Description

일체형 공기압축기 폐열회수장치{Waste heat recovery apparatus of air compressor}Waste heat recovery apparatus of air compressor

본 발명은 공기압축기 폐열회수장치에 관한 것으로서, 더욱 상세하게는 선박에 설치가 용이하도록 공기압축수단과 공기압축수단의 폐열을 회수하는 폐열회수수단이 일체형으로 이루어지는 일체형 공기압축기 폐열회수장치에 관한 것이다.The present invention relates to an air compressor waste heat recovery device, and more particularly, to an integrated air compressor waste heat recovery device in which an air compression means and a waste heat recovery means for recovering waste heat from the air compression means are integrated to facilitate installation on a ship. .

최근 국제해사기구(IMO, International Maritime Organization)는 선박배출가스에 대한 기준 강화 및 세계 주요 국가의 배출규제해역(ECA, Emission Control Area)을 확대하는 등 전 세계 해역을 항행하는 선박들의 황산화물 배출량을 저감시키기 위한 환경적 규제가 강화되고 있다.Recently, the International Maritime Organization (IMO) has strengthened standards for ship emissions and expanded the emission control area (ECA) of major countries in the world to reduce sulfur oxide emissions from ships navigating around the world. Environmental regulations for reduction are being strengthened.

그에 따라 환경규제에 대비하기 위한 친환경 고효율·고연비 선박에 대한 수요가 점차 증가되고 있으며, 이에 대한 대응책으로 에너지 효율을 향상시킬 수 있도록 선박에서 발생되는 폐열을 회수하여 다양한 에너지원으로 활용할 수 있도록 하는 폐열회수 기술이 적용되고 있다.Accordingly, the demand for eco-friendly, high-efficiency, high-fuel-efficient ships to prepare for environmental regulations is gradually increasing, and as a countermeasure to this, waste heat generated from ships is recovered and used as various energy sources to improve energy efficiency. Recovery technology is being applied.

한편, 한국공개특허 제10-2014-0147506호와 같이, 선박에서 사용되는 공기압축기에서, 공기를 압축하는 과정에서 발생되는 폐열을 회수하여 에너지원으로 활용하도록 함으로써 에너지 효율을 증대시킬 수 있는 기술들이 개발되고 있다.Meanwhile, technologies that can increase energy efficiency by recovering waste heat generated in the process of compressing air in an air compressor used in ships and utilizing it as an energy source, such as Korean Patent Laid-Open Patent No. 10-2014-0147506, are available.

By adding a waste heat recovery device, it is intended to increase energy efficiency in the ship.
