본 발명은 분말활성탄의 제조방법 및 제조장치에 관한 것으로, 더욱 상세하게는 폐기물로 취급하던 기존의 기초활성탄이나 미반응 카본을 사용하여 흡착력이 우수한 분말활성탄을 제조하게 되는 분말활성탄의 제조방법 및 제조장치에 관한 것이다.일반적으로, 석유화학공정에서는 석유화학제품의 기초원료를 생산하기 위하여 합성가스를 제조하게 되는데, 이 합성가스의 제조공정은 벙커시오일과 크루드오일(Crude-Oil)등을 산소와 스팀하에서 산화시켜 탄소, 일산화탄소, 수소, 일산화 탄소+수소 등의 제조과정을 거쳐 합성가스를 제조하게 된다.다시 말하면, 도 1a에 도시한 바와 같이 가스화반응기(1-3)에서 벙커시오일과 기타오일을 보일러(1-1)와 산소예열기(1-2)를 이용하여 부분산화시켜 합성가스(CO+H2)를 제조하게 되고, 1~2%의 기초활성탄(반활성 및 미반응상태)을 생성하게 된다.이때, 가스화반응기(1-3)에서 부분산화시 발생되는 열은 폐열교환기(1-4)에 서 40kg/㎤G의 고압스팀으로 회수하게 된다.또한, 가스화반응기에서 생성된 가스중의 검댕과 매연, 재는 억제탑(Quench Tower)(1-5)및 분리탑(1-6)을 거치면서 제거되고, 이처럼 억제탑과 분리탑을 거치면서 생성되는 기초활성탄은 압축여과기(1-7)에서 탈수되어 회수된다.그리고, 벙커시오일 및 기타오일이 연료로 사용되어 연소실(1-9)에서 연소될 경우 미반응 카본이 사이클론(1-10)과 집진기(1-11)를 거쳐 포집된다.한편, 상기와 같은 공정을 통해 발생되는 기초활성탄 및 미반응 카본은 지금까지 산업폐기물로 분류되어 소각 및 폐기물로 처분되면서 그 과다한 처리비용과 환경오염을 초래하는 등의 문제가 있었다.The present invention relates to a method for producing powdered activated carbon and a manufacturing apparatus, and more particularly, to a method for producing powdered activated carbon which produces powdered activated carbon having excellent adsorptive power by using existing basic activated carbon or unreacted carbon treated as waste. In general, in petrochemical processes, syngas is produced to produce basic raw materials for petrochemical products. The process for syngas production includes bunker oil and crude oil. Oxidized under oxygen and steam to produce a synthesis gas through the manufacturing process of carbon, carbon monoxide, hydrogen, carbon monoxide + hydrogen, etc. In other words, as shown in Figure 1a, bunker sea oil in the gasification reactor (1-3) And other oils are partially oxidized using a boiler (1-1) and an oxygen preheater (1-2) to produce syngas (CO + H 2 ), and 1 to 2% of basic activated carbon (semi-active and In this case, heat generated during partial oxidation in the gasification reactor (1-3) is recovered by the high pressure steam of 40kg / cm3G in the waste heat exchanger (1-4). Soot, soot and ash in the gas produced in the reactor are removed through the quench tower (1-5) and the separation tower (1-6), and thus the basic activated carbon produced through the suppression tower and the separation tower. Is dehydrated and recovered in a compressed filter (1-7). When bunker sea oil and other oils are used as fuels and burned in the combustion chamber (1-9), unreacted carbon is stored in a cyclone (1-10) and a dust collector ( On the other hand, basic activated carbon and unreacted carbon generated through the above process are classified as industrial wastes so far and disposed of as incineration and wastes, resulting in excessive processing cost and environmental pollution. There was a problem.

