Description

난연성 필터 백(Filter Bag)과 그 제조방법Flame retardant filter bag and its manufacturing method

본 발명은 산업체에서 발생되는 먼지를 제거하기 위한 여과포 집진장치에서 사용하는 필터백(Filter Bag)과 그 제조방법에 관한 것으로, 보다 상세하게는 철강 또는 시멘트 공업 현장 등에서 분진 형태의 오염물을 포함한 배출공기를 정화시켜 정화된 공기만을 대기중으로 방출하게 하고, 여과포 집진장치에서 화재발생시 연소를 지연시킬 수 있는 난연성 필터백(Filter Bag)과 그 제조방법에 관한 것이다.The present invention relates to a filter bag (filter bag) used in the filter bag dust collector for removing dust generated in the industry and a method of manufacturing the same, more specifically, exhaust air containing dust-like contaminants in the steel or cement industry, etc. The present invention relates to a flame retardant filter bag capable of delaying combustion in the event of a fire in a filter bag dust collector and purifying only the purified air to the atmosphere.

일반적으로 철강 공업, 시멘트 공업 또는 분체를 원료로 하거나 분체 형태의 제품을 생산하는 공업 현장에서는 많은 공정에서 다량의 분진을 포함한 오염된 공기가 배출되게 되고 이와 같은 오염된 공기가 그대로 대기 중으로 배출될 때는 심각한 대기 오염을 초래할 수 있기 때문에 모든 업체에서는 오염된 공기를 정화하여 대기 중으로 방출하도록 의무화되어 있다.Generally, in the steel industry, cement industry, or industrial sites that use powder or produce powder-like products, many processes produce polluted air containing a large amount of dust, and when such polluted air is released into the atmosphere as it is, All companies are required to purify the polluted air and release it into the atmosphere because it can cause serious air pollution.

하지만, 상기와 같은 목적의 폐기물 소각로는 여과포집진장치에서 분진과 함께 유입되는 불꽃으로 인하여 필터백(filter bag)의 화재가 발생하여 생산공정이 중단되거나 장치의 수명저하 및 운전 유지비 증가, 주변기기의 화재 발생 위험 노출등 전체공정을 위협하는 사례가 자주 발생하는 등의 문제점이 있다.However, the waste incinerator for the above purpose is caused by the fire of the filter bag due to the flame introduced into the dust collector from the filter bag, the production process is interrupted or the life of the device decreases, operation maintenance costs increase, fire of peripheral equipment There are problems such as frequent occurrence of threats to the entire process, such as exposure risks.

또한, 국내 산업계에서는 중유연소보일러의 사용 증가로 분진의 발생량은 증가하고 중유보일러에서 발생하는 분진의 입자에는 중유성분이 다량 함유되어 있다는 문제점이 있다.In addition, there is a problem in the domestic industry that the generation of dust increases due to the increase in the use of heavy oil combustion boiler, and the particles of dust generated in the heavy oil boiler contains a large amount of heavy oil components.

상기와 같은 이유로 오염된 공기가 그대로 대기 중으로 배출될 때는 심각한 대기 오염을 초래할 수 있기 때문에 여과포집장치를 가진 폐기물 소각로를 건설하여 오염된 공기를 정화하여 왔다.For this reason, when the polluted air is discharged to the atmosphere as it is, it can cause serious air pollution. Therefore, a waste incinerator having a filter collecting device has been constructed to purify the polluted air.

이때 공기 정화 수단으로 채용되는 것중의 하나가 집진기용 백필터이며, 이 집진기용 백필터 내부에는 공기에 대한 필터링을 수행하는 긴 원형 또는 비원형의 백(Bag) 형태를 가진 필터백이 그 중심부에 장착되어 있다.At this time, one of the air purifying means is a bag filter for the dust collector, and inside the bag filter, a filter bag having a long circular or non-circular bag shape for filtering air is mounted at the center thereof. It is.

상기와 같이 이용되는 집진기용 백필터의 필터백이 갖추어야 할 성능으로는;As a performance of the filter bag of the bag filter for dust collector used as described above;

첫째, 통기성이 좋으면서도 공극이 미세하고 균일하게 공기만을 통기시키고 분진 등은 통과시키지 않는 고여과 성능을 지닌 필터백을 필요로 한다.First, there is a need for a filter bag having a high filtration performance that is well ventilated but finely ventilates and uniformly vents only air and does not allow dust to pass through.

