More specifically, embodiments of the present invention relate to an exhaust gas treatment apparatus and an exhaust gas treatment method, which can suppress or prevent exhaust gas flow caused by differences between negative pressures in a plurality of processing zones of a processing system.

藉由使用細鐵礦石、石灰岩、焦炭、及無煙煤作為原材料來生產燒結礦石,然後將燒結礦石裝載至一鼓風爐中。在用於生產熔鐵之一鼓風爐製程中,將燒結礦石與鐵礦石及焦炭一起裝載至鼓風爐中。燒結礦石生產製程將細鐵礦石燒結成適合於鼓風爐使用之粒度。燒結礦石生產製程涉及製備原材料之混合物以及將混合物熱處理成燒結礦石。後者通常係在一燒結機中執行。 The sintered ore is produced by using fine iron ore, limestone, coke, and anthracite as raw materials, and the sintered ore is then loaded into a blast furnace. In a blast furnace process for producing molten iron, sintered ore is loaded into the blast furnace together with iron ore and coke. The sintered ore production process sinters fine iron ore to a particle size suitable for use in a blast furnace. The sintered ore production process involves preparing a mixture of raw materials and heat treating the mixture into sintered ore. The latter is usually performed in a sintering machine.

藉由對原材料之混合物進行熱處理來生產燒結礦石之製程係如下執行:在燒結運送車在燒結機之延伸方向上移動的同時,將原材料之混合物以一恆定高度裝載至該運送車上。藉由一點火單元(ignition unit)將原材料之混合物之一表面層點火,以形成一燃燒空窩(raceway)或燃燒區。使用一廢氣處理設備,將空氣強制性地向下輸入至燒結運送車中以使燃燒 空窩向下移動,藉此對原材料之混合物進行燒結,亦即,生產燒結礦石。然後,透過一壓碎機及一冷卻器將燒結礦石壓碎及冷卻,該壓碎機及該冷卻器設置於燒結機之一卸載區中。將被壓碎及冷卻之燒結礦石分類成適合於在鼓風爐中使用的5毫米(mm)至50毫米之顆粒,且然後將其轉移至鼓風爐。 The process of producing sintered ore by heat-treating the mixture of raw materials is performed as follows: while the sintering carriage is moved in the extension direction of the sintering machine, the mixture of raw materials is loaded onto the transportation truck at a constant height. One surface layer of the raw material mixture is ignited by an ignition unit to form a combustion raceway or combustion zone. Using an exhaust gas treatment device, the air is forcibly fed down into the sintering conveyor to burn it The cavity is moved down, thereby sintering the mixture of raw materials, that is, producing sintered ore. Then, the sintered ore is crushed and cooled by a crusher and a cooler, and the crusher and the cooler are arranged in an unloading area of the sintering machine. The crushed and cooled sintered ore is sorted into 5 millimeter (mm) to 50 millimeter particles suitable for use in a blast furnace, and then transferred to the blast furnace.

美國礦石業工程師協會(American Institute of Mining Engineers;AIME)的金賽(Kinsey)在1975年於美國公開一種用於改良燒結機之功能且進行節能之燒結廢氣循環技術。在此公開案中,提出一種具有如下結構之機上(on-strand)冷卻式燒結機:燒結機之一長度被延長,且為燒結機添加一冷卻器。此種構造包含一燒結區及一冷卻區。分別地自燒結區及冷卻區抽吸氣體。因此,藉由使自冷卻區排放之高溫廢氣作為熱空氣循環至燒結區中而提出一種節能型燒結模型。隨後,在20世紀70年代及80年代期間於日本及歐洲提出了類似研究或專利申請案。 American Institute of Mining Engineers Kinsey of Engineers (AIME) disclosed a sintering exhaust gas circulation technology for improving the function of sintering machines and saving energy in the United States in 1975. In this publication, an on-strand cooling sintering machine having a structure is proposed in which one of the sintering machines is extended in length and a cooler is added to the sintering machine. This structure includes a sintering zone and a cooling zone. Gas is drawn from the sintering zone and the cooling zone, respectively. Therefore, an energy-saving sintering model is proposed by circulating the high-temperature exhaust gas discharged from the cooling zone as hot air into the sintering zone. Subsequently, similar research or patent applications were filed in Japan and Europe during the 1970s and 1980s.

當對燒結機製程應用燒結廢氣循環技術時,可藉由將廢氣之顯熱(sensible heat)再循環用於燒結來減少燒結所需之能量。在第一次石油危機之後,於1984年在日本歌山縣(Wakayama in Japan),透過機上冷卻式燒結機對4號燒結(four-sintering)進行了改型,且然後,將燒結機之冷卻區段中之空氣再循環以重新用作燒結空氣。此外,在九州(Kyushu)及鹿島(Kashima),使用燒結廢氣循環技術來使廢氣自冷卻器循環至燒結機。於1991年在日本長野工業株式會社(NKK),為提高氣體抽吸容量並因此提高福山(Fukuyama)4號燒結之生產率,安裝一第二鼓風機,且使由第二鼓風機回收之廢氣朝向燒結機之一燒結礦石卸料單元再循環,藉此增強安裝於該燒結機中之一鍋爐的顯熱回收能力,同時提高氣體抽吸容量。 When the sintering exhaust gas circulation technology is applied to the sintering mechanism, the energy required for sintering can be reduced by recycling the sensible heat of the exhaust gas for sintering. After the first oil crisis, in 1984 in Wakayama in Japan, a four-sintering was modified by an on-board cooling sintering machine, and then the sintering machine was cooled The air in the section is recirculated for reuse as sintering air. In addition, in Kyushu and Kashima, sintering exhaust gas circulation technology is used to circulate exhaust gas from the cooler to the sintering machine. In 1991, in Japan's Nagano Industry Co., Ltd. (NKK), in order to increase the gas suction capacity and therefore the productivity of Fukuyama No. 4 sintering, a second blower was installed and the exhaust gas recovered by the second blower was directed toward the sintering machine A sintering ore discharge unit is recycled, thereby enhancing the sensible heat recovery capacity of a boiler installed in the sintering machine, while increasing the gas suction capacity.

上述方法旨在減少廢氣量,同時旨在藉由將廢氣之顯熱傳輸 至燒結層或點火爐而進行節能。為此,燒結廢氣循環技術被應用在燒結機製程。 The above method is aimed at reducing the amount of exhaust gas, and at the same time by transferring the sensible heat of the exhaust gas Save energy to the sintered layer or ignition furnace. For this reason, the sintering exhaust gas circulation technology is applied in the sintering mechanism.

同時,因環境政策法規之強制執行,用於處理硫氧化物(SOx)及氮氧化物(NOx)之處理系統之投資及運營成本現已造成負擔。 因此,每個國家的鋼廠都對溫室氣體法規作出回應,且在減少對污染預防系統之投資成本的同時藉由在最大程度上將來自燒結機之廢氣進行再循環來減少能耗。 At the same time, due to the enforcement of environmental policies and regulations, the investment and operating costs of processing systems for the treatment of sulfur oxides (SOx) and nitrogen oxides (NOx) are now burdened. As a result, steel mills in each country are responding to greenhouse gas regulations and reducing energy costs by recirculating exhaust gas from sintering machines to the greatest extent while reducing investment costs in pollution prevention systems.

舉例而言,新日鐵企業(NSC)的北九州(Kitakyushu)3號燒結於1992年藉由改良一燒結系統以在維持燒結礦石之生產率及品質的同時減少廢氣量而將廢氣量減少了28%。於1994年,德國魯奇公司(Lurgi,Germany)開發出一種排放最佳化燒結(Emission Optimized Sintering;EOS)技術並將其應用於荷蘭(Netherlands)的霍高文(Hoogovens)燒結廠,進而將廢氣量減少了約40%。此等案例能夠符合國際環境法規,但其技術尚未完成。 For example, Kitakyushu No. 3 sintered by Nippon Steel Corporation (NSC) reduced the amount of exhaust gas by 28% in 1992 by improving a sintering system to reduce the amount of exhaust gas while maintaining the productivity and quality of sintered ore. . In 1994, Lurgi (Germany) developed an Emission Optimized Sintering (EOS) technology and applied it to the Hoogovens sinter plant in the Netherlands. Reduced by about 40%. These cases can comply with international environmental regulations, but the technology has not been completed.

另外,自1994年以來,新日鐵企業的布津町(FUTSU)製程實驗室、奧地利的奧鋼聯集團(Voest-Alpine in Austria)、澳大利亞(Australia)的BHP以及意大利(Italy)的材料研究中心(Centro Sviluppo Materiali;CSM)一直致力於將燒結製程改造成一種環境友好型製程。住友商事公司(Sumitomo Corporation)正在研究一種雙級式(two-stage)點火燒結方法,其中在一機上冷卻式燒結機中,將原材料分別地裝載至上部級及下部級中,且將上部級及下部級中之材料點火並進行燒結,其中來自上部級之廢氣被重新用於對下部級中之材料進行燒結。 In addition, since 1994, the Nippon Steel Corporation's FUTSU process laboratory, Austria's Voest-Alpine in Austria, Australia's BHP, and Italy's Materials Research Center (Centro Sviluppo Materiali; CSM) has been committed to transforming the sintering process into an environmentally friendly process. Sumitomo Corporation is studying a two-stage ignition sintering method in which raw materials are separately loaded into an upper stage and a lower stage in an on-board cooling sintering machine, and the upper stage And the material in the lower stage is ignited and sintered, and the exhaust gas from the upper stage is reused to sinter the material in the lower stage.

為提高燒結礦石之生產率,存在一種增加廢氣處理設備中之 鼓風機容量以增加燒結空氣體積之方法、以及一種藉由擴大燒結機之焙燒面積來增加燒結空氣體積之方法。就此而言,當廢氣處理設備之鼓風機容量增加時,用於清潔廢氣之設施必須進一步延伸,且此外,廢氣處理設備之維護成本會增加。 In order to increase the productivity of sintered ore, there is an increase in A method of increasing the volume of the sintering air by the capacity of the blower, and a method of increasing the volume of the sintering air by expanding the firing area of the sintering machine. In this regard, as the blower capacity of the exhaust gas treatment equipment increases, facilities for cleaning the exhaust gas must be further extended, and in addition, the maintenance cost of the exhaust gas treatment equipment increases.

因此,浦項市的浦項鋼鐵(POSCO's Pohang)4號燒結已引入燒結廢氣循環技術。就此而言,為應對因鼓風爐內部容量之增加而引起的對燒結礦石之需求的日益增加以及高量排渣製程,燒結機之焙燒面積被擴展且因此燒結空氣流體積對應地增加。因此,為應對燒結空氣流體積增加,另一用於廢氣循環之鼓風機添加至為廢氣處理設備。 Therefore, POSCO's Pohang No. 4 sintering in Pohang has introduced sintering exhaust gas recycling technology. In this regard, in order to cope with the increasing demand for sintered ore due to the increase in the internal capacity of the blast furnace and the high-volume slag discharge process, the firing area of the sintering machine is expanded and the volume of the sintering air flow is correspondingly increased. Therefore, in order to cope with the increase in the volume of the sintering air flow, another blower for exhaust gas circulation is added to the exhaust gas treatment equipment.

