Description

OIL ABSORPTION PAD

BACKGROUND OF THE INVENTION 1. Field of the Invention The present disclosure relates to an oil-absorbing filter used to remove oil spread in the sea and the like.

Unless otherwise indicated herein, the description set forth in this identification section is not prior art to the claims of this application and is not to be construed as prior art as described in this identification section.

Generally, in order to remove oil such as Bunker C oil that has spread to the sea by collision accident or sinking accident at sea, i) a method of spraying oil emulsifying agent neutralizing oil and ii) a method of spraying oil absorbing oil And iii) a method of installing an oil prevention film so as to prevent the spread of oil from spreading.

Although the oil spreading method described above can neutralize oil, there is a possibility that the chemical component of the oil spreading agent may contaminate the water quality secondarily. In the above-mentioned method of installing the oilproof layer, But it does not remove the oil that is practically spread to the sea. On the other hand, the above-described oil sorbent spraying method is the most effective because it can substantially remove oil spread in the sea and is widely used.

The conventional oil-absorbing film 10 shown in Fig. 1 is a very thin sheet composed of two sheets of non-woven fabric 11, 12 made of polypropylene and a polyester sheet 11 filled therebetween.

Since the conventional oil absorbing pouch 10 is relatively thin and light in thickness, it can not be thrown away, and when it is thrown from a floating vessel in the sea, it does not fly in the throwing direction due to the influence of the wind, There is a problem.

In addition, since the conventional oil absorption apparatus 10 has a very thin thickness and a soft and soft nature, most of the oil absorption apparatuses that have been thrown up reach the sea in a collapsed state and the efficiency of the control is lowered. Therefore, There is a problem in that a user must unfold the oil absorbing foam which is folded on the sea from the ship.

Disclosure of the Invention Disclosure of the Invention Problems to be solved by the present invention are to solve the problems of the conventional oil-absorbing filter. First, in order to maximize the surface area of the oil-absorbing membrane dropping on the sea, a large amount of oil is adsorbed in a short time. Second, When dropping, the air resistance is minimized so that it is dropped exactly where desired.

Further, it is obvious that the present invention is not limited to the above-described technical problems, and another technical problem may be derived from the following description.

There is provided a lubricant absorbent comprising a sheet having at least one sheet having an oil adsorbing ability and an elastic material having a predetermined elastic restoring force provided on the sheet.

According to the solution disclosed in this specification,

First, it is possible to adsorb a large amount of oil in a short time by maximizing the surface area without collapsing while falling down on the sea while maintaining the thin and smooth and flexible nature of the oil absorbent. Second, when the oil absorbent is dropped into the sea, It can be dropped exactly where it is.

Therefore, the use of the oil-absorbing agent disclosed in the present specification can reduce the required amount of the oil-absorbing agent according to the control, and shorten the time for the control and easy recovery.
