焚化爐燃燒垃圾所產生之底渣，一般係採取掩埋處理。然而，底 渣重金屬含量低係被歸類為一般廢棄物，在先進國家及資源缺乏國 家’其再利用已經非常普及，甚至歐洲先進國家已經百分之百的利用。 曰本大部分採取底渣與飛灰混合後，以電漿熔融的方式進行熔融處 理’再進行再利用。但在石化能源高漲的今日，此做法並不經濟。 目前所採取的底渣處理的程序均為先貯存底渣後，再依序進行破 碎、磁選、風選、渦電流選、過篩分選，以得到所需要的產品。 習知係對已經過熟化之底渣進行資源化濕式處理，如第三圖所 示，首先，如步驟S30，篩分出已熟化底渣中所包含之大型物；之後， 如步驟S32，透過磁選分軸紐情包含之鐵金屬；讀如步驟 S34 ’將分離出鐵金屬之底渣進行筛分，以分選成細料與粗料；其中， 細料與粗料後續將各別經過不同處理。細料處理如步驟挪，細料經 ，水洗，藉由大量的清水_，所含之氯離子去除且清水洗務 後之瀝乾婦經料祕學狀储舰絲水 係成為級配料；之後，如步驟娜，水洗後之泥水，透過2分^ ίί會土成分，並不適合做為細婦，且其巾重金屬含量 ^ θ尚°粗料處理係為步驟S4〇至步驟S44 鐵金屬，最後，如步流分選以分離出粗料中所包含之非 再次進行細__^八料進行顆滅碎，細社步驟S34 料篩刀。此外’於_S3〇所料出之大型物，更 201113482 可經由磁選或人工分選分離出鐵金屬，其餘之大型物係屬於大型之未 燃物或是結塊之底渣。此外，台灣專利200531743係也揭示底渣再利 用處理方法包含水洗程序，焚化底渣資源化再利用處理過程係經過水 洗製程的步驟成為可利用之工程級配用料。另外，美國專利 4,737,356、5,890,663、5,992,776、5,308,368 與 5,906,321 等專利 亦揭示底渣資源化的製程方法，底渣係經過破碎、篩選、分離等過程， 製做成為可再次利用之資源。 然而’上述美國專利揭示之習知底潰資源化處理方法皆相當繁 靖’需使用較高昂設備，且消耗極大的設備能源，並且對於所分離出 之鐵及非鐵金屬需要增加龐大設備做後續的處理，相當不符節能減 碳、經濟效益與永續利用的原則。此外，上述所列之台灣專利及習知 底潰資源化濕式處理方法，將需使用大量的水進行清洗作業，將氣離 子由底渣的固相洗到水相，再排放到環境中，以產品生命週期分析 (LCA)而言，對於環境影響並沒有減低’不僅浪費水資源不符合環保要 求，且後續的污水處理及排放亦是相當棘手問題，甚至造成二次環境 汙染，在水資源缺乏的台灣並不經濟，且亦不符合永續利用的原則。 另外’上述底>查處理流程中係對已經過熟化之底渔進行資源化處理， 已熟化之底渣於熟化過程時會發生水合作用，底渣中的物質係將結 塊’將大大造成後續處理的不便利性。由於底渣經水合作用係使得其 包含之鐵金屬沽粘許多其它物質，經磁選後，這些鐵金屬由於外覆雜 質太多，處理上極為困難，因此，往往乏人問津難以再次利用，造成 二次環境汙染。有鑑於此’本發明係針對上述所列舉的缺點，提出以 乾式處理方式將底渣資源化再利用之一種焚化爐底渣資源化之乾式處 理方法》 【發明内容】 本發明之主要目的係在提供一種焚化爐底渣資源化之乾式處理方 法’其係於底渣熟化前先進行磁選，有效避免底渣因水合作用與所包 201113482 含之鐵類金屬大量與其他物質產生結塊。 本發明之另一目的係在提供一種焚化爐底渣資源化之乾式處理方 法’其係於磁選及已熟化後，優先進行乾式篩選，篩選出底渣中含量 佔50%或50%以上之可用之細粒料’其餘之粗粒料再持續進行後續資 源化製程處理作業，故可有效增進底渣處理的效率。 本發明之又一目的係在提供一種焚化爐底渣資源化之乾式處理方 法，其係為乾式處理製程，不需使用大量的水進行洗滌作業，故可大 幅節省水資源消耗，更能夠達到節能減碳、資源永續利用之目的。 為達到上述之目的，本發明提出之焚化爐底渣資源化之乾式處理 • 方法，其係將未發生水合作用及未經過熟化的底渣進行磁選，以分離 出底渣所包含之鐵類金屬；之後對底渣進行熟化，以穩定底渣包含之 物質的化性與物性；再來將已熟化之底渣進行乾式篩分，以分選底渣 為細粒料與粗粒料。將粗粒料進行風選，以分離其所包含之未燃物； 分離未燃物後之粗粒料以渦電流將其所包含的非鐵類金屬分離；粗粒 料經過渦電流分選分離非鐵類金屬後進入破碎程序；最後以乾式篩分 方式’將經過破碎程序之粗粒料分選為細粒料與中粒料，且細粒料與 中粒料將以穩定化藥劑穩定其所包含之重金屬物質，以做為無筋混凝 土、人行道步磚、消波塊、防波堤、瀝青混凝土、道路基底層之配料 • 使用》 以下藉由具體實施例配合所附的圖式詳加說明，當更容易瞭解本 發明之目的、技術内容、特點及其所達成之功效。 【實施方式】 本發明提出一種焚化爐底渣資源化之乾式處理方法，係將焚化爐 所燃燒後產生之底渣以乾式處理方式，製做出符合公共工程規範所規 定之可應用於建築工程的級配材料，以達到廢棄物資源再利用的目 的。以下則將以較佳實施例詳述本發明之技術特徵。 如第一圖所示，一般大眾垃圾經垃圾車彳〇收集後係運送至焚化爐 201113482 12進行焚化作業，焚化爐12係為一般都市垃圾焚化爐或一般事業廢 棄物焚化爐。焚化爐12係以攝氏85CTC以上燃燒垃圾。經過焚化作業 後將產生燃燒殘留物底渣14，底渣14係為重金屬含量低於國家標準 之一般廢棄物’再經過喷水或浸水冷卻後，底渣14之水份含量係為 15%〜50%，並將被放置於貯坑16堆放。 於貯坑16堆放之底渣14將進一步經由本發明之乾式處理方式製 做成可資源化再生利用之工程建材，以下將對於底渣14進行乾式處理 方式成為可利用建材的步驟做詳盡的說明。 第二圖為本發明底渣資源化乾式處理之流程圖，如圖所示，首先， 如步驟S10 ’將由垃圾焚化廠所運送來之含水量為15%〜50%，且未 發生水合作用及未經過熟化之底渣14以孔徑為15〜3〇公分之栅攔 篩，將底渣14中大型之未燃物、大顆粒結塊及其他大型物質篩分，並 且同時採人工方式’將底渣14中未能以柵攔篩篩分出之大型未燃物、 大顆粒結塊及大型物質人工棟選去除。 其後’如步驟S12 ’藉由懸吊式磁選機、磁鼓機或輸送帶旋轉磁 鼓對已經柵攔篩篩選後之底渣14進行磁選，以分離底渣14中含有之 鐵類金屬，且分離出之鐵類金屬繼續進行除渣作業，以去除鐵類金屬 所黏附之些許底渣14 » 之後’如步驟S14，將已分離出鐵類金屬之底渣14以及由鐵類金 屬上所除下之底渣14放置於底渣貯坑中進行熟化，以穩定底渣包含之 各種物質的化學性質與物理性質。 再來’如步驟S16 ’以定量進料方式輸送底逢14，並且藉由圓筒 篩、震動篩、平篩或斜篩對已熟化之底渣14進行乾式筛分，將底逢 14分選成粒徑小於4J5公厘，為工程直接可使用之級配料的細粒料， 以及大於4.75公厘之粗粒料。其中定量進料方式輸送係可以自動秤量 方式達成’或以控制進料機轉速，進料口大小或進料履帶、皮帶、輸 送帶轉速或格板高度定量進料，或者以設置進料斗的高度控制進料 量。另外’於底渣14進行處理之前，先行取樣進行毒性溶出試驗(丁ci_p) /01113482 分析，當底渔14重金屬含量在法規標準值邊緣時，如步驟S26，將經 過步驟S16筛分出之細粒料喷灑穩定化學藥劑，使細粒料所包含的重 物質礦物彳t不致於溶出危害環境。峰料經喷職定化學藥劑穩 定後，方成為細粒料成品堆放。接著，如步驟S18，已分選出的粗粒 料再進-步進行加工處理，藉由以上吸式或由下往上高風速吹送的風 選機IB筒風選機、滾请風選機等藉由風選的力量對粗粒料進行風 選，且經過魏分離H將大顆粒她之未織，例如紐、棉布、塑 膠等輕質材料由粗粒料中分離；未燃物將送回焚化爐再進行焚化。其 中在粗粒料進行闕之步猶，或者於粗粒料絲顯之步驟後，更 籲可對粗粒料進行磁選’时離粗粒射所包含之麵金屬，確保被分 選為粗粒料之底產14巾不再存有類金屬：且進行粗粒料磁選所使用 之設備係如同上述如步驟S12所述之該些裝置。 、接下來’如步驟S2G所示’將綠料送人㈣流分選機對粗粒 7進行渦·分選’贿離絲料所包含_鐵類金屬。其中渦電流 分選機可糾叫式或偏雄絲麵，利職電流原理使粗粒料中 之非鐵金屬彈出分離，且於渦電流分選機後，可採用敍金屬材質之分 選機、’使粗粒料中所包含之不繞鋼可經由钕金屬所製成之分選機分 離。