九。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning method for cleaning an object to be cleaned in a trichlorethylene solution. Cleaning is being done. In the conventional cleaning method for this building, for example, as shown in FIG. 5 is immersed and cleaning is performed while viewing ultrasonic waves using an ultrasonic vibrator 6. However, with this method, the highly volatile trichlorethylene evaporates from the surface into the atmosphere during cleaning, and after cleaning, it is necessary to remove the trichlorethylene remaining on the surface or inside of the initially precipitated material. When drying washed items, trichlorethylene escapes into the atmosphere and contaminates the outside air.
本発明の目的は、トリクロルエチレンが大気を汚染する
のを防止した洗浄方法を提供することにある。An object of the present invention is to provide a cleaning method that prevents trichlorethylene from polluting the atmosphere.

換することを特徴とじ九ものである。In the cleaning method of the present invention, two layers, a water layer and a trichlorethylene layer, are formed in a cleaning tank, and the object to be cleaned is first cleaned in the trichlorethylene layer, and then in the water layer. It is characterized by replacing trichlorethylene remaining on the surface or inside with water.

の２層により構成した点である。The cleaning method of the present invention will be explained below with reference to the drawings. Figure 92 shows a schematic configuration of an apparatus for carrying out the cleaning method of the present invention. The difference from FIG. 1 is that the cleaning liquid put into the cleaning tank 4 is composed of two layers: 60 layers of trichlorethylene and 1' layer of water.

とを置換するため、水１′の中で洗浄を行う。In carrying out the method of the present invention, first, a predetermined amount of trichlorethylene 6 is poured into the cleaning tank 4. Next, add approximately the same amount of water 1' as trichlorethylene. The ratio of trichlorethylene is about 14, which is higher than that of water, and trichlorethylene is mostly present in water. After forming a trichlorethylene layer and a water layer in the cleaning tank 4 in this way, cleaning is first performed in trichlorethylene 6, and then the trichlorethylene and water remaining on the surface or inside of the object 50 to be cleaned are removed. Washing is carried out in water 1' to replace the .
その後、必要であれば、乾燥話中で水分を乾燥除去する
。Thereafter, if necessary, the water is removed by drying in a drying process.
上記のように、トリクロルエチレンの上部に水の層を形

内部に残留しているトリクロルエチレンを完全に水と置
換できるため、乾燥中にトリクロルエチレンが大気中に
逸散すること４なく、大気汚染を防止できる。As described above, by forming a layer of water on top of trichlorethylene, the surface of trichlorethylene is completely sealed, thereby preventing trichlorethylene from volatilizing into the atmosphere during cleaning. In addition, since trichlorethylene remaining on the surfaces and inside of the object to be cleaned can be completely replaced with water before drying, trichlorethylene does not escape into the atmosphere during drying, thereby preventing air pollution. .

用いないでトリクロルエチレン中での洗浄を行う場合に
も同様に本発明を適用することができる。In addition, in order to improve the cleaning efficiency and the efficiency of replacing trichlorethylene remaining on the surface and inside of the object to be cleaned with water, it is also possible to heat the cleaning liquid. The present invention can be similarly applied to cleaning in trichlorethylene without using ultrasonic waves.
以上説明したように、本発明に係る洗浄方法によると、
大気中へ有害なトリクロルエチレンが逸散するのを防止

る利点がある。As explained above, according to the cleaning method according to the present invention,
This has the advantage of being able to prevent harmful trichlorethylene from escaping into the atmosphere, thereby preventing air pollution from occurring.
