Description

Technical Field

[0001] The utility model relates to the technical field of acetic acid dehydration, in particular to an acetic acid dehydration device. Background Art

[0002] Glacial acetic acid, also known as acetic acid, is an organic compound and an organic monobasic acid, which is the main component of vinegar. Glacial acetic acid usually refers to pure anhydrous acetic acid, which is a colorless hygroscopic liquid with a low freezing point. After solidification, it is a colorless crystal with certain corrosiveness. The preparation of acetic acid can be done by artificial synthesis and bacterial fermentation. Biosynthesis, that is, the use of bacterial fermentation, is the most important method, especially for vinegar, because the food safety regulations of many countries stipulate that vinegar in food must be prepared by biological methods. Another method is to synthesize it from other chemical materials.

[0003] Generally, synthesized acetic acid is a mixed solution containing water. The presence of water causes a significant change in the properties of acetic acid. Therefore, if qualified glacial acetic acid needs to be prepared, dehydration operation is required. Generally, factories will choose the cheap room temperature drying method, which removes the water in the dehydrated solution through the normal evaporation of water. However, this method is extremely time-consuming and occupies a large area, which often leads to production costs far higher than the cost obtained. At the same time, some acetic acid is also mixed in the water, which will endanger human life safety. The second is the centrifugal dehydration method. In people's daily use, it is often found that the water after centrifugation is still mixed with some tiny crystalline particles. At the same time, the time required in the production process is also higher than the ideal time. In view of this, in-depth research was conducted on the above-mentioned problems, and this case was created. Utility Model Content
