3. 발명 해결 방법의 요지3. Summary of Invention Solution
본 발명은 무기질의 산업폐기물, 슬럿지, 오니 및 유기성의 폐절삭유, 폐페인트, 폐유, 슬럿지등은 처리방법이 매우 난이하고 설혹, 처리한다해도 그 비용이 많이 들므로 메립이나 해양투기로 처리하는데 환경의 오염이 극심함을 해결하고 본 발명의 특징상 위의 폐기물들을 경량세라믹모래로 재활용된 제품과 정상적 원료로 제조된 제품을 비교하였을 때 전혀 손색이 없을 뿐 아니라 원가면에서 경쟁력이 있고 따라서 경제성이 있는 재활용제품을 생산하므로서 환경보전과 폐기물을 자원화하는 등의 여러부분에서 만족을 얻을 수 있게 한 것이다.In the present invention, inorganic industrial waste, sludge, sludge and organic waste cutting oil, waste paint, waste oil, sludge, etc. are very difficult to treat and are expensive even if they are treated. In order to solve the extreme pollution and to compare the above wastes with products recycled from lightweight ceramic sand and products made from normal raw materials, they are not only inferior but also competitive in cost and therefore economical.

Description
본 발명은 경량모래의 제조방법에 대한 것으로서 무기질이 함유된 각종 무기질 함유의 산업폐기물, 하수종말처리장, 폐수처리장에서 발생되는 슬럿지의 오니와 폐유슬럿지, 재활용할 수 없는 폐기물내에 있는 폐철강제, 폐목재, 폐프라스틱 등의 쇄석 되지 않고 덩어리로 된 것을 분류하여 빼버린 슬럿지와 다소의 점토, 적점토 같은 비용이 적게 드는 흙과 소량의 장석, 납석, 도석, 규석 등을 분쇄후 조합하여 미분쇄한 것으로 혼합하여 다용도 용의 경량모래를 제조할 수 있게 하여 국토나 해양의 환경오염을 제거하고자 하는 것이다.The present invention relates to a method for manufacturing light sand, industrial wastes containing various minerals containing minerals, sewage treatment plants, sludge sludges generated in wastewater treatment plants, waste oil sludges, waste steel steel in wastes that cannot be recycled, and wastes. It is a pulverized combination of crushed sludge, small clay, red clay, and small amounts of feldspar, feldspar, pottery stone, quartzite, etc. It is intended to remove environmental pollution of land or sea by making it possible to manufacture lightweight sand for multi-use by mixing.
지금까지 산업폐기물 또는 각종 슬럿지를 재활용하여 사용한 목적으로 개발한 것은 있으나 아직 사용할 수 있는 제품은 없었고, 특히 경량 모래로의 재활용은 없었다.Until now, there have been developments for the purpose of recycling industrial wastes or various sludges, but there are no products available yet, and in particular, there is no recycling to light sand.
산업폐기물이나 각종 슬럿지 재활용이 아닌 무기원료인 점토질류로 경량골재의 생산은 유럽지역의 몇 국가에서 생산하여 국내에까지 수출하고 있고 국내에서도 한 업체가 개발하여 생산을 하였으나 원가의 문제로 채산성이 없어 실패한 경우가 있고, 또한 국내에도 경량판넬 제조업체가 생산시설을 완성하여 유럽의 몇 국가에서 수입하여 생산하고 있으나 경량모래가 없어 패널의 경량화에 문제가 있다. 시장성은 국내 뿐만이 아니고 국제적 시장이 아주 다양하고 또한 시장의 규모가 매우 크다 할 수 있으며 보다 더 본 발명의 필요성은 산업 폐기물이나 각종 슬럿지의 재활용으로 환경오염의 문제가 해결되어야 할 절대적 과제인 것이다.The production of lightweight aggregate from clay wastes, which are inorganic raw materials, not industrial waste or various sludge recycling, is produced in several countries in Europe and exported to Korea, and developed by one company in Korea. In addition, in Korea, lightweight panel manufacturers have completed production facilities and imported and produced in several countries in Europe, but there is a problem in lightening the panel because there is no light sand. The marketability can be said that not only domestic but also international markets are very diverse and the size of the market is very large. Furthermore, the necessity of the present invention is an absolute problem that the problem of environmental pollution should be solved by recycling industrial waste or various sludges.