並且可採取人工方式，將粗粒料中未能以满電流分選機分離之大 籲型非鐵類金屬以人工楝選方式去除。 :然後’如步驟S22，將經過渦電流分選分離出非鐵類金屬之粗粒 料以颚碎機、錐销、挺補、賴式壓補、雜油财碎機 軸破碎機進行破碎。 最後’如挪S24 ’對已破碎之姉L料進行乾式較，分選已破 碎粗粒料為細粒料與十粒料，細粒料之粒徑係小於4 75公厘與上述步 驟=16中所述之細粒料之粒徑相同，並可混合堆置；中粒料之粒徑係 為；I於4.75 A厘至25公厘之間；粒徑大於25公厘之粗粒料將再回至 步驟S22巾進行破碎，並再次經過步驟S24進行乾式时。此外，當 底渣14處理前所進行的毒性溶出試驗(TCLp>分析顯示底逢14重金属[ 7 201113482 含量在法規標準值邊緣時，經過步驟S241帛分出之細粒料與中粒料將 經過步驟S26，喷職定化學細叙峰料與巾粒料所包含的的重 金屬物質’使重金屬物質礦物化，不致於溶出危害環境。經喷灑穩定 化學藥劑穩定後之細粒料與中轉，方成為細粒料成品與中粒料成品 分別堆放，並且步驟S24與步驟S16 !ί分ώ之細粒料成品_定化後 係為共同堆放。經由上述實施例說明可知本發明係為將經焚化爐彳2燃 燒後產生之底渣14 ’峨歧理方式’製做成可顧於絲混凝土、 磚品及土建材料之級配料的細粒料與中粒料，使底渣14能夠資源化再 利用於建築工程。且由於本案係為乾式處理，製程簡單不須如現今為 濕式製程運用大量的水進行洗滌，故可有效節省水資源，達到節能減 奴，且本案所述之方法係於底渣14進行熟化前優先進行磁選，可大大 避免底渣14與鐵金屬發生水合作用，且透過底渣14先行篩選分選成 細粒料及粗粒料，可増加50%以上的處理量，加速底渣14的處理效 能。，使其能夠做為無筋混凝土、碑品、道路、瀝青混凝土、控制性 低強度材料(CLSM)、溝管填料及土建材料之配料。 以上所述之實施例僅係為說明本發明之技術思想及特點，其目的 在使熟習此項技藝之人士能夠瞭解本發明之内容並據以實施，當不能 以之限定本發明之專利範圍’即大凡依本發明所揭示之精神所作之均 等變化或修飾，仍應涵蓋在本發明之專利範圍内。 【圖式簡單說明】 第一囷為本發明底渣產生之示意圖。 第二圖為本發明底渣資源化乾式處理之流程圖。 第三圖為習知底渣資源化濕式處理之流程圖。 【主要元件符號說明】 10垃圾車 12焚化爐 14底渣 16貯坑The bottom slag produced by the incinerator burning garbage is generally treated by landfill. However, the low level of heavy metal in the bottom slag is classified as general waste. In advanced countries and resource-poor countries, its reuse has become very popular, and even advanced European countries have already used it 100%. Most of the slag is mixed with fly ash and then melted by means of plasma melting and reused. But today, when petrochemical energy is rising, this is not economical. At present, the bottom slag treatment procedure is to first store the bottom slag, and then sequentially perform crushing, magnetic separation, air separation, eddy current selection, and sieve sorting to obtain the desired product. It is customary to carry out the resource-based wet treatment of the already-formed bottom slag. As shown in the third figure, first, in step S30, the large-sized material contained in the matured bottom slag is sieved; after that, as in step S32, Through the magnetic separation of the iron metal contained in the shaft; read the bottom slag of the separated iron metal according to step S34' to be sorted into fine and coarse materials; Different treatments. The fine material treatment is as follows: the fine material is washed, washed with water, and the chloride water contained in the water is removed by a large amount of water, and the water is washed and then drained. For example, Step Na, the muddy water after washing, through 2 points ^ ίί soil composition, is not suitable as a fine woman, and its towel heavy metal content ^ θ still ° rough material processing is step S4 〇 to step S44 iron metal, finally For example, the flow separation is performed to separate the non-repeated materials contained in the coarse material, and the fine particles are crushed, and the sieve is processed in the step S34. In addition, the large objects produced by _S3〇, 201113482 can be separated by magnetic separation or manual sorting. The other large items belong to large unburned materials or agglomerated bottom slag. In addition, Taiwan Patent No. 200531743 also discloses that the bottom slag reuse treatment method includes a water washing process, and the incineration bottom slag resource recycling treatment process is a step of a water washing process to become an engineering graded material. In addition, U.S. Patent Nos. 4,737,356, 5,890,663, 5,992,776, 5,308,368 and 5,906,321 also disclose a process for