Description

바이오필터식 탈취시스템{Bio-filtering system}Bio-filtering deodorization system {Bio-filtering system}

본 발명은 미생물을 이용하여 악취가스를 제거하는 바이오필터식 탈취시스템에 관한 것이다.
The present invention relates to a biofilter type deodorizing system for removing odor gas using microorganisms.

하수처리장, 슬러지 처리시설, 쓰레기 처리시설 등 각종 산업시설에서 발생하는 악취가스가 그대로 대기중으로 방출될 경우에는 악취가 발생하여 인근주민의 생활환경에 피해를 주고, 처리시설 내에서도 작업자들에게 건강상 위협이 된다.If odor gas from various industrial facilities such as sewage treatment plant, sludge treatment facility, and waste disposal facility is released into the atmosphere as it is, odor is generated, which damages the living environment of nearby residents and threatens health to workers in the treatment facility. Becomes

따라서, 악취가스에 의한 피해를 막기 위하여 악취가스가 발생하는 곳에서는 악취가스를 포집하여 정화처리한 다음 대기 중으로 배출하게 된다.Therefore, in order to prevent damage caused by odor gas, the odor gas is collected and purged and then discharged to the atmosphere.

악취가스의 처리방법에는, 활성탄을 이용하여 흡착 처리하는 물리적 방법과, 미생물을 이용하여 분해 처리하는 생물학적 방법 등이 있으며, 악취가스의 성분과 조성 및 농도, 2차오염 처리대책 등을 종합적으로 검토하여 처리방법을 선정하게 된다.Examples of the odor gas treatment include physical methods of adsorption treatment using activated carbon and biological methods of decomposition treatment using microorganisms. The odor gas composition, composition and concentration, and secondary pollution treatment measures are comprehensively reviewed. The treatment method is selected.

이중에서, 생물학적 방법을 사용하는 이른바 바이오필터식 탈취시스템은 미생물이 생육되는 담체를 사용하게 되며, 도 1에 나타난 것과 같이 상기 담체(5)가 충진되는 탈취탱크(10) 및 담체(5)에 물을 공급하기 위한 급수설비를 포함하여 이루어지는 것이 일반적이다.Among them, a so-called biofilter deodorization system using a biological method is to use a carrier on which microorganisms grow, and as shown in FIG. 1, in a deodorization tank 10 and a carrier 5 filled with the carrier 5. It is common to include a water supply facility for supplying water.

여기서, 상기 탈취탱크(10)의 내부에는 담체(5)가 충진된 탈취공간(101)의 하부에 가스유입공간(102)이 구성됨으로써 상기 가스유입공간(102)으로 유입된 악취가스가 상방으로 유동되면서 탈취공간(101)을 거치도록 구성되어 있다.Here, the gas inflow space 102 is formed in the lower portion of the deodorization space 101 filled with the carrier 5 in the deodorization tank 10, so that the odor gas introduced into the gas inflow space 102 upwards. It is configured to go through the deodorizing space 101 while flowing.

따라서, 이러한 바이오필터식 탈취시스템에 의하면 일차적으로 가스유입공간(102)에서 급수설비에 의해 분무되는 물(세정수)에 의해 악취가스에 함유된 분진 및 수용성 유해성분이 제거되는 세정작용이 이루어지고, 이어서 악취가스에 함유된 악취성분이 담체에 서식하는 미생물에 의해 분해 처리되는 탈취작용이 수행된다.Therefore, according to such a biofilter type deodorization system, a cleaning action is performed in which dust and water-soluble harmful components contained in the odor gas are first removed by water (clean water) sprayed by the water supply facility in the gas inlet space 102. Subsequently, a deodorizing action is performed in which the malodorous component contained in the malodorous gas is decomposed by a microorganism inhabiting the carrier.

그리고, 바이오필터식 탈취시스템에서 탈취탱크(10) 아래에 집수조(미도시)를 구비하고, 순환펌프(12)를 이용하여 담체(5)를 거쳐서 집수조에 모아진 물 즉, 세정수를 재사용하도록 구성되어 있는데, 악취가스의 수용성 유해성분은 대부분 산성이고, 악취가스의 일부성분은 미생물과 결합하여 산성물질을 생성하기 때문에 순환사용되는 세정수 역시 산성을 띄게 된다. In the biofilter deodorization system, a water collecting tank (not shown) is provided below the deodorizing tank 10, and the water collected in the water collecting tank through the carrier 5 is reused using the circulation pump 12, that is, the washing water is reused. Water soluble harmful components of the odor gas is mostly acidic, and some components of the odor gas combine with microorganisms to produce acidic substances, so the circulating water is also acidic.

