그러나, 일차적으로 탈진시킨 후 분진이 상기 여과포(5)의 일부에 남게되거나 분산적으로 잔재할 시에는 압력손실이 높아 일정한 분사압으로는 그 이상 분진의 제거가 이루어지지 못하는 한계가 있었으며, 과도한 분사압을 가하면 상기 여과포(5)의 수명을 단축시키게 될 뿐만 아니라 에너지 소모에 의해 운전비가 상승된다는 문제점이 있었다.However, when dust is left in a part of the filter cloth 5 after being primarily dedusted or dispersedly remaining, the pressure loss is high, and there is a limit that no further dust can be removed at a constant injection pressure. Applying pressure not only shortens the life of the filter cloth 5, but also increases the operating cost due to energy consumption.

상기와 같은 문제점을 해결하기 위해 안출된 본 발명은, 여과포의 압력손실을 줄여 운전비를 절감시키며, 여과포의 수명을 연장하여 교체비용도 절감시킬 수 있는 구조의 여과집진기의 이중탈진장치를 제공하는 데 목적이 있다.The present invention devised to solve the above problems, to reduce the operating pressure by reducing the pressure loss of the filter cloth, to provide a double dust extraction device of the bag filter structure of the structure that can reduce the replacement cost by extending the life of the filter cloth There is a purpose.

상기와 같은 구성을 가지는 본 발명을 다음의 도면을 참조하여 상세히 설명하고자 한다. 도 2는 본 발명에 따른 여과집진기의 이중탈진장치의 일실시예를 도시한 종단면도이고, 도 3은 도 2의 일실시예가 설치된 여과집진기를 도시한 종단면도이며, 도 4는 도 3의 횡단면도이다.The present invention having the configuration as described above will be described in detail with reference to the following drawings. Figure 2 is a longitudinal sectional view showing an embodiment of a double dust extraction device of the filter precipitator according to the present invention, Figure 3 is a longitudinal sectional view showing a filter precipitator equipped with an embodiment of Figure 2, Figure 4 is a cross-sectional view of FIG. to be.

본 발명에 따른 여과집진기의 이중탈진장치(100)는, 분진이 함유된 외기를 유입하여 여과포(210)를 거쳐 여과시킨 후 외부배출시키는 여과집진기(200)에 설치되는 탈진장치(100)에 있어서, 블로우노즐(120)과 탈진막대(130)를 함께 구비하여 압축공기의 충격역기류와 탈진막대(130)와의 충격력에 의해 상기 여과포(210)를 이중으로 탈진시키는 작동구조를 가진다.In the dust collecting device 100 of the dust collector 100 according to the present invention, the dust collecting device 100 is installed in the filter dust collector 200 which discharges the outside air containing the dust and filters it through the filter cloth 210 and then discharges it. In addition, the blow nozzle 120 and the dust collecting rod 130 are provided together to have an operation structure for dedusting the filter cloth 210 by the impact force between the impact backflow air of the compressed air and the dust collecting rod 130.

상기 블로우노즐(120)은 상기 여과집진기(200) 내부의 외기 흐름에 충격역기류를 형성시키는 방향으로 상기 여과포(210)에 압축공기를 분사시켜 상기 여과포(210)를 탈진시키는 공지된 기술내용을 따른다.The blow nozzle 120 is sprayed with compressed air to the filter cloth 210 in the direction of forming a shock backflow to the outside air flow inside the bag filter 200 is a known technology for dedusting the filter cloth 210 Follow.

상기 블로우노즐(120)은 외부 급기원에서 생산, 공급된 압축공기를 일시 저장한 에어헤더에서 분기되어 상기 여과포(210)의 배열선에 따라 배치된 블로우관(110)상에, 각각의 여과포(210) 개방단부측에 대응되는 위치에 상기 여과포(210)측으로 돌출되게 형성된다.The blow nozzle 120 is branched from the air header temporarily stored in the compressed air produced and supplied from an external air supply source, on the blow pipe 110 disposed along the alignment line of the filter cloth 210, each filter cloth ( 210 is formed to protrude toward the filter cloth 210 at a position corresponding to the open end side.

