일반적으로 농수산 부산물과 같은 음식물 쓰레기를 처리하기 위해 음식물 쓰레기 처리장치가 사용된다. 이러한 음식물 쓰레기 처리장치는 음식물 쓰레기를 소각하거나, 화학적 방식으로 처리하거나, 생물학적 방식 등으로 처리하고 있다. 이중, 생물학적 방식을 이용하는 음식물 쓰레기 처리장치는 미생물을 이용하여 발효, 분해하도록 구성된다. 즉, 음식물 쓰레기와 호기성 미생물을 접종한 바이오칩의 혼합물을 교반기에 투입하고 전기나 가스 등을 이용하는 가열수단으로 공기와 같은 유체를 가열하여 열기를 공급함과 동시에 지속적으로 교반(혼합) 함으로써 호기성 미생물들에 의해 음식물 쓰레기가 교반기 내부에서 분해되도록 구성된다.In general, a food waste disposal device is used to treat food waste such as agricultural and fishery by-products. Such food waste disposal apparatuses incinerate food waste, treat it in a chemical manner, or treat it in a biological manner. Among them, a food waste disposal apparatus using a biological method is configured to ferment and decompose using microorganisms. In other words, a mixture of food waste and biochips inoculated with aerobic microorganisms is put into a stirrer, and a fluid such as air is heated with a heating means using electricity or gas to supply heat and at the same time, the aerobic microorganisms are continuously stirred (mixed). It is configured such that the food waste is decomposed inside the stirrer.

[실시예 1] [Example 1]
도 1 내지 도 4에 도시된 바와 같이 본 발명에 따른 탈취장치(100)의 바람직한 실시예 1을 설명하면 다음과 같다.Referring to a preferred embodiment 1 of the deodorizing apparatus 100 according to the present invention as shown in Figures 1 to 4 as follows.
상기 탈취장치(100)는 악취 성분을 포함하는 폐가스를 가열하여 악취 성분을 열분해시키는 히터(110)와, 상기 히터(110)의 일 측에 배치된 열교환기(120)와, 상기 열교환기(120)의 일 측에 배치된 폐가스 유동수단(130)으로 대별되어 이루어진다.The deodorizing device 100 includes a heater 110 for thermally decomposing odor components by heating waste gas containing odor components, a heat exchanger 120 disposed at one side of the heater 110, and the heat exchanger 120 ) Is made roughly divided into the waste gas flow means 130 disposed on one side of the.
상기 히터(heater)(110)는 악취 성분을 포함하는 폐가스를 가열하여 악취 성분을 열분해시키기 위한 것으로서, 저항선 등에 전류를 흘려 발생하는 열을 직접 이용하는 전열기 또는 저항로, 전기난로 전기풍로 등과 같은 전기적인 히터, 가스를 이용하는 가스히터, 온수를 이용하는 온수히터 등 다양한 히터를 이용할 수 있다.The heater 110 is for thermally decomposing the odor component by heating the waste gas containing the odor component, and is an electric heater or a resistance furnace that directly uses heat generated by passing an electric current through a resistance wire, an electric stove, an electric stove, etc. Various heaters, such as a heater, a gas heater using gas, and a hot water heater using hot water, can be used.
또, 상기 히터(110)는 일 측에 폐가스 유입부(111)가 형성되고 타 일측에는 폐가스 배출부(112)가 형성된다.In addition, the heater 110 is formed with a waste gas inlet 111 on one side and a waste gas discharge 112 on the other side.
또한, 상기 히터(110)는 상기 열교환기(120)를 통해 열교환이 이루어진 후 유입되는 폐가스의 온도 변화에 따라 동작시간을 달리 하도록 온도 센서(temperature sensor)를 구비하는 것이 바람직하다.In addition, the heater 110 is preferably provided with a temperature sensor (temperature sensor) to vary the operating time according to the temperature change of the incoming waste gas after heat exchange is performed through the heat exchanger 120.