따라서, 바이오필터식 탈취시스템에서는 산성화된 세정수를 중화하여 지속적으로 사용하기 위한 약품공급장치를 구비하고 있으며, 약품공급장치는 분말형태의 약품과 물을 혼합하여 약품용액을 형성하고 이를 저장하는 교반탱크(14)와, 상기 교반탱크(14)에 저장된 약품용액을 집수조로 공급하는 정량펌프(16)와, 집수조내에 저장된 세정수의 PH레벨을 측정하여 상기 정량펌프(16)로 신호를 전달하는 PH센서로 이루어져 있다.Therefore, the biofilter-type deodorization system is provided with a chemical supply device for neutralizing the acidified washing water for continuous use, and the chemical supply device forms a chemical solution by mixing powdered chemicals with water and stirs to store it. The tank 14, the metering pump 16 for supplying the chemical solution stored in the stirring tank 14, and the PH level of the washing water stored in the tank to measure and deliver a signal to the metering pump 16 It consists of PH sensor.

이러한 약품공급장치에서는, PH센서가 집수조에 저장된 세정수의 PH레벨을 측정하여 정량펌프(16)로 신호를 전달함에 따라, 정량펌프(16)에서는 이러한 신호에 의해 PH레벨이 기준치에 미달하면 약품용액을 집수조로 공급하는 피드백(feed back)작용을 수행함으로써 세정수가 일정한 PH레벨을 유지토록 하고 있다. In such a chemical supply device, as the PH sensor measures the PH level of the washing water stored in the sump and transmits a signal to the metering pump 16, the metering pump 16 uses the signal when the PH level is lower than the reference value. By performing a feed back action to supply the solution to the sump, the washing water is maintained at a constant PH level.

이와 같은 종래의 바이오필터식 탈취시스템은 몇가지 문제점을 가지고 있는데 이에 대해 설명하면 다음과 같다.Such a conventional biofilter type deodorization system has some problems, which will be described below.

우선, 탈취시스템의 탈취용량 및 성능을 결정하는 요인으로서는 담체(5)가 충진되는 공간 즉 탈취탱크(10)의 크기와, 탈취탱크(10)에 충진된 담체(5)의 충진밀도, 탈취탱크(10) 내를 통과하는 악취가스의 흐름상태, 담체의 형태 등이 고려된다.First, determinants of deodorizing capacity and performance of the deodorizing system include the space in which the carrier 5 is filled, that is, the size of the deodorizing tank 10, the packing density of the carrier 5 filled in the deodorizing tank 10, and the deodorizing tank. (10) The state of flow of the malodorous gas passing through the inside, the form of the carrier, and the like are considered.

이중에서 탈취탱크(10) 크기와 이에 따른 담체의 충진량은 탈취용량을 결정하는 주요 요인으로서, 탈취용량을 크게 하기 위해서는 평면적이 넓은 대용량의 탈취탱크(10)를 사용하게 되는데, 이에 따르면 탈취공간(101) 아래의 가스유입공간(102)으로 유입된 다음 위로 올라가는 악취가스의 유동특성상 가스유입공간(102)의 입구부근에 편중되어 악취가스가 위로 올라가게 되며, 가스유입공간(102) 안쪽의 깊은 곳으로는 악취가스가 원활하게 확산되지 않는다.Among these, the size of the deodorizing tank 10 and the filling amount of the carrier according to this are the main factors for determining the deodorizing capacity. In order to increase the deodorizing capacity, a large deodorizing tank 10 having a large flat area is used. 101) The odor gas is biased near the inlet of the gas inflow space 102 due to the flow characteristic of the odor gas flowing into the gas inflow space 102 below and then rises upward, and deep inside the gas inflow space 102. Odor gas does not spread smoothly.

따라서, 담체(5)가 충진된 탈취공간(101)에서도 악취가스는 일측으로 편중되어 상향이동하게 됨으로써 담체의 효율적인 사용이 이루어지지 않는다는 문제점이 있다. Therefore, even in the deodorizing space 101 filled with the carrier (5) there is a problem that the effective use of the carrier is not made because the odor gas is shifted upward to one side.

