본 발명은 일반산업 분야나 공공장소, 특히 대기 오염에 노출되어 있는 산업현장으로부터 유해가스를 제거하기 위해 사용되고 있는 에어필터에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air filter used to remove noxious gases from general industrial fields or public places, especially industrial sites that are exposed to air pollution.

일반산업 분야나 대기 오염물질은 입자상 분진과 가스상 물질로 분류되고 가스상의 오염 물질을 효과적으로 제거하기 위해서는 첨착활성탄을 사용한 에어필터가 필요하다. 일반적으로 활성탄 에어필터는 활성탄 층을 통과하는 공기에 의해 발생되는 압력손실이 커서 유속감소율이 크게 발생한다는 단점을 가지고 있다. 기존에 대기오염에 노출된 장소로부터 유해가스 제거를 위해 사용되고 있는 에어필터로는 V형 bed, 평 bed, tray 형태의 에어필터, ACF를 이용한 에어필터, 활성탄을 파쇄하여 바인더와 결합한 에어필터 등이 있다. V형 bed와 같은 형태의 에어필터는 투입되는 활성탄의 양이 많기 때문에 고농도의 가스 포집에 유리하며 유해가스 포집량이 많은 반면 압력손실이 큰 단점이 있으며, ACF 형태의 에어필터는 저농도의 가스 포집에 유리하고 차압이 적게 걸리는 반면 가스 포집량이 활성탄을 이용한 에어필터에 비해 낮고, 가격이 비싸다는 단점을 가지고 있다. 따라서 압력손실을 최소화해야 하는 공정에서는 유지비용이 높고 유해가스 포집효율이 낮은 ACF 형태의 에어필터의 적용이 불가피한 문제점을 가지고 있다.기 출원된 국내 특허 제 94-1924호에서는 폴리 에스텔 여재를 사용하여 활성탄을 부착하여 사용하고 있는데, 여기서 사용되는 폴리에스텔 여재의 종류는 부직포 또는 직포이다. 본 발명에서 사용되고 있는 여재의 종류는 부직포나 직포가 아닌 망체로서 가로와 세로의 크기가 0.8-1.2mm의 구멍이 존재하는 망을 사용하며, 여기에 사용되는 첨착활성탄은 0.25-0.6mm의 크기를 부착하여 사용하기 때문에 압력손실을 최소화 할 수 있으며, 제거효율 및 성능이 향상된다.General industrial fields or air pollutants are classified into particulate dust and gaseous substances, and an air filter using impregnated activated carbon is required to effectively remove gaseous pollutants. In general, activated carbon air filters have a disadvantage in that a large flow rate decrease occurs due to a large pressure loss generated by the air passing through the activated carbon layer. Existing air filters used to remove harmful gases from places exposed to air pollution include V-type beds, flat beds, tray-type air filters, air filters using ACF, and air filters that combine activated carbon with binders. have. The air filter of V-type bed has the disadvantage of high concentration of activated carbon and high harmful gas collection and high pressure loss due to the large amount of activated carbon. The ACF type air filter has a low concentration of gas. It has the disadvantage of being advantageous and having a low differential pressure, but having a lower gas collection amount and a higher price than an air filter using activated carbon. Therefore, in the process of minimizing pressure loss, it is inevitable to apply an ACF type air filter with high maintenance cost and low harmful gas collection efficiency. In Korea Patent No. 94-1924, a polyester filter is used. Activated carbon is attached and used, and the type of polyester media used here is nonwoven fabric or woven fabric. The type of media used in the present invention is a non-woven fabric or a non-woven fabric, which uses a mesh having holes of 0.8-1.2 mm in width and length, and the impregnated activated carbon used herein has a size of 0.25-0.6 mm. As it is attached and used, pressure loss can be minimized and removal efficiency and performance are improved.

본 발명은 유해가스 포집매체로서 첨착활성탄을 사용하기 때문에 유해가스의포집량이 크고, 고농도의 가스에 적용이 가능할 뿐만 아니라, 폴리에틸렌 또는 알루미늄과 같은 금속 망체에 첨착활성탄 입자를 첨착활성탄의 성능에 영향을 주지 않는 바인더를 이용하여 망체에 고르게 부착시키기 때문에 압력손실이 적다는 장점이 있다. 또한 필터 지지체가 유연하기 때문에 평판형, 지그재그형, 관형 등으로 필터를 자유롭게 제작할 수 있다는 장점을 가지고 있다.In the present invention, since the impregnated activated carbon is used as a hazardous gas trapping medium, the amount of harmful gases is large and it is not only applicable to a high concentration of gas. There is an advantage that the pressure loss is small because evenly attached to the net using a binder that does not give. In addition, since the filter support is flexible, the filter can be freely manufactured in a flat plate shape, a zigzag shape, a tubular shape, and the like.

본 발명은 상기와 같은 방법으로 이루어진 것이다. 본 발명은 일반산업 분야나 공공장소, 특히 대기 오염에 노출되어 있는 산업현장으로부터 유해가스를 제거하기 위해 사용되고 있는 에어필터의 유해가스 포집효율을 증가시키고, 에어필터 전단에 걸리는 압력손실을 감소시키는데 그 목적이 있다. 부가적인 효과로서는 압력손실의 저하에 따른 동력비 절감을 가져올 수 있다.The present invention is made in the above manner. The present invention is to increase the harmful gas collection efficiency of the air filter used to remove the harmful gas from general industrial fields or public places, especially industrial sites exposed to air pollution, and to reduce the pressure loss applied to the air filter front end. There is a purpose. As an additional effect, it can bring about a reduction in power costs due to a drop in pressure loss.

본 발명에 의한 에어필터에서의 유해가스 포집 능력은 첨착활성탄을 사용함으로써 달성된다.The harmful gas collection capability in the air filter according to the present invention is achieved by using impregnated activated carbon.

