occasions requiring a high conversion rate or having cascade side reactions. Therefore, in the prior art, tubular reactors are mostly used for reaction processing in the production and processing of N,N-disilyl-silaneamine (CAS13862-16-3).

[0003] A tubular reactor provided by publication number "CN220310449U" utilizes a buffer lower arc plate and a buffer upper arc plate to wrap the surface of the tubular reactor body to buffer and reduce vibrations caused by excessive flow of chemical liquids, thereby effectively buffering the vibration amplitude and noise of the tubular reactor, avoiding loose joints and leakage caused by the vibration of the tubular reactor, and ensuring the tightness of the connection of the tubular reactor body.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Although the tubular reactor can utilize the buffer lower arc plate and the buffer upper arc plate wrapped on the surface of the tubular reactor body to buffer and reduce vibration, the tubular reactor is not provided with a corresponding supporting structure to firmly support it, resulting in the tubular reactor being prone to overall shaking during use. At this time, the overall shaking of the tubular reactor will reduce the buffering effect of the buffer shock-absorbing structure, and the buffer lower arc plate and the buffer upper arc plate wrapped on the surface of the tubular reactor body are large in size, which will also affect the heat exchange effect between the tubular heat exchanger and the external air during actual use, and the practicality is poor.
