Greatly, the features such as diffusivity is big, the duration is long.It is shown according to International Maritime Organization (IMO) statistical data in 2014, ship discharge
SOx, NOx account for about the 13% and 15% of Global emissions total amount respectively.The statistics display of Chinese environmental protection portion motor vehicle blowdown monitoring center,
National ship SO2 discharge capacitys account for about the 8.4% of national total emission volumn within 2013, and NOx discharge accounts for 11.3%, by Pollution From Ships shadow
Ring maximum is port city, secondly rivers bank city.Ship machine exhaust pollution has become after tail gas pollution of motor-driven vehicle, industry
After enterprise's exhaust emission, the third-largest atmosphere pollution source in China has caused the strong interest of the whole society.
Chinese transportation Department of Transportation proposes《Ship and port pollution prevention special campaigns embodiment (2015-2020
Year)》, explicitly point out, to the year two thousand twenty, Pearl River Delta, the Yangtze River Delta, Circum-Bohai Sea (Jing-jin-ji region) waters ship oxysulfide, nitrogen oxides,
Particulate matter declined 65%, 20%, 30% respectively compared with 2015.Therefore, the ship machine exhaust pollution control policy in current China
It is broadly divided into three aspects:First, realize the control of SO2 by strictly controlling the fuel oil that ship uses;Second is that it is marked by discharging
Standard limits the discharge of CO, HC, NOx and PM etc.;Third, by actively promoting the use of bank electricity, the tail during ship reaches port is reduced
Gas discharges, and makes at " green harbour ".Marine exhaust is administered extremely urgent.
Research and development currently for the treatment technology of ship tail gas are still at an early stage.206397567 U of CN disclose ship
Oceangoing ship exhaust gas denitration system, Benitration reactor mainly include Urea Evaporation room, mixer and reative cell, which is equipped with
Urea liquid spray gun, the mixer connect the Urea Evaporation room and the reative cell, and exhaust gas is de- into this through the exhaust gas denitration pipeline
Behind the Urea Evaporation room of nitre reactor, mix with urea and enter after the reative cell carries out denitration through the mixer and discharge.CN
104326604 B disclose it is a kind of based on the marine exhaust desulfurization washing water treatment technology and its processing system of alkaline process is received, mainly
It is to introduce marine exhaust desulfurization washings to neutralize oxidation integral pool, air is blasted by sulphite into pond by Aeration fan
Sulfate is oxidized to, the pH value of the marine exhaust desulfurization washings added in sodium hydroxide solution adjusting neutralization oxidation integral pool reaches
To discharge standard, and using aeration disturbance neutralize it is quenched.Common marine exhaust treatment technology has SCR, EGR, washer
Etc. technologies, these technical principles it is different, respectively have its scope of application and feature, advantage and disadvantage.Therefore, still lacking one kind in the market can
Meet emission request, take up little area, is efficient, safeguarding at ship denitrating flue gas that is simple, adapting to marine special natural environment waterborne
Reason system.
