Problems solved by technology
However, the use of low-sulfur oil will cause problems such as poor lubrication of the ship's power system, modification of the fuel supply system, and increased operating costs.
For alternative fuels, there are still many problems in the application of the mainstream fuel LNG: weak battery life, large equipment storage space, strict storage environment temperature requirements, etc.
Although the above-mentioned device has a certain desulfurization effect, in actual use, the removal effect on sulfide in the flue gas is still limited, so the application of the device is limited.

Embodiment 1
[0109]In order to verify the desulfurization effect of the exhaust gas desulfurization device provided by the present invention, a desulfurization module is used as an example to test. The desulfurization reagent adopts calcium hydroxide with a particle size of 3 to 5 mm. Connect the device, start the heat tracing system and the fan device, and after the temperature in the desulfurization component reaches the temperature required for the desulfurization reaction, the waste gas is introduced to carry out the desulfurization reaction.
[0110] The size parameters and operating parameters of the exhaust gas desulfurization device are shown in Table 1.

Abstract
The invention belongs to the technical field of desulfurization and in particular relates to a waste gas desulfurization device based on axial absorption and diffusion, a waste gas desulfurization method and a control system with the waste gas desulfurization device. Two desulfurization beds are arranged in parallel, the cavity between the two desulfurization beds is communicated with a gas inletof a desulfurization module, and together with arrangement of the position of a gas outlet, a waste gas is capable of passing through the desulfurization module in an annular flow turbulent mode, thewaste gas sufficiently contacts a desulfurization reagent, and the purpose of improving the desulfurization efficiency is achieved; a plurality of desulfurization modules are serially connected and used, so that the desulfurization efficiency can be further improved, and efficient removal of sulfides, PMs (Particulate Matters) and other impurities in waste gases is finally achieved.
Description
technical field [0001] The invention belongs to the technical field of desulfurization, and in particular relates to an exhaust gas desulfurization device based on axial absorption and diffusion, an exhaust gas desulfurization method and a control system for the exhaust gas desulfurization device. Background technique [0002] Ships are important means of ocean transportation. At present, most ship power plants use heavy oil with high sulfur content, and the SO produced x It is one of the important pollutants that form acid rain, and has caused great harm to the ecological environment and human health of port cities. The International Maritime Organization (IMO) established an Emission Control Area (ECA), and stipulated in Annex VI of the Convention MARPOL73 / 78: From January 1, 2020, on a global scale, the sulfur content of any fuel used for ship power shall not exceed 0.5% m / m. At the same time, in 2015, the Ministry of Transport of my country established ship sulfur emis...
