Description

A new type of offshore oil spill treatment equipment based on double crawlers

technical field

The invention relates to a new double-shoe-based offshore oil spill treatment equipment, in particular to a double-shoe-based new marine oil spill treatment equipment that can effectively enhance the oil gathering effect, improve the oil collection efficiency, and have wave rejection effects.

Background technique

After the occurrence of offshore oil pollution incidents (especially when tankers collide), the oil floats on the sea surface and rapidly spreads to form an oil film, which can be migrated and transformed through diffusion, evaporation, dissolution, emulsification, photodegradation, biodegradation and absorption, etc. . The oil can adhere to the gills of the fish, suffocate the fish, inhibit the spawning and hatching of waterfowl, destroy the impermeability of their feathers, and reduce the quality of aquatic products. The formation of oil film can hinder the reoxygenation of water bodies, affect the growth of marine plankton, and destroy the ecological balance of the ocean. In addition, it can also damage the seashore scenery and affect the aesthetic value of the seashore. Oil pollution prevention and control, in addition to controlling pollution sources and preventing accidents, can be handled through oil booms, absorbent materials, and oil dispersants.

At present, there are two general forms of oil pollution treatment methods: one is to leave a gap on the side of the front of the oil recovery vessel. Allow the oil to flow directly into the vessel for collection. When using this method to clean up oil stains, since the oil stains are driven by the water waves when the ship moves forward, the oil stains will spread to both sides, resulting in incomplete and slow cleaning. The other is to use a brush cleaner collection method consisting of a float, a motor, a drum shell, a transmission shaft, a hub, a brush holder, bristles, a brush cleaner and an oil sump. When using this method to clean up greasy dirt, because greasy dirt has very strong cohesive force, the greasy dirt on the brush cleaner must be removed in a short working time, so that the decontamination speed is very low. Therefore, it is of practical significance to design a device that can quickly accumulate oil pollution and reduce the impact of waves on oil pollution treatment.
