Problems solved by technology

These three oil spill treatment methods have various advantages and disadvantages. Among them, the biological treatment method is more suitable for oil spill treatment, but it cannot realize the recovery of leaked crude oil and may cause the risk of biological invasion. Compared with chemical and biological methods It is said that the physical method can realize the recovery of leaked crude oil and effectively reduce the damage to the environment caused by the leaked oil, but the water content of the recovered crude oil by the physical method is too high, resulting in a decrease in the quality of the recovered crude oil

Embodiment 1

[0031] see Figure 1-8 as shown,

[0032] A marine oil spill cleaning and recovery device, comprising:

[0033] Hull 100, the first fixed rod 150 is fixedly connected to both sides of the hull 100, the end of the first fixed rod 150 is connected with the monitoring component 140 arranged in the water through the rope body 130, the monitoring component 140 and the processor 110 arranged on the hull 100 Wireless connections,

[0034] Wherein, the hull 100 is fixed with the oil collecting tank 10, the third oil filtering tank 20, and the second oil filtering tank 30, the oil collecting tank 10 is connected with the third oil filtering tank 20 through the first oil discharge pipe 22, and the third oil filtering tank 20 is connected through the second connecting pipe. 34 is connected with the second oil filter tank 30, and the second oil filter tank 30 is connected with the first oil filter tank 40 arranged on the water surface at the rear side of the stern of the hull 100 throug...

Embodiment 2

[0046]When a marine oil spill cleaning and recovery device of the present invention is actually used: after a leak occurs in the sea area, the ship hull 100 is equipped with equipment to drive to the oil spill area for emergency treatment, so as to avoid greater damage to the marine environment in the area.

[0047] First, to ensure the maximum recovery of the leaked oil by tracking the leaked oil: use the hull 100 to sail on the sea surface of the oil spill, the current velocity meter on the monitoring component 140 can drift with the sea surface water body, the current velocity meter sends the positioning signal to the processor 110, and at the same time the anemometer acquires The monitoring data is sent to the processor 110 together, and the processor judges the oil film drift speed formed by the leaked oil on the sea surface according to the data sent by the current meter and the anemometer, and combines the locator to judge the drift direction of the oil film, so as to rea...

Embodiment 3

[0051] Oil spill recovery simulation test:

[0052] Carry out group oil spill recovery simulation test in two water tanks, set up experiment group and control group separately, experiment group adopts the device of the present invention 1 and the recovery method of embodiment 2 to carry out recovery treatment, control group adopts polyurethane foam board to carry out oil adsorption Recycle.

[0053] The size of the water tank is 10 meters long x 6 meters wide x 1 meter high. The two tanks have the same size. The leaked crude oil used in the simulation is dehydrated in advance and configured as oil with a water content of 10% as the leaked crude oil. The leak point is located at the center of the tank It is set as the leak point, and oil recovery starts 4 hours after the oil spill, which is used to simulate the time it takes for the emergency unit to rush to the leaking sea area after the oil spill occurs, and the oil diffusion situation during this period. Carry out oil recov...

Abstract

The invention discloses a marine oil spill clearing and recovering device, and belongs to the technical field of marine oil spill pollution treatment. The device comprises a ship body, wherein the twosides of the ship body are fixedly connected with first fixing rods, the end portions of the first fixing rods are connected with monitoring assemblies arranged in water through cable bodies, and themonitoring assemblies are in wireless connection with a processor on the ship body; and the ship body is fixedly provided with an oil collecting tank, a third oil filtering tank and a second oil filtering box, wherein the oil collecting tank is connected with the third oil filtering tank through a first oil discharge pipe, the third oil filtering tank is connected with the second oil filtering tank through a second connecting pipe, and the second oil filtering tank is connected with a first oil filtering tank arranged on the water surface of the rear side of the stern of the ship body througha first connecting pipe. According to the marine oil spill clearing and recovering device, the drift direction of oil films can be effectively detected, so that the sea surface and the oil films areseparated, thus avoiding the sea surface from forming the oil films with a certain coverage range and reducing petroleum leakage sea area pollution and influence on creatures; and in addition, the water content rate of recovered crude oil can be reduced through multi-stage treatment.

Description

technical field [0001] The invention belongs to the technical field of marine oil spill pollution control, and in particular relates to a marine oil spill cleaning and recovery device. Background technique [0002] With the increasing demand for oil in all countries in the world, the trade of petroleum products is on the rise, leading to the rapid growth of the oil transportation industry, especially the largest amount of oil transported by ships, accounting for more than 60% of the oil transportation. The development of marine oil transportation has also drawn public attention to oil pollution in the ocean. As a global pollutant, petroleum is entering the ocean in far greater quantities than other pollutants. According to statistics, of the 3.2 billion tons of oil produced in the world every year, about 1 / 1000 or 3.2 million tons enter the marine environment. Usually, 1 ton of oil can form a covering area of ​​oil film on the sea. The resulting large area of ​​oil film wi...
