Abstract

A deodorizing apparatus is provided to remove odor sources contained in a harmful gas collected by a bag filter, thereby improving factory environment and removing odor from gas exhausted to the air, by using activated carbon and lime powder. A pre-duster(4) is installed at a front end of a bag filter(6) to keep the efficiency of dust collection of the bag filter. The pre-duster compulsorily inputs lime powder thereinto to minimize the load of the bag filter, which is caused by increasing the amount of dust collection. A powder supply device(5) and a powder reproduction device(10) are installed to remove odor sources, which are not filtered out by the bag filter and discharged to the air. Further, the powder supply device contains a powder storing-hoper, a level switch, a rotary valve, a ring blower and a transfer pipe.

가스가 집진기를 통해 대기중으로 배출되어 유발시키는 악취를 효과적으로 제거하는데 그 목적이 있다.    The purpose is to effectively remove the odor caused by the gas discharged into the atmosphere through the dust collector.

현재 공장에서 발생된 가스는 집진기(bag filter)를 사용하여 포집은 하고있으나, 악취를 유발시키는 성분은 제거되지 않은 상태로 대기중에 배출되고 있다.    At present, the gas generated in the factory is collected by using a bag filter, but the odor causing component is discharged to the atmosphere without being removed.

대기중에 배출된 악취가 주변 민가로 유입되고 민원이 자주 발생되어 공장측과 환경에 관한 대책협의가 이루어지고 있으나 뚜렷한 해결방법이 제시되어져 있지 못하다.Odors released into the atmosphere flow into the surrounding private houses and complaints frequently occur, and discussions with the factory about the environment have been made, but no clear solution has been proposed.

종래의 공장에서 발생하는 악취제거 장치에는 활성탄 흡착탑(AC tower)과 악취제거 스프레이탑 등이 있다. Odor removal apparatus generated in the conventional factory includes an activated carbon adsorption tower (AC tower) and odor removal spray tower.

활성탄 흡착탑의 경우 배기가스에 활성탄 분진이 함유되어 배출되므로 분진배출을 방지하기위해서는 흡착탑 다음에 집진기를 설치해야하므로 이중의 설치비용이 발생하고 활성탄의 교체주기가 짧아 교체비용과 함께 작업인원이 투입되어 인건비가 발생하며, 흡착탑 내부에서 작업이 이루어져 작업원의 안전에도 위험성이 내재되어있다.In the case of activated carbon adsorption tower, activated carbon dust is discharged in exhaust gas, so dust collector must be installed after adsorption tower to prevent dust emission. Therefore, double installation cost is incurred and replacement cycle of activated carbon is short. Labor costs are incurred and work is carried out inside the adsorption tower, which poses a risk to the safety of the workers.

악취제거 스프레이탑의 경우 중화제로 화학약품을 사용하게되어, 약품사용량 조절에 문제가 발생하였을 경우에는 화학약품이 대기중으로 배출되어 2차오염으로 이루어지며, 폐수처리 설비가 부대적으로 필요하게 되어서, 최근에는 거의 사용하지않고 있다.In the case of odor removal spray tower, chemicals are used as neutralizers, and when there is a problem in controlling the amount of chemicals used, the chemicals are discharged into the air, which is composed of secondary pollution, and waste water treatment facilities are additionally needed. Recently rarely used.

본 발명은 공장에서 발생하는 악취를 기존에 설치되어있는 집진기에 적용시켜 1차적으로 미분을 포집하여 집진효율의 저하를 방지하면서, 구조적으로 안전하며 최소의 비용으로 탈취가능한 장치를 제공하는데 있다. The present invention is to provide a device that is structurally safe and deodorizing at a minimum cost while applying the odor generated in the factory to the dust collector installed in the existing to collect the fine powder to prevent the reduction of dust collection efficiency.

본 발명은, 통상의 집진기(bag filter)(6)에 분체공급장치(5)와 분체재생장치(10)를 설치하고, 분체를 리사이클(recycle)시켜 사용주기를 극대화시키므로서 런닝코스트(running cost) 절감효과를 가져온다.     The present invention provides a running cost by installing a powder supply device 5 and a powder regeneration device 10 in a conventional bag filter 6 and recycling the powder to maximize the use cycle. ) It brings saving effect.

집진기(bag filter)(6) 앞단 덕트관로에 분체공급장치(5)로 활성탄과 소석회의 혼합된 분체를 투입하여 악취유발 성분을 흡착시킨다.The mixed powder of activated carbon and slaked lime is introduced into the duct pipe in front of the bag filter 6 to adsorb the malodor causing component.

악취유발 성분이 흡착된 분체는 집진기(bag filter)(6)의 휠터(filter)(7)에 의해 분리된다.The powder on which the malodor-causing component is adsorbed is separated by a filter 7 of a bag filter 6.

펄스젯(pulse jet)(8) 방식으로 탈진되어진 분체는 집진호퍼(hoper)(9)로 포집되어져 그대로 배출되는 것이 일반적이나, 본 발명은 스크류콘베어(screw conveyor)(10-1)를 이용하여 탈진되어진 분체를 분체재생장치(10)로 이송시킨다.The powder dedusted by the pulse jet (8) method is generally collected by the dust collection hopper (9) and discharged as it is, but the present invention uses a screw conveyor (10-1) The dedusted powder is transferred to the powder regeneration device 10.

분체재생장치(10)에 축척된 분체는 다시 집진 덕트(duct)로 이송되어 리사이클(recycle)되어진다.The powder accumulated in the powder regeneration apparatus 10 is transferred to a dust collecting duct and recycled.

일정기간동안 순환되어진 분체는 스크류콘베어(screw conveyor)(10-1)를 역회전(전기적 신호의 변환으로 가능함)시켜 최종적으로 배출(11)시킨다.The powder circulated for a certain period of time rotates the screw conveyor (10-1) reversely (possible by the conversion of the electrical signal) and finally discharged (11).

최종배출(11)을 하기 바로 전 단계에서 새로운 분체를 투입시킨다.Fresh powder is added just before the final discharge (11).

집진기 휠터를 통과한 가스는 악취성분이 제거되어 있으므로 청정공기로서 대기중으로 배출되어진다.The gas passing through the dust collector filter is discharged to the atmosphere as clean air because the odor component is removed.

본 발명이 적용되는 기계적 부분은 활성탄과 소석회를 혼합한 분체를 공급시켜주는 장치(5)와 집진기 호퍼(9)에 포집되어진 분체를 재생시켜주는 장치(10)로 구분할수있으며, 엔지니어링(engineering)적 부분은 분체를 강제 투입시켜 집진량의 증가에 따른 집진기의 부하(load)를 줄여주는 프레더스터(pre-duster)(4)를 집진기(6) 앞단에 설치하는 것으로 설명할수있다.The mechanical part to which the present invention is applied can be divided into an apparatus 5 for supplying powder mixed with activated carbon and slaked lime, and an apparatus 10 for regenerating powder collected in the dust collector hopper 9, and engineering.
