Description
Technical Field
The invention relates to the field of ship tail gas treatment, in particular to a ship tail gas desulfurization and denitrification integrated device.
Background
According to the MARPOL convention, in the emission control region of the Polo sea, the North America and the Caribbean sea, the sulfur content of the ship fuel oil is not more than 0.1% after 1 month and 1 day of 2015; after 1/2020, the maximum sulfur content of marine fuel in other global sea areas than the emission control area must not exceed 0.5%.
Currently, there are three main effective measures for sulfur emission limitation in the industry:
one is the use of low sulfur oils. The use of low sulfur oil has less modification to ships and is the simplest countermeasure at present. However, since the price of low-sulfur oil is basically stabilized to about one time of that of heavy oil, the use of expensive low-sulfur oil will cause heavy fuel cost burden to shipowners. In addition, the use of heavy oils from low speed diesel engines (product depot supply) to long or total use of low sulfur oils also requires modification of engine (product depot supply) related systems. And because there is great difference in physical properties between the heavy oil that low sulfur oil and host computer (product storehouse purchase supply) used, cause the fuel easily to reveal the danger and aggravate the host computer wearing and tearing, will cause the harmful effects to the safe operation of boats and ships.
And the LNG fuel is adopted to replace fuel oil. However, the equipment and the associated systems are expensive, the cost of ship construction is expected to increase by about 3000 thousands of dollars, and the safety is always controversial. Meanwhile, port filling facilities are also generally imperfect worldwide. Natural gas is used as fuel power, and besides the investment cost is excessive, the natural gas is used as flammable and explosive hazardous gas and is transported in double-wall pipelines when the LNG exists in a gaseous state. The annular space between the double-walled pipes needs to be inerted or vented (product depot supply), and monitored in real time (product depot supply) for leaks. The density of LNG is less than half of that of heavy oil for ships, the LNG bunker has a much larger volume than the fuel bunker, and whether there is enough space to arrange a fuel tank with a large volume is also a problem to be considered. Moreover, LNG, as a fuel for ocean vessels (location review news), is still in the face of problems such as insufficient endurance.
Thirdly, ship desulfurization and denitrification equipment is additionally arranged. By adopting the mode, the shipowner does not need to modify the engine and the oil supply system, and can continue to use the cheap heavy oil matched with the performance of the host. The method avoids various ship operation risks caused by low-sulfur oil replacement, and huge modification cost required for using natural gas as fuel, and can save a large amount of fuel oil cost for shipowners. If the ship runs in the sulfur control and exhaust area all the year round, the cost can be recovered about one year, and the ship is safe and reliable without worries about.
Compared with the two previous solutions, the third solution is easier to solve than the two solutions, so that a low-cost, safe and reliable ship desulfurization and denitrification device is needed, and the problems of sulfur and nitrate discharge of ships can be effectively solved.
In addition, for the dust removal of the off-gas, charcoal or coke adsorption is generally used, and it is necessary to provide sufficient charcoal or coke for sufficient adsorption of the nitride or sulfide, but this also leads to an increase in cost, and therefore it is also desirable to reduce the use of charcoal or coke.
An effective solution to the problems in the related art has not been proposed yet.
