Description

집진기 여과포의 먼지 제거장치{A Dust Removing Equipment of Dust Collection Filter}A dust removing equipment of dust collection filter

본 발명은 고로에 공급하는 바람을 생산하기 위해 청정 공기를 흡입하는 청정공기 흡입 크리닝 장치인 집진기에 관한 것으로, 더 상세하게는 청정공기 흡입 크리닝 장치인 집진기 내부에서 대기공기중의 먼지를 여과 시키는 BAG의 습식 먼지 제거장치에 관한 것이다.The present invention relates to a dust collector that is a clean air suction cleaning device that sucks clean air to produce wind to be supplied to the blast furnace, and more particularly, BAG for filtering dust in the atmospheric air inside the dust collector that is a clean air suction cleaning device. It relates to a wet dust removal device.

일반적으로 고로에 공급하는 바람을 생산하기 위해 대기공기 압축기인 송풍기 전단에는 청정 공기만을 흡입하기 위해 일정한 크기의 밀폐된 BAG실을 갖추고 그 내부에 일정한 메쉬를 가지는 BAG이 복수개 일정한 간격을 유지하며 설치되고 그 BAG 하부는 대기공기 흡입 DUCT가 설치되고 상부는 대기중의 먼지를 제거한 청정공기가 송풍기로 흡입이 되어가며, 상기한 밀폐된 BAG실 하부에는 먼지를 일시 저장하는 저장 공간과 먼지를 배출 시키는 배출구가 있다In general, in order to produce wind to be supplied to the blast furnace, the front of the blower, which is an atmospheric air compressor, is equipped with a sealed BAG chamber of a constant size to suck only clean air, and a plurality of BAGs having a constant mesh therein are installed at regular intervals. The lower part of the BAG is equipped with the air air suction duct, and the upper part of the bag is sucked into the blower with the clean air that removes the dust in the air. There is

상기한 대기 공기 중에 먼지를 제거하는 방법을 살펴보면 대기 중의 공기가 BAG실 하부의 대기 공기 흡입구로 들어오면 대기 공기중의 먼지는 BAG 외주에 부착되고, 청정공기는 BAG의 미세한 메쉬 구멍을 통해 송풍기로 흡입이 된다. 상기한 과정 중에 일정 시간 후 BAG 내부에서 일정한 압력을 가지는 공기 압력으로 BAG 내주면에 퍼지 함으로서 BAG 외주에 부착된 먼지를 BAG실 하부로 낙하시켜 포집하여In the above method of removing dust from the air, when the air enters the air intake port in the lower part of the BAG chamber, the dust in the air is attached to the outer periphery of the BAG, and the clean air is blown through the fine mesh hole of the BAG to the blower. It is inhaled. After a certain period of time during the above process, by purging the inner circumferential surface of the BAG with air pressure having a constant pressure inside the BAG, dust attached to the outer circumference of the BAG is collected and dropped to the lower part of the BAG chamber.

배출구로 배출을 시키는 것이다.It is to discharge to the outlet.

종래 방식에 의한 상기한 작업 공정 중에서 BAG 외주에 부착된 먼지를 제거하는 작업은 여과포(FILTER BAG)의 먼지(DUST) 제거 작업시 여과포가 길어 하부에 까지 일정 압력의 퍼지 압력으로 용이하게 먼지 제거가 어렵고, 대기 중의 습기 등으로 여과포(FILTER BAG) 외부 먼지와 고착이 되어 흡입 차압이 올라가게 되며 송풍기 흡입 부하 증가로 인해 전력량 손실이 발생되고 있으며, 여과포(FILTER BAG) 교체 작업 주기가 빨라져 많은 시간적 손실 및 정비비가 소요되는 문제가 있다.In the above work process according to the conventional method, the dust attached to the outer periphery of the BAG has a long filter cloth when the dust of the filter bag is removed. It is difficult, and due to moisture in the air, it is fixed with dust outside the filter bag, so the suction differential pressure rises, and power loss occurs due to the increase of the blower suction load. And there is a problem that takes maintenance costs.

