Description
Technical field
It is to fulfil the United Nations for shipping " ship is big the present invention relates to a kind of ship tail gas cleaning method and ship and application
Gas pollution convention " (MARPOL pact supplemental provisions VI) and relevant laws and regulations and the invention made, belong to APollution prevention technology for ships and ocean work
Journey technical field.
Background technique
According to " the ship atmosphere pollution convention " of contracting party's signature, the United Nations IMO will be implemented entirely from the year two thousand twenty January 1
Ball ship limits sulphur and enables, specifically from the year two thousand twenty March 1, if global ship is fitted without equivalent tail gas washer up to standard
(EGC), just it is not allowed to carry the bunker oil that sulfur content is more than 0.5%.It is enabled due to using Low Sulfur Fuel Oil mode to execute limit sulphur merely,
There are low-sulfur oil price lattice are currently higher, it is at a specified future date may higher navigation cost lifting trend (low-sulfur oil refining process carbon emission is big
Width increase will be restricted by Paris climate agreement), shipping world is engaged in the ship for closing rule shipping using EGC scheme to Low Sulfur Fuel Oil is not had to
Oceangoing ship is expected higher and higher.However, the problem of existing EGC scheme ship, mainly has: 1, the ship of " open type " EGC is installed, using IMO
The classical technical solution of EGC directive/guide: sea only is discharged into natural sea-water (not adding artificial chemistry product) once washing；Especially
The wherein higher EGC of detersive efficiency can accomplish that total energy consumption is only the 1% of corresponding engine power, or even washer is embedded in
Muffler is without additionally occupying space on ship；" open type " EGC ship in most ocean shipping occasions, have cost-effectiveness,
The generally acknowledged advantage of atmospheric environment protection and marine eco-environment protection aspect, but locally forbid appointing at a small number of littoral seas and harbour
The occasion of what form washing water discharge can not be applied, therefore formation a small number of " bottlenecks " may block major part voyage EGC application very
To the situation for influencing normal/cruise；2, the ship for installing " enclosed " EGC, uses artificial alkaline chemical, the slag and effluent of generation
Must be stored on ship cannot be to ocean disposal, but " enclosed " washing system complexity occupy space on ship larger, cost and operation
With high costs, the cost of harbour handling caused by especially a large amount of basic materials and slag and effluent and land emission treatment is difficult to control
System reduces it therefore with respect to the cost and environment-friendly advantage of Low Sulfur Fuel Oil；3, the ship of " hybrid " EGC is installed, it is therefore an objective to
Allow and do not allow the sea area for discharging washing water that can apply, but " hybrid " EGC system is to be superimposed " to open in " enclosed " system
Formula " system, thus system is more complicated, cost and operating cost are higher, and the cost for as a result significantly losing opposite Low Sulfur Fuel Oil is imitated
Beneficial advantage.
Ship fulfils IMO limit sulphur and enables status, and MARPOL pact is fulfiled in a manner of keeping navigation cost benefit to shipping business
Demand with Paris climate agreement proposes challenge.
Summary of the invention
Present invention aims at overcome and arrange sea EGC scheme ship because of related international regulations using seawater once washing and lack
Number part regulation has differences and makes to close the shortcomings that rule tradding limit is restricted, and is ocean shipping and part river Hai Lianyun, mentions
Rule navigation can be closed in the sea area for allowing to discharge and forbid to discharge washing water for a kind of, and keeps once washing EGC technical costs
The tail gas cleaning method and ship of benefit advantage and application.
A kind of technical solution of ship tail gas cleaning method of the present invention includes the following steps:
A) engine of boat and ship tail gas is imported and uses washing water once washing motor exhaust, the once washing in washer
It is that washing water disposably passes through washer and the washing methods without circulation；B) motor exhaust by washer purification is discharged into
Atmosphere；C) when ship boat is through forbidding discharging the waters of washing water, the acid wash water switching of washer discharge is imported into ship storage
Water/ballast tank storage；D) chemical neutralization is carried out according to emission regulation demands to water storage/ballast tank storage acid wash water