그리고, 담체(5)의 형태에 있어서는, 미생물의 생육과 악취가스와의 접촉면적 확대라는 조건을 만족하는 것이 가장 중요한 기준이 되는데, 종래의 담체는 이러한 조건만을 충족하도록 다공(多孔)특성을 가지며, 형태가 불규칙한 이른바 과립구조를 이루도록 주로 석분(石粉)을 응집하여 만들거나, 세라믹 재질의 소재로 제작되었기 때문에 구조적인 강도가 취약하다고 볼 수 있다.In the form of the carrier 5, the most important criterion is to satisfy the conditions of growth of microorganisms and expansion of the contact area with the odor gas, and the conventional carrier has a porous property so as to satisfy only these conditions. In order to form a so-called granular structure of irregular shape, it is mainly made by agglomerating stone powder (石 제작), or because it is made of a ceramic material, the structural strength is weak.

따라서, 대용량의 탈취탱크(10)에 대량의 담체(5)가 충진 적층되는 경우에는 저층부에 위치된 담체에 대하여 상층부의 담체하중으로 인한 압력이 가중되는 반면에, 담체의 구조적인 강도가 약하기 때문에 저층부의 담체가 파손되고, 파손된 담체파편이 집수조로 흘러들어가서 세정수를 순환공급하는 급수배관(28)에까지 이르게됨으로써 배관막힘현상이 유발된다는 문제점이 발생한다. Therefore, when a large amount of carriers 5 are packed and stacked in a large capacity deodorizing tank 10, the pressure due to the carrier load of the upper layer is increased with respect to the carrier located in the lower layer, whereas the structural strength of the carrier is weak. The carrier of the bottom layer is broken, and the broken carrier debris flows into the sump and reaches the water supply pipe 28 which circulates and supplies the washing water, thereby causing a blockage of the pipe.

더불어, 세정수의 중화작용을 위해 사용되는 약품은 가성소다와 같이 물에 녹아서 침전되는 성분을 포함하는 것이기 때문에 교반탱크(14)내에서 일정시간이 경과하면 용해된 약품에 의해 침전물이 형성된다는 특성을 가지고 있으며, 침전물 역시 약품용액에 포함되어 급수배관(18)을 타고 유동되기 때문에, 결과적으로 급수배관(18)내에서 침전물이 누적됨으로써 이 또한 배관막힘현상의 한 원인이 된다.In addition, since the chemicals used for the neutralization of the washing water contain components that are dissolved in water, such as caustic soda, precipitates are formed by the dissolved chemicals after a certain time in the stirring tank 14. Since the sediment is also contained in the chemical solution and flows through the water supply pipe 18, the sediment accumulates in the water supply pipe 18 as a result, which also causes a blockage of the pipe.

배관막힘현상이 발생하여 세정수의 순환공급에 차질이 발생하면, 담체에 대한 수분공급은 물론이고, 악취가스에 포함된 수용성 유해성분의 제거 또한 제대로 이루어지지 않기 때문에 탈취시스템의 기능이 저하된다는 문제점이 유발되나, 종래기술에서는 배관막힘현상의 발생여부를 즉시 파악하여 대처할 수 있도록 하는 감지수단이 없기 때문에 이로 인한 문제가 예상된다.
If a blockage occurs in the piping and the supply of water to the circulation is disrupted, not only the water supply to the carrier, but also the removal of the water-soluble harmful components contained in the odor gas are not properly performed. This is caused, but in the prior art, because there is no detection means that can immediately detect whether the phenomenon of the pipe clogging occurs, it is expected that the problem caused by this.

본 발명은 상기한 종래 문제점을 해결하고자 안출된 것으로서, 담체의 사용효율을 높이고, 배관막힘현상이 발생할 경우 이를 즉시 파악할 수 있도록 함과 동시에, 형태특성상 구조적인 강도가 향상된 담체를 포함하여 이루어짐으로써 배관막힘현상의 발생이 억제되는 바이오필터식 탈취시스템의 제공을 목적으로 한다.
The present invention has been made to solve the above-mentioned conventional problems, to improve the use efficiency of the carrier, to immediately identify when the clogging phenomenon occurs, and at the same time, by including a carrier with improved structural strength in the form characteristic pipe An object of the present invention is to provide a biofilter type deodorization system in which clogging phenomenon is suppressed.

