example

[0054] A 300,000-ton oil tanker is equipped with 1 main engine, 3 auxiliary engines, and 1 oil-fired boiler, with a total power of about 30MW. The ratio of sulfur to carbon is less than 4.3 required by IMO, and the amount of inert gas supply can meet various working conditions such as loading and unloading of the ship, and the application effect is very good.

[0055] The embodiment of the present invention also provides an oil tanker equipped with the above-mentioned integrated device for exhaust gas desulfurization and inert gas supply, the engine exhaust gas inlet at the bottom of the inner tower is connected to the ship engine, and the boiler exhaust gas inlet at the bottom of the outer tower It is connected to the oil-fired boiler, and the boiler exhaust gas discharge pipeline is connected to the oil tank of the oil tanker.

[0056] Oil tankers are currently a mainstream ship type in the shipping market, and the inert gas system is an essential system for oil tankers, and...

Abstract

The invention provides a waste gas desulfurization and inert gas supply integrated device. The device comprises: a washing tower which is of a double-layer tower structure with an inner layer and an outer layer and comprises an inner tower and an outer tower, wherein an engine waste gas inlet is formed in the bottom of the inner tower and used for being connected with a ship engine, and an engine waste gas exhaust port is formed in the top of the inner tower, a boiler waste gas inlet is formed in the bottom of the outer tower and used for being connected with an oil burning boiler, and a boiler waste gas exhaust port is formed in the top of the outer tower and connected with a boiler waste gas exhaust pipeline; a spraying layer arranged in the inner tower, connected with a seawater pump and used for spraying seawater into engine waste gas; and a liquid collecting plate arranged in the inner tower, positioned below the spraying layer, and used for collecting the sprayed seawater and guiding the collected seawater into the outer tower.

Description

technical field [0001] The invention relates to the field of ship exhaust gas treatment, in particular to an integrated device for exhaust gas desulfurization and inert gas supply from an oil tanker. Background technique [0002] According to the requirements of the amendments to the Regulations for the Prevention of Air Pollution from Ships in Annex VI of the MARPOL 73 / 78 Convention adopted by the International Maritime Organization (IMO), the sulfur oxides and nitrogen oxides in the exhaust gas of ships must be treated up to the standard before they can be released. emission. [0003] For sulfur oxides, from January 1, 2020, the sulfur content of fuel oil used by ocean-going ships in global seas shall not exceed 0.5%. For fuel oil with a sulfur content exceeding 0.5%, a ship exhaust gas desulfurization system must be installed. For the exhaust gas desulfurization system of ships, the seawater washing method is generally used at present. As the core equipment of the exhau...
