The invention belongs to the field of tail gas treatment, and particularly relates to a device for removing particulate matters in ship tail gas. The device comprises a shell and a tail gas treatmentunit arranged in the shell, the two ends of the shell are connected with a gas inlet pipe and a gas outlet pipe correspondingly, wherein the tail gas treatment unit comprises a bypass pipe, a filler pipe and an adjusting valve, the gas inlet pipe, the bypass pipe and the gas outlet pipe form a first tail gas passage, the gas inlet pipe, the filler pipe and the gas outlet pipe form a second tail gas passage, and the adjusting valve is arranged on the bypass pipe to be used for adjusting the amount of tail gas entering the first tail gas passage and the second tail gas passage in the gas inlet pipe according to engine back pressure and / or discharged tail gas smoke intensity. The device for removing the particulate matters in the ship tail gas has the following characteristics that the adjusting valve adjusts the flow of the tail gas entering a filler section, the emission reduction effect can be flexibly controlled, and the service life of a filler is prolonged.
Description
technical field [0001] The invention belongs to the field of tail gas treatment, and in particular relates to a device for removing particulate matter in ship tail gas. Background technique [0002] my country has become the largest shipping country with the largest number of ships and gross tonnage, and the pollution caused by ships cannot be ignored. Ships mainly use diesel oil or even heavy oil as fuel, and the exhaust exhaust contains a large amount of pollutants, mainly NOx, particulate matter and SO 2 Mainly. These pollutants will cause environmental hazards such as air quality degradation, greenhouse effect, acid rain and ozone layer depletion and seriously endanger human health. [0003] In order to reduce the air pollution caused by ships, the International Maritime Organization IMO formulated the MARPOL73 / 78 Convention Annex VI "Rules for the Prevention of Air Pollution Caused by Ships". and measurement methods (China's first and second stages)" (GB15097-2016). ...
