Description
本發明是有關於一種安定化處理方法，特別是一種利用濕磨法進行安定化之轉爐石資源化處理方法。The invention relates to a stabilization treatment method, in particular to a converter stone resource treatment method which is stabilized by a wet grinding method.
查，轉爐石係為鋼鐵煉製後所產生之爐渣，而以往為有效使該等轉爐石爐渣成為資源化之產品，參閱圖1，其處理方式依序有堆料步驟11、篩選步驟12、破碎步驟13、磁選步驟14、分選步驟15及出料步驟16等；其中該堆料步驟11為使轉爐煉鋼後所產生之高溫液態爐渣降溫，其所使用之方法係將該等轉爐石渣傾倒於堆渣場地後進行噴水，以使該等轉爐石渣達到降溫、崩解及初步安定化等功效，而後再進行後續該等步驟，藉以確實將該等爐石有效資源化處理。Investigate that the converter stone system is the slag produced after the steel refining, and in the past, in order to effectively make the converter stone slag become a resource product, refer to Figure 1, the processing method has a stacking step 11, a screening step 12, The crushing step 13, the magnetic separation step 14, the sorting step 15 and the discharging step 16 and the like; wherein the stacking step 11 is to cool the high temperature liquid slag generated after the steelmaking of the converter, and the method used is the converter stone After the slag is poured into the slag yard, water is sprayed to achieve the effects of cooling, disintegration and initial stabilization of the converter slag, and then the subsequent steps are carried out to ensure that the whetstone is effectively resourced.
然，上述步驟之其前置處理作業，就於進行該等轉爐石渣進行降溫及完全安定化過程中，其安定化處理時間是非常冗長，不但無法有效控管安定化時間，且更需具備一面積較大場地堆放處理，以使產品資源化更不容易。However, in the pre-treatment operation of the above steps, during the cooling and complete stabilization of the converter slag, the stabilization treatment time is very lengthy, and it is not possible to effectively control the stabilization time of the tube, and it is more necessary to have A large area is stacked and processed to make product recycling easier.
有鑒於此，乃有進一步研究出一轉爐石快速安定化應於混泥土掺拌料之方法2，參閱圖2，其方法依序包含有備料步驟20、篩選步驟21、破碎磁選步驟22、分選步驟23、攪拌研磨步驟24、安定化步驟25及出料步驟26；其中，該備料步驟20、篩選步驟21及該破碎磁選步驟22係與前一習知製程相同，恕不詳述；然，該分選步驟23係將已破碎處理後依該等轉爐石粒徑大小，進而分選出適用之該等轉爐石後，即進入該攪拌研磨步驟24，且在進行該攪拌研磨步驟24過程中，係需添加一特定比例的安定化助劑，置入一具有攪磨機241反應槽內進行攪拌與安定化研磨，以使該轉爐石中所含之游離氧化鈣，係與研磨時產生之熱能及該安定化助劑反應安定化的碳酸鈣與蒸氣循環，而後在該安定化步驟25中係由一烘乾設備，將掺有該安定助劑且已研磨形成轉爐石粉，加以烘乾形成具安定化轉爐石粉末狀，最後依需求將該安定化轉爐石粉末取代爐石粉或直接運用於混凝土上(即該出料步驟26)，以提昇該轉爐石再利用之時效與功效，藉以創造產業利用上之實質經濟價值。In view of this, there is a further study of a method for rapid stabilization of a converter stone in a concrete mixed mixture. Referring to FIG. 2, the method includes a preparation step 20, a screening step 21, a fracture magnetic separation step 22, and a minute. Step 23, agitation grinding step 24, stabilization step 25, and discharge step 26; wherein the preparation step 20, the screening step 21, and the crushing magnetic separation step 22 are the same as the previous conventional process, and are not described in detail; The sorting step 23 is performed after the crushing treatment is performed according to the particle size of the converter stone, and then the suitable converter stone is sorted, and then the stirring grinding step 24 is entered, and during the stirring and grinding step 24 It is necessary to add a specific proportion of stabilizer to be placed in a reaction tank having a stirrer 241 for stirring and stabilization grinding so that the free calcium oxide contained in the converter stone is generated during grinding. The thermal energy and the stabilization aid react with the stabilized calcium carbonate and vapor cycle, and then in the stabilization step 25, a drying device is used, which is mixed with the stabilizer to form a converter stone powder and dried to form An The converter stone powder is powdered, and finally the stabilized converter stone powder is substituted for the whetstone powder or directly applied to the concrete (ie, the discharging step 26) according to the demand, so as to enhance the aging and effect of the converter stone recycling, thereby creating industrial utilization. The real economic value.