就此而言,儘管將燒結層之通氣阻力最大的一位置定義為一廢氣抽吸位置,但所添加鼓風機在以上所定義之位置處使用一高壓力來吸取廢氣,並將廢氣朝向其中氧消耗相對較少的燒結層之一後端供應。由於被吸取至所添加鼓風機中之廢氣係朝向燒結層之一頂面循環,因而廢氣之總量可維持恆定。因此,甚至在浦項市4號燒結之焙燒面積增加並為其添加鼓風機時,亦可需要在廢氣處理設備中使用與廢氣清潔有關之現有結構,與廢氣處理設備未被改型時一樣。 In this regard, although the position where the ventilation resistance of the sintered layer is the largest is defined as an exhaust gas suction position, the added blower uses a high pressure to suck the exhaust gas at the position defined above, and directs the exhaust gas toward the relative consumption of oxygen. One of the fewer sintered layers is supplied at the back end. Since the exhaust gas sucked into the added blower circulates toward one of the sintered layers, the total amount of exhaust gas can be kept constant. Therefore, even when the firing area of No. 4 sintering in Pohang City is increased and a blower is added thereto, it is necessary to use the existing structure related to exhaust gas cleaning in the exhaust gas treatment equipment, as when the exhaust gas treatment equipment has not been modified.

舉例而言,當對一燒結礦石生產製程應用本發明之實施例時,氣體阻擋結構被設置於在運送車之行進方向上排列之該等風箱中與該 邊界相鄰之風箱之相鄰上部端上,而該等相鄰風箱界定之邊界介於廢氣循環區與廢氣排放區之間。當原材料被裝載於運送車上而該運送車在原材料被進行熱處理的同時沿該等處理區行進,且運送車中之氣體被向下抽吸時,氣體阻擋結構抑制氣體自廢氣循環區及廢氣排放區中之一較低負壓區經由氣體抽吸陣列與運送車之間的間隔流動至廢氣循環區及廢氣排放區中之一較高負壓區。 For example, when an embodiment of the present invention is applied to a sintered ore production process, a gas barrier structure is provided in the bellows arranged in the traveling direction of the transport vehicle and the The adjacent upper ends of the bordered adjacent bellows are on the adjacent upper ends, and the boundaries defined by the adjacent bellows are between the exhaust gas circulation area and the exhaust gas emission area. When the raw materials are loaded on the transport vehicle and the transport vehicle travels along these processing areas while the raw materials are heat-treated, and the gas in the transport vehicle is sucked down, the gas blocking structure inhibits the gas from the exhaust gas circulation area and the exhaust gas. One of the lower negative pressure areas in the emission area flows to the higher negative pressure area in the exhaust gas circulation area and the exhaust gas emission area through the interval between the gas suction array and the delivery vehicle.

在運送車之行進方向上排列之該等風箱中之某些之上部端更向上突出於該等風箱中之其餘者之上部端,其中該等風箱中之該某些相鄰於廢氣循環區與廢氣排放區之間的邊界。此外,氣體阻擋結構可設置於該等相鄰風箱之相鄰上部端上。當原材料被裝載於運送車上而該運送車又在原材料被進行熱處理的同時沿該等處理區行進,且運送車中之氣體被向下抽吸時,變窄之間隙或氣體阻擋結構可抑制氣體自廢氣循環區及廢氣排放區中之一較低負壓區經由氣體抽吸陣列與運送車之間的間隔流動至廢氣循環區及廢氣排放區中之一較高負壓區。 Some of the upper ends of the bellows arranged in the direction of travel of the delivery car project more upwardly from the upper ends of the remaining ones of the bellows, wherein some of the bellows are adjacent to the exhaust gas The boundary between the circulation area and the exhaust emission area. In addition, a gas barrier structure may be disposed on adjacent upper ends of the adjacent bellows. When the raw materials are loaded on the transport vehicle and the transport vehicle travels along these processing areas while the raw materials are heat-treated, and the gas in the transport vehicle is sucked down, the narrowed gap or gas barrier structure can be suppressed The gas flows from a lower negative pressure area in one of the exhaust gas circulation area and the exhaust gas discharge area to a higher negative pressure area in the exhaust gas circulation area and the exhaust gas discharge area through a space between the gas suction array and the transport vehicle.

因此,分別處於廢氣循環區與廢氣排放區中分別位於廢氣循環區與廢氣排放區之邊界處之相鄰風箱中之廢氣可不彼此干擾。因此,可防止氣體自廢氣循環區及廢氣排放區中之較低負壓區回流至廢氣循環區及一廢氣排放區中之較高負壓區。因此,可提高廢氣流之循環流效率及排放流效率二者,且可提高整體廢氣流率。因此,可提高燒結礦石產生製程之效率,且可生產高品質燒結礦石。 Therefore, the exhaust gases in adjacent bellows respectively located in the exhaust gas circulation area and the exhaust gas discharge area at the boundaries of the exhaust gas circulation area and the exhaust gas discharge area may not interfere with each other. Therefore, it is possible to prevent the gas from flowing back from the lower negative pressure area in the exhaust gas circulation area and the exhaust gas discharge area to the higher negative pressure area in the exhaust gas circulation area and an exhaust gas discharge area. Therefore, both the circulating flow efficiency and the exhaust flow efficiency of the exhaust gas flow can be improved, and the overall exhaust gas flow rate can be improved. Therefore, the efficiency of the sintered ore production process can be improved, and high quality sintered ore can be produced.

本發明提供一種廢氣處理設備及方法,其配置當在一燒結機中之廢氣流動被抑制於該機器中的期間而允許在循環流氣體與排放流氣體之間的流干擾,此種流干擾原本可起因於各處理區中之負壓之間的差異(例如,風箱中之負壓之間的差異)。在下文中,將參照一煉鋼廠之一燒結礦石生產製程來詳細地闡述各實施例。顯然,本發明同樣可應用於各種處理系統之廢氣流控制。 The present invention provides an exhaust gas treatment device and method, which are configured to allow flow interference between a circulating flow gas and an exhaust flow gas while the exhaust gas flow in a sintering machine is suppressed in the machine, and such flow interference is originally This can result from differences between negative pressures in each processing zone (eg, differences between negative pressures in the bellows).

參照第1圖,根據本發明一實施例之原材料處理系統包含一運送車10、一原材料漏斗21、一上部燒結礦石漏斗(upper-sintered ore hopper)22、一點火爐30、及一廢氣處理設備400。 Referring to FIG. 1, a raw material processing system according to an embodiment of the present invention includes a transport vehicle 10, a raw material hopper 21, an upper-sintered ore hopper 22, an ignition furnace 30, and an exhaust gas treatment device 400. .

該原材料處理系統可取得一原材料,且在使原材料依序沿複數個處理區移動的同時對其進行熱處理。自該等處理區所產生之至少一部分的廢氣可在該等區之至少一部分中循環。在本說明之上下文中,該系統可係為一燒結機。舉例而言,該系統可係為具有一廢氣再循環構造之一向下抽吸型(downward-suction type)燒結機。 The raw material processing system can obtain a raw material, and heat-process the raw material while sequentially moving it along a plurality of processing zones. At least a portion of the exhaust gas generated from the treatment zones may be circulated in at least a portion of the zones. In the context of this description, the system may be a sintering machine. For example, the system may be a downward-suction type sintering machine having an exhaust gas recirculation structure.

運送車10可配置使得其中之原材料能夠被在多個處理區中進行熱處理。該原材料處理系統包含複數個運送車,該等運送車可在原材料處理系統之延伸方向上連續地排列並耦合於一起。該運送車可配置在該等處理區之排列方向上運行。運送車10在其頂部處開口,且因此在各該運送車中之內部空間內裝載有原材料。這些運送車之內部空間對應於一熱處理空間。原材料可裝載於運送車10內部。 The transport vehicle 10 may be configured so that the raw materials therein can be heat-treated in a plurality of processing zones. The raw material processing system includes a plurality of transport vehicles, which can be continuously arranged and coupled together in the extending direction of the raw material processing system. The transport vehicle can be arranged to run in the arrangement direction of the processing areas. The transport vehicles 10 are open at the top thereof, and thus the raw materials are loaded in the internal space in each of the transport vehicles. The internal space of these transport vehicles corresponds to a heat treatment space. The raw materials can be loaded inside the transport vehicle 10.

運送車10之一底部11可具有其中將複數細長條排列成一柵格(grid)結構之一構造。藉由此種構造,運送車10之內部空間可如稍後所述與一對應風箱進行氣體連通,從而使內部空間中之氣體可通過風箱被向下吸取。 A bottom portion 11 of one of the transport vehicles 10 may have a configuration in which a plurality of elongated strips are arranged in a grid structure. With this configuration, the internal space of the transport vehicle 10 can be in gas communication with a corresponding bellows as described later, so that the gas in the inner space can be sucked down through the bellows.

本系統之一上部端可界定運送車10之一輸送路徑,而本系統 之一下部可界定運送車10之一返回路徑。運送車10沿輸送路徑在一第一方向上行進,且因此,裝載於其中之原材料在被進行熱處理的同時在第一方向上移動。當運送車進入返回路徑時,經熱處理之燒結礦石被卸出至壓碎單元(圖中未顯示)中,並且然後,運送車沿返回路徑在與第一方向相反之一第二方向上行進,且然後可被返回至輸送路徑。 An upper end of the system can define a conveying path of the transport vehicle 10, and the system One of the lower portions may define a return path of the transport vehicle 10. The transport vehicle 10 travels along the conveying path in a first direction, and therefore, the raw materials loaded therein are moved in the first direction while being heat-treated. When the transport vehicle enters the return path, the heat-treated sintered ore is discharged into a crushing unit (not shown in the figure), and then, the transport vehicle travels along the return path in a second direction opposite to the first direction, And then it can be returned to the conveying path.

輸送路徑可包含多個處理區。該等處理區包含:一裝載區,其中定位有原材料漏斗21及上部燒結礦石漏斗22;一點火區,其中定位有點火爐30,位於裝載區之下游;以及一燒結區,位於點火區之下游。裝載區、點火區、及燒結區可沿原材料之移動方向依序排列。 The transport path may include multiple processing zones. The processing areas include: a loading area in which the raw material funnel 21 and the upper sintered ore funnel 22 are located; an ignition area in which an ignition furnace 30 is located downstream of the loading area; and a sintering area located downstream of the ignition area. The loading area, the ignition area, and the sintering area can be sequentially arranged along the moving direction of the raw materials.

裝載區可位於輸送路徑之上游,在此處,原材料開始在輸送路徑中移動。在裝載區中,將原材料裝載於運送車10之內部空間中,藉此在運送車10之內部空間中形成一原材料層。點火區在原材料之移動方向上位於裝載區之下游,且可在原材料之移動方向上延伸。在點火區中,裝載於運送車10中的原材料層之一上部端(在下文中,被稱為一上部材料層)被點火。 The loading area can be located upstream of the conveying path, where the raw materials begin to move in the conveying path. In the loading area, the raw materials are loaded into the inner space of the transport vehicle 10, thereby forming a raw material layer in the inner space of the transport vehicle 10. The ignition area is located downstream of the loading area in the moving direction of the raw material, and can extend in the moving direction of the raw material. In the ignition zone, an upper end (hereinafter, referred to as an upper material layer) of one of the raw material layers loaded in the transport vehicle 10 is ignited.

