Description

Technical Field

[0001] The utility model relates to the technical field of hydrogenated dimer acid production equipment, and more specifically, to a heat exchanger for refined materials of hydrogenated dimer acid. Background Art

[0002] Hydrogenated dimer acid is a product obtained through chemical reactions and is usually used in the production of lubricant additives, resin modifiers, surfactants, etc. The refining process is to further purify and process the initial product to remove impurities and improve the product purity and performance. The heat exchanger plays a key role in temperature control during this process;

[0003] The heat exchanger for refined materials of hydrogenated dimer acid is a device used in chemical processes and is mainly used for heat exchange in the production process of hydrogenated dimer acid. During this process, the role of the heat exchanger is to cool or heat the hydrogenated dimer acid material through heat exchange to meet the specific temperature requirements of subsequent process steps {such as the "coiled tube heat exchanger" in the publication (publication) number: CN220460646U, an inclined reaction kettle with a heat exchanger that can be quickly disassembled} for use;

[0004] For the above-mentioned "coiled tube heat exchanger", the coiled tube part is built into the "reaction kettle", and the other part of the coiled tube passes through the outside of the "reaction kettle". When it is applied in the production of hydrogenated dimer acid, there are disadvantages such as poor anti-corrosion effect, and insufficient heat preservation of the transmission medium outside the coiled tube, resulting in large energy consumption and waste.