환경오염은 이제 매스컴을 통하지 않고서도 인간의 눈앞에 와 있는 현실이며, 따라 환경문제를 해결하지 못하면 인간의 대과오가 될 수 있는 점을 감안, 본 발명에 앞서 십여년 개발하여 여러건을 출원한 바 있는 초경량 발포세라믹의 원료복합무기화합물이 개발되어 있던 것을 토대로 폐기물슬럿지를 자원화하여 환경오염방지를 위하여, 수년전부터 연구개발 시험을 거쳐 본 발명으로 향후 최소한 무기질을 함유한 슬럿지는 95%이상 재활용할 수 있도록 한 것이다.Environmental pollution is now a reality that is in front of human eyes without going through the mass media, and if it does not solve the environmental problems, it can be a human error, so we have developed several decades prior to the present invention and applied for several cases. Based on the development of raw inorganic compound of ultra-light foamed ceramics, the waste sludge is recycled to prevent environmental pollution, and after several years of research and development, the present invention can recycle more than 95% of the sludge containing at least minerals. It would be.
본 발명을 공정별로 다음과 같이 설명한다.The present invention will be described as follows for each process.
[제1공정][Step 1]
원재료 폐기물을 분류에 있어 여러종류의 대부분 무기질이 함유된 산업폐기물, 슬럿지, 오니 등은 이미 미분쇄되어 있고 유기성의 폐유, 절삭유, 폐페인트 등은 액상으로 되어 있으나 폐기물인 만큼 그 속에 철, 프라스틱, 목재 등의 분쇄되어 있지 않고 덩어리로 되어 있는 것은 분류하여 제거하고, 불석, 장석, 규석, 도석, 납석, 백토, 적점토, 각종의 점토류를 로울러크락샤로 30mesh 이하로 미분쇄하여 RO(R2O)군의 염기성 산화물을 1로한 유식(제겔식)에 R2O3그룹의 중성산화물과 RO2그룹의 산성산화물군을 합성하여 조성식을 구한 다음 이러한 조성식을 이용하여 푼 조성비에 따라 추출 조합하여 건식방법으로 미분쇄 한다.In classifying raw materials waste, industrial wastes, sludges, sludges, etc. containing most kinds of minerals are already pulverized, and organic waste oils, cutting oils, waste paints, etc. are in liquid form, but they are iron, plastic, removed by classification it is a lump but not crushed, such as wood, and bulseok, feldspar, silica, pottery stone, pyrophyllite, clay, jeokjeomto, pulverized by RO (R 2 O with different types of clay flow below the roller keurak shallow 30mesh ) The composition formula is obtained by synthesizing the group of neutral oxides of R 2 O 3 group and the group of acid oxides of RO 2 group with the basic formula of basic oxide of 1) (Zegel's formula). Fine grinding
[제2공정][Step 2]
폐기물 슬럿지들과 복합무기화합물과의 혼합에 있어서 제3공정의 성형에 있어 다소의 수분이 함유되어 있어야 하는데 대부분의 폐기물 슬럿지들의 수분함유량이 매우 높아 수분을 첨가할 필요없이 폐슬럿지와 복합무기화합물을 일정한 비율로 투입 혼합한다.In the mixing of waste sludges with composite inorganic compounds, some moisture should be contained in the molding of the third process. Most of the waste sludges have a very high water content, so that waste sludges and composite inorganic compounds can be added without adding water. Input and mix at a constant rate.
[제3공정 성형공정][3rd process molding process]
성형방법은 주로 누덜머신으로 아주 작은 볼로 만들거나 강한 에어로 분사시켜 입자가 불규칙적이도록 하는 방법을 원칙으로 하고 필요용도에 의해 토련기를 이용 벽돌모양으로 크게 성형하거나 로울러 머신으로 아주 넓은 판상으로 성형하거나 프레스로 성형할 수가 있다.The molding method is mainly made of a small ball with a rag machine or sprayed with strong air to make the particles irregular.In principle, the molding machine can be used to form large bricks using a refining machine, or to form a large plate with a roller machine or press It can be molded.
[제4공정 건조 공정][4th process drying process]
성형공정에서 작은 볼로 형성된 입자나 불규칙적인 크고 작은 입자로 된 세라믹 모래용 성형물은 회전식 소성로의 예열대에서 건조가 이루어지므로 건조하지 않을 수도 있으나, 건조하는 것이 좋고, 특히 건조가 꼭 필요한 벽돌형이나 판상형처럼 크고 두껍게 된 성형물은 50℃∼300℃이내의 온도에서 12시간이상 잘운영 건조시킨다.In the molding process, moldings for ceramic sand formed of small balls or irregular large and small particles may not be dried because they are dried in a preheating zone of a rotary kiln, but it is preferable to dry them, especially brick or plate type that requires drying. The large and thickened moldings are dried well for more than 12 hours at a temperature of 50 ℃ to 300 ℃.
