- cleaning equipment that uses cleaning agents employs a mechanism that integrates various cleaning processes such as immersion cleaning, vaporization cleaning, and shadow cleaning to improve the cleaning efficiency. It is assumed that a single type of cleaning agent will be used. This is because if multiple cleaning agents are used in a series of washing steps, it becomes difficult to collect and reuse the cleaning agents. This is a major obstacle, for example, when trying to achieve a cleaning effect that cannot be achieved by itself by using multiple cleaning agents.
- an organic solvent-based cleaning agent such as a fluorocarbon-based solvent has a serious drawback of causing environmental destruction.

- a monovalent substituted hydrocarbon group such as a trifluoromethyl group, etc., and a methyl group is most preferable in terms of stability of the system and maintenance of volatility.
- low molecular weight polyorganosiloxane those having a cyclic structure are preferable, and octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and a mixture thereof are more preferable.
- the above-mentioned low molecular weight polyorganosiloxane can satisfy the following formula (A) or (B) by appropriately selecting the molecular structure so that the specific gravity Ddg of the detergent can be satisfied.
- Ddg indicates the specific gravity of the base detergent
- Wdg indicates the specific gravity of water
- Odg indicates the specific gravity of the target oil-based soil.
- satisfying the expression (B) makes it possible to separate water and oil-based dirt, thereby facilitating cleaning and drainage treatment of the cleaning agent.
- Isoparafi in as the Isoparafi emissions based detergent as described above include those carbon atoms consists essentially of volatile Isoparafi emissions in the range of 1 to 30, which in particular mainly fraction c 3 ⁇ c 15 Is preferred from the viewpoint of cleaning performance.
- Such an isobaraffin-based detergent is used as one or a mixture of two or more of the above volatile isoparaffins. These isoparaffins are volatile, harmless and odorless, and exhibit the same effects as the low molecular weight polyorganosiloxane described above ( It should be noted that the organic gay detergent and the isoparaffinic detergent listed as the above basic detergents can, of course, be used alone, or that they can be mixed and used as a basic detergent. It is possible. For example, blending an isoparaffinic detergent with an organic gay detergent has the effect of significantly lowering the freezing point.

After complete separation of oil and water, the oil and water are each removed with a detergent, but there is a possibility that a small amount of detergent may be mixed into the removed oil and water. However, detergents mixed in oils and fats easily flint during incineration of waste oil, and there is no problem in incineration. Also, cleaning agents mixed in water will not cause any problem because they can be easily separated from water by a filter distilling device.
- the cleaning agent can be used efficiently and effectively, and a plurality of cleaning agents can be used. This is a significant step down in the use of cleaning agents and contributes to a significant reduction in running costs.
- the cleaning device of the present invention as a pre-process of IPA steam drying, water is prevented from being mixed into the regenerated IPA, and since the difference in boiling point between IPA and the draining agent is large, Steam cleaning of IPA only becomes possible. Since water and IPA have close boiling points, it is difficult to remove water, which causes a watermark and the like.
