Abstract

The invention relates to the technical field of scrubbers and in particular relates to a marine exhaust gas desulfurization purification scrubber. The scrubber comprises a tank body, a scrubbing device and a liquid storage tank, wherein the scrubbing device and the liquid storage tank are arranged inside the tank body; the liquid storage tank is arranged at the lower part of the scrubbing device;the tank body comprises an inlet, an exhaust pipe, a drainage pipe and an outlet; the scrubbing device refers to at least two groups of baffle plates fixed into a whole by virtue of wide positioning blocks; a desulfurization catalyst plate is a desulfurization catalyst layer formed by uniformly spraying a desulfurization catalyst on the surface of a metal plate; the baffle plates are at least twogroups of liquid drop separators which are detachably connected into a whole by virtue of first positioning blocks; and the liquid drop separators are composed of at least two separation channels in fixed connection by virtue of second positioning blocks. The invention solves the problem in the prior art that a marine exhaust gas scrubber is poor in desulfurization effect, and provides the scrubber with advantages of being excellent in desulfurization effect, excellent in liquid-gas separation effect and small in pollution of discharged liquids.

Description

technical field [0001] The invention relates to the technical field of scrubbers, in particular to a scrubber for marine exhaust gas desulfurization and purification. Background technique [0002] Desulfurization has always been a difficult problem in the control of ship exhaust gas pollution. Annex VI of MARPOL 73 / 78, one of the international maritime environmental conventions, and the Implementation Plan for Ship Emission Control Areas in the Pearl River Delta, Yangtze River Delta, and Bohai Rim (Beijing-Tianjin-Hebei) Waters issued by the Ministry of Transport of China in 2015, all have regulations on ship exhaust. The upper limit of the sulfur limit must meet the strict requirements of different standards of 0.1% and 0.5%. [0003] At present, ship exhaust gas scrubbing and desulfurization systems (EGCS) are mainly divided into two categories: dry scrubbing and desulfurization systems and wet scrubbing and desulfurization systems. Due to the special requirements of shi...
