Description

유기성 및 가연성 폐기물 종합처리 시스템{A processing plant for waste}A comprehensive processing system for organic and flammable waste

본 발명은 유기성 및 가연성 폐기물 종합처리 시스템에 관한 것으로서, 더욱 상세하게는 음식물 및 하수 슬러지 같은 유기성 폐기물을 건조하여 고형연료화 하되 가연성 폐기물을 혼합하여 고형화함으로써, 유기성 폐기물의 부족한 열량이 보충되어 연소기에서 완전 연소가 가능하게 되므로 미연소가스 및 유해가스의 발생이 줄어들고, 유기성 폐기물의 건조 과정에서 발생되는 증발 악취가스는 연소기에서 함께 연소시키므로 대기를 오염시키지 않으며, 특히 음식물 쓰레기, 하수 슬러지 및 가연성 폐기물을 한 장소에서 처리할 수 있으므로 혐오시설의 장소가 줄어 입지확보에 유리한 유기성 및 가연성 폐기물 종합처리 시스템에 관한 것이다.The present invention relates to a comprehensive system for treating organic and combustible wastes, and more particularly, to dry organic wastes such as food and sewage sludge to solidify fuel mixtures, and to solidify by mixing the combustible wastes, so that insufficient heat amount of organic wastes is supplemented to complete the combustion in the combustor. Combustion is possible, which reduces the generation of unburned gas and harmful gas, and evaporative odor gas generated during the drying of organic waste is burned together in the combustor so that it does not pollute the air, especially food waste, sewage sludge and flammable waste. The present invention relates to a comprehensive system for treating organic and flammable wastes, which can be disposed of at a location, thereby reducing the location of the aversive facility.

음식물 및 하수 슬러지 같은 유기성 폐기물은 탈수 및 건조과정을 거치면서 고형연료화 하거나 또는 사료화되었다. 그러나 음식물 및 하수 슬러지를 각기 다른 장소에서 고형연료화 하거나 또는 사료화하였으므로 혐오시설의 설치장소가 분산되어 현지 주민들의 반대가 빈번하게 발생되어는 문제가 있었다.Organic wastes, such as food and sewage sludge, have been solidified or feed through dehydration and drying. However, since food and sewage sludge were solidified or fed at different places, there was a problem in that opposition of local residents frequently occurred due to the dispersal of the installation site of the hate facility.

또한 음식물 및 하수 슬러지는 건조를 통하여 처리되므로 고열량의 연소기가 필요한데, 이들 폐기물을 처리하여 고형연료화하더라도 열량이 3,500kcal/kg ∼ 3,700kcal/kg로 부족하여 보조 연료로 밖에 사용할 수 없으며, 이들 건조시설에서 발생되는 증발 악취가스는 대기를 오염시키므로 연소기에서 완전연소시켜야 되므로 고열 및 대용량의 연소기가 필요하게 되는 단점이 있었다.In addition, food and sewage sludge are processed through drying, so a high calorific combustor is required. Even if these wastes are treated to solid fuel, the calories are insufficient to be used as auxiliary fuel due to insufficient calories of 3,500 kcal / kg to 3,700 kcal / kg. Evaporative odor gas generated in the air polluting the atmosphere has to be completely burned in the combustor, there was a disadvantage in that a high-temperature and large-capacity combustor is required.

그리고 플라스틱 같은 가연성 폐기물 역시 상기 유기성 폐기물과는 별도의 장소에서 고형연료화되므로 혐오시설의 장소만 늘리게 되는 등의 문제가 있었다.In addition, combustible wastes such as plastics also have problems such as increasing the location of the aversive facility because the fuel is solidified in a separate place from the organic wastes.

