Description

Technical Field

[0001] The utility model relates to the field of reaction kettle condensation structures, in particular to a multifunctional reaction kettle condensation structure used in the preparation of quaternary ammonium lanolinate. Background Art

[0002] In the preparation of quaternary ammonium lanolate, the reactor is a key piece of equipment. Its internal temperature control and condensation efficiency are directly related to the final product quality and production efficiency. To effectively control the temperature during the reaction and collect the generated vapor or volatile components, conventional reactors generally utilize a condensation structure that combines baffles and heat exchange tubes.

[0003] When installing this type of condenser structure, a combination of tie rods and spacer tubes is typically used to secure the relative position between the baffles and tube sheet. One end of the tie rod is screwed to the tube sheet, while the other end passes through the baffle and is secured with a lock nut, thus connecting the two. The spacer tube is fitted over the tie rod, with its ends respectively fitting against the tube sheet and baffle to control and maintain the desired distance between them, thereby ensuring the stability of the condenser structure and heat exchange efficiency.

[0004] However, the lack of effective positioning devices between the spacer tubes and the tubesheet and baffles makes them prone to tilting during installation, resulting in errors in the distance between the baffles and tubesheet, affecting condensation and heat exchange efficiency. Furthermore, over time, the cooling medium corrodes the bolted joints between the tie rods and tubesheets, weakening the connection strength between the baffles and tubesheets, reducing the stability of the baffle installation, and ultimately shortening the baffle's service life.
