본 발명은 집진기에 대한 것으로서, 좀 더 상세히는 간단한 구조변경을 통해 집진기의 탈진효율을 크게 증대시킬 수 있는 새로운 구조의 집진기에 대한 것이다.The present invention relates to a dust collector, and more particularly, to a dust collector of a new structure that can greatly increase the dust removal efficiency of the dust collector through a simple structure change.

집진기는 분진이나 기타 유해성분 등이 함유된 가스를 배출하는 플랜트나 작업장 등에서 분진이나 유해성분의 이물질 등을 걸러내기 위한 장치로서, 도 1과 같이, 케이스(1)의 내부에 다수의 필터백(4)이 리테이너(2)를 둘러싸도록 구비되고, 분진이나 유해성분 등의 이물질이 함유된 에어가 케이스(1)의 유입구(7)로 유입되어 필터백(4)을 거쳐서 분진 등이 걸러진 후에 흡입팬(9)이 구비된 배출구(8)를 통해 외부로 배출된다. 그리고, 필터백(4)의 상부에는 에어공급관(10)이 지나는데, 이 에어공급관(10)에는 필터백(4)의 상부마다 분사공(12)이 각각 형성된다. 따라서, 장시간의 집진 동작을 통해 필터백(4)에 분진이 축적되어 필터백(4)의 통공이 막혀서 여과효율이 저하되면, 주기적으로 에어분사공(12)에서 고압의 에어를 분사하여 필터백(4)을 요동시키서 필터백(4)의 외측면에 부착된 분진을 탈진처리하게 된다.The dust collector is a device for filtering foreign matter of dust or harmful components in a plant or a workplace that discharges gas containing dust or other harmful components, and the like, as shown in FIG. 1. 4) is provided so as to surround the retainer 2, and the air containing foreign substances such as dust or harmful components flows into the inlet 7 of the case 1, and the dust is filtered through the filter bag 4, and then suctioned. It is discharged to the outside through the discharge port 8 provided with a fan (9). Then, the air supply pipe 10 passes through the upper portion of the filter bag 4, the injection hole 12 is formed in each of the upper portion of the filter bag (4). Therefore, when dust accumulates in the filter bag 4 through long time dust collection operation, and the filtration efficiency is reduced by blocking the through-holes of the filter bag 4, the high pressure air is periodically injected from the air injection hole 12 to filter the bag. By shaking (4), the dust attached to the outer surface of the filter bag (4) is dust-treated.

그런데, 종래의 이러한 집진기는 에어공급관(10)에 형성된 에어분사공(12)이 대체로 원형의 통공으로 이루어져서 필터백(4)의 상부에서 수직으로 하향개방되도록 형성되어 있으므로, 에어분사공(12)을 통해 분사된 에어의 분사각도가 대체로 수직방향 또는 수직에 가까운 방향에 국한되므로, 수직방향으로 연장된 필터백(4)의 측면에 대해 빗방향으로 스치면서 분사되므로, 필터백(4)에 대한 충격 효과가 상대적으로 작고, 또한 필터백(4)의 상부에는 분사에어가 도달되지 않아서 필터백(4)의 상부에 부착된 분진들은 더욱 잘 떨어지지 않는 문제점이 있었다.By the way, such a dust collector in the prior art is formed so that the air injection hole 12 formed in the air supply pipe 10 is generally formed through a circular through hole to open downward vertically from the top of the filter bag 4, the air injection hole 12 Since the injection angle of the air injected through is generally limited to the vertical or near vertical direction, it is injected while passing in the comb direction with respect to the side of the filter bag 4 extending in the vertical direction, Since the impact effect is relatively small, and the injection air is not reached at the top of the filter bag 4, dust attached to the top of the filter bag 4 does not fall even more.

본 발명은 전술한 바와 같은 종래의 집진기의 문제점에 착안하여 제안된 것으로서, 본 발명은 간단한 구조변경을 통해 집진기에 부착된 분진들을 효과적으로 탈진시킬 수 있는 새로운 구조의 집진기를 제공하고자 하는 것이다.
The present invention has been proposed in view of the problems of the conventional dust collector as described above, the present invention is to provide a dust collector of a new structure that can effectively dust off the dust attached to the dust collector through a simple structural change.