이와 같은 요구에 가장 부응하는 것이 부직포라고 할 수 있으며 그 때문에 부직포가 필터백의 소재로 많이 사용되고 있다.It can be said that the most non-woven fabric that meets these requirements is that non-woven fabric is widely used as a material for filter bags.

둘째, 집진기가 채용되는 대부분의 공업공정이 고온에서 수행되고 소각이나 수지 또는 금속을 용융함으로써 화염을 동반하는 경우가 많기 때문에 고내열성 및 난연성이 요구된다.Secondly, since most industrial processes employing dust collectors are carried out at high temperatures and are often accompanied by flames by incineration or melting of resins or metals, high heat resistance and flame resistance are required.

기타, 특수한 경우에 투습성 또는 방수. 발수성이 요구되기도 한다.Other, breathable or waterproof in special cases. Water repellency may be required.

상기한 바와 같이 요구사항을 만족하기 위한 필터백으로서 부직포가 많이 이용되는데 이와 같은 필터백용 부직포는 단면 구조를 볼 때 단일의 부직포로 이루어지기 보다는 직포를 포함한 다층의 중첩물로 되어 있다.As described above, a nonwoven fabric is widely used as a filter bag to satisfy the requirements. Such a filter bag nonwoven fabric is composed of a multi-layer superposition including a woven fabric rather than a single nonwoven fabric in cross-sectional structure.

종래의 필터백의 단면구조의 일예인 도 2를 참조하여 필터백의 층구성을 설명하면 부직포로 된 제1층(21)과 제3층(23) 사이에 강력 보강을 위하여 직물로 된 제2층(22)이 개재되어 있는 형태이다.Referring to FIG. 2, which is an example of a cross-sectional structure of a conventional filter bag, a layer structure of the filter bag will be described. A second layer made of a fabric for strong reinforcement between the first layer 21 and the third layer 23 made of nonwoven fabric ( 22) is intervened.

그러나, 이와 같은 종래의 백필터에 있어서는 난연성에 있어서 많이 미달하여서 종종 화재의 원인이 되었기 때문에 고난연성을 요하는 용도에는 사용할 수 없는 문제점이 있었다.However, such a conventional bag filter has a problem that it cannot be used for applications requiring high flame retardancy because it is much less flame retardant and often causes a fire.

이와 같은 문제점을 해결하기 위하여 상기 제1층(21)위에 수지와 내열성이 우수한 분체 카본의 혼합물을 코팅하여 사용하기도 하였으나 그에 의해 내열 난연성은 어느 정도 해소 되었다고 하여도 대신에 통기성이 현저히 떨어지는 문제점이 발생하였다.In order to solve this problem, a mixture of resin and powder carbon having excellent heat resistance was coated on the first layer 21, but there was a problem that the breathability was remarkably inferior even though the heat flame retardance was solved to some extent. It was.

또한, 난연성, 특히 고온 스파크에 의한 내화성을 증가시키기 위해 함진 공기와 1차로 접촉하게 되는 필터백의 외표면에 폴리 페닐렌 렐레프탈아미드 섬유의 얇은 부직포가 니들링되어 있는 폴리페닐렌 이소프탈아이드, 폴리에스테르 또는 폴리페닐렌 설파이드 섬유의 펠트 적층체를 부가시킨 것이 대한민국 특허출원 공개번호 제94-703223호에 개시되어 있으나, 특수 섬유 소재를 채용함으로써 경제성이 떨어지고, 포의 형태 안정성이 개선되지 못한 것이었다.In addition, polyphenylene isophthalide in which a thin nonwoven fabric of polyphenylene relephthalamide fibers is needled on the outer surface of the filter bag which is in primary contact with the impregnated air to increase flame retardancy, in particular, fire resistance by high temperature sparks, The addition of felt laminates of polyester or polyphenylene sulfide fibers is disclosed in Korean Patent Application Publication No. 94-703223, but the use of a special fiber material was not economical and the form stability of the fabric was not improved. .
