Dust removal, desulfurization and decarbonization integrated device for ship tail gas and ship

Abstract

The embodiment of the invention provides a dust removal, desulfurization and decarburization integrated device for ship tail gas and a ship, and belongs to the technical field of ships. The integrated device comprises a comprehensive absorption tower and a carbon dioxide and separation liquid circulating system, wherein the comprehensive absorption tower is used for carrying out desulfurization, dust removal and decarburization treatment on the ship tail gas, carbon dioxide is separated out from a decarburized rich solution, a barren solution is separated, and the separation liquid circulating system is used for utilizing the rich solution and the barren solution. The ship tail gas is subjected to desulfurization, dust removal, decarburization, absorption and desorption treatment, the decarburization efficiency can reach 90% or above, the desulfurization efficiency can reach 98% or above, the dust removal efficiency can reach 80% or above, the total weight of comprehensive absorption equipment does not exceed 2% of the weight of an empty ship, the device is suitable for ships of various tonnages and ships of various fuels, the equipment composition is simple, the installation and use are convenient, and the influence on existing standardized ship design is small.

Description

technical field [0001] This specification relates to the technical field of ships, and specifically relates to an integrated device for dust removal, desulfurization and decarbonization of ship tail gas and a ship. Background technique [0002] The shipping industry has become an important means of transportation for international goods. Under the background of global warming, ship exhaust emissions will inevitably face increasingly stringent regulatory requirements. For example, as the industry gradually adapts to the current 2020 sulfur limit promulgated by the International Maritime Organization The International Maritime Organization plans to introduce new rules to reduce carbon emissions from ship exhaust. Therefore, for the shipping industry, a "zero-carbon future" is not only a goal, but also brings new challenges to ship design and exhaust gas treatment technology when implementing carbon emission reduction.

Problems solved by technology

[0009] However, these ship decarbonization schemes still require multiple devices, with complex structures and high construction costs, and the efficiency of carbon dioxide absorption still needs to be improved

[0010] In addition, in view of the complicated fuel sources of ships, there are various types of ship fuels, such as heavy oil, low sulfur oil, diesel, LNG (Liquefied Natural Gas, liquefied natural gas), methanol, etc., and even some
