Description

A kind of apparatus for treating ship ballast water

Technical field

The utility model relates to a kind of apparatus for treating ship ballast water, specifically, is a kind of device that carrys out effective Treatment of Ships'Ballast Water by dielectric barrier discharge reaction unit.

Background technology

When ship in ballast, in order to keep certain draft to be unlikely to topple, a certain amount of seawater will be drawn into the bilge to strengthen capacity of anti-storm in the time setting sail, during to loading, water be emitted again, this part sea claims that water is called ballast water for ship.

Water ballast is the important measures that ensure navigation safety, but it injects and discharge process is unavoidably carried a large amount of microorganisms.The marine organisms of carrying in ballast water for ship are mainly that those are very little and can enter the species of ballast for cruising bilge suction and ballast pump, mainly comprise: bacterium, virus, algae, protobiont, mollusk and fish etc.The whole world approximately has 80% transportation of cargo to complete by sea, and the transportation of cargo approximately having every year according to estimates completes by sea, approximately has the water ballast more than 10,000,000,000 tons to shift in the whole world every year according to estimates.In average every cubic metre of water ballast, there are 1.1 hundred million of planktons, the biology carrying in the water ballast that has confirmed to shift with ship global every day has 7000 kinds at least, the highlyest in every liter of water ballast contain 110,000 Micro Algaes, the dinoflagellate packing of surviving in a ballast tank approximately has 300,000,000, and oneself the 500 kinds of living species of having an appointment are emerging by the discharge of ballast water for ship so far.The infringement of ballast water for ship to ocean environment, is confirmed as one of four large threats of harm ocean by Global Environment Facility's tissue.

2004, International Maritime Organizaton (IMO) has passed through " ballast water for ship and sediment monitoring and management international convention ", be intended to reach international consistent, " preventing, reduce and finally eliminate the propagation of unwanted aquatic organism and pathogenic agent by control and management ballast for cruising water and sediment ".Discharge of ballast water may be upset the eubiosis, in order to tackle the threat to global environment causing thus, needs configuration to obtain the treatment system of IMO accreditation.According to the requirement of pact, if the new ship building up after 1 day January in 2009 must be installed special treatment facility; New ships all from 2012 all should be installed ballast water treatment system, and all existing ship should be equipped with technique device before the end of the year 2016.

At present, the treatment process of ballast water for ship mainly can be divided into two large classes, physical method and chemical process, common physical method has ultraviolet irradiation, ultrasonic method, electronic impulse and plasma pulse method etc., the common comparison in equipment complexity of these methods, and treatment effect is general, as ultraviolet irradiation, need the ultraviolet device of special generation, and ultra-violet sterilization method is higher to the requirement of water quality, in the time there is the material of larger particles, can affect treatment effect.And conventional chemical process ubiquity equipment impetuousness, long reaction time, processing speed is slow, need to carry a large amount of chemical substances, has secondary pollution problems.

Dielectric barrier discharge is named again silent discharge, is to be that 50 hertz of ac high voltages to megahertz level start by frequency, inserts a kind of geseous discharge of dielectric at discharge space.The low-temperature plasma of discharge generation, acts on the difficult for biological degradation pollutent in processed waste water, has the features such as treatment effect is good, non-secondary pollution.And dielectric barrier discharge has evenly, disperse and stable feature, the electron energy producing in dielectric barrier discharge process is far above corona discharge, the mean electron energy value of spark discharge, can fully make organic molecule, water molecules, oxygen molecule produces ionization, thereby inspire the particle that many activity are higher, C-C key and unsaturated link(age) in these active substances and high-energy electron bombardment pollution substance thereof, there is the series reaction such as scission of link and open loop, make macromole toxic substance become small molecules safe material, and even its removal the most at last, make waste water innoxious.Therefore, dielectric barrier discharge plasma processing water technology is with a wide range of applications.Although more existing dielectric barrier discharge technology is applied to the research of water treatment, but it is in gas, to produce dielectric barrier discharge that traditional sucrose barrier discharge plasma is processed the method for waste water, the plasma gas producing is passed into and in water, is carried out sewage disposal by mass transfer process, have that mass-transfer efficiency is low, short life material effectively mass transfer, cost high, the problem such as can not process continuously, and fail to be applied on boats and ships.Therefore develop a kind ofly for ballast for cruising water treatment, mass-transfer efficiency is high, pollutant removing efficiency is high, cost is low, can processed continuously dielectric barrier discharge water technology and install significant.
