연속식 활성탄 제조장치{Equipment for continuously making active carbon}Equipment for continuously making activated carbon {Equipment for continuously making active carbon}

본 발명은 연속식 활성탄 제조장치에 관한 것으로서, 더욱 상세하게는 활성탄 제조장치로 널리 사용되는 연속식 킬른장치를 구성하고 있는 탄화용 킬른로와 가스 활성화용 킬론로의 열 공급구조 및 열 순환구조를 개량하여, 최소한의 연료가스로 최단시간에 연속식 킬른장치의 내부온도를 안정시킴으로써 고품질의 활성탄을 제조할 수 있는 연속식 활성탄 제조장치에 관한 것이다.The present invention relates to a continuous activated carbon production apparatus, and more particularly, a heat supply structure and a thermal circulation structure of a carbonization kiln and a gas activation kelon, which constitute a continuous kiln apparatus widely used as an activated carbon production apparatus. The present invention relates to a continuous activated carbon production apparatus capable of producing high quality activated carbon by improving the internal temperature of the continuous kiln apparatus in the shortest time with the least fuel gas.

일반적으로 산업화에 의한 각종 물질문명의 발달된 도시지역에서는 인구집중과 각종 시설물들이 밀집되어 환경오염에 의한 대기 중의 공기가 심각하게 오염되어 도시지역에 생활하는 많은 사람들의 건강에 많은 위험이 상존하여 왔고, 이에 공기 중의 함유되는 각종 유해물질을 제거하기 위한 공기정화기술이 많이 개발되어 왔는데, 특히 다공질의 탄소 결정체에서 인체에 유익하지 않은 각종 유해물질이 흡착되어 주변 공기를 정화시키는 활성탄의 성능이 알려지면서 여러 형태의 활성탄이 개발되어 왔다.
In general, in urban areas where various material civilizations are developed by industrialization, population concentrations and various facilities are concentrated, and the air pollution caused by environmental pollution is seriously contaminated, and there are many risks to the health of many people living in urban areas. As a result, many air purification technologies have been developed to remove various harmful substances contained in the air. Especially, the ability of activated carbon to purify the surrounding air by adsorbing various harmful substances which are not beneficial to the human body in porous carbon crystals is known. Several types of activated carbon have been developed.

최근에 가장 보편적으로 사용되고 있는 가스활성화법을 이용한 활성탄의 제조공정은 활성탄의 원료가 되는 유기물을 600~800℃의 범위에서 가열하여 유기물에 포함되어 있는 휘발성 조직은 연소시키고 탄소결정체로 조직화된 탄화물(탄화숯)을 생성하는 탄화공정과, 스팀가스(수증기)등과 같은 가스 촉매제가 첨가된 상기 탄화숯을 800~1100℃의 범위에서 재 가열하여 미세한 다공질의 흡착탄을 생성하는 활성화 공정으로 구분할 수 있고, 상기와 같이 가스활성화법을 이용한 대부분의 활성탄은 공지의 구조로 되어 있는 일반적인 킬른장치[연소가스 공급부, 원료투입구, 탄화용 킬른로, 가스 촉매제를 첨가시켜 가스활성화 반응으로 활성탄을 생성하는 활성화용 킬른로, 가스배출구 등으로 구성되어 있음]를 이용하여 제조되고 있음을 알 수 있다.
In the manufacturing process of activated carbon using gas activation method, which is the most commonly used gas, the organic material, which is the raw material of activated carbon, is heated in the range of 600 ~ 800 ° C, and the volatile tissues contained in the organic material are burned and carbides are formed into carbon crystals. Carbonization process to generate charcoal), and activated carbon reheating the carbonized charcoal to which a gas catalyst such as steam gas (water vapor) is added in the range of 800 to 1100 ° C. to generate fine porous adsorbed carbon. Most of the activated carbon using the gas activation method as described above is a general kiln device having a known structure [combustion gas supply unit, raw material inlet, carbonization kiln, activation for generating activated carbon by a gas activation reaction by adding a gas catalyst. Consisting of a kiln, a gas outlet, and the like].

