Description

아스콘 출하장용 분진, 악취 저감설비{DUST AND OFFENSIVE ODOR REDUCING DEVICE FOR ASCON OUTPUT PLACE IN ASCON PLANT}Dust and odor reduction equipment for ascon shipping sites {DUST AND OFFENSIVE ODOR REDUCING DEVICE FOR ASCON OUTPUT PLACE IN ASCON PLANT}

본 발명은 아스콘 출하장에 대기 중인 트럭에 아스콘 플랜트에서 제조한 아스콘을 적재하는 과정에서 발생하는 분진과 유해가스가 포함된 악취를 더욱 효율적으로 제거할 수 있는 아스콘 플랜트의 아스콘 출하장용 분진, 악취 저감설비에 관한 것이다. The present invention is to reduce dust and odors for ascon shipping sites of ascon plants that can more efficiently remove odors including dust and harmful gases generated in the process of loading ascon manufactured by ascon plants in trucks waiting at ascon shipping sites It is about equipment.

아스콘 플랜트는 도 1에 예시한 바와 같이 규격별로 골재를 저장하다가 드라이어로 공급하는 콜드 빈(a), 콜드 빈(a)에서 투하되는 골재를 드라이어로 운반하여 투입하는 피더-수평 컨베이어-경사 컨베이어로 이뤄진 골재 이송수단(b), 투입되는 골재를 가열하여 건조하는 드라이어(c), 드라이어에서 건조되어 나오는 골재를 진동스크린으로 이송하는 핫 엘리베이터(d), 핫 컨베이어에 실려 온 건조 골재에서 입도별로 분류하는 진동스크린(e), 이후 핫 빈(f)을 거쳐 스케일 호퍼(g)로 계량하여 믹서(h)로 보내 공급되는 아스팔트 피치와 혼합하여 아스콘을 생산하는 것이다. As exemplified in FIG. 1, the ascon plant is a feeder-horizontal conveyor-inclined conveyor that transports and inputs the aggregates dropped from the cold bin (a) and the aggregates dropped from the cold bin (a) to the dryer while storing aggregates by standard. Aggregate transfer means (b) achieved, dryer (c) to heat and dry the aggregate to be fed, hot elevator (d) to transfer aggregates dried from the dryer to a vibrating screen, and classify by particle size from dry aggregates loaded on a hot conveyor Ascon is produced by weighing with a scale hopper (g) through a vibrating screen (e) and then a hot bean (f) and mixing it with the asphalt pitch supplied to the mixer (h).

아스콘 제조과정에서 골재의 이송과 아스팔트 피치 믹싱과정에서는 더스트 등의 분진이 날리고 악취와 유해가스도 발생한다. 분진과 악취, 유해가스는 아스콘 플랜트 인근에 거주하는 주민과의 마찰등 민원발생의 요인이 되어 그 해결책의 일환으로 집진설비와 악취제거수단 등을 설계에 반영하였다. In the process of transporting aggregate and mixing asphalt pitch in the ascon manufacturing process, dust such as dust is blown out, and odors and harmful gases are also generated. Dust, odors, and harmful gases became a factor in the occurrence of civil complaints such as friction with residents living near the asphalt concrete plant, and dust collection facilities and odor removal measures were reflected in the design as part of the solution.

그간, 아스콘 플랜트에서 발생하는 분진, 악취, 유해가스로 인한 폐해를 근절하기 위한 제안이 있었다. 그 중에서 참고할 만한 몇 가지 사례를 든다. In the meantime, there have been proposals to eradicate the harmful effects of dust, odor, and harmful gas generated in the asphalt concrete plant. Among them, some examples worth referencing are given.

등록특허 제10-1129599호는 폐아스콘의 골재를 가열해 녹일 때 발생하는 유분, 분진, 악취 등이 백 필터로 유입되기 전에 배기관 상에 설치된 소형 연소기를 경유하도록 해 유분과 분진, 악취 등을 연소시켜 제거함으로써 백 필터의 기계적 수명 단축을 지연시키게 한 것으로, 아스콘 출하장의 분진, 악취, 유해가스 제거와는 거리가 멀다. Registration Patent No. 10-1129599 burns oil, dust, and odor by passing through a small combustor installed on the exhaust pipe before the oil, dust, and odor generated when the aggregate of waste ascon is heated and melted into the bag filter. This is to delay the reduction of the mechanical life of the bag filter by removing it by using it, and it is far from removing dust, odors, and harmful gases at the Ascon factory.

