Description
Technical field
The invention belongs to the ship ballast water treatment device field, particularly a kind of filtration, the ultrasonic cruising ballast water treatment process of ultraviolet and equipment.
Background technology
The threat that tellurian ocean environment faces, roughly can be reduced four big classifications: sea life are to the intrusion of other Marine ecosystems; The pollution of the sea that originates from land; Destroy to the overfishing of oceanic resources and to the physical property of sea life habitat.Wherein boats and ships have been considered to cause the generation of sea life to the intrusion of other Marine ecosystems, and reason promptly is sea life that contain in the ballast water for ship and the sea life that are attached to hull.Ballast water for ship is to cause the main approach that propagate in the sea life strange land between geographical sexual isolation water body.The trade in commodities of the world more than 80% is through ship, and annual nearly 30 to the 5000000000 tons of water ballasts in the whole world flow at each seashore through boats and ships.Annual also have a large amount of water ballasts to flow within inside, various countries and each department.For modern transportation, water ballast is essential, and it can guarantee the safety and the efficient operation of boats and ships, and the balance that guarantees laden vessel not is with stable.Yet it also gives ecotope, and economy and human health have caused threat.2004, " ballast water for ship with settling control with manage international convention " that the 45th session of IMO maritime environment protection protective committee (MEPC) proposes outside the Shanghai Communications University can on pass, become mandatory international convention.The main contents of this pact are exactly the transfer that control contains the water ballast and the residue of dangerous hydrobiont and pathogenic agent; Requirements of convention: during navigation; Boats and ships should be at the deep-sea, open waters and carry out ballast water exchange away from the seashore place as far as possible; Need at least 200 nautical miles on nearest land and the depth of water at least more than the 200m, therefore must on boats and ships, install additional safety, efficiently, fast, ship ballast water treatment system cheaply.
In the improvement of the problem of ballast water for ship harmful organism invasion at present, can remove with the method for physical filtering than macro-organism, but unicellular organism and small protozoon can't effectively be removed because individuality is too little.The scientific worker has carried out the research work of a large amount of control ballast water for ship harmful organism invasions: as change the method for water ballast at the deep-sea; It is the feasible measure that effectively reduces adventive invasion, but exist consumed energy too high with problems such as operation, working time be long; Heating ballast water law, the Nitzschia closterium minutissima in the water ballast just caused death after under 38 ℃ of conditions of water temperature 2 hours, exist the treatment time long, energy consumption is too high, the thermal stresses of formation will influence insoluble problems such as ship security.
Summary of the invention
Goal of the invention: the purpose of this invention is to provide treatment process the efficient low and cost problem of higher of a kind of ship ballast water treatment method, and the mikrobe in the seawater that can effectively suppress to handle regenerates in ballast tank to solve the existing ship water ballast.
Technical scheme: for solving the problems of the technologies described above; The invention provides a kind of filtration, the ultrasonic cruising ballast water treatment process of ultraviolet and equipment, it comprises electromagnetic valve, water pump, pressure transmitter, under meter, strainer, ultraviolet excess sonication unit, system, electromagnetic valve and pipeline.Water gets into strainer via water pump, gets into ultraviolet excess sonication unit then and carries out bioinactivation, at last discharging.The collaborative sterilization of ultraviolet excess acoustic device can have better effect, and UW destroys the resist of mikrobe, uv-radiation destroy microorganisms DNA, RNA, and UW also has certain cleanup action to ultraviolet lamp tube simultaneously.
As optimization, the ultrasonic comprehensive treating process of ultraviolet unit inwall adopts mirror polish to handle.
As optimization, ultrasonic generating unit has adopted the low frequency ultrasound generating unit, and its frequency is 15～75KHz.
As optimization, what filtering unit adopted is the millipore filter of automatic washing, and filtering accuracy is adjustable according to practical situation, and scope is 10～100 μ m.
Said strainer and the unitary shell of ultraviolet excess sonication all can adopt in stainless steel or titanium steel alloy material be sealed in it.
Said ultraviolet excess sonication unit can be designed to right cylinder with shell, shapes such as rectangular parallelepiped through inner fluorescent tube quantity and processing requirements.
The unitary water-in of said ultraviolet excess sonication can be arranged on the device top, also can be arranged on the device below.
Said ultraviolet generation device can be selected low pressure high performance type amalgam vapour lamp for use, middle pressure high performance type amalgam vapour lamp, high pressure ground output type amalgam vapour lamp.
Said uv lamp fluorescent tube can adopt natural quartz or synthetic quartz.
The inner mercury of said uv lamp adopts disrupter and outside to separate, and this disrupter is designed to thin film, its material can for plastics perhaps other not with the material of mercury generation chemical reaction.
Said system is an operating in a key, and this system is full intellectualized, only needs the button of any link of crawl, and equipment can move automatically, does not have any subsequent operations, even emergency situation takes place, system also can remove voluntarily.Like this system's may command ultraviolet device individual curing, the ultrasonic associated treatment of Vltrasonic device individual curing and ultraviolet.
Beneficial effect: the present invention can efficiently kill tiny organism in the boats and ships water, and the low safety of energy consumption is high, and running maintenance is easy, can pass through the Automatic Control Unit operating in a key, also can select erecting stage flexibly according to practical situation.
