Abstract

PURPOSE:To recover and separate a large quantity of oil and to reutilize recovered oil as it is by naturally separating sucked oil from water and sucking and recovering the floated oil component. CONSTITUTION:The drain port 3 from a sucking-up pump P1 having an outflow oil suction port 1 connected thereto is connected to a sucking-up tank chamber T1 and the oil supply port 5 connected to a purifier P3 is provided to a sucking-up tank chamber T2. A reticulated separator S is provided between the sucking-up tank chambers T1, T2 and water filters F1, F2 are provided at the intermediate height positions of both chambers. The purified oil discharged from the purifier P3 is discharged to a purifying tank PT from an oil discharge port 6. An oil-water separation tank consists of tank chambers T3-TN and the outflow oil and water introduced into the lower part of the tank chamber T3 from the lower part of the sucking-up tank chamber T2 through an open communication port A flows in the chamber T3 from a partition plate 8 to be introduced into the lower part of the tank chamber T4 through an open communication port and flows in the tank chamber T4 from a partition wall 9 and successively reaches the tank chamber TN in the same way. A filtered water discharge pump P2 is provided to a final tank to suck filtered water from the tank chamber TN and the filtered water is discharged from a drain port 11.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for recovering oil when oil is spilled in a ship accident or the like.

[0002]

2. Description of the Related Art Conventionally, it has been very difficult to collect spilled oil. Therefore, it is necessary to prevent it from spilling outside by surrounding it with an oil fence and neutralizing and sinking it with an adsorption mat or chemicals. Is.

[0003]

However, the current situation is that the use of chemicals causes pollution problems, and even if an accident occurs, the chemicals cannot be used.

[0004]

The present invention is a means for efficiently recovering oil that has flowed out to the sea, rivers, and the like, and is one in which the absorbed oil and water are naturally separated and the floating oil is sucked and recovered.

EXAMPLES Examples will be described with reference to the drawings.
In FIG. 1, a suction pump P1 connected to an oil spill inlet 1 is installed in a suction pump chamber 2, and a drainage port 3 from the suction pump P1 is connected to an upper side surface of a suction tank chamber T1 which is a first-stage tank. A mesh separator S is installed at the boundary between the suction tank chamber T1 and the suction tank chamber T2 which is the same tank.

Water filters F1 and F2 are installed at intermediate height positions of the suction tank chambers T1 and T2.

Water filter F2 in the suction tank chamber T2
A fuel filler port 5 connected to a cleaner P3 installed in the cleaner chamber 4 is provided on the upper side surface.

The lower part of the suction tank chamber T2 has an opening connection structure to the tank chamber T3 of the oil / water separation tank which is the next tank.

The clean oil discharged from the cleaner P3 provided in the cleaner chamber 4 is formed by connecting the oil discharge port 6 to the clean tank PT. Sluts such as dust from the purifier P3 are guided to the slat tank ST through the slat discharge port 7.
Water discharged from the purifier P3 is guided to the upper part of the suction tank T2 through the discharge port 12.

The oil / water separation tank is composed of tank chambers T3 to TN chambers, and the spilled oil water introduced from the lower portion of the tank chamber T3 is made to flow from a partition plate 8 provided to an intermediate height position and further opened to the lower portion of the tank chamber T4. It has a connecting structure, and a partition plate 9 is provided in the tank chamber T4 in the same manner as in the previous stage, and the tanks T4 are sequentially repeated to N tanks.

A drainage pump chamber 10 is provided in the final tank, and a filtered water discharge pump P2 is provided so that the filtered water led out from each tank chamber is sucked and drained to the outside through a drainage port 11.

When this is used, water is preliminarily filled up to the surface L, and the spilled oil is sucked up from the suction port 1 by the pump P1 and put into the tank chamber T1 so that the oil containing seawater is reticulated. The momentum flowing into the separator S is calmed down, and oil and water are naturally separated. The water filters F1 and F2 prevent oil from flowing into the lower part.

The oil floating on the upper part of the tank chamber T2 is cleaned by the purifier P.
The water discharged from the purifier P3 after being cleansed and separated in 3 and sent to the clean tank PT is sucked through the discharge port 12 to the suction tank T2.
Guided to the top. Also, slats such as dust are distributed to the slatch tank ST.

The seawater and water pushed below the tank chambers T1 and T2 pass through the opening communication port A and are guided to the tank T3 of the next water tank without being completely separated. The oil water guided at this time flows to the upper part by the partition plate 8 provided to the intermediate high position in the tank T3, and is naturally separated again. By repeating this operation several times, the purified water is discharged to the outside through the drainage pump P2.

[0015]

By using the apparatus of the present invention, a large amount of oil can be recovered and separated, the oil can be prevented from being contaminated, and the recovered oil can be reused as it is.

If the structure of the present invention is used in the hold of the ship, it will be effective as an oil spill recovery ship for preventing oil pollution of the sea or lake.

If this device can be carried on a vehicle and moved, it can be used as an oil spill recovery vehicle in a river.
As described above, it has a very wonderful effect.