在燒結區中,使一燃燒空窩自裝載於運送車10上之原材料層之上部材料層移動至原材料層之一下部(在下文中,被稱為一「下部材料層」)。此燒結區係為用於將原材料層進行燒結及冷卻之一區,且在原材料之移動方向上定位於點火區之下游。在各該運送車10使原材料依序沿裝載區、點火區及燒結區移動的同時,各該運送車10中之原材料經受熱處理,藉此產生一燒結礦石。 In the sintering zone, a combustion cavity is moved from a material layer above the raw material layer loaded on the transport vehicle 10 to a lower portion of the raw material layer (hereinafter, referred to as a "lower material layer"). This sintering zone is a zone for sintering and cooling the raw material layer, and is positioned downstream of the ignition zone in the moving direction of the raw material. While each of the transport vehicles 10 sequentially moves the raw materials along the loading area, the ignition area, and the sintering area, the raw materials in each of the transport vehicles 10 are subjected to heat treatment, thereby generating a sintered ore.

原材料漏斗21在其中容納原材料,且位於裝載區中運送車10上方。原材料漏斗21可在其底部開口處具有一裝載滑槽(loading chute)及一筒式進料機(drum feeder),且因此,可將原材料裝載於運送車10內。就 此而言,在裝載之前,漏斗21可使原材料經受垂直離析。 The raw material hopper 21 contains raw materials therein, and is located above the transport vehicle 10 in the loading area. The raw material hopper 21 may have a loading chute and a drum feeder at the bottom opening thereof, and therefore, raw materials may be loaded in the transport vehicle 10. on In this regard, the hopper 21 may subject the raw materials to vertical segregation before loading.

原材料可含有用於燒結礦石生產之一原材料。舉例而言,藉由將鐵源、添加劑及固體燃料進行混合、加濕及粒化,原材料可具有粒度大約為幾毫米之微粒。就此而言,鐵源係為具有鐵組分之源,且可包含鐵礦石及細鐵礦石。添加劑可包含作為含有碳酸鈣之一材料的石灰岩。固體燃料可包含煤系固體燃料,其包含焦炭粉末及無煙煤。 The raw material may contain one of the raw materials used for the production of sintered ore. For example, by mixing, humidifying, and granulating an iron source, an additive, and a solid fuel, the raw material may have particles having a particle size of about several millimeters. In this regard, the iron source is a source having an iron component, and may include iron ore and fine iron ore. The additive may include limestone as one of the materials containing calcium carbonate. The solid fuel may include coal-based solid fuel, which includes coke powder and anthracite.

上部燒結礦石漏斗22位於裝載區中以及在原材料之移動方向上位於原材料漏斗21之上游。可藉由自燒結礦石中選擇粒徑為例如8毫米至15毫米之燒結礦石來提供上部燒結礦石。可在將原材料裝載至運送車10之內部空間之前將上部燒結礦石裝載至運送車10之內部空間中,進而防止原材料附著至運送車10之底部或防止原材料向下穿過在運送車10之底部中界定之間隙。 The upper sintered ore funnel 22 is located in the loading zone and upstream of the raw material hopper 21 in the direction of movement of the raw material. The upper sintered ore may be provided by selecting a sintered ore having a particle diameter of, for example, 8 mm to 15 mm from the sintered ore. The upper sintered ore can be loaded into the inner space of the transport vehicle 10 before the raw materials are loaded into the inner space of the transport vehicle 10, thereby preventing the raw material from adhering to the bottom of the transport vehicle 10 or preventing the raw material from passing downward through the bottom of the transport vehicle Gap defined in.

點火爐30在運送車10之運行方向上與原材料漏斗21間隔開。點火爐30可位於運送車10上方。亦即,點火爐30可位於輸送路徑之點火區中,在運送車10行進之方向上位於原材料漏斗21之下游。配置點火爐30以向下注射火焰,且用於藉由將火焰噴射至上部材料層上而將上部材料層加熱。就此而言,火焰可將上部材料層中所含有之固體燃料點火。 The ignition furnace 30 is spaced from the raw material hopper 21 in the running direction of the transport vehicle 10. The ignition furnace 30 may be located above the transport vehicle 10. That is, the ignition furnace 30 may be located in the ignition area of the conveying path, and downstream of the raw material hopper 21 in the direction in which the transport vehicle 10 travels. The ignition furnace 30 is configured to inject a flame downward, and is used to heat the upper material layer by spraying the flame onto the upper material layer. In this regard, the flame ignites the solid fuel contained in the upper material layer.

在各該運送車10沿該等處理區移動而對該運送車之內部空間中之原材料進行熱處理的同時,根據本發明一實施例配置廢氣處理設備400以自運送車10之內部空間向下吸取氣體並使所吸取氣體之至少一部分在該等處理區之間循環。 While each of the transport vehicles 10 moves along the processing areas to heat-treat the raw materials in the inner space of the transport vehicle, an exhaust gas treatment device 400 is configured to suck downward from the inner space of the transport vehicle 10 according to an embodiment of the present invention. The gas circulates at least a portion of the sucked gas between the processing zones.

參照第1圖及第2圖,根據本發明一實施例之廢氣處理設備 400可包含一氣體阻擋結構413、一氣體抽吸陣列、一氣體通氣管420、一廢氣循環機構、及一廢氣排放機構。 Referring to FIG. 1 and FIG. 2, an exhaust gas treatment device according to an embodiment of the present invention 400 may include a gas blocking structure 413, a gas suction array, a gas vent pipe 420, an exhaust gas circulation mechanism, and an exhaust gas discharge mechanism.

氣體抽吸陣列可設置於運送車10之底部上,且沿運送車10之運送車行進方向延伸。舉例而言,氣體抽吸陣列可在其頂部端包住運送車10之底部的同時在運送車10之運行方向上延伸。更具體而言,氣體抽吸陣列可包含沿運送車10之運送車運行方向排列之複數個風箱410。該等風箱410中之相鄰者可具有在氣體抽吸陣列之延伸方向上彼此並排排列之相鄰上部端。各該風箱410經由在對應運送車10之底部11中界定之間隙與對應運送車10之內部空間進行氣體連通。各該風箱410在對應運送車之內部空間中形成一負壓以將對應運送車10之內部空間中之氣體向下吸取,藉此使得原材料層中之燃燒空窩能夠自原材料層之上部材料層轉移至原材料層之下部材料層。在此過程中,廢氣被收集至該等風箱410中。 The gas suction array may be disposed on the bottom of the transport vehicle 10 and extend along the traveling direction of the transport vehicle 10. For example, the gas suction array may extend in the running direction of the transport vehicle 10 while the top end thereof surrounds the bottom of the transport vehicle 10. More specifically, the gas suction array may include a plurality of bellows 410 arranged along the traveling direction of the transport vehicle 10. Adjacent ones of the bellows 410 may have adjacent upper ends arranged side by side in the extending direction of the gas suction array. Each of the bellows 410 is in gas communication with the internal space of the corresponding transportation vehicle 10 through a gap defined in the bottom 11 of the corresponding transportation vehicle 10. Each of the bellows 410 forms a negative pressure in the internal space of the corresponding transport vehicle to suck down the gas in the internal space of the corresponding transport vehicle 10, thereby enabling the combustion cavity in the raw material layer to be material from the upper part of the raw material layer. The layer is transferred to the material layer below the raw material layer. During this process, the exhaust gas is collected into the bellows 410.

在運送車10經受點火爐30之點火之後,各該運送車在一第一方向上行進且沿氣體抽吸陣列行進。就此而言,氣體抽吸陣列在對應運送車10之內部空間內在向下方向上產生一抽吸力。此抽吸力使運送車10外部之空氣能夠流動至對應運送車10之內部空間中,且然後使內部空間內之氣體能夠被向下汲取,藉此使燃燒空窩向下移動。當對應運送車10穿過燒結區時,燃燒空窩達到運送車10之底部11,藉此完成對原材料層之燒結。在對應運送車10朝向輸送路徑之一終點移動時,燒結礦石已被冷卻。被冷卻之燒結礦石可在輸送路徑之終點處藉由一燒結礦石卸料器卸出。 After the transportation vehicles 10 are subjected to the ignition of the ignition furnace 30, each transportation vehicle travels in a first direction and travels along the gas suction array. In this regard, the gas suction array generates a suction force in a downward direction in the internal space of the corresponding transport vehicle 10. This suction force enables the air outside the transport vehicle 10 to flow into the internal space of the corresponding transport vehicle 10, and then enables the gas in the internal space to be drawn downward, thereby moving the combustion cavity downward. When the corresponding transportation vehicle 10 passes through the sintering zone, the combustion cavity reaches the bottom 11 of the transportation vehicle 10, thereby completing the sintering of the raw material layer. The sintered ore has been cooled when the corresponding transport vehicle 10 moves toward one end of the transport path. The cooled sintered ore can be discharged by a sintered ore discharger at the end of the conveying path.

該等風箱410與運送車10之底部11間隔開一預定間隙。此係為了當在該等風箱410將運送車之內部空間中之氣體向下抽吸時,防止移動的運送車10與風箱410碰撞。此外,在對應運送車穿過各該區時,在各該區 之各點處,運送車之內部空間中之通氣阻力基於原材料之燒結狀態而變化。 出於此種原因,該等風箱410與運送車10之底部11間隔開一預定間隙,以自運送車10之內部空間有效地吸取氣體。亦即,該等風箱410之相鄰且接觸之上部端與運送車10之底部11間隔開一預定距離。 The bellows 410 is spaced from the bottom 11 of the transport vehicle 10 by a predetermined gap. This is to prevent the moving transport vehicle 10 from colliding with the air box 410 when the gas in the inner space of the transport vehicle is sucked downward by the air boxes 410. In addition, when corresponding transport vehicles pass through each of the zones, At each point, the ventilation resistance in the inner space of the delivery vehicle changes based on the sintered state of the raw materials. For this reason, the bellows 410 is spaced a predetermined gap from the bottom 11 of the transport vehicle 10 to efficiently suck gas from the inner space of the transport vehicle 10. That is, the adjacent and contacting upper ends of the bellows 410 are spaced a predetermined distance from the bottom 11 of the transport vehicle 10.

另一方面,氣體抽吸陣列可在其中具有彼此分離的一廢氣循環區Rc及一廢氣排放區Rd。因此,該等風箱410可被劃分成設置於廢氣循環區Rc中之複數風箱411及設置於廢氣排放區Rd中之複數風箱412。 On the other hand, the gas suction array may have an exhaust gas circulation region Rc and an exhaust gas emission region Rd separated from each other. Therefore, the bellows 410 may be divided into a plurality of bellows 411 provided in the exhaust gas circulation region Rc and a plurality of bellows 412 provided in the exhaust gas discharge region Rd.

