Description

세라믹 멀티-튜브 필터의 제조 방법{the manufacturing method of the ceramic multi-tube filter}The manufacturing method of the ceramic multi-tube filter

지난 10년간 지속적으로 증가추세에 있는 처리비용과 엄격해진 환경기준에 직면하여 폐기물관리를 위한 전통적인 종말처리접근방식은 매력을 잃게 되고 "폐기물 최소화", "폐기물 원천감소", "오염방지"등으로 다양하게 알려진 환경일치전략에 두드러진 관심을 끌고 있다.In the face of the ever-increasing treatment costs and stricter environmental standards over the past decade, traditional end-of-life approaches to waste management have become unattractive and have been reduced to "waste minimization", "waste source reduction" and "pollution prevention. Attention is drawn to various known environmental matching strategies.

이 전략의 기본적 전제는 폐기물이나 오염물의 발생을 원천적으로 피하는 것이나, 이는 설치비용의 증가와 관리상의 문제점이 있다.The basic premise of this strategy is to avoid the generation of wastes or contaminants at the source, but this leads to increased installation costs and management problems.

발생된 폐기물이나 오염물을 효과적으로 처리하는데 보다 능률적이고 경제적으로 처리하는, 다공성을 부여한 세라믹 멀티-튜브 필터를 발명한 것이다.Invented is a porous multi-tube filter with a porosity that is more efficient and economical for effectively treating the generated waste or contaminants.

본 발명은 기존의 분진 포집 규제에서 점차 폐가스 처리 문제로 대두되어지는 문제점들을 고온·고압에서 사용할 수 있고 여과 면적을 최대로 할 수 있는 새로운 필터를 개발하는 데에 그 목적이 있다.An object of the present invention is to develop a new filter that can be used at high temperature and high pressure, and problems that are gradually raised as a waste gas treatment problem in the existing dust collection regulation and maximize the filtration area.

환경문제로 대두되고 있는 자동차의 매연이나 공장에서 나오는 높은 온도의 부유물을 보다 효과적으로 여과시키고 생산라인에서 발생하는 불가피한 오염원중의 하나인 입자상 물질을 효과적으로 여과함으로써 대기 오염의 문제를 경제적이고 효과적으로 줄일 수 있는 효과를 가지고 있다.It is possible to effectively and efficiently reduce the problem of air pollution by effectively filtering the high temperature suspended solids from automobiles or factories that are emerging as environmental problems and particulate matter, which is one of the inevitable sources of pollution from production lines. Has an effect.

기존의 필터는 고온·고압에서 필터의 기능이 감소되고 또 파손 및 균열의우려가 있으나, 다공성을 부여한 세라믹 멀티 - 튜브 필터는 고온·고압에서도 필터의 기능이 감소되지 않고, 수명 또한 기존의 필터보다 우수하다는 것이다.Conventional filters have reduced filter function at high temperature and high pressure, and may cause breakage and cracking. However, ceramic multi-tube filters with high porosity do not reduce the filter function even at high temperature and high pressure. It is excellent.

기존의 필터에 대한 문제점은 필터 구조상 공기가 처음 유입되는 부분에 큰 입자상 물질을 여과시킬때 눈막힘 현상이 일어나면 필터의 기능이 현저하게 감소되는 단점이 있으며, 또 그만큼 내부에는 여과시키는 공기의 양이 적어 필터의 수명이 다하지 않은 상태에서 불가피한 교환을 하게 된다.The problem with the existing filter is that the filter function is significantly reduced when clogging occurs when the large particulate matter is filtered at the first air inflow part of the filter structure, and the amount of air filtered inside It is inevitable that the filter will be replaced when the filter life is not over.

이번에 발명한 다공성을 부여한 세라믹 멀티-튜브 필터는 한 개의 큰 필터가 아니라 작은 파이프형태의 관을 수직으로 장착한 것이어서, 비록 큰 입자상 물질을 여과시킨다 해도 파이프의 한 개가 필터로서의 기능이 저하 될 뿐 나머지 파이프형태의 필터는 제 기능을 다할 수 있는 장점이 있고, 수명도 기존의 필터보다는 적게는 3배 이상 많게는 5배까지도 길어진 것이 특징이다Porous ceramic multi-tube filter invented is not a big filter but a small pipe type vertically mounted, so even if large particulate matter is filtered, only one of the pipes deteriorates its function as a filter. The pipe-type filter has the advantage of being able to perform its function, and its life span is less than three times and up to five times longer than the existing filter.

