Description

이온교환수지를 이용한 케미컬 필터여재{chemical filter using ion exchange resin}Chemical filter using ion exchange resin

본 발명은 반도체 또는 일반 산업분야 등이나 공공장소, 특히 대기 오염에 노출되어 있는 산업현장으로부터 유해가스를 제거하기 위해 사용되고 있는 케미컬 필터 여재에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to chemical filter media that are used to remove harmful gases from semiconductors, general industrial fields, or public places, particularly industrial sites that are exposed to air pollution.

대기오염에 노출된 장소로부터 유해가스 제거를 위해 사용되고 있는 케미컬 필터로는 V형, 평판형, tray 형태의 케미컬 필터, ACF(Active Carbon Fiber) 또는 이온교환부직포를 이용한 케미컬 필터 등이 있다. V형, 평판형, tray 형태와 같은 형태의 케미컬 필터는 투입되는 첨착활성탄의 양이 많이 소요되기 때문에 고 농도의 유해가스 포집에 유리하며 유해가스 포집량이 많은 반면 압력손실이 크다는 단점이 있으며 ACF(Active Carbon Fiber) 또는 이온교환부직포 형태의 필터는 저 농도의 유해가스 포집에 유리하고, 압력손실이 적고, 무게가 가볍다는 장점을 가지는 반면 유해가스 포집량이 첨착활성탄을 이용한 케미컬 필터에 비해 낮고, 가격이 비싸다는 단점이 있다. 따라서 압력손실이 최소화하면서 유해가스의 흡착량이 우수한 케미컬 필터의 개발이 시급하다.Chemical filters that are used to remove harmful gases from air pollution exposed areas include V-type, flat-type, tray-type chemical filters, chemical filters using ACF (active carbon fiber) or ion exchange nonwoven fabrics. Chemical filters in the form of V-type, flat-type, tray type are advantageous for high concentration of harmful gas collection because of the high amount of impregnated activated carbon that is added. Active Carbon Fiber) or ion exchange nonwoven type filters have the advantage of low concentration of harmful gas capture, low pressure loss and light weight, while low harmful gas collection compared to chemical filters using impregnated activated carbon. This is expensive. Therefore, it is urgent to develop a chemical filter having a high adsorption amount of harmful gas while minimizing pressure loss.

첨착활성탄을 이용한 유해가스의 흡착은 흡착제의 표면과 흡착질이 물리적 또는 화학적인 인력에 의하여 결합하는 현상으로 혼합된 흡착질에서 일정 성분을 선택적으로 분리 또는 정제하는데 이용되는 기술로서 대기 및 수질오염물질의 제거, 휘발성 용제의 회수, 혼합물의 분리 및 정제 등에 광범위하게 이용되고 있다. 이러한 첨착활성탄은 일반활성탄에 비해 유해가스의 흡착성능은 우수하지만 압력손실이 높고, 2차로 분진이 발생한다는 문제가 있다.Adsorption of harmful gases using impregnated activated carbon is a technique used to selectively separate or purify certain components from the adsorbate mixed with the adsorbent surface and adsorbate by physical or chemical attraction, and remove air and water pollutants. It is widely used for recovery of volatile solvents, separation and purification of mixtures. The impregnated activated carbon has a problem that adsorption performance of harmful gases is superior to that of ordinary activated carbon, but pressure loss is high and secondary dust is generated.

이온교환부직포는 이온교환방식에 의해 유해가스를 제거하는 방식으로, 이온교환부직포는 폴리올레핀 섬유에 전자빔이나 방사선을 조사하여 섬유 주 사슬에 라디칼을 생성시킨 후 폴리스티렌을 그라프팅한 다음 황산 또는 인산 등 제거하고자 하는 극성가스에 따라 여러 가지 종류의 기능화 반응을 거쳐서 제조된다. 이온교환부직포는 첨착활성탄에 비해 유해가스 제거성능은 떨어지지만 2차 유해물질이 발생하지 않고, 압력손실이 낮다는 장점이 있지만 제조비용이 높다는 단점이 있다.Ion-exchange nonwoven fabrics remove harmful gases by ion-exchange method.Ion-exchange nonwoven fabrics irradiate polyolefin fibers with electron beam or radiation to generate radicals in the fiber main chain, and then grafting polystyrene and then removing sulfuric acid or phosphoric acid Depending on the polar gas to be prepared through various kinds of functionalization reaction. The ion exchange nonwoven fabric has the disadvantage of lowering the harmful gas removal performance compared to the impregnated activated carbon, but does not generate secondary harmful substances and has a low pressure loss, but has a disadvantage of high manufacturing cost.