상기 목적을 달성하기 위하여 제공되는 본 발명에 따른 바이오필터식 탈취시스템은, 담체가 충진되어 탈취작용을 수행하는 탈취공간과, 상기 탈취공간 하부에 가스유입공간을 갖는 구조로서 가스유입공간으로 유입된 악취가스가 상승하면서 탈취공간내의 담체에 의해 정화되도록 하는 탈취탱크, 상기 탈취탱크의 탈취공간으로 탈취수를 공급하는 급수배관과, 탈취공간의 아래로 흘러내린 탈취수가 모아지는 집수조와, 집수조로 모아진 탈취수를 상기 급수배관으로 공급하는 순환펌프로 구성된 급수설비를 포함하여 이루어진다. Biofilter type deodorization system according to the present invention provided to achieve the above object, the deodorization space is filled with a carrier to perform a deodorizing action, and a gas inlet space as a structure having a gas inlet space below the deodorization space flows into the gas inlet space A deodorization tank for purifying odor gas by the carrier in the deodorization space, a water supply pipe for supplying deodorization water to the deodorization space of the deodorization tank, a collecting tank for collecting deodorization water flowing down the deodorization space, and a collection tank It comprises a water supply facility consisting of a circulation pump for supplying deodorized water to the water supply pipe.

여기서, 상기 탈취탱크의 탈취공간은 다수개의 관통홀이 형성된 파티션패널에 의해 수평 구획되어 상하로 배열된 다수개의 섹션을 형성하며, 상기 각 섹션은 담체가 충진되어 만들어진 필터층과, 필터층 상방의 가스유동층으로 이루어진다.Here, the deodorization tank of the deodorization tank is horizontally partitioned by a partition panel formed with a plurality of through holes to form a plurality of sections arranged up and down, wherein each section is a filter layer formed by filling the carrier, and the gas flow layer above the filter layer Is done.

상기 탈취공간의 최하부 섹션은 세정수에 의한 세정작용만이 이루어지도록 담체가 충진되지 않는 빈 공간이 되며, 상기 탈취공간의 최하부 섹션과 가스유입공간을 구획하는 최하부 파티션패널에는 그 상면으로 흘러내린 세정수가 각각의 관통홀측으로 포집유동되도록 각각의 관통홀 주변을 감싸는 포집채널 및 상기 포집채널과 관통홀을 연결하는 공급채널이 형성된다.The lowermost section of the deodorizing space is an empty space in which the carrier is not filled so that only the cleaning action by the washing water is performed. A collecting channel surrounding each of the through holes is formed so that the number flows toward each through hole, and a supply channel connecting the collecting channel and the through hole is formed.

상기 포집채널은 관통홀 주변을 감싸도록 파여진 링형상으로 이루어지며, 상기 공급채널은 상기 포집채널보다 더욱 깊이 파여지며 포집채널에서 관통홀측으로 하향경사진 형태로 이루어진다.The collecting channel is formed in a ring shape enclosed around the through hole, and the supply channel is deeper than the collecting channel and is inclined downward from the collecting channel.

상기 최하부 파티션패널의 각 관통홀은 하단에서 중심부로 가면서 그 단면적이 점차 감소되었다가 중심부를 지나 상단으로 가면서 단면적이 점차 확대되는 벤투리관 형태로 이루어진다.Each through hole of the lower partition panel is formed in a venturi tube shape in which the cross-sectional area gradually decreases from the bottom to the center, and then gradually increases in cross-section as it passes through the center to the top.

상기 담체는 원주형으로서, 다수개의 통기홀이 길이방향으로 형성되어 규칙적으로 배열된 벌집형태로 이루어진다.
The carrier is columnar, and has a plurality of vent holes formed in a longitudinal direction to form a honeycomb arranged regularly.