본 발명에 따르면, 집진처리할 에어가 유입되는 유입구(7)와 집진처리된 에어가 배출되는 배출구(8)가 격판(3)에 의해 구획되도록 형성된 집진기 케이스(1)와, 이 케이스(1)의 내부에서 상기 격판(3)에서 하향연장되도록 구비되며 상부가 개방된 필터백(4)과, 상기 필터백(4)의 상부에서 대략 수평 연장되며 상기 필터백(4)의 상부에 대응하는 부위에 분사공(12)이 형성된 에어공급관(10)을 포함하는 집진기에 있어서, 상기 집진기의 분사공(12)은 곡면을 이루는 에어공급관(10)의 벽체를 따라 만곡 또는 절곡된 윤곽형태를 갖는 장공으로 이루어진 것을 특징으로 하는 집진기가 제공된다.According to the present invention, a dust collector case 1 is formed such that an inlet 7 through which air to be dust-collected and an outlet 8 through which dust-collected air is discharged are partitioned by a diaphragm 3, and the case 1; The filter bag 4 which is provided to extend downward from the diaphragm 3 in the interior of the diaphragm 3 and has a top portion which is substantially horizontally extended from the upper portion of the filter bag 4 and corresponds to the upper portion of the filter bag 4. In the dust collector including an air supply pipe 10 having an injection hole 12 formed therein, the injection hole 12 of the dust collector has a long or curved shape that is curved or bent along a wall of the air supply pipe 10 forming a curved surface. Dust collector is provided, characterized in that consisting of.

본 발명의 다른 특징에 따르면, 상기 분사공(12)은 S자형상, ㄹ자 형상, 지 그재그형상 중에서 어느 하나로 구성된 것을 특징으로 하는 집진기가 제공된다.According to another feature of the invention, the injection hole 12 is provided with a dust collector, characterized in that composed of any one of the S-shaped, r-shaped, zigzag shape.

이하에서 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다. 도 2는 본 발명에 따른 집진기이고 도 3은 이 중에서 에어공급관의 저면도로서, 도시된 바와 같이, 케이스(1)의 하단 일측에 집진처리할 에어가 유입되는 유입구(7)가 구비되고 상단 타측에는 흡입팬(9)이 장착되어 집진처리된 에어가 배출되는 배출구(8)가 구비되고, 케이스(1)의 내부에는 수평방향의 격판(3)이 구비되어 케이스(1)의 내부공간을 에어 유입측과 에어 배출측으로 구획하며, 케이스(1)의 하단에는 집진된 분진을 수집하여 배출하는 수집구(15)가 구비되고, 케이스(1)의 격판(3)에는 리테이너(2)를 둘러 싸도록 배치되는 다수의 필터백(4)이 구비되는 것은 종래의 집진기과 유사하다.Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention. Figure 2 is a dust collector according to the present invention and Figure 3 is a bottom view of the air supply pipe, as shown, the inlet 7 is provided with the inlet (7) for the air to be collected in the lower side of the case (1) A suction fan 9 is mounted on the side thereof, and a discharge port 8 through which the collected air is discharged is provided, and a horizontal diaphragm 3 is provided inside the case 1 to air the internal space of the case 1. It is divided into an inflow side and an air discharge side, and a collecting port 15 for collecting and discharging dust collected at the lower end of the case 1 is surrounded by a retainer 2 in the diaphragm 3 of the case 1. It is similar to a conventional dust collector, provided with a plurality of filter bags 4 arranged so as to be arranged.