氣體抽吸陣列之廢氣循環區Rc可對應於氣體抽吸陣列的自燒結區中之一第一點延伸至燒結區中之一第二點的一部分。就此而言,燒結區中之第一點可對應於如下之一點:在該點處,原材料層中之燃燒空窩到達運送車10之底部11,因此完成對原材料層之燒結。燒結區中之第二點可對應於如下之一點:在該點處,燒結原材料層之一通氣阻力值開始降至低於一預定值。 The exhaust gas circulation region Rc of the gas suction array may correspond to a part of the gas suction array extending from a first point in the sintering zone to a second point in the sintering zone. In this regard, the first point in the sintering zone may correspond to one of the following points: At this point, the combustion cavity in the raw material layer reaches the bottom 11 of the transport vehicle 10, and thus the sintering of the raw material layer is completed. The second point in the sintering zone may correspond to a point at which the value of the ventilation resistance of one of the sintered raw material layers begins to fall below a predetermined value.

因此,氣體抽吸陣列之氣體排放區Rd對應於如下二個部分之一組合:氣體抽吸陣列的自輸送路徑之開頭延伸至如上所述燒結區中之第一點的一部分、以及氣體抽吸陣列的自燒結區中之第二點延伸至輸送路徑之終點的一部分。亦即,排放區可對應於氣體抽吸陣列的除循環區以外之其餘部分。 Therefore, the gas discharge region Rd of the gas suction array corresponds to a combination of two parts: a part of the gas suction array extending from the beginning of the conveying path to the first point in the sintering zone as described above, and the gas suction The array extends from a second point in the sintering zone to a portion of the end of the transport path. That is, the discharge area may correspond to the rest of the gas suction array except the circulation area.

如上所述燒結區中之第一點及第二點僅係為用於例示本發明之一實例。本發明並非僅限於此。視製程要求而定,可以各種方式來配置燒結區。此外,廢氣循環區與廢氣排放區之間以上所定義之分界僅係為用於使廢氣循環之各種配置中之一實例。可以各種方式來配置廢氣循環區及廢氣排出區,因此使廢氣以各種方式排出及循環。 The first point and the second point in the sintering zone as described above are merely examples for illustrating the present invention. The invention is not limited to this. Depending on the process requirements, the sintering zone can be configured in various ways. In addition, the boundary defined above between the exhaust gas circulation region and the exhaust gas emission region is only one example of various configurations for circulating the exhaust gas. The exhaust gas circulation area and the exhaust gas discharge area can be configured in various ways, so that the exhaust gas is discharged and circulated in various ways.

在闡述氣體阻擋結構413之前,首先將例示根據本發明一實施例之廢氣處理設備400之氣體通氣管420、廢氣循環機構以及廢氣排放機構。 Before explaining the gas blocking structure 413, the gas vent pipe 420, the exhaust gas circulation mechanism, and the exhaust gas emission mechanism of the exhaust gas treatment apparatus 400 according to an embodiment of the present invention will be exemplified first.

該廢氣處理設備包含複數個氣體通氣管,且該等氣體通氣管被排列成沿氣體抽吸陣列之延伸方向以便彼此間隔開來。該等氣體通氣管可分別與氣體抽吸陣列之底部(即,該等風箱410之底部)連通。氣體通氣管420可被劃分成與設置於廢氣循環區中之風箱411連通之複數氣體通氣管421、以及與設置於廢氣排放區中之風箱412連通之複數氣體通氣管422。 The exhaust gas treatment apparatus includes a plurality of gas vent pipes, and the gas vent pipes are arranged along the extending direction of the gas suction array so as to be spaced apart from each other. The gas vent pipes may communicate with the bottom of the gas suction array (ie, the bottom of the bellows 410), respectively. The gas vent pipe 420 may be divided into a plurality of gas vent pipes 421 communicating with the bellows 411 provided in the exhaust gas circulation area, and a plurality of gas vent pipes 422 communicating with the bellows 412 provided in the exhaust gas discharge area.

廢氣循環機構具有:一第一端部,與氣體通氣管420中之某些(例如,與設置於廢氣循環區中之風箱411連通之氣體通氣管421)連通;以及一第二端部,面向該等處理區內之一預定位置。因此,廢氣循環機構可使自其中燒結原材料層之通氣阻力最大之點吸取之廢氣朝向該等處理區上之預定點循環。 The exhaust gas circulation mechanism has: a first end portion communicating with some of the gas vent pipes 420 (for example, a gas vent pipe 421 communicating with a bellows 411 provided in the exhaust gas circulation area); and a second end portion, Facing one of the predetermined locations in these processing areas. Therefore, the exhaust gas circulation mechanism can circulate the exhaust gas sucked from the point where the ventilation resistance of the sintered raw material layer is the largest toward a predetermined point on the processing areas.

就此而言,廢氣循環機構之第二端部可開口在燒結區之第一點與輸送路徑之終點之間。在一個實施例中,廢氣循環機構之第二端部可開口朝向位於燒結區之上述第一點下游之點。此意味著,廢氣循環機構之第二端部係開口朝向燒結區的其中氧消耗相對較少之下游點。顯然,除上述點以外,廢氣循環機構之第二端部可開口朝向該等處理區上之各點。在下文中,將參照用配置自其中燒結原材料層之通氣阻力最大之點抽吸之廢氣朝向燒結區之下游點循環的廢氣循環機構之一構造。 In this regard, the second end portion of the exhaust gas circulation mechanism may be opened between the first point of the sintering zone and the end point of the conveying path. In one embodiment, the second end portion of the exhaust gas recirculation mechanism may open toward a point located downstream of the first point of the sintering zone. This means that the opening of the second end of the exhaust gas circulation mechanism faces the downstream point of the sintering zone where the oxygen consumption is relatively small. Obviously, in addition to the above points, the second end portion of the exhaust gas recirculation mechanism may be opened toward each point on the processing areas. Hereinafter, a configuration will be referred to one of the exhaust gas circulation mechanisms configured to circulate the exhaust gas sucked from the point where the ventilation resistance of the sintered raw material layer is maximized toward the downstream point of the sintering zone.

廢氣循環機構可包含一循環管430、一循環鼓風機451以及一氣體排放罩460。循環管430之一端與和設置於廢氣循環區中之風箱411連通的氣體通氣管421連通。循環管430之另一端可與氣體排放罩460連通。循環 鼓風機451例如係為用於廢氣循環之一鼓風機。循環鼓風機451安裝於循環管430之一個點上,以使得廢氣能夠自循環管430之一端流動至循環管430之另一端。由於此種流動,一廢氣循環流可被產生在設置於廢氣循環區中之風箱411內。 The exhaust gas circulation mechanism may include a circulation pipe 430, a circulation blower 451, and a gas discharge cover 460. One end of the circulation pipe 430 communicates with a gas vent pipe 421 communicating with a bellows 411 provided in the exhaust gas circulation zone. The other end of the circulation pipe 430 may be in communication with the gas discharge cover 460. cycle The blower 451 is, for example, a blower for exhaust gas circulation. The circulation blower 451 is installed at one point of the circulation pipe 430 so that the exhaust gas can flow from one end of the circulation pipe 430 to the other end of the circulation pipe 430. Due to this flow, an exhaust gas circulating flow can be generated in the wind box 411 provided in the exhaust gas circulating area.

氣體排放罩460可在運送車10之行進方向上以及運送車10上方延伸。氣體排放罩460可在輸送路徑之終點與燒結區中之一中心點之間延伸。氣體排放罩460之下部端係開口的,且氣體排放罩460之下部端面向運送車10。氣體排放罩460之上部端可與循環管430之該另一端連通。氣體排放罩460接收來自循環管430之廢氣,並將氣體供應至運送車10。藉此,廢氣可被循環。 The gas discharge cover 460 may extend in the traveling direction of the transport vehicle 10 and above the transport vehicle 10. The gas exhaust hood 460 may extend between the end of the conveying path and a center point in the sintering zone. The lower end of the gas exhaust hood 460 is open, and the lower end of the gas exhaust hood 460 faces the transport vehicle 10. An upper end of the gas discharge hood 460 may communicate with the other end of the circulation pipe 430. The gas exhaust hood 460 receives exhaust gas from the circulation pipe 430 and supplies the gas to the transport vehicle 10. Thereby, the exhaust gas can be circulated.

在各氣體通氣管420中,未連接至廢氣循環機構之氣體通氣管422可與廢氣排放機構連通。被收集至設置於廢氣排放區中之風箱412中之廢氣可藉由廢氣排放機構排放至大氣。 In each of the gas vent pipes 420, a gas vent pipe 422 that is not connected to the exhaust gas circulation mechanism may communicate with the exhaust gas discharge mechanism. The exhaust gas collected in the wind box 412 provided in the exhaust emission area may be emitted to the atmosphere through the exhaust emission mechanism.

廢氣排放機構具有一第一端部及一第二端部。氣體通氣管420之第一端部與和風箱412連通之第二氣體通氣管群組422連通。第二端部可與大氣空間連通。廢氣排放機構可將被收集至設置於廢氣排放區中之風箱412中之廢氣朝向大氣空間排出。廢氣排放機構可包含一細長排放室440、一污染物收集器470、一主鼓風機452、及一氣體排放模組480。 The exhaust emission mechanism has a first end portion and a second end portion. A first end portion of the gas vent pipe 420 is in communication with a second gas vent pipe group 422 communicating with the bellows 412. The second end portion can communicate with the atmospheric space. The exhaust gas discharging mechanism may discharge the exhaust gas collected in the wind box 412 provided in the exhaust gas discharging area toward the atmospheric space. The exhaust emission mechanism may include an elongated emission chamber 440, a pollutant collector 470, a main blower 452, and a gas emission module 480.

細長排放室440可係為中空的。細長排放室440之一端可連接至氣體通氣管422,氣體通氣管422與設置於廢氣排放區中之風箱412連通。 細長排放室440之另一端可連接至氣體排放模組480。主鼓風機452例如係為用於排放廢氣之一鼓風機,且安裝於排放室440之一預定位置處。主鼓風機452可自排放室440之一端至排放室440之另一端產生廢氣的流動。藉由此種 流動,廢氣流可產生在設置於廢氣排放區中之風箱412中。廢氣可含有例如粉塵、氮氧化物及硫氧化物等污染物。為過濾出此等污染物,在廢氣流方向上主鼓風機452之上游存在污染物收集器470。污染物收集器470可安裝於排放室440之一預定位置處。 The elongated discharge chamber 440 may be hollow. One end of the elongated discharge chamber 440 may be connected to a gas vent pipe 422, and the gas vent pipe 422 communicates with a bellows 412 provided in the exhaust gas discharge area. The other end of the elongated discharge chamber 440 may be connected to a gas discharge module 480. The main blower 452 is, for example, a blower for discharging exhaust gas, and is installed at a predetermined position of the discharge chamber 440. The main blower 452 may generate a flow of exhaust gas from one end of the discharge chamber 440 to the other end of the discharge chamber 440. By this Flow, the exhaust gas flow may be generated in a wind box 412 provided in the exhaust gas discharge area. The exhaust gas may contain pollutants such as dust, nitrogen oxides, and sulfur oxides. To filter out these pollutants, a pollutant collector 470 exists upstream of the main blower 452 in the direction of the exhaust gas flow. The pollutant collector 470 may be installed at one predetermined position of the discharge chamber 440.