본 발명은 상기와 같은 종래 제반 문제점을 해결하기 위하여 안출된 것으로 여과포(FILTER BAG)의 먼지 제거를 효율적이고 용이하게 함으로서 송풍기 흡입 차압의 상승 방지로 전력량 감소 등의 효과를 얻고, 잦은 여과포 교체로 인한 환경오염을 줄이는데 그 목적이 있다.The present invention has been devised to solve the above-mentioned problems in the prior art to efficiently and easily remove the dust of the filter bag (FILTER BAG) to obtain the effect of reducing the amount of power by preventing the rise of the blower suction differential pressure, due to frequent filter cloth replacement Its purpose is to reduce environmental pollution.

관련 도면을 참조하여 본 발명의 구성과 작용을 보다 상세히 설명하면, 도 2의 브러쉬가 부착된 먼지 제거판은 여과포(11) 외부 부착 먼지 제거를 효율적으로 하기 위하여 먼저 프라스틱 재질의 브러쉬 Roll(18)에 브러쉬(19)가 부착된 원형 Roll을 내부식성의 강한 스텐인레스 재질의 브러쉬 지지 원형(14)에 삽입 후, 브러쉬 Roll(18)과 브러쉬 Roll(18) 사이에 와셔(29)를 양쪽에 추가하므로서 브러쉬 Roll(18)이 회전이 용이하도록 한 다음,Referring to the configuration and operation of the present invention in more detail with reference to the related drawings, the brush is attached to the dust removal plate of Figure 2 in order to efficiently remove the dust attached to the filter cloth (11) first brush roll (18) of plastic material After inserting the round roll with the brush 19 attached to the brush support circle 14 made of strong corrosion resistance stainless steel, the washer 29 is added between the brush roll 18 and the brush roll 18 on both sides. Make the brush roll 18 easy to rotate, then

용접하여 2-2의 브러쉬 부착 Roll원형을 완성한다.Weld to complete 2-2 brushed roll circle.

완성된 2-2의 브러쉬 부착 Roll 원형을 도 2의 브러쉬가 부착된 먼지 제거판 처럼 용접 연결하여 완성하고, 중앙부에 원형 너트(16)를 고정하고 사각 네면에 브러쉬 지지 원형 본체 상하 이동 Roll(17)을 부착하여 도 2의 브러쉬가 부착된 먼지제거판이 상하로 이동이 용이하도록 한다.The completed 2-2 brushed roll circle of 2-2 is welded and connected like a dust removal plate attached with the brush of FIG. 2, and the circular nut 16 is fixed to the center and the brush support circular body is moved up and down on four squares. ) To facilitate the movement of the dust removal plate attached to the brush of Figure 2 up and down.

집진기 본체(1) 상부 측면에 설치된 설비를 설명하면 먼지 제거판 승하강 모터(20)와 이를 지지하는 모터 받침대(22), 모터축에 직렬로 연결된 베벨기어 원축(23)과 베벨기어 종축(24)이 맞물려 종축 나사에 도 2의 브러쉬가 부착된 먼지 제거판 중앙에 있는 원형 너트(16)와 연결시키고, 상부 리미트 스위치 L1(26)과 하부 리미트 스위치 L2(27)에 의해 먼지 제거판 승하강 모터(20)를 정회전,역회전 동작시킨다.Referring to the equipment installed on the upper side of the dust collector main body (1), the dust removal plate elevating motor 20, the motor support 22 for supporting it, the bevel gear original shaft 23 and the bevel gear longitudinal shaft 24 connected in series with the motor shaft ) Is engaged with the circular nut 16 in the center of the dust removal plate with the brush of FIG. 2 attached to the longitudinal screw, and the dust removal plate is lowered by the upper limit switch L1 (26) and the lower limit switch L2 (27). The motor 20 is rotated forward and reverse.