이상에서 살펴본 바와 같이 본 발명에 따른 바이오필터식 탈취시스템에 의하면 최하부 파티션패널의 형태 특성상 세정수에 의한 세정작용이 효율적으로 이루어지며, 악취가스가 탈취탱크 내에서 필터층의 전면적과 고르게 접하게 됨으로써 담체의 사용효율이 향상됨으로써 결과적으로 탈취성능의 향상을 기대할 수 있다.
As described above, according to the biofilter type deodorizing system according to the present invention, the cleaning function is efficiently performed by the washing water due to the shape of the lower partition panel, and the odor gas is brought into contact with the entire area of the filter layer in the deodorizing tank. As the use efficiency is improved, the deodorization performance can be improved as a result.

이하, 본 발명을 실시하기 위한 구체적인 내용을 첨부된 도 2부터 도 5 까지 참조로 하여 상세하게 설명한다. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 2 to 5.

본 발명에 따르면, 도 2에 나타난 것과 같이 상기 탈취탱크(30)의 탈취공간 내부(301)는 다공성(多孔性) 파티션패널(32)에 의해 수평으로 구획되어 상하로 배열된 다수개의 섹션을 형성하고, 상기 각 섹션은 담체(7)가 충진되어 만들어진 필터층(30a)과, 필터층 상방의 가스유동층(30b)이 구분형성되도록 이루어진다.According to the present invention, as shown in FIG. 2, the interior 301 of the deodorization tank 30 is horizontally partitioned by the porous partition panel 32 to form a plurality of sections arranged up and down. Each section is formed so that the filter layer 30a formed by filling the carrier 7 and the gas flow layer 30b above the filter layer are formed separately.

여기서, 각 섹션에는 그 적층높이가 섹션 전체의 높이에 못미치도록 담체(7)가 충진됨으로써 각 섹션은 필터층(30a)과 그 상방의 가스유동층(30b)으로 이루어진다.Here, each section is filled with a carrier 7 so that its stacking height is less than the height of the whole section, so that each section is composed of a filter layer 30a and a gas flow layer 30b above it.

그리고, 상기 탈취공간(301)의 최하부 섹션(303)은 세정수에 의한 세정작용만이 이루어지도록 담체가 충진되지 않는 빈 공간이 된다.In addition, the lowermost section 303 of the deodorizing space 301 becomes an empty space in which the carrier is not filled so that only the cleaning action by the washing water is performed.

여기서, 도 3에 나타난 것과 같이 상기 담체(7)는 예시적으로, 원주형태이며 다수개의 통기홀(7a)이 길이방향으로 형성되어 규칙적으로 배열된 벌집형태로 이루어지는 것이 바람직한데, 이에 따르면 담체(7)의 구조적인 강도가 높아지고, 일정한 형태의 기체 흐름을 유도함과 동시에 기체와의 접촉면적이 확대된다.Here, as shown in FIG. 3, the carrier 7 is exemplarily circumferentially formed, and a plurality of vent holes 7a are formed in a longitudinal direction and preferably formed in a honeycomb form regularly arranged. The structural strength of 7) is increased, and the contact area with the gas is expanded while inducing a certain form of gas flow.

상기 파티션패널(32)은 전술한 바와 같이 다공성 즉, 다수개의 관통홀이 갖추어진 구조로 이루어지는데, 상기 관통홀은 서로간의 간격이 조밀하여 기체의 유동에 큰 지장을 주지 않을 뿐만 아니라, 그 직경이 담체의 크기보다 작아서 담체가 아래로 빠지지 않도록 구성된다. The partition panel 32 is porous as described above, that is, the structure is provided with a plurality of through holes, the through holes are not close to each other due to the close spacing of the gas flow, as well as its diameter It is configured to be smaller than the size of the carrier so that the carrier does not fall down.

그리고, 특히 도 4에 나타난 것과 같이 상기 탈취공간(301)의 최하부 섹션(303)과 가스유입공간(302) 사이에 배치된 최하부 파티션패널(33)에는 그 상면으로 흘러내린 세정수가 각각의 관통홀(33a)측으로 포집유동되도록 각각의 관통홀(33a) 주변을 감싸는 포집채널(33b) 및 상기 포집채널(33b)과 관통홀(33a)을 연결하는 공급채널(33c)이 형성된다.In particular, as shown in FIG. 4, in the lower partition panel 33 disposed between the lowermost section 303 and the gas inflow space 302 of the deodorizing space 301, the washing water flowing down to the upper surface of each of the through holes is provided. A collection channel 33b surrounding the periphery of the through hole 33a and a supply channel 33c connecting the collection channel 33b and the through hole 33a are formed to collect flow toward the 33a side.