본 발명자에 의해 출원된 특허(출원번호 : 제 11201호, 출원일 : 2000.3.7)에 의하면 바인더를 이용하여 첨착활성탄을 금속 망체에 부착시키면 압력손실은 해결되지만 케미컬 필터의 사용수명이 짧아지는 단점이 있다. 이를 보완하기 위하여 본 발명자에 의해서 출원된 실용신안 (출원번호 : 제13759호, 출원일 : 2000. 5.16)에서는 유해가스 제거매체로서 첨착활성탄과 이온교환부직포를 사용하기 때문에 유해가스의 제거량이 크고, 고농도의 가스에 적용이 가능할 뿐만 아니라 압력손실이 적게 걸린다는 장점이 있지만 고가의 이온교환부직포를 사용하기 때문에 첨착활성탄을 사용하는 경우 보다 비용이 높아진다는 단점이 있다.According to a patent filed by the present inventor (application number: 11201, filed date: 2000.3.7), if the impregnated activated carbon is attached to the metal mesh by using a binder, the pressure loss is solved, but the service life of the chemical filter is shortened. have. In order to compensate for this, the utility model filed by the present inventors (Application No .: 13759, filed on May 16, 2000) uses an impregnated activated carbon and an ion exchange nonwoven fabric as a medium for removing harmful gases. It is not only applicable to the gas but also has the advantage of low pressure loss, but the use of expensive ion exchange nonwoven fabric has the disadvantage of higher cost than using impregnated activated carbon.

본 발명은 반도체 산업 또는 일반 산업 분야 등이나 공공장소, 특히 대기오염에 노출되어 있는 산업현장으로부터 유해가스를 제거하기 위해 사용되고 있는 케미컬 필터의 유해가스 제거효율을 증가시키고, 압력손실을 최소화하며, 케미컬 필터의 무게를 감소시키고, 운전비용을 절감시키는데 목적이 있다.The present invention increases the efficiency of removing harmful gases from chemical filters used to remove harmful gases from the semiconductor industry or general industrial fields or from public places, especially industrial sites exposed to air pollution, minimizes pressure loss, and The purpose is to reduce the weight of the filter and reduce the running cost.

본 발명에서는 첨착활성탄에 비해 유해가스 제거성능이 우수한 이온교환수지를 이용하여 본 발명자가 이미 출원한 방법 (출원번호 : 제 11201호, 출원일 : 2000.3.7) 으로 금속 망체에 첨착활성탄과 이온교환수지를 부착하였고, 부착된 이온교환수지와 첨착활성탄을 혼합하여 사용하였다. 이러한 방법으로 제조된 케미컬 필터는 첨착활성탄에 비해 유해가스 흡착성능은 우수하며, 압력손실은 낮아지며, 이온교환부직포를 사용하여 제작된 케미컬 필터에 비해 가격도 저렴하다는 장점을 가지고 있다.In the present invention, the method of the present inventors has already applied using the ion exchange resin excellent in removing harmful gases compared with the impregnated activated carbon (application number: 11201, filed date: 2000.3.7) impregnated activated carbon and ion exchange resin in the metal mesh Was attached, and the attached ion exchange resin and the impregnated activated carbon were mixed and used. The chemical filter manufactured in this way has the advantage of better adsorption of harmful gases, lower pressure loss, and lower price than chemical filters manufactured using ion-exchange nonwoven fabrics.