예컨대, 상기 폐가스에 포함된 악취 성분을 열분해시키기 위한 히터(110)의 가열온도가 300℃ 이고, 상기 열교환기(120)를 통해 열교환이 이루어진 후, 히터(110)의 폐가스 유입부(111)로 유입되는 폐가스의 온도가 온도 센서에 의해 200℃ 로 감지된 경우, 상기 히터(110)는 폐가스에 포함된 악취 성분을 열분해하기 위한 가열 온도를 300℃가 아닌 100℃만 더 높이도록 작동하도록 제어된다.For example, the heating temperature of the heater 110 for pyrolyzing the odor components contained in the waste gas is 300°C, and after heat exchange is performed through the heat exchanger 120, the waste gas inlet 111 of the heater 110 When the temperature of the incoming waste gas is sensed at 200°C by the temperature sensor, the heater 110 is controlled to increase the heating temperature for pyrolyzing the odor components contained in the waste gas by only 100°C instead of 300°C. .
따라서, 본 발명은 히터(110)의 동작시간을 줄이고 악취 성분을 열분해시키기 위한 가열온도를 종래에 비해 조금만 높이면 되므로 열분해에 필요한 에너지 소모량을 현저하게 줄일 수 있기 때문에 비용도 현저하게 절감할 수 있다.Accordingly, in the present invention, since the operating time of the heater 110 is reduced and the heating temperature for pyrolyzing the odor component is only slightly increased compared to the prior art, energy consumption required for pyrolysis can be remarkably reduced, and thus cost can be significantly reduced.
또한, 상기 히터(110)의 동작시간과 악취 성분을 열분해시키기 위한 가열온도는 배출되는 폐가스의 종류와 악취 성분에 따라 다르게 설정할 수 있다.In addition, the operating time of the heater 110 and the heating temperature for pyrolyzing the odor component may be set differently depending on the type of waste gas discharged and the odor component.
그리고, 상기 히터(110)의 폐가스 유입부(111)로 유입되어 높은 온도로 열분해된 폐가스는 폐가스 배출부(112)를 통과하여 상기 열교환기(120)의 내부를 유동하면서 열교환이 이루어져 배출된다.In addition, the waste gas introduced into the waste gas inlet 111 of the heater 110 and pyrolyzed at a high temperature passes through the waste gas discharge unit 112 and flows through the heat exchanger 120 to perform heat exchange and discharge.
상기 열교환기(120)는 내부에 공간을 구비한 용기(121)와 상기 용기(121)의 일 측에 형성된 폐가스 유입구(122)와, 상기 용기(121)의 타측에 형성된 폐가스 배출구(123)와, 상기 용기(121)의 내부에 연장되게 배치되는 1 이상의 관형상의 열교환관(124)을 포함하여 구성된다.The heat exchanger 120 includes a container 121 having a space therein, a waste gas inlet 122 formed on one side of the container 121, a waste gas outlet 123 formed on the other side of the container 121, and , It is configured to include one or more tubular heat exchange tubes 124 disposed to extend inside the container 121.
여기서, 상기 열교환기(120)의 내부 공간에는 유입되는 폐가스의 흐름을 전체로 고르게 유도하여 원활한 열교환을 이루도록 복수 개의 격벽(125)이 지그재그 형태로 형성된다.Here, in the inner space of the heat exchanger 120, a plurality of partition walls 125 are formed in a zigzag shape to achieve smooth heat exchange by evenly guiding the flow of the introduced waste gas to the whole.
상기 폐가스 유입구(122)는 음식물 쓰레기 처리장치(200)와 연결되어 음식물 쓰레기 처리시 발생하는 폐가스를 열교환기(120)의 내부 공간으로 유입되도록 한다. 이때 유입된 폐가스는 도 2에 도시된 것과 같이 상기 열교환관(124) 내를 유동하는 가스와의 접촉이 차단된 상태로, 용기(121) 내를 유동하면서 열교환관(124)에 의해 가열될 수 있다.The waste gas inlet 122 is connected to the food waste treatment device 200 to allow waste gas generated during the treatment of food waste to flow into the inner space of the heat exchanger 120. At this time, the introduced waste gas may be heated by the heat exchange tube 124 while flowing in the container 121 in a state in which contact with the gas flowing in the heat exchange tube 124 is blocked as shown in FIG. have.
또한, 상기 폐가스 유입구(122)와 음식물 쓰레기 처리장치(200) 사이에는 필터(122a)를 형성하는 것이 바람직하다.In addition, it is preferable to form a filter 122a between the waste gas inlet 122 and the food waste treatment device 200.
