Description
Technical field
The utility model is related to a kind of ballast water for ship ultraviolet sterilization devices.
Background technology
Ballast water is the important guarantee of marine operation safety, and foreign-going ship is injected during navigation and discharge ballast water
When, easily cause the domain over strait of unwanted aquatic organism and pathogen to be propagated.Ballast water is discharged without control to marine ecology, public health
Cause serious harm.It is estimated that up to 4500 kinds of the biology that the whole world is carried by ballast water for ship daily, gives Port State environment
Marine environment brings serious threat.
In order to cope with the biotic intrusion that ballast water for ship is brought, International Maritime Organization（Abbreviation IMO）It formulates《Ballast for cruising
Water and sediment monitoring and management contract》, according to the regulation of pact, the processing of ballast water refers to killing and removing in ballast water
Microorganism.In numerous ballast water processings, filtering/ultraviolet light mode is the ballast water treatment side being most widely used at present
Formula, feature have compact-sized, small, control simply, do not use chemical agent, do not generate chemical substance, safer, more ring
It protects；But there is also some problems, for example when ultra violet lamp, the easy fouling of quartz socket tube outer wall can reduce ultraviolet transmittance,
Influence UV treatment effect.To solve the problems, such as this, current common solution is to increase additional cleaning device to quartz
Casing is cleaned, and common cleaning program can be divided into following several classes：
（1）Mechanical cleaning mode,UsingThe method that cleaning ring is scraped in quartz socket tube outer wall removes dirt.In quartz socket tube
A cleaning disk is arranged in axially vertical plane, is cleaned on the position for corresponding to each casing on disk and is provided with through hole, each through hole
It is middle to fix a soft cleaning ring, so that each casing is passed through a cleaning ring.Meanwhile motor need through threaded screw rod and
Bearing passesDrivingDisk is cleaned, cleaning disk is made to carry out gliding motility along the axial direction of quartz socket tube.In taxiing procedures, cleaning
Ring scrapes off dirt from quartz socket tube outer wall surface, achievees the purpose that cannula cleaning.That there are problems is as follows for this cleaning way：To chamber
The concentricity of body, casing and cleaning disk is more demanding, and the deviation of processing and installation can cause motor rotation blockage or even casing collapse；
In the process of running, lead screw will bear cleaning disk weight, be likely to result in lead screw bending, can equally cause motor stifled when serious
Turn in addition casing collapse；In addition, lead screw can cause electricity in thread surface dirt deposits after a certain period of time in work when serious
Machine stall or even casing collapse.
（2）Physical cleaning mode removes dirt using the principle of ultrasonic cleaning.Implementation method is as follows：Portion in the cavity
Arrange that ultrasonic transducer, energy converter are more than the ultrasonic wave of 20kHz, the microbubble in liquid can under the action of sound wave to
Vibration is kept, the absorption of dirt and sleeve surface is destroyed, causes the fatigue rupture of dirt and refuted to reach cannula cleaning
Purpose.Since sound wave is along straightline propagation, sound wave is difficult to reach shielded region, such as the quartz in face of ultrasonic transducer
Sleeve surface is easy to clean clean, but ultrasonic wave can not continuously penetrate quartz socket tube, ultraviolet lamp fluorescent tube, fluorescent tube airspace,
Mercury vapour interval in ultraviolet lamp fluorescent tube,（4 layers of quartz glass and 3 layers of gas）, back to the quartz socket tube table of ultrasonic transducer
Face can not just be cleaned.In order to realize 360 ° of cleanings of quartz socket tube, it is necessary to more in multiple angles arrangement of quartz socket tube
Ultrasonic transducer.There are the following problems for this cleaning way：Not only increase system cost, volume and power consumption, can also influence purple
The effect of outside line inactivation.Because ultraviolet light is also along straightline propagation, ultrasonic transducer can equally hinder ultraviolet light propagation and
Superposition, excessive blocks the dead angle for being also possible to will produce ultraviolet radioactive.System also needs to increase the quantity or defeated of ultraviolet lamp
Go out power, further increases system cost, volume and power consumption.In addition, the ultrasonic wave that ultrasonic transducer generates generates altogether with water
It shakes, this resonant frequency belongs to frequency of sound wave, and this noise can influence the normal work of crewman.
（3）Chemical cleaning mode, is added chemical agent, and the method that redox reaction occurs removes dirt.By to pressure
It carries and injects acid solution in water treatment system, the carbonate components of incrustation scale are decomposed, to take out stains.Although the method is effective,
But there are still some problems：First in the process of running, acid solution can not be injected when system processing ballast water, can not carried out
On-line cleaning；Secondly cleaning system needs to increase drug reservoir, mixing vessel, heater and water pump etc., increases ballast water treatment
Volume, cost and the complexity of device；Cleaning needs to use chemical agent and heater again, increase the use of system at
This.
Above-mentioned several cleaning programs both increase system complexity, reduce system reliability and maintainability, increase simultaneously
Big system cost.
Utility model content
Its purpose of the utility model is that a kind of ballast water for ship ultraviolet sterilization device, can prevent dirt adsorption sleeve
Pipe surface prevents foulant sticks sleeve surface, prevents dirt deposition in sleeve surface, to reach self-cleaning effect.
Adopt the technical scheme that achieve the above object, a kind of ballast water for ship ultraviolet sterilization device, containing casing,
Ultraviolet lamp, cavity, bobbin seal fixing device, uitraviolet intensity sensor, flow switch and temperature switch, the casing are
It is that the middle pressure containing 185nm wave bands is purple that outer wall, which has the quartz glass sleeve of super-hydrophobic nano-silica coating, ultraviolet lamp,
Outer lamp or low pressure ultraviolet lamp, cavity axial direction are parallel with the axial direction of quartz socket tube.
Advantageous effect
The utility model has the following advantages compared with prior art.
The utility model has the advantages that having self-cleaning effect, increases cleaning system without additional, reduce system complex
Degree improves system reliability, reduces use cost.
