Therefore, the air drawn into the drying ventilation passage (14) from the washing tub (18) by the blower (17) is transferred to the condenser (18).
), the condensed solvent is collected in the collected liquid collecting tank (25), and when the solenoid valve (26) is opened after the drying process is completed, it is transferred to the water separator ( 21>, and is further collected in the solvent tank 2>.On the other hand, the air that has passed through the condenser (18>) flows into the heater (19).
). The heat medium passage (19') of this heater (19)
) is flowing the high temperature solvent vapor evaporated from the distiller (8) as described above, so this heater (19) is at a high temperature. Therefore, the air is heated when passing through the heater (19), becomes hot air, and flows into the washing tub 1).
The solvent is blown out to evaporate the solvent from the clothes in this washing tub, drying the clothes. On the other hand, the heating medium passage (19') of the heater
The solvent vapor flowing through the heater (19) radiates heat and condenses, and then flows into the water separator (21).The solvent that has entered the water separator (21) is
2>, and after water is separated, the solvent is collected in a solvent tank (2). This drying process continues until the distillation is complete. That is, when the distillation is completed and the solvent in the distillation chamber (10) disappears, the pressure in the heating chamber (11>) increases rapidly, which is detected by the pressure switch (13) and the drying process ends.

When drying is completed in this way, the deodorizing process begins. In the deodorizing process, the intake valve (27) and the exhaust valve j1' (28) are switched to the solid line positions shown in the figure to open the intake port (29) and the exhaust port (30), and the washing F! Fresh air is taken into the washing tub (1', 1) and then exhausted from the negative port (30 in).As a result, even after the drying process, the solvent vapor that was filled in the washing tub (1', ) can be completely discharged.

However, as is clear from the characteristic diagrams in sections 4 (a) and (b), the solvent is dissolved in water, so the discharged water contains the solvent. In addition, unless the solvent becomes large droplets by condensation, it cannot be completely separated by the difference in specific gravity, and is completely dispersed in the water layer in a fine colloidal state, increasing the solvent content in the υ1 water to the solubility group - H. Furthermore, if the solvent does not form into large droplets, the difference in surface tension acts more strongly than the difference in specific gravity, causing the solvent to rise above the surface of the water layer, and sometimes exit from the discharge pipe (38) as it is. In this way, the discharged water is mixed into groundwater and the like, but since chlorinated solvents are carcinogenic substances, it has been desired to completely recover the solvents in the discharged water.

In this way, in this embodiment, the separated water is sequentially transferred to the separating means depending on the water head difference, so a special pump or the like is not required. In addition, if the secondary discharge water from the water separator (40) is directly transferred to the adsorption device (61), the amount of activated carbon (63) may be increased, and the activated carbon (63) may not be replaced frequently (
Since there is no possibility of the two being in contact with each other, the operating cost of the separator increases significantly. However, in this embodiment, since the aeration device (48) is provided as a secondary separation means, the life of the activation device (63) can be extended, and costs can be reduced.

(f) Effects of the Invention According to the present invention, solvent vapor is released by an aeration device before adsorbing and removing the solvent from separated water, which makes it possible to prolong the life of activated carbon used in the adsorber and improve economic efficiency. A highly effective dry cleaner can be provided.