惟，在上述該攪磨機241反應槽內所添加之該安定助劑，其運用添加於資源利用上之成份須要有一定比例，且費用頗高，再者，欲利用攪磨機241要同時將該轉爐石同時完成攪拌、研磨成粉末狀，其技術是非常有限的，更何況於進行攪磨過程中，會造成部份該安定助劑無法附著於該等轉爐石上，且完成後更需多一道烘乾製程，才能使該轉爐石形成安定化轉爐石粉末狀，因此，不但無法使資源能有效再利用，更會浪費現有能源，使作業時間與製程增加外，更不符合節能減碳之經濟效益價值。However, in the above-mentioned stabilizer, the stabilizer added in the reaction tank of the agitator 241 needs to have a certain proportion of the components added to the resource utilization, and the cost is high, and further, the use of the agitator 241 is simultaneously required. The technology of the converter stone is stirred and ground into powder at the same time, and the technique is very limited, not to mention that some of the stabilizers cannot be attached to the converter stone during the agitation process, and further need to be completed after completion. Only one drying process can make the converter stone form a stable converter stone powder. Therefore, not only can the resources be reused effectively, but also the existing energy can be wasted, the operation time and process can be increased, and the energy saving and carbon reduction are not met. The value of economic benefits.

Then, the carbon dioxide (CO 2 ) gas is introduced into the gas device 323 to rapidly form an equilibrium reaction and stabilize the non-magnetic converter stone slurry. Further, the gas device 323 introduces carbon dioxide (CO). 2 ) The gas system can be reused by using the exhaust gas resources discharged during steelmaking, or by recycling the carbon dioxide (CO 2 ) gas generated and existing in the plant during operation, so as to achieve effective resource reuse.

由上述之說明，本發明確實具有以下所列之優點與功效：From the above description, the present invention does have the advantages and effects listed below:
1.本發明在進料製程中，無需等候該等轉爐石形成完全安定化後即可進行後續該等步驟，藉以有效控制作業場地使用，以提昇資源再利用之時效與功效。1. In the feeding process, the subsequent steps can be carried out without waiting for the formation of the converter stone to be completely stabilized, thereby effectively controlling the use of the work site, thereby improving the timeliness and efficacy of resource reuse.
2.本發明在安定化漿體步驟，其係利用一具濕磨功效之研磨裝置，即可直接立即針對未完全安定化之轉爐石進行粒徑縮小研磨，且於研磨製程中再藉該磁選設備，使進行研磨製程中得以一併進行磁選出非著磁性之轉爐石，同時在粒徑濕磨縮小形成漿體時，即能同步具有產生安定化反應作用，藉以有效縮短該等轉爐石漿體安定化之時效；再者，又可利用煉鋼時或工廠內所排放之廢氣資源，更加速該等非著磁性之轉爐石在進行濕磨處理過程中形成平衡反應及安定化作用，以使廢棄之資源得以再利用，進而成為有效之經濟價值產品，故確實有別於習知進行研磨、安定化添加製程之作業流程。2. The invention stabilizes the slurry step by using a grinding device with wet grinding effect, which can directly and directly reduce the particle size of the incompletely stabilized converter stone, and borrow the magnetic separation in the grinding process. The equipment enables the magnetic separation of the non-magnetic converter stone during the grinding process, and at the same time, when the particle size is wet-milled to form a slurry, the stabilization reaction can be simultaneously generated, thereby effectively shortening the converter stone slurry. The aging of the body is stabilized; in addition, the exhaust gas resources discharged during steelmaking or in the factory can be used to accelerate the formation of equilibrium reaction and stabilization during the wet grinding process of the non-magnetic converter stone. By recycling the discarded resources and becoming an effective economic value product, it is indeed different from the conventional process of grinding and stabilization.
3.本發明之另增設一集料步驟，俾將已形成轉爐石漿體利用該集收設備使轉爐石漿體得以進行安定化反應，再分批進行降低該等轉爐石漿體中水份以提昇轉爐石漿體之濃度，以使該等濃轉爐石漿體得以直接應用或添加於混凝土上，使作業成本得以有效降低，藉此不但能有效控制產品製程與品質，俾使能有效達到產業資源再利用與經濟價值提昇。3. An additional aggregate step of the present invention, wherein the converter stone slurry has been formed to utilize the collection device to stabilize the converter stone slurry, and then to reduce the moisture in the converter stone slurry in batches. In order to increase the concentration of the converter stone slurry, the concentrated converter stone slurry can be directly applied or added to the concrete, so that the operation cost can be effectively reduced, thereby not only effectively controlling the process and quality of the product, but also effectively achieving the product. Reuse of industrial resources and economic value.
歸納前述，本發明利用濕磨法進行安定化之轉爐石資源化處理方法，藉由進料步驟、安定化漿體步驟及出料步驟等一貫化之實施，得以有效促進轉爐石之資源再利用之功效，與提昇產業資源再利用之經濟與價值，故確實能達到本發明之目的。In summary, the present invention utilizes a wet grinding method to stabilize the converter stone resource treatment method, and is effective in promoting the reuse of the converter stone by consistently implementing the feeding step, the stabilization slurry step, and the discharging step. The effectiveness and the economic and value of industrial resource reuse can indeed achieve the purpose of the present invention.
