度の減少せねばならない。 So-called steam cleaning, in which articles are cleaned with organic solvent vapor, is carried out alone or in combination with other cleaning methods, such as immersion cleaning or spray cleaning using organic solvents. In addition, in steam cleaning, the organic solvent in the steam generation tank is evaporated and the resulting steam is used, so the organic solvent does not need to be purified and used, and is generally discharged from other processes, such as the above-mentioned immersion cleaning and spray cleaning processes. Organic solvents containing contaminants such as oil are often used. However, in order to effectively use the organic solvent in the steam generation tank as organic solvent vapor, increasing the concentration of contaminants in the steam generation tank will lead to an increase in the boiling point of the organic solvent.
Under certain heating conditions, the amount of evaporation of the organic solvent decreases, resulting in a problem that a large amount of cleaning time is required. Also, as the concentration of contaminants in the steam generation tank increases, the contaminants cause foaming, which must reduce the evaporation rate.

By evaporating the organic solvent containing pollutants in the steam generation tank while flowing in a fixed direction so as to create a concentration gradient of the pollutants, it is possible to increase the amount of pollutants while suppressing the decrease in the amount of steam generated and foaming in the steam generation tank.

発させることが好ましい。 The most important feature of the present invention is that the organic solvent containing pollutants is evaporated in a steam generation tank while flowing in a fixed direction so as to create a concentration gradient of the pollutants. As mentioned above, the organic solvent supplied to the steam generation tank does not need to be purified because the steam is used for cleaning, and it is not necessary that the organic solvent contains pollutants such as oil discharged from other processes. used. Further, contaminants are also contained in the organic solvent that condenses on the surface of the article and falls during steam cleaning. The present invention reduces the amount of steam generated, that is, the cleaning ability, by flowing the organic solvent containing the pollutants in a fixed direction so as to create a concentration gradient of the pollutants, and evaporating the entire evaporation surface of the flow. Contaminants contained in organic solvents can be concentrated to a high concentration while being prevented. Therefore, it has the advantage that the organic solvent supplied to the steam generation tank can be used for steam cleaning without waste. In the present invention, the method of evaporating the contaminant while flowing it in a fixed direction so as to create a concentration gradient is not particularly limited, and the method of evaporating the organic solvent while flowing it so that the organic solvents before and after the flow do not mix with each other is adopted without particular limitation. . For example, a steam generation tank is composed of multiple tanks, and the organic solvent is evaporated while flowing through each tank sequentially.
A method of creating a concentration gradient of pollutants in each tank,
A common method is to configure the steam generation tank with a long and narrow channel, and evaporate the organic solvent while flowing it through the channel, thereby continuously creating a concentration gradient of the contaminant. According to the above-described method, the contaminants contained in the organic solvent flowing in the steam generation tank are sequentially concentrated and reach the highest concentration at the end of the flow. In the present invention, organic solvent is removed from the end of the stream. The concentration of contaminants in the organic solvent taken out from the steam generation tank varies depending on the type of organic solvent and the type of contaminant as described below, but generally the concentration of the organic solvent in the steam generation tank is 50% by volume or more. It is preferable to evaporate it.
