Claims (17)

Steam or steam and nitrogen or steam and carbon dioxide are supplied to the inlet and outlet of the object to be cleaned and the communication between the cleaning atmosphere and the outside air is carried out by steam or steam and nitrogen or steam and carbon dioxide. Between the inlet and the outlet, a washing chamber to use a flammable solvent having a lower boiling point than water and a distillation to separate water and the flammable solvent are installed between the inlet and the outlet to connect the condenser's condenser to the washing chamber and connect the washing chamber. The condensate can be refluxed by a diesel oil and the contaminant removed from the object to be washed is discharged out of the system together with the condensate separated from the combustible solvent in the distillation. It is necessary to block steam or steam and nitrogen or steam and carbon dioxide gas at the inlet and outlet of the object to be cleaned and to separate the cleaning chamber and water and the flammable solvent which will use a flammable solvent having a lower boiling point than water at this outlet. The condenser is connected and the condenser of the distiller is connected to the rinsing chamber, and the condensate can be refluxed in the distant through the rinsing chamber, and the contaminant removed from the object to be washed together with the condensed water lost from the combustible solvent in the distiller. Washing apparatus characterized in that discharged to the outside of the system. The washing apparatus according to claim 1 or 2, wherein the steam uses superheated steam. The cleaning apparatus according to claim 1 or 2, wherein the cleaning chamber is formed with a liquid cleaning tank containing a flammable solvent for cleaning the object to be cleaned. The cleaning apparatus according to claim 1 or 2, wherein the cleaning chamber is provided with a shaw nozzle in which the object to be washed is washed. The cleaning apparatus according to claim 1 or 2, wherein a liquid cleaning tank for immersing and cleaning the object to be cleaned and a shawa nozzle for shawa washing the object to be cleaned are formed in the cleaning chamber. The washing apparatus according to claim 1 or 2, wherein a steam washing zone is formed in the washing chamber, a vapor of the distillation machine is introduced into the condenser via the steam washing zone, and the washing target is steam-cleaned. The cleaning apparatus according to claim 1, wherein a dry zone is formed between the cleaning chamber and the discharge port. The cleaning apparatus according to claim 2, wherein a dry zone of the object to be cleaned is formed between the cleaning chamber and the delivery openings. The cleaning apparatus according to claim 8 or 9, wherein the drying zone is introduced with a superheat steam to serve as a drying heat source for the object to be cleaned. The cleaning apparatus according to claim 8 or 9, wherein the drying zone forms a heater using steam, hot water, heating oil, electric heater, and the like as a drying heat source of the object to be cleaned. The cleaning apparatus according to claim 8 or 9, wherein the drying zone connects a blower so as not to communicate with outside air and heats a gas to circulate the drying zone in the blower. The washing apparatus according to claim 1 or 2, wherein the distillator introduces stripping steam to concentrate the combustible solvent and separate the water. The washing apparatus according to claim 1 or 2, wherein the distillator is provided with a reboiler and uses it as a heat source to concentrate the flammable solvent and separate the water. 11. The cleaning apparatus according to claim 1, 2, 8, 9 or 10, wherein the distillator introduces steam used as a dry heat source in the drying zone to concentrate the flammable solvent and separate the water. The flammable solvent according to claim 1 or 2 is used alone or in plural kinds of petroleum compounds such as methanol, ethanol, alcohols of isopropyl alcohols, ketone-based benzenes such as acetone, methyl ethyl ketone, etc., having a lower boiling point than water. Washing apparatus, characterized in that. The washing apparatus according to claim 1 or 2, wherein the operation of the still is carried out intermittently. ※ Note: The disclosure is based on the initial application.
