Problems solved by technology

However, after the ceramic membrane equipment is cleaned with an oily solvent cleaning agent (such as food-grade caprylic glycerin), some water, wax, oxidative impurities and other components will be entrained in the oily solvent cleaning agent, and the color of the cleaning agent will become darker. Its ability to continue cleaning will gradually decrease

preparation example Construction

[0042]In the preparation process of viscosity-increasing modified superabsorbent resin, by adding acrylamide to superabsorbent resin acrylic acid, a small amount of hydrophobic groups can be introduced into the main chain of hydrophilic monomer polymerization to improve the salt resistance of superabsorbent resin The reason is that the hydrophobic association between the molecules of this kind of polymer makes the macromolecular chains cross-linked to form a space network structure with a certain strength, so that it has a large hydrodynamic volume and strong viscosity-increasing ability, and this The reversible spatial grid structure formed by the hydrophobic association has a strong ability to resist inorganic salts and temperature damage. In addition, the long-chain molecules extending from the surface of the superabsorbent resin particles have low density, interpenetrate and entangle with each other, so that the space network structure of loose agglomeration is formed betwe...

Abstract

The invention discloses a method for cleaning a ceramic membrane cleaning liquid containing oily substances, which comprises the following steps: adding an inorganic adsorption material to the cleaning liquid of a ceramic membrane, stirring and mixing evenly, and standing at 20-35°C for 5-7 days; The material is a mixture of activated carbon and viscosity-increasing modified superabsorbent resin; the inorganic adsorption material is separated from the cleaning liquid of the ceramic membrane to obtain a clear oily solvent cleaning agent. A method of cleaning liquid of ceramic membrane for treating oil-containing substances in the present invention is to absorb moisture and wax in ceramic membrane clear liquid by adding inorganic adsorption material containing activated carbon and viscosifying modified superabsorbent resin to the cleaning liquid of ceramic membrane , oxidative impurities and other components, so that the oily solvent cleaning agent in the ceramic membrane cleaning solution can be purified and regenerated, and the oily solvent cleaning agent after adsorption and removal of impurities can be recycled, thereby saving production costs and achieving the purpose of environmentally friendly production.

Description

technical field [0001] The invention relates to the technical field of cigarette essence and fragrance, in particular, the invention relates to a method for cleaning a ceramic membrane of an oil-containing substance. Background technique [0002] In the preparation process of cigarette flavors and fragrances, pure olive oil is usually used as the essential oil base oil. Since olive oil contains impurities such as insoluble waxes and oxidative impurities, in order to improve the quality of prepared flavors and fragrances, it is necessary to purify and remove impurities from olive oil. In production, ceramic membrane equipment is usually used to filter and remove impurities such as olive oil. [0003] Ceramic membrane equipment is an important link in the olive oil refinement process. The ceramic membrane equipment has high filtration accuracy, which can remove impurities and excessive waxy components of olive oil after cold pressing to the greatest extent, and improve the qu...
