Description
本發明係有關於一種將鋁渣、鋁集塵灰轉變為建材原料粉體的製作方法，主要係將回收廢棄物之未處理鋁渣、鋁集塵灰製成再生之建材原料粉體，該建材原料粉體可應用於燒結成磁磚，達到磁磚不會膨脹破裂。The present invention relates to a method for converting aluminum slag and aluminum dust ash into building material raw material powder, mainly to convert untreated aluminum slag and aluminum dust ash of recycled waste into recycled building material raw material powder. The building material raw material powder can be used for sintering into ceramic tiles to achieve the goal that the ceramic tiles will not expand and crack.
目前在全球循環經濟與節能減碳的氛圍下，再生鋁取代原生鋁是鋁工業欲達成零碳排目標的積極做法，當進口鋁錠或回收鋁材進行二次煉鋁，會利用一高溫爐將原料鋁熔成金屬熔湯，並添加還原劑、助熔劑及其他助劑去抓取原料鋁中的雜質，此時雜質及鹽類多浮於金屬熔湯表面，形成浮渣層，可隔絕空氣使金屬熔湯減少氧化，此浮渣層經定期耙除或傾倒，冷卻後之混合廢棄物即為鋁渣（Aluminum Dross, AD），而高溫爐之煙道集塵系統亦會有鋁集塵灰之排出，鋁渣（AD）可分為鋁含量高的塊狀原鋁渣 (Primary Aluminum Dross, PAD)及鋁含量低的顆粒狀二次鋁渣 (Secondary Aluminum Dross, SAD)，鋁渣（AD）除了含有雜質與少量金屬鋁，尚有氧化鋁(Al 2O 3)，也容易與氮氣形成氮化鋁(AlN)，若將其存放在有水氣的環境下，則容易反應產生氨氣而有刺鼻臭味，具有惡臭、化性不穩定、具燃燒性等不易處理特性，因此隨意堆置會造成環境問題，而回收處理業者主要以掩埋方式為主，然而，掩埋方式仍會嚴重污染大氣、土壤和水，引發諸多安全隱憂，破壞生態環境平衡，在先進國家中已逐漸被禁止。 At present, in the atmosphere of global circular economy and energy conservation and carbon reduction, the aluminum industry is actively taking the alternative of virgin aluminum to achieve the goal of zero carbon emissions by using recycled aluminum. When imported aluminum ingots or recycled aluminum materials are subjected to secondary aluminum smelting, a high-temperature furnace is used to melt the raw aluminum into a molten metal, and reducing agents, fluxing agents and other additives are added to capture impurities in the raw aluminum. At this time, impurities and salts mostly float on the surface of the molten metal to form a slag layer, which can isolate the air and reduce oxidation of the molten metal. This slag layer is regularly raked or dumped, and the mixed waste after cooling is aluminum slag (Aluminum Dross, Aluminum slag (AD) is a kind of aluminum slag that is produced by the flue dust collection system of the high-temperature furnace. Aluminum slag (AD) can be divided into primary aluminum slag (PAD) with high aluminum content and granular secondary aluminum slag (SAD) with low aluminum content. In addition to impurities and a small amount of metallic aluminum, aluminum slag (AD) also contains aluminum oxide (Al 2 O 3 ), and is also easy to react with nitrogen to form aluminum nitride (AlN). If it is stored in a water-filled environment, it is easy to react to produce ammonia with a pungent odor. It has bad odor, chemical instability, flammability and other difficult-to-handle characteristics. Therefore, random stacking will cause environmental problems, and recycling companies mainly use landfill as the main method. However, landfill will still seriously pollute the atmosphere, soil and water, cause many safety concerns, and destroy the balance of the ecological environment. It has been gradually banned in advanced countries.
一般將鋁渣、鋁集塵灰轉變為建材原料粉體的製作方法，請參閱第一圖所示，包含：將回收廢棄物之未處理鋁渣、鋁集塵灰混和；加入重量為粉體總重1%之黏結劑及粉體總重30%之水；進行混和攪拌十分鐘；取出放置整粒機成型，該整粒機篩網為4目；出料後投入旋轉窯爐鍛燒，該旋轉窯爐溫度為三區段，其中第一區段溫度500℃〜600℃，第二區段溫度1000℃〜1200℃，第三區段溫度1000℃〜1200℃，並調整該旋轉窯爐轉速與傾斜角，通過該旋轉窯爐時間為30分鐘；出料後形成未安定化鋁渣、鋁集塵灰顆粒團；再將該未安定化鋁渣、鋁集塵灰顆粒團研磨到200目以下，製成再生之建材原料粉體，並測得氮含量為3.7%；加入磁磚原料混和摻配百分比2%，並進行成形於溫度1230℃燒結，即可製成磁磚，但是此種磁磚容易膨脹破裂，可由該未處理鋁渣、鋁集塵灰結晶相分析圖得知，請參閱第二圖所示，該未處理鋁渣、鋁集塵灰中主要含有金屬鋁，另外均有一定含量之氮化鋁、尖晶石、氧化鋁及石墨，在空氣環境經過高溫燒結過程時，由於該氮化鋁會氧化形成氧化鋁，這個時候的晶相轉變會造成體積膨脹，因此若要應用於磁磚，必須妥適的將該氮化鋁氧化，透過X射線螢光分析儀(XRF)分析其氮含量可以間接確認該氮化鋁的含量，所以氮含量過高的鋁渣、鋁集塵灰摻配到磁磚中，進行燒結後會因為膨脹而造成磁磚的破裂。The general method of converting aluminum slag and aluminum dust ash into raw material powder for building materials is shown in the first figure, which includes: mixing untreated aluminum slag and aluminum dust ash from recycled waste; adding a binder with a weight of 1% of the total weight of the powder and water with a weight of 30% of the total weight of the powder; mixing and stirring for ten minutes; taking out and placing in a granulator with a 4-mesh screen for shaping; after discharging, putting into a rotary kiln for calcining, and the rotary kiln temperature is divided into three sections, of which the first section is The temperature of the first section is 500℃～600℃, the temperature of the second section is 1000℃～1200℃, and the temperature of the third section is 1000℃～1200℃. The rotation speed and tilt angle of the rotary kiln are adjusted. The time of passing through the rotary kiln is 30 minutes. After the material is discharged, unstabilized aluminum slag and aluminum dust ash granules are formed. The unstabilized aluminum slag and aluminum dust ash granules are then ground to less than 200 meshes to make recycled building material raw material powder, and the test is carried out. The nitrogen content is 3.7%; add the raw material of the ceramic tile and mix it with the percentage of 2%, and then form it and sinter it at a temperature of 1230℃ to make ceramic tiles. However, this kind of ceramic tile is easy to expand and rupture. It can be seen from the crystal phase analysis diagram of the untreated aluminum slag and aluminum dust ash. Please refer to the second figure. The untreated aluminum slag and aluminum dust ash mainly contain metallic aluminum, and also contain a certain amount of aluminum nitride, spinel, aluminum oxide and graphite. In the air environment During the high-temperature sintering process, the aluminum nitride will oxidize to form aluminum oxide. The crystal phase transition at this time will cause volume expansion. Therefore, if it is to be used in tiles, the aluminum nitride must be properly oxidized. The nitrogen content can be indirectly confirmed by analyzing its nitrogen content with an X-ray fluorescence analyzer (XRF). Therefore, if aluminum slag or aluminum dust ash with excessive nitrogen content is mixed into the tiles, the tiles will rupture due to expansion after sintering.
