る（第５図参照）。In addition, to explain one embodiment, the oil 2 in the oil storage tank 1 is discharged by the oil dispensing pump 3, and at a place where the oil level has fallen slightly above the suction jacket 4 of the oil dispensing pump 3, Due to the relationship between the effective suction head (NPSH) and the internal pressure of the oil storage tank 1, no more oil 2 can be discharged, so the oil discharge pump 3 is stopped (L position) (see Figure 2).Then, the suction jacket is pumped with spring water or water supply. After increasing the water pet 5 to near the top of 4 and raising the oil level (3rd
(See figure) Operate the oil dispensing pump 3 again to dispel the remaining oil 2 on the water pet 5 (see Fig. 4). After stopping the oil dispensing pump 3, operate the drain pump T to discharge the remaining oil 2 from the water pet 5. By draining the water, a small amount of remaining oil 6 on the water pet 5 is accommodated in the pump pit 8 (see FIG. 5).

マンホール１５を設ける。The operation of the drain pump 7 sends the oil 6 and water 9 in the pump pit 8 to the oil-water treatment tank (see Fig. 6). The subsequent work will be explained based on Figure T. The existing pro-action pipe used for interpolation of instruments will be used as the vapor recovery pipe 10 and the steam feed pipe 11, and vapor will be recovered from the vapor recovery pipe 10. At the same time, steam is sent into the oil storage tank 1 from the steam feed pipe 11 to replace vapor with steam. The steam in the oil storage tank 1 is brought into a saturated state to melt the oil adhering to the rock surface or pipe surface of the oil storage tank 1, and the heated vapor melts the sludge accumulated at the bottom and discharges it to the oil water treatment tank. After confirming that no vapor is contained using hydrocarbon concentration meters installed inside and outside the oil storage tank 1, a ventilation proar 12 is attached to the steam feed pipe 11, and air is stored through the ventilation proar 12. The steam is sent into the tank 1 and is recovered from the pipe 10, replacing the steam with air. The steam is cooled and condensed to turn it into water. The waste liquid is discharged to the oil-water treatment tank, and then the steam and air are completely replaced. After confirming that there is sufficient oxygen in the oil storage tank 1 using oxygen concentration meters installed inside and outside the oil storage tank 1, workers are allowed to enter safely. 13 is access tunnel 14 and oil storage tank 1
A manhole 15 is provided through which workers can go in and out using a concrete plug that separates the area.

点検をすることができる等の特徴を有するものである。In this application, after discharging the oil in the oil storage tank as described above, the oil and water accumulated in the pump pit are discharged into the oil water treatment tank, and then, while recovering vapor, steam is sent in to replace the vapor and steam, and the oil and water in the oil storage tank are The steam is saturated to melt the oil adhering to the rock surface or pipe surface of the oil storage tank, and the heated vapor melts the sludge that has accumulated at the bottom and is discharged into the oil-water treatment tank. This method uses existing equipment to eliminate the dangers of fire, explosion, etc. as it cools and condenses water, drains the waste liquid into an oil-water treatment tank, and then completely replaces it with steam and air. By opening the oil storage tank and sending in steam, it is possible to melt and clean the oil adhering to the rock surface or pipe surface of the oil storage tank.Furthermore, since vapor is heavier than steam, the hot steam is used to lower the oil and remove the oil that has accumulated at the bottom. The sludge can be melted and flushed away, and then air can be pumped in to cool the steam, condense it, and wash it out with water, allowing workers to safely enter inside and perform repairs.
It has characteristics such as being able to be inspected.