一壓碎單元(圖中未顯示)可設置於燒結區之下游。通過該壓碎單元將自運送車10卸出之燒結礦石壓碎成一預定粒度,且然後,被壓碎之礦石在一網篩(圖中未顯示)處進行篩分。被篩分之燒結礦石基於其粒徑而可被饋送至其他製程(例如一鼓風爐製程)、可用作上部燒結礦石、或可重新用作原材料。 A crushing unit (not shown) may be disposed downstream of the sintering zone. The sintered ore discharged from the transport vehicle 10 is crushed into a predetermined particle size by the crushing unit, and then the crushed ore is sieved at a mesh screen (not shown in the figure). The sieved sintered ore can be fed to other processes (such as a blast furnace process) based on its particle size, can be used as an upper sintered ore, or can be reused as a raw material.

同時,主鼓風機452與循環鼓風機451具有不同的抽吸位置及抽吸面積。亦即,主鼓風機452與循環鼓風機451在其所必須作用於的風箱之位置及數目方面係為不同的。另外,以下二者亦係為不同的:在連接至主鼓風機452之風箱412上且沿該等風箱412移動之運送車10內之原材料層之一通氣水準、與在連接至循環鼓風機451之風箱411上且沿該等風箱411移動的成陣列之運送車10內之原材料層之一通氣水準。由於此等差異,主鼓風機452與循環鼓風機451具有不同的操作壓力。 Meanwhile, the main blower 452 and the circulation blower 451 have different suction positions and suction areas. That is, the main blower 452 and the circulation blower 451 are different in the position and number of the bellows to which they must act. In addition, the following two are also different: one of the raw material layers in the conveyer 10 connected to the air box 412 connected to the main blower 452 and moving along the air box 412, and connected to the circulation blower 451 One of the raw material layers on the air box 411 and moving along the air box 411 in the array of the transport vehicles 10 is at a level of ventilation. Due to these differences, the main blower 452 and the circulation blower 451 have different operating pressures.

因此,由主鼓風機452對設置於廢氣排放區中之風箱412施加之負壓,與由循環鼓風機451對設置於廢氣循環區中之風箱411施加之負壓係為彼此不同的。由主鼓風機452吸取之一廢氣量與由循環鼓風機451吸取之一廢氣量亦係為不同的。舉例而言,由循環鼓風機451對設置於廢氣循環區中之風箱411施加之負壓之量值可大於由主鼓風機452對設置於廢氣排放區中之風箱412施加之負壓之量值。當然,相反情況亦可成立。亦即,廢氣排放區中之負壓之量值可能更大。 Therefore, the negative pressure applied by the main blower 452 to the bellows 412 provided in the exhaust gas discharge area is different from the negative pressure applied by the circulation blower 451 to the bellows 411 provided in the exhaust gas circulation area. An amount of exhaust gas sucked by the main blower 452 and an amount of exhaust gas sucked by the circulation blower 451 are also different. For example, the amount of negative pressure applied by the circulation blower 451 to the air box 411 provided in the exhaust gas circulation area may be greater than the amount of negative pressure applied by the main blower 452 to the air box 412 provided in the exhaust gas discharge area . Of course, the opposite is also true. That is, the magnitude of the negative pressure in the exhaust gas emission area may be larger.

在此種情形中,低負壓區中之廢氣可回流朝向高負壓區。亦即,在廢氣循環區與廢氣排放區之間的邊界處具有不同的負壓,在各廢氣流之間的干擾可能會發生,進而使得廢氣的回流至具有一高負壓之區域。回流的廢氣可經由運送車10之底部11與氣體抽吸陣列之間的間隙流動至高負壓區中。 In this case, the exhaust gas in the low negative pressure region can flow back toward the high negative pressure region. That is, there are different negative pressures at the boundary between the exhaust gas circulation area and the exhaust gas emission area, and interference between the exhaust gas flows may occur, thereby causing the exhaust gas to return to a region with a high negative pressure. The returned exhaust gas can flow into the high negative pressure region through the gap between the bottom 11 of the transport vehicle 10 and the gas suction array.

如此一來,因主鼓風機452與循環鼓風機451之間在操作壓力及抽吸力的至少其中之一上之差異,必須被排放至廢氣排放區之廢氣之一部分可在氣體抽吸陣列之廢氣排放區與廢氣循環區之間的邊界處回流至具有一較高負壓之廢氣循環區中。因此,主鼓風機452之廢氣抽吸量降低。此種現象被稱為主鼓風機452與循環鼓風機451之間的流干擾(flow-interference)。 In this way, due to the difference between the main blower 452 and the circulation blower 451 in at least one of the operating pressure and the suction force, a part of the exhaust gas that must be discharged into the exhaust gas discharge area can be discharged in the exhaust gas of the gas suction array The boundary between the zone and the exhaust gas recirculation zone flows back into the exhaust gas recirculation zone with a higher negative pressure. Therefore, the exhaust gas suction amount of the main blower 452 is reduced. This phenomenon is called flow-interference between the main blower 452 and the circulation blower 451.

根據本發明之實施例,為在氣體抽吸陣列之廢氣排放區與廢氣循環區之間的邊界處抑制主鼓風機452與循環鼓風機451之間的流干擾,氣體阻擋結構413可形成在該邊界處,以減小運送車10與氣體抽吸陣列之間的間隙。 According to the embodiment of the present invention, in order to suppress the flow interference between the main blower 452 and the circulation blower 451 at the boundary between the exhaust gas exhaust area and the exhaust gas circulation area of the gas suction array, the gas blocking structure 413 may be formed at the boundary To reduce the gap between the transport cart 10 and the gas suction array.

參照第2圖,氣體阻擋結構413在與運送車10之運行方向交叉之一方向上延伸。例如,氣體阻擋結構413可被形成為一塊形狀。氣體阻擋結構413可設置於與邊界相鄰的該等風箱中之某些之相鄰上部端上,而該等相鄰風箱界定廢氣循環區與廢氣排放區之間的邊界。 Referring to FIG. 2, the gas blocking structure 413 extends in a direction crossing the running direction of the transport vehicle 10. For example, the gas blocking structure 413 may be formed in a block shape. The gas blocking structure 413 may be disposed on an adjacent upper end of some of the wind boxes adjacent to the boundary, and the adjacent wind boxes define a boundary between the exhaust gas circulation area and the exhaust gas emission area.

就此而言,於一容差範圍內,氣體阻擋結構413之頂部與運送車10之底部之間的間隙可大於0毫米但小於或等於100毫米。此處,公差範圍可係指因量測構件之一機械誤差或電子誤差而引起的一公差。另一選擇為,公差範圍可係指能夠防止因運送車10之底部11及氣體阻擋結構413之結 構性變形而在運送車10與氣體阻擋結構413之間發生結構性碰撞之一最小餘隙。 In this regard, within a tolerance range, the gap between the top of the gas blocking structure 413 and the bottom of the transport vehicle 10 may be greater than 0 mm but less than or equal to 100 mm. Here, the tolerance range may refer to a tolerance caused by a mechanical error or an electronic error of a measurement component. Alternatively, the tolerance range may refer to the ability to prevent the bottom 11 of the transport vehicle 10 and the gas barrier structure 413 from binding. One of the minimum clearances for a structural collision between the transport vehicle 10 and the gas barrier structure 413 due to structural deformation.

在廢氣排放區與廢氣循環區之間的邊界處,氣體阻擋結構413可使運送車10之底部11與風箱之上部端之間的間隙變窄。亦即,氣體阻擋結構413可穿過該間隙達成一實質上氣體阻擋效應。因此,氣體自低負壓區至高負壓區之回流可得以抑制。在不具有氣體阻擋結構413之其他位置處,廢氣可自由地流動穿過運送車10之底部11與風箱之頂部之間的間隔。因此,在廢氣排放區及廢氣循環區中之每一者中,可穩定地達成對廢氣之抽吸。 At the boundary between the exhaust gas emission area and the exhaust gas circulation area, the gas blocking structure 413 can narrow the gap between the bottom 11 of the transport vehicle 10 and the upper end of the bellows. That is, the gas barrier structure 413 can pass through the gap to achieve a substantially gas barrier effect. Therefore, the backflow of the gas from the low negative pressure region to the high negative pressure region can be suppressed. At other locations without the gas barrier structure 413, the exhaust gas can flow freely through the space between the bottom 11 of the transport vehicle 10 and the top of the bellows. Therefore, in each of the exhaust emission region and the exhaust gas circulation region, the exhaust gas can be stably achieved.

根據本發明實施例之氣體阻擋結構413可包含如下所述之各種改良。 The gas barrier structure 413 according to the embodiment of the present invention may include various improvements as described below.

參照第3圖,根據本發明一第一改型實施例之一氣體阻擋結構413A可包含:一氣體阻擋本體413',在一垂直方向上伸出且在與垂直方向及運送車10之運行方向二者交叉之一方向上延伸;以及一翼片414,呈一翅或板之一形式,自氣體阻擋本體413'在運送車10之運行方向上延伸。就此而言,翼片414可自氣體阻擋本體413'之上部端水平地延伸。 Referring to FIG. 3, a gas blocking structure 413A according to a first modified embodiment of the present invention may include: a gas blocking body 413 ′, which extends in a vertical direction and is perpendicular to the vertical direction and the running direction of the transport vehicle 10 The two extend in one direction; and a wing 414, which is in the form of a fin or a plate, extends from the gas blocking body 413 'in the running direction of the transport vehicle 10. In this regard, the fin 414 may extend horizontally from the upper end of the gas blocking body 413 '.

翼片414在其翼片414所在之風箱上方界定一氣體流阻擋面,以使得可直接防止廢氣自較低負壓區(例如,廢氣排放區)至較高負壓區(例如,廢氣循環區)的回流。亦即,在流體動力學方面,翼片414具有顯著的重要性。以下將結合對根據本發明實施例之氣體抽吸陣列內及根據一比較例之一氣體抽吸陣列內廢氣流之數值分析來對此進行說明。 The airfoil 414 defines a gas flow blocking surface above the air box where the airfoil 414 is located, so that the exhaust gas can be directly prevented from the lower negative pressure area (for example, the exhaust gas emission area) to the higher negative pressure area (for example, the exhaust gas circulation) Zone). That is, in terms of fluid dynamics, the fin 414 has significant importance. In the following, a numerical analysis of the exhaust gas flow in a gas suction array according to an embodiment of the present invention and in a gas suction array according to a comparative example will be described.

翼片414可用以接收並支撐經由在運送車10之底部11中界定 之開口而落下之原材料,藉此進一步使運送車10與氣體抽吸陣列之間的間隙變窄。如此一來,可在廢氣排放區與廢氣循環區之間的邊界處達成更有效之氣體流阻擋。 The flaps 414 can be used to receive and support via the bottom 11 defined in the transport vehicle 10 The raw materials dropped by the openings further narrow the gap between the transport cart 10 and the gas suction array. In this way, a more effective gas flow blocking can be achieved at the boundary between the exhaust emission area and the exhaust gas circulation area.