본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 음식물 및 하수 슬러지 같은 유기성 폐기물을 건조하여 고형연료화 하되 가연성 폐기물을 혼합하여 고형화함으로써, 유기성 폐기물의 부족한 열량이 보충되어 연소기에서 완전 연소가 가능하게 되므로 미연소가스의 발생이 줄어들고, 유기성 폐기물의 건조 과정에서 형성되는 증발 악취가스는 연소기에서 함께 연소되어 대기를 오염시키지 않으며, 특히 음식물 쓰레기, 하수 슬러지 및 가연성 플라스틱 폐기물을 한 장소에서 처리하므로 혐오시설의 장소가 줄어 입지확보에 유리한 유기성 및 가연성 폐기물 종합처리 시스템을 제공함에 있다.The present invention was developed in view of the conventional problems, and an object of the present invention is to dry the organic waste such as food and sewage sludge to solidify by mixing the combustible waste to solidify, so that the insufficient heat amount of the organic waste is supplemented to complete in the combustor Combustion is possible, thus reducing the generation of unburned gases, and evaporative odorous gases formed during the drying of organic wastes are burned together in the combustor to not pollute the air, especially food waste, sewage sludge and flammable plastic waste in one place. The treatment reduces the location of the aversive facility, providing a comprehensive treatment system for organic and flammable waste, which is advantageous for securing the location.

본 발명은 음식물 쓰레기를 분쇄 및 선별하여 이물질이 제거된 음식물 쓰레기를 탈수기 및 건조기에서 탈수 및 건조하여 저장탱크에 저장하고, 하수슬러지를 1차 건조기에서 건조하여 분쇄기에서 분쇄한 뒤 2차 건조기에서 건조하여 저장탱크에 저장하며, 가연성 폐기물을 선별한 뒤 건조기 및 분쇄기에서 건조 및 분쇄하여 저장탱크에 저장하고, 상기 저장탱크 들의 음식물 건조제품, 하수슬러지 건조제품 및 가연성 폐기물 건조제품들을 하나의 혼합기로 투입하여 혼합하고, 압출 및 성형기에서 필요한 크기의 알갱이로 만들어 고형연료화 하며, 상기 고형연료를 연소기에서 연소시켜 스팀보일러를 가열시키고 이때 발생되는 열원으로 상기 탈수기 및 건조기들의 열원으로 사용하는 특징이 있다.The present invention crushes and sorts food waste, dehydrated and dried food waste from the dehydrator and dryer to store in a storage tank, dried sewage sludge in the primary dryer to grind in the crusher and dried in a secondary dryer And store in the storage tank, sorting combustible waste, drying and pulverizing in a dryer and grinder, and storing it in a storage tank, and putting food dried products, sewage sludge dried products and flammable waste dried products of the storage tanks into one mixer. By mixing, granulation to granules of the required size in the extrusion and molding machine to solidify the fuel, and to burn the solid fuel in the combustor to heat the steam boiler, characterized in that it is used as a heat source of the dehydrator and dryer as a heat source generated.

본 발명에 따르면 음식물 및 하수 슬러지 같은 유기성 폐기물을 건조하는 과정에서 발생되는 증발 악취 가스를 한곳으로 포집하여 하나의 연소기에서 완전연소시킬 수 있으므로 악취가스를 처리하는 설비를 줄일 수 있으며, 이들 유기성 폐기물의 부족한 열량을 가연성 폐기물로 보충할 수 있으므로 직접 연료화하여 유기성 폐기물의 건조에 필요한 열량을 공급할 수 있다.According to the present invention, since the evaporative odor gas generated during the drying of organic wastes such as food and sewage sludge can be collected in one place and completely burned in one combustor, it is possible to reduce the facilities for processing the odor gas, and Insufficient heat can be replenished with flammable waste, which can be directly fueled to provide the heat needed to dry organic waste.

