Abstract

A chimney structure of vessel is provided to reduce installing and maintaining costs by installing an air injection unit in an exhaust pipe for improving exhaust efficiency. A chimney structure of vessel includes an exhaust pipe(10) and an air injection unit. The exhaust pipe is installed on the vessel for exhausting exhaust gas generated while driving an engine. The air injection unit includes a pump(20), an air passage(30), and a nozzle(40). The pump generates air pressure to pass through the air passage to the nozzle. The air passage connects the pump and the nozzle for transferring the air pressure up to the nozzle. The nozzle injects air pressure into the exhaust pipe to increase in an exhaust speed of the exhaust gas for reducing contamination of the vessel.

본 발명은 선박의 배기가스 배출성능 향상를 위한 연돌구조에 관한 것이다.The present invention relates to a stack structure for improving the exhaust gas emission performance of the ship.

본 발명은 선박에 연돌에 설치되는 배기관에 상기 배기관으로부터 배출되는 배기가스의 배출성능 향상을 위한 공기분사장치를 간단히 설치하여 상기 배기가스로 인한 선박의 오염을 효과적으로 줄일 수 있도록 한 것이다.The present invention is to simply reduce the pollution of the vessel due to the exhaust gas by simply installing an air injector for improving the exhaust performance of the exhaust gas discharged from the exhaust pipe in the exhaust pipe installed in the stack on the vessel.

일반적으로 선박에는 도 2에서와 같이 거주구의 일측에 배기관이 입설된 연돌이 설치되어 운항중 발생되는 배기가스를 상기 연돌의 배기관을 통해 선박의 외 부로 배출시켜 주게 된다.In general, a ship is provided with a stack of exhaust pipes installed on one side of the inlet as shown in Figure 2 to discharge the exhaust gas generated during operation to the outside of the ship through the exhaust pipe of the stack.

그러나 상기 배기가스가 풍향/풍속에 의해 영향을 받게 되는 경우 선미부쪽으로 정상적으로 배출되지 아니하고 선미쪽으로 흘러 선박을 오염시키거나 선원에게 좋지 못한 영향을 주게 된다.However, when the exhaust gas is affected by the wind direction / wind speed, the exhaust gas is not normally discharged to the stern portion, but flows to the stern, contaminating the vessel or adversely affecting the crew.

이를 위해 종래에는 상기 배가가스로 인한 선박의 오염과 선원의 건강을 고려하여 연돌의 높이와 배기관의 높이를 가급적 높이는 정도로 설계하고 있으나 이역시 극히 수동적인 탈피수단에 불과하여 일부 선박에 집진 장치, SO2, NO2 저감장치 등을 설치하고 있으나 선박의 공간을 많이 차지 할 뿐만 아니라 비용이 고가이기 때문에 적용에 부담을 초래하고 있는 실정이어서 선박의 오염방지 및 선원의 건강유지를 위해 배기가스로 인한 문제들을 근본적으로 해결하는 구조적인 보완이 시급히 마련되어야 할 것이다.To this end, conventionally designed to increase the height of the stack and the height of the exhaust pipe as much as possible in consideration of the pollution of the vessel and the health of the source due to the doubling gas, but in this case, it is an extremely passive stripping means, so that some ship dust collector, SO2 And NO2 abatement system are installed, but they are not only occupying a lot of space of the ship but also costly, which is causing burden on the application. In order to solve this problem, structural complements need to be prepared.

본 발명은 선박에 연돌에 설치되는 배기관에 상기 배기관으로부터 배출되는 배기가스의 배출성능 향상을 위한 공기분사장치를 간단히 설치하여 상기 배기가스로 인한 선박의 오염을 효과적으로 줄일 수 있도록 함을 목적으로 한다.The present invention aims to effectively reduce the pollution of the vessel due to the exhaust gas by simply installing an air injection unit for improving the exhaust performance of the exhaust gas discharged from the exhaust pipe in the exhaust pipe installed in the stack in the ship.

이를 위해 본 발명은 선박의 연돌에 배기가스의 배출을 위해 설치되는 배기관에 상기 배기관으로부터 배출되는 배기가스의 배출 성능향상을 위한 공기분사장치를 설치하여 상기 배기가스로 인한 선박의 오염을 효과적으로 줄일 수 있도록 한 선박의 배기가스 배출성능 향상를 위한 연돌구조를 제공함으로써 상기 목적을 달성하고자 한다.To this end, the present invention can effectively reduce the pollution of the vessel due to the exhaust gas by installing an air injection device for improving the emission performance of the exhaust gas discharged from the exhaust pipe in the exhaust pipe installed for the exhaust gas in the stack of the ship In order to achieve the above object by providing a stack structure for improving the exhaust gas emission performance of a ship.

