Description
Technical field
The invention belongs to marine engineering equipment technical field, and in particular to be filtered to a kind of ship ballast water management system
The antiscaling method and device of device.
Background technology
During ocean vessel sailing, ballast is a kind of inevitable state.The strange land of ballast water, which loads and discharges to cause, to be had
Evil aquatic organism and the propagation of pathogen.To control the harm of ballast water for ship, International Maritime Organization (IMO) formulates《International ship
Ship ballast water and sediment monitoring and management contract》.At present, the mainstream technology of ship ballast water management system can be divided mainly into thing
Managing partition method (patent of invention 201280007040.8), irradiation method (patent of invention 200980147399.3), chemical method, (invention is special
Profit 201180068282.3, patent of invention 201310497967.0) and above-mentioned several method combination application (patent of invention
200580000930.6 patent of invention 201210139407.3).Wherein, filtering technique is spot ship Ballast Management system
Treatment technology (patent of invention 201110272181.X, patent of invention 201110387626.9, the patent of invention generally used
201180074175.1, patent of invention 201280007040.8), it is mainly used in filtering out biological or outstanding more than 50um in ballast water
Floating particles, laid the foundation for subsequent treatment.
The filter that Ballast Management system uses at this stage uses land technology more, there is that volume is big, backwash water
The problems such as more, back pressure height, blowdown difficulty, it is difficult to meet foreign-going ship installation, use and maintenance requirement.In order to solve above-mentioned ask
Topic, for vessel characteristics, develop labyrinth type filter screen (patent of invention 201310290075.3), the filter (invention of band blowdown axle
Patent 201310616720.0), prevent back pressure formed ballast water filtering device (patent of invention 201180074175.1), filtering
Device blowdown apparatus (201210508241.8) etc..With the popularization and application of ship ballast water management system on deep-sea vessels, close
The problem of some are new is emerged again in filter.Such as current filter is mainly backwashed using High-Pressure Water, but with making
With the extension of time, the effect of backwash is gradually reduced, and filter is frequently occluded；In addition, according to current ballast for cruising water pipe
Manage system operatio flow, generally using ballast when start management system, ballast water is handled, at the end of ballast, stop pipe
Manage system operation.After management system is out of service, accumulate a large amount of seawater, biology and still undischarged toward contact in filter
Dirt.Foreign-going ship is generally 1-3 months in the voyage schedule of big midocean.The above-mentioned seawater and dirt remained in filter, it will
Filter with inner surface, filter screen corrosion and scaling are caused, growth attachment of the residual biological on filter screen will directly result in filter net jam,
Have a strong impact on reusing for ship ballast water management system.But not yet have solve ship ballast water management system use at present
The correlation technique of filter deposit, blocking etc..

1) the step of double-filtration being carried out to ballast water：Ballast water first carries out by-pass filtration through coarse strainer, flows into fie screen and carries out
Secondary filtration；
2) the step of being backwashed to fie screen：Fie screen is backwashed using blowdown mouth and blowdown chamber；
3) the step of using sludge in sewage unit discharger；
Characterized in that, also include：
4) the step of Electromagnetic Treatment being carried out to the water in fie screen using variable-frequency electromagnetic processing unit：Change the arrangement side of hydrone
Formula, prevent fouling；
5) the step of sonicated being carried out to package unit using ultrasound unit：Remove on screen surface and equipment inner structure
Dirt；
6) processor for ultrasonic wave, after ballast terminates, isolated operation can be during ship's navigation to the filter screen knot of filter
Structure is effectively safeguarded, prevents the fouling of filter interior body structure surface and biological attachment；
7) ballast water treatment carries out Electromagnetic Treatment simultaneously, is ultrasonically treated after the completion of processing, and the former reduces the formation of dirt, the latter
Dirt is purged, the two collaboration, has the function that effective antifouling scale removal.
