Abstract
The present invention discloses a system and a method for efficiently removing sulfur oxide in ship waste gas. The removal process is divided into three stages: a pre-treatment stage, bubbling and primary desulfurization stage, and a spraying and secondary desulfurization stage. The method comprises the following steps of: respectively introducing fresh sea water into a pre-spraying chamber, a desulfurization tower and an aeration tank through pipelines; firstly cooling the high-temperature waste gas, and removing part of sulfur oxides in the pre-spraying chamber; introducing the cooled waste gas into the desulfurization tower and uniformly spraying the cooled waste gas into a sea water bubbling zone through a gas distribution tube; introducing the waste gas into a spraying zone through an ascending passage of the desulfurization tower so as to carry out further removal of sulfur oxides; demisting the waste gas by a demister, and discharging the demisted waste gas into the atmosphere through a chimney; and restoring the water quality of desulfurized seawater by virtue of primary aeration in the desulfurization tower and secondary aeration in an aeration tank. Compared with a traditional seawater desulfurization technology, on the premise of not increasing the space occupancy rate of the seawater desulfurization system, the method solves the problem that the desulfurization efficiency is generally low when seawater desulfurization technology is applied in ships.
Description
Technical field
The invention belongs to marine exhaust pollution prevention technique field, be specifically related to a kind of system and method utilizing seawater to remove marine exhaust sulphur oxide.
Background technology
Along with the increase of volume of world trade, boats and ships are as important means of transport, and its transport capacity obtains in 21 century and develops fast, and current global tonnage has reached more than 85000 more than the boats and ships of 100t.But the pollution from exhaust emission brought because of shipbuilding industry development makes people worried, especially the pollution of oxysulfide.According to statistics, the annual emissions of global boats and ships oxysulfide reaches more than 900 ten thousand tons, accounts for 7% of World Sulfur emissions of oxides total amount, accounts for 60% of whole carrier sulfur oxides emissions.
The method of current reduction boats and ships sulfur oxide emission mainly contains two kinds: use low-sulphur fuel and carry out exhuast gas desulfurization.Low-sulphur fuel use cost is high, and uses this fuel need transform the fuel oil equipment of boats and ships, economically and technically sees that this method is not reduce the optimal selection of sulfur oxide emission.MARPOL pact supplemental provisions VI points out, boats and ships can use the waste gas cleaning system of the directive/guide accreditation worked out by IMO through competent authority.Based on the successful Application of sea water desulfuration technology on the land facilities such as thermal power plant, nearly more than ten years people start consideration and apply it on boats and ships.It is low that sea water desulfuration technology has operating cost, without solid waste, without the need to outstanding advantages such as any artificial chemical desulfurization agent.For the boats and ships navigated by water on ocean, seawater resources enrich, boats and ships can be gathered materials on the spot, the seawater after desulfurization treated up to standard after can flow back to ocean again, economize on resources, therefore sea water desulfuration technology has extraordinary application prospect in marine exhaust desulfurization.
Although sea water desulfuration technology has above-mentioned advantage, this technology is applied on boats and ships and is also faced with some technology barriers.Sea water desulfuration technology be applied in land facility as thermal power plant, oil plant etc. can reach more than 90% desulfuration efficiency.But being different from land facility, boats and ships are mobile pollution source, and whole desulphurization system all must be arranged on boats and ships.And the limited free space of boats and ships seriously limits the scale of desulphurization system, this means that seawater need absorb a large amount of oxysulfides within the very short time of staying.But seawater is extremely limited to the absorbability of oxysulfide at short notice, therefore sea water desulfuration technology is applied in desulfuration efficiency on boats and ships generally lower than 90%.
And be mostly spray and filler mode for the desulfurization method of sea water desulfuration technology at present.Although spray mode good economy performance, energy consumption is low, and structure is simple, and distribution of gas is uneven, there is edge effect, causes desulfuration efficiency lower.Be the spray tube bank that the desulfuration efficiency reaching more than 90% often need arrange more than 3 layers when boats and ships are applied, add system complexity and maintenance difficulty.Also need the multiple EGR of peripheral hardware to realize the circulated sprinkling of seawater, not only energy consumption is large, also takies boats and ships additional space simultaneously.Although and the control of filler mode is simple, gas-liquid contact is good, because resistance is comparatively large, easily produces wall flow phenomenon, cause desulfuration efficiency limited, and boats and ships additional space storage filler need be taken.Absorption and neutralization are integrated in bubbling pond by the bubbling desulfurization method that the Ecosilencer seawater desulfurization device of MES company invention adopts, reduce the area occupied of whole device, but because this desulfurization method same pond seawater realizes the cooling effect of high-temp waste gas and the absorption process of oxysulfide, cause gas-liquid mass transfer declines, sea water desulfuration efficiency is lower.
To sum up, on boats and ships, sea water desulfuration technology problems faced is applied at present mainly:
1) sea water desulfuration efficiency is general lower;
2) there is the problem that distribution of gas is uneven and device area occupied is larger in desulfurization method;
3) all there is the contradiction between system space occupancy in various degree and desulfuration efficiency in existing technical scheme.
If above problem can not get effective solution, then the application of sea water desulfuration technology on boats and ships will can not get promoting.And the boats and ships not installing Deuslfurizing system for sea water cannot arrive region boats and ships sulfur oxides emissions being had to strict restriction, seriously hinder the Trade Development between different country.Each marine site, the world can be freed in and out for making foreign-going ship, better realize the international trade of diversification, the method for efficient removal marine exhaust sulphur oxide under a kind of prerequisite not increasing Deuslfurizing system for sea water space occupancy rate of pluses and minuses proposition of the comprehensive above desulfurization method of the present invention.
