成させるにいたった。When the organic solvent leaks from the cleaning chamber, outside air is introduced into the cleaning chamber, and the vapor pressure of the organic solvent in the cleaning chamber decreases. Further, the evaporation of the organic solvent is further promoted, and the circulation of the leakage is caused. Therefore, by completely shutting off the space between the cleaning chamber and the outside air and substantially stopping the introduction of air into the cleaning chamber,
It is expected that the concentration of organic solvent vapor in the cleaning chamber will gradually increase and the amount of organic solvent vapor generated per hour will gradually decrease.If the concentration approaches the saturation concentration, the amount of organic solvent vapor generated will be substantially zero. Is also expected. Therefore, the present inventors have succeeded in achieving the object of the present invention by installing a liquid seal structure at the entrance and exit of the cleaning chamber for the purpose of completely shutting off the cleaning chamber from the outside air.

In particular, the following can be mentioned as specific examples of liquid storage tanks that can be suitably used in the present invention. For example, as shown in FIG. 1, a liquid storage tank 101 in which openings 103 and 103 'for passing an object to be cleaned 102 are provided on the outer and inner walls of the cleaning chamber can be exemplified. When the object to be cleaned is carried into the cleaning chamber, the object to be cleaned 102 includes the opening 103 outside the cleaning chamber provided in the liquid storage tank, the liquid 104 in the liquid storage tank, and the cleaning chamber inside the liquid storage tank. Are sequentially carried through the opening 103 '. Further, when the object to be cleaned is carried out of the cleaning chamber, the object to be cleaned is an opening on the cleaning chamber side provided in the liquid storage tank,
The liquid is sequentially passed through the liquid in the liquid storage tank and the opening of the liquid storage tank outside the cleaning chamber, and is carried out.

Good. For example, when the object to be cleaned is a strip, the shape of the opening may be a slit, and when the object to be cleaned is a wire, the shape of the opening may be a slit. Possible holes may be used. Also,
The size of the opening must be sufficiently large so as not to hinder the passage of the object to be cleaned, but if it is too large, the leakage of the liquid from the opening is too large, so that the capacity of the liquid storage tank is increased. Alternatively, the pump must be capable of delivering an amount of liquid that exceeds the amount of leakage, which is impractical. Therefore, it is usually preferable that the size of the opening is such that a gap of 10 mm or less is formed above and below the object to be cleaned and 50 mm or less on the left and right sides when the object to be cleaned is passing through.

Because, for example, the object to be cleaned which have passed through the liquid in the storage tank 27 as shown in FIG. 4 through between a pair of squeeze rolls 5, with the necessity
Steam blowing nozzle or cold air blow 2 depending on
By spraying with 8, the liquid accompanying the object to be cleaned is collected in a liquid receiver provided below the liquid storage tank .
Although the method of this is not particularly necessary for passing through the cleaning chamber inlet of the liquid storage tank to be washed, the liquid that accompanies the object to be cleaned which have passed through the liquid reservoir of the washing chamber outlet for directly connected to Ross This is effective as a method for recovering such an object to be cleaned. In particular, in the case where the cleaning chamber is a drying chamber that employs a method such as hot air drying at the outlet side of the cleaning chamber, the above-described liquid removal by a squeezing roll, cold air blow, or the like is a very effective method. In this case, or it hits the liquid reservoir to the hot air of the drying chamber directly, in order to avoid evaporation loss of liquid due to heat transfer, it is preferable to provide a partition wall between the drying chambers.

空気よりも重く、洗浄室下部からの有機溶剤蒸気の漏洩
を防止するため、洗浄室の上部であることが好ましい。In the present invention, since the inlet and outlet of the object to be cleaned in the cleaning chamber are kept airtight by the liquid storage tank as described above, a difference may occur between the inside of the cleaning chamber and the outside air pressure. In this case, depending on the structure of the liquid storage tank, there is a difference between the liquid levels on the inside and outside of the cleaning chamber, or the liquid flows out to the side with a lower pressure. In order to prevent this, it is preferable to connect a pipe having one end communicating with the outside air to the cleaning chamber.
The connection position of the pipe with the cleaning chamber is preferably at the upper part of the cleaning chamber in order to prevent organic solvent vapor from leaking from the lower part of the cleaning chamber, since organic solvent vapor is generally heavier than air.

