Description
본 발명은 역기류 탈진식 여과집진 방법에 관한 것으로, 보다 상세하게는 여과포로서 부직포를 사용하고 외면여과를 행하는 역기류 탈진식 여과집진 방법에 관한 것이다.TECHNICAL FIELD The present invention relates to a reverse airflow dedusting filter collection method, and more particularly, to a reverse airflow dedusting filter collection method using a nonwoven fabric as a filter cloth and performing external filtration.
여과집진기술은 배가스중에 함유된 분진을 여과포를 이용하여 포집하는 방법으로 전기집진기술, 세정집진기술 등과 더불어 산업계에서 널리 이용되고 있다. 여과집진기술은 산업체의 분진발생공정에는 대부분 이용될 수 있으며, 대표적인 산업분야로는 철강공업분야, 소각분야, 시멘트공업분야, 각종 연소공정, 제지공업분야, 코크스 분야 등을 들 수 있다.The filter dust collecting technology is a method of collecting dust contained in the flue gas by using a filter cloth, and is widely used in the industry along with the electrostatic dust collecting technology and the cleaning dust collecting technology. Filtration dust collection technology can be used mostly in the dust generation process of the industry, the representative industrial sectors include steel industry, incineration, cement industry, various combustion process, paper industry, coke.
이같은 여과집진기는 여과포 표면에 포집된 분진을 탈진하는 방법에 따라 달라질 수 있으며, 탈진방법에 따라 진동탈진방식(Shake Cleaning), 역기류탈진(Reverse Air Cleaning), 충격기류탈진(Pulse-Jet Cleaning)등이 있다. 이중에서 역기류 탈진식과 충격기류 탈진식이 산업체에 널리 이용되고 있으며, 이들 방법은 각각의 특징에 알맞게 적용시키고 있다.Such bag filter may vary depending on the method of dedusting the dust collected on the surface of the filter cloth, and depending on the method of dedusting, it may be shake cleaning, reverse air cleaning, or pulse-jet cleaning. Etc. Among them, counter-air exhaust and impact air degassing are widely used in industry, and these methods are suited to their respective characteristics.
여과집진기 시스템에서 역기류 탈진방법은 단위 집진실에서 함진가스의 유입을 중단시킨 후 함진가스의 유입방향과 반대방향으로 공기중의 공기를 흡입하여 여과포 표면에 부착된 분진을 탈진시키는 방법이다. 역기류 탈진방식에 대한 개략도를 도 1에 나타내었다. 이 방법의 특징은 도 1에서도 나타난 바와같이 여과포의 내면에 분진이 포집되며(내면여과), 여과백은 직포(Woven filter)를 사용한다는 것이다. 집진실내의 여과포는 상부와 하부를 동시에 고정시키며, 상부는 고리로 연결하여 텐션을 조정하여 집진실에 부착시킨다. 여과포는 하부가 열려있고 상부가 막혀있다.In the dust collector system, the reverse airflow dedusting method is a method for dedusting the dust attached to the surface of the filter cloth by stopping the inflow of the impregnated gas in the unit dust chamber and sucking the air in the air in a direction opposite to the inflow direction of the impregnated gas. A schematic diagram of the counter-air exhaustion method is shown in FIG. 1. The characteristic of this method is that dust is collected on the inner surface of the filter cloth as shown in FIG. 1 (internal filtration), and the filter bag uses a woven filter. The filter cloth in the dust collecting chamber fixes the upper part and the lower part at the same time, and the upper part is connected to the dust collecting chamber by adjusting the tension by connecting with a ring. The filter cloth is open at the bottom and clogged at the top.
하지만, 이러한 방식은 특성상 전체 집진장치는 몇 개의 단위집진실로 구성되어 있으며, 여과속도가 대체적으로 느려 여과포 단위면적당 처리가스 유량이 적으므로(여과속도가 작음) 집진장치의 설치면적이 많이 필요하다는 것이다. 이와같이, 종래의 역기류 탈진식 여과집진기는 내면여과를 이용하기 때문에 여과속도를 크게 할 수 없어 동일한 배가스량에 대하여 집진기 본체가 커지는 문제점이 있다. 한편, 내면여과식 역기류탈진 여과집진기는 사용 여과포로서 직포(Woven)를 사용하고 있다.However, this method is characterized by the fact that the whole dust collector is composed of several unit dust collection chambers, and because the filtration speed is generally slow, the processing gas flow rate per unit area of the filter cloth is small (small filtration rate), and thus the installation area of the dust collector is large. . As described above, since the conventional counter-airflow dust filter type dust collector uses inner filtration, the filtration rate cannot be increased, and thus, the dust collector main body becomes large for the same amount of exhaust gas. On the other hand, the inner filtration backflow dedusting bag filter uses a woven fabric as a used filter cloth.