등록특허 제10-1273329호도 참고하기에 충분하다. 이 선행기술은 아스콘 수송차량이 진입하여 대기하는 아스콘 출하장에서 출입구를 제외한 3면에 벽을 세우고, 측벽의 상단에 형성된 흡기구로 출하장내 공기를 흡입하여 여과 집진부로 보내 여과하는 이를테면 복잡한 설비로 포집하여 활성탄 집진기를 통해 배출하는 설비로서 고가의 유지비용이 발생하여 실용성이 낮다. Registered Patent No. 10-1273329 is sufficient for reference. This prior art is a complex facility that erects walls on three sides except for the entrance at the Ascon shipping area where Ascon transport vehicles enter and waits, and intakes air in the shipping area through an inlet formed at the top of the sidewall and sends it to the filtering dust collection unit for filtering. As a result, it is a facility that discharges through an activated carbon dust collector, resulting in expensive maintenance costs and low practicality.

이 선행기술과 일맥상통하는 등록특허 제10-1834139호도 있다. 이 선행기술은 믹서 내부에서 발생하는 분진과 유해가스, 악취와 믹서의 아스콘 배출부로 아스콘을 출하하는 과정에서 발생하는 분진과 유해가스 및 악취를 흡기팬으로 흡입하여 백 필터에서 여과하고, 백필터와 흡기팬 사이에서 오존으로 유해가스를 분해한 후 활성탄 흡착탑이 주체인 유해가스 저감장치를 경유한 뒤 드라이어로 환송해 연소시키는 것이다. There is also a registered patent No. 10-1834139 in line with this prior art. In this prior art, dust, harmful gas, and odor generated inside the mixer, and the dust, harmful gas, and odor generated in the process of shipping ascon to the ascon outlet of the mixer are inhaled through an intake fan and filtered through a bag filter, and a bag filter and an intake fan. After decomposing harmful gas with ozone, it is returned to the dryer for combustion after passing through the harmful gas reduction device, which is the main body of the activated carbon adsorption tower.

상기 설비 또한 현장에서 실용적이지 못해 사용에 성공적이지 못한 효율성 및 유지비용 관점에서 재검토할 필요가 있다. The facility is also impractical in the field and needs to be reviewed in terms of efficiency and maintenance costs, which are not successful in use.

본 발명은 아스콘 출하장에 대기 중인 트럭에 생산된 아스콘을 적재하는 과정에서 발생하는 분진과 유해가스가 포함된 악취를 보다 효율적으로 제거하여 저감시키는 설비를 제공하려는 것이다. The present invention is to provide a facility that more efficiently removes and reduces odors including dust and harmful gases generated in the process of loading ascon produced in a truck waiting at an ascon shipping site.

위 과제를 달성하기 위한 본 발명은 철제 서포트로 구성된 기존의 출하장을 트럭 진입구만 제외한 양 측면과 후면 및 상부를 막아 믹서에서 아스콘 출하 시에 발생하는 비산 먼지와 악취 및 유해가스가 흡기덕트로 용이하게 흡입되도록 유도하고, 출하장과 드라이어용 버너팬을 연결하는 흡입덕트 상에 스트레이너(집진기. 이하 스트레이너로 통일함)와 저압형 흡출기를 설치하여 출하장 내의 분진과 악취 및 유해가스를 흡출해 제거함으로써 이물질이 드라이어용 버너팬에 미칠 악영향을 배제하고, 스트레이너를 통과한 악취 및 유해가스를 재연소하여 저감시키는 아스콘 플랜트의 아스콘 출하장용 분진 및 악취 저감설비를 제안한다. The present invention for achieving the above problem is to block both sides, rear, and upper portions of the existing shipping site consisting of iron supports except for the truck entrance, so that scattering dust, odors and harmful gases generated when ascon is shipped from the mixer are easily used by the intake duct. It induces to be inhaled properly, and by installing a strainer (dust collector, hereinafter referred to as a strainer) and a low-pressure type suction device on the suction duct that connects the burner fan to the shipping site, it absorbs and removes dust, odor and harmful gases in the shipping site. By doing so, we propose a dust and odor reduction facility for the Ascon factory in the Ascon plant that eliminates the adverse effects of foreign substances on the burner fan for dryers, and reduces odors and harmful gases that have passed through the strainer by reburning.

트럭 출입구를 제외하고 측면과 후면 및 상면이 막힌 아스콘 출하장에서 발생하는 분진 등의 이물질을 저압 흡출기의 흡인력으로 스트레이너에 도입하여 제거한 후의 악취와 유해가스를 드라이어용 버너팬으로 보내 재연소함으로써 분진 및 악취를 매우 효과적으로 제거, 저감시킬 수 있다. Excluding the entrance of the truck, foreign substances such as dust generated at the side, rear and top of the blocked asphalt concrete are introduced into the strainer with the suction power of the low-pressure suction machine, and the odor and harmful gas after removal are sent to the burner fan for the dryer to be burned again. And it can very effectively remove and reduce odor .

