본 고안은 특히 활성탄의 재생 및 제조에 이용함에 적합한 통전식 가열로에 관한 것이다.The present invention relates in particular to electrically-heated furnaces suitable for use in the regeneration and production of activated carbon.
종래 활성탄은 각종액체 기체의 흡착성이 풍부하여 흡착제로 널리 사용하고 있고 특히 근년에는 상 하수 산업계수중의 오탁질을 제거해서 이들이 수직정화를 위해 다량으로 사용되고 있다. 한편, 대기오염, 악취공해 대책용의 흡착제로서의 사용량도 년년증가하고 있다.Conventional activated carbon is widely used as an adsorbent due to the rich adsorptivity of various liquid gases, and in particular, in recent years, it has been used in large quantities for vertical purification by removing the pollutants in the water supply and sewage industry. On the other hand, the amount of use as an adsorbent for air pollution and odor pollution measures is also increasing year by year.
통상 오탁성분을 흡착해서 활성이 저하된 활성탄은 재생부활해서 반복사용된다.Usually, activated carbon whose activity is lowered by adsorbing fouling components is regenerated and is used repeatedly.
활성탄의 재생부활은 900℃ 전후로 가열하고 다시 과열증기를 가해서 행하여 지며 이때의 장치로서 헬리쇼프형이라 불리는 다단붕식견형재생로나, 회전식횡형재생로가 사용되고 있다. 그러나, 이들은 기체 또는 액체연료의 연소열을 이용하고 있고, 그 설비비, 운전비의 코스트가 높다.The regeneration and regeneration of activated carbon is carried out by heating to around 900 ° C. and adding superheated steam again. As the apparatus at this time, a multi-stage roof dog regeneration furnace called a helischof type or a rotary horizontal regeneration furnace are used. However, they use the heat of combustion of gas or liquid fuel, and the cost of the equipment cost and the operation cost is high.
본 고안은 로 내벽에 설치된 전극간에 활성탄입자를 통과시켜 그 접촉저항과 고유저항에 의한 발열에 의해 활성탄을 가열 재생하는 것으로, 상기 활성탄의 품위수율도 높다.The present invention is to pass the activated carbon particles between the electrodes provided on the inner wall of the furnace to heat and regenerate the activated carbon by the heat generated by the contact resistance and the resistivity, the high yield of the activated carbon.
본 고안은 도면에 표시하는 한 실시예에 의해 상세히 설명하면, 상부로부터 공급조(1), 가열로(2), 부활로(3), 냉각조(4), 수조(5)로 구성되어 있고 수조(5)를 제외한 각부는 외경강판(6)의 플랜지(24)로 기밀조립식으로 되어 있고, 내벽에 각각의 용도에 맞는 내화단열재(7)를 사용하고, 공급조에는 레벨계(20)(21)를 부착하고 가열로와 부활로에는 각각 전극(8)과 (12), 그 상부에는 로내로부터의 발생가스를 유인하는 가스체임버(10)과 (14)가 있고, 다른 외부유인장치로부터 로외에 배출 처리된다. 또 전극(8)과 (12)에는 도전봉(9)와 (13)이 부착되어 있고, 외부전력공급장치로부터 소정의 전력이 공급된다. 전극 사이에 있는 열전대(11)과 (15)는 각로의 설정온도, 예를들면 가열로에서는 180℃, 부활로에서는 880℃로 유지되도록 온도조절계와 공급전력이 연동하고, 소정의 설정온도가 유지되도록 되어 있다.When the present invention is described in detail by one embodiment shown in the drawings, it consists of a supply tank (1), a heating furnace (2), an activation furnace (3), a cooling tank (4), a water tank (5) from the top, Each part except the water tank 5 is airtightly assembled by the flange 24 of the outer diameter steel plate 6, and the fireproof heat insulating material 7 suitable for each use is used for the inner wall, and the level gauge 20 (21) is used for a supply tank. Are attached to the heating furnace and the resurrection furnace, respectively, and there are electrodes 8 and 12, and gas chambers 10 and 14 for attracting the generated gas from the inside of the furnace, respectively. Discharge treatment. Conductive rods 9 and 13 are attached to electrodes 8 and 12, and predetermined electric power is supplied from an external power supply device. The thermocouples 11 and 15 between the electrodes are interlocked with the power supply so that the thermostat is maintained at a set temperature of each furnace, for example, 180 ° C. in the heating furnace and 880 ° C. in the regeneration furnace, and a predetermined set temperature is maintained. It is supposed to be.
