Description

흡수식 미세조류 탈수장치Absorption Microalgae Dehydration System
본 발명은 흡수식 미세조류 탈수장치에 관한 것으로, 보다 상세하게는 다수의 통공이 형성된 회전드럼의 내부로 미세조류입자가 포함된 현탁액이 공급되면, 회전드럼의 외주면에 외장된 흡수부재가 통공을 거쳐 현탁액의 수분을 흡수하고, 흡수된 수분은 압착롤의 가압에 의해 탈수시켜 분리 배출시키며, 수분이 제거된 현탁액은 하향 경사지게 설치되는 회전드럼의 경사도에 의해 회전드럼의 타측으로 자동 배출될 수 있도록 구성된 흡수식 미세조류 탈수장치에 관한 것이다.The present invention relates to an absorption type microalgae dehydration device, and more particularly, when a suspension containing microalgae particles is supplied into a rotating drum in which a plurality of through holes are formed, an absorbing member external to the outer circumferential surface of the rotating drum passes through the through hole. It absorbs the water in the suspension, and the absorbed water is dehydrated by pressing the pressing roll to separate and discharged, and the suspended water is automatically discharged to the other side of the rotating drum by the inclination of the rotating drum installed downwardly. It relates to an absorption microalgae dehydration device.
일반적으로 탈수는 피탈수물에서 수분을 제거하는 것을 주목적으로 하는 과정을 의미하며 탈수의 대상은 채취된 광물에서부터 하수슬러지, 미세조류, 목재펄프 등 다양하게 존재한다. 특히, 미세조류의 탈수는 최근 바이오에너지에 대한 관심이 커짐에 따라 중요해지고 있다.In general, dehydration means a process that is mainly to remove the water from the dehydrated water, and the object of dehydration exists from the collected minerals, sewage sludge, microalgae, wood pulp. In particular, dehydration of microalgae has become important as interest in bioenergy has increased recently.
미세조류입자는 해양이나 민물에서 광합성을 통해 성장하는 조류의 일종으로 크기는 대략 수 마이크로미터에서 수백 마이크로미터에 이른다.Microalgae particles are a type of algae that grow through photosynthesis in the ocean or in fresh water and range in size from a few micrometers to hundreds of micrometers.
마이크로 단위의 미세조류입자가 포함된 해수나 민물은 희박한 현탁액과 같고 초기 함수율은 약 99.99 wt%이다. 그러므로 기존 탈수장치를 이용할 경우 탈수를 위한 막대한 에너지비용을 지불해야 한다. Seawater or freshwater containing microalgal particles in microunits is like a lean suspension with an initial moisture content of about 99.99 wt%. Therefore, when using the existing dehydration device, a huge energy cost for dehydration must be paid.
따라서 함수율이 높은 미세조류입자가 포함된 현탁액을 일정한 함수율로 낮출 경우 본 탈수과정에서 보다 적은 에너지와 저렴한 에너지비용이 소요되는 것이 선행되어야 한다.Therefore, when the suspension containing the microalgal flow particles having a high moisture content is lowered to a constant moisture content, it should be preceded that less energy and lower energy cost are required in this dehydration process.
통상 탈수에 쓰이는 장치는 원심식, 벨트프레스식, 진공여과식, 가압여과식 등이 있으며 이들 탈수장치는 대부분 하수슬러지나 광물의 탈수에 사용되고 있다. 하수슬러지나 광물의 탈수에 쓰이는 장치는 주로 물과 비교하여 비중이 크거나 입자의 크기가 큰 고체입자의 여과 및 탈수에 적합하다.Conventional dehydration devices are centrifugal, belt press, vacuum filtration, pressure filtration, etc. These dehydration devices are mostly used for sewage sludge or mineral dehydration. The equipment used for sewage sludge or mineral dewatering is mainly suitable for the filtration and dewatering of solid particles with a specific gravity or a large particle size compared to water.
특히 비중이 큰 고체입자의 여과장치로는 "슬러리 및 자원 재활용 여과장치(등록번호: 제10-1181893호)"가 있다.Particularly, a filtration device for solid particles having a high specific gravity is "slurry and resource recycling filtration device (Registration No .: 10-1181893)".
이러한 종래의 장치는 오폐수의 입자상 물질을 제거하기 위한 장치로써, 드럼필터를 여과수에 수장시켜 내부로 여과처리된 처리수가 유입되도록 하고, 드럼필터의 표면에 붙은 이물질은 압착롤러를 통해 물기를 제거한 후, 스크레이퍼로 물기가 제거된 이물질을 분리하도록 구성된다.Such a conventional apparatus is a device for removing particulate matter of waste water, and the drum filter is enclosed in the filtered water to allow the filtered water to flow therein, and the foreign matter adhering to the surface of the drum filter is removed through a pressing roller. It is configured to separate the dehydrated foreign matter with a scraper.
하지만 이러한 종래의 장치는 하기와 같은 문제점이 있다.However, these conventional devices have the following problems.
첫째: 입자가 큰 슬러리의 고액을 분리할 때는 적합하지만 마이크로 단위의 미세조류입자를 획득하기 위한 장치로 사용할 경우에는 일반적인 필터로 필터링하기 어렵다.Firstly, it is suitable for separating solid solution of large particle slurry, but it is difficult to filter by general filter when used as a device for obtaining microalgal particles of micro unit.
둘째: 드럼필터의 공극이 매우 커 수분과 함께 마이크로입자상의 이물질도 드럼필터의 내부로 유입되는 문제점이 발생된다.Secondly, the air gap of the drum filter is very large, and foreign matters on the microparticles along with the moisture are also introduced into the drum filter.
셋째: 장치가 복잡하여 시설비 및 운용비가 많이 드는 문제점이 발생된다.Third, the device is complicated, which causes a lot of facilities and operating costs.
본 발명은 상기와 같은 문제점을 감안하여 안출된 것으로, 본 발명의 제 1목적은, 수분을 흡수하는 흡수부재의 처짐과 형상변형을 방지하고, 또한 단일 회전드럼으로 수분과 수분이 제거된 미세조류현탁액을 분리배출 할 수 있도록 구성된 흡수식 미세조류 탈수장치를 제공하는데 있다.The present invention has been made in view of the above problems, and the first object of the present invention is to prevent sagging and shape deformation of an absorbing member that absorbs moisture, and also removes water and moisture in a single rotating drum. The present invention provides an absorbent microalgae dehydration apparatus configured to separate and discharge a suspension.
본 발명의 제 2목적은, 미세조류입자의 현탁액을 탈수시키고, 자중에 의해 탈수된 미세조류입자를 이송시킬 수 있게 하여 운용비를 절감할 수 있도록 구성된흡수식 미세조류 탈수장치를 제공하는데 있다.It is a second object of the present invention to provide a water-absorbing microalgae dehydration apparatus configured to dehydrate the suspension of microalgae particles and to transport the microalgae particles dehydrated by their own weight to reduce operating costs.
