여과집진장치{Dust collecting apparatus using filter bags}Dust collecting apparatus using filter bags

본 발명은 여과집진장치에 관한 것으로서, 보다 상세하게는 본체 내부의 자유단인 필터백의 하단부를 고정시킬 수 있도록 함으로써, 서로간의 마찰이나 부딪힘 등에 의해 필터백의 터지는 것을 방지함은 물론 필터백이 정지된 상태에서 안정적으로 분진을 필터링 할 수 있게 되어 결과적으로 필터링 효율을 향상시킬 수 있도록 하는 여과집진장치에 관한 것이다.The present invention relates to a bag filter, and more particularly, by allowing the lower end of the filter bag, which is a free end inside the main body, to be fixed, thereby preventing the filter bags from bursting due to friction or collision with each other, as well as the filter bag being stopped. The present invention relates to a filter dust collector that can stably filter dusts and thereby improve filtering efficiency.

일반적으로 여과집진장치는 대기오염 방지시설 중 하나로서, 외부의 함진가스를 본체 내부로 유입하여 필터백을 거치는 동안 분진이 여과되도록 하는 것을 말한다.In general, the bag filter is one of the air pollution prevention facilities, and means that the dust is filtered while the outside of the dust-containing gas flows into the body through the filter bag.

일례로 종래 기술의 여과집진장치에 대해 첨부된 도면을 참고하여 살펴보면 다음과 같다.As an example, referring to the accompanying drawings for a conventional bag filter as follows.

도 1에서 나타내듯이, 종래 기술의 여과집진장치는 상부 원통형 구조의 본체(10)와 하부 원추형 구조의 호퍼(20)로 이루어지되, 상기 호퍼(20)의 일측에 함진가스가 유입되는 인입구(21)가 마련되고, 이 인입구(21)의 상방인 본체(10) 내부에 복수의 필터백(30)이 설치되며, 이 필터백(30)을 거친 여과가스가 외부로 배출 되도록 본체(20)의 상단부에 배기구(12)가 형성되는 구성으로 되어 있다.As shown in Figure 1, the prior art filter dust collecting device is composed of themain body 10 of the upper cylindrical structure and thehopper 20 of the lower conical structure, theinlet port 21 is the inlet gas is introduced into one side of the hopper 20 ) Is provided, a plurality offilter bags 30 are installed inside themain body 10 that is above theinlet 21, and the filtration gas passing through thefilter bag 30 is discharged to the outside. Theexhaust port 12 is formed in the upper end portion.

그리고, 상기 필터백(30)은 상단부가 튜브시트(14)와 스냅링(16)을 통해 고정되고 그 하단부는 아무런 고정수단이 없이 자유단으로 되어 있다.In addition, thefilter bag 30 has an upper end fixed through thetube sheet 14 and thesnap ring 16, and the lower end thereof is a free end without any fixing means.

그러나, 이러한 종래 기술의 여과집진장치는 필터백의 하단부가 고정되지 않은 자유단으로 마련되어 있기 때문에, 외부의 분진 유입 등의 풍향에 의해서만도 서로간의 마찰이나 부딪힘 등이 발생하여 필터백의 터지거나 손상이 발생하는 문제점이 있었고, 또한, 필터백이 계속해서 움직이는 상태로 필터링이 수행되기 때문에, 안정적인 필터링이 이루어지지 않게 되어 결과적으로 필터링 효율을 떨어지게 되는 등의 문제점을 갖고 있었다.However, since the filter bag of the prior art is provided with a free end at which the lower end of the filter bag is not fixed, friction or collision with each other occurs only by the wind direction such as external dust inflow, and thus the filter bag may burst or be damaged. In addition, since the filtering is performed while the filter bag is continuously moving, there is a problem that the filtering is not stable and the filtering efficiency is lowered as a result.

본 발명은 이러한 문제점을 해결하기 위해서 안출된 것으로서, 본체 내부의 자유단인 필터백의 하단부를 고정시킬 수 있도록 함으로써, 서로간의 마찰이나 부딪힘 등에 의해 필터백의 터지는 것을 방지함은 물론 필터백이 정지된 상태에서 안정적으로 분진을 필터링 할 수 있게 되어 결과적으로 필터링 효율을 향상시킬 수 있도록 하는 여과집진장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and by fixing the lower end of the filter bag, which is a free end inside the main body, to prevent the filter bags from bursting due to friction or bumping with each other, as well as the filter bag is stopped It is an object of the present invention to provide a bag filter which can stably filter dust and consequently improve the filtering efficiency.

이와 같이 상기 목적을 달성하기 위한 본 발명의 여과집진장치는 본체의 내부에 상단부가 고정되고 하단부가 자유단으로 된 복수의 필터백이 설치되는 여과집진장치에 있어서, 상기 필터백의 하단부를 고정시키기 위한 고정수단이 더 구비된 것을 특징으로 한다.As described above, the present invention provides a bag filter in which a plurality of filter bags having an upper end part and a lower end part of a free end part are installed in the main body, and fixed for fixing the lower part of the filter bag. Means is further provided.

또한, 본 발명에 따른 여과집진장치에 있어서, 상기 고정수단은, 상기 각각의 필터백의 저면을 떠받치는 저면받침부와, 필터백의 하단 외주면을 지지하는 외 면지지부로 이루어진 것이 바람직하다.In addition, in the bag filter according to the present invention, the fixing means is preferably composed of a bottom support portion for holding the bottom of each filter bag, and an outer surface support for supporting the outer peripheral surface of the lower end of the filter bag.

또한, 본 발명에 따른 여과집진장치에 있어서, 상기 저면받침부는 교차되는 십자형 봉 구조로 되고, 이에 대응되는 외면지지부는 상기 저면받침부의 각 단부에서 상방으로 일정길이 직립 연장되는 일체형 구조로 된 것이 바람직하다.In addition, in the filter bag according to the present invention, the bottom support portion is a cross-shaped rod structure that intersects, the outer support portion corresponding to it is preferably of an integral structure extending a predetermined length upright from each end of the bottom support portion.