the recycling of bottom slag. The bottom slag is subjected to processes such as crushing, screening, separation, etc., and is made a resource that can be reused. However, the above-mentioned U.S. patents disclose that the underlying resource treatment methods are quite versatile, requiring high equipment and high energy consumption, and the need for adding large equipment for the separated iron and non-ferrous metals. The treatment is quite inconsistent with the principles of energy conservation, carbon reduction, economic efficiency and sustainable use. In addition, the above listed Taiwan patents and the known bottom-depletion resource-based wet processing method will require a large amount of water for cleaning operations, and the gas ions will be washed from the solid phase of the bottom slag to the aqueous phase and then discharged into the environment. In terms of product life cycle analysis (LCA), the environmental impact has not been reduced. 'Not only waste of water resources does not meet environmental protection requirements, but subsequent sewage treatment and emissions are also very difficult problems, and even cause secondary environmental pollution. The lack of Taiwan is not economical and does not meet the principle of sustainable use. In addition, the 'bottom bottom> check process is to recycle the already matured bottom fish, and the matured bottom slag will undergo hydration during the ripening process, and the material in the bottom slag will agglomerate. The inconvenience of subsequent processing. Since the bottom slag is made of ferrous metal, the iron metal contained therein is sticky with many other substances. After magnetic separation, these iron metals are extremely difficult to handle due to too much foreign matter. Therefore, it is often difficult to reuse them. Secondary environmental pollution. In view of the above-mentioned shortcomings of the present invention, a dry processing method for recycling an incinerator bottom slag using a dry treatment method for recycling the bottom slag is proposed. [ SUMMARY OF THE INVENTION The main object of the present invention is A dry treatment method for incinerating bottom slag resources is provided, which is magnetically selected before the bottom slag is matured, thereby effectively preventing the bottom slag from agglomerating due to hydration and a large amount of ferrous metals contained in the packaged 201113482. Another object of the present invention is to provide a dry treatment method for incinerator bottom slag resourceization, which is selected after magnetic separation and ripening, and preferably performs dry screening, and screens out the content of bottom slag which is 50% or more. The fine aggregates' remaining coarse aggregates are continuously subjected to subsequent recycling process, so that the efficiency of the bottom slag treatment can be effectively improved. Another object of the present invention is to provide a dry treatment method for incinerating bottom slag resources, which is a dry treatment process, which does not require a large amount of water for washing operations, thereby greatly saving water consumption and achieving energy saving. The purpose of reducing carbon and resources for sustainable use. In order to achieve the above object, the dry treatment method for incinerating bottom slag of the incinerator according to the present invention is to magnetically select bottom slag which