그리고 종래에는 음식물 쓰레기와 하수 슬러지를 각기 다른 장소에서 증발 처리하였으나, 이를 한곳에서 처리할수 있으며 또한 가연성 폐기물 역시 같은 장소에서 고형연료화 하므로 설치장소의 개수가 줄어 입지선정에 유리하며, 민원의 소지가 그만큼 감소되는 특징을 갖는다. 또한 유기성 및 가연성 폐기물을 연계 처리하므로 유사 시설에 대하여 공동으로 사용하므로 설비비가 절감되고 유지 관리 및 인력이 감축되는 등의 효과가 있다.In the past, food waste and sewage sludge were evaporated in different places, but they can be treated in one place, and combustible waste is also solidified in the same place, so the number of installation sites is reduced, which is advantageous for site selection. Has a reduced feature. In addition, since organic and flammable wastes are linked to each other, similar facilities can be used jointly, thereby reducing equipment costs, maintenance and manpower.

도 1은 본 발명 한 실시예의 종합처리시스템의 블록도 로써, 본 발명 한 실시예의 시스템은 국내에서 발생되는 유기성 및 가연성폐기물을 처리하는 장치로써 수분을 함유한 유기성 폐기물 중 음식물류 폐기물(수분 87%이상) 및 하수슬러지(수분80%이상)를 분쇄/선별 및 탈수/건조하여 수분을 제거한 후, 고형연료화 하여 연소기의 연료로 사용할 수 있도록 하되, 부족한 열량을 가연성폐기물로 보충한 것이다.1 is a block diagram of a comprehensive treatment system according to an embodiment of the present invention, the system of an embodiment of the present invention is an apparatus for treating organic and flammable wastes generated in Korea. ) And sewage sludge (more than 80% of water) are pulverized / selected and dehydrated / dried to remove water, and then solidified to be used as fuel for the combustor, but insufficient heat is supplemented with combustible waste.

상기 가연성폐기물(각 가정에서 버리는 비닐류와 종이류 및 복합 플라스틱 포장재 등)은 선별/건조 및 분쇄하여, 유기성 폐기물의 건조제품과 혼합(음식물 건조물 20중량%이하, 하수슬러지 건조물 20중량%이하, 가연성폐기물 60중량%이상) 및 성형하여 고형연료를 제조한 후, 고형연료를 연소하여 연소시 발생되는 열원으로 음식물 및 하수슬러지 건조기 등의 건조 열원으로 재사용하는 장치이다.The flammable wastes (vinyls, papers and composite plastic packaging materials discarded in each household) are sorted / dried and pulverized and mixed with the dried products of the organic waste (20 wt% or less of food dry matter, 20 wt% or less of sewage sludge dry matter, flammable waste). 60% by weight or more) and molding to produce a solid fuel, the solid fuel is burned by the heat source generated during the combustion is a device for reuse as a dry heat source such as food and sewage sludge dryer.

음식물류 폐기물은 반입탱크(100)에 투입(수분 87%)되어 분쇄 및 이물질 선별기(101)에서 분쇄 및 선별하면 이물이 약 3%가 나오며 이물질(80%이상은 비닐류)은 가연성 폐기물의 이물질 선별기(301)로 이송하여 연계 처리한다. 음식물을 분쇄 후, 탈수기(102)에서 탈수과정을 거치면 탈수 케익(수분75%)은 건조기(103)로 이송하여 건조처리(수분 10%)되며, 음식물 투입량의 17%가 건조제품으로 나오며, 이는 건조제품 저장탱크(104)에 저장된다.Food waste is put into the input tank 100 (87% of water), and when pulverized and sorted in the crushing and foreign matter sorter 101, about 3% of foreign matter comes out, and foreign matter (more than 80% of vinyl) is a foreign matter sorter of flammable waste ( Transfer to step 301). After the food is crushed, the dehydration process in the dehydrator 102, the dehydration cake (water 75%) is transferred to the dryer 103 is dried (10% moisture), 17% of the food input comes out as a dry product, which The dry product storage tank 104 is stored.