[제5공정 소성공정][5th baking process]
건조된 성형물을 소성로에 넣어 예열대에서 완전 건조 및 충분한 예열후 소성대에서 1,050℃∼1,300℃로 소성하는데 소성분위기는 산화염에서 중성염까지 되게 소성하게 되는데 세라믹 모래용 성형물은 회전식로에서 소성하고 벽돌형과 판상형은 터널로 또는 샤틀로, 마이크로로 등으로 소성할 수 있다.The dried moldings are put in a kiln and completely dried in a preheating zone and fired at 1,050 ℃ ~ 1,300 ℃ in the firing zone after the preheating stage. The minor component is fired from oxidized salt to neutral salt. The mold and plate can be fired in a tunnel furnace, a shaft furnace, a micro furnace, or the like.
[제6공정 냉각공정][6th cooling process]
세라믹모래제조에서의 회전식로내의 고온에서 별개의 냉각대를 통과하면서 크렉의 방지를 위해 서냉이 요구되고 벽돌형, 판상형의 크고 두꺼운 제품은 로내의 냉각대에서 아주 서냉시켜야 한다.Slow cooling is required to prevent cracking while passing through separate cooling zones at high temperatures in rotary furnaces in ceramic sand manufacturing, and large, thick brick- and plate-shaped products must be cooled very slowly in the furnace.
[제7공정 검사공정][7th process inspection process]
회전식 소성로에서 소성된 불규칙적 입자로 된 세라믹모래는 바로 출하할 수가 있으나, 벽돌형이나 판상형으로 크게 성형된 제품은 검사 분류하여 출하하고, 크렉이 생기거나 파손된 제품은 파쇄하여 모래의 용도로 이용할 수 있도록 하여 출하한다.Ceramic sands of irregular particles fired in rotary kilns can be shipped immediately, but products that are largely shaped into bricks or plates can be inspected and shipped, and cracked or broken products can be broken and used for sand. Should be shipped.
위와 같이 폐기물슬럿지를 재활용할 수 있는데, 폐기물 슬럿지의 경우 주로 매립이나 해양투기를 주로 고, 소각을 할려고 하나 소각시설의 비용이 엄청나게 드는 문제점이 있다. 재활용을 하게 되면 소각시설의 비용보다 적게 투자되며 또한 현재 요업계의 사용화로 폐기되다시피한 요업설비가 되어 있는 공장을 재가동 재활용하면 엄청난 이득이 따르고 환경오염방지로 국토나 해양의 오염을 방지할 수 있는 큰 이점이 있다.The waste sludge can be recycled as above, but the waste sludge is mainly used for landfilling or dumping at sea, and the incineration facility is extremely expensive. Recycling will invest less than the cost of incineration facilities, and restarting and recycling the factory, which has been discarded due to the current use of the ceramic industry, will bring enormous benefits and prevent pollution of the land or ocean by preventing environmental pollution. There is a big advantage to have.

건조된 성형물을 소성로에 넣어 1020℃∼1300℃로 내부의 온도 편차를 최대한 줄이고 산화염에서 중성염으로 소성시켰다.The dried moldings were put in a kiln to reduce the internal temperature deviation as much as possible from 1020 ° C to 1300 ° C and fired from oxidized to neutral salts.
공정(5)Process (5)
소성된 재활용제품을 로내에서 아주 서냉시켜 해체시켰다.The calcined recycled product was dismantled very slowly in the furnace.
공정(6)Process (6)
냉각된 재활용제품을 분류하고, 벽돌형 제품과 판상형 제품의 크렉이 생기거나 파손된 제품을 파쇄시켜 세라믹 모래 재활용품으로 출고할 수 있도록 했다.Cooled recycled products were sorted, and cracked or broken bricks and plated products were shredded so that they could be shipped as ceramic sand recycled products.
위와 같이 본 발명은 각종 폐기물 슬럿지를 재활용하므로 환경문제해결과 산업체들이 가장 해결하기 어려운 부분을 해결하여 주므로 산업활동이 매우 활성화 되어 국가 경제에 까지 큰 이득을 얻을 수 있게 하고 건축시장에서는 값이 저렴하고 경량인 세라믹모래의 공급으로 건축에서 경량으로 운반이 용이하고 시공비가 적게 들어 원가절감등으로 건축계의 활기를 찾을 수 있을 것으로 기대되어 매우 유익한 발명인 것이다.As described above, the present invention recycles various waste sludges, thereby solving environmental problems and solving the most difficult parts of the industry, so that industrial activities are very active, which can greatly benefit the national economy, and inexpensive in the construction market. It is a very advantageous invention because it is expected to be able to find the vitality of the building industry by reducing the cost because it is easy to transport from the construction to light weight, and the construction cost is low due to the supply of lightweight ceramic sand.
