Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a dry cleaner distiller using an organic solvent such as perchlorethylene, 1.1.1 trichloroethane, and R113.

(Prior Art) A conventional dry cleaning process will be outlined with reference to FIGS. 3 and 4. First, put the clothes 2 through the door 1 and then the door 1
When is closed and the operation is started, the steps generally proceed in the following order.

． The solvent 4 is pumped from the solvent tank 3 through the valve 5 by the pump 6, and the required amount of the solvent 4 is sent to the processing tank 10 through the path including the valve 7 and the filter 8 or the path including the valve 9.

． Slowly turn the processing drum 11 to add the solvent 4 to the processing tank 10,
The garment 2 is washed by circulating it through a circuit consisting of the button trap 12, valve 13, pump 6, valve 7, filter 8 or valve 9.

． The treatment tank 10, the button trap 12, the valve 13, the pump 6, the valve 14, the liquid supply pipe 50, and the distiller 15 are used to drain liquid, and then the treatment drum 11 rotates at high speed to centrifuge the solvent 4 in the clothing 2. Separate and drain as well.

． Repeat the process of item and item.

． Processing tank 10, button trap 12, valve 13, valve 5
The solvent 4 is centrifugally separated and drained through the route.

． The processing drum 11 is slowly rotated again, and a recovery air duct 19 including a fan 16, an air cooler 17, and an air heater 18 is provided.
Air is circulated between the processing tank 10 and the treatment tank 10 in the direction of the arrow 20 to dry the garment 2. The solvent gas evaporated from the clothes 2 is condensed by the air cooler 17, enters the water separator 22 via the recovery route 21,
Enter the clean tank 24 through the solvent pipe 23.

． When the drying is completed, the dampers 25 and 26 open as indicated by broken lines, fresh air is taken in from the damper 25, uncondensed solvent gas that cannot be recovered by the air cooler 17 is exhausted, and the solvent odor in the clothing 2 is deodorized.

． The solvent 4 that has entered the distiller 15 in the step of the above item evaporates and is condensed and collected by the condenser 27. The water separator 22 and the solvent pipe 23
Through the partition plate with overflow 28 to the solvent tank 3. The water separated by the water separator 22 is discharged to the outside of the system by the water pipe 29.

(Problems to be solved by the invention) In the steps and in the above steps, as the distillation of the used solvent 30 progresses, the fiber scraps 31 separated from the clothing 2 on the inner surface of the side wall of the distiller 15 near the boiling interface 31 are washed. However, there is a drawback that HCl produced from Cl in the solvent component is concentrated at that portion and adheres and is fixed, and if left as it is, the side wall of the still is corroded and the still is damaged.

In the present invention, by providing the liquid jetting means, the fiber scraps and the like separated from the clothes during cleaning are fixedly deposited on the inner surface of the side wall of the still that recycles the used solvent in the conventional dry cleaner, which causes distillation. The present invention aims to solve the above-mentioned conventional problem that the vessel is corroded and damaged.

(Means for Solving the Problems) Therefore, the present invention relates to a dry cleaner distiller that uses an organic solvent and distills and regenerates the used solvent. A means for ejecting the liquid to the inner surface of the side wall of the still is provided so as to constantly clean the side wall surface, and this is a means for solving the problem.

(Function) By spraying the used solvent for distillation regeneration directly on the inner surface of the side wall of the still, it is possible to increase the amount of sticking of the fiber scraps, etc., that have come off from the clothing during washing, to the inner surface of the side wall of the still, and to fix it. Can be prevented.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.
FIG. 2 and FIG. 2 respectively show the first and second embodiments of the present invention, in which the spray nozzle 36 or 46, which is a fixed or movable (rotating) liquid spray means, is provided in the upper layer of the still 35. Is installed in the gas layer portion of the pump, and a drain pipe from the pump 6 is connected to the nozzles 36 and 46. In addition, 32 is a heating jacket, 30
Is the used solvent.

Next, the operation will be described. The pump 6 for the used solvent 30 containing the dirt and the fiber scraps 31 that have been separated from the clothing 2 after the cleaning is completed.
From the processing tank 10 to the button trap 12, valves 13,14,
It is introduced into the inside of the distiller 35 through the liquid supply pipe 50, and the solvent is vigorously and uniformly sprayed from the spray nozzle 36 or 46, which is the liquid spray means, toward the inner surface of the side wall of the distiller 35 over the entire circumferential direction. Therefore, in the conventional method, it is possible to wash away the fiber scraps 31 and the like remaining on the inner surface of the side wall of the distiller 35 to eliminate the adhered accumulation.

(Effect of the Invention) Since the present invention is configured as described in detail above,
It is possible to prevent the sticking due to the residual adhesion of the fiber scraps or the like, which has been concentrated on a part of the inner surface of the side wall of the still, as in the conventional case, and prevent the corrosion accident of the still caused by the sticking.
