Technical field
The present invention relates to being applied to the impact of water hammer pulsation wave system of ballast for cruising water process, belong to a kind of ballast water sterilization
Decontaminating apparatuss.
Background technology
Ship ensures vessel stability and navigation safety always using ballast water for a long time.Ballast water is for ship, special
The safety of unloaded ship it is critical that.Most ship all adjusts drinking water using ballast water, changes trim, adjusts
Section stability, or keep suitable stress.Install that place is different additional due to ballast water, ballast water can be fresh water, river sea mixing water
Or sea water.Algae, Mollusca, Fish and plant etc. can be contained in ballast water.The pressure that global ship carries every year according to estimates
Carry water about hundred million tons of 30-50, and ship is daily because the aquatic organism entrained by ballast water just has 7000 to 10000 kinds.Research table
Bright various bacteria, plant and animal can survive in ballast water in different forms.Caused sea is changed by ballast water for ship dress
Foreign biotic intrusion problem all brings increasingly severe threat to the marine eco-environment and sustainable development.From current ballast
In water process mode, there are marine replacing ballast water law, filtration, chemical treatment method, heating, electronic impulse and plasma arteries and veins
Punching, UV treatment, sonicated, magnetic field process, deoxidation treatment, biotechnology and antifouling coating etc. more than 10 are planted method and are answered
With or research among.What research adopted at present has multiple single method such as machinery, physics and chemistry, but is applied to
All have some limitations on ship, treatment effect is undesirable.For example, due to existing, penetration power is weaker to ask disinfection by ultraviolet light
Topic, is only capable of processing relatively thin water layer, and the colourity by ballast water, turbidity, Organic substance and the isoparametric restriction of open-minded class.Conventional ship
Ship ballast water sterilization be adopt have multiple single method such as machinery, physics and chemistry, but be applied to all deposit on ship
In certain limitation, treatment effect is undesirable.The cavitation erosion process of ultrasound wave also can cause water tank wall surface or structural damage,
Bring a series of problem to the application in ballast water field for the ultrasound wave.Recent researches find: under certain condition, pulsation

The fatigue damage hit valve outlet and cause, is close to one layer of rubber sheet gasket above valve seat, adopts between valve seat and rubber sheet gasket
Leakerna glue bonding.And corresponding water hammer ripple frequency and pressure amplitude can be obtained by adjusting the weight of valve seat.
By such scheme, the steel ball weight in spring non-return valve and initial tension of spring also should be adjustable, with mutual of dash valve
Join.Obtain optimal water hammer ripple frequency and pressure amplitude.
The principle of the present invention is: the current transmission from one meridian to another centrifugal pump in ballast tank provides certain flow velocity and flow to reach waterpower rotation
Stream separator, is separated granule larger for proportion by centrifugal action with liquid, reaches process chamber, flows through spring non-return valve and punching
Hit valve, when flow velocity reaches certain value, the pressure differential before and after valve seat forces dash valve to be closed, and produces hydraulic shock in the loop,
Impact forces be enough to make spring non-return valve open, and its positive dilatation wave is applied in the first energy storage canister, causes pulsation, treat it
Positive dilatation wave is exhausted when being converted into negative diffusion ripple, and dash valve automatically opens up, and recirculated water comes back to ballast tank, completes once
Circulation, is back and forth carried out.By the switch of hydraulic ram dash valve, ballast water treatment system causes impact of water hammer ripple, pipeline pressure
Power assumes the periodic pressure fluctuation of large amplitude, using the Hydrodynamic cavitation effect in pulsation system, the ballast water in ballast tank is entered
Row circulation sterilization.
Beneficial effect: the impact of water hammer pulsation wave system being applied to ballast for cruising water process of the present invention, by hydraulic ram
Spring non-return valve and the switch of dash valve, cause impact of water hammer ripple in systems, and loine pressure assumes large amplitude and periodically presses
Power is pulsed, and when pressure surge is transformed into negative (low-pressure) in system it may occur that Hydrodynamic cavitation effect, produces substantial amounts of gas
Bubble, greatly improves the efficiency processing ballast water, the effect of energy storage tank is the fluctuation pressure amplitude of control system, and ripple frequency is then
It is that decision is mutually matched by spring non-return valve and dash valve；This device more other ballast water sterilization processing method has cost
The features such as low, device is simple, the cavitation effect being caused using continuous water hammer, thus reach significant disinfection treatment effect.