도 2에 도시된 본 발명의 일실시예에서 상기 블로우노즐(120)은 상기 블로우관(110)상에 그 돌출길이를 조정시킬 수 있도록 나사결합됨으로써, 압축공기의 분사가 상기 여과포(210) 전반에 고르게 이루어지지 않을 시 상기 여과집진기(200)나 탈진장치(100)를 별도로 개조변경시키지 않고도 상기 여과포(210)에의 분사거리를 조정시키는 것만으로 상기 여과포(50)의 길이방향으로 균일하게 탈진시킬 수 있다.In the embodiment of the present invention shown in Figure 2 the blow nozzle 120 is screwed to adjust the protruding length on the blow pipe 110, so that the injection of compressed air through the filter cloth 210 If it is not even in the dust collector 200 or the dust collector 100 to be uniformly dedusted in the longitudinal direction of the filter cloth 50 only by adjusting the injection distance to the filter cloth 210 without modifying and changing separately. Can be.

상기 블로우노즐(120)로부터 분사된 압축공기는 분사압 및 대기압과의 압력차에 의해 상기 여과포(210)의 눈사이를 통과하면서 상기 여과포(210) 외부면에 부착된 분진을 탈진시키게 되며, 상기 여과포(210)는 압축공기의 작용에 의해 순간적으로 팽창된 상태에서 탈진이 이루어지게 된다.Compressed air injected from the blow nozzle 120 is to exhaust dust attached to the outer surface of the filter cloth 210 while passing between the eyes of the filter cloth 210 by the pressure difference between the injection pressure and the atmospheric pressure, The filter cloth 210 is exhausted in a state in which it is momentarily expanded by the action of compressed air.

상기 탈진막대(130)는 상기 블로우노즐(120)에 의해 팽창된 여과포(210)가 부딪히도록 상기 여과포(210) 외측에 다수가 배치되어, 상기 블로우노즐(120)에서 분사된 압축공기에 의해 순간적으로 팽창된 상기 여과포(210)에 충격력을 부여함으로써 상기 여과포(210)를 털어 탈진시킨다.The exhaustion rod 130 is disposed a plurality outside the filter cloth 210 so that the filter cloth 210 is expanded by the blow nozzle 120, by the compressed air injected from the blow nozzle 120 The filter cloth 210 is shaken off by imparting an impact force to the filter cloth 210 that is expanded in an instant.

상기 탈진막대(130)는 특정한 막대형상에 한정되지 않고 상기 여과포(210) 외측에서 팽창된 상기 여과포(210)에 충격력을 가할 수 있는 다양한 형태의 실시예 전부를 포함하며, 압축공기의 분사에 의해 팽창, 탈진중인 상기 여과포(210)에 물 리적인 충격을 부여함으로써 동일한 분사압으로도 상기 여과포(210)를 보다 효율적으로 탈진시키게 된다.The dust removal rod 130 is not limited to a specific rod shape and includes all the various types of embodiments capable of applying an impact force to the filter cloth 210 inflated outside the filter cloth 210, by the injection of compressed air. By imparting a physical impact on the filter cloth 210 that is inflated and exhausted, the filter cloth 210 can be more efficiently degassed even at the same injection pressure.

동일한 분사압으로도 상기 여과포(210)를 보다 우수한 성능으로 탈진시킴으로써, 운전 시 상기 여과포(210)를 통과하는 공기의 압력손실이 낮아지므로 송풍기의 동력소모가 줄어 운전비를 줄일 수 있으며, 여과포의 수명 또한 연장시킬 수 있다.By dedusting the filter cloth 210 with better performance even at the same injection pressure, the pressure loss of the air passing through the filter cloth 210 during operation is lowered, thereby reducing the power consumption of the blower and reducing the operating cost, and the life of the filter cloth. It can also be extended.