도 2는 본 발명에 의한 아스콘 출하장(1)의 투시도이고, 도 3은 그 종단측면도이다, 아스콘 출하장(1)은 통상의 아스콘 플랜트의 하부에 설치된다. 본 발명은 아스콘 출하장(1)은 트럭 출입구(2)만 남긴 채 출하장(1)의 경계를 따라 양 측벽(3)과 뒷벽(4) 및 상부에 지붕(5)을 설치하여 아스콘 출하 시에 발생하는 분진과 악취, 유증기 등이 옆과 뒤 및 위로 확산되는 것을 극력 억제한다. FIG. 2 is a perspective view of an asphalt concrete shipping site 1 according to the present invention, and FIG. 3 is a longitudinal side view thereof. The asphalt concrete shipping site 1 is installed under a normal asphalt concrete plant. In the present invention, the asphalt concrete shipping site (1) is provided with a roof (5) on both side walls (3) and rear walls (4) and the upper part along the boundary of the shipping site (1) leaving only the truck entrance (2). It suppresses the spread of dust, odor, oil vapor, etc. generated in the side, back and up as much as possible.

또, 뒷벽(4)과 지붕(5)에는 출하장(1) 내의 공기를 흡출하기 위한 후드(6)가 설치되어 있고, 상기 후드(6)는 흡기덕트(7)로 스트레이너(9)에 연결하며, 흡기덕트(7) 상에서 스트레이너(9)의 후방에는 저압 흡출기(8)를 설치한다.Also, with the back wall (4) On the roof (5) A hood (6) is installed to suck out the air in the shipping area (1), and the hood (6) is connected to the strainer (9) by an intake duct (7), and the strainer (9) on the intake duct (7) A low-pressure suction machine (8) is installed at the rear of the machine.

출하장(1) 내에 떠돌다가 분진과 악취, 유증기는 후드(5)를 통해 저압 흡출기(8)에 의해 흡인되어 흡기덕트(7)를 타고 스트레이너(9)로 유입되며, 스트레이너(9)를 통과하면서 이물질과 더스트가 제거되고, 스트레이너(9)에서 미처 걸러지지 못한 채 빠져나가는 초미립 더스트와 악취 및 유해가스는 드라이어(10)의 버너팬(11)으로 보내서 재연소시킨다. While floating in the shipping area (1), dust, odor, and oil vapor are sucked through the hood (5) by the low-pressure suction device (8), and flow into the strainer (9) through the intake duct (7), and the strainer (9) is As they pass through, foreign matter and dust are removed, and ultrafine dust that escapes without being filtered out of the strainer (9) The odor and harmful gases are sent to the burner fan 11 of the dryer 10 for reburn.

상기 지붕(5)에도 후드(6a,)를 설치하여 흡기덕트(7)에 연결해 출하장 내 분진과 악취 및 유해기스 제거의 효율성을 높인다. 도면 부호 (13)은 지붕(5)에 뚫은 믹서의 아스콘 배출용 믹서 게이트공이다.The hood 6a is also installed on the roof 5 and connected to the intake duct 7 to increase the efficiency of removing dust, odors, and harmful gases in the shipping site. Reference numeral 13 denotes a mixer gate hole for discharging asphalt concrete from the mixer drilled in the roof 5.

한편, 출하장(1)의 출입구(2)에서 윗인방에 커튼(12)을 설치하여 입고된 트럭 운전석의 뒤쪽 윗공간을 최소화함으로써 윗인방 쪽 공간을 통해 분진과 악취, 유증기가 출입구(2) 밖으로 새어 나가지 못하게 한다. On the other hand, by installing a curtain 12 in the upper room at the entrance (2) of the shipping area (1), dust, odors, and vapors are transmitted through the upper room by minimizing the space behind the driver's seat of the truck. Do not let it leak out.

커튼(12)은 분진과 유증기가 달라붙기 어렵고 수세하기도 용이하며, 트럭이 드나들 때 트럭에 외상을 입히지 않고, 적재된 아스콘에 접촉하더라도 긁어서 떨어뜨리지 않을 정도의 유연성을 지닌 합성수지 시트 또는 고무 시트가 제격이다. The curtain 12 is made of a synthetic resin sheet or rubber sheet that is flexible enough to prevent dust and oil vapor from sticking to each other and is easy to wash, and does not inflict trauma to the truck when the truck enters or exits, and does not scratch and drop even if it touches the loaded asphalt concrete. That's right.

이상의 설명은 이제까지 예의검토한 것 중에서 가장 바람직하고 현실성이 있다고 여긴 실시예에 바탕한 것으로, 이에 한정하는 것은 아니며, 본 발명의 기술적 사상에서 벗어나지 않는 범위 내에서 일부 구성 요소를 등가성을 가진 요소로 대체하거나, 부가적 기능을 추가하는 등의 변경도 본 발명의 기술적 범주에 속하는 것으로 이해해야 한다.