한편 흡착성이 우수한 활성탄은 탄소결정체에 대한 조직이 파괴되지 않으면서 탄화물의 외표면에 보다 많은 공극을 형성시켜 단위 면적당 표면적이 최대로 되어야 함은 주지의 사실에 해당한다 할 것이고, 고품질의 활성탄을 제조하기 위하여서는 무엇보다도 상기 킬른장치를 구성하고 있는 탄화용 제1 킬른로 및 가스활성화용 제2 킬른로의 내부가 적정한 온도로 일정하게 유지되어야 할 것인바, 상기 각 킬른로에 대한 충분한 예열공정이 필연적으로 요구되어야 할 것이다.
On the other hand, activated carbon, which has good adsorption properties, is known to have a larger surface area per unit area by forming more voids on the outer surface of the carbide without destroying the structure of the carbon crystals. In order to do this, first of all, the interior of the first kiln for carbonization and the second kiln for gas activation, which constitute the kiln apparatus, should be kept at a constant temperature. It will necessarily be required.

또한 상기 킬른장치를 이용하여 활성탄을 제조하기 위하여서는 내부온도가 고온으로 유지되어야 하는 탄화용 킬른로와 가스 활성화용 킬른로의 특성상 대량의 활성탄을 동시에 가열할 수 있도록 로(爐)의 길이가 일정규모 이상으로 길게 구성되어 있는 일반적이다.
In addition, in order to manufacture activated carbon using the kiln apparatus, the length of the furnace is constant so that a large amount of activated carbon can be simultaneously heated due to the characteristics of the carbonization kiln furnace and gas activation kiln furnace, in which the internal temperature must be maintained at a high temperature. It is generally composed of more than scale.

그런데 종래에 일반적인 연속식 킬른장치를 구성하고 있는 가열로와 가스활성화로의 경우 그 내부온도를 가열할 수 있는 연소가스의 투입구가 어느 한쪽으로만 형성되어 있는 바, 길이가 길게 형성되어 있는 로(爐)의 내부 전체를 일정온도로 유지시키기 위한 예열공정의 단계에서부터 많은 시간과 연소가스가 소모됨에 따라 생산성과 경제성이 떨어지는 문제점이 있었다. 이에 일부에서는 상기 예열공정을 생략한 채 연료가스를 대량으로 상기 로(爐)에 공급하여 급속하게 가열된 탄화물로 활성탄을 제조하여 사용하고 있으나, 로(爐)의 내부온도가 불균일한 상태에서 제조된 탄화물에 형성되는 공극이 불안정하게 형성되어 활성탄의 품질이 저하되는 문제점이 발생하게 되었던 것이다.
However, in the case of a heating furnace and a gas activating furnace which constitute a conventional continuous kiln device, a furnace having a long length is formed in one of the inlet ports of the combustion gas capable of heating the internal temperature thereof. I) There was a problem in that productivity and economical efficiency were deteriorated as a lot of time and combustion gas were consumed from the preheating step to maintain the entire interior at a constant temperature. In some cases, the preheating process is omitted, and the fuel gas is supplied to the furnace in large quantities to produce activated carbon from rapidly heated carbide, but the furnace is manufactured in a non-uniform temperature. The voids formed in the carbides are unstable, which causes a problem of degrading the quality of activated carbon.

다른 한편 활성탄의 원료가 되는 탄화물이 추출되는 탄화장치를 구성하는 탄화용 킬른로와, 상기 탄화물과 가스촉매를 반응시켜 다공질의 활성탄을 추출하는 가스활성화용 킬른로가 별도의 구성으로 분리되어 있는 일반적인 연속식 킬른장치와는 달리, 최근에는 가스활성화로만으로 탄화로에 의한 탄화공정과 가스활성화로로에 의한 가스활성화공정을 동시에 수행할 수 있는 단일 종류의 로(爐)를 이용한 여러형태의 킬른장치들이 선행기술로 제시된 바 있다.
On the other hand, the carbonization kiln furnace constituting the carbonization apparatus for extracting carbide as a raw material of activated carbon and the gas activation kiln furnace for extracting porous activated carbon by reacting the carbide with the gas catalyst are separated into a general configuration. Unlike the continuous kiln system, several types of kilns using a single type of furnace which can perform the carbonization process by the carbonization furnace and the gas activation process by the gas activation furnace in recent years are only gas activation furnaces. Have been presented as prior art.

