Embodiment 1

[0032] see Figure 1 to Figure 4 Embodiment 1 of the present invention provides an imitation jellyfish offshore oil cleaning device based on air flotation technology, including a housing 1, a water inlet body, a frequency conversion motor 9, a stirring impeller 4, an air bag 8, and an air pump ( Figure 1 to Figure 4 Not shown in), drainage impeller 5, oil-water interface detector 11 and controller 10.

[0033] Wherein, the housing 1 is an axisymmetric structure, its main part is cylindrical, and the bottom is in an inverted cone shape, which can increase the stability of the device and is more conducive to the formation of a vortex inside the housing 1 . A drain port is opened at the bottom of the housing 1 for draining the separated water out of the housing 1 . When in use, since the shell 1 does not bear a large load, good impact strength and hardness, moderate tensile strength and dimensional stability are required, and the price of the material is required to be moderate...

Embodiment 2

[0056] Embodiment 2 of the present invention provides an imitation jellyfish offshore oil removal system based on air flotation technology, including at least one of the above-mentioned imitation jellyfish offshore oil removal device and oil removal mother ship based on air flotation technology. Among them, the shell of each imitation jellyfish offshore oil cleaning device is connected to the oil cleaning mother ship through the oil guide pipe. The oil cleaning mother ship is equipped with an oil suction pump and an oil storage tank. The oil suction pump is used to pump the oil separated by each imitation jellyfish offshore oil cleaning device into the storage tank. Oil tank for oil recovery.

[0057] The split design of the oil storage tank and the housing 1 effectively improves the oil cleaning efficiency. When in use, put the bionic jellyfish oil cleaning devices on both sides of the oil cleaning mother ship, make a side-by-side matrix arrangement, turn on the oil suction p...

Abstract

The invention relates to a jellyfish imitation offshore oil clearing device and system based on an air flotation technology. The jellyfish imitation offshore oil clearing device comprises a shell, water inlet bodies, a frequency conversion motor, a stirring impeller, a drainage impeller, an air bag, an air pump, an oil-water interface detector and a controller; the main body of the shell is cylindrical, and the bottom of the shell is inverted cone shaped; the water inlet bodies comprise a plurality of water inlet pipelines, and a floating body for increasing buoyancy is arranged at a water inlet opening of each water inlet pipeline; the frequency conversion motor is arranged on the upper part of the top of the shell, and an output shaft of the frequency conversion motor is coaxially arranged inside the shell in a penetrating mode; the stirring impeller and the drainage impeller coaxially sleeve the output shaft of the frequency conversion motor in a spaced mode; the air bag is arrangedinside the shell, and the air pump is arranged outside the shell, and connected with the air bag; the oil-water interface detector is arranged inside the shell; and the controller is electrically connected with the frequency conversion motor and the oil-water interface detector, and generates corresponding frequency conversion motor control instructions and sends according to feedback informationof the oil-water interface detector. According to the jellyfish imitation offshore oil clearing device based on the air flotation technology, the wind and wave resistance properties are good, the recovery efficiency is high, and the jellyfish imitation offshore oil clearing device is suitable for thicknesses with different oil layers.

Description

technical field [0001] The invention relates to the technical field of oil collection, in particular to an imitation jellyfish offshore oil cleaning device and system based on air flotation technology. Background technique [0002] With the development of society, human's demand for oil has increased rapidly, and offshore oil exploration and exploitation have also risen rapidly. This situation has increased hidden dangers for oil spills at sea. The pollution caused by the oil spill to the ocean is serious and long-lasting. Because the oil layer has the function of isolating the air, the fish and other aquatic organisms in the water will die due to suffocation, and the plants in the water will be corrupted due to lack of oxygen. Reduce the self-cleaning capacity of the ocean. Therefore, the development of a new type of offshore oil cleaning device is of great significance for protecting the earth's environment and protecting marine organisms. [0003] The existing offshore ...