has not undergone hydration and is not matured to separate iron contained in the bottom slag. The metal is then aged to stabilize the bottom slag to stabilize the chemical properties and physical properties of the material contained in the bottom slag; and the matured bottom slag is further subjected to dry sieving to separate the bottom slag into fine granules and coarse granules. The coarse aggregate is subjected to air separation to separate the unburned material contained therein; the coarse aggregate after separating the unburned material is separated by eddy current to separate the non-ferrous metal contained therein; the coarse aggregate is separated by eddy current separation After the non-ferrous metal, the crushing process is entered; finally, the coarse granules subjected to the crushing process are sorted into fine granules and medium granules by dry sieving, and the fine granules and the middle granules are stabilized by the stabilizing agent. The heavy metal materials contained are used as ingredients for unreinforced concrete, sidewalk bricks, wave blocks, breakwaters, asphalt concrete, and road base layers. • Use the following detailed description with specific examples in conjunction with the attached drawings. It is easier to understand the purpose, technical content, features, and effects achieved by the present invention. [Embodiment] The present invention provides a dry treatment method for incineration furnace bottom slag resource, which is to make the bottom slag generated after combustion of the incinerator in a dry treatment manner, and can be applied to a construction project in accordance with the provisions of public engineering regulations. The grading materials to achieve the purpose of recycling waste resources. The technical features of the present invention will be described in detail below with reference to preferred embodiments. As shown in the first figure, the general public garbage is collected by the garbage truck and transported to the incinerator 201113482 12 for incineration. The incinerator 12 is a general municipal waste incinerator or a general industrial waste incinerator. The incinerator 12 burns garbage at a temperature of 85 CTC or more. After the incineration operation, the combustion residue bottom slag 14 will be produced, and the bottom slag 14 is a general waste having a heavy metal content lower than the national standard. After the water spray or the water immersion cooling, the moisture content of the bottom slag 14 is 15%~ 50% will be placed in the storage pit 16 for stacking. The bottom slag 14 stacked in the storage pit 16 is further made into a recyclable engineering building material by the dry processing method of the present invention. The dry processing of the bottom slag 14 will be described as a step of using the building materials. . The second figure is a flow chart of the dry treatment of the bottom slag resource according to the present invention. As shown in the figure, first, as shown in step S10, the water content conveyed by the waste incineration plant is 15% to 50%, and no hydration occurs. And the untreated mature bottom slag 14 is screened by a grid having a pore diameter of 15 to 3 cm, and the large unburned material, large particle agglomerates and other large substances in the bottom slag 14 are sieved, and simultaneously artificially In the bottom slag 14, large unburnt materials, large particle agglomerates