그런데 위와 같이 단일 종류의 로(爐)를 이용한 각 킬른장치들은 하나의 로(爐)에서 추출된 탄화물을 냉각시켜 일부는 착화용 숯으로 사용하고 나머지는 활성탄의 원료로 하여 또 다시 탄화물을 추출한 로(爐)에 공급시켜 재 가열을 통하여 활성탄으로 제조하게 되는 바, 이는 냉각된 탄화물을 고온으로 상승시키는 데 많은 연료가스가 새롭게 공급되어야 함으로써 불필요한 연료가 투입되어야 하는 문제점이 있었던 것이다.
However, as above, each kiln device using a single type of furnace cools carbides extracted from one furnace, some of them are used as ignition charcoal, and others are raw materials of activated carbon. Since it is supplied to (iii) and made of activated carbon through reheating, this is a problem in that unnecessary fuel has to be introduced since a large amount of fuel gas must be newly supplied to raise the cooled carbide to a high temperature.

또 다른 한편 종래의 일반적인 킬른장치를 통해 배출되는 배기가스에는 인해에 유해한 각종 오염물질이 함유되어 있는 바, 상기 배출가스에 함유된 각종 오염물질들이 공기 중에 비산됨으로써 인체 건강에 많은 유해함이 존재하고 있었던 것이다.On the other hand, the exhaust gas discharged through the conventional kiln device contains various harmful pollutants, and the various pollutants contained in the exhaust gas are scattered in the air, thereby causing a lot of harmful effects on human health. It was.

상기와 같은 문제점을 해결하기 위한 본 발명의 첫째목적은 탄화용 제1 킬른로와 가스활성화용 제2 킬른로에 공급되는 연소열이 각 킬른로의 양쪽 끝단에서 동시에 공급되는 구조를 제공하여 최단시간에 각 킬른로의 내부온도가 일정하게 유지되게 하는 예열공정을 감소시킴으로써 생산성 향상과 고품질의 활성탄을 제조할 수 있는 연속식 활성탄 제조장치를 구현하는 데 있는 것이다.
The first object of the present invention for solving the above problems is to provide a structure in which the combustion heat supplied to the first kiln for carbonization and the second kiln for gas activation is simultaneously supplied from both ends of each kiln furnace in the shortest time. It is to implement a continuous activated carbon production apparatus that can improve productivity and produce high quality activated carbon by reducing the preheating process to keep the internal temperature of each kiln constant.

그리고 본 발명의 다른 목적은 탄화용 제1 킬른로와 가스활성화용 제2 킬른로에 공급된 연소열이 각 킬른로의 내부를 순환하는 구조를 제공하여 연소가스의 소비를 최소로 억제할 수 있게 함으로써 연료비를 절감할 수 있는 연속식 활성탄 제조장치를 구현하는 데 있는 것이다.
Another object of the present invention is to provide a structure in which the heat of combustion supplied to the first kiln for carbonization and the second kiln for gas activation circulates inside each kiln, thereby minimizing the consumption of combustion gas. It is to implement a continuous activated carbon production apparatus that can reduce fuel costs.

본 발명의 또 다른 목적은 폐열회수부에 배기가스 응집구조를 제공하여 외부로 배출되는 배출가스의 비산을 최소로 억제할 수 있는 연속식 활성탄 제조장치를 구현하는 데 있는 것이다.Still another object of the present invention is to provide a continuous activated carbon production apparatus capable of minimizing the scattering of exhaust gases discharged to the outside by providing an exhaust gas aggregation structure in the waste heat recovery unit.

상기와 같은 목적을 달성하기 위한 수단을 보다 상세하게 설명하고자 한다.
It will be described in more detail the means for achieving the above object.

다음으로 본원 발명의 연소가스에 포함되어 있는 폐열 회수구조는 도 3에 도시한 바와 같이, 탄화용 제1 킬른로(200)의 내부 공간부(260)에서 상기 유기물 원료(110)가 가열되어 탄소결정체의 탄화물(280)으로 생성될 때, 상기 유기물 원료(110)에 함유되어 있는 불순물이 연소되는 과정에서 발생되는 배기가스는 제1 틀체(210)의 양쪽 끝단으로 형성시킨 탄화물 토출구(250) 및 이송관체(240)를 경유하여 제2 틀체(310)의 내부 공간부(360) 및 폐열회수부(400)를 구성하고 있는 배기가스 수집관(420)으로 유입되어 배기가스 응집관(440)을 통하여 외부로 배출되어 진다.
Next, in the waste heat recovery structure included in the combustion gas of the present invention, as shown in FIG. 3, the organic material raw material 110 is heated in the internal space 260 of the first kiln furnace 200 for carbonization and thus carbon.
