Marine fuel after combustion, can produce containing oxysulfide (hereinafter SOX), nitrogen oxides (hereinafter NOX)
Deng material, these materials can be discharged in air with the form of waste gas.And SOXIn SO2, form acid rain after oxidation, to environment meeting
Cause huge threat.The data provided to International Maritime Organization (IMO) according to Norway shows, boats and ships year discharge SOXReach 6,340,000
Ton, accounts for the 4% of world's total emission volumn.Therefore, marine exhaust discharges the pollution caused to environment and has arrived the ground that can not be ignored
Step.International Maritime Organization (IMO) " " 73/78 anti-pollution convention " (MARPOL pact) supplemental provisions VI require: i.e. from 2012,
The sulphur content of fuel oil of the foreign-going ship exercised in high sea have to be lower than 3.5%(m/m), would fall to 0.5%(m/m to the year two thousand twenty),
And this scheme completes feasibility and examines and will carry out earlier than 2018.Supplemental provisions VI the 14th article specify that any boats and ships use fuel oil
Sulfur content is not to be exceeded 4.5%(m/m), and worldwide mean content of sulfur for the residual fuel oil on ship should be made
Monitoring.
The boats and ships year discharge sulfur dioxide 58.8 ten thousand tons of Chinese Port alongside accounts for the 8.4% of whole nation total emission volumn, boats and ships pair
Directly polluting of port city accounts for about 20%；Yard craft nitrogen oxide emission 27.8 ten thousand tons accounts for whole nation total emission volumn
11.3%.Yard craft disposal of pollutants has become the third-largest atmospheric pollution after tail gas pollution of motor-driven vehicle, industrial undertaking's discharge and has come
Source.
Department of Transportation is in December in 2015 issuing and implementation on the 4th: " Pearl River Delta, the Yangtze River Delta, Circum-Bohai Sea (Jing-jin-ji region) waters ship
Oceangoing ship emission control district embodiment "；Chinese environmental protection portion formulates " engine of boat and ship tailpipe emission limit value and measuring method
(Chinese first and second stage) " and consulted on to whole society's second time disclosure with on 06 8th, 2015.If new standard is formally issued
Cloth is implemented, and will be that first Chinese issues boats and ships Air Pollutant Emission control national standard.
Existing flue gas desulfunzation device uses wet desulphurization, will spray in waste gas, with waste gas with the form of spraying by alkali liquor
Mixing, through chemical reaction by SO in waste gasX、NOXCatch and enter in liquid phase, reach the purpose purified.But the general high temperature of waste gas,
Alkali liquor sprays into meeting partial gasification in waste gas, together discharges with waste gas, it is possible to cause secondary pollution.

Speed is reacted through asymmetric nano thin-film porous ceramic fiber hollow pipe, pre-absorption agent, and asymmetric nano thin-film porous pottery
Porcelain fiber hollow pipe can work more than at a temperature of 500 ° of C, it is contemplated that service life was more than 10 years.
The most described ceramic-film tube aperture is 50 ~ 200nm.
In the total measurement (volume) of the most described ceramic-film tube and waste gas, the ratio containing S amount is 0.3 ~ 0.4m3:1kg/h。
Additionally provide the application in purifying marine exhaust of a kind of ceramic membrane air washer peculiar to vessel further, by described ship
It is arranged in boats and ships exhaust gases passes with ceramic membrane air washer, exhaust gases passes cross section and the upper and lower cross-sections match of air washer；To inhale
Receiving agent to be injected by feed liquor end socket, absorbent flows out from going out fluid-tight head through ceramic-film tube, subsequently into heat exchanger cooling Posterior circle
Enter ceramic membrane air washer, absorb SOX、NOXAfter, enter regenerating unit regeneration, recycle.
The most described absorbent is sodium hydroxide solution, and concentration is 13% ~ 15%.
The most described absorbent flow velocity in ceramic-film tube is 200 ~ 350m/h.
The heat that the most described heat exchanger absorbs heating system on ship.The temperature of waste gas is 150 ~ 300 DEG C,
Taken out of by absorbent through purifier rear portion heat, and absorbent is absorbing SOX、NOXAfter also can produce heat, will inhale
Receive agent after heat exchanger heat exchange, the heating system that the heat energy of this part is used on ship, the fuel of 3 ~ 8% can be saved.
Beneficial effect: compared with prior art, it is an advantage of the current invention that:
1) the waste gas produced efficiency of the water transportation such as boats and ships, ocean platform, operation carrier is purified high, removable 99.6%
SOX, the NO of 95%X；
2) modular device can effectively reduce the transformation of the carrier waterborne such as spot ship, ocean platform, install clean gas dress additional
The technical difficulty put；
3) ceramic membrane technology is not directly contacted with absorbent by the waste gas in flue, needed for optionally absorbing us again simultaneously
The harmful substance wanted and particulate matter；
4) energy recovery that absorbent can also will absorb, the heating system on ship, the energy of saving.
