Abstract

The present invention relates to a heat exchange system for a vessel engine. According to the present invention, the heat exchange system for a vessel engine reuses sucked air of a high temperature/a high pressure, discharged into the air when a combustion pressure of a combustion chamber becomes abnormally high as air density sucked to an engine becomes high due to a low atmosphere temperature when a vessel sails in polar regions. The heat exchange system for a vessel engine includes: a blow-off valve installed in an outlet of a compressor of a turbocharger and opened when the pressure of the sucked air to the engine is equal to or higher than a predetermined value; a vortex tube dividing the sucked air passing through the blow-off valve into low-temperature air in which the temperature is relatively lower than that of the sucked air and high-temperature air in which the temperature is relatively higher than that of the low-temperature air, by vortex (spiral rotation); an intake chamber storing the low-temperature air separated from the vortex tube; and a discharge chamber storing the high-temperature air separated from the vortex tube. Therefore, the heat exchange system for a vessel engine can improve energy reducing efficiency of the vessel by transferring the sucked air of the high temperature and the high pressure, discharged into the air by the blow-off valve, to the inlet of the turbocharger, a front end of an SCR catalyst, and heating of the vessel.

Description

선박 엔진용 열교환 시스템{Heat Exchange System for Marine Engines}[0001] Heat Exchange System for Marine Engines [

본 발명은 선박 엔진용 열교환 시스템에 관한 것으로, 더욱 상세하게는 엔진 보호를 위해 블로우 오프 밸브에 의해 대기중으로 배출되는 고온 고압의 흡입공기를 열교환에 의해 선박에 재사용하는 선박 엔진용 열교환 시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a heat exchange system for a marine engine, and more particularly, to a heat exchange system for a marine engine in which hot air of high temperature and high pressure discharged into the atmosphere by a blow- .

선박의 추진용 엔진이나 발전용 엔진 등에서는 연료의 연소에 따른 배기가스가 발생한다. 이러한 배기가스는 엔진의 출력 등에 따른 차이는 있으나 상당한 고온으로 배출된다.In a propulsion engine or a power generation engine of a ship, exhaust gas is generated due to combustion of fuel. Such exhaust gas is discharged at a considerably high temperature although there is a difference depending on the output of the engine and the like.

일반적으로 선박의 추진용 또는 발전용 엔진에서 연료를 연소하여 발생하는 열 에너지 중 대략 50% 정도는 각각 추진이나 발전에 사용되지만, 나머지는 대부분 배기가스의 형태 또는 엔진 냉각수에 대한 열교환을 통한 냉각 등을 통해 외부로 배출되는 형태의 폐열로 버려진다.Generally, about 50% of the thermal energy generated by combustion of fuel in a propulsion or power generation engine of a ship is used for propulsion or power generation respectively, but the remainder is mostly used for cooling of the exhaust gas or heat exchange for engine cooling water And is discharged to the outside through the waste heat.

이와 같은 폐열 중 일부라도 회수하여 활용하게 되면 선박에서 소비되는 연료를 절감할 수 있고, 에너지 효율을 높일 수 있다.If some of such waste heat is recovered and utilized, the fuel consumed by the ship can be saved and energy efficiency can be increased.

또한 최근에는 외부로 배출되는 폐열 중 일부를 회수함으로써 에너지를 절감할 수 있는 고효율의 선박 또는 친환경 선박에 대한 필요성이 제기됨에 따라, 이미 선박 분야에서는 수년 전부터 엔진으로부터 배출되는 고온의 배기가스를 직접 작동 유체로 사용하는 가스터빈(또는 파워 터빈이라고 함)과 고온의 배기가스의 열을 이용하여 생성된 증기의 일부를 작동 유체로 사용하는 증기터빈 등을 추가로 설치하여 전력을 생산할 수 있도록 한 이른바 폐열회수장치(WHRS: Waste Heat Recovery System)를 적용하고 있다.In recent years, there has been a need for a highly efficient ship or an eco-friendly ship capable of saving energy by recovering a part of the waste heat discharged to the outside. Thus, in the ship sector, the high temperature exhaust gas discharged from the engine has been directly operated (Or power turbine) used as a fluid, and a steam turbine using a part of the steam generated by using heat of a high-temperature exhaust gas as a working fluid to generate electric power, so-called waste heat (WHRS: Waste Heat Recovery System).

이외에도, 배기가스는 엔진과 연결되어 있는 터보차저(turbo charger)로 공급되어 터보차저의 동력원으로 사용된다.In addition, the exhaust gas is supplied to a turbo charger connected to the engine and used as a power source for the turbocharger.

그러나, 종래의 선박 엔진은 선박이 극지방 운항시에 낮은 대기온도로 인하여 엔진으로 흡입되는 공기 밀도가 높아져 연소실의 연소압력이 비정상적으로 높아지며 엔진 노킹(knocking)이 발생하는 문제점이 있다.However, in the conventional marine engine, the air density to be sucked into the engine is increased due to the low atmospheric temperature when the ship is operating in the polar region, so that the combustion pressure in the combustion chamber becomes abnormally high and engine knocking occurs.

이러한 노킹존(knocking zone)에 근접한 급격연소를 방지하고 엔진을 보호하기 위하여 종래에는 터보차저의 압축기 출구에 블로우 오프 밸브(blow-off valve)를 설치하여 인위적으로 공기를 대기중에 방출시키게 된다.In order to prevent sudden combustion near the knocking zone and to protect the engine, a blow-off valve is conventionally installed at the compressor outlet of the turbo charger to artificially discharge air into the atmosphere.

이때, 블로우 오프 밸브를 통해 배출되는 고온의 압축공기는 대기중에 방출되면서 엄청난 소음이 동반되며, 고온/고압의 유효한 에너지원이 쓸모없는 폐자원으로 버려지게 된다.At this time, the high-temperature compressed air discharged through the blow-off valve is discharged into the atmosphere and is accompanied by a great noise, and a high-temperature / high-pressure effective energy source is discarded as useless waste resources.

따라서, 블로우 오프 밸브에 의해 대기중으로 배출되는 고온 고압의 흡입공기를 선박에 재사용하는 선박 엔진용 열교환 시스템의 개발이 요구되고 있는 실정이다.Therefore, there is a need to develop a heat exchange system for a ship engine that reuses the high-temperature, high-pressure intake air discharged into the atmosphere by the blow-off valve to the ship.