상기의 효과 뿐만 아니라, 상기 여과포(210)가 압출공기에 의해 팽창확장될 시 상기 탈진막대(130)가 외측에서 상기 여과포(210)의 팽창을 일부저해하게 됨에 따라 상기 여과포(210) 내부공간부 전반의 확장 및 탈기에 의한 분사공기의 압력손실을 줄여 분사공기의 이용에 소요되는 운전비를 추가로 절감할 수 있다.In addition to the above effects, when the filter cloth 210 is expanded and expanded by the extruded air, the dust-absorbing rod 130 partially inhibits the expansion of the filter cloth 210 from the outside, so that the filter cloth 210 has an internal space. By reducing the pressure loss of the injection air due to the expansion and degassing of the first half, it is possible to further reduce the operating cost of using the injection air.

그리고, 상기 여과포(210)에 손상을 가할 정도의 무리한 분사압을 가할 필요가 없어져 상기 여과포(210)의 수명을 연장시킬 수 있고, 상기 여과포(210)의 초기성능 또한 보다 장시간 유지시킬 수 있어 상기 여과포(210)의 교체비용을 보다 절감시킬 수 있다.In addition, it is not necessary to apply an excessive injection pressure to damage the filter cloth 210 can extend the life of the filter cloth 210, the initial performance of the filter cloth 210 can also be maintained for a longer time It is possible to further reduce the replacement cost of the filter cloth (210).

상기 탈진막대(130)는 상기 여과포(210)를 고정시키는 튜브시트(220)상에 결합됨에 있어서, 일체로 고정결합되면 상기 여과포(210)의 팽창압력에 의한 전단력 및 굽힙가압력이 상기 튜브시트(220)과의 연결부에 집중되어 수명이 단축되기 쉽다.In the dust collecting rod 130 is coupled on the tube sheet 220 for fixing the filter cloth 210, when fixed integrally coupled to the tube sheet is shear and bending pressure due to the expansion pressure of the filter cloth 210 Concentrated on the connection portion with 220, the life is likely to be shortened.

상기 탈진막대(130)를 상기 튜브시트(220)상에 힌지결합이나 고리결합에 의해 매달려 흔들릴 수 있도록 고리결속시키면, 상기 여과포(210)가 팽창되어 상기 탈진막대(130)에 부딪힐 시 상기 탈진막대(130)가 상기 여과포(210)를 가압시키면서도 소폭으로 밀려 고리결속부(131)를 중심으로 회동하게 되어 상기 탈진막대(130) 일부에 무리한 가압력이 집중되는 것을 방지시킬 수 있다.If the dust-binding rod 130 is bound by the hinge or ring coupling on the tube sheet 220 so as to be swayed and shaken, the filter cloth 210 is expanded to hit the dust-off rod 130 when the dust is removed. The rod 130 is pushed slightly even while pressing the filter cloth 210 to rotate around the ring binding portion 131 to prevent concentration of excessive pressing force on a part of the exhaust bar 130.

상기 탈진막대(130)를 고리결속부(131)에 의해 회동가능하게 결합시킨 경우, 압축공기의 분사압력이나 상기 여과포(210)의 재질, 분진의 부착성질에 따라 상기 여과포(210)에 충격력을 적합하게 부여할 수 있을 정도의 하중으로 상기 탈진막대(130)의 자중을 조정시킬 수 있도록 하부에 교체가능한 추(132)를 구비함이 바람직하다.When the dust collecting rod 130 is rotatably coupled by the ring binding unit 131, impact force is applied to the filter cloth 210 according to the injection pressure of compressed air, the material of the filter cloth 210, and the adhesion property of the dust. It is preferable to have a replaceable weight 132 at the bottom to adjust the weight of the dust removal rod 130 to a load that can be appropriately applied.

그리고, 상기 여과포(210) 외측에 상기 탈진막대(130)가 여러개 설치됨에 따라, 입자가 큰 분진이 상기 여과포(210)의 외면에 도달되기 전에 상기 여과포(210)를 향하는 관성력에 의해 상기 탈진막대(130)와의 충돌에 의해 제진되어 전처리됨으로써 상기 여과포(210)에의 분진부착량을 상당량 줄일 수 있다.In addition, as a plurality of the dust collecting rods 130 are installed outside the filter cloth 210, the dust collecting rods are formed by the inertia force toward the filter cloth 210 before the large particles reach the outer surface of the filter cloth 210. The dust removal amount by the collision with the 130 and pretreatment can significantly reduce the amount of dust adhering to the filter cloth 210.