參照第5圖,根據本發明一第三改型實施例之一氣體阻擋結構413C可與上述第一改型之氣體阻擋結構413A在翼片414之高度方面不同。 亦即,根據本發明第三改型實施例之氣體阻擋結構413C可包含:一氣體阻擋本體413',在一垂直方向上伸出且在與垂直方向及運送車10之運行方向二者交叉之一方向上延伸;以及一翼片414,呈一翅或板之一形式,自氣體阻擋本體413'之一下部在運送車10之運行方向上延伸。 Referring to FIG. 5, a gas blocking structure 413C according to a third modified embodiment of the present invention may be different from the gas blocking structure 413A of the first modification in the height of the fin 414. That is, the gas blocking structure 413C according to the third modified embodiment of the present invention may include a gas blocking body 413 ′ protruding in a vertical direction and intersecting with both the vertical direction and the running direction of the transport vehicle 10. Extending in one direction; and a wing 414, which is in the form of a fin or a plate, extends from a lower portion of the gas blocking body 413 'in the running direction of the transport vehicle 10.

如此一來,在本發明之各種改型中,翼片414可自氣體阻擋本體413'之頂部或底部延伸出,或者可自氣體阻擋本體413'之頂部與底部之間的一中間部延伸出。亦即,翼片414可自氣體阻擋本體413'之各種高度延伸出。 As such, in various modifications of the present invention, the fins 414 may extend from the top or bottom of the gas blocking body 413 ', or may extend from a middle portion between the top and the bottom of the gas blocking body 413'. . That is, the fins 414 can extend from various heights of the gas blocking body 413 '.

參照第3圖及第5圖,翼片414可位於氣體循環區及廢氣排放區的至少其中之一中的一風箱中。就此而言,翼片可位於廢氣循環區及廢氣排放區中之較低負壓區之風箱中。此外,在稍後所述之一第四改型之氣體阻擋結構413D中以及稍後所述之一第五改型之一氣體阻擋結構413E中,一翼片414可位於廢氣循環區及廢氣排放區中具有較低負壓之區之風箱中。就此而言,本發明之第一改型、第三改型、第四改型、及第五改型例示位於作為較低負壓區之廢氣排放區之風箱中之翼片414。 Referring to FIGS. 3 and 5, the fin 414 may be located in a bellows in at least one of a gas circulation area and an exhaust gas emission area. In this regard, the fins may be located in a bellows in a lower negative pressure region in the exhaust gas circulation region and the exhaust gas emission region. In addition, in a fourth modification of the gas barrier structure 413D described later and a fifth modification of the gas barrier structure 413E described later, a fin 414 may be located in the exhaust gas circulation area and the exhaust gas emission area. In a bellows with a lower negative pressure. In this regard, the first modification, the third modification, the fourth modification, and the fifth modification of the present invention exemplify the fins 414 located in the wind box as an exhaust gas emission region of a lower negative pressure region.

相反,參照第4圖,根據本發明一第二改型實施例之一氣體阻擋結構413B可包含分別位於廢氣循環區之一風箱及廢氣排放區之一風箱中之一對翼片414。換言之,根據本發明第二改型實施例之氣體阻擋結構 413B可包含:一氣體阻擋本體413',在與運送車10之運行方向交叉之一方向上延伸;一對翼片414,呈一翅或板之一形式且自氣體阻擋本體413'之一上部端在運送車10之運行方向上伸出,並且分別設置於廢氣循環區及廢氣排放區中。 In contrast, referring to FIG. 4, a gas blocking structure 413B according to a second modified embodiment of the present invention may include a pair of fins 414 respectively located in a bellows of an exhaust gas circulation region and a bellows of an exhaust gas emission region. In other words, the gas barrier structure according to the second modified embodiment of the present invention 413B may include: a gas blocking body 413 'extending in a direction that intersects with the running direction of the transport vehicle 10; a pair of fins 414 in the form of a wing or a plate and extending from an upper end of the gas blocking body 413' It protrudes in the running direction of the transport vehicle 10 and is disposed in the exhaust gas circulation area and the exhaust gas discharge area, respectively.

顯然,除如上所述之改型之外,本發明之實施例可更包含各種改型,其中包括使一翼片414僅位於廢氣循環區及廢氣排放區中之較高負壓區之一風箱中。亦即,根據本發明改型之翼片414可位於廢氣循環區及廢氣排放區的至少其中之一的一風箱中。 Obviously, in addition to the modifications described above, the embodiments of the present invention may further include various modifications, including making a fin 414 located only in one of the higher negative pressure region in the exhaust gas circulation area and the exhaust gas discharge area. in. That is, the modified fin 414 according to the present invention may be located in an air box of at least one of the exhaust gas circulation area and the exhaust gas discharge area.

根據本發明之改型,當面向翼片414之風箱之頂部之寬度被設定成1時,翼片之延伸長度可大於0且小於或等於2/3。若翼片414之延伸長度相對於面向翼片414之風箱之頂部之寬度1而言超過2/3時,則防止廢氣回流之效果變大,但進入面向翼片之風箱中之廢氣流可係為不良的。出於此種原因,相對於面向翼片414之風箱之頂部之寬度1而言,翼片414之延伸長度等於或小於2/3。 According to a modification of the present invention, when the width of the top of the bellows facing the flap 414 is set to 1, the extension length of the flap may be greater than 0 and less than or equal to 2/3. If the extension length of the fin 414 is more than 2/3 with respect to the width 1 of the top of the air box facing the wing 414, the effect of preventing exhaust gas from flowing back becomes greater, but the exhaust gas flow into the air box facing the wing Can be bad. For this reason, the extension length of the fins 414 is equal to or less than 2/3 with respect to the width 1 of the top of the bellows facing the fins 414.

參照第6圖,根據本發明第四改型實施例之一氣體阻擋結構413D可更包含自翼片414之一頂面向上突出之至少一個凸肋415。亦即,根據本發明第四改型實施例之氣體阻擋結構413D可包含:一氣體阻擋本體413',在一垂直方向上伸出且在與垂直方向及運送車10之運行方向二者交叉之一方向上延伸;一翼片414,呈一翅或板之一形式,自氣體阻擋本體413'之一下部在運送車10之運行方向上朝向廢氣排放區之一風箱延伸;以及至少一個凸肋415,自翼片414之一頂面向上突出。 Referring to FIG. 6, a gas blocking structure 413D according to a fourth modified embodiment of the present invention may further include at least one rib 415 protruding upward from a top surface of the wing 414. That is, the gas blocking structure 413D according to the fourth modified embodiment of the present invention may include a gas blocking body 413 ′ protruding in a vertical direction and intersecting with both the vertical direction and the running direction of the transport vehicle 10. Extending in one direction; a wing 414 in the form of a fin or a plate extending from a lower portion of the gas blocking body 413 ′ toward a bellows of the exhaust gas discharge area in the running direction of the transport vehicle 10; and at least one rib 415 , Protruding upward from one of the fins 414.

就此而言,在第6圖中,顯示僅設置於廢氣排放區之風箱中且自氣體阻擋本體413'之下部延伸出之翼片414。本發明並非僅限於此。根 據本發明第四改型之翼片414可僅位於廢氣循環區之風箱中,或者可位於廢氣排放區之風箱及廢氣循環區之風箱中之每一者中。另外,如上所述之翼片414可自具有不同高度之部分(包括氣體阻擋本體413'之上部及下部)延伸出。 In this regard, in FIG. 6, a fin 414 that is provided only in a bellows of an exhaust gas emission area and extends from a lower portion of the gas blocking body 413 ′ is shown. The invention is not limited to this. root The wing 414 according to the fourth modification of the present invention may be located only in the wind box of the exhaust gas circulation area, or may be located in each of the wind box of the exhaust gas discharge area and the wind box of the exhaust gas circulation area. In addition, as described above, the fins 414 can extend from portions having different heights (including the upper and lower portions of the gas blocking body 413 ').

凸肋415可係為複數,且可在運送車之行進方向上或在與垂直方向及運送車之行進方向二者交叉之一方向上延伸。就此而言,該等凸肋415中之某些在運送車之運行方向上延伸,而該等凸肋415中之其餘者在與垂直方向及運送車之運行方向二者交叉之一方向上延伸,藉此可達成一柵格結構。藉由使用此種柵格結構,下落至翼片414之頂表面上之原材料可容置於該柵格結構中,藉此抑制或防止廢氣回流。 The convex ribs 415 may be plural, and may extend in a traveling direction of the transport vehicle or in a direction crossing one of the vertical direction and the traveling direction of the transport vehicle. In this regard, some of the ribs 415 extend in the running direction of the transport vehicle, and the rest of the ribs 415 extend in one of the directions intersecting with both the vertical direction and the running direction of the transport vehicle, In this way, a grid structure can be achieved. By using such a grid structure, the raw materials falling on the top surface of the fin 414 can be accommodated in the grid structure, thereby suppressing or preventing backflow of exhaust gas.

另外,上述凸肋415朝向在翼片414之頂表面上流動之廢氣強加流阻,且可抑制廢氣自低負壓區流動至高負壓區。 In addition, the above-mentioned rib 415 imposes a flow resistance toward the exhaust gas flowing on the top surface of the fin 414, and can suppress the exhaust gas from flowing from the low negative pressure region to the high negative pressure region.

參照第7圖,根據本發明第五改型之一氣體阻擋結構413E可更包含自翼片414之一遠端以一傾斜方式向下伸出之一尖端部416。亦即,氣體阻擋結構413E可包含:一氣體阻擋本體413',在一垂直方向上伸出且在與垂直方向及運送車10之運行方向二者交叉之一方向上延伸;一翼片414,呈一翅或板之一形式,自氣體阻擋本體413'之一上部端在運送車10之運行方向上朝向廢氣排放區之一風箱延伸;以及一尖端部416,被形成為自翼片414之一遠端在自本體413'至翼片414之一端的一方向上以一傾斜方式向下伸出。 Referring to FIG. 7, a gas blocking structure 413E according to a fifth modification of the present invention may further include a tip portion 416 protruding downward from a distal end of the wing 414 in an inclined manner. That is, the gas blocking structure 413E may include: a gas blocking body 413 ′ protruding in a vertical direction and extending in a direction that intersects with the vertical direction and the running direction of the transport vehicle 10; a wing 414 showing a One of the forms of fins or plates extending from an upper end of the gas blocking body 413 ′ toward a bellows of the exhaust gas discharge area in the running direction of the transport vehicle 10; and a tip portion 416 formed as one of the self-fins 414 The distal end protrudes downward in an inclined manner from one side of the body 413 'to one end of the tab 414.