이하, 본 발명 선박의 배기가스 배출성능 향상를 위한 연돌구조에 대한 바람직한 일실시예를 첨부도면을 참조로 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the stack structure for improving exhaust gas emission performance of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 선박의 연돌에 배기가스의 배출을 위해 설치되는 배기관(20)에 상기 배기관(20)으로부터 배출되는 배기가스의 배출 성능향상을 위한 공기분사장치를 설치하여 상기 배기가스로 인한 선박의 오염을 줄일 수 있도록 하는 것을 특징으로 한다.The present invention is installed in the exhaust pipe 20 for the discharge of the exhaust gas in the stack of the ship by installing an air jet for improving the exhaust performance of the exhaust gas discharged from the exhaust pipe 20 to contaminate the ship due to the exhaust gas It is characterized in that to reduce the.

상기 공기분사장치는 배기관(20)의 내측에 공기를 공급하기 위해 설치되는 펌프(30)를 설치하되, 상기 배기관(20)의 출구측 안쪽에 설치되는 노즐(50)을 설치하는 한편, 상기 펌프(30)와 노즐(50)을 공급관(40)으로 상호 연결하여 된 구조로 제공된다. The air spraying device is provided with a pump 30 which is installed to supply air to the inside of the exhaust pipe 20, while installing a nozzle 50 installed inside the outlet side of the exhaust pipe 20, the pump 30 and the nozzle 50 are provided in a structure by interconnecting the supply pipe 40.

본 발명은 배기관(20)의 내측에 별도로 펌프(30)를 설치하고 있으나 경우에 따라서 상기 별도의 펌프(30)를 배기관(20)에 설치하지 아니하고 선박에 이미 설치되어 있는 펌프(30)를 사용할 수도 있다.According to the present invention, the pump 30 is separately installed inside the exhaust pipe 20, but in some cases, the pump 30 that is already installed in the ship may be used without installing the separate pump 30 in the exhaust pipe 20. It may be.

본 발명은 선박에 연돌에 설치되는 배기관(20)에 상기 배기관(20)으로부터 배출되는 배기가스의 배출성능 향상을 위한 공기분사장치를 간단히 설치하여 상기 배기가스로 인한 선박의 오염을 효과적으로 줄일 수 있도록 하고 있는 것이다.The present invention is to simply install an air injector for improving the exhaust performance of the exhaust gas discharged from the exhaust pipe 20 in the exhaust pipe 20 installed in the stack to the ship to effectively reduce the pollution of the vessel due to the exhaust gas I'm doing it.

본 발명에서와 같이 공기분사장치를 배기관(20)의 내측에 구성한 상태에서 선박 운항중 배기관(20)으로 배기가스를 배출시킴과 동시에 펌프(30)를 작동시켜 노즐(50)을 통해 상기 배기가스의 배출속도보다 빠르게 공기를 분사하게 되면 상기 배기가스가 배출되는 공기와 함께 배기관(20)을 신속하게 빠져나와 선미부로부터 멀어지게 되어 결국 유해한 배기가스로부터 선원의 건강을 유지할 수 있게 됨은 물론 선박의 오염을 효과적으로 줄일 수 있게 되며 이와 같이 공기분사장치로 배기가스의 배출 속도를 높여주게 되면 선박에 별도의 집진 장치나 부가 장치가 필요하지 않으므로 경제적인 이득을 취할 수 있고 또한 설치 및 유지 보수 또한 간단하게 이루어질 수 있을 것이다.In the state in which the air injection unit is configured inside the exhaust pipe 20 as in the present invention, the exhaust gas is discharged to the exhaust pipe 20 while the ship is operating, and the pump 30 is operated to operate the exhaust gas through the nozzle 50. When the air is injected faster than the discharge speed of the exhaust gas is discharged quickly with the air discharged from the exhaust pipe 20 is far away from the stern, which can maintain the health of the source from harmful exhaust gas as well as of the vessel It is possible to effectively reduce pollution and to increase the discharge rate of the exhaust gas through the air injector, so that the ship does not need a separate dust collector or an additional device, and thus can obtain economic benefits and simplify installation and maintenance. Could be done.