１〜５インチであれば十分にその目的を達する。This pipe has a function of adjusting the atmospheric pressure inside and outside the cleaning chamber as described above, and also allows the atmosphere in the cleaning chamber to be replaced more quickly. For example, during cleaning, it is preferable that the atmosphere in the cleaning chamber be in a saturated state of the organic solvent vapor or in a state close thereto. Therefore, when the organic solvent vapor is changed from the unsaturated state to the saturated state, it is necessary to remove non-condensable gas such as nitrogen gas from the cleaning chamber when using air or a flammable solvent in the cleaning chamber. For this purpose, it is efficient to pull out the pipe connected to the cleaning chamber. Further, when connecting a pipe to the upper part of the cleaning chamber, it is most suitable to incline the ceiling of the cleaning chamber and provide the pipe at the top of the ceiling.
The diameter of these pipes is not particularly limited, but usually,
One to five inches is sufficient for that purpose.

けることが好ましい。Further, as shown in FIG. 5, it is preferable to connect the above-mentioned pipes through a buffer chamber 29 in order to prevent leakage of the organic solvent vapor in the cleaning chamber. The size of the buffer chamber is not particularly limited.
It is preferable that the number be twice or more because the buffer function can be sufficiently provided. Although the internal structure of the buffer chamber is not particularly limited, it is preferable that the space between the inlet and the outlet is divided into a plurality of sections, and each compartment is connected by a small-diameter pipe or hole. By doing so, the movement of gas in the buffer chamber is prevented, and the inflow of outside air into the cleaning chamber and the leakage of the organic solvent out of the cleaning chamber can be effectively prevented. Further, the buffer chamber is preferably provided at a position higher than the washing chamber.

法である。As a method of reliably continuing the state of avoiding the danger of flammability in the cleaning chamber during the operation after the replacement with nitrogen gas, a small amount of water is supplied from the upper part of the cleaning chamber to the pipe finally communicating with the atmosphere. It is a more preferable method to continuously run a small amount of nitrogen gas and to operate in a state substantially sealed with nitrogen.

浄することができる。When flammable hydrocarbons, petroleum, etc. are used as the organic solvent, there is a possibility that the atmosphere in the cleaning chamber may fall within the explosion limit due to the incorporation of air. As a method of removing static electricity or a method of reducing the oxygen concentration, measures such as a method of diluting with a nonflammable vapor such as a nitrogen vapor have to be taken. However, by providing the above-described buffer chamber, the movement of gas can be almost completely prevented while maintaining the same pressure in the cleaning chamber and the outside air. Therefore, it is possible to prevent air from entering the cleaning chamber. For this reason, even if a flammable organic solvent is used, it can be safely washed.

比して非常に少ない量であった。Example 4 Using the same washing apparatus as used in Example 1, a stainless steel having a thickness of 0.1 mm and a width of 300 mm was used as an organic solvent as a hydrocarbon solvent mainly composed of decane and dodecane. A continuous steel strip of steel was cleaned. Line speed of continuous metal strip: about 60 m / min, spray rate: about 2 l / min. (Total spray rate: 36 l / mi)
n), the number of rotations of the brush was about 700 rpm, and the drying was performed by a one-time method in which air at about 80 ° C. was blown. Nitrogen gas was supplied from the valve 26 in advance, and air was replaced so that the oxygen concentration in the cleaning chamber became about 1%. The solvent vapor leaking from the cleaning chamber was introduced into the exclusion facility by the exhaust gas suction pump 11 through the valves 14 and 15. The valve 17 was closed and the valve 16 was opened to communicate with the outside air. As a result of obtaining the solvent loss amount from the solvent vapor sampled from the valves 22 and 25, the total amount of the valves 22 and 25 was about 0.5 kg / H.
r. When the organic solvent was a hydrocarbon solvent containing decane and dodecane as main components, the amount of leakage was very small as compared with methylene chloride.