이에, 본 발명자들은 상기 문제점을 해결하기 위해 연구와 실험을 거듭하고 그 결과에 근거하여 본 발명을 제안하게 된 것으로, 본 발명은 역류기탈진식 여과집진기의 집진방식을 외면여과 방식을 적용함으로서, 기존에 비해 처리속도가 빠를 뿐만아니라 탈진력이 우수한 역류기 탈진식 여과집진 방법을 제공하고자 하는데, 그 목적이 있다.Accordingly, the present inventors have repeatedly conducted research and experiments to solve the above problems and propose the present invention based on the results, and the present invention applies an external filtration method to the dust collecting method of the backflow dedusting filter bag. The present invention is to provide a counterflow type dust collecting filter collection method having a faster processing speed as well as an excellent dust collecting power, and has an object thereof.

상기 목적을 달성하기 위한 본 발명은 함진가스를 여과포를 통과시켜 집진하고 청정가스를 외부로 배출하는 역류기 탈진식 여과집진 방법에 있어서, 상기 여과포의 재질을 부직포로 하고, 상기 함진가스가 여과백의 바깥쪽으로 부터 여과되어, 청정가스가 내부로 함입된 후 배출되는 외면여과를 행하는 것을 특징으로 하는 외면여과를 이용하는 역기류 탈진식 여과집진 방법에 관한 것이다.In order to achieve the above object, the present invention provides a counter-flow dust collector type dust collecting method for collecting dust-containing gas through a filter cloth and discharging clean gas to the outside, wherein the material of the filter cloth is made of a nonwoven fabric, The present invention relates to a reverse airflow dedusting type filter precipitating method using external filtration, which is filtered from the outside and subjected to external filtration discharged after the clean gas is introduced into the interior.
이하, 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.
본 발명에서는 여과속도가 크고 운영비용도 줄일 수 있는 수단으로, 탈진방식은 기존의 역기류 탈진방법을 이용하고, 집진기 본체의 집진방식은 외면여과방식을 이용하고 있다.In the present invention, as a means for increasing the filtration speed and reducing the operating cost, the dust extraction method uses a conventional backflow dust removal method, and the dust collection method of the dust collector main body uses an external filtration method.
본 발명에서는 여과집진기의 집진실 내의 여과백의 지지 및 설치는 내부에 철물지지대(bag cage)나 리테이너(retainer) 등을 적용하여 여과포를 지지할 수 있다. 도 2는 본 발명에서 개발한 집진방법을 적용할 수 있는 장치에 대한 바람직한 일예를 보이는 것으로, 여과포의 하부가 막혀 있고 여과포의 상부는 열려있으며 철물지지대를 통하여 집진실 상부에 연결되어 있다. 이와같이, 본 발명에서는 상기 여과백의 내부가 함진가스에 직접 닿지 않도록 막혀있고, 청정가스를 배출하는 부분이 뚫려있도록 구성하여, 외면여과를 행하는 것이다.In the present invention, the support and installation of the filter bag in the dust collecting chamber of the filter dust collector may support a filter cloth by applying a bag cage, a retainer, or the like therein. Figure 2 shows a preferred example of the device to which the dust collection method developed in the present invention can be applied, the lower part of the filter cloth is blocked, the upper part of the filter cloth is open and connected to the upper dust collecting chamber through the hardware support. As described above, in the present invention, the inside of the filter bag is blocked so as not to come in direct contact with the impregnated gas, and the part for discharging the clean gas is formed so as to perform external filtration.
또한, 본 발명에서의 상기 여과백은 부직포를 이용하여 제작한 것을 적용하고 있다. 상기 부직포는 기존에 적용되고 있는 직포와 물성이 많이 차이나지 않는 것이면 어느 것으로나 대체가능하다. 예를들면, 기존에 여과포로 사용되고 있던 직포로서, 폴리에스터 재질이고, 공기투과도 15cc/cm2/sec, 공극율 65%, 인장강도(길이) 165kg/cm2, 인장강도(폭) 180kg/cm2, 파열강도 47kg/cm2인 것을 들 수 있는데, 이를 대체할 수 있는 부직포로서 일예를 들면, 폴리에스터 재질이고, 공기투과도 16cc/cm2/sec, 공극율 62%, 인장강도(길이) 160kg/cm2, 인장강도(폭) 180kg/cm2, 파열강도 457kg/cm2인 것을 들 수 있다.In addition, the said filter bag in this invention applies what was produced using the nonwoven fabric. The nonwoven fabric may be replaced with any one as long as the properties of the nonwoven fabric do not differ significantly from those of the conventional woven fabric. For example, a woven fabric previously used as a filter cloth, which is made of polyester, has an air permeability of 15 cc / cm 2 / sec, a porosity of 65%, a tensile strength of 165 kg / cm 2 , and a tensile strength of 180 kg / cm 2. , Rupture strength 47kg / cm 2 , non-woven fabric that can replace this, for example, polyester material, air permeability 16cc / cm 2 / sec, porosity 62%, tensile strength (length) 160kg / cm 2 , tensile strength (width) 180kg / cm 2 , rupture strength 457kg / cm 2 It can be mentioned.
