Abstract

PURPOSE:To completely remove the solvent in waste water and to perfectly separate water emulsified in the solvent, by enhancing the decomposition capacity of water and the solvent by using a hydrophobic filter material comprising a non-polar resin and ceramics. CONSTITUTION:A solution mixture consisting of a solvent, water and a surfactant is at first injected in a hydrophobic filter material 8 from an injection port 5 and water 6 is inhibited from permeation to the outside of the filter material 8 and remains therein while the solvent 7 is separated by the filter material 8 and permeated through said filter material to be transferred to the outside thereof. The separated water 6 is discharged out of a dry cleaner from a water outlet 9 and the solvent 7 separated by the filter material 8 is recovered in a clean tank from a solvent outlet 10. As the filter material 8, one prepared by coating biscuitware comprising polytetrafluoroethylene, polyethylene, polypropylene or alumina ceramics with a phenol resin is pref., used.

回収され、水分離器に入って溶剤と水を分離している。Dry cleaners that use chlorinated solvents can remove oil-soluble stains from clothing, but it is difficult to remove water-soluble stains. Therefore,
Conventionally, a surfactant is used to emulsify water in a solvent, and this water is used to remove water-soluble stains. Also, at the end of the distillation process of the washing liquid (mixed discrete mixture of chlorinated solvent, surfactant, and water) after washing clothes, steam is sometimes blown directly into the distiller to accelerate the distillation. The water introduced into the machine in this way is distilled - [Step C is a condenser, and in the drying process it is condensed and liquefied as a mixture of bamboo powder, which is recovered and sent to a water separator. It separates the solvent and water.

らＪｕｌｌ出さイＬる。In conventional water separators based on the difference in specific gravity, the water emulsified in the solvent by the solvent and surfactant mixed in the water is not completely separated due to the difference in specific gravity, and the former is directly discharged outside the machine.
The wastewater discharged was accompanied by a solvent odor, which had an undesirable impact on local residents. On the other hand, the latter causes an increase in the amount of water contained in the solvent, which causes the clothes to become unstable.

In other words, the solvent mixed on the water side moves to the outside due to rancidity, and The water emulsified in the solvent is prevented from migrating to the outside by the filter medium and remains inside the algae, free of foreign components and resulting in rapid moisture MtM nJ performance.
