Description
Technical field
This utility model belongs to boats and ships and causes atmosphere polluting controling technology field, specifically a kind of Novel ankle
Oceangoing ship exhaust gas scrubber.
Background technology
Sea transport, as a kind of very important means of transportation, occupies of crucial importance in international freight transport
Status.According to statistics, whole world sea goods trade aggregate tonnage has risen to 2009 from the 4000000000 of nineteen ninety tons
8,000,000,000 tons of year, it is contemplated that be up to 160-240 hundred million tons to the year two thousand twenty.Owing to transport by sea boats and ships are the most equal
Diesel engine is used to contain a certain amount of (mass fraction about 2.5%) as in power set, its heavy oil used
Elemental sulfur, this results in Marine Diesel Engine's Harmful Exhaust Emission containing substantial amounts of oxysulfide, to atmospheric environment
Cause certain pollution.Showing according to International Maritime Organization's statistical data in 2012, the whole world is with diesel engine as power
Boats and ships every year to the oxysulfide of airborne release more than 8,500,000 tons.Owing to the boats and ships in the whole world more than 70% are
Navigating by water in the range of about 400 kilometers of water front off sea, boats and ships sulfur oxide contamination has had a strong impact on coastal
The atmospheric environment in area.
At present, the requirement that International Maritime Organization, concerned countries and area control about boats and ships sulfur oxides emissions
More and more stricter.As " empty in MARPOL pact supplemental provisions VI, European Union's decree, CARB regulation and Hong Kong
Gas contamination control (ocean ship) (lay day use fuel) regulations ", all fuel oil sulfur content is carried out
Detailed and strict regulation.Wherein, the fuel oil sulfur content limit value in sulphur emissions control zone is in January, 2015
Within 1st, rise and be updated to 0.10% (m/m).
One of effective way controlling the discharge of boat diesel engine waste gas sulphur oxide is to install waste gas for boats and ships to wash
Wash device.Currently, commercialization marine exhaust wash mill mainly has open type, enclosed, hybrid three kinds of desulfurization
Mode.The basic functional principle of device is: sprayed into by alkaline detergent solution in scrubber so that it is inverse with waste gas
Stream contact, the basic component in alkaline detergent solution reacts with the oxysulfide generation acid-base neutralization in flue gas, from
And by the SO in waste gasxAbsorb and remove.Open type desulfurization system be utilize natural sea-water as alkaline detergent solution,
Sea water after washing after treatment can direct discharge into sea.Enclosed desulphurization system is to use NaOH fresh water solution
As alkaline detergent solution, it circulates work in systems.
The advantage of open type desulfurization system is only need to use natural sea-water, and operating cost is low, good economy performance.But
The desulfurized effect of this system depends greatly on the basicity of sea water, the pH value of the scrub raffinate of its discharge
Relatively low, need a large amount of sea water to be diluted, therefore, the water consumption of this system is big, consumes substantial amounts of ship
Oceangoing ship electric energy.The feature of enclosed desulphurization system is that desulfurized effect is unrelated with seawer quality, and system is the most overboard arranged
Put wash water.But this system need to consume substantial amounts of fresh water, run the time shorter, it is only applicable to boats and ships in short-term
The situation such as reach port.It is reported,The wet desulphurization device of the up-to-date release of company has contemplated that in enclosed pattern
Lower employing natural sea-water substitutes fresh water, reduces boats and ships fresh water usage amount, but this system fails effectively to solve fortune
The problem that the row time is short.