이때 순수한 음식물류 폐기물 건조제품을 연소하면 발열량은 3,700kcal/kg가 발생되나 연료로 사용하기에는 발열량이 미흡함으로 가연성 폐기물의 혼합기(306)로 보내 혼합하여(가연성 폐기물의 20중량%이하) 고형연료화 하면 발열량이 높아지므로 연료로써 가치가 상승한다. 고형연료로 사용하고 남는 음식물 건조제품은 단미사료 및 유박비료의 재료로 사용한다. 처리과정 중 탈수기(102)에서 발생되는 탈 리여액 폐수와 건조기(103)에서 발생되는 응축폐수는 폐수처리장과 연계처리하고 건조기(103)에서 발생되는 비 응축 악취가스는 가연성 폐기물의 탈취연소로(310)에 흡입하여 처리한다.At this time, when calcined pure food waste dry product is burned, the calorific value is generated 3700 kcal / kg, but the calorific value is insufficient to be used as fuel. This increases the value as a fuel. Used as a solid fuel and leftover food dried products are used as ingredients for sweet foods and fertilizers. During the treatment process, the desorption filtrate wastewater generated in the dehydrator 102 and the condensate wastewater generated in the dryer 103 are treated in connection with the wastewater treatment plant, and the non-condensed malodorous gas generated in the dryer 103 is used as a deodorization combustion furnace of the combustible waste ( Inhalation 310).

하수슬러지는 반입탱크(200)에 투입(수분 80%이상)되어 1차 건조기(201)에서 건조하고(수분 60%), 고형연료 원료와 고화처리 설비로 분배되며, 고형연료의 원료로 사용하기 위하여는 1차 건조하여 분쇄기(202)를 거친 후, 2차 건조기(203)에서 함수율(수분 10%)을 감소시킨 뒤 건조제품 저장탱크(204)에 저장하며, 가연성 폐기물의 혼합기(306)에서 음식물 폐기물 및 가연성 폐기물과 혼합(가연성 폐기물의 15%)하여 고형연료의 원료로 사용한다.Sewage sludge is introduced into the loading tank 200 (more than 80% of water), dried in the primary dryer 201 (60% of water), distributed to solid fuel raw materials and solidification facilities, and used as raw materials for solid fuel. In order to dry it first, go through the crusher 202, reduce the moisture content (10% moisture) in the secondary dryer 203 and store it in the dry product storage tank 204, in the mixer 306 of combustible waste It is mixed with food waste and flammable waste (15% of flammable waste) and used as a raw material for solid fuel.

순수한 하수슬러지 건조제품을 연소하면 발열량은 3,500kcal/kg이 발생되나, 음식물류폐기물 건조제품과 마찬가지로 연료의 원료로 사용하기엔 발열량이 미흡함으로 가연성 폐기물과 혼합하여 고형연료화 하면 발열량이 높아지므로 연료로써 가치가 상승한다. 1차, 2차 건조기(201)(203)에서 발생되는 응축폐수는 폐수처리장과 연계처리하고 건조기에서 발생되는 비응축 악취는 가연성폐기물 공정의 탈취연소로(310)에 흡입하여 처리한다.When burning dry sewage sludge products, the calorific value is 3,500kcal / kg.However, like food waste dry products, the calorific value is insufficient to be used as a raw material of fuel. To rise. The condensed wastewater generated in the first and second dryers 201 and 203 is treated in conjunction with the wastewater treatment plant and the non-condensing odor generated in the dryer is sucked into the deodorizing combustion furnace 310 of the combustible waste process and treated.

하수슬럿지를 고형연료화 하지 않을 경우 1차 건조하여 혼합기(205)에 투입하고 혼화제로써 고화제(10%이하)를 혼합하여 성형기(206)에서 성형한 다음 양생기(207)를 거쳐 최종 제품이 생성된다. 생성된 하수슬러지 고화 제품은 매립 등의 복토제로써 활용한다.If the sewage sludge is not solidified, it is first dried and introduced into the mixer 205, mixed with a solidifying agent (10% or less) as a admixture, and then molded in the molding machine 206, and then the final product is produced through the curing machine 207. do. The produced sewage sludge solidification product is utilized as a covering agent such as landfill.

