Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, and specifically relates to a filtering device for organic solvent production. Background Art

[0002] Organic solvents are a large class of organic compounds widely used in life and production. They usually have a small molecular weight and large volatility. Organic solvents are liquid organic substances that can dissolve some organic compounds insoluble in water. They are in a liquid state under normal temperature and pressure and have large volatility. The properties of the solute and solvent do not change during the dissolution process. During the production process of organic solvents, a filtering device needs to be used to remove impurities in the organic solvents to improve the purity and use effect of the solvent. The filtering device used in organic solvent production is provided with a filter plate in the form of microfiltration membrane filtration or ultrafiltration membrane filtration. The diameter of the small holes on the filter plate membrane (usually 1um to 0.1um) is used to control the interception of impurity particles. Impurity particles are likely to accumulate on the filter plate membrane, reducing the filtration efficiency of the filter plate membrane for organic solvents. If the filter plate membrane is directly replaced, the cost will increase. Therefore, this application proposes a filtering device for organic solvent production to solve the above problems.
