Technical field
The present invention relates to marine antifouling dyeing technique field, particularly the device of a kind of method for supplying oxygen of sea water desulfuration and enforcement the method.
Background technology
Present large-scale oceangoing vessel acts as a fuel mainly with poor residuum, and the average sulphur content of fuel oil is 2.7%, have up to 3.5% even 4.5%.It is reported that annual boats and ships discharging SOx reaches 6,340,000 tons, accounts for 4% of world's total emission volumn, the oxysulfide in its discharging flue gas has caused serious pollution to surrounding enviroment, thereby causes the attention of International Maritime Organizaton (IMO).Be to reduce the topsoil that the boats and ships sulfur oxides emissions causes, MARPL pact supplemental provisions VI amendment has been carried out strict restriction to oxysulfide (SOx) emission standard, and the discharge capacity of marine exhaust sulphur oxide is limited.For reaching the sulphur emissions index two kinds of control methods are arranged: the one, adopt low sulphur fuel oil, the 2nd, carry out the waste-gas desulfurization purification system.For large-scale oceangoing vessel, use low-sulfur fuel will increase fuel cost more than 1,000,000 dollars every year, and different areas require difference to the sulphur content of the used fuel oil of ship entry, and switching the different fuel oil of use sulphur content can be unstable because of the not good combustionproperty that causes of consistency.These factors have all promoted flue gas desulfurization purification system applying on boats and ships.
Consider the specific condition of boats and ships, be mainly reflected in: can utilize the less and high (O of oxygen level of little, relative coal-burning power plant, space discharge amount of exhaust gas
212%), do not allow bulk deposition consumptive material and by product etc.The sea water desulfuration technology is to utilize natural full sea water as the absorption agent of sulfur dioxide in flue gas, need not other any additives, raw material sources are convenient, do not produce any waste yet, meeting the marine diesel desulphurization system to requirements such as cost, stability, is a kind of desirable marine exhaust desulphurization control technology.And in the seawater desulfurizing process process, the aeration tank is independent structures and the critical process link in the seawater quality recovery system.Aeration system becomes vitriol with sulfite oxidation in the seawater, and drives away the CO in the seawater
2, the pH value of raising seawater realizes the purpose that seawater quality recovers.Yet the blower fan that aeration adopts and blast main equipment are complicated, structural volume is large, coefficient of oxygen utilization is low, working cost is high, the noise of gas blower is high, and the aeration tank floor space is large, causes seawater desulfurization device too huge.Owing to can utilize limited space on the boats and ships, strict to the installation dimension of equipment, this directly affects sea water desulfuration and uses in the marine exhaust discharging.Therefore, how dwindling or save the aeration tank is to determine that can sea water desulfuration be applied to the key issue of ship domain.
Summary of the invention