또한, 다공성을 부여한 세라믹 멀티-튜브 필터는 사용조건에 따라서 필터의 크기를 조절할 수 있으며, 오염원의 종류에 따라서 필터의 기공을 조절할 수 있는 장점을 가지고 있다.In addition, the ceramic multi-tube filter having a porosity can control the size of the filter according to the conditions of use, and has the advantage of controlling the pore of the filter according to the type of contaminant.

다공성을 부여한 세라믹 멀티-튜브 필터는 멀티-튜브 필터구조의 벽면에 다공성을 부여하여 단위 시간당 여과비율을 높인 것이며, 세라믹필터의 장점을 살려서 고온에서도 여과의 기능을 다할 수 있으며, 세라믹필터의 장점인 화학적으로 안정하다는 장점이 있다.Porous ceramic multi-tube filter is to increase the filtration rate per unit time by giving porosity to the wall of the multi-tube filter structure. It has the advantage of being chemically stable.

일정한 체적에 대한 여과 면적을 최대화 할 수 있게 파이프형태의 관의 크기를 조절하여 생산할 수 있으며, 어느 한정된 제품의 크기가 아니라 원하는 크기의 필터의 크기와 직경, 그리고 필터의 기공도 0.005∼450㎛까지 조절 할 수 있는 것이다.It can be produced by adjusting the size of pipe in order to maximize the filtration area for a certain volume, not the size of any limited product, but the size and diameter of the filter of the desired size, and the pore size of the filter up to 0.005 ~ 450㎛ It can be adjusted.

기존의 필터는 고온·고압에서 사용 시 필터의 기능이 저하되고, 수명 또한 현저하게 감소하는 경향이 있다.Existing filters tend to degrade the filter's function when used at high temperatures and pressures and to significantly reduce their service life.

높은 온도에서 여과를 해야하는 설비에서는 기존의 집진장치의 거대화와 필터교환이 힘들고 필터의 수명 또한 감소하나, 이번에 발명된 멀티-튜브 필터는 고온(1300℃)에서도 견딜 수 있고 일정압력 이상에서도 필터의 파손이나 기타 균열이 일어나지 않는 장점이 있다.In facilities that require filtration at high temperatures, existing dust collectors are difficult to filter, filter replacement is difficult, and filter life is also reduced.However, the multi-tube filters invented can withstand high temperatures (1300 ℃) and break filters even beyond a certain pressure. Or other cracks do not occur.

또, 집진장치의 크기가 줄어들고 필터교환이 용이해져 고체 작업시에도 작업이 우수하며, 비용절감으로 경쟁력을 높일 수 있다.In addition, since the size of the dust collector is reduced and the filter is easily replaced, the work is excellent even in the solid work, and the cost can be reduced and the competitiveness can be increased.

배합한 원료는 롤 분쇄기에 분쇄가 골고루 이루어지도록 2∼3회 분쇄를 하고롤 혼합기에 혼합하여 분말상태의 원료와 첨가물이 고루 혼합이 되도록 3∼5회 정도를 롤 혼합기를 통해서 혼합한다. 압출성형시에 가장 적당한 원료를 만들어서 토련기로 토련을 4차까지 토련을 한 후 약 하루 정도 숙성을 시킨다.The blended raw materials are pulverized two or three times to evenly grind the roll mill and mixed in a roll mixer and mixed three to five times through a roll mixer so that the powdery raw materials and additives are evenly mixed. Make the most suitable raw material at the time of extrusion molding, and cultivate the pottery till the 4th and then mature for about a day.

<예 2>는 85%Al2O3소지에 carbon을 전체의 20∼25%로 혼합하고, CMC 2∼5%, PVA 1∼4%, PEG 3∼10%를 첨가하고 용매를 20∼23% 첨가하여 원료를 배합한다.In Example 2, carbon was mixed in 20% to 25% of the 85% Al 2 O 3 substrate, 2% to 5% CMC, 1% to 4% PVA, and 3% to 10% PEG were added and the solvent was added 20% to 23%. Blend the raw materials by adding%.