and large materials which have not been sieved by the grid screen are removed. Thereafter, as in step S12, the bottom slag 14 after screening has been screened by a suspension magnetic separator, a drum machine or a rotating drum of a conveyor belt to magnetically separate the ferrous metal contained in the bottom slag 14, And the separated ferrous metal continues to perform the slag removal operation to remove some of the bottom slag 14 to which the ferrous metal adheres. Then, as in step S14, the bottom slag 14 of the ferrous metal has been separated and the ferrous metal is removed. The bottom slag 14 is placed in a bottom sump for aging to stabilize the chemical and physical properties of the various materials contained in the bottom slag. Then, as in step S16, the bottom portion 14 is conveyed by the quantitative feeding method, and the matured bottom slag 14 is dry-screened by a cylindrical sieve, a vibrating sieve, a flat sieve or a diagonal sieve, and the bottom is divided by 14 The fine particle size is less than 4J5 mm, which is a fine-grained material of the grade which can be directly used for engineering, and the coarse-grained material of more than 4.75 mm. The quantitative feeding mode conveying system can be achieved by automatic weighing method 'or to control the feeding machine speed, the feeding port size or the feeding track, the belt, the conveyor belt speed or the grid height quantitative feeding, or to set the height of the feeding hopper Control the amount of feed. In addition, before the bottom slag 14 is treated, the sample is taken for toxic dissolution test (Ding ci_p) /01113482. When the 14 heavy metal content of the bottom fishing is at the edge of the regulatory standard value, as in step S26, the finely sifted through step S16. The granules spray stabilize the chemical, so that the heavy minerals contained in the fine granules are not dissolved and harm the environment. After the peak material is stabilized by spraying the chemical, it will be piled up as a fine material. Then, in step S18, the sorted coarse aggregates are further processed in a stepwise manner, and the air sorting machine IB cylinder air sorting machine, rolling air sorting machine, etc. are blown by the above suction type or from the bottom up and high wind speed. The coarse material is air-selected by the force of wind selection, and the large particles are unwoven by Wei separation. For example, light materials such as New Zealand, cotton, and plastic are separated from the coarse particles; unburned materials will be returned. The incinerator is incinerated. In the step of the coarse-grained material, or after the step of the coarse-grained material, it is more desirable to magnetically select the coarse-grained material when it is magnetically selected to ensure that it is sorted into coarse particles. The base material of the material is no longer stored with a metalloid: and the equipment used for magnetic separation of the coarse particles is as described above for the apparatus as described in step S12. Then, as shown in step S2G, the green material is sent to the (four) flow sorting machine for vortexing and sorting the coarse particles 7. The brittle wire contains ferrous metal. The eddy current sorting machine can correct or call the male silk surface, and the principle of profit current can make the non-ferrous metal in the coarse material pop out and separate, and after the