본 발명에 의한 케미컬 필터 여재에서의 압력손실 및 흡착성능은 이온교환수지를 금속 망체에 부착시킴으로서 달성된다. 또한 이온교환수지는 첨착활성탄에 비해 흡착성능이 우수하며, 이러한 이온교환수지를 금속 망체에 부착시킴으로서 압력손실이 적게 걸리고, 이온교환부직포에 비해 가격이 저렴하다는 장점이 있다.Pressure loss and adsorption performance in the chemical filter media according to the present invention is achieved by attaching the ion exchange resin to the metal mesh. In addition, the ion exchange resin has better adsorption performance than the impregnated activated carbon, and by attaching the ion exchange resin to the metal mesh, the pressure loss is reduced, and the price is lower than that of the ion exchange nonwoven fabric.

본 발명은 유해가스를 처리하는 케미컬 필터에 있어서 반도체 산업 또는 일반 산업 분야 등에서 유해가스의 제거 효율을 증가시키며, 압력손실을 최소화하며, 케미컬 필터의 무게를 감소시키는 방법에 관한 것이다.The present invention relates to a method of increasing the removal efficiency of harmful gases, minimizing pressure loss, and reducing the weight of the chemical filter in the chemical filter for treating harmful gases in the semiconductor industry or general industrial fields.

본 발명에서는 유해가스의 제거 효율을 증가시키기 위하여 기존에 수처리용으로 사용되어지고 있는 이온교환수지를 화학 처리하여 유해가스를 흡착할 수 있게제조한 후 이온교환수지의 입경이 작기 때문에 이온교환수지 자체로는 사용이 어려워 본 발명자가 특허 출원한 방법(출원번호 : 제 11201호, 출원일 : 2000.3.7)과 동일하게 금속 망체에 첨착활성탄 대신에 이온교환수지를 부착시켜 케미컬 필터 여재를 제조하고 이를 이용하여 극성 유해가스를 제거하는 방법이다.In the present invention, in order to increase the removal efficiency of the harmful gas, the ion exchange resin, which has been used for water treatment, is chemically treated to produce harmful gas and then the ion exchange resin itself has a small particle diameter. It is difficult to use a furnace, and the chemical filter media is prepared by attaching ion exchange resins to metal meshes instead of impregnated activated carbon in the same manner as the method of the present inventors applying for the patent (Application No. 11201, filed date: 2000.3.7). It is a method to remove polar harmful gas.

이하 본 발명에 따른 유해가스 제거 효율을 증가시키기 위한 케미컬 필터 여재의 실시예를 첨부도면에 의거하여 설명하면 다음과 같다.Hereinafter, an embodiment of the chemical filter medium for increasing the toxic gas removal efficiency according to the present invention will be described based on the accompanying drawings.

실시예Example

극성유해가스 제거에 사용되고 있는 케미컬 필터 여재(1)는 제거 효율을 증가시키기 위하여 본 발명자가 이미 출원한 방법(출원번호 : 제 11201호, 출원일 : 2000.3.7)으로 사용되고 있는 첨착활성탄이나 이온교환부직포 대신에 이온교환수지(2)를 사용하였다. 여기에 사용되는 이온교환수지(2)는 기존에 일반적으로 사용되고 있는 정수처리용 이온교환수지인데 극성 유해가스의 종류에 따라 양이온교환수지와 음이온교환수지를 사용한다. 이러한 이온교환수지(2)를 처리하는 방법으로 음이온 또는 양이온 교환수지를 준비한 후 산성 또는 염기성 용액을 사용하여 약 하루 정도 함침시킨다. 함침이 끝난 이온교환수지(2)는 필터에 의해 용액과 이온교환수지(2)를 분리한 후, 건조기에서 이온교환수지(2)가 변형이 되지 않는 온도인 약 80℃의 온도에서 건조시킨다.The chemical filter media (1) used for the removal of polar harmful gas is an impregnated activated carbon or ion exchange nonwoven fabric which is used in the method (application number: 11201, application date: 2000.3.7) already filed by the present inventor to increase the removal efficiency. Instead, an ion exchange resin (2) was used. The ion exchange resin (2) used here is an ion exchange resin for water treatment generally used conventionally, and uses a cation exchange resin and an anion exchange resin depending on the type of polar harmful gas. After the anion or cation exchange resin is prepared by the method of treating such an ion exchange resin (2), it is impregnated for about one day using an acidic or basic solution. After the impregnated ion exchange resin (2) is separated from the solution and the ion exchange resin (2) by a filter, the ion exchange resin (2) is dried at a temperature of about 80 deg. C, which is a temperature at which the ion exchange resin (2) is not deformed in a dryer.

