Abstract

The invention relates to a desulfurization chimney and a manufacturing and mounting method thereof. The desulfurization chimney comprises a chimney assembly and a desulfurization device arranged in the chimney assembly, the desulfurization device assembly is integrally arranged in the chimney assembly. The device arrangement is reasonable; the modularized design degree is high; and during ship desulfurization and installation, only the desulfurization chimney needs to serve as an independent unit to be hoisted onto a ship, and the pipeline connector of a desulfurization tower accessory is connected with the exhaust pipelines of a main engine and an auxiliary engine of an original ship to form a set of recyclable desulfurization system, so that the workload of dismounting or refitting the original ship is greatly reduced, the construction period is favorably shortened, and the refitting cost is saved. The manufacturing and mounting method is reasonable in process arrangement and convenient to operate, and device damage is not prone to occurring in the mounting process; good butt joint of the desulfurization chimney and an original ship structure can be guaranteed through positioningof the desulfurization tower and the desulfurization tower base, so the structural stability and the structural strength are high, and it is guaranteed that normal operation of the desulfurization tower is not affected.

Description

technical field

[0001] The invention relates to the technical field of ship desulfurization, in particular to a desulfurization chimney and a manufacturing and installing method thereof. Background technique

[0002] The International Maritime Organization (IMO) formally decided at the 70th session of the Marine Environment Protection Committee (MEPC70) that starting from January 1, 2020, ships sailing around the world can only use fuel oil with a sulfur content of no more than 0.5%. Meet this requirement to reduce sulfur dioxide (SOx) emissions in the exhaust.

[0003] SOx in ship exhaust gas is a pollutant formed after the combustion of sulfur in fuel oil, and it is difficult to achieve the purpose of SOx emission control through the technical transformation of fuel oil combustion equipment (such as diesel engines, boilers, etc.), only through fuel pre-treatment and exhaust gas post-treatment Or use alternative fuels to control to reduce SOX emissions.