가연성폐기물은 생활폐기물 반입탱크(300)에 투입(수분 15%)되어 불연성이물 질(유리, 철재류등)을 이물질 선별기(301)에서 선별 제거하고 가연성 폐기물은 가연성 폐기물 선별기(302)에서 선별하여 이를 건조기(303)에서 건조하고 분쇄기(304)에서 1차 분쇄한 후 분쇄물 저장탱크(305)로 이송된다.Combustible waste is put into the domestic waste loading tank 300 (15% moisture) to remove non-combustible materials (glass, steel, etc.) in the foreign matter sorter 301, and combustible waste is sorted by the combustible waste sorter 302 It is dried in the dryer 303 and first pulverized in the crusher 304 and then transferred to the pulverized storage tank 305.

분쇄물 저장탱크(305)에서 배출된 가연성폐기물과(60% 이상)은 혼합기(306)로 투입되어 음식물 건조제품(20% 이하) 및 하수슬럿지 건조제품(20% 이하)과 혼합된 다음 압출 및 성형기(307)를 거쳐 고형연료화되어 저장탱크(308)에 저장된다. 저장된 고형연료는 연소기(309)에 투입되어 용융 및 분해를 거쳐 연소되며, 연소하며 발생된 열량(5000kcal/kg 이상)은 탈취 연소로(310)에서 완전연소된 뒤 스팀 보일러(311)로 전달되어 열원(스팀)을 생성한다. 생성된 열원은 음식물 건조기(103)와 하수슬러지 건조기 (201,203)및 가연성폐기물 건조기(303)의 간접 가열 열원으로 사용된다.Combustible waste discharged from the pulverized storage tank 305 (more than 60%) is introduced into the mixer 306, mixed with food dry products (20% or less) and sewage sludge dry products (20% or less), and then extruded and The fuel is solidified through the molding machine 307 and stored in the storage tank 308. The stored solid fuel is introduced into the combustor 309 to be burned through melting and decomposition, and the calories generated by burning are more than 5000 kcal / kg and completely burned in the deodorizing combustion furnace 310 and then transferred to the steam boiler 311. Create a heat source (steam). The generated heat source is used as an indirect heating heat source of the food dryer 103, the sewage sludge dryers 201, 203 and the combustible waste dryer 303.

상기 폐기물들은 우리의 일상생활에서 필연적으로 발생하는 것들로써 현재 각 폐기물들을 종류별로 처리하고 있으나 서로의 연관성을 갖지 않고 처리시설을 운영하였을 경우 2차 폐기물의 발생 및 운영비의 절감 효과가 없다.The wastes are inevitably generated in our daily lives, but currently each waste is treated by type, but when the waste treatment facilities are operated without any correlation, there is no effect of generating secondary waste and reducing operating costs.

본 발명은 상기 폐기물을 한 장소에서 연계처리하여 2차 폐기물 발생이 최소화되고 각 폐기물에 필요한 열에너지를 각 폐기물에서 추출하여 얻으므로 각 폐기물의 운전비를 현저하게 절감할 수 있다. 또한 국내 폐기물 처리시설의 입지 확보가 매우 어려운 점을 감안할 때, 세 가지 폐기물 처리시설을 한 장소에서 처리하므로 혐오시설에 대한 민원이 줄어들고, 가연성폐기물의 신생에너지 확보로 연료 수입의 대체효과가 있으며, 화석연료를 사용하지 않음으로 이산화탄소 배출을 억제하 여 대기오염 저감 시설로써도 효과가 크다.The present invention can reduce the operation cost of each waste because the waste is linked in one place to minimize the generation of secondary waste and to extract the heat energy required for each waste from each waste. In addition, considering that it is very difficult to secure the location of domestic waste treatment facilities, treating three waste treatment facilities in one place reduces civil complaints for aversion facilities and replaces fuel imports by securing new energy for combustible waste. By not using fossil fuels, CO2 emissions are also suppressed, making them effective as an air pollution reduction facility.
