Description

와류식 배출 후드Vortex Discharge Hood
본 발명은 대형 산업 현장에서 발생되는 분진이나 흄 등의 오염 물질이 함유된 공기를 흡입하여 작업장 외부로 배출하는 와류식 배출 후드에 관한 것으로, 보다 상세하게는 기계적인 작동 부위가 없고, 후드 내부로 분사되는 공기에 의한 와류가 후드 내부에 발생되어 후드 내부 및 주변의 오염된 공기를 강한 흡입력으로 흡입하여 배출시킬 수 있으며, 후드 내부로 공기를 분사하기 위한 구조를 유닛화하여 후드의 제조 및 유지보수가 용이한 와류식 배출 후드에 관한 것이다.The present invention relates to a vortex type discharge hood that sucks air containing contaminants such as dust or fumes generated in a large industrial site and discharges it to the outside of the workplace. More specifically, there is no mechanical operating part. Vortex caused by the injected air is generated inside the hood, so that contaminated air in and around the hood can be sucked out with a strong suction force, and the hood is manufactured by unitizing a structure for injecting air into the hood. And a vortex discharge hood which is easy to operate.
일반적으로, 제철소, 주물공장, 석탄 화력발전소, 미곡 종합처리장, 시멘트 공장 등의 대형 산업 현장에서는 분진이나 흄 등의 물질이 함유된 오염된 공기가 대량 발생되며, 이러한 오염된 공기는 작업자의 건강에 직접적으로 영향을 미치는 것을 물론이고, 작업장 및 그 주변의 환경을 오염시키는 원인이 되고 있다.In general, large industrial sites such as steel mills, foundries, coal-fired power plants, rice flour treatment plants, and cement plants generate large amounts of polluted air containing substances such as dust and fumes. Not only directly affecting, but also causing the pollution of the workplace and the surrounding environment.
따라서, 오염물질이 발생되는 구역에 후드를 설치하여 오염된 공기를 강제로 흡입하여 배출하도록 하고 있다. 참고로 후드로 흡입되는 오염된 공기는 배출덕트를 통하여 작업장의 외부에 설치된 집진기로 보내지며, 집진기는 오염된 공기 중의 오염물질을 여과한 후, 여과된 공기를 대기로 방출하게 된다.Therefore, the hood is installed in the area where the pollutant is generated to force the polluted air to be sucked out. For reference, the contaminated air sucked into the hood is sent to the dust collector installed outside the workplace through the exhaust duct, and the dust collector filters the contaminants in the contaminated air and then discharges the filtered air to the atmosphere.
한편, 종래의 후드는 공기 흡입구의 단면 형상이 원형 또는 사각형으로 되어 있으며 위로 갈수록 면적이 좁아지는 형상으로 되어 있다. 또한 후드의 상단부에는 공기를 배출하는 배출덕트의 한 단이 연결되고, 상기 배출덕트의 다른 단에는 블로워와 같은 공기배출장치가 설치된다.On the other hand, the conventional hood has a circular or rectangular cross-sectional shape of the air intake port, and has a shape in which the area is narrowed upward. In addition, one end of the discharge duct for discharging air is connected to the upper end of the hood, and an air discharge device such as a blower is installed at the other end of the discharge duct.
이러한 종래의 후드는 공기배출장치의 가동으로 인해 발생되는 흡입력을 이용하여 오염 공기를 후드의 내부로 흡입하여 배출하는 방식으로, 후드로 유입되는 공기 흐름의 유선 분포가 후드 내부와 하방 공간에 한정되어 분포하는 관계로 국소 구역 공간의 공기만 배출되고, 후드 외부 주변의 공간에 있는 오염공기는 배출하지 못함에 따라 오염공기 배출 효율이 낮은 문제점이 있다.The conventional hood is a method of inhaling and discharging contaminated air into the hood by using the suction force generated by the operation of the air discharge device, and the streamline distribution of the air flow flowing into the hood is limited to the inside and the lower space of the hood. Due to the distribution, only the air in the local area space is discharged, and the polluted air in the space around the outside of the hood is not discharged, there is a problem of low polluted air discharge efficiency.
상기와 같은 문제점을 해결하려는 여러 방안들이 제안되고 있다.Various solutions have been proposed to solve the above problems.
일본 공개특허공보 제1989-38540호에는 4개의 지주로부터 공기류를 토출하여 나선상의 상승 와류를 발생시키며 해당 공간의 중심부에서 상승 와류에 직교하는 방향으로 흡기작용을 생성하도록 한 것이 제안된 바 있다.Japanese Laid-Open Patent Publication No. 1989-38540 proposes to discharge air flows from four struts to generate spiral rising vortices and to generate intake in a direction orthogonal to the rising vortices at the center of the space.
그러나, 상기 특허문헌에 개시된 기술은 배기 덕트에 연속하는 흡입구의 단면 형상이 원형으로 된 배기 후드의 배기구 중심에 대해 접선방향으로 공기를 토출하는 구조로, 공기분출구와 하방측 바닥 방향으로 공기를 분출하는 공기분출구 또는 공기 유입을 위한 블레이드를 다수 설치할 필요가 있는 발명으로 구조가 복잡하며, 작동하는 부품을 구동하는 동력의 공급이 요구되며, 구동 동력의 가동에 따른 소음이 발생하는 단점이 있다.However, the technique disclosed in the above patent document is a structure in which air is discharged in a tangential direction with respect to the center of the exhaust port of the exhaust hood having a circular cross-sectional shape of the inlet port continuous to the exhaust duct, and the air is ejected in the air outlet port and the bottom bottom direction. It is an invention that needs to install a plurality of blades for the air outlet or air inlet to the complicated structure, it is required to supply the power to drive the operating parts, there is a disadvantage that the noise generated by the operation of the drive power.
한편, 미국등록특허 US 6,851,421 B2와 미국특허공개 US 2007/0015449 A1에는 레인지 하부에서 수직 상방으로 저속 분출되는 에어 제트에 의하여 발생되는 와류의 영향으로 레인지에서 발생되는 흄이 레인지를 벗어나지 않고 후드로 흡입되어 배출되는 구조가 개시되어 있으나, 배출 공기가 후드 하방 공간으로 제한되는 단점이 있다.On the other hand, US Patent No. 6,851,421 B2 and US Patent Publication No. US 2007/0015449 A1 show that the fumes generated in the range are sucked into the hood without leaving the range due to the vortices generated by the air jet that is ejected at a low speed vertically upward from the bottom of the range. Disclosed is a structure that is discharged, but there is a disadvantage that the exhaust air is limited to the space under the hood.
이처럼 종래의 여러 방안들은 레인지 후드의 밑단에 원심 팬을 설치하거나, 가이드 베인을 설치하거나, 레인지 앞면에 에어 커튼 방식의 공기 흐름으로 스월링(Swirling)을 유발하거나, 원추형 후드 측면의 원형관으로 공급되는 공기에 의한 스월 발생 및 후드 상부에 설치된 하나의 관으로 공기가 배출되는 구조와 방식으로 되어 있으며, 배출되는 공기가 후드 하방의 공간으로 한정되어 후드 주위 공간의 오염 공기를 배출하지 못하는 문제점이 있다.Many conventional methods like this include installing a centrifugal fan at the bottom of the range hood, installing a guide vane, causing swirling with an air curtain type air flow at the front of the range, or supplying a circular tube on the side of the conical hood. Swirl generated by the air and the air is discharged to a single tube installed in the upper hood, and the discharged air is limited to the space below the hood there is a problem that can not discharge the polluted air in the space around the hood .
