Ship flue gas purification device

Abstract

The invention discloses a ship flue gas purification device. The device comprises a first treatment chamber, a combustion chamber, a second treatment chamber and a flue gas pipe, wherein the first treatment chamber is communicated with a marine main engine through a flue gas pipe, the first treatment chamber is communicated with the second treatment chamber through a flue gas pipe, the first treatment chamber is communicated with the combustion chamber, an adsorption mechanism is arranged on the first treatment chamber, a combustion mechanism is arranged in the combustion chamber, and a purification mechanism is arranged in the second treatment chamber; the ship flue gas purification device, by means of the adsorption mechanism, not only can filter fixed particles in ship waste gas, but also can adsorb liquid components like oil mist in the ship waste gas, and through an incineration mechanism, activated carbon which is adsorbed to be saturated is sufficiently combusted, the limited space on a ship can be saved, harmful gas and oil mist adsorbed in the activated carbon can be thoroughly removed, and the subsequent treatment cost is saved.

Description

technical field [0001] The invention relates to the field of ships, in particular to a ship flue gas purification device for a 70,000-ton wood chip ship. Background technique [0002] Ocean-going ships such as 70,000-ton wood chip ships generally use large low-speed two-stroke diesel engines as the main propulsion device. Due to the solid particles in the fuel and insufficient combustion of the fuel, there will be a large amount of harmful substances in the exhaust gas, such as oil mist, solid particles, Carbon monoxide, nitrogen oxides and sulfur oxides, among which the purification treatment technology for nitrogen oxides and sulfur oxides has been perfected, but the treatment of oil mist, solid particles and carbon monoxide is still not perfect; [0003] Therefore it is necessary to provide a new ship flue gas purification device to solve the above problems. Contents of the invention [0004] The object of the present invention is to overcome the defects in the prior a...
