Description
Technical field
The utility model relates to ship's fitting, relates in particular to the improvement of ballast water treatment sterilising plant.
Background technology
2004, International Maritime Organizaton (IMO) passed through " control and management ballast water for ship and settling international convention ", is intended to reach international unanimity, solved jointly that the harmful water organic-biological transmits the problem of being brought in the water ballast between each area.
Discharge of ballast water may be upset the eubiosis, help harmful organism worldwide to propagate diffusion, in order to tackle the threat that causes thus to global environment, world many countries competitively drops into a large amount of manpower and materials and develops ship ballast water treatment system, wherein especially with Norway, the system of Canada and Japan and other countries research and development is comparatively advanced, its technical scheme mostly is greatly carries out chloridized and cavitation process to seawater, special cavitation process device produces the implosion frequency greater than more than the 100KHz, interior up to 1000bar to burstpressures, destroy the organic-biological in the seawater, and deoxidation treatment prevents aquatic organism regeneration.Because the enormous amount of water ballast, the boats and ships that have are up to several kilotons, handle a large amount of water ballasts at short notice, effectively kill in the water unwanted aquatic organism and be not easy, especially some aquatic organism has anti-chlorination ability, and chloridized and cavitation process can not thoroughly be killed unwanted aquatic organism in the water sometimes.
The utility model content
At the prior art above shortcomings, the purpose of this utility model is that a kind of ballast water for ship high-voltage pulse electric field sterilization device will be provided, its can wide spectrum, effectively kill the unwanted aquatic organism in the seawater, reach regulation and the requirement of International Maritime Organizaton, prevent unwanted aquatic organism dispersal by man diffusion about the ballast for cruising water treatment.
In order to solve the problems of the technologies described above, the scheme of the utility model technical solution problem is: the ballast water for ship high-voltage pulse electric field sterilization device, comprise high electric field pulse generating unit that is installed on the hull and the water pipe that is communicated with ballast tank, the some of described water pipe is the circuitous shape of bending, and the square section of this water pipe is rectangular, and be fixed with the plate electrode of being close to water pipe and being separated from each other respectively in the relative both sides of described water pipe outside surface, described plate electrode is electrically connected with the output terminal of described high electric field pulse generating unit, and the water pipe between the described plate electrode is made by high voltage withstanding pottery.
After adopting such scheme, because the cross-sectional area of water pipe is a rectangle, and the relative both sides of rectangular water tubes outside surface are fixed with the electrode of being close to water pipe respectively, and the plate electrode of water pipe both sides is electrically connected with the output terminal of high electric field pulse generating unit and forms the loop, thereby the seawater in the rectangular water tubes is in the radiation of the formed pulsed electric field of high electric field pulse, when the strength of electric field between the plate electrode during more than or equal to 20KV/CM, unwanted aquatic organism in the seawater in seconds will be killed, and the seawater that enters or discharge ballast tank is reached and meets the standard and the requirement of International Maritime Organizaton (IMO).Because the square section of water pipe is a rectangle, the plate electrode of water pipe both sides is in parastate, and two interelectrode strength of electric field are more even, and utilization rate of electrical is higher; Because rectangular water tubes is the circuitous shape of bending, increased the stroke of marine stream, prolonged the time that seawater is detained in rectangular water tubes, promptly increased the time of pulsed electric field radiation seawater, this plays a part crucial and effect to the aquatic organism of killing in the seawater, because rectangular water tubes is made by high voltage withstanding pottery, water pipe its insulating property under the pulsed electric field radiation keep stable, can be not breakdown, avoid having an accident.
The high electric field pulse generating unit is high voltage withstanding insulated conductor with the lead that is connected between the plate electrode, and the discontiguous one side of plate electrode and rectangular water tubes is enclosed with high voltage withstanding insulating material, avoids high-tension bus-bar and electrode to pass through atmospherical discharges.
The water pipe that plate electrode is installed is the part of the water inlet pipe of ballast tank of ship, seawater enters before the ballast tank aquatic organism and has been reached the pulsed electric field radiation of several seconds even longer time and cause death, and the seawater that enters ballast tank meets and reach the requirement and the standard of International Maritime Organizaton (IMO).
The water pipe that plate electrode is installed is the part of the water shoot of ballast tank of ship, in the seawater discharge process, the pulsed electric field radiation that aquatic organism is reached several seconds even longer time causes death, and the water ballast that flows out boats and ships meets and reach the requirement and the standard of International Maritime Organizaton (IMO).
The pulsed electric field radiation sterilization techniques is mature technology, the microbial cell film produces the perforation that can not repair or breaks in the seawater under the highfield effect, make histocyte impaired, cause bacteria inactivation rate, thereby surrounding environment and personnel there are not any chemical pollution and influence, this technology is widely used in the food antiseptic field already, food through radiation sterilization does not need to add any sanitas, and the anticorrosion quality guaranteed period of food be better than the food that adopts Chemical Preservative to guarantee the quality far away, be in theory or all be ripe on the equipment configuration so the pulsed electric field radiation sterilization techniques is applied to the ballast for cruising water treatment, feasible, effectively, safety.
The effect of pulsed electric field radiation sterilization is relatively good, and not only fast in sterilization speed, aspects such as killing rate height are better than chlorination water treatment and cavitation process, and the aquatic organism of antagonism chloridized has very high killing rate.Also much lower on volume that installs facility and cost in addition than special cavitation apparatus.