eddy current sorting machine, the sorting machine of the metal material can be used. , 'The non-wound steel contained in the coarse aggregate can be separated by a sorting machine made of base metal. Moreover, the artificial non-ferrous metal which is not separated by the full current sorting machine in the coarse aggregate can be manually removed by manual selection. Then, as in step S22, the coarse particles of the non-ferrous metal separated by eddy current sorting are crushed by a crusher, a taper pin, a tapping, a Lai pressure, and a miscellaneous oil crusher. Finally, 'Ruo S24' is used to dry the crushed 姊L material, and the crushed coarse granules are fine granules and ten granules. The fine granules have a particle size of less than 4 75 mm and the above steps = 16 The fine granules described above have the same particle size and can be mixed and stacked; the particle size of the middle granules is; I is between 4.75 A and 25 mm; the coarse granules having a particle size of more than 25 mm will Then, the process returns to step S22 to perform the crushing, and the drying process is performed again through step S24. In addition, when the toxic dissolution test (TCLp> analysis performed before the bottom slag 14 treatment shows that the 14 heavy metals [ 7 201113482 content is at the edge of the regulatory standard value, the fine and medium granules separated by the step S241 will pass. Step S26, spraying the chemistry and clarifying the heavy metal materials contained in the peak material and the towel granules to mineralize the heavy metal materials, so as not to cause harm to the environment. The fine granules and the relay after the stable chemical agent is stabilized by spraying, The square is finished as a fine-grained product and a middle-grained product, and the fine-grained product of step S24 and step S16 is divided into a common stack, and the present invention is described as a The bottom slag 14 produced after the combustion of the incinerator 彳2 is made into fine and medium granules which can be used for the classification of silk concrete, brick and civil materials, so that the bottom slag 14 can be recycled. It is reused in construction engineering. Since the case is dry treatment, the process is simple, and it is not necessary to use a large amount of water for washing in the wet process, so it can effectively save water resources and achieve energy saving and slave reduction. The method is to perform magnetic separation preferentially before the bottom slag 14 is matured, which can greatly avoid the hydration of the bottom slag 14 and the iron metal, and the first slag 14 is firstly screened and sorted into fine granules and coarse granules, which can be added by more than 50%. The treatment capacity accelerates the treatment efficiency of the bottom slag 14, making it an ingredient for unreinforced concrete, monuments, roads, asphalt concrete, controlled low-strength materials (CLSM), trench pipe packing and civil construction materials. The embodiments are merely illustrative of the technical spirit and characteristics of the present invention, and the purpose of the present invention is to enable those skilled in the art to understand the contents of the present invention and to implement the invention. Equivalent changes or modifications made in accordance with the spirit of the present invention should still be included in the scope of the present invention.
