Description
Technical field
The present invention relates to be applied to the impact of water hammer pulsation wave system of ballast for cruising water process, belong to a kind of ballast water sterilized
Chlorination equipment.
Background technology
For a long time ship ensures always vessel stability and navigation safety using ballast water.Ballast water is special for ship
Be not 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.Place difference is installed additional due to ballast water, ballast water can be fresh water, river sea mixing water
Or seawater.Can be containing algae, mollusk, fish and plant etc. in ballast water.The pressure that according to estimates global ship is carried every year
Water about hundred million tons of 30-50 is carried, 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 be survived in different forms in ballast water.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 among research.What at present research was adopted has various single methods such as machinery, physics and chemistry, but is applied to
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 matter and the isoparametric restriction of open-minded class.Conventional ship
Ship ballast water sterilization be adopt have various single methods such as machinery, physics and chemistry, but be applied to be deposited on ship
In certain limitation, treatment effect is undesirable.The cavitation erosion process of ultrasonic wave can also cause water tank wall surface or structural damage,
A series of problem is brought to application of the ultrasonic wave in ballast water field.Recent researches find：Under certain condition, pulse
In the case of cavitation phenomenon positive influences it is ignored always, crumbling and fall with cavitation bubble when cavitation occurs, moment can discharge
Go out substantial amounts of energy, using the energy sterilized and disinfective action is realized, reach synergy, energy-conservation, the effect of consumption reduction.This is just ship
Ballast water sterilization process provides new approach.