부활로의 하부의 증기분출관(16)으로부터는 다른 장치로부터 보내지는 과열증기가 소정량분출된다.A predetermined amount of superheated steam sent from another apparatus is ejected from the steam jet pipe 16 at the lower part of the regeneration furnace.
냉각조는 처리능력이 작은 소형로에는 필요없으나 일반적으로는 수랭식스테인레스제 냉각기(17)를 두어 고온의 재생이 끝난 활성탄을 소정온도까지 내리고, 슈트(18)와 특수기어 및 전동기와 감속연동장치로 된 배출기(19)에 의해 수조(受槽)내에 낙하 배출된다.Cooling tanks are not required for small furnaces with low processing capacity, but generally have a water-cooled stainless steel cooler (17) to lower the high temperature regenerated activated carbon to a predetermined temperature. The discharger 19 is dropped and discharged into the water tank.
낙하배출된 재생이 끝난 활성탄량이 수조내의 레벨계(22)의 위치에 달하면, 밸브(23)가 자동적으로 일정시간 개방이 되어 재생이 끝난 활성탄을 수조밖의 소정의 장소로 보낼수가 있다.When the discharged regenerated activated carbon amount reaches the position of the level gauge 22 in the tank, the valve 23 automatically opens for a predetermined time, and the regenerated activated carbon can be sent to a predetermined place outside the tank.
배출기(19)로부터 재생이 끝난 활성탄이 연속적으로 배출됨으로서 로내의 활성탄은 중력에 의해 하측으로 이동하고 전류의 부분적인 통로를 만들지 않고, 즉 국부적으로 고온부분을 만들지 않고 재생온도의 균일화를 기할수가 있다.As the regenerated activated carbon is continuously discharged from the ejector 19, the activated carbon in the furnace moves downward by gravity and does not make a partial passage of electric current, that is, it is possible to uniformize the regeneration temperature without making a local high temperature part. have.
활성탄은 일반의 금속과 달라 고온이 될수록 전기저항치가 작아지고, 전류가 흐르기 쉽게 된다.Unlike activated metals, activated carbon has a high electric resistance, and thus an electric current easily flows.
공급조내의 활성탄은 중력 이동한 분량만큼씩 감소하고, 레벨계(21)의 하한 레벨이 되면 자동적으로 레벨계(20)의 상한 레벨이 될때까지 사용한 활성탄이 보급되고 연속적으로 자동으로 재생부활이 된다.The activated carbon in the supply tank decreases by the amount of gravity shifted, and when the lower limit level of the level gauge 21 is reached, the activated carbon is automatically supplied until the upper limit level of the level gauge 20 is reached and continuously regenerated and regenerated automatically.
본 고안에 의한 활성탄의 재생시험결과는 다음과 같다.Regeneration test results of activated carbon according to the present invention are as follows.

위 표에서 알수있는 바와같이 본 고안에 의한 종래의 비교예보다 활성탄의 회수율이 우수함을 알수있다.As can be seen from the above table, it can be seen that the recovery rate of activated carbon is superior to the conventional comparative example according to the present invention.
또, 이상에서 주로 활성탄의 재생의 경우를 설명하였으나, 본 고안의 로는 이런 경우만 아니라, 활성탄의 제조는 물론 다른 분말재료, 슬라지 등의 건조, 탄화 등에도 유효하게 사용할수가 있다. 또 본 고안은 가열로를 필요에 따라 임의의 단수만큼 쌓아 올린 다단으로해서 능력을 올릴수도 있는 것으로, 본 고안은 이럴때도 그 범위에 포함시키는 것으로 한다.In addition, although the case of regeneration of activated carbon is mainly described above, the furnace of the present invention can be effectively used not only in this case but also in the production of activated carbon, as well as in the drying and carbonization of other powder materials, slabs and the like. In addition, the present invention may increase the capacity by multi-stacking the furnace as needed in any number of stages, the present invention is also included in the scope even in this case.
