Ship tail gas high-efficiency desulfurization device and using method thereof

Abstract

The invention discloses a ship tail gas high-efficiency desulfurization device and a using method thereof, belonging to the technical field of ship desulfurization. The ship tail gas high-efficiency desulfurization device comprises a primary desulfurization cylinder, a ship tail gas inlet pipe and an extraction pipe, the ship tail gas inlet pipe is arranged in the middle of one side wall of the primary desulfurization cylinder; the bottom end of the ship tail gas inlet pipe is connected with a gas outlet pipe; the extraction pipe is connected with the bottom end of the side wall of the primary desulfurization cylinder; and the using method of the ship tail gas high-efficiency desulfurization device comprises the following specific using steps: S1, wet primary desulfurization; S2, drying secondary desulfurization; and S3, discharging of desulfurized tail gas; the tail gas can be directly outputted to a desulfurizing liquid at the bottom of the inner cavity of the primary desulfurization cylinder through the arrangement of the gas outlet pipe so as to directly contact the desulfurizing liquid and perform desulfurizing; desulfurization powder is sprayed out through the spraying action of a spraying pipe and a spraying head, so that desulfurization is directly carried out on the desulfurization powder and the ship tail gas, and the secondary desulfurization is more thorough in desulfurization.

Description

technical field [0001] The invention relates to the technical field of ship desulfurization, in particular to a high-efficiency desulfurization device for ship tail gas and a use method thereof. Background technique [0002] In the world's cargo transportation, ocean transportation occupies a large proportion. Ocean cargo transportation has the characteristics of large traffic capacity, large transportation volume, low freight, strong adaptability to goods, low speed, and high risk. At present, more than two-thirds of the total volume of international trade, and 90% of my country's total import and export goods are transported by sea. [0003] With the rapid increase in the number of transport ships, the pollution and harm caused by the pollutants discharged by ships to the atmospheric environment and marine environment are also becoming more and more serious. The tail gas emitted by marine diesel engine combustion is mainly sulfur dioxide SO2 and nitrogen oxide NO2. Accor...