由於尖端部416,能夠可靠地確保面向翼片414之風箱中具有一較大氣體流阻擋面積,同時可防止在氣體阻擋結構與運送車之底部11之間發生碰撞。舉例而言,當面向翼片414之風箱之上部端之橫截面積被設定成1時,在運送車之行進方向上翼片414與尖端部416之一總延伸長度可大於 0且小於或等於2/3。 Due to the tip portion 416, a large gas flow blocking area can be reliably ensured in the air box facing the fin 414, and a collision between the gas blocking structure and the bottom portion 11 of the transport vehicle can be prevented. For example, when the cross-sectional area of the upper end of the bellows facing the flap 414 is set to 1, the total extension length of one of the flap 414 and the tip portion 416 in the traveling direction of the transport vehicle may be greater than 0 and less than or equal to 2/3.

根據上述改型之氣體阻擋結構之各特徵可被彼此替代或彼此組合,以形成氣體阻擋結構之各種構造。 The features of the gas barrier structure according to the above modification may be replaced or combined with each other to form various configurations of the gas barrier structure.

根據本發明之另一實施例(第二實施例),一種用於一原材料處理系統之廢氣處理設備可如下變化:該廢氣處理設備可包含:複數個風箱,沿一運送車之一移動方向排列且設置於該運送車下方,其中該運送車被設置成在其中容納一原材料的同時沿複數個處理區移動,其中該等風箱具有彼此分離的一廢氣循環區及一廢氣排放區,其中該等風箱中之某些之上部端相較該等風箱中之其餘者之上部端更向上突出,其中該等風箱中之該某些相鄰於廢氣循環區與廢氣排放區之間的邊界。 According to another embodiment (second embodiment) of the present invention, an exhaust gas treatment equipment for a raw material processing system may be changed as follows: The exhaust gas treatment equipment may include: a plurality of bellows, moving along one of a transport vehicle They are arranged and arranged below the transport vehicle, wherein the transport vehicle is arranged to move along a plurality of processing areas while accommodating a raw material therein, wherein the bellows has an exhaust gas circulation area and an exhaust gas emission area separated from each other, wherein Some of the upper ends of the bellows project more upwards than the upper ends of the remaining ones of the bellows, wherein some of the bellows are adjacent to the exhaust gas circulation area and the exhaust gas emission area The border.

在一個實施例中,該等風箱中之該某些包括一第一風箱及一第二風箱,且該第一風箱及該第二風箱在其之間界定該邊界並分別設置於該廢氣循環區及該廢氣排放區中,其中於一誤差範圍內,該第一風箱及該第二風箱之上部端與該運送車之一底面之間的一間隔可處於0毫米至100毫米且不包含0毫米而包含100毫米之一範圍中。 In one embodiment, some of the bellows include a first bellows and a second bellows, and the first bellows and the second bellows define the boundary therebetween and are provided respectively In the exhaust gas circulation area and the exhaust gas emission area, within a tolerance range, an interval between the upper ends of the first and second wind boxes and a bottom surface of the transport vehicle may be between 0 mm and 100 millimeters and not including 0 millimeters but within a range of 100 millimeters.

在此種情形中,在廢氣排放區與廢氣循環區之間的邊界處,有一氣體阻擋結構設置在第一風箱與第二風箱處以及在第一風箱與第二風箱之間,以減小運送車之底部與風箱之間的間隙、更具體而言運送車之底部與第一風箱及第二風箱之上部端之間的間隙。就此而言,氣體阻擋結構之構造可與根據本發明上述實施例之氣體阻擋結構之構造相同或類似。此實施例中之廢氣處理設備之其餘組件可與本發明上述實施例之其餘組件類似或相同。 In this case, at the boundary between the exhaust emission area and the exhaust gas circulation area, a gas blocking structure is provided at the first and second wind boxes, and between the first and second wind boxes, In order to reduce the gap between the bottom of the transport cart and the bellows, more specifically the gap between the bottom of the transport cart and the upper ends of the first and second bellows. In this regard, the configuration of the gas barrier structure may be the same as or similar to that of the gas barrier structure according to the above-mentioned embodiment of the present invention. The remaining components of the exhaust gas treatment device in this embodiment may be similar to or the same as the remaining components of the above embodiment of the present invention.

根據本發明第二實施例之氣體阻擋結構可包含各種改型。就此而言,根據本發明第二實施例之改型之氣體阻擋結構之構造及操作可與根據本發明第一實施例之上述改型之氣體阻擋結構之構造及操作相同或類似。 The gas barrier structure according to the second embodiment of the present invention may include various modifications. In this regard, the configuration and operation of the modified gas barrier structure according to the second embodiment of the present invention may be the same as or similar to the configuration and operation of the modified gas barrier structure according to the first embodiment of the present invention.

第8圖係為顯示根據一比較例之用於一氣體抽吸陣列之廢氣流之示意圖。就此而言,根據該比較例之氣體抽吸陣列不具有一氣體阻擋結構,且因此,如同在傳統方法中,氣體抽吸陣列與運送車之間的一間隙例如大於100毫米。 FIG. 8 is a schematic diagram showing an exhaust gas flow for a gas suction array according to a comparative example. In this regard, the gas suction array according to the comparative example does not have a gas barrier structure, and therefore, as in the conventional method, a gap between the gas suction array and the transportation vehicle is, for example, greater than 100 mm.

參照第8圖,在該比較例中,不存在氣體阻擋結構,進而使得廢氣可經由廢氣排放區與廢氣循環區之間的邊界而回流。此外,穿過原材料層之廢氣可集中於為一高負壓區之廢氣循環區上。因此,當發生此種流干擾時,與廢氣排放區連通之主鼓風機之廢氣抽吸量會減小,且因此,製程效率可降低。 Referring to FIG. 8, in this comparative example, there is no gas blocking structure, so that the exhaust gas can flow back through the boundary between the exhaust emission region and the exhaust gas circulation region. In addition, the exhaust gas passing through the raw material layer can be concentrated on the exhaust gas circulation area which is a high negative pressure area. Therefore, when such flow disturbance occurs, the exhaust gas suction amount of the main blower communicating with the exhaust gas discharge area is reduced, and therefore, the process efficiency can be reduced.

舉例而言,關於一傳統燒結機,在風箱與運送車之間存在足以使得廢氣能夠從中流過之一餘隙,如第8圖中所示。當對具有此種構造之燒結機應用燒結廢氣循環方法且增加燒結機之焙燒面積時,以一單個鼓風機無法可靠地達成廢氣控制,且因此,必須安裝附加鼓風機。當操作複數個鼓風機時,廢氣可經由以上所定義之間隙往回流動,且廢氣控制效率可降低。在操作該等鼓風機之一燒結機中,在連接至不同鼓風機之各風箱之間應不存在廢氣轉移,以使得廢氣控制得以有效地執行。 For example, with regard to a conventional sintering machine, there is a clearance between the bellows and the transport vehicle sufficient to allow the exhaust gas to flow therethrough, as shown in FIG. 8. When a sintering exhaust gas circulation method is applied to a sintering machine having such a structure and the firing area of the sintering machine is increased, exhaust gas control cannot be reliably achieved with a single blower, and therefore, an additional blower must be installed. When multiple blowers are operated, the exhaust gas can flow back through the gap defined above, and the exhaust gas control efficiency can be reduced. In operating a sintering machine of one of these blowers, there should be no exhaust gas transfer between the bellows connected to different blowers, so that exhaust gas control can be effectively performed.

在本發明之實施例及其改型中,使用二或更多個鼓風機之一燒結機可使用氣體阻擋結構來高效地控制廢氣。為例示根據本發明實施例之氣體阻擋結構之效果,將對比較例與本發明實施例之氣體抽吸陣列中之 廢氣流進行數值分析且將陳述其結果。 In an embodiment of the present invention and a modification thereof, a sintering machine using one of two or more blowers may use a gas blocking structure to efficiently control exhaust gas. As an example to show the effect of the gas barrier structure according to the embodiment of the present invention, the gas suction array in the comparative example and the embodiment of the present invention will be compared. The exhaust gas flow is numerically analyzed and its results will be stated.

第9圖係為例示根據本發明實施例及比較例對氣體抽吸陣列中之廢氣流進行之數值分析的圖示。第9圖之(a)顯示根據比較例,在廢氣排放區與廢氣循環區之間的邊界處之氣體抽吸陣列內部之廢氣流之一數值分析結果。第9圖之(b)顯示根據本發明一個實施例,在廢氣排放區與廢氣循環區之間的邊界處之氣體抽吸陣列內部之廢氣流之一數值分析結果。第9圖之(c)顯示根據本發明第一改型,當使用包含一氣體阻擋本體及一個翼片之一氣體阻擋結構時,在廢氣排放區與廢氣循環區之間的邊界處之氣體抽吸陣列內部之廢氣流之一數值分析結果。 FIG. 9 is a diagram illustrating numerical analysis of exhaust gas flow in a gas suction array according to an embodiment of the present invention and a comparative example. (A) of FIG. 9 shows a numerical analysis result of one of the exhaust gas flows inside the gas suction array at the boundary between the exhaust gas emission area and the exhaust gas circulation area according to the comparative example. FIG. 9 (b) shows a numerical analysis result of one of the exhaust gas flows inside the gas suction array at the boundary between the exhaust emission area and the exhaust gas circulation area according to an embodiment of the present invention. (C) of FIG. 9 shows that according to the first modification of the present invention, when a gas barrier structure including a gas barrier body and a fin is used, the gas extraction at the boundary between the exhaust gas emission area and the exhaust gas circulation area Numerical analysis of one of the exhaust gas flows inside the suction array.

亦即,第9圖之(a)至(c)顯示基於是否存在氣體阻擋本體以及是否存在翼片對廢氣流之流分析結果。就此而言,主鼓風機452與循環鼓風機451之間的一壓力差被設定成200毫米水柱(mmAq),且循環鼓風機451具有一較高負壓。在對第9圖之(a)與(b)之間進行之比較中,關於比較例,可確認來自廢氣排放區之廢氣強制性地回流至廢氣循環區中,而關於本發明之實施例,可看出此種廢氣回流被明顯減弱。 That is, (a) to (c) of FIG. 9 show the flow analysis results of the exhaust gas flow based on the presence or absence of the gas blocking body and the presence or absence of the fins. In this regard, a pressure difference between the main blower 452 and the circulation blower 451 is set to 200 millimeters of water (mmAq), and the circulation blower 451 has a relatively high negative pressure. In the comparison between (a) and (b) of FIG. 9, regarding the comparative example, it can be confirmed that the exhaust gas from the exhaust gas emission area is forcedly returned to the exhaust gas circulation area, and regarding the embodiment of the present invention, It can be seen that such exhaust gas backflow is significantly reduced.

就此而言,回流往廢氣循環區之廢氣被明顯減弱,但在廢氣阻擋結構上之廢氣之一部分仍朝向廢氣循環區偏流。就此而言,此種廢氣流偏流可始於運送車內部。此乃因運送車中之原材料層具有空隙,原材料層中之廢氣經由該等空隙可輕易地朝向廢氣循環區偏流。 In this regard, the exhaust gas flowing back to the exhaust gas circulation area is significantly weakened, but a part of the exhaust gas on the exhaust gas blocking structure still deflects toward the exhaust gas circulation area. In this regard, such a biased flow of exhaust gas flow can begin inside the transport vehicle. This is because the raw material layer in the transport vehicle has voids, and the exhaust gas in the raw material layer can easily divert toward the exhaust gas circulation area through these gaps.

