Abstract

PURPOSE:To prevent the outflow of evaporating solvent gas to the atmosphere by injecting a noncombustible gas having specific gravity to the cooling phase of the evaporating solvent gas in a cleaning device using a chlorine or fluorine org. solvent. CONSTITUTION:At the time of heating a cleaning soln. 2, which is a chlorine or fluorine rog. soln., put into a cleaning vessel 1 and cleaning the object to be cleaned by the heated liquid phase 3 and evaporating solvent gas phase 4, a noncombustible gas such as carbon dioxide or nitrogen gas which is heavier in specific gravity than air and is lighter than the evaporating gas of the solvent is injected into the cooling phase 7 in the upper part of the vessel 1. Then, the noncombustible gas shuts off the opening 9 of the vessel 1, thereby preventing the outflow of the evaporating solvent gas into the atmosphere.
