Description: BACKGROUND OF THE INVENTION (Field of Industrial Application) The present invention relates to a solvent recovery device of a dry cleaning device capable of preventing the solvent from being released from a dry gas cleaner and reducing costs.

(Prior Art) A conventional dry cleaning apparatus is configured as shown in FIG. 5, and a cleaning step includes a cleaning step, a liquid removing step, a drying step, and a deodorizing step in this order.

First, in the cleaning step, the object to be washed 01 is perchlorethylene,
1.1.1-Soak in highly volatile solvents such as trichloroethane, R11 and R113 to remove dirt. Further, in the liquid removing step, the washing drum 02 is rotated at a high speed to centrifuge the solvent. In the drying process, the air inside the cleaning device is circulated by a fan.
With 03, the water is passed through the water-cooled cooler 04 and the heater 05 and circulated into the washing drum 02.

That is, the temperature of the air is raised by the heater 05 to evaporate the solvent adhering to the article 01 to be washed, and the evaporated solvent gas is guided to the water-cooled cooler 04 to be cooled to about 32 to 35 ° C. Thus, the solvent gas is condensed and liquefied and recovered. However, the solvent gas contained in the air is better removed as the cooling temperature is lower in relation to the saturation concentration. Therefore, for example, when the solvent is perchlorethylene, the concentration of the solvent contained in the air is reduced at a cooling temperature of about 35 ° C.
250 g / m 2 can not be less, Hiaraibutsu 0 in this state
Strong odor remains in 1. Therefore, in the deodorization step, in order to remove the odor and cool the object to be washed 01, the fresh air damper 06 is opened to take in the outside air, and the outside air is brought into contact with the object to be washed 01 to dilute the solvent gas concentration. The air is discharged outside from the exhaust damper 07.

Although this exhaust gas was diluted, it was initially tens of thousands of ppm.
Solvent gas is discharged through the duct 08 through a duct 08 for the purpose of countermeasures and resource saving by solvent recovery. Activated carbon tank 010 provided adsorbs only clean air to the atmosphere. The solvent adsorption tank 09
When the activated carbon reaches saturation with the adsorbed solvent gas, the activated carbon is sprayed with steam from a steam pipe 011 to evaporate the solvent and perform so-called desorption. The evaporated solvent gas is guided to the water-cooled condenser 012 to be condensed and liquefied, and is separated and recovered by the water separator 013 into a recovered solvent and water. After the desorption step, the drying fan 014 is operated to start a drying step for drying the activated carbon layer 010, and the activated carbon layer 010 is regenerated to prepare for the next adsorption step.

(Problem to be Solved by the Invention) The conventional activated carbon adsorption solvent recovery apparatus shown in FIG. 5 has an original blower, a condenser, and a water separator in order to regenerate activated carbon during solvent desorption and drying. Therefore, there was a problem that the cost was high. Also, in the deodorization process, even after passing through activated carbon, there is a problem that the solvent gas concentration is released to the outside without being reduced to zero, and after the solvent absorbed in the activated carbon is blown out by blowing steam,
The activated carbon is dried by blowing warm air. However, the regulated value for the initial exhaust air (discharged out of the machine as it is) at this time
Solvent gas with a concentration of 50 PPM or more is discharged, but if the exhaust port is open to the atmosphere, discharge of this high concentration gas is inevitable.

(Action) During recovery (desorption step) of the solvent from the activated carbon, the vapor and the expelled solvent gas are led to the cooling device of the dry cleaner body to condense, and the liquid generated by the condensation is sent to the water separator of the dry cleaner body. . Similarly, the wet air coming out of the activated carbon in the activated carbon drying process is sent to the dry cleaner main body and dried through the dry cleaner's blower, cooling device, water separator, and air heater. Is again used for activated carbon drying. Furthermore, in the deodorization process, the air from which the solvent gas has been removed with activated carbon is directly sent to the treatment tank of the dry cleaner and used repeatedly in a closed loop for deodorization, so that even a small amount of solvent gas that could not be removed with activated carbon is released outside the machine. No more. Also, in the activated carbon drying step, the medium air is circulated in a closed loop in which the adsorber and the dry cleaner are tight, so that the solvent gas having a high concentration generated in the early stage of drying can be prevented from being discharged outside the apparatus.

(Effect of the Invention) As described in detail above, the present invention is configured, so that a condenser (cooling device), a blower, and a water separator are provided as compared with a case where the activated carbon recovering machine has a collecting function and a drying function independently. Since the function of the dry cleaner main body can be shared, the cost can be reduced. In the deodorization (adsorption) process, the flow of the solvent gas and the air can be processed in a closed loop, so that there is an advantage that the solvent gas does not come out to the outside air. Pollution problems caused by the initial breakthrough of high-concentration gas can be prevented. Further, the discharge of water vapor in the first half of drying, which has occurred in the conventional recovery machine, is eliminated, and a small amount of solvent gas contained in the water vapor can be recovered. Further, since the processing is performed in a closed loop, a large-diameter exhaust duct is not required. In other words, the functions required for solvent recovery share parts of the dry cleaner body, so that costs can be reduced, and drying after desorption is performed in a closed circuit. Since the deodorizing step is also performed in a closed circuit, the solvent gas is not released to the outside.
