以下にはならない。Next, a conventional solvent recovery device will be explained with reference to FIGS. 3 and 4. The solvent gas evaporated from the clothing 2 during the drying process is cooled by the air cooler 17 and condensed and recovered. Since the air cooler 17 is usually water-cooled and uses well water,
Cool the solvent gas to about 32-35°C. There, the solvent gas is condensed and recovered, but the concentration of the solvent gas contained in the air does not fall below the saturation concentration determined by the temperature and pressure at that time.

At around 5℃, the concentration of solvent contained in the air is reduced to 250 g.

。Therefore, in the deodorizing process of item 0, in order to remove this residual odor, the processing drum 11 is rotated, the damper 25 is opened to take in a large amount of outside air, and this is brought into contact with the clothing 2 to dilute the solvent gas concentration. , is exhausted from the damper 26 to the outside of the machine.

放出している。(Problems to be Solved by the Invention) However, although the exhaust gas from the conventional device has been diluted, it initially contains solvent gas that reaches up to 100 ppm, resulting in the problem of air pollution. When Freon-11 or Freon-113 is used and released into the atmosphere, depletion of the ozone layer surrounding the earth has become a problem, and there is an international movement to reduce production. Therefore, in the conventional device shown in FIG. 3, the diluted solvent gas discharged from the damper 26 is guided through a duct 37 to the solvent recovery device 30 shown in FIG. By contacting and adsorbing the solvent gas with the activated carbon layer 32 in the solvent recovery device 30, the solvent gas is released into the atmosphere as clean air.

すると、乾燥ファン３６により新鮮な空気を送り込み、
活性炭層３２を乾燥、再生して次の吸着工程に備える。When the solvent gas recovery capacity of the activated carbon layer 32 reaches saturation, high-pressure steam is blown onto the activated carbon from the steam pipe 33 to evaporate the solvent in the activated carbon, so-called desorption.The evaporated solvent gas is transferred to a water-cooled condenser 34. The water is condensed and liquefied, separated into water and solvent by the water separator 35, and the solvent is recovered into the clean tank 24. When the desorption process is completed, a drying fan 36 blows in fresh air.
The activated carbon layer 32 is dried and regenerated in preparation for the next adsorption step.

た。However, as mentioned above, conventional solvent recovery equipment takes in a large amount of outside air, dilutes the solvent gas concentration inside the machine (processing tank and recovery), and exhausts the solvent gas outside the machine while rotating the processing drum 11. Since it is assumed that the solvent gas will be treated, the amount of solvent gas to be processed will inevitably increase, and the solvent recovery equipment 3
0 becomes large in size, and running costs such as device cost, installation area, and recovery energy become expensive, and these are major factors that prevent the installation of the solvent recovery device 30.

の課題を解決しようとするものである。As mentioned above, in the conventional solvent recovery device, as mentioned above, a large amount of outside air is taken in to rotate the processing drum and the solvent gas inside the machine is recovered while being diluted, resulting in a large size of the device. Although there has been a problem, the present invention attempts to solve this problem.

At the same time as the replacement, the solvent gas is supplied to the solvent recovery device one to several times, and this serves as a means and function for solving the problem.

４を配設してなるものである。Next, the small solvent recovery device 30a shown in FIG. 2 will be explained. The device 30a has an activated carbon layer 42 in the center with a capacity of about 1710 mm compared to the conventional one, and is used for inhaling solvent gas and regenerating and drying activated carbon. A fan 46 and pulps 51, 52, 53 for circuit switching are provided, and a steam pipe 43 for desorption including a steam valve 54 for desorption of the solvent adsorbed on activated carbon, and a steam pipe 43 for condensation and recovery of the evaporated solvent. water-cooled condenser 4

出する。First, when the dry cleaning apparatus completes the predetermined cleaning and drying steps as in the conventional manner, the processing drum 11 is stopped, and then the damper 26a or 26b, which is an upper opening for taking in outside air, is opened.
is opened as shown by the broken line, and the solvent gas inside the machine is transferred to the damper 26a or 2 by the fan 46 through the pulp 50a or 50b.
A small solvent recovery device 30 is used to remove the solvent gas inside the machine in the direction of the arrow 20a with a small air volume that does not mix with the outside air from 6b.
The solvent gas is fed into the activated carbon layer 42 in a, the activated carbon adsorbs the solvent gas, and it is released into the atmosphere as clean air through the pulp 52.

次にパルプ５３、ファン４６、パルプ５２から成る経路

（脱臭工程）に備える。Next, outside air is introduced through a path consisting of the pulp 53, fan 46, and pulp 52 to dry the activated carbon layer 42 in preparation for the next adsorption step (deodorizing step).

しても、同様の効果は得られる。In addition, according to this method, as mentioned above, the amount of air required to discharge the solvent gas inside the machine is approximately 1,710 liters compared to the amount of air treated by the conventional dilution deodorization method, so the activated carbon layer 42 can be made smaller. The capacity can be increased, the attached devices such as the water cooling condenser 44 and the fan 46 can also be made smaller, and the entire solvent recovery device can be made more compact. Of course, the same effect can be obtained even if the small-sized solvent recovery device 30a of the embodiment of the present invention is installed separately as in the conventional method.

リエーションが考えられることは云うまでもない。Furthermore, in the method of the present invention, it is possible that trace amounts of solvent components remain in the clothing. However, the recovery method is to rotate the stopped processing drum again, diffuse the residual solvent components in the clothing into the processing tank, and then stop the processing drum again and perform the aforementioned deodorization. . In this example, a device using activated carbon was used as the solvent recovery device, but a device using other adsorbents (e.g. zeolite), a condensation recovery method using a refrigeration device, or a device using the same type of solvent or Needless to say, various variations are possible, such as an absorption type in which the absorbent is brought into contact with oil or the like and absorbed, and a combination of these types.

The amount of gas required to recover a certain amount of solvent in the processing tank is reduced, and the solvent recovery equipment can be made much smaller than before, resulting in the prevention of air pollution and ozone layer depletion, and resource conservation through solvent recovery. Therefore, a space-saving, low-cost solvent recovery device can be obtained.

特徴とするドライクリーニング装置における溶剤回収方
法。This is a method of exhausting air while the rotation of the processing drum is stopped during the deodorizing process, in which outside air is taken in through an upper opening provided at the top of the processing tank or the top of the recovery air duct, and a lower opening provided at the bottom of the processing tank or button trap section. The solvent gas in the processing tank is slowly evacuated using the exhaust means connected to the solvent recovery device while the processing drum is stopped, so as not to stir the solvent gas in the processing tank, and at the same time the solvent gas in the processing tank is replaced. A method for recovering a solvent in a dry cleaning device, the method comprising supplying the solvent to the recovery device once or several times.
