Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a ballast water-

The present invention relates to a marine equilibrium biological killing apparatus using a combustion gas, and more particularly, to a marine equilibrium biological killing apparatus using a combustion gas, The present invention relates to a ship ballast water damper using a combustion gas which kills the whole of the equilibrium water through water.

In general, ship ballast water is an essential factor to help safe navigation of vessels. As international transportation volume increases, the amount of ballast water used is increasing rapidly. However, this increase in ballast water usage has increased the inflow of non-living alien species in each country, causing enormous environmental damage and disturbance of ecosystem by alien species. At the end of 1980, Canada and Australia suffered damage to the ballast water and complained to IMO, resulting in the International Convention on Ballast Water in 2004. As a result, the shipbuilding equipments have been equipped with new equipments for shipbuilding equipments since 2009, and existing vessels will be fitted to all international marine transportation vessels from 2015 to 2017.

Currently, the ship ballast water treatment methods commonly used include ultraviolet sterilization, ozone sterilization, electrolysis, heat treatment, use of sodium hypochlorite, chlorine dioxide, chlorine treatment, steam supply, microbubble use, There are many advantages and disadvantages of each treatment method, and it is a mixed trend. We are doing research and development internationally to meet IMO standard. The most problematic approach is the corrosion of the ship itself and the complete destruction of the organisms in the ballast water. Also, the unit price of the equilibrium water treatment apparatus has become a problem. Ozone disinfection and electrolysis are expensive and hull corrosion is concerned. In the case of chemical treatment other than chlorine, the possibility of secondary harmful substances and carcinogenic substances are raised. In addition, the volume of emissions is a major concern for international shipping of vessels. 2009 McCollim According to the study, the emission of greenhouse gas from the world is about 3% and 43% of it is international shipping. In the case of data released by IMO in 2005, CO2 emissions from international maritime transport and coastal transportation Respectively, of 770 million tons and 175 million tons, respectively, and it is expected that it will increase by more than 30% by 2020 by more than 1.0 billion tons in 2007, Eyring and others will increase to 120% by 2050.

Currently, there are Tekros, NK, Panashia and Hyundai Heavy Industries in Korea, and Alfa Laval in Norway and Hamamm in Germany. The two technologies are electrolysis, enkei ozone treatment, Panacea ultraviolet disinfection, and Hyundai Heavy Industries are handling ship ballast water by ultraviolet and electrolysis.

As a prior art for ballast water treatment using ship exhaust gas, there is a ballast water treatment method and treatment apparatus (application number: 10-2009-0111725) using exhaust gas of ship engine of Xinjiang HiTech, Tank and method of treating greenhouse gas of ship using it (Application No: 10-2011-0034248), and a similar method to this technology is used, but Application No. 10-2009-0111725 is applied to treatment of ship using ballast water treatment tank It is a completely different ballast water treatment method structurally separated from the ship ballast water tank and the ballast water tank by the method of mixing the heat exchange type and it costs considerably to install the structure as shown in the drawing, , The contact time is too short, which is a very disadvantageous method in terms of effective biological killing.

Carbon dioxide is a typical gas that causes climate warming. Carbon dioxide is an acidic gas when it is dissolved in water, and the pH is rapidly decreased depending on the dissolution state and concentration. Particularly, when dissolved in water, such as SOx and NOx, the pH decrease rate appears more rapidly, and there are typically acid rain and acid snow. Especially in snow, due to the temperature and structural problems, the carbon dioxide dissolution rate is high and the pH is lower than the acid rain rate. Studies have shown that using these dissolution characteristics of carbon dioxide can kill plankton, larvae, spores, protozoa, bacteria, and bacteria present in seawater.

 Conventional ship equilibrium water management methods recommend replacing ballast water more than 200 nautical miles from the land and 200 meters or more in depth.

There are various techniques for ship ballast water treatment. However, considering the shipowner 's viewpoint, the unit cost and treatment efficiency of the treatment facilities are a big problem. Furthermore, in the case of existing vessels, the installation of the ballast water treatment system is costly to a large extent without leaving the ship's ordinance.

In the present invention, the combustion gas discharged during the operation of a ship is captured and cooled, and then the combustion gas is introduced into the absorption tower. Then, the particulate matter, the black dust and the oil are removed using sedimentation and floating, The combustion gas is sprayed using the injection nozzle to dissolve in the seawater particles to dissolve the maximum amount of SOx and NOx besides carbon dioxide and send it to the ballast water tank to reduce the pH of the ballast water, And to provide a ship equilibrium biological killing apparatus.

The problem to be solved here is the cooling of the combustion gas first. If the combustion gas is not cooled, it is not easy to separate soot, particulate matter, and oil in the combustion gas primarily, and the ultrafine nozzles in the absorption tower are clogged to make it impossible to collect the gas and degrade the solubility of the gaseous material The pH is not reduced and the biological killing effect is substantially lost. Therefore, the combustion gas is preferably firstly reduced in temperature, and secondarily, a method of increasing the solubility so as to dissolve the cooled combustion gas to the maximum is provided.

When the solubility is lowered, the effect of reducing the pH due to carbon dioxide is reduced. Therefore, it is difficult to expect a desired biological killing effect. Next, the contact time between the pH-reduced ballast water and the organism should be maximized. Experimental results showed that 95% of the native organisms and phytoplankton were killed during 3 minutes of contact time and 95% of the larvae were contacted for 9 minutes. Therefore, the method that can control the contact time between the ballast water and the organism is the biggest obstacle to the effect of the ballast water treatment.

Therefore, if the problem to be solved is solved, the ship ballast water treatment apparatus can exhibit its efficiency very efficiently, and it is possible to perform the treatment in a simple and convenient manner, which is advantageous in that ballast water production and installation costs are reduced.

The technical problems to be solved by the present invention are not limited to the technical problems mentioned above, but it is also possible to provide a real-time measurement system for the ballast water management during the operation of the ship and prevent marine pollution and air pollution combined with the present ballast water management system Several workarounds for this need to be addressed.

The technical objects to be achieved by the present invention are not limited to the above-mentioned technical problems.

In order to accomplish the above object, a ship equilibrium biological killing apparatus using combustion gas according to the present invention comprises a collecting section for collecting combustion gas, the collecting section being disposed at a discharge port through which fuel is burnt through an engine of a ship and an exhaust gas is discharged, A cooling unit installed outside the pipe for transferring the combustion gas collected in the pipe to cool the pipe to cool the combustion gas passing through the pipe; and a reaction for dissolving the foreign substance of the combustion gas introduced through the pipe into the ballast water A ballast water storage unit connected to the reaction unit to store the ballast water flowing from the outside and inject the ballast water into the reaction unit and to receive and store the dissolved water in which the foreign substances of the combustion gas are dissolved, And a crusher connected to the ballast water storage part to crush foreign substances contained in the ballast water flowing from the outside.

Specifically, the collecting part may be provided in the form of a hood at an uppermost position of a discharge port through which the combustion gas is discharged, and a suction fan for sucking the combustion gas may be installed.

As described above, according to the present invention, the combustion gas discharged during the operation of a ship is collected, and the gas is cooled. Then, the combustion gas enters the absorption tower, and then the sedimentation and flooding are used to remove particulate matter, It dissolves in the seawater particles by using the super-fine injection nozzle to dissolve the combustion gas, dissolving the maximum amount of SOx and NOx besides carbon dioxide and sending it to the ballast water tank to decrease the pH of the ballast water, So that the ballast water treatment apparatus can exhibit its performance very efficiently and can be processed by a simple and convenient method, resulting in an advantage that the manufacturing cost of the ballast water is reduced.
