Description

oil spill treatment equipment

technical field

The utility model belongs to oil spill treatment equipment.

Background technique

The current oil spill treatment technologies mainly include biological methods, chemical methods and physical methods. Biological methods include strain method and nutrient method. The disadvantages of this method are: when the oil spill accident is large, the oil film will become very thick. At this time, the supply of nutrients and oxygen is insufficient, and the growth of bacteria is inhibited. It is too long. In addition, because the use of super engineering bacteria is still in the transition period from basic research to practical research, and there are still many problems to be solved in practical application, therefore, this method is still in its infancy and cannot be fully obtained. practical application. Chemical methods include combustion method and treatment agent method. The disadvantage of combustion method is that it not only wastes precious energy, but also easily produces secondary pollution (mainly thermal pollution and air pollution); treatment agent method is also prone to secondary pollution. There are limitations in practical application. Physical methods include adsorption method and mechanical method, among which the adsorption method is the oil-absorbing felt prepared by the adsorption material ("On-site production and performance of oil-absorbing felt" [J]. Industrial Textiles, 1993, 5:42-43.), oil-absorbing felt However, there are disadvantages such as low recovery rate; mechanical methods include various types of oil skimmers ("Summary of Ship Oil Pollution Treatment Methods." [J]. Tianjin Navigation . 2010. 1-5), multi-functional marine oil spill treatment device ("Multifunctional Marine Oil Spill Treatment Device Design" [J]. Ship Engineering. 2009, 31: 131-135.), hot air balloon oil slick collection device , offshore forklift oil slick collector, submersible oil slick collector ("Conceptual Design of Offshore Oil Spill Collection Device" [J]. Ship Engineering. 2009,31: 136-139.) and oil boom ("Oil Containment Mathematical simulation of the effect and shape of booms under various sea conditions" [D]. Dalian Maritime University. 2007 .), including ordinary double-body oil booms ("Introduction to the performance evaluation test of double-body oil booms" [J ]. Transportation and Environmental Protection. 1988,1: 35-37.), etc., most of these mechanical methods have shortcomings such as low oil absorption efficiency and slow oil recovery. For example: the oil boom disclosed in "Oil-absorbing Felt Oil Boom" (terminated Chinese Patent No. 98241919) can roll and absorb oil under the impact of water flow, and can be used after the oil is fully absorbed by an extruder to squeeze out the oil. However, the limitation is that when a large-scale oil spill occurs, the spilled oil cannot be recovered efficiently in a short period of time, and continuous operation cannot be carried out continuously.

Utility model content

The technical problem to be solved by the utility model is to provide an oil spill treatment equipment with high oil absorption rate and capable of circulating oil spill treatment operations.

The utility model solves the above technical problems with the following technical solutions:

The oil spill treatment equipment consists of an inner oil boom and an outer oil boom, the inner oil boom is an inflatable oil boom, the outer oil boom is an adsorption oil boom; the outer The oil boom is dragged and squeezed by the rollers installed on the towing operation ship; the towing operation ship also has an oil suction pump for extracting the concentrated oil trapped in the inner oil containment boom and an oil-water separation for separating the thin oil absorbed by the outer oil containment boom device.

The lower end of the inner oil boom has a counterweight.

The outer oil boom is made of bagasse material, with a counterweight at the lower end and a floating body at the upper end.

The oil spill treatment equipment of the utility model uses the bagasse material with high oil absorption rate and the double-body oil containment boom prepared by the inflatable inner layer oil containment boom, which can not only treat the oil spill efficiently, but also has a high recovery rate of the oil spill, It realizes circulation operation and can be widely used in emergency treatment of oil spill accidents and oil spill recovery.

Detailed ways

The utility model is based on the high-efficiency oil absorption performance of the bagasse oil-absorbing material, and the bagasse oil-absorbing material is made into an outer oil containment boom, and the outer layer oil containment boom and the inflatable inner layer oil containment boom form a two-body oil containment boom; the inner layer oil containment boom The main function of the column is to prevent the spilled oil from spreading, enclose the spilled oil, make the thickness of the spilled oil reach a certain thickness, and then collect the thick oil in this layer by pumping. The remaining layer of thin oil after the treatment of the inner oil boom is absorbed by the adsorption of the outer oil boom made of bagasse oil-absorbing material. Using the transmission force brought by the two rollers installed on the ship, the operation After the circle, it leaves the sea surface and is squeezed between two rollers. The oil and water squeezed out enter the oil-water separator under the rollers along the oil receiving tank for oil-water separation, and finally achieve the purpose of oil spill recovery. The entire operation surface needs to be towed by a workboat for sea sweeping operations, and high oil spill treatment efficiency can be achieved through repeated sea sweeping.

In the oil spill treatment equipment in the figure, the inner oil boom 2 is an inflatable oil boom, and the outer oil boom 3 is an adsorption oil boom; Dragging and squeezing; there are also oil suction pumps 4 for extracting the thick oil surrounded by the inner oil boom and oil-water separators 6 for separating the thin oil adsorbed by the outer oil boom on the towing operation ship.

The lower end of the inner layer oil boom has counterweight 7. The outer oil boom is made of bagasse material, with a counterweight 9 at the lower end and a floating body 8 at the upper end. The counterweight and floating body ensure the normal operation of the oil boom and efficient oil retention.

When dealing with oil spills, the oil spill treatment equipment of the utility model continuously sweeps the sea through the dragging of the hull 1, and the spilled oil enters the range of the oil containment boom, and is first fenced by the inner oil containment boom 2, and the oil spill reaches a certain level. This part of the spilled oil is recovered by the pumping action of the oil suction pump 4; at the same time, the remaining part of the thin oil is absorbed by the adsorption of the outer oil enclosure boom 3 made of bagasse oil-absorbing material, and the outer oil enclosure Under the driving action of the roll 5, the bar has absorbed the remaining part of the thin oil after a week of circulating operation at sea, and then the thin oil is squeezed out by the pressing action of the roll, and this part of the thin oil enters the bottom of the roll along the oil receiving tank. The oil-water separator 6 separates the oil and water, and the outer oil boom after squeezing enters the next sea-sweeping cycle.

The inner oil boom 2 can adopt the following main technical parameters: overall height 2000mm, dry string 600mm, draft 1100mm, length 200m, thickness 200mm, counterweight radius R=0.1m.

The outer oil boom 3 can adopt the following main technical parameters, total height 2000mm, dry string 600mm, draft 1100mm, length 420m, thickness 300mm, floating body radius R1=0.2m, counterweight radius R2=0.1m.