본 발명에 의한 에어필터에서의 압력손실은 폴리에틸렌 망체나 알루미늄과 같은 금속 망체를 지지체로 사용함으로써 최소화시킬 수 있다.Pressure loss in the air filter according to the present invention can be minimized by using a metal mesh such as polyethylene mesh or aluminum as a support.

본 발명에 의한 에어필터는 압력손실의 영향을 최소화할 수 있도록 폴리에틸렌 망체 또는 금속 망체를 지지체로 사용하고, 첨착활성탄의 성능에 영향을 주지 않는 바인더를 도포하여 첨착활성탄을 부착시킨 필터 여재를 이용하여 제작한다. 또한 지지체가 유연성을 가지므로 에어필터 제작시에 필터 여재를 평판형, 지그재그형 또는 관형으로 제작하도록 하는데 부차적인 목적이 있다.The air filter according to the present invention uses a polyethylene mesh or a metal mesh as a support so as to minimize the effect of pressure loss, and by applying a filter medium attached to the impregnated activated carbon by applying a binder that does not affect the performance of the impregnated activated carbon. To make. In addition, since the support has flexibility, there is a secondary purpose to fabricate the filter media in a flat, zigzag, or tubular shape when manufacturing the air filter.

이하, 본 발명에 따른 유해가스 제거를 위한 에어필터의 구성과 그 작용에 대한 실시예를 첨부 도면에 의거하여 상세하게 설명하면 다음과 같다.Hereinafter, an embodiment of the configuration of the air filter for removing the harmful gas according to the present invention and its operation will be described in detail with reference to the accompanying drawings.

실시예Example

유해가스 제거에 사용된 활성탄 에어필터(1)는 지지체인 폴리에틸렌 또는 금속 망체(2), 폴리우레탄 또는 실리콘 바인더(3), 흡착 매체인 첨착활성탄(4), 부착된 첨착활성탄(4)의 유동을 방지하기 위한 부직포(5), 필터를 고정하기 위한 알루미늄 판(6)으로 구성되어 있다.Activated carbon air filter (1) used to remove the noxious gas is a flow of polyethylene or metal mesh (2) as a support, polyurethane or silicon binder (3), impregnated activated carbon (4) and adsorbed activated carbon (4) as adsorption medium. It consists of a nonwoven fabric 5 for preventing the damage, and an aluminum plate 6 for fixing the filter.

제작 방법으로는 폴리에틸렌 망체(2)를 지지체로 사용하고, 이 망체(2)에 폴리우레탄 바인더(3)를 도포한 후, 1mm 크기의 첨착활성탄(4)을 폴리에틸렌 망체(2)에 부착시키고 첨착활성탄(4) 입자를 폴리에틸렌 망체(2)에 완전히 부착시키기 위해 85℃의 오븐에서 3시간 이상 건조하였다. 건조된 필터는 부착된 첨착활성탄(4)의 유동을 방지하기 위해 필터 상부와 하부를 부직포(5)로 감싼 후, 이를 알루미늄판(6)으로 고정시켰으며, 고정된 필터의 접촉면적을 증가시키기 위해 지그재그 형태(7)로 절곡하여 압력손실이 최소화되도록 하였다.As a production method, a polyethylene net body 2 is used as a support, and a polyurethane binder 3 is applied to the net body 2, and then an impregnated activated carbon 4 having a size of 1 mm is attached to the polyethylene net body 2 and attached. The activated carbon 4 particles were dried in an oven at 85 ° C. for at least 3 hours to completely adhere to the polyethylene network 2. The dried filter was wrapped with a nonwoven fabric 5 around the top and bottom of the filter to prevent the flow of the impregnated activated carbon 4, and then fixed with an aluminum plate 6 to increase the contact area of the fixed filter. It was bent in a zigzag shape (7) to minimize the pressure loss.

상기의 방법에 의해 에어필터(1)를 제작한 후, 유해가스에 대한 에어필터의 성능시험 결과를 표 1에 나타내었다. 유해가스의 모델로서 오존가스를 선택하여 선속도 0.2m/sec, 농도 200ppm의 조건 하에서, 각 에어필터의 두께와 압력손실이 대등하도록 하여 에어필터의 성능을 시험하였다. 각 에어필터의 성능은 에어필터를 통과하는 가스가 90% 흡착효율(C/C0= 0.1)로 제거되었을 때를 파과시점으로 보았다. 그 결과 ACF 에어필터에 비해 일반활성탄을 이용한 에어필터의 성능은 5배 증가 하였으며, 첨착활성탄을 이용한 에어필터의 성능은 10배 증가하였다. 이로써 본 발명에 의한 에어필터는 낮은 압력손실을 갖는 ACF 에어필터의 장점과 높은 가스제거효율을 갖는 활성탄 필터의 장점을 동시에 만족하는 에어필터라고 할 수 있다.After preparing the air filter 1 by the above method, the results of the performance test of the air filter for harmful gases are shown in Table 1. Ozone gas was selected as a model of the noxious gas, and the performance of the air filter was tested so that the thickness and pressure loss of each air filter were equal under the conditions of a linear velocity of 0.2 m / sec and a concentration of 200 ppm. The performance of each air filter was viewed as a breakthrough point when the gas passing through the air filter was removed at 90% adsorption efficiency (C / C 0 = 0.1). As a result, the performance of the air filter using the activated carbon is five times higher than that of the ACF air filter, and the performance of the air filter using the impregnated activated carbon is increased by 10 times. Accordingly, the air filter according to the present invention may be said to satisfy the advantages of the ACF air filter having a low pressure loss and the advantage of the activated carbon filter having a high gas removal efficiency.