배합한 원료는 롤 혼합기에서 골고루 혼합이 이루어지도록 3∼5회 혼합을 하고, 하루를 밀봉상태에서 숙성을 시키고 토련기로 4차까지 토련을 한 다음에 다시 밀봉하여 하루를 숙성시킨다.The blended raw materials are mixed three to five times to evenly mix in a roll mixer, and aged one day in a sealed state, aged four times with a refining machine, and then sealed again to ripen one day.

<예 3>은 96%Al2O3소지에 carbon을 전체의 15∼20%로 혼합하고, CMC 3∼7%, PVA 2∼8%, PEG 5∼15%를 첨가하고 용매를 13∼18% 첨가하여 원료를 배합한다.In Example 3, carbon was mixed with 15% to 20% of the 96% Al 2 O 3 substrate, 3 % to 7% of CMC, 2% to 8% of PVA, and 5% to 15% of PEG were added, and the solvent was 13% to 18%. Blend the raw materials by adding%.

배합한 원료는 롤 홉합기를 통해서 혼합이 완전히 이루어지도록 5∼7회정도 혼합을 하고, 이틀정도 숙성을 시키고 숙성된 원료를 다시 토련기를 통해서 4차까지 토련을 한 후 다시 이틀정도 숙성을 시킨다.The blended raw materials are mixed 5-7 times to complete mixing through a roll mixer, and aged for 2 days, and the matured raw materials are retrained to the 4th through a refining machine and then aged for 2 days.

숙성시킨 원료는 도 1과 같이 원하는 튜브-필터의 크기에 맞는 노즐을 직경의 수축률을 계산해서 선택하고 압출성형기의 맨 앞부분에 장착을 하고, 혼합한 원료를 압출성형 한다. 압출 성형한 파이프는 약 70∼80℃, 길이 7m의 건조 컨베이어 밸트를 통과시킨 후 휘어지지 않도록 적재판에 적재를 한다.The aged raw material is selected by calculating the shrinkage of the diameter of the nozzle suitable for the size of the desired tube-filter as shown in Figure 1, is mounted on the front of the extruder, and the mixed raw material is extruded. The extruded pipe is loaded on a loading plate so as not to bend after passing through a drying conveyor belt of about 70 to 80 ° C. and a length of 7 m.

휘어지지 않도록 적재판에 적재를 한 성형된 파이프는 약 70∼150℃의 건조실에서 이틀정도 완전 건조를 시키고, 가스로에서 약 800∼900℃ 10시간정도로 가소를 하여 건식컷팅법으로 수축률을 계산해 원하는 길이로 컷팅을 한다.Molded pipes loaded on the loading plate to prevent bending are completely dried in a drying room at about 70 ~ 150 ℃ for about two days, and then calcined at about 800 ~ 900 ℃ for 10 hours in a gas furnace to calculate shrinkage rate by dry cutting method. Cut with.

컷팅을 한 성형된 멀티-튜브 필터는 가스로에서 1150∼1450℃로 약 7∼9시간동안 소성 한 후 3∼4시간정도 일정온도를 유지하고, 공기를 통과 시켜 일정 속도로 강제 냉각을 시킨 멀티-튜브 필터는 < 예 1 >의 경우가 가장 강도가 놓으며, < 예 2 > < 예 3 > 으로 갈수록 강도면에서 < 예 1 > 보다 낮은 것으로 나타난다.The molded multi-tube filter cut was calcined at 1150-1450 ° C. for about 7-9 hours, and then maintained at a constant temperature for about 3-4 hours, and forcedly cooled at a constant rate by passing air. In the case of <Example 1>, the tube filter has the strongest strength, and it appears that it is lower than <Example 1> in terms of strength toward <Example 2> and <Example 3>.

그리고 제품의 단가 면에서 경쟁력이 높으며, 성능면에서도 기존의 필터보다 좋은 성능을 나타내는 멀티-튜브 필터를 낮은 생산비용으로 생산하는데 어려움이 없는 < 예 1 >의 경우를 이용해서 멀티-튜브 필터를 생산하였다.In addition, the multi-tube filter is produced using the case of <Example 1>, which is competitive in terms of product cost and does not have difficulty in producing a multi-tube filter that shows better performance than conventional filters at a low production cost. It was.

