Description
Technical field
The present invention relates to a kind of marine exhaust residual-heat utilization technology, particularly a kind of boat diesel engine waste gas treatment and utilized device and method of work thereof.
Background technique
IMO (International Maritime Organization) data shows, the SO that boats and ships discharge every year
2reach 6,340,000 tons, account for 4% of world's discharge amount.Very important stage has been arrived in the pollution of atmosphere that boats and ships cause, and at some harbour, intensive place, straits, marine exhaust has become the primary pollution source of local pollution of atmosphere.In September, 1997, International Maritime Organization have passed MARRPOL pact (preventing boats and ships from polluting international convention) supplemental provisions VI, and these supplemental provisions came into force in China, to the SO in marine exhaust on August 23rd, 2006
2discharge made strict restriction.MPEC (ocean environment and protective committee) 58 meetings in 2011 have passed MARPOL pact supplemental provisions VI amendment, and the discharge of amendment to boats and ships atmospheric pollutant proposes further requirement.Amendment required from 1 day January in 2012, and the Sulpher content of global reduced fuel oil is reduced to 3.5% from present 4.5%; And feasibility assessment was made before 2018, if assessment is passed through, to the year two thousand twenty January 1, the Sulpher content of ball bunker fuel oil of will demanding perfection is reduced to 0.5%.For sulphur emissions control zone, from 1 day July in 2010, this region bunker fuel oil Sulpher content must not more than 1.0%; Must not more than 0.1% from 1 day January in 2015.