위와 같은 방법으로 제조된 이온교환수지(2)는 입경이 작아 공기가 케미컬 필터(3)를 통과하면 압력손실이 많이 발생하기 때문에 실제적으로 유해가스를 제거하는 목적으로 사용되는 것이 불가능하므로 압력손실을 가장 최소화하기 위하여 본 발명자 출원한 방법에 의해 금속 망체(4)에 이온교환수지(2)를 부착하여 사용하였으며, 케미컬 필터 여재(1)를 제작할 때에는 금속 망체(4)에 부착된 이온교환수지(2) 양쪽에 부직포를 부착하여 사용하였다.Since the ion exchange resin (2) prepared in the above method has a small particle size and air passes through the chemical filter (3), pressure loss occurs a lot, so it is impossible to actually use it to remove harmful gases. In order to minimize the ion-exchange resin (2) was attached to the metal mesh 4 by the method of the present inventors, the ion-exchange resin attached to the metal mesh 4 when manufacturing the chemical filter media (1) ( 2) Nonwoven fabric was attached to both sides and used.

케미컬 필터 여재(1)로 금속 망체(4)에 부착된 이온교환수지(2)에 대한 극성 유해가스 제거실험을 수행하였다. 화학 처리된 이온교환수지(2)로 제조된 케미컬 필터 여재의 극성 유해가스 제거성능을 비교하기 위하여 일반활성탄, 첨착활성탄(5), 이온교환부직포(6)로 제조된 케미컬 필터 여재(1)를 사용하여 비교하였다. 대표적인 염기성 가스로 암모니아 가스를 선택하여 실험을 수행하였고, 실험방법으로는 케미컬 필터 여재(1)를 실험 칼럼에 고정시키고, 일정한 유량을 지속적으로 흘려주면서 입구와 출구의 농도를 측정하여 케미컬 필터 여재(1)의 제거 성능을 확인하였다. 표 1에 케미컬 필터 여재(1)의 제거 성능 실험조건을 나타내었다.A polar harmful gas removal experiment was performed on the ion exchange resin (2) attached to the metal mesh (4) with the chemical filter media (1). Chemical filter media (1) made of ordinary activated carbon, impregnated activated carbon (5), and ion exchange nonwoven fabric (6) was used to compare the polar harmful gas removal performance of chemical filter media prepared with chemically treated ion exchange resin (2). Comparison was made using. The experiment was carried out by selecting ammonia gas as a representative basic gas, and the experimental method was to fix the chemical filter media (1) to the experimental column and measure the concentration of the inlet and the outlet while continuously flowing a constant flow rate. The removal performance of 1) was confirmed. Table 1 shows the experimental conditions for the removal performance of the chemical filter media (1).

또한 각각의 케미컬 필터 여재(1)에 대해서 유기물의 제거 성능을 확인하였으며, 유기물의 제거성능을 확인하기 위해서 톨루엔을 사용하여 각각의 케미컬 필터 여재(1)에 대하여 시험을 수행하였다. 시험 방법으로는 각각을 케미컬 필터 여재(1)로 만든 다음 유량 : 5 L/min, Column dia. : 45 mm, 톨루엔 농도 : 300 ppm을 맞춘 후 제거 시험을 하였다. 그림 2는 톨루엔에 대한 제거성능을 나타낸 그림이고, 그림 2에서 보는 바와 같이 첨착활성탄(5) 또는 일반활성탄을 이용한 케미컬 필터 여재(1)는 톨루엔을 제거할 수 있지만, 그 외의 케미컬 필터 여재(1)에 대해서는 유기물이 전혀 제거되지 않는 것을 볼 수 있다.In addition, the removal performance of the organic material was confirmed for each chemical filter medium (1), and the test was performed on each chemical filter medium (1) using toluene to confirm the removal performance of the organic material. Test methods were each made of chemical filter media (1) and then flow rate: 5 L / min, Column dia. : 45 mm, toluene concentration: 300 ppm, after adjusting the removal test. Figure 2 shows the removal performance of toluene. As shown in Figure 2, chemical filter media using impregnated activated carbon (5) or ordinary activated carbon (1) can remove toluene, but other chemical filter media (1) For), it can be seen that organic matter is not removed at all.

