Description

Technical Field

[0001] This application relates to the field of light stabilizer production technology, specifically to an oil-water separation device for light stabilizer production. Background Technology

[0002] Light stabilizers are additives used in polymer products (such as plastics, rubber, coatings, and synthetic fibers). They can shield or absorb ultraviolet energy, quench singlet oxygen, and decompose hydrogen peroxide into inactive substances. These functions allow the polymer to eliminate or slow down photochemical reactions under light radiation, preventing or delaying photoaging and thus extending the lifespan of polymer products. The production process of light stabilizers involves free radical polymerization, solvent extraction, and crystallization purification, often generating large amounts of oily wastewater. Therefore, oil-water separation equipment is needed for light stabilizer production.

[0003] Patent CN219043109U discloses an oil-water separation device for chemical production. This device filters and blocks solid impurities in the oil-water mixture through a filter frame to prevent solid impurities from affecting subsequent oil-water separation. A stirring and defoaming mechanism thoroughly stirs the oil-water mixture and removes air bubbles during the stirring process. Stirring can improve the efficiency of oil-water separation, and the removal of air bubbles can improve the effect of oil-water separation. Air is supplied to the processing tank through an air conveying unit to facilitate the breaking down of the adhesion between oil and water and promote oil-water separation. The device has high oil-water separation efficiency and good effect, and is therefore more practical.

[0004] However, when the aforementioned oil-water separation device in chemical production supplies gas to the processing tank through the gas supply pipe connected to the gas pump, the gas supply time is relatively long due to the connection between the filter box and the processing box, which increases the processing cost and reaction time of the oil-water mixture treatment process.
