UNIT FOR DRY CLEANING TEXTILE ARTICLES USING A COMPOSITE SOLVENT AND FOR RECYCLING THE USED COMPOSITE SOLVENT FOR RE-USE

摘要

The invention relates to a unit for dry cleaning textile articles using a composite solvent comprising multiple components, said unit including: a dry cleaning chamber (1) configured to mix the textile articles to be cleaned with the composite solvent during a cleaning cycle; a device (7) for recovering the used composite solvent after a cleaning cycle; a treatment device (8) for removing water and dirt and recycling at least part of the used composite solvent in order to use same in another dry cleaning cycle. The unit is characterised in that it also comprises a re-adjustment device (9) for re-adjusting the composition of the recycled composite solvent, incorporating therein at least the part of the component(s) that was lost in the treatment device (8), said re-adjustment device comprising at least: a buffer tank (10) provided with at least one supply inlet (10a) for the recycled composite solvent, at least one supply inlet (10b) for at least the part of the component(s) of the composite solvent to be introduced into the buffer tank (10) in order to re-adjust the composition of the recycled composite solvent, and at least one outlet (10c) for the re-adjusted and recycled composite solvent, said outlet (10c) being connected to the storage tank (5) for the dry cleaning composite solvent; a storage tank (11) for one or more components of the dry cleaning composite solvent; and a metering pump (14) for metering the quantity of the component(s) of the composite solvent to be introduced into the buffer tank (10) through the inlet (10b) in order to re-adjust the composition of the recycled composite solvent, said pump being linked upstream to at least one storage tank (11) containing one or more components of the dry cleaning composite solvent.