먼지 제거판 승하강 모터(20) 와 도 2의 브러쉬가 부착된 먼지 제거판 동작을 상세히 설명하면 Local 조작 Panel(28)의 ON 스위치를 누르면 Sequence에 따라 도 2의 브러쉬가 부착된 먼지 제거판이 상부에서 아래로 내려갔다 다시 상부로 복귀하도록 되어있는데 먼저 먼지 제거판 승하강 모터(20)가 동작하고 베벨기어 원축(23)이 회전하여 연결된 베벨기어 종축(24)도 회전하므로 종축기어에 연결된 원형너트(16)가 아래로 내려가므로 도 2의 브러쉬가 부착된 먼지 제거판도 함께 아래로 내려가면서 2-1의 여과포 먼지 제거도에 도시된 것처럼 여과포(11) 표면을 브러쉬 Roll(18)이 돌면서 먼지를 자극하여 털어주고, 다시 하부 리미트 스위치(27)에 의해 먼지 제거판 승하강 모터(20)가 역회전하여 도 2의 브러쉬가 부착된 먼지 제거판이 상승하면서 다시 한번 여과포(11) 표면을 브러쉬 Roll(18)이 돌면서 먼지를 자극, 털어주며 상부 리미트 L1(26)이 동작되면 정지하는 Sequence를 구성하고 있다.When the dust removal plate operation of the dust removal plate lifting motor 20 and the brush of FIG. 2 is described in detail, pressing the ON switch of the local operation panel 28 will cause the brush removal of the brush of FIG. And then return to the upper part. First, since the dust removal plate elevating motor 20 operates and the bevel gear original shaft 23 rotates, the connected bevel gear longitudinal axis 24 also rotates, so that the circular nut connected to the longitudinal axis gear As the (16) goes down, the brush roll (18) rotates the surface of the filter cloth (11) as shown in 2-1, and the brush roll (18) rotates the dust removal plate attached with the brush as well. Stimulates and shakes the dust removal plate up and down motor 20 again by the lower limit switch 27, and the dust removal plate attached with the brush of FIG. The brush roll 18 rotates and stimulates and shakes off dust, and constitutes a sequence that stops when the upper limit L1 26 is operated.

도 2의 브러쉬가 부착된 먼지 제거판 동작이 한번 이루어 지고 즉시 Air 분사 Line(8)에서 노즐을 통해 분사 Air(9) 약 7kg/cm2를 분사하고 하부호퍼(2)에 설치된 진동모터(6)가 동작하여 여과포(11)에서 떨어진 먼지(Dust)를 용이하게 슬라이드 게이트(4) 위에 쌓이도록 한다. 이렇게 모인 먼지(Dust)는 종전 처럼 송풍기 휴지 또는 정지시 제거한다.The dust removal plate attached to the brush of Figure 2 is performed once and immediately sprays about 7kg / cm 2 of the injection air (9) through the nozzle in the air injection line (8) and the vibration motor (6) installed in the lower hopper (2) Is operated so that the dust (Dust) dropped from the filter cloth 11 is easily accumulated on the slide gate (4). The collected dust is removed when the blower is stopped or stopped as before.

본 발명의 개선된 집진기 본체(1) 내 도 2의 브러쉬가 부착된 먼지 제거판과 먼지 제거판 승하강 모터(20)는 용이하고 효율적으로 여과포(11) 표면을 브러쉬(19)로 자극하여 먼지를 제거하므로 여과포(11) 수명향상 및 송풍기 흡입 부하감소로 전력 절감과 잦은 여과포 교체로 인한 환경오염을 방지하고 정비비를 절감하는 효과를 얻을 수 있다.In the improved dust collector main body 1 of the present invention, the brush removing dust plate and the dust removing plate lifting motor 20 of FIG. 2 easily and efficiently stimulate the surface of the filter cloth 11 with the brush 19 to remove dust. Since it eliminates the filter cloth (11) to improve the life and reduce the blower suction load, it is possible to prevent the environmental pollution due to power saving and frequent filter cloth replacement and to reduce the maintenance cost.