상기 탈진막대(130)를 상기 여과포(210)에 인접한 단부는 완곡한 곡면을 이루도록 형성시키고 타측단부는 평탄면을 이루도록 형성시키면, 상기 여과포(210)와의 접촉이 무리없이 이루어질 수 있으면서도 상기 여과포(210)측으로 이동중인 분진의 제거효과를 극대화시킬 수 있다.When the end of the exhaust bar 130 is formed to form a curved curved surface and the end adjacent to the filter cloth 210 and the other end is formed to form a flat surface, while the contact with the filter cloth 210 can be made without difficulty, the filter cloth 210 It is possible to maximize the removal effect of dust moving to the side.

상기 탈진막대(130)를 상기 튜브시트(220)상에 결합시킴에 있어서는, 정위치에 고정되게 구속시키지 않고 상기 튜브시트(220)상에 슬라이딩이동가능하게 결합시키면, 분진의 화학적, 물리적 성질에 따라 상기 여과포(210)와의 이격거리를 조정시킴으로써 적합하게 운용시킬 수 있다.In the coupling of the dust collecting rod 130 on the tube sheet 220, by slidingly coupled on the tube sheet 220 without being fixedly fixed in place, the chemical and physical properties of the dust Therefore, it can be suitably operated by adjusting the separation distance with the filter cloth 210.

상술한 바와 같은 구성에 의한 본 발명은, 압축공기의 충격역기류에 의해 여과포를 탈진시킴과 동시에 팽창된 여과포를 탈진막대가 털어주게 되어 일정한 분사압의 압축공기를 이용해서 보다 효율적으로 분진을 제거시킬 수 있다.According to the present invention having the above-described configuration, the filter cloth is dedusted by the impact backflow of the compressed air and the dedusting rod shakes off the expanded filter cloth, so that dust is more efficiently removed by using compressed air having a constant injection pressure. You can.

이에 따라, 여과포의 압력손실이 낮아지므로 송풍기의 동력소모가 줄어 운전비를 줄일 수 있으며, 여과포의 수명 또한 연장시킬 수 있다는 효과가 있다.Accordingly, since the pressure loss of the filter cloth is lowered, the power consumption of the blower is reduced to reduce the operating cost, and the life of the filter cloth can also be extended.

또한, 탈진막대가 여과포 외측에서 여과포의 팽창확장을 일부저해하여 분사공기의 압력손실을 줄임으로써 고압의 압축공기 공급에 소요되는 운전비를 더 절감시킬 수 있다는 다른 효과가 있다.In addition, there is another effect that the dust removal rod further reduces the operating cost required for supplying the compressed air at high pressure by reducing the pressure loss of the injection air by partially inhibiting the expansion of the filter cloth outside the filter cloth.

그리고, 여과포에 무리한 분사압을 가할 필요가 없어 여과포의 수명을 더 연장시킬 수 있고, 교체비용 또한 더 절감시킬 수 있다는 다른 효과가 있다.In addition, there is another effect that it is not necessary to apply an excessive injection pressure to the filter cloth to further extend the life of the filter cloth, and further reduce the replacement cost.

또한, 탈진막대와 분사노즐의 여과포와의 이격간격을 조정시킬 수 있어 분진의 탈진상태와 분진의 화학적, 물리적 성질에 따라 적합하게 운용시킬 수 있다는 다른 효과가 있다.In addition, the separation interval between the dust removal rod and the filter cloth of the injection nozzle can be adjusted, there is another effect that can be suitably operated according to the dust exhausted state and the chemical and physical properties of the dust.

그리고, 입자가 큰 분진이 여과포의 외면에 도달되기 전에 탈진막대와의 충돌에 의해 제진됨에 따라 여과포에의 분진부착량을 줄일 수 있다는 다른 효과가 있다.Then, as the particles having large particles are dusted off by the collision with the dust removal rod before reaching the outer surface of the filter cloth, there is another effect that the amount of dust adhered to the filter cloth can be reduced.
