일반적으로 종래의 반응조는 일정한 공간에서 물질전달력을 향상시키기 위하여 반응조 내부에 혼합장치(mixer)를 설치하여 물질반응 효율을 높여 왔으며, 효율의 상승을 위하여 혼합장치의 구조 개선, 즉 임펠러(impeller)의 구조 개선이나 혼합장치의 동력을 강화하였다. 뿐만 아니라 종래에는 처리 대상물질의 양이 많으면 반응조의 규모를 확장하여 단위 처리용량을 늘려 왔다. 그러나 이러한 종래의 기술은 초기 투자비의 증폭과 운영비의 증대 등 경제적이 부담이 유발되었으며, 반응조 용량의 증대에 따라 설치 공간이 늘어나게 되는 문제점이 있다.In general, the conventional reactor has been improved the efficiency of the material reaction by installing a mixer inside the reactor in order to improve the mass transfer capacity in a certain space, and improve the structure of the mixing device, namely impeller (impeller) to increase the efficiency Improved the structure and strengthened the power of the mixing device.

본 발명은 일정한 공간 내에서 물질반응을 위하여 반응조(반응기)를 설치할 경우 반응조의 내부에 배플을 설치하여 반응조 안에 유입된 물질의 처리효율을 높이기 위한 반응조의 구조 개선에 관한 기술이다.The present invention is a technique for improving the structure of the reaction vessel to increase the treatment efficiency of the substances introduced into the reaction tank by installing a baffle inside the reaction vessel for the reaction in a certain space for the reaction (reactor).

본 발명은 유체공정이 행하여지는 반응조의 내부에 소정 크기의 배플을 상기 반응조 내주면과의 사이에 소정 폭의 외측 유동영역이 유지되고, 상기 반응조의 저면과의 사이에 통로가 유지되며, 수면과의 사이에 통로가 유지되도록 설치하고, 상기 반응조의 외측 유동영역과 대향되는 내측 영역에 폭기 시스템이 배치되도록 설치하여, 폭기되어 유동되는 유체가 배플의 주위를 선회하면서 대류되어 상기 반응조의 벽면에서 발생하는 사류를 방지함으로써 물질전달력을 높이고 반응효율을 향상시키도록 구성된다.According to the present invention, a baffle having a predetermined size is disposed inside a reaction tank in which a fluid process is performed, and an outer flow area of a predetermined width is maintained between the inner circumferential surface of the reaction tank, and a passage is maintained between the bottom of the reaction tank, It is installed so that the passage is maintained therebetween, and the aeration system is disposed in an inner region opposed to the outer flow region of the reactor, and the aerated fluid flows around the baffle to convex to be generated at the wall surface of the reactor. It is configured to increase the mass transfer capacity and improve the reaction efficiency by preventing the turbulence.

구체적으로 본 발명은 반응조 내부에 배플을 설치함으로써 반응조 안에서의 대류 현상을 촉진시키고, 물질반응에서 물질 전달을 위하여 물질 간의 접촉 및 혼합(mixing)을 유도할 경우 반응조의 벽면에서 발생할 수 있는 사류를 방지하여 전달력(효율)을 높임으로써 반응효과를 상승시키며, 뿐만 아니라 이를 통하여 반응시간을 단축함으로써 반응조의 규모를 축소할 수 있는 설비 장치의 개선에 관한 것이다.Specifically, the present invention promotes convection in the reactor by installing a baffle inside the reactor, and prevents turbulence that may occur on the wall of the reactor when inducing contact and mixing between materials for mass transfer in the material reaction. To increase the reaction effect by increasing the transfer force (efficiency), as well as to improve the equipment to reduce the size of the reactor by reducing the reaction time through it.

본 발명은 같은 용량의 반응조에서 내부에 설치한 배출을 통하여 사류를 방지함으로써 물질전달 효율을 높였으며, 동일한 혼합장치일 경우에 배플을 이용한 대류현상을 유도함으로써 장치의 효율을 높였다. 뿐만 아니라 반응조의 용량은 물질전달 효율을 상승시킴으로써 반응조에서의 체류시간(HRT; holding reactor time)을 감소시킬 수 있으며, 따라서 동일한 처리량에 대하여 축소된 반응조의 규모로 대처할 수 있게 되었다.The present invention improves the mass transfer efficiency by preventing turbulence through the discharge installed inside the reactor of the same capacity, and in the same mixing apparatus, induces convection using baffles to increase the efficiency of the apparatus. In addition, the capacity of the reactor can reduce the holding reactor time (HRT) in the reactor by increasing the mass transfer efficiency, and thus can cope with the scale of the reactor for the same throughput.

