Embodiment Construction

[0053] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0054] As a specific example, such as figure 1 As shown, an integrated treatment system for ship tail gas and ballast water according to the present invention includes an electrochemical seawater modification reactor, a ballast water treatment reactor and a tail gas purification scrubber. Specifically include: filter 1; oxidation deactivation component 2; subsequent discharge reduction component 3; pipeline 4; valve 5; anode cavity 6; diaphragm 7; cathode cavity 8; oxidation scrubber 9, alkaline absorption scrubber 10, hydrogen fuel A battery reactor 11 and a micro-nano bubble generating device 12 . The above-mentioned components are connected through the pipeline 4 as a gas path and a liquid path.

[0055] The strong oxidizing liquid flow is generated in the anode cavity 6, and is transported to the oxidation inactivation component 2 to oxidize an...

Abstract

The invention discloses a ship exhaust and ballast water integrated treatment system and belongs to the field of an environmental technology. The integrated treatment system comprises an electrochemical seawater modification reactor, a ballast water treatment reactor and an exhaust gas purifying scrubbing tower and is characterized in that the exhaust gas purifying scrubbing tower comprises a micro-nano-bubble generating device, an oxidizing scrubber and an alkaline absorbing scrubber. The basic principle of the system is that the electrochemical seawater modification reactor carries out electrolysis on seawater so that two liquid flows such as a strong oxidizing liquid flow and an alkaline liquid flow having different performances are formed. The strong oxidizing liquid flow can be used to deactivate microbes in ballast water and to oxidize ship exhaust. The alkaline liquid flow can be used to neutralize and absorb oxidized ship exhaust. H2 produced by the electrochemical seawater modification reactor is used for a hydrogen fuel cell so that H2 recovery and recycle are realized and explosion damage is prevented. The system provides a novel energy supply method for a ship with limited energy. The system realizes efficient treatment on ship exhaust and ballast water, has a small size and is conducive to use in the ship.

Description

technical field [0001] The invention relates to an integrated treatment system for ship tail gas and ballast water, which belongs to the field of environmental technology. Background technique [0002] More than 80% of the world's international trade is realized through ocean transportation. According to the data of the International Maritime Organization (IMO) as of December 2010, there are about 104,304 ships of more than 100 gross tons in operation around the world. With the continuous increase in the number of transport ships, the pollution and harm caused by the pollutants discharged by ships to the atmosphere and water bodies are also becoming more and more serious. [0003] At present, in order to save costs, marine diesel engines generally use low-quality (high sulfur content) heavy oil, so a large amount of pollutants are released, mainly nitrogen oxides (NO X ), sulfur oxides (SO X ), carbon oxides (CO X ) and fine particulate matter (PM 2.5 ) and other air pol...
