(1) is the main cleaning means, in which the non-aqueous flammable solvent (3) stored in the solvent storage tank (2) is supplied with a non-aqueous flammable solvent through a pump (4) and a filter (5). Solvent (3)
A solvent nozzle (6) for spraying is connected, and this solvent nozzle (6) is formed on the inner peripheral surface of a main cleaning tank (8) that performs the main cleaning of the object (7) to be cleaned. Also,
The non-aqueous flammable solvent (3) may be a terpene solvent, a hydrocarbon solvent, or a silicone solvent, and may be any non-aqueous solvent depending on the purpose of cleaning. A water-soluble flammable solvent (3) can be used. Also,
Injecting these non-aqueous flammable solvents (3) increases the contact area with the air and increases the risk of ignition, so the inside of the main cleaning tank (8) is completely fluorinated, which is nonflammable. Filling with liquid vapor or filling with fully fluorinated liquid in liquid form ensures that the risk of ignition is eliminated. Furthermore, non-aqueous flammable solvents (3)
By mixing water with water and spraying it on the object to be cleaned (7),
It may also be used to clean the object to be cleaned (7).

、引火の危険性を生じるようなことがない。As a result of the above injection of water (11), the non-aqueous flammable solvent (3) mixed with water (11) will not dissolve in water (11), so the difference in specific gravity will occur over time. Separated from water (11), both water (11) and non-aqueous flammable solvent (3) can be reused as they are or through a water separator, reducing problems such as pollution caused by wastewater. It never occurs. In addition, water (11) is added to the object to be cleaned (7).
Since this method physically removes the non-aqueous flammable solvent (3) by injecting it into Air containing a large amount of non-aqueous flammable solvent (3) is not exhausted outdoors, the amount of solvent consumed is increased, and there is no risk of air pollution or ignition.

After the removal of step 3), the object to be cleaned (7) with water (11) attached to its surface can be dried using any drying means (17). This drying of the object to be cleaned (7) is to dry the adhering water (11) and not to dry the non-aqueous flammable solvent (3), so there is a risk of ignition. There is no risk of air pollution. Therefore,
Any drying means can be used, but the object to be cleaned (7
) A plurality of air nozzles (21) are arranged around the inner periphery of a drying tank (20) provided with a storage space (18) for drying by blowing off water (11) with high-pressure air. Another drying means (17) is one in which a heated drying atmosphere capable of drying the water (11) adhering to the object to be cleaned (7) is created in the storage space (18) using hot air, superheated steam, etc. Also good.

発明の効果
本発明は上述のごとく構成したものであるから、被洗浄
物は、非水溶系の可燃性溶剤に接触して洗浄作業を行な
い、水系の洗浄を行う場合に比較して、被洗浄物の洗浄
を著しく早（行うことができ、作業効率を向上できる。Effects of the Invention Since the present invention is configured as described above, the object to be cleaned is cleaned by contacting with a non-aqueous flammable solvent, and the cleaning work is performed by contacting the object with a non-aqueous flammable solvent. You can wash things extremely quickly and improve work efficiency.
また、被洗浄物に付着した非水溶系の可燃性溶剤は、水
の噴射によって、その殆どが水の物理的圧力により除去
され、引火の危険がないとともに水と混合した非水溶系
の可燃性溶剤は、水に溶解することがないから、時間の
経過により比重差で水と分離し、水も非水溶系の可燃性
溶剤もそのまま再利用することが可能となり、排水によ
る公害等の問題を生じることがない。In addition, most of the non-aqueous flammable solvents adhering to the object to be cleaned are removed by the physical pressure of the water by water injection, and there is no risk of ignition, and non-aqueous flammable solvents mixed with water are removed. Since solvents do not dissolve in water, they separate from water over time due to the difference in specific gravity, making it possible to reuse both water and non-aqueous flammable solvents as they are, eliminating problems such as pollution caused by wastewater. It never occurs.
また、水を被洗浄物に噴射して非水溶系の可燃性溶剤を
物理的に除去するものであるから、高圧の空気を噴射し
て非水溶系の可燃性溶剤を除去する従来方法のごとく、
非水溶系の可燃性溶剤を多く含んだ空気を、屋外にその
まま排気したり、溶剤の消費量を多くしたり、大気汚染
、引火の危険性を生じるようなことがない。In addition, since water is injected onto the object to be cleaned to physically remove non-aqueous flammable solvents, it is similar to the conventional method of injecting high-pressure air to remove non-aqueous flammable solvents. ,
Air containing a large amount of non-aqueous flammable solvents is not exhausted outdoors, the consumption of solvents is increased, and the risk of air pollution or ignition is not caused.
また被洗浄物の乾燥は、いずれの乾燥手段を用いる場合
であっても、水を乾燥するものであるから引火の危険、
大気汚染等は生じることがなく、安全な洗浄作業を可能
とするものである。In addition, no matter which drying method is used to dry the item to be cleaned, there is a risk of ignition because it dries water.
This does not cause air pollution or the like and enables safe cleaning work.