일반적으로 반응조는 미생물의 배양을 위하여 실험실용으로 사용되고 있는 소형의 생물 배양기로부터 중화학 공업의 플랜트에 이르기까지 다양한 규모와 크기 및 디자인이 있다. 또 반응조는 환경분야, 화학공업, 생명산업분야 등 다양한 분야에 걸쳐 활용되고 있고, 물질전달이나 물질대사 등 반응공정에서 목표한 반응 효과를 얻음으로써 오염물질의 처리, 물질생산 등의 목적을 달성하기 위한 장치 도구로 활용된다.In general, reactors come in a variety of sizes, sizes and designs, ranging from small biological incubators used in the laboratory for the cultivation of microorganisms to plants in the heavy chemical industry. In addition, the reactor is used in various fields such as environment, chemical industry, life industry, etc., and achieves the target reaction effect in the reaction process such as material transfer or metabolism to achieve the purpose of treating pollutants and producing materials. It is utilized as a device tool for.

활용의 일 예로 환경분야의 수질정화에서 산화반응조의 경우 산화반응조는 물 속에 함유되어 있는 생분해성 유기질을 호기성 상태에서 산화분해하고 암모니아성 질소나 유기질 질소 등을 질산화하는 공정이 행해진다. 질산화를 유도하는 질산화균은 생장속도가 일반 호기성균 보다 느린 불리한 생장조건을 가지고 있으므로 반응조에서 질산화 효율을 높이기 위하여 반응조에 미생물 담체를 투입하여 미생물의 밀도를 높인다.For example, in the case of the oxidation reaction tank in the water purification of the environmental field, the oxidation reaction tank oxidizes the biodegradable organic matter contained in the water in an aerobic state and nitrifies the ammonia nitrogen or the organic nitrogen. Nitrifying bacteria that induce nitrification have adverse growth conditions with slower growth rates than normal aerobic bacteria, and thus increase the density of microorganisms by introducing microbial carriers into the reactor to increase nitrification efficiency.

이때 질산화 반응은 호기성 상태에서 진행되므로 폭기장치를 도입하여 산화반응조 속의 용존산소 농도를 충분히 높이고, 특히 이때 반응조가 폭기 시스템에 의한 물의 대류현상을 촉진하고 사류를 방지하기 위하여 본 발명에 따라 반응조 내부에 한쪽 부분을 설정하여 반응조의 바깥방향으로 양쪽에 배플을 설치하여 활용한다.At this time, since nitrification proceeds in an aerobic state, an aeration apparatus is introduced to sufficiently increase the dissolved oxygen concentration in the oxidation reaction tank, and in this case, the reaction tank is used inside the reactor according to the present invention to promote convection of water by the aeration system and to prevent turbulence. One part is set and baffles are installed on both sides in the outward direction of the reactor.

도 1은 본 발명의 일 실시예에 의한 배플이 설치된 반응조의 부분 종단면도를 보인 것이고, 도 2는 본 발명의 일 실시예에 의한 배플이 설치된 반응조의 부분 평면도를 보인 것으로, 도면에는 본 발명에 따라 반응조(1)의 내부에 배플(2)을 설치한 형태가 예시되어 있다.Figure 1 shows a partial longitudinal cross-sectional view of a reaction tank equipped with a baffle according to an embodiment of the present invention, Figure 2 shows a partial plan view of the reaction tank equipped with a baffle according to an embodiment of the present invention, Therefore, the form which installed the baffle 2 in the inside of the reaction tank 1 is illustrated.

상기 배플(2)의 규격은 반응조(1)의 전체 규격을 고려하여 적당한 크기로 하고, 배플(2)의 상단 끝은 수표면에서 적당하게 낮게 설치하여 폭기 시스템에 의해 상부로 이송된 물이 정체됨이 없이 하단으로 이송될 수 있도록 조의 규격에 맞추어 설치하며, 동시에 폭기 시스템에 의하여 반응조(1) 내부의 물이 연속공정으로 상부로 이동할 때 후속으로 이송되는 물이 먼저 이송된 물이 반응조의 하단으로 이송되는 것을 방해하지 않게 그 하부에 물의 이송경로가 확보되도록 설치한다.The size of the baffle (2) is a suitable size in consideration of the overall size of the reaction tank (1), the upper end of the baffle (2) is installed on the water surface moderately low, the water transferred to the upper by the aeration system stagnated It is installed according to the standard of the tank so that it can be transported to the bottom without being made. At the same time, when the water inside the reaction tank 1 is moved to the upper part in a continuous process by the aeration system, the water to be transferred first is transferred to the bottom of the reaction tank. It is installed so that the transport path of water is secured at the lower part thereof so as not to interfere with the transport.

이때 폭기 시스템은 배플(2)이 설치된 공간 안에서만 물질이동을 할 수 있도록 설치한다.At this time, the aeration system is installed so that the material movement only in the space where the baffle (2) is installed.

배플(2)의 재료는 반응조와 동일한 재질을 이용할 수 있으며, 별도의 재질을 이용하여 조의 벽체에 고정하는 방식으로 설비할 수도 있다.The material of the baffle 2 may use the same material as the reaction tank, and may be installed in a manner of fixing to the wall of the bath using a separate material.

그리고, 상기 배플(2)은 반응조(1)의 용적을 기준으로 약 5∼35%의 크기로설치되고, 반응조(1)의 심도를 기준으로 약 5∼20%의 크기로 설치하는 것이 바람직하다.In addition, the baffle 2 is installed at a size of about 5 to 35% based on the volume of the reaction tank 1, and is preferably installed at a size of about 5 to 20% based on the depth of the reaction tank 1. .

