Description
Technical field
The present invention relates to environmental technology field, especially a kind of novel ship exhaust gas treating method and device.
Background technology
Atmospheric environment is the valuable resource that the mankind depend on for existence, and the destruction of atmospheric environment resource is a kind of irreversible process, recovers good atmosphere quality than the Air Pollution of taking measures fundamentally and pays more economic cost.Yet in the modern society, the damage ratio of atmosphere is more serious, traces it to its cause, and atmosphere pollution mainly contains several kinds of dust granules, carbon dioxide, sulfur dioxide or nitrogen oxide etc.
Boats and ships operation meeting needs a large amount of fuel, can produce a large amount of accessory substances during fuel combustion, like dust, carbon dioxide (CO
2), nitrogen oxide (NO
x) and sulfur dioxide (SO
2) wait pernicious gas.These noxious gas emissions can seriously influence human beings'health in atmosphere, also can hinder the growth of plant, thereby cause the severe contamination of earth environment.
Carbon dioxide is greenhouse gases, and scientist's prediction is because greenhouse effects; To the year two thousand fifty global temperatures with rising 2-4 degree centigrade, iceberg, polar region, north and south will be melted significantly, cause the sea level to be risen greatly; Some island countries and coastal cities will be flooded in water; Comprising several famous international big cities: New York, Shanghai, Tokyo and Sydney.
SO
2And NO
xBe the main atmosphere pollution that forms acid rain and acid mist, ecological environment and health are had significant damage.
Just because of as above reason, people have just had the technology of various control atmosphere pollution.
The technology of administering pollutant is to the difference of pollutant and difference.
The main method that particulate pollutant is administered is: to the particulate pollutant size, mainly contain 4 types of dry method, wet method, filtration and static, the most frequently used is exactly sack cleaner (filtration), cyclone dust collector (dry method), bubble dust collector (wet method) etc.Along with the raising that efficiency of dust collection is required, electrostatic precipitation is also progressively brought into use.
Owing to had a large amount of nitrogen oxide, oxysulfide in the atmosphere, atmosphere pollution just taken place, so produced contamination accident a piece by a piece.Scientist is to the character of this type oxide, and the technology that has proposed contaminated solution has absorption process, absorption method, condensation method, catforming, firing method, biological clarification, membrane separation process and dilution method.
Yet, regrettably, in the prior art, have all basically that equipment cost has high input, pollutant removing efficient is low, can not remove carbon nitrogen amounts of sulphur contaminants or the like shortcoming simultaneously.