여기서, 상기 포집채널(33b)은 관통홀(33a) 주변을 감싸도록 일정 깊이로 파여진 링형상으로 이루어지며, 상기 공급채널(33c)은 상기 포집채널(33b)보다 더욱 깊이 파여지며 포집채널(33b)에서 관통홀(33a)측으로 하향경사진 형태로 이루어지는데, 상기 포집채널(33b)은 일정 간격을 두고 복수개가 형성될 수 도 있다.Here, the collecting channel 33b is formed in a ring shape which is dug to a predetermined depth so as to surround the perforation hole 33a, and the supply channel 33c is deeper than the collecting channel 33b and collects the collecting channel ( It is formed in the form inclined downward toward the through hole (33a) in 33b, a plurality of collecting channels 33b may be formed at a predetermined interval.

상기 최하부 파티션패널(33)의 각 관통홀(33a)은 하단에서 중심부로 가면서 그 단면적이 점차 감소되었다가 중심부를 지나 상단으로 가면서 단면적이 점차 확대되는 벤투리관 형태로 이루어진다.(도 5 참조) Each through hole 33a of the lower partition panel 33 is formed in the shape of a venturi tube in which the cross-sectional area gradually decreases as it goes from the bottom to the center and then gradually increases in cross-section as it passes through the center to the top (see FIG. 5).

또한, 본 발명에 의한 탈취시스템은, 급수배관(18)이 이물질에 의해 막혀서 세정수의 순환이 제대로 이루어지지 않는 경우에, 이러한 배관막힘현상의 발생을 즉시 파악할 수 있도록 하는 순환점검수단을 포함하여 이루어지는 것이 바람직하다.In addition, the deodorization system according to the present invention includes a circulation check means for immediately grasping the occurrence of such clogging phenomenon when the water supply pipe 18 is blocked by foreign substances and circulation of the washing water is not properly performed. It is preferable to make.

순환점검수단으로서는 급수배관상에 장착되는 유량계(40)와 유속계(42) 등을 포함하여 이루어질 수 있다.
The circulation inspection means may include a flow meter 40 and a flow meter 42 and the like mounted on the water supply pipe.

상술한 바와 같은 본 발명에 따른 바이오필터식 탈취시스템의 작용을 설명하면 다음과 같다.Referring to the operation of the biofilter-type deodorization system according to the present invention as described above are as follows.

먼저, 탈취탱크(30)의 가스유입공간(302)으로 유입된 악취가스는 위로 올라가면서 탈취공간(301)의 최하부 섹션(303)으로 유입되는데, 이때 악취가스는 도 5에 나타난 것과 같이 최하부 파티션패널(33)을 통과하는 과정에서 벤투리관 형태로 이루어진 관통홀(33a)의 형태특성상 가속 유동되며, 관통홀(33a)의 상단에서 확산된다.First, the malodorous gas introduced into the gas inlet space 302 of the deodorizing tank 30 flows up into the lowermost section 303 of the deodorizing space 301, where the malodorous gas is the lowest partition as shown in FIG. 5. In the course of passing through the panel 33, the flow is accelerated due to the shape of the through-hole 33a having a venturi tube shape, and is diffused at the upper end of the through-hole 33a.

그리고, 상기 탈취공간(301)의 상부에서 지속적으로 공급됨으로써 각 섹션을 거친 다음, 최하부 파티션패널(33)의 상면에 떨어지게 되는 세정수는 관통홀(33a)의 주변에 형성된 포집채널(33b)로 흘러들어가 모아지게 되고, 상기 포집채널(33b)에서 모아진 세정수는 다시 공급채널(33c)을 통해 관통홀(33a)측으로 유동된다.Then, the water is continuously supplied from the upper portion of the deodorizing space 301, and after passing through each section, the washing water falling on the upper surface of the lower partition panel 33 is collected into the collecting channel 33b around the through hole 33a. The water is collected and collected, and the washing water collected in the collecting channel 33b flows to the through hole 33a through the supply channel 33c.

