METHOD AND APPARATUS FOR REMOVING RESIDUAL OF CHLORINATED SOLVENT FORMED DURING DRYING STAGE FROM CONTACT WATER IN DRY CLEANING MACHINE OF CLOTHES

摘要

PURPOSE: To provide a method and an apparatus for removing from contact water of residual of a chlorinated solvent resulting from the drying stage in a dry cleaning machine of clothes and solving an environmental problem caused by the abandonment of the contact water. ;CONSTITUTION: The contact water containing chlorinated solvent residual after decantation is evaporated, the vapor is irradiated with ultraviolet radiation, the chlorine-carbon bond of the solvent is destroyed and it is turned to a state harmless to environmental pollution and discharged into the atmosphere. This device for that is provided with an evaporation chamber 7, a means 9 for evaporating the contact water and the solvent residual and an ultraviolet ray lamp 12 arranged inside a housing 11 on the outside of a chamber communicated with the evaporation chamber through a window 10 closed by a quartz glass plate.;COPYRIGHT: (C)1993,JPO
