Description

Ship propulsion using sodium and emissions reduction system for harmful gases {APPARATUS USING SODIUM FOR VESSEL PROPULSION AND REDUCTION OF HARMFUL SUBSTANCE IN EXHAUST GAS}

The present invention relates to a ship propulsion and exhaust gas reduction apparatus using sodium to produce hydrogen and alkaline water from a sodium cartridge, using hydrogen for ship propulsion, and alkaline water for the reduction of harmful emissions.

In general, ships are discharged into the air by harmlessly treating the exhaust gas generated during the use of engines and boilers.

As a background technology of the invention, for example, the exhaust gas purification method and apparatus of the patent document shown in Fig. 1 is a seawater supply means (1), electrolysis device (2), alkaline liquid supply line (3), acidic Exhaust gas, which includes a liquid supply line 4, a gas-liquid contact device 5, an exhaust gas blower 6, an exhaust gas inlet 7, an exhaust gas outlet 8, and a waste liquid detoxifying device 9 It is configured to reduce sulfur oxides in the air, as well as to treat nitric oxide or carbon dioxide and dust.

The electrolysis device 2 generates an alkaline liquid at the cathode through electrolysis of seawater. The produced alkaline liquid is injected inside the gas-liquid contact device 5 through the alkaline liquid supply line 3, and harmful gas (e.g., exhaust gas flowing from the exhaust gas inlet 7 to the exhaust gas outlet 8) (e.g., Attempts have been made to reduce NOx, SOx and CO2).

However, the device of the patent document injects a certain amount of power into the seawater (seawater electrolysis) to separate the seawater temporarily into acidic (Cl-) and alkali (OH-), and to contact the exhaust gas using alkali (OH-). In order to reduce the harmful substances in the exhaust gas, acidic liquids containing acidic (Cl-) components are also generated from the seawater, and a separate waste liquid harmless device (9) or wastewater capable of treating the acidic liquids thus produced is disposed. The disadvantage is that additional lines are required.

In addition, since the patent document cannot generate hydrogen that can be used for the propulsion of the ship, in order to generate and use hydrogen in the vessel to which the technology of the patent document is applied, it is necessary to provide more space for mounting a separate hydrogen plant. Have

On the other hand, there is an increasing demand for greenhouse gas reduction in the world.

As a result, major countries are holding a UN General Assembly of Climate Change (COP) to continue discussions on greenhouse gas reductions. In this regard, the International Maritime Organization (IMO) is in the process of regulating the ship's environment, and is preparing to regulate CO2 emissions. Accordingly, there is an increasing demand for the development of eco-friendly vessels that reduce CO 2 by reducing fossil fuel usage. Among them, research on hydrogen fueled vessels is underway, but there are some problems.

First, there are difficulties in the technology of storing, transporting and releasing hydrogen.

For example, hydrogen is contained in a hydrogen storage container having a hydrogen storage alloy, which varies depending on its type, but generates about 700 degrees of heat when adsorbed hydrogen and about 100 degrees below zero when hydrogen is released. In order to use the stored hydrogen, it is possible to discharge the hydrogen storage alloy together with the discharged hydrogen when it is discharged out of the hydrogen storage container to use the stored hydrogen, and a filter is used together to prevent this. This may cause problems such as damage to the filter of the hydrogen storage container.

In addition, there is a second method of producing only hydrogen directly from the ship, but requires another fuel and energy to directly produce hydrogen, or requires a dedicated space for the hydrogen plant to produce only hydrogen, space utilization is reduced, There is a need for a device that performs a complex and efficient function by supporting only a single function in terms of function.

In addition, in the case of sodium, the reaction with water can occur rapidly, and there is a lack of means for easily using sodium in the ship, there is a disadvantage that handling and use is very difficult.

In addition, thirdly, the gas-liquid contact device itself is difficult to use by directly laying it on the exhaust pipe. That is, since the acidic liquid and alkaline liquid which have been contacted with the exhaust gas fall down vertically of the gas-liquid contacting device, it is difficult to install the gas-liquid contacting device in a simple combination in the exhaust pipe.
