[0002] In the fields of chemical industry, pharmaceuticals, biotechnology, etc., tubular reaction devices are widely used in various chemical reaction processes. Such devices usually include a support frame for fixing a plurality of reaction tubes arranged in parallel and connected in series at the head and tail. Catalyst inlet tubes are connected to the outside of each reaction tube. After the reaction fluid enters the reaction tubes, it flows through all the reaction tubes, is catalyzed by the catalyst, and finally flows out of the reaction tubes.

[0003] However, during the reaction, especially for reactions involving fluids, due to the turbulent flow characteristics of the fluid, irregular flow and pressure fluctuations often occur in the reaction tubes, which in turn cause the reaction tubes to vibrate. This vibration will be transmitted to the support frame, resulting in vibration of the support frame on the workshop floor and thus generating noise. To solve the above problems, the utility model proposes a tubular reaction device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a tubular reaction device to solve the problems put forward in the above background art.

A plurality of reaction tubes for the flow of the reaction fluid and the entry of the catalyst are symmetrically arranged on the top of the support plate, and the plurality of reaction tubes are arranged in a through manner from head to tail.

[0007] A buffer assembly symmetrically arranged on the opposite side of the fixed plate and the support plate. The buffer assembly is used to offset the vibration generated by the flow of the reaction fluid in the reaction tubes. The buffer assembly includes a movable sleeve. At the top of the movable sleeve, a connecting part for locking the support plate and the movable sleeve is provided. A resilient damping part is arranged in the inner cavity of the movable sleeve. The bottom of the movable sleeve is inserted through the top of the fixed plate, and an extrusion part for adjusting the stroke of the resilient damping part is provided at the insertion part of the movable sleeve and the fixed plate.

[0008] Preferably, the resilient damping part includes a compression spring arranged in the inner cavity of the movable sleeve. A limiting column for restricting the position of the compression spring is arranged at the top of the inner wall of the movable sleeve, and a damping ring is arranged on the outer side of the bottom of the movable sleeve.

[0009] Preferably, a friction cavity is formed at the intersection of the fixed plate and the movable sleeve, the damping ring is arranged inside the friction cavity, and the extrusion part is arranged at the bottom of the friction cavity.

[0010] Preferably, the extrusion part includes an extrusion column arranged inside the friction cavity and at the bottom of the compression spring.

[0011] Preferably, a limiting rod is arranged at the top of the extrusion column and in the middle of the compression spring. The limiting rod is used to limit the offset of the compression spring.

[0014] The technical effects and advantages of the present utility model:
