Description
本發明關於一種處理方法，特別是關於一種工業廢料處理方法。The present invention relates to a method of treatment, and more particularly to an industrial waste treatment method.
一般爐石多為作業鋼廠在煉鐵煉鋼過程中所產生的副產物，且因爐石中的殘鐵量高達可回收再利用之標準，故現今業者多選擇將爐石經處理後再利用於製作水泥原料，甚至作為道路工程或景觀園藝之建築材料。Generally, the hearthstone is mostly a by-product produced by the steel mill in the process of ironmaking and steelmaking, and because the amount of residual iron in the hearthstone is as high as the standard for recycling, the current industry has chosen to treat the hearthstone. Used in the production of cement raw materials, even as a building material for road engineering or landscape gardening.
傳統處理程序主要是將爐石經破碎、磁選、篩分而取得鐵粒或鐵砂等不同型態之著磁料。惟通過如此程序作爐石回收處理時，多因破碎後呈碎粒狀的各爐石塊所含鐵之成份不一，而容易在磁選過程忽略僅具弱磁性之爐石塊，甚至有部分殘鐵吸附於磁鐵上而不易被分離；因此，在爐石塊經傳統處理程序作磁選後其所含著磁料仍無法全面被回收，致使傳統回收效果確實有待進一步改良。The traditional processing procedure mainly involves crushing, magnetically selecting, and sieving the whetstone to obtain different types of magnetic materials such as iron or iron sand. However, when such a procedure is used for the recovery of the gangue, the components of the whetstones which are broken and granulated are often composed of different elements, and it is easy to ignore the only weakly magnetic furnace stones in the magnetic separation process, and even some of them. The residual iron is adsorbed on the magnet and is not easily separated; therefore, the magnetic material contained in the furnace stone block after magnetic separation by conventional processing cannot be completely recovered, so that the conventional recycling effect does need to be further improved.
此外，傳統回收方法仍舊會產生工業廢料。有鑑於此，確實有必要發展一種有別於傳統之工業廢料回收處理方法。In addition, traditional recycling methods still produce industrial waste. In view of this, it is indeed necessary to develop a method of recycling industrial waste that is different from the traditional one.

為讓本發明之上述及其他目的、特徵及優點能更明顯易懂，下文特舉本發明之較佳實施例，並配合所附圖式，作詳細說明如下：請先參考圖1，本發明實施例之工業廢料回收處理方法包含：破碎一工業廢料S1；磁選該破碎後工業廢料以得到一著磁料S2；水研磨該著磁料S3；及篩分該研磨後著磁料以得到一金屬粒料S4。The above and other objects, features and advantages of the present invention will become more <RTIgt; The industrial waste recycling treatment method of the embodiment comprises: crushing an industrial waste S1; magnetically selecting the crushed industrial waste to obtain a magnetic material S2; water grinding the magnetic material S3; and screening the ground magnetic material to obtain a Metal pellets S4.
為便於本領域具有通常者理解，本段先介紹用以實施本發明之設備示意圖。如圖2所示，設備主要包含破碎機1用以破碎工業廢料；磁選機2用以磁選該破碎後工業廢料以得到一著磁料；水研磨機3用以研磨該著磁料；篩分機4用以篩分該研磨後著磁料以得到一金屬粒料。破碎機1、磁選機2、水研磨機3、篩分機4之間分別以輸送帶5連接。磁選機2舉例如圖2所示具有一滾筒21及一載座 22，該滾筒21置於該載座22內，且該滾筒21內設有固定式磁鐵23，以使該滾筒21可環繞該固定式磁鐵23而轉動。水研磨機3內填充有研磨材31，研磨材31舉例可以是金屬球等具較佳硬度者。篩分機4舉例可以使用格柵篩等各式濾網。To facilitate the general understanding of the art, this section first introduces a schematic diagram of the apparatus for practicing the invention. As shown in FIG. 2, the apparatus mainly comprises a crusher 1 for crushing industrial waste; a magnetic separator 2 for magnetically selecting the crushed industrial waste to obtain a magnetic material; a water grinder 3 for grinding the magnetic material; and a screening machine 4 is used to sieve the ground magnetic material to obtain a metal pellet. The crusher 1, the magnetic separator 2, the water grinder 3, and the sifter 4 are connected by a conveyor belt 5, respectively. The magnetic separator 2 is exemplified as shown in FIG. 2 with a drum 21 and a carrier. 22, the drum 21 is placed in the carrier 22, and a fixed magnet 23 is disposed in the drum 21 so that the drum 21 can rotate around the fixed magnet 23. The water grinder 3 is filled with the abrasive material 31, and the abrasive material 31 may be, for example, a metal ball or the like having a preferable hardness. As the sieving machine 4, various types of sieves such as a grid sieve can be used.
請回頭參考圖1，本發明實施例中，破碎一工業廢料S1，其中該工業廢料可為來自煉鋼廠所產出的各種爐渣、爐石如高爐石或轉爐石等，或者該工業廢料可為各種飛灰、垃圾底渣、燃煤底渣、脫硫渣等各種工業廢料、泥灰渣工業廢料，或者各種含金屬之無機工業廢料。舉例來說，爐石中富含有大量殘鐵，即可選用為該工業廢料。該工業廢料較佳為無機工業廢料，特別是含金屬(可著磁)無機工業廢料。該工業廢料可為有價廢料或無價廢料。Referring back to FIG. 1 , in the embodiment of the present invention, an industrial waste S1 is crushed, wherein the industrial waste may be various slag, whetstone such as blast furnace stone or converter stone produced by a steel mill, or the industrial waste may be For various fly ash, garbage bottom slag, coal bottom slag, desulfurization slag and other industrial waste, sludge ash industrial waste, or various metal-containing inorganic industrial waste. For example, the hearthstone is rich in a large amount of residual iron, which can be selected as the industrial waste. The industrial waste is preferably inorganic industrial waste, especially metal-containing (magnetizable) inorganic industrial waste. The industrial waste can be valuable waste or priceless waste.
再者，破碎一工業廢料S1，其中破碎手段應可為本領域中具有通常知識者所理解，以能獲得粒徑大小符合實作所需為原則，不再贅述。舉例而言，可參考圖2，本實施例將爐石送入破碎機，將其破碎後，再經由不同網目之格柵篩作篩分，直至爐石被破碎至預定粒徑大小而得以經磁選出粒徑小的爐石塊為止，以優化後續磁選之效率。Furthermore, an industrial waste S1 is broken, wherein the crushing means should be understood by those having ordinary knowledge in the art, and the principle that the particle size is required to be practical is not described. For example, referring to FIG. 2, in this embodiment, the hearth is sent to a crusher, which is crushed, and then sieved through a grid of different meshes until the hearth is crushed to a predetermined particle size. Magnetic furnaces with a small particle size are magnetically selected to optimize the efficiency of subsequent magnetic separation.
磁選該破碎後工業廢料以得到一著磁料S2，舉例而言，可參考圖2實施例，遭破碎後工業廢料中具有磁性之碎塊稱為著磁料。著磁料例如具著磁性之鐵砂、鐵粉等鐵成份碎塊，可以為該固定式磁鐵23所吸引而附著於該滾筒21外壁，且隨該滾筒21轉動而在脫離磁性吸附後落於該輸送帶5上，以便後續程序將鐵砂、鐵粉等鐵成份加以回 收。磁選機2的配設並不以一台為限，亦可視實際情況所需，如本實施例之圖式連續配設有二台以上，且同樣以輸送帶5串連，藉以能更精確且全面性地回收工業廢料中的金屬成份。The crushed industrial waste is magnetically selected to obtain a magnetic material S2. For example, referring to the embodiment of Fig. 2, the magnetic fragments in the industrial waste after being broken are referred to as magnetic materials. The magnetic material, for example, a piece of iron composed of magnetic iron sand or iron powder, may be attracted to the fixed magnet 23 and attached to the outer wall of the drum 21, and may fall on the magnetic adsorption after the rotation of the drum 21 Conveyor belt 5 for subsequent procedures to return iron components such as iron sand and iron powder Received. The arrangement of the magnetic separator 2 is not limited to one, and may be required according to actual conditions. For example, the pattern of the embodiment is continuously provided with two or more, and the conveyor belt 5 is also connected in series, thereby being more precise and Comprehensive recovery of metal components from industrial waste.
請繼續參照圖1，磁選該破碎後工業廢料S2更可以得到一非著磁料。壓縮該非著磁料S5後可送至土資場作為填土材料等。例如，本實施例可以選擇利用造粒、打錠、壓縮等手段為之，以增進運送至土資場時之方便性。Please continue to refer to FIG. 1, magnetically selecting the crushed industrial waste S2 to obtain a non-magnetic material. After compressing the non-magnetic material S5, it can be sent to a land bank as a filling material. For example, in this embodiment, granulation, tableting, compression, and the like may be selected to improve the convenience of transportation to a land yard.
水研磨該著磁料S3，乃是將著磁料送入如圖2之內含研磨材31的水研磨機3內，且由於水研磨機3轉動過程持續注水於其中，使著磁料經該研磨材31撞擊且經水洗而除去其表面之非著磁性附著物。詳細地舉例，如圖2所示，以一注水管32自水研磨機3的入口端送入水，水可以是回用水。當水送入水研磨機3且隨該水研磨機3轉動時，借助其內部為研磨材31對著磁料作反覆撞擊，遂能加速整體研磨速度。同時，水研磨機3以水洗除去著磁料表面所沾附如泥、砂等附著物。The water is grinded by the magnetic material S3, and the magnetic material is fed into the water grinder 3 containing the abrasive material 31 as shown in FIG. 2, and the water is continuously injected into the water grinder 3 during the rotation process, so that the magnetic material passes through The abrasive material 31 collides and is washed with water to remove non-magnetic deposits on the surface thereof. As an example, as shown in Fig. 2, water is supplied from the inlet end of the water grinder 3 by a water injection pipe 32, and the water may be water. When the water is fed into the water grinder 3 and rotates with the water grinder 3, the inside of the material is rubbed against the magnetic material by the abrasive material 31, and the crucible can accelerate the overall polishing speed. At the same time, the water grinder 3 is washed with water to remove adhering substances such as mud and sand to the surface of the magnetic material.
篩分該研磨後著磁料以得到一金屬粒料S4，是指著磁料經水研磨S3後，再經過篩分機4以過濾得金屬粒料(如鐵粒料)及含金屬泥水(如含鐵尾料)。借此再經由如格柵篩等分離金屬粒料及含金屬泥水。之後，更可以磁選該含金屬泥水S7以得到一金屬砂料(如鐵砂、鐵精粉)。After sieving the ground magnetic material to obtain a metal pellet S4, the magnetic material is ground by water S3, and then passed through a sieving machine 4 to filter metal pellets (such as iron pellets) and metal muddy water (such as Iron-containing tailings). Thereby, the metal pellets and the metal-containing mud water are separated by, for example, a grid sieve. Thereafter, the metal-containing mud water S7 can be magnetically selected to obtain a metal sand material (such as iron sand or iron fine powder).
本發明較佳實施例之工業廢料回收處理方法中，另包含燒結該金屬粒料S6。因為燒結該金屬粒料後，燒結物中具有相當的金屬成分，例如鐵，後續便可送至煉鋼廠煉出 鋼材成品。此外，磁選該含金屬泥水S7後得到金屬砂料亦可以進行燒結，後續送至煉鋼廠煉出鋼材成品。In the industrial waste recycling processing method of the preferred embodiment of the present invention, the method further comprises sintering the metal pellet S6. After sintering the metal pellets, the sinter has a considerable metal composition, such as iron, which can be subsequently sent to the steel mill for refining. Finished steel products. In addition, the metal sand material obtained by magnetically selecting the metal mud water S7 can also be sintered, and then sent to the steel mill to refine the finished steel product.
磁選該含金屬泥水S7後可以得到廢水。沉澱S8或二次沉澱S9該廢水可以得到含金屬廢水汙泥及普通廢水汙泥。含金屬廢水汙泥如高鐵含量廢水汙泥(尾礦)，而普通廢水汙泥亦可含有少量金屬，例如低鐵含量廢水汙泥，可作為粒料燒結膠結劑。該含金屬廢水汙泥可送至水泥廠以混和水泥，或燒結該含金屬廢水汙泥以便送至煉鋼廠使用。該普通廢水汙泥亦可燒結以便送至煉鋼廠使用。The wastewater can be obtained by magnetically selecting the metal mud water S7. Precipitating S8 or secondary precipitation S9 can obtain metal-containing wastewater sludge and ordinary wastewater sludge. Metal-containing wastewater sludge such as high-iron content wastewater sludge (tailings), and ordinary wastewater sludge may also contain a small amount of metal, such as low-iron content wastewater sludge, which can be used as a pellet sintering binder. The metal-containing wastewater sludge can be sent to a cement plant to mix cement, or the metal-containing wastewater sludge can be sent to a steel mill for use. The ordinary wastewater sludge can also be sintered for use in a steel mill.
二次沉澱該廢水S9亦可以得到回用水，而回用水的用途很廣泛，例如水研磨該著磁料S3之步驟可以使用該回用水以水研磨該著磁料，或例如使用該回用水來水粹S10該工業廢料。The secondary precipitation of the wastewater S9 can also be used to obtain water reuse, and the reuse of water can be widely used. For example, the step of grinding the magnetic material S3 by water can use the recycled water to grind the magnetic material with water, or for example, using the recycled water. Water S10 this industrial waste.
如此一來，通過前述實施例步驟，便能自爐石被破碎後持續全回收其中如鐵粒、鐵砂、鐵粉等金屬成份，且過程中配合回用水的持續注入更可同時洗去沾附於該些金屬成份表面之泥、砂等附著物，以提升回收金屬之純度。In this way, through the steps of the foregoing embodiment, the metal components such as iron particles, iron sand, iron powder and the like can be continuously recovered after the furnace stone is crushed, and the continuous injection of the water back in the process can be washed away at the same time. Adhesives such as mud and sand on the surface of the metal components to enhance the purity of the recovered metal.
再者，本發明實施例提供了全回收的方法，例如將回用水持續地使用於水研磨機以節省新水的消耗與成本，或例如多次的磁選或多次的篩選，可以將目標金屬成分分離出來，且可以將目標成分以外的組成分加以循環利用，以強化全回收的效果。Furthermore, embodiments of the present invention provide a method of full recovery, such as continuously using recycled water in a water grinder to save new water consumption and cost, or, for example, multiple magnetic separation or multiple screening, the target metal can be used. The components are separated, and components other than the target component can be recycled to enhance the effect of total recovery.
關於全回收，例如將普通廢水汙泥(低鐵含量廢水汙泥)作為粒料燒結膠結劑之用，或將磁選過後的非著磁料送至土資場使用。Regarding the full recovery, for example, ordinary sewage sludge (low-iron content wastewater sludge) is used as a pellet sintering binder, or the magnetically selected non-magnetic material is sent to a land yard.
本發明實施例之工業廢料處理方法可以不斷的將目標物質(如鐵)粹選，且同時將其他組成分作出利用。換句話說，經由本發明實施例之工業廢料處理方法處理之工業廢料，可以不用再被廢棄，以達到全回收的目的。The industrial waste treatment method of the embodiment of the present invention can continuously select a target substance (such as iron) and at the same time utilize other components. In other words, the industrial waste processed by the industrial waste treatment method of the embodiment of the present invention can be discarded without being reused for the purpose of full recovery.
雖然本發明已利用上述較佳實施例揭示，然其並非用以限定本發明，任何熟習此技藝者在不脫離本發明之精神和範圍之內，相對上述實施例進行各種更動與修改仍屬本發明所保護之技術範疇，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention.
