Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to an activated carbon filtering device for inositol production. Background Art

[0002] Inositol, also known as cyclohexanehexol, is an important vitamin required by higher animals. Inositol can promote fat metabolism and reduce the cholesterol content in the blood. It is also used as an anti-fatty liver drug for the treatment of cirrhosis, hepatitis, high cholesterol, excessive fat and vascular sclerosis. In addition to being used directly as a drug, such as inositol tablets, hepatol, and liver-soothing tablets, inositol is also used as a pharmaceutical intermediate to make many drugs, such as nicotinic acid inositol ester, Maitong, and the anticancer drug paclitaxel.

[0003] At present, in the process of producing inositol, activated carbon is mostly used to decolorize the inositol liquid. After decolorization, filtering equipment is generally used to remove the activated carbon in the liquid. Although the plate and frame filter has a large filtering area, it is easy to leak, which will cause activated carbon to be entrained in the liquid and pollute the product; and the plate and frame filtration process is open, and the heat loss is large. When the liquid temperature is lowered during filtration, crystals will precipitate, which not only causes material loss, but also easily causes pipeline blockage. In view of the above problems, it is necessary to provide a filtering device with high filtration efficiency, small heat loss, high filtration accuracy, and activated carbon that is not easy to leak.