위 실험 결과를 바탕으로 하여 금속 망체(4)에 이온교환수지(2)를 부착한 케미컬 필터 여재(1)를 이용하여 케미컬 필터(3)를 제작하면 흡착성능이 증가하며, 압력손실이 낮아지며, 무게가 가벼워 비용이 절감된다. 또한 금속 망체(4)에 부착시킨 이온교환수지(2)를 사용할 때 이온교환수지(2) 양쪽에 이온교환수지(2)가 유동이 생기지 않도록 하기 위하여 압력손실이 거의 없는 부직포를 사용하여 고정시키고 있지만, 일반부직포 대신에 이온교환부직포(6)를 조합하여 사용하게 되면 유해가스 제거효율은 더욱 증가하게 될 뿐만 아니라 각각의 장점을 이용한 첨착활성탄(5)과, 이온교환부직포(6), 이온교환수지(2)를 조합하여 사용하게 되면 특정가스에 대하여 흡착성능이 우수하며, 압력손실은 낮아지며, 또한 유기물을 동시에 제거가 가능하다. 표 3에 조합된 케미컬 필터 여재(1)의 제거 성능을 나타내었다. 그림 3에 각각의 여재를 조합한 형태의 케미컬 필터 여재(1)와 단일 형태의 케미컬 필터 여재(1)의 제거성능을 나타내었다. 그림 3에서 보는 바와 같이 조합한 형태의 케미컬 필터 여재(1)의 암모니아 제거성능이 단일 형태의 케미컬 필터 여재(1) 보다 2배이상 우수한 제거 성능을 나타내는 것을 볼 수 있다.Based on the above experimental results, when the chemical filter (3) is manufactured using the chemical filter media (1) having the ion exchange resin (2) attached to the metal mesh (4), the adsorption performance is increased, and the pressure loss is lowered. Light weight saves money. In addition, when using the ion exchange resin (2) attached to the metal mesh (4), in order to prevent the flow of the ion exchange resin (2) on both sides of the ion exchange resin (2) fixed by using a non-woven fabric with almost no pressure loss However, when the ion exchange nonwoven fabric 6 is used instead of the general nonwoven fabric, the harmful gas removal efficiency is further increased, and the impregnated activated carbon 5, the ion exchange nonwoven fabric 6, and the ion exchange using the respective advantages are further increased. When the resin (2) is used in combination, the adsorption performance is excellent for a particular gas, the pressure loss is low, and organic matters can be removed at the same time. The removal performance of the chemical filter media 1 combined in Table 3 is shown. Figure 3 shows the removal performance of the chemical filter media (1) and the single type of chemical filter media (1). As shown in Figure 3, it can be seen that the ammonia removal performance of the combined chemical filter media (1) is two times better than that of the single chemical filter media (1).

본 발명은 기존에 사용하고 있는 첨착활성탄에 비해 흡착성능이 우수한 흡착제를 사용하므로 장기간 사용이 가능하므로 흡착제의 교체 주기를 연장하여 폐 흡착제의 발생으로 인한 폐기물의 양을 감소할 수 있을 뿐만 아니라 2차 유해물질이 발생하지 않으므로 케미컬 필터에 적용이 가능하다. 또한 첨착활성탄에 비해 흡착성능이 우수한 이온교환수지를 사용하여 유해가스에 의한 대기오염을 억제할 수 있다.Since the present invention uses an adsorbent that has superior adsorption performance compared to the impregnated activated carbon, it can be used for a long time, so the replacement cycle of the adsorbent can be extended to reduce the amount of waste due to the generation of the waste adsorbent as well as the secondary. Since no harmful substances are generated, it can be applied to chemical filters. In addition, it is possible to suppress air pollution due to harmful gases by using an ion exchange resin having excellent adsorption performance compared to impregnated activated carbon.
