Due to the structure of rotating metal blades such as rotors and screws at high speed, the optimum vacuum degree cannot be obtained unless the gap between the blades is 1mm or less. If the balance of the blades is lost, there is a risk of contact accidents, and it is extremely dangerous when used for highly flammable hydrocarbons.

に補給される。After the ultrasonic cleaning of the object A to be cleaned,
The cleaning tank 1 is decompressed by the vacuum pump 6 via the gas-liquid separation tank 4 to be in a vacuum state, so that the object A to be cleaned in the cleaning tank 1 is vapor-cleaned. That is, when the cleaning tank 1 is depressurized by the vacuum pump 6 via the gas-liquid separation tank 4 to be in a vacuum state, the steam generation tank 4 is also depressurized to be in a vacuum state,
In this vacuum state, the cleaning liquid is heated to a high temperature (for example, about 80 ° C. to 140 ° C.) by the electric heater 11 to generate cleaning vapor. And the steam generation tank 4
From the above, only the cleaning vapor is sucked into the cleaning tank 1 and is sprayed from the ceiling of the cleaning tank 1 onto the low-temperature cleaning target A for a certain period of time. In this way, when the cleaning vapor is sprayed on the low temperature cleaning target A,
Since the cleaning vapor is condensed when it comes into contact with the low-temperature cleaning target A, the cleaning target A can be steam-cleaned and the cleaning target A can be heated. During the steam cleaning, the gas-liquid separation tank 5 is also in a depressurized state.
The cleaning vapor of (1) passes through the supercooling condenser 12 and is sucked into the gas-liquid separation tank 5. At this time, the cleaning vapor is cooled by the supercooling condenser 12 to be separated into a small amount of uncondensed gas having a low temperature and a large amount of condensed liquid, and the uncondensed gas is sucked into the vacuum pump 6. On the other hand, the condensed liquid is collected in the gas-liquid separation tank 5 and then returned to the buffer tank 2 by the liquid feed pump 13. The uncondensed gas sucked by the vacuum pump 6 is sent to the oil removal filter 14 and the oil removal filter 14 removes hydrocarbons. Further, the uncondensed gas sucked by the vacuum pump 6 is dissolved or mixed in the water for water sealing as an oil component in the vacuum pump 6, but passes through the oil removal filter 14 together with the water for water sealing to obtain the oil water. Since the oil component contained in the water for the breeze of the vacuum pump 6 is removed in the oil removal filter 14, the oil component not removed in the oil removal filter 14 is collected in the separation tank 15. At the same time, it is separated and floats on the surface, and is recovered in the oil recovery tank 17 together with the overflow water. On the other hand, the water for water sealing after the oil content in the oil / water separation tank 15 is sufficiently removed is cooled by the cooling mechanism 18 provided in the oil / water separation tank 15, and then the makeup pump 16 makes the vacuum pump 6
Will be replenished.

残留洗浄蒸気を回収させる。After the steam cleaning of the cleaning target A is completed, the cleaning tank 1 is evacuated by the vacuum pump 6 to dry the cleaning target A. At this time, the object to be cleaned A is heated at the time of steam cleaning, and thus is quickly dried. Also in this case, the residual cleaning vapor in the cleaning tank 1 is recovered in the same manner as the above-described vapor cleaning.

操作を終了する。Even after the vacuum drying is completed, the atmospheric pressure release valve 9 is opened while driving the vacuum pump 6 for a further predetermined time, so that the residual hydrocarbon in the cleaning tank 1 is sucked into the vacuum pump 6 together with the atmospheric air. Then, the series of operations is terminated by significantly lowering the explosion limit concentration of hydrocarbons (about 0.8 to 5%).

In parallel with this cleaning and drying operation, the cleaning liquid B containing the contaminants after cleaning is regenerated. That is, the cleaning liquid B containing the pollutants after cleaning is stored in the buffer tank 2, but the cleaning liquid B containing the contaminants after cleaning flows into the vacuum distillation regeneration tank 3 and is heated by the electric heater 10 under reduced pressure. By heating, the cleaning liquid B containing the contaminants after cleaning is vacuum-distilled and regenerated. In this way, the cleaning liquid B containing the contaminants after cleaning is vacuum-distilled and regenerated in the vacuum distillation / regeneration tank 3 to maintain the purity of the cleaning liquid B in the buffer tank 2.

常に危険性が少なくて安全性に優れている。According to the cleaning apparatus of the present invention, the water-sealing type vacuum pump 6 is used as the pressure reducing means, and the cleaning tank 1 is used.
Since the supercooling condenser 12 is provided between the cleaning tank 1 and the gas-liquid separation tank 5, the cleaning steam exhausted from the cleaning tank 1 is sucked by the vacuum pump 6 only for a small amount of hydrocarbon gas having a low temperature to seal the water. It can be discharged out of the system in a state of being dissolved or mixed in water for use. Since a small amount of the hydrocarbon gas having a low temperature is dissolved and mixed in the water for sealing the water of the vacuum pump 6, the concentration of the hydrocarbon can be reduced, and the danger is very low and the safety is high. Is excellent.

Since the circulation line is formed by connecting to the vacuum pump 6 via the oil / water separation tank 15 provided with 8 and the makeup water pump 16, the water for water sealing used in the vacuum pump 6 is replaced with the oil removal filter 14 After the oil component (hydrocarbon) is removed in the oil / water separation tank 15, it can be cooled by the cooling mechanism 18 and supplied to the vacuum pump 6 by the makeup water pump 17. As a result, hydrocarbons can be easily recovered, and the water for water sealing of the vacuum pump 6 can be reused by removing the naturally-evaporated portion, and the water for water sealing can be saved.