도면에서 미설명 부호 3은 스틸 그레이트, 4는 담체를 보인 것이고, 5는 폭기 시스템을 보인 것이다.In the drawings, reference numeral 3 denotes a steel great, 4 denotes a carrier, and 5 denotes an aeration system.

이와 같이 하면, 반응조(1) 안에서 예를 들어 물과 같은 유체가 반응조(1)의 하부에 설치되는 폭기 시스템에 의해 폭기되어 도면에 화살표로 표시한 바와 같이 양쪽 배플(2)의 주위로 대류되어 물질전달이 활발하게 되고, 사류의 발생이 최대한 방지되며, 폭기조에서의 체류시간(HRT)을 줄일 수 있으므로 폭기 효율을 향상시키고 폭기조의 규모도 축소시킬 수 있다.In this way, a fluid such as, for example, water in the reactor 1 is aerated by an aeration system installed in the lower part of the reactor 1 and convexed around both baffles 2 as indicated by arrows in the figure. Material transfer is active, the occurrence of crossflow is prevented as much as possible, and the residence time (HRT) in the aeration tank can be reduced, so that the aeration efficiency can be improved and the size of the aeration tank can be reduced.

그리고, 수질 정화를 위하여 배플을 설치한 반응조는 표준 활성오니법과 반응조에 담체를 충진한 경우에 적용할 수 있다.In addition, a reaction tank provided with a baffle for water purification can be applied to a standard activated sludge process and a carrier filled with a reaction tank.

반응조 내부에 배플을 설치한 경우의 경제성은 배플 설치비 만큼 초기 투자비가 늘어나지만 폭기 효율의 증대를 통한 반응조 크기의 감소와 폭기장치의 정격용량 감소 등에 의해 초기투자비의 절감과 소용량의 폭기장치 운영을 통한 비용과 에너지 절감, 등의 전체투자비용을 줄이고 운영비를 절감시킬 수 있다. 뿐만 아니라 폭기 시스템에 대하여 에너지, 소음, 진동 등을 고려할 때에 보다 친환경적인 공법이다.If the baffle is installed inside the reactor, the initial investment cost is increased as the baffle installation cost, but the initial investment cost is reduced by the reduction of reactor size and the rated capacity of the aerator by increasing the aeration efficiency. It can reduce the total investment cost such as cost, energy saving, etc. and reduce the operating cost. In addition, it is a more environmentally friendly method when considering energy, noise, vibration, etc. for the aeration system.

이러한 배플 시스템은 각 공정의 반응조에서 대상물질의 순환이나 대류를 필요로 하는 경우에 적용할 수 있다. 즉 대상물질이 유동성을 지니고 있고, 일정한 반응조 내에서 물질전달력이 공정반응 효율과 관련이 있는 경우에 적용할 수 있다.Such a baffle system can be applied in the case of requiring circulation or convection of the target material in the reactor of each process. That is, it can be applied when the target material has fluidity and the mass transfer ability is related to the process reaction efficiency in a certain reactor.

배플의 구조는 반응조의 구조에 따라 원형, 사각형으로 형성되고, 사각형이나 다각형 구조의 반응조에서는 배플의 수가 외벽의 수에 따라 하나 이상 다수가 형성될 수 있다.The structure of the baffle is formed in a circle, a square according to the structure of the reaction tank, in the reaction tank of the square or polygonal structure, the number of baffles may be formed one or more depending on the number of outer walls.

이상에서 설명한 바와 같은 본 발명은 유체공정에서 반응조를 이용한 공정을 대상으로 반응의 효율을 높이기 위하여 반응조의 내부에 배플을 설치하여 반응조 내에서 유체간의 물질전달 효율을 높이고 이를 통하여 반응조의 규모를 축소할 수 있고, 반응효율을 높이기 위하여 반응조에 부차적으로 설치되는 장치들의 효율을 증대시킬 수 있으며, 이에 따른 정격 감소 등을 통하여 초기투자비를 절약할 수 있는 경제적인 이익과 에너지 절감, 소음 및 진동의 감소 등을 통하여 환경을 개선할 수 있다.The present invention as described above is to install a baffle in the reaction tank to increase the efficiency of the reaction for the process using the reaction tank in the fluid process to increase the material transfer efficiency between the fluid in the reaction tank and thereby to reduce the scale of the reaction tank It is possible to increase the efficiency of the devices installed in the reactor secondary to increase the reaction efficiency, and the economic benefits and energy savings, noise and vibration reduction that can save the initial investment cost by reducing the rating accordingly Through this, the environment can be improved.

따라서, 이와 같은 본 발명은 배양기, 공기정화조, 수질정화조, 석유화학 등의 산업 각 분야에서 이용되는 각종의 반응조에 매우 유리하게 적용할 수 있다.Therefore, the present invention can be very advantageously applied to various reaction tanks used in industrial fields such as incubators, air purification tanks, water purification tanks, and petrochemicals.
