Description

A collection device for oil spills at sea

technical field

The utility model relates to an oil collection device, in particular to a collection device for oil leakage at sea.

Background technique

In recent years, with the development of the global economy, the amount of oil extracted at sea and the amount of crude oil transported by sea has increased sharply. Oil tankers have been damaged by shipwrecks and oil spills have occurred frequently. If they are not handled well, they will seriously pollute the environment and damage the Various creatures of the sea. The way of crude oil leakage pollution is regional plane pollution at first, and then gradually expands the contaminated area by penetration and expansion. Collect, separate and purify, and recover crude oil.

At present, the commonly used methods are as follows: The first one is to use natural degradation, which is used when the amount of leakage is relatively small and the hazards caused can be ignored. The second method is the combustion method, which is adopted when the leakage of crude oil is concentrated and will not cause a fire. The third is the chemical elimination method, which uses chemical agents to convert crude oil into other non-polluting or less environmentally harmful substances. This method has secondary pollution, and the environmental risk is still relatively large. The fourth is the microbial degradation method. Adding special bacteria to the oil spill area is an upgraded version of the natural degradation method. It is currently the recommended method for dealing with large-scale offshore oil spills and other accidents, but the efficiency is low.

Detailed ways

Below, the technical solution of the utility model will be further described in conjunction with the accompanying drawings and specific embodiments, but the utility model is not limited to the following embodiments.

See attached picture. A collection device for offshore oil spills, which is formed by connecting several dam bags 1. The dam bags can be made of refractory rubber materials. The cavity in the center of the dam bag is an inflatable air bag 2, and the periphery of the dam bag is thicker. The left and right sides of each dam pocket are provided with connecting strips 3, and the said dam pockets are connected in pairs by the connecting strips 3 on both sides to form an annular dam. The dam bag 1 is provided with an inflation port 3 communicating with the inflatable airbag 2, and after the inflatable airbag 2 is filled with gas through the inflation port 3, the dam can be suspended on the sea surface.

In the event of an oil spill, the specific gravity of oil is smaller than that of water, and the oil will float above the water. When in use, the inflated dam will contain the leaked oil in the dam, and part of the floating dam is located underwater. Part of it is above the water. The collection device for offshore oil leakage of this embodiment can be used when oil leakage occurs when oil is drilled at sea, and can also be used when oil leakage occurs on an oil tanker. The outer diameter and height of the dam body can be determined according to actual needs, such as Depends on the size of the well. When the collection device is not in use, it can be sunk on the seabed or suspended underwater, and it can be fixed in place with anchor ropes and tugboats, and it can also be temporarily transported to the accident site when an accident occurs. The oil in the dam should be pumped out in time with an oil pump to avoid excessive storage and overflow.

In order to make the inflated back dam device float in a certain position and maintain its balance, a counterweight 9 can be hung at the bottom of the dam bag 1, and the bottom of the dam bag is provided with a hanging hole 8 for hanging the counterweight.

The dam bag 1 can be inflated independently. However, due to the huge volume of the dam, for the convenience of inflation, the dam can be divided into several inflatable units that can be inflated independently, and the inflatable unit can be composed of a dam bag or a plurality of dam bags. In an inflatable unit composed of a plurality of dam bags, the inflation ports 3 of the two connected dam bags can be connected by an inflatable tube 7, and the inflation gas source gas I enters from at least one of the inflatable tubes. As shown in Figure 1, two adjacent dam bags in this embodiment communicate with each other through a three-way pipe, and communicate with the inflation gas source I. As shown in Figure 4, the inflation port of this embodiment dam bag is communicated with a main inflation pipe 10 through the inflation pipe 7, and the inflation gas source gas I enters from the main inflation pipe.

In order to make the connection between adjacent dam pockets sealed and stable, the connecting strips between adjacent dam pockets can be connected and fixed through the splint 5, that is, one or more splints are superimposed on the front and rear sides of the overlapping connecting strips 5. The splint 5 is clamped and fixed by bolts passing through the connecting holes 6 on the connecting bar.

In order to prevent damage to the dam bag when the oil burns, the surface of the dam bag close to the water surface can be coated with high-temperature resistant materials, or metal materials such as stainless steel can be used to make the dam bag to resist the high temperature of oil burning and improve high temperature resistance.
