Description

Technical Field

[0001] The utility model relates to the technical field of concentrated sulfuric acid conveying, metering and dispersing, in particular to a concentrated sulfuric acid conveying, metering and dispersing device for producing 2-ketogluconic acid. Background Art

[0002] In the industrial production process of sodium D-isoascorbate, calcium 2-ketogluconate is the main intermediate. Acidification is an important production process. By adding sulfuric acid, calcium 2-keto-D-gluconate is converted into 2-keto-D-gluconic acid. At the same time, calcium ions and sulfate ions form CaSO4 precipitation to achieve the purpose of calcium removal. Otherwise, during the concentration and methanol recovery process, calcium-based oxides will form scale, which will not only affect the yield but also cause difficulties in subsequent treatment;

[0003] When it is used, in the process of producing 2-ketogluconic acid, it is difficult to control the amount of concentrated sulfuric acid during transportation, and the staff needs to measure in advance before unloading, which makes the staff's operation complex and the work efficiency low. After the production of 2-ketogluconic acid is completed, the staff needs to unload it and add it to the freezing tank, and separate it after freezing, which makes the staff have more work steps and makes the staff more time-consuming and labor-intensive. Therefore, we propose a concentrated sulfuric acid transportation metering and dispersing device for producing 2-ketogluconic acid. Summary of the invention
