Abstract

The invention discloses a low-temperature sulfur and nitrate removal device for ship tail gas and a treatment method, wherein the device includes a rotary reactor, an ammonia water spray tower and an ammonia water storage tank, and the rotary reactor is provided with a cylindrical shell and a top cover and the bottom cover, the housing is provided with a honeycomb column, and the rotary reactor is provided with a partition, and the partition divides the sealed space between the honeycomb column and the top cover and bottom cover into the first space and the second space. and the third space. In this method, the collected ship exhaust gas is introduced into the first space, the second space and the third space through the pipeline, and after a sufficient reaction, it is discharged through the exhaust pipe through the induced draft fan. The invention can efficiently treat ship tail gas, simplifies the treatment process, improves the treatment efficiency, saves the space occupied by the device, reduces the energy consumption, and produces ammonia fertilizer as an additional product.

Description

technical field [0001] The invention relates to a tail gas treatment device, in particular to a ship tail gas low-temperature sulfur and nitric acid removal device and a treatment method. Background technique [0002] In recent years, with the continuous development of international and domestic shipping, SO in marine diesel engine exhaust 2 with NO X Increasing impacts on the environment and threats to human health. In particular, the diesel consumption of domestic ships accounts for about 15% of the diesel used in non-road transportation, and emits a large amount of SO 2 with NO X , is an important environmental protection object. According to the 2014 IMO statistics of the International Maritime Organization, the annual emission of SO from ship exhaust 2 with NO X They account for about 13% and 15% of total global emissions, respectively. In order to effectively control SO 2 Emissions, the 70th meeting of the Marine Environmental Protection Committee under the Int...
