Description
Technical Field
The utility model belongs to the technical field of the ocean environmental protection technique and specifically relates to a boats and ships tail gas washing tower that possesses direct vent function is related to.
Background
Exhaust gas from ships usually contains harmful gases and smoke, and if the exhaust gas is not properly treated and discharged directly, it pollutes the atmosphere. The international maritime organization IMO stipulates that from 1 month and 1 day 2015, the emission standard of the sulfur oxides of ships in north america, the baltic sea, the north sea and the caribbean area (ECA area) is reduced from the original standard value to 0.1%; in all European sea areas except ECA, the upper limit of the emission standard of the ship sulfur oxides is reduced to 0.5 percent, and is further reduced to 0.1 percent by 2020; by 2020, a new upper limit on sulfur oxide emissions of 0.5% will be in force worldwide. China requires that the upper limit of the emission standard of the sulfur oxides of ships in inland rivers and coastal waters of Hainan island is reduced to 0.1%. On the other hand, the international maritime organization IMO stipulates that ships are within 3 seas near seaports and do not allow discharge of the washing water containing chemicals. Ship operators generally adopt the following three schemes to promote the emission of ships to meet the above-mentioned regulatory requirements: 1. low-sulfur fuel oil is directly used as fuel; 2, using high-sulfur fuel oil as fuel, and additionally installing a washing desulfurization device; 3. and the sulfur oxide emission is reduced by using LNG as fuel and the like. By combining the higher price difference between low-sulfur fuel oil and high-sulfur fuel oil in the market, most ship operators select to additionally install a washing desulfurization device, use the high-sulfur fuel oil as a main fuel and simultaneously prepare a small amount of low-sulfur fuel oil. When the ship sails in a sea area where the washing water is allowed to be discharged, high-sulfur fuel oil is used as a main fuel, and the discharged tail gas is discharged into the atmosphere after being washed and desulfurized by a washing tower. When the ship runs in a sea area such as a port where the discharge of wash water is not allowed, the fuel is switched from high-sulfur fuel oil to low-sulfur fuel oil, and the low-sulfur tail gas after combustion is directly discharged to the atmosphere without desulfurization and washing.
Because the flue gas generated by a ship engine has a high temperature of about 300 ℃, the scheme of the U-shaped washing tower with more built-in fillers in the industry at present does not support that the high-temperature flue gas is directly discharged into the atmosphere after passing through the washing tower due to the limitation of the structure and the material of the U-shaped washing tower; a three-way valve and a bypass flue are required to be arranged in front of the air inlet section of the U-shaped washing tower and are used for directly discharging flue gas; the scheme needs to occupy larger hull space, has overlarge back pressure and has larger potential safety hazard to the original ship power system.
The other I-type washing tower scheme in the industry has two functions of washing desulfurization and high-temperature direct discharge, and an empty tower spraying scheme with a filler-free structure is adopted, so that more than 4 spraying layers are generally required to meet the desulfurization requirement, each layer of spraying needs to have a certain distance, and the spray mist parameters have more severe requirements; the scheme not only requires the washing tower to have higher height, but also has higher requirements on the corrosion resistance of the material of the whole tower, and simultaneously requires a detergent spray head with higher precision; this will greatly increase the cost of installing the scrubber.