Basic activated carbon generated in the synthesis gas production process for producing the basic raw material or unreacted carbon generated during combustion is introduced into the first grinder 2-2 through the quantitative feeder 2-1. In the first mill (2-2), the unreacted carbon supplied from the metering unit (2-1) is crushed into 30 to 80 mesh, and the unreacted carbon is crushed to the conveyor belt (2-3). By using the raw material storage hopper (2-4) Then, the raw material storage hopper (2-4) is put into the kiln (2-8) by a predetermined amount. At this time, the kiln (2-8) is a rotary kiln (Rotary kiln) method, the inlet is high and the discharge port is low It is configured to easily control the movement of heat source by the suction fan and the heat residence time in the furnace. Here, the kiln 2-8 is operated at 600 to 800 ° C, and the basic activated carbon generated in the manufacturing process of syngas Is fired for 20 minutes at a temperature of 180 to 250 ° C, but when unreacted carbon in the fuel combustion process is used as a raw material, it is fired for 20 minutes at a temperature of 350 to 450 ° C. The raw material calcined in 2-8) is transferred to the second mill (2-9) and pulverized into fine powders of 195 to 205 mesh. However, in the first dust collector (2-13), the second mill in the kiln using a suction fan. A small amount of fine powder is sucked and stored in the fired raw material.

It is mixed and used as a filler of powdered activated carbon, which is stored in the secondary raw material storage hopper 2-12 as described above, and then put into the second mill 2-9 or through the inlet of the kiln 2-8. Here, the raw material collected in the second dust collector (2-10) is controlled by the moisture content of the moisture regulator (2-11) to the desired moisture content and shipped as powder activated carbon. By spraying water The moisture content of the powdered activated carbon is controlled by mixing water with the raw material. Meanwhile, when the powdered activated carbon produced by the above-described manufacturing apparatus and method is used for wastewater treatment, the method of use may vary depending on the characteristics and conditions of the wastewater. However, in general, it is preferable to dissolve it in water and use it. Particularly, as shown in FIG. 3, the method of using (a) to remove organic matter and chromaticity by adding powdered activated carbon to the water collecting plant 3-1 includes chemical oxygen demand. (COD), Biological Oxygen Demand (BOD), etc., are generally used when the chromaticity is weak, followed by precipitation for 3 hours or more with air and agitator, followed by other processes such as discharge and microbial treatment. The method of injecting powdered activated carbon at the position of b) requires chemical oxygen treatment by chemical treatment of wastewater in the sump (3-1) in a chemical treatment tank (3-2) and precipitation treatment in a precipitation tank (3-3). After removing the amount and chromaticity, the powder activated carbon is added, and after stirring for 3 hours or more in the microbial aeration tank (3-4), it is discharged to the settling tank (3-5). The method of use is the method of injecting powder activated carbon into the inlet of the microbial aeration tank (3-4), and the microbial growth, chemical oxygen demand, biological oxygen demand and color removal are carried out simultaneously. In addition, the method of adding powdered activated carbon at the position of (D) is based on the chemical oxygen demand and biochemical process based on the physical and chemical treatment, which is a pretreatment process. It is used when chemical oxygen demand, biochemical oxygen demand, and chromaticity remain due to substances such as oxygen demand and chromaticity that have been removed but not removed. As a method, it is the most preferable method of use, and powder activated carbon is introduced at the inlet of the secondary treatment tank and the settling tank (3-6), and then precipitated and discharged after stirring for 3 hours or more. Powdered activated carbon according to the invention is mixed with fertilizers (organic fertilizers or chemical fertilizers) and soil (4-1) in a rotary (4-2) and the like and used for planting and growth of plants, or first, powdered activated carbon and soil (4-1). ) Is used for planting and growing plants using mixed soil (4-3) mixed at the rotary, and fertilizer is added during the growth management. Plants grow well according to the absorption and release of nutrients. In addition, the powdered activated carbon of the present invention has an excellent adsorption capacity, and when it is continuously injected into the combustion gas during incineration of garbage, It is removed completely absorbed in the like.