이렇게 해서 높은 기공률과 기공의크기, 높은 압축강도를 보이는 <예 1>을 이용해 도 2와 같이 성형된 파이프는 12×12형태, 16×16형태 등 집진장치의 조건을 고려하여 최적의 조건을 파악한 후 결정을 하여 파이프의 개수를 정한 다음, 지지대의 조건에 맞는 크기로 일정한 공간을 유지하게 하여 도3의 지지판을 이용해서 도 5의 부분에 결합이 되는 윗 부분은 도 3의 지지판에 먼저 연결의 해 놓고 케스타블을 이용해 파이프의 내부에는 케스타블이 들어가지 않도록 주의하여 파이프와 파이프 사이를 고정시킨다.Thus, the pipe formed as shown in FIG. 2 using <Example 1> showing high porosity, pore size, and high compressive strength was found in consideration of the conditions of the dust collector such as 12 × 12 and 16 × 16 shapes. After determining the number of pipes to determine the size, and then maintain a constant space in a size that meets the conditions of the support, the upper portion that is coupled to the portion of Figure 5 using the support plate of Figure 3 is first connected to the support plate of Figure 3 Using castables, fix the pipes between the pipes being careful not to put the castables inside the pipes.

도 6에 결합되는 부분은 도 3의 지지판에 먼저 캐스타블을 일정량을 부어 놓고 파이프를 밀어 넣는다. 이때 케스타블이 파이프 내부까지 차서 들어갈 수 있도록 케스타블을 양을 조절하여 파이프를 완전 밀봉시킨다.The portion coupled to FIG. 6 first pours a certain amount of the castable onto the support plate of FIG. 3 and pushes the pipe. At this time, the amount of castable is adjusted to completely fill the pipe so that the castable can be filled inside the pipe.

도 3의 지지대를 분리시켜 윗 부분의 파이프는 개방상태로 되어있고, 아랫부분은 파이프가 밀봉상태로 되어있는 파이프의 형태를 도 5의 집진장치에 고정되는부분에는 케스타블로 조립된 파이프 윗 부분에 결합을 시키고, 도 6의 하부 지지대는 케스타블로 조립된 파이프 아랫 부분에 결합을 시켜, 도 5의 집진장치에 고정되는 부분과 도 6의 하부 지지대를 서로 연결할 수 있는 핀을 이용해서 고정을 시킨다.Removing the support of Figure 3, the upper part of the pipe is in an open state, the lower part of the pipe in the form of the pipe is sealed in the dust collector of Figure 5 is fixed to the upper part of the pipe assembled with a castable The lower support of Figure 6 is coupled to the lower portion of the pipe assembled to the castable, it is fixed by using a pin that can connect the portion fixed to the dust collector of Figure 5 and the lower support of Figure 6 with each other.

본 발명은 기공률과 기공의 크기조절, 그리고 압축강도의 제어로 인해 기존의 필터의 문제점을 보완하고, 기능을 향상시킨 것으로서 튜브형태의 관을 여러 개 장착하여 필터의 수명이 길어지고 여과하는 장소에 따라서 기공의 크기를 조절 가능하며 단위 면적당 여과 비율을 최대로 할 수 있게 튜브형태의 관의 크기를 조절할 수 있다.The present invention is to compensate for the problems of the existing filter due to the porosity, pore size control, and the control of the compressive strength, and to improve the function, it is equipped with a plurality of tube-type pipe in the place where the life of the filter is longer Therefore, the size of the pore can be adjusted and the size of the tube in the form of a tube can be adjusted to maximize the filtration ratio per unit area.

고온과 고압에서 필터의 기능이 저하되는 것을 고려하여 고온과 고압에서도 기능이 저하되지 않고, 필터의 특성상 별도의 냉각장치를 필요로 하지 않는다는 것이다.Considering the deterioration of the function of the filter at high temperature and high pressure, the function does not deteriorate even at high temperature and high pressure, and the filter does not require a separate cooling device.
