Abstract
In an installation comprising a solvent regeneration circuit and a solvent recovery circuit, each solvent container is connected independently to the boiler of a distillation unit for cleaning purposes. The relative arrangement of the solvent containers is such that the solvent circulates under the action of gravity from a condenser to the boiler and from each container to the boiler. The boiler is removable for subsequent disposal after filling with solvent residues and waste materials.
Claims10
An installation for cleaning clothes and removal of oarticulate contaminants especially from clothing contaminated by radioactive particles, of the type which operates under atmospheric pressure in a dry-cleaning solvent medium, comprising a cleaning tank which is interposed on the one hand in a solvent regeneration circuit of the type consisting of a distillation unit, a condenser, a water separator, a solvent reservoir, and which is interposed on the other hand in a solvent recovery circuit of the condenser type for recovering the solvent entrained by the drying air, wherein each solvent container, namely the condenser, the water separator, the solvent reservoir of the solvent regeneration circuit and the condenser of the solvent recovery circuit, is connected independently and directly with interposition of a valve to the boiler of the distillation unit for cleaning purposes.
An installation for cleaning clothes and removal of particulate contaminants especially from clothing contaminated by radioactive particles, of the type which operates under atmospheric pressure in a dry-cleaning solvent medium, comprising a cleaning tank which is interposed on the one hand in a solvent regeneration circuit of the type consisting of a distillation unit, a condenser, a water separator, a water recovery reservoir which is placed downstream of the water separator and is directly connected to a boiler, a solvent reservoir, and which is interposed on the other hand in a solvent recovery circuit of the condenser type for recovering the solvent entrained by the drying air, wherein said recovery circuit comprises a cooler-bank recovery unit for condensation of the solvent vapors, the solvent recovery unit being connected upstream of the water separator of the solvent regeneration circuit, wherein each solvent container, namely the condenser, the water separator, the solvent reservoir of the solvent regeneration circuit and the condenser of the solvent recovery circuit, is connected independently and directly with interposition of a valve to a disposable boiler of the distillation unit for cleaning purposes, said boiler being removably mounted on said distillation unit, wherein the relative arrangement of the different containers is such that circulation of the solvent takes places under the action of gravity from the condenser to the boiler and from each solvent container to said boiler, and wherein the boiler opening is sufficiently large to permit introduction of various filtration elements provided in the solvent recovery or regeneration circuits after contamination of said elements.