그리고, 상기 필터백(4)의 상부는 개방되고 이 필터백(4)의 상부에 수평방형으로 연장되는 에어공급관(10)이 컴프레서(18)에 연결된다. 그런데, 이 곡면을 이루는 에어공급관(10)의 벽체를 따라 만곡된 S자 형상의 장공으로 된 분사공(12)이 형성된다. 이러한 구조에 따라, 컴프레서(18)를 통해 공급되는 압축공기가 분사공을 통해 하향 분사될 때, 수직방향으로만 분출되지 않고, 경사방향 또는 측방향으로도 분사되므로, 에어의 분사방향이 필터백(4)의 내측면의 표면에 빗방향으로 스쳐지나지 않고, 종래에 비해 필터백(4)의 내측면에 상대적으로 직각 방향에 가깝게 분사되므로, 에어분사에 의한 필터백(4)의 충격이 증대되어, 필터백(4)의 진동이 증대되고, 이에 따라 필터백(4)의 외측면에 부착된 분진 등의 탈진효과가 증대된다.An upper portion of the filter bag 4 is opened and an air supply pipe 10 extending horizontally on the upper portion of the filter bag 4 is connected to the compressor 18. By the way, the injection hole 12 of the S-shaped long hole curved along the wall of the air supply pipe 10 which comprises this curved surface is formed. According to this structure, when the compressed air supplied through the compressor 18 is injected downward through the injection hole, it is not ejected only in the vertical direction, but also in the inclined direction or the lateral direction, so that the injection direction of the air is the filter bag. Since it does not rub the surface of the inner surface of (4) in the comb direction, and is injected closer to the inside of the filter bag 4 in a right angle relative to the conventional surface, the impact of the filter bag 4 due to air spraying increases. As a result, the vibration of the filter bag 4 is increased, thereby increasing the dust-absorbing effect of dust or the like adhering to the outer surface of the filter bag 4.

또한, 곡면을 이루는 에어공급관(10)의 벽체를 따라 만곡된 장공형태의 분사공(12)이 구비되므로, 필터백(4)의 하부 뿐만 아니라 필터백(4)의 상부 내측면에도 에어의 압력이 도달되어, 필터백(4)의 상면 외측면에 부착된 분진의 탈락효율도 증대될 수 있다.In addition, since the injection hole 12 in the form of a long hole curved along the wall of the air supply pipe 10 forming a curved surface, the pressure of the air not only on the lower part of the filter bag 4 but also on the upper inner surface of the filter bag 4. With this, the dropping efficiency of the dust adhering to the upper outer surface of the filter bag 4 can also be increased.

도시된 실시예에서는 장공형태의 분사공(12)의 형태로서, S자형상을 도시하였으나, ㄹ자형상, 지그재그형상, 기타 에어분사방향을 수직하방에서 측면방향으로 더욱 유도할 수 있는 적절한 장공 형태가 채택될 수 있음은 물론이다.In the illustrated embodiment, as the form of the long hole-shaped injection hole 12, the S-shape is shown, but the appropriate long hole shape that can further guide the r-shape, zigzag shape, and other air injection direction from the vertical downward to the lateral direction Of course, it can be adopted.

이상에서 설명한 본 발명에 따르면, 집진기의 필터백(4)의 상부에 배치되는 에어공급관(10)의 저면부에 형성되는 분사공(12)의 형태를 원형과 같은 형태에서 만곡 또는 절곡된 윤곽 형태의 장공으로 변경함으로써, 탈진을 위해 분사되는 에어가 필터백(4)의 내주면에 수직방향에 가깝게 충돌하게 되어 필터백(4)의 충격을 증대시킴으로써, 탈진효과를 증대하고, 또한, 필터백(4)의 상부에 부착된 분진의 탈락효과가 증대될 수 있다.According to the present invention described above, the shape of the injection hole 12 formed in the bottom portion of the air supply pipe 10 disposed on the upper portion of the filter bag 4 of the dust collector is curved or bent in the form of a circular shape By changing to the long hole of the air, the air injected for dust removal collides with the inner circumferential surface of the filter bag 4 close to the vertical direction, thereby increasing the impact of the filter bag 4, thereby increasing the dust removal effect, and further improving the filter bag ( Dropping effect of dust attached to the upper part of 4) can be increased.