이와같은 본 발명의 조건을 만족하는 방법으로 여과하는 경우 그 여과속도는 기존에 비해 큰 1.9m/min정도 까지의 속도로도 조업할 수 있는 것이다.In the case of filtration in a manner that satisfies the conditions of the present invention, the filtration rate can be operated even at a speed of about 1.9 m / min.
이하, 실시예를 통하여 본 발명을 보다 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to Examples.

(결과 분석)(Analyze results)
일반적으로, 여과집진기의 성능에서 가장 중요한 것은 탈진성능이며 탈진성능을 판단할 수 있는 기준은 압력손실이다. 통상적인 여과집진기의 원전중 압력손실의 관리기준은 150mmAq이하이며 압력손실이 200-300mmAq이상이 되면 원하는 풍량이 나오지 못하므로 여과백을 교체하게 된다.In general, the most important factor in the performance of the bag filter is the dust removal performance, and the criterion for determining the dust removal performance is the pressure loss. The standard for controlling the pressure loss in nuclear power plants of the conventional filter dust collector is 150mmAq or less, and when the pressure loss is 200-300mmAq or more, the desired air volume does not come out and the filter bag is replaced.
따라서, 본 실시예에서는 상기한 바와같은 조건으로 집진실험을 행하여 운전시간에 따른 압력손실을 측정하고, 그 결과를 발명예의 경우는 도 4에, 종래예의 경우는 도 5에 각각 나타내었다.Therefore, in the present embodiment, dust collection experiments were performed under the conditions described above to measure the pressure loss according to the operation time, and the results are shown in FIG. 4 in the case of the invention example and in FIG. 5 in the case of the conventional example.
도 4에 나타난 집진실험 결과는 본 발명의 조건을 만족하는 집진방법을 적용하여 연속적으로 집진 및 탈진을 5번 수행한 실험결과이다. 집진시에는 주어진 조건에서 120mmAq의 압력손실까지 분진을 투입한 후 주어진 역세조건으로 탈진을 수행할 경우 압력손실이 약20-30mmAq로 감소하는 것으로 나타났다. 이와같은 결과는 5회 연속 실험을 수행한 경우 매우 유사하게 나타났으며, 계속적으로 집진 및 탈진실험을 수행하여도 매우 유사한 경향이 나타날 것으로 판단된다. 이같은 실험조건에서는 집진시에 여과집진기의 여과속도를 1.5m/min으로 행하였는데, 이는 통상적인 내면여과를 이용한 역기류 탈진식 여과집진기의 여과속도인 0.9-1.2m/min보다도 빠른 것으로, 본 발명에 의하면 기존방식 보다 여과속도를 크게 할 수 있다는 것을 보여주고 있다. 즉, 부직포를 사용하며 외면여과를 이용한 역세탈진기술은 직포를 사용하며 내면여과를 이용한 역세탈진기술 보다 주어진 여과면적으로 보다 많은 배가스를 처리할 수 있다는 것이다.The dust collection test results shown in FIG. 4 are experimental results of continuously collecting and dusting five times by applying a dust collecting method satisfying the conditions of the present invention. At the time of dust collection, when the dust was injected up to a pressure loss of 120 mmAq at a given condition, and the dust was removed under the given backwash condition, the pressure loss was reduced to about 20-30 mmAq. These results were very similar when the five consecutive experiments were performed, and even when the dust collection and exhaustion experiments were continuously performed, it would be very similar. Under these experimental conditions, the filtration rate of the bag filter at the time of dust collection was performed at 1.5 m / min, which is faster than the 0.9-1.2 m / min, which is the filtration speed of the conventional backflow dust filter. Shows that the filtration rate can be made larger than the conventional method. In other words, non-woven fabrics using reverse filtration using external filtration can process more exhaust gas with a given filtration area than woven fabrics and reverse filtration using internal filtration.
이에 반하여, 도 5에 나타난 집진실험 결과는 종래의 집진방법을 적용하여 연속적으로 집진 및 탈진을 5번 수행한 실험결과이다. 집진시에는 주어진 조건에서 120mmAq의 압력손실까지 분진을 투입한 후 주어진 역세조건으로 탈진을 수행할 경우 압력손실이 약30-40mmAq로 나타났다.On the contrary, the result of the dust collection experiment shown in FIG. 5 is an experiment result of continuously collecting and dedusting five times by applying the conventional dust collection method. At the time of dust collection, when the dust was injected up to a pressure loss of 120 mmAq under the given conditions, the pressure loss was about 30-40 mmAq when the dust was exhausted under the given backwash conditions.
상술한 바와같은 본 발명에 의하면, 부직포를 이용하여 여과백을 구성하고 집진방식을 외면여과 방식으로 하는 역류기 탈진식 여과집진방법에 의해 집진을 행함으로서, 기존의 여과처리속도에 비해 빠를 뿐만아니라 탈진력이 우수한 효과를 얻을 수 있다.According to the present invention as described above, by constructing the filter bag using a non-woven fabric and collecting by the counter-flow dust collector type dust-collecting method, the dust-collecting method is the surface filtration method, it is not only faster than the existing filtration treatment speed. Excellent effect of dust removal power can be obtained.
