Apparatus with sea marine organism pollution preventing function

Abstract

The invention discloses a device with the function of preventing marine creatures from dirt fouling. The interior of a filtering net of a sea water filter is provided with two ultrasonic oscillatory plates, sound production surfaces of which respectively face an inlet pipe and an outlet pipe of the sea water filter; and the interior of a sea chest also can be provided with the ultrasonic oscillatory plates directly above 25-35cm of vertical distances of a grating plate; the sound production surfaces of the ultrasonic oscillatory plates face the grating plate. The ultrasonic oscillatory platesare fixed on a cover plate of the sea water filter and a crest slab of the sea chest by a positioning rod and a connection pipe; the connection pipe leads out a power cord connected with an ultrasonic signal generator. The device can effectively hold up sea creature, cleans the sea water filter and the grating plate of the sea chest, and prevents the filtering net of the sea water filter and the grating plate of the sea chest from being blocked and the attachment of other sea creatures, thus achieving the purpose of effectively preventing marine creatures from dirt fouling.

Description

technical field [0001] The invention relates to a protection device for preventing seawater system pollution, in particular to a protection device for preventing marine organisms from fouling the seawater system. Background technique [0002] Seawater pipelines and seawater cooling systems of ships, offshore platforms, coastal power plants and coastal chemical plants are subject to double hazards of seawater corrosion and marine biofouling. Marine fouling organisms or marine attached organisms are animals, plants and microorganisms that grow on the bottom of ships and on the surface of offshore facilities; various hazards caused by their attachment to facilities are collectively referred to as marine biofouling. The attachment and growth of marine organisms in seawater pipes and cooling systems will reduce the effective diameter of seawater cooling pipes and heat exchanger condensing pipes, reduce seawater flow, and reduce cooling efficiency; once the attached organisms in t...

AI Technical Summary

Problems solved by technology

However, there are obvious deficiencies in the above methods: the mechanical method is quite labor-intensive and has little effect, and it is not easy to clean up at any time; the electrolysis method has limited practical effects due to the limited number of ions generated; the injection of chemical agents is not only expensive, but also requires a lot of investment. At the same time, it will also pollute the marine environment; toxic anti-corrosion protective paint will quickly fail under the immersion and erosion of seawater

More importantly, none of the above methods can specifically solve the problem of clogging of seawater filter screens and seabed door grilles and the adhesion of marine organisms