즉, 상기 필터(122a)를 형성함에 따라 음식물 쓰레기 처리장치(200)를 통해 배출되는 폐가스에 포함된 미세한 이물질이 걸러지도록 함으로써 열교환기(120)의 내부 공간을 오염시키지 않고 폐가스의 원활한 흐름을 이룰 수 있다.That is, as the filter 122a is formed, fine foreign substances contained in the waste gas discharged through the food waste treatment device 200 are filtered, thereby achieving a smooth flow of the waste gas without polluting the internal space of the heat exchanger 120. I can.
상기 폐가스 배출구(123)는 상기 히터(110)의 폐가스 유입부(111)와 연결된다.The waste gas outlet 123 is connected to the waste gas inlet 111 of the heater 110.
그리고 상기 열교환관(124)의 일단은 상기 히터(110)의 폐가스 배출부(112)와 연결되고, 타단은 상기 폐가스 유동수단(130)과 연결된다.In addition, one end of the heat exchange tube 124 is connected to the waste gas discharge unit 112 of the heater 110, and the other end is connected to the waste gas flow means 130.
상기 폐가스 유동수단(130)은 공기의 유동을 일으키는 팬(fan)으로, 상기 열교환기(120)의 열교환관(124)을 통해 배출되는 폐가스를 외부로 원활하게 배기시키기 위해 흡입로(131)와 배기로(132)를 구비한다.The waste gas flow means 130 is a fan that causes the flow of air, and includes a suction path 131 and a suction path 131 to smoothly exhaust the waste gas discharged through the heat exchange pipe 124 of the heat exchanger 120 to the outside. It is provided with an exhaust path 132.
상기 폐가스 유동수단(130)의 흡입로(131)는 열교환관(124)과 연결되고, 배기로(132)는 도 4에 도시된 것과 같이 미세먼지 제거를 위한 별도의 습식탈취조(140)와 연결되는 것이 바람직하다.The suction path 131 of the waste gas flow means 130 is connected to the heat exchange tube 124, and the exhaust path 132 includes a separate wet deodorization tank 140 for removing fine dust as shown in FIG. It is desirable to be connected.
이와 같은 구성의 본 발명에 따른 탈취장치(100)는 상기 폐가스 유동수단(130)인 팬이 동작하게 되면 상기 열교환관(124)의 일단과 연결된 흡입로(131)에 의해 폐가스가 빨려들게 된다.In the deodorizing apparatus 100 according to the present invention having such a configuration, when the fan serving as the waste gas flow means 130 is operated, the waste gas is sucked in by the suction path 131 connected to one end of the heat exchange tube 124.
즉, 상기 열교환관(124)의 일단과 연결된 흡입로(131)에 의해 음식물 쓰레기 처리장치(200)로부터 발생된 폐가스가 폐가스 유입구(122)를 통해 열교환기(120)의 내부 공간으로 유입된다.That is, the waste gas generated from the food waste treatment apparatus 200 by the suction path 131 connected to one end of the heat exchange tube 124 is introduced into the internal space of the heat exchanger 120 through the waste gas inlet 122.
이때, 상기 음식물 쓰레기 처리장치(200)에서 배출되는 폐가스의 온도는 약 50℃∼60℃ 정도이다.At this time, the temperature of the waste gas discharged from the food waste treatment apparatus 200 is about 50°C to 60°C.
그리고, 상기 열교환기(120)의 내부 공간으로 유입된 폐가스는 각 격판(125)을 거쳐 상기 히터(110)의 폐가스 유입부(111)와 연결되는 폐가스 배출구(123)로 배출된다.In addition, the waste gas introduced into the inner space of the heat exchanger 120 is discharged through each diaphragm 125 to the waste gas outlet 123 connected to the waste gas inlet 111 of the heater 110.
이때, 상기 폐가스는 열교환관(124)을 통해 배출되는 고온의 폐가스와 열교환이 이루어지게 된다.In this case, the waste gas is heat-exchanged with the high-temperature waste gas discharged through the heat exchange tube 124.
여기서, 상기 열교환관(124)을 통해 배출되는 고온의 폐가스와 열교환이 이루어지는 폐가스의 온도는 약 150℃∼200℃까지 가열된다.Here, the temperature of the high-temperature waste gas discharged through the heat exchange tube 124 and the waste gas for heat exchange is heated to about 150°C to 200°C.