상기 공급채널(33c)을 통해 관통홀(33a)측으로 유동된 세정수는 관통홀(33a)에 이르러서는 가속된 악취가스에 의해 타격됨으로써 최하부 섹션(303)내로 분무되며 그 입자가 미세하게 파열 분산된다.The washing water flowing to the through hole 33a through the supply channel 33c is sprayed into the lowermost section 303 by being blown by the accelerated odor gas reaching the through hole 33a, and the particles are ruptured finely. do.

따라서, 최하부 섹션(303)에서는 악취가스에 대하여 아래에서 위로 분무되는 세정수에 의한 강력한 세정작용과 위에서 아래로 흘러내리는 세정수에 의한 세정작용이 복합적으로 이루어진다.Therefore, in the lowermost section 303, a strong washing action by the washing water sprayed from the bottom to the odor gas and a washing action by the washing water flowing from the top to the bottom are combined.

한편 여기서, 포집채널(33b) 및 공급채널(33c)이 갖추어지지 않고, 세정수가 관통홀(33a)의 전(全)방향에서 분산되어 관통홀(33a)로 유입되는 경우를 가정하여 보면 세정수가 분산유입되는 만큼, 본 발명에서와 같이 포집채널(33b)과 공급채널(33c)이 구비된 특성상 관통홀(33a) 측으로 유입되는 세정수의 흐름이 일측방향으로 집중되는 경우에 비해 악취가스에 의한 세정수의 타격효과가 감소되는 것을 예상할 수 있다. On the other hand, here, when the collecting channel 33b and the supply channel 33c is not provided, and the washing water is dispersed in all directions of the through hole 33a and flows into the through hole 33a, the washing water is introduced. As the dispersion is introduced, due to the characteristics of the collecting channel 33b and the supply channel 33c as in the present invention, the flow of the washing water flowing into the through hole 33a is concentrated due to odor gas. It can be expected that the impact of washing water is reduced.

계속해서, 최하부 섹션(303)을 거쳐 상방으로 유동되는 악취가스는 각 필터층과 필터층 사이의 가스유동층을 반복적으로 통과하면서 담체(7)에 의한 탈취작용 및 세정수에 의한 세정작용을 거치게 되며, 가스유동층으로 유입되는 과정에서 넓게 분산 혼류된다.Subsequently, the malodorous gas flowing upward through the lowermost section 303 passes through the gas flow layer between each filter layer and the filter layer and undergoes a deodorizing action by the carrier 7 and a washing action by the washing water. In the course of entering the fluidized bed, it is widely dispersed and mixed.

이에 따라 본 발명에 의하면 결과적으로 악취가스가 가스유입공간(302)의 입구와 가까운곳에 편중되지 않고 필터층의 전면적과 고르게 접하게 됨으로써 담체 사용의 효율이 향상된다.Accordingly, according to the present invention, as a result, the odor gas is contacted evenly with the entire surface of the filter layer without being biased near the inlet of the gas inflow space 302, thereby improving the efficiency of using the carrier.

더불어, 담체(7)가 탈취공간(301) 내에서 각 섹션별로 나뉘어서 파티션패널(32)에 의해 지지되는 특성상 담체(7)의 하중압력 또한 분산되기 때문에 담체(7)가 하중압력에 의해 파손되는 현상이 크게 감소하게 되며, 담체(7)의 파편으로 인해 급수배관(18)이 막히는 배관막힘현상도 감소하게 된다. In addition, since the carrier 7 is divided by each section in the deodorizing space 301 and the load pressure of the carrier 7 is also dispersed due to the characteristics supported by the partition panel 32, the carrier 7 is damaged by the load pressure. The phenomenon is greatly reduced, and the blockage of the pipes in which the water supply pipe 18 is blocked due to the fragments of the carrier 7 is also reduced.

한편, 세정수 중화 약품으로 인한 침전물의 발생으로 세정수의 순환에 지장이 초래될 우려는 여전하다고 볼 수 있으나, 세정수의 순환에 문제가 발생하게 되면, 세정수의 유동형태가 정상상태에서와 크게 달라지며 이러한 상황이 유량계(40)와 유속계(42)를 통하여 즉시 파악되므로 즉각적인 대처가 가능하게 된다.
On the other hand, there is still a concern that the generation of sediment due to the neutralizing chemicals in the washing water may interfere with the circulation of the washing water, but if a problem occurs in the washing water circulation, Significantly different and this situation is immediately identified through the flow meter 40 and the flow meter 42, it is possible to respond immediately.
