Background technology
Development along with shipping industry, ships quantity increases sharply, the biotic intrusion that causes because of the ballast water for ship discharging also becomes a global problem thereupon, the annual financial loss that therefore causes of the U.S. is up to 1,500 hundred million dollars, and the loss of China is also up to 57,400,000,000 yuan, more fearful is that some eco-catastrophe is irreversible.International Maritime Organizaton attaches great importance to this, has proposed stricter ballast water treatment standard---and " ballast water for ship and sediment monitoring and management international convention ", and require all ships before 2017, all new ballast water treatment plant will be installed.Yet traditional single method for disinfection can not reach requirement.According to the statistics of Lloyd's Register of Shipping, by in August, 2010, have in the world 24 equipment and obtained the initial and final approval that IMO organizes, China starts late, and only has 3 complete equipments to obtain the approval of IMO, and still also there is drawback in existing technology:
For example, (its ultimate principle is to utilize the strong ionization discharge method to carry out the research of water ballast, adopt strong electric field ionization oxygen, water molecules, make that H2O, O2 ionize, dissociation ionization and charge exchange reaction, be processed into oh soln at molecular level, again its is added in water ballast main delivery pipe), and all there are the power consumption height in the designs such as seawater electrolysis and neutralization optimizations, bacteriocidal substance can corrode the drawback of hull.And look like " extra large shield " ZG-I Ballast Water Treatment System, although do not have the danger of corroding hull etc. system, ignored the secondary pollution that draining causes, and the possibility of the processing cost rising that causes is with in dispensing.
Application number is in 200920076897.0 the patent document, to disclose a kind of ultraviolet catalyzed ballast water for ship treatment combination reactor, has comprised ultraviolet lamp and photocatalyst in its reaction member; The patent No. is: in the patent document of United States Patent 12/931,408, disclosed is the treatment process that a kind of filtration and ultraviolet combine.Although related to combined type ballast water processing or device in these open reports, treatment effect has much room for improvement.
Summary of the invention
The object of the present invention is to provide a kind of effectively processing ballast and save time again and the combined type ballast water treatment plant of energy-conserving and environment-protective.
The object of the present invention is achieved like this: comprise film filter, sterilization tube, water ballast is entering sterilization tube through after the film filter, the water ballast that goes out sterilization tube enters Ballast Tank, the inside of described sterilization tube arranges quartz burner, the inwall of sterilization tube is coated with titanium deoxid film, be furnished with the ozone entrance on the sterilization tube, in sterilization tube, add ozone by the ozone entrance.
The present invention can also comprise:
1, the front end at sterilization tube arranges Venturi tube.
2, comprise two or more sterilization tubes, each sterilization tube is arranged in parallel, and each sterilization tube front end all arranges Venturi tube, all is furnished with the ozone entrance on each sterilization tube, arranges water ballast is evenly distributed to the splitter of each sterilization tube behind film filter.
3, flocculation tank is set before film filter.
The invention provides a kind of effectively processing ballast and save time again and the equipment of the novel compound efficient processing ballast of energy-conserving and environment-protective, this equipment utilization the membrane filtration technique in the ballast water processing, ozone be combined treatment technology and oh soln inactivation technology with ultraviolet catalyzed titanium dioxide, water ballast is carried out the processing of " trinity ".
Mainly comprise three parts: (1) filtration unit, (2) inactivating device, (3) supporting accessory structure and device.The first, filtration unit cooperates with the ultraviolet catalyzed sterilizing unit, and the filtration fraction of this device adopts membrane filtration, and the film filter floor space is little, and processing speed is high, and maintenance cost is low, and operation is convenient.The second, the combination of jet mixing apparatus and ultraviolet catalyzed device.The venturi arrangement that this device adopts can produce cavatition.Except mixing effect, can also produce environment and the hydroxyl radical free radical of localized hyperthermia's high pressure, assisting sterilisation has shortened sterilizing time.It is to produce the minimum fluidic device of power consumption in the equipment of cavitation effect, has so just reduced the jet energy consumption.The 3rd, ozone adopts tube-separating type in conjunction with the sterilizing unit that ultraviolet catalyzed titanium dioxide produces hydroxyl, only puts a fluorescent tube in each sterilization tube, then makes sterilization tube in parallel.Compare with existing ultraviolet sterilization apparatus, it can take full advantage of quartz burner (360 °), and resistance is little in the water.The oxidizing potential of hydroxyl is only second to fluorine, can moment kill microorganisms, and before water flows out sterilization duct, disappear, do not have secondary pollution, processing speed is high, ozone and ultraviolet catalyzed are united the synergy of use greater than the effect of the two single use sterilization simultaneously.
Water ballast pumps into film filter by the water ballast water pump, remove the microorganism more than 50 microns, the Venturi tube of water ballast after the filtration before part flow arrangement enters each sterilizing unit, water ballast through the Venturi tube cavatition enters ozone-ultraviolet line catalytically bactericidal process device, in the catalytically bactericidal process device, uviolizing titanium dioxide produces hydroxyl radical free radical, utilizes hydroxyl radical free radical to decompose microorganism, germicidal action is also played in the simultaneously intervention of ozone, and sterilization water ballast up to standard enters water ballast tank.