同時,由於運送車保持運行,因而氣體阻擋結構必須與運送車之底部間隔開某一距離。自原材料層內部起,偏流的廢氣可沿氣體阻擋結構之頂面流動至廢氣循環區中。在本發明之改型中,為禁止或防止偏流,氣體阻擋結構具有翼片。該翼片在運送車之行進方向上延伸。使用此種翼片結 構,沿氣體阻擋結構以及位於氣體阻擋結構上之廢氣流不會偏流,而是被實質上均等地劃分至廢氣排放區及廢氣循環區中。 At the same time, since the transport vehicle remains running, the gas barrier structure must be spaced a certain distance from the bottom of the transport vehicle. From the inside of the raw material layer, the biased exhaust gas can flow into the exhaust gas circulation area along the top surface of the gas barrier structure. In a modification of the present invention, in order to prohibit or prevent the bias flow, the gas blocking structure has fins. The fins extend in the direction of travel of the transport vehicle. Use this tab knot Structure, the exhaust gas flow along the gas barrier structure and on the gas barrier structure will not be biased, but is divided into the exhaust gas discharge area and the exhaust gas circulation area substantially equally.

在對第9圖之(b)與(c)之間進行之比較中,可看出,具有氣體阻擋本體及翼片之氣體阻擋結構相較僅具有氣體阻擋本體之氣體阻擋結構更有效地抑制廢氣回流。亦即,根據本發明改型之氣體阻擋結構可更包含翼片,以更有效地抑制廢氣回流。如此一來,發明人確認,本發明之實施例及其改型有效地抑制廢氣回流。另一方面,為查看本發明本實施例之氣體阻擋本體及本實施例改型之翼片的至少其中之一是否禁止廢氣回流,對氣體阻擋本體及翼片處之廢氣量之變化進行量測。 In the comparison between (b) and (c) of Fig. 9, it can be seen that the gas barrier structure with the gas barrier body and the fin is more effective than the gas barrier structure with the gas barrier body only Exhaust gas flows back. That is, the modified gas barrier structure according to the present invention may further include fins to more effectively suppress exhaust gas from flowing back. As such, the inventors have confirmed that the embodiments of the present invention and their modifications effectively suppress exhaust gas backflow. On the other hand, in order to check whether at least one of the gas-blocking body of the present embodiment of the present invention and the modified fins of this embodiment prohibits the backflow of exhaust gas, the change in the amount of exhaust gas at the gas-blocking body and the fins is measured. .

根據比較例、本發明實施例、及本發明實施例之改型,第10圖顯示對氣體抽吸陣列內部之廢氣流進行之一降階建模實驗之結果之照片。第10圖之(a)顯示根據比較例,降階建模實驗之一結果之一照片。第10圖之(b)顯示根據本發明實施例,降階建模實驗之一結果之一照片。第10圖之(c)顯示根據本發明之第一改型,對用於具有一氣體阻擋本體及一單個翼片之一氣體阻擋結構進行之降階建模實驗之一結果之一照片。 According to the comparative example, the embodiment of the present invention, and the modification of the embodiment of the present invention, FIG. 10 shows a photo of the result of performing a reduced-order modeling experiment on the exhaust gas flow inside the gas suction array. (A) of FIG. 10 shows a photograph of one of the results of the reduced-order modeling experiment according to the comparative example. Fig. 10 (b) shows a photo of one of the results of a reduced-order modeling experiment according to an embodiment of the present invention. Fig. 10 (c) shows a photo of one of the results of a model reduction experiment performed on a gas barrier structure having a gas barrier body and a single fin according to a first modification of the present invention.

在此實驗中,當一風箱之一上部端之一橫截面積被設定成1時,翼片之延伸長度被設定成2/3。對於降階建模實驗,製備對與比較例、本發明實施例、及本發明實施例改型中之每一者對應之每一氣體抽吸陣列之一內部結構進行建模之一幾何降階建模模型。使用燒結機之燒結條件對每一降階模型進行每一實驗。 In this experiment, when the cross-sectional area of an upper end of an air box is set to 1, the extension length of the fin is set to 2/3. For the reduced-order modeling experiment, a geometric reduced-order model is prepared to model an internal structure of each gas suction array corresponding to each of the comparative example, the embodiment of the present invention, and the modifications of the embodiment of the present invention. Modeling model. Each experiment was performed on each reduced-order model using the sintering conditions of the sintering machine.

第11圖中顯示降階建模實驗之結果。第11圖顯示一表,其指示根據比較例、本發明實施例、及本發明實施例改型,對氣體抽吸陣列中之廢氣流進行之降階建模實驗之結果。就此而言,在第11圖中,比較例對應於 根據本發明比較例之降階建模實驗之結果,實施例1對應於根據本發明實施例之降階建模實驗之結果,而實施例2對應於根據本發明第一改型對包含氣體阻擋本體及單個翼片之阻擋結構進行之降階建模實驗之結果。 Figure 11 shows the results of the reduced-order modeling experiment. FIG. 11 shows a table indicating the results of a reduced-order modeling experiment performed on the exhaust gas flow in the gas suction array according to the comparative example, the embodiment of the present invention, and the modification of the embodiment of the present invention. In this regard, in Figure 11, the comparative example corresponds to According to the results of the reduced-order modeling experiment of the comparative example of the present invention, Example 1 corresponds to the results of the reduced-order modeling experiment according to the embodiment of the present invention, and Example 2 corresponds to the gas barrier containing gas barrier according to the first modification of the present invention. The results of the reduced-order modeling experiments on the barrier structure of the body and the single fin.

參照此等結果,可看出,關於具有氣體阻擋本體之實施例1,相較於比較例,廢氣流率得以可靠地維持。可看出,關於更包含翼片之實施例2,相較於比較例,廢氣循環區之廢氣流率提高12%,且一總流率提高11%。 換言之,僅包含氣體阻擋本體之氣體阻擋結構可在抑制流干擾的同時維持廢氣之流率。更包含翼片之氣體阻擋結構可同時地抑制流干擾並提高廢氣流率。 With reference to these results, it can be seen that, in Example 1 having a gas-blocking body, the exhaust gas flow rate can be reliably maintained compared to the comparative example. It can be seen that, regarding Example 2 which further includes fins, compared with the comparative example, the exhaust gas flow rate in the exhaust gas circulation region is increased by 12%, and the total flow rate is increased by 11%. In other words, the gas blocking structure including only the gas blocking body can maintain the flow rate of the exhaust gas while suppressing the flow interference. A gas barrier structure including fins can simultaneously suppress flow interference and improve exhaust gas flow rate.

為何翼片的存在能夠提高總廢氣流率以及至廢氣循環區之廢氣流率之原因係如下。由於廢氣排放區與廢氣循環區之間的流干擾被翼片有效地抑制或防止,因而可自具有相對高通氣阻力之廢氣循環區中之原材料層充分地吸取廢氣。 The reason why the existence of the fins can increase the total exhaust gas flow rate and the exhaust gas flow rate to the exhaust gas circulation region is as follows. Since the flow interference between the exhaust gas emission area and the exhaust gas circulation area is effectively suppressed or prevented by the fins, the exhaust gas can be sufficiently sucked from the raw material layer in the exhaust gas circulation area having a relatively high ventilation resistance.

具體而言,廢氣循環區中之負壓不受廢氣排放區中之負壓干擾。因此,在具有較高通氣阻力之廢氣循環區中,廢氣循環區中之負壓作用於原材料層之全部或大部分上。此使得廢氣循環區中之廢氣流率能夠提高,且同時使得在廢氣排放區中廢氣能夠被順利地吸取。此可提高整體廢氣流率。 Specifically, the negative pressure in the exhaust gas circulation area is not disturbed by the negative pressure in the exhaust gas discharge area. Therefore, in the exhaust gas circulation area with a higher ventilation resistance, the negative pressure in the exhaust gas circulation area acts on all or most of the raw material layer. This enables the exhaust gas flow rate in the exhaust gas circulation area to be increased, and at the same time enables the exhaust gas to be smoothly sucked in the exhaust gas discharge area. This can increase the overall exhaust gas flow rate.

在下文中,闡述一種使用根據本發明實施例之廢氣處理設備來處理廢氣之方法。大體上,該廢氣處理方法可包含:將一原材料裝載至一運送車中,且在使該運送車沿複數個處理區移動之同時對該運送車中之該材料進行熱處理;使用一氣體抽吸陣列將該運送車之一內部向下抽吸,其中該氣體抽吸陣列在該運送車之一移動方向上延伸且設置於該運送車下方, 其中該氣體抽吸陣列具有彼此分離的一廢氣循環區及一廢氣排放區;以及抑制氣體自該廢氣循環區及該廢氣排放區中之一較低負壓區流動至該氣體抽吸陣列與該運送車之間的一空間中。 In the following, a method for treating exhaust gas using an exhaust gas treatment apparatus according to an embodiment of the present invention is explained.

The gas suction array is disposed below the bottom of the transport cart and extends in the direction of the transport cart. The gas suction array is divided into an exhaust gas circulation area and an exhaust gas discharge area. The gas suction array may be a gas suction array as described above in the exhaust gas treatment apparatus according to the embodiment of the present invention. With this gas suction, the combustion cavity can be moved from the upper end to the lower part of the raw material layer, so that the raw material is completely sintered.

在對運送車之內部進行抽吸的同時,可進行回流抑制操作。 回流抑制操作可包含抑制氣體自廢氣循環區及一廢氣排放區中之一較低負壓區經由氣體抽吸陣列與運送車之間的間隔流動至廢氣循環區及一廢氣排放區中之一較高負壓區。就此而言,抑制氣體自較低負壓區流動至較高負壓區可包含使用以上所定義之氣體阻擋結構,該氣體阻擋結構設置於廢氣循環區與廢氣排放區之間的邊界處。 While suctioning the inside of the transport cart, it can perform backflow suppression operation.

In this regard, inhibiting the flow of gas from the lower negative pressure region to the higher negative pressure region may include using a gas barrier structure as defined above, which is disposed at a boundary between the exhaust gas circulation region and the exhaust gas emission region.

如上所述,在藉由使用氣體阻擋結構抑制廢氣回流之操作中,可使用自氣體阻擋結構之翼片向上突出之至少一個凸肋來更有效地抑制廢氣流在翼片之一上表面上流動。 As described above, in the operation of suppressing the backflow of exhaust gas by using the gas blocking structure, at least one rib protruding upward from the fin of the gas blocking structure may be used to more effectively suppress the exhaust gas flow on the upper surface of one of the fins .

另一方面,以上已數次闡述了使用根據實施例之氣體阻擋結構以及使用根據實施例改型之翼片及凸肋來抑制或防止廢氣回流。因此,為避免贅述,將不再對此進行說明。 On the other hand, the use of the gas blocking structure according to the embodiment and the use of the fins and the ribs modified according to the embodiment have been explained several times to suppress or prevent the exhaust gas from flowing back. Therefore, to avoid repetition, this will not be described again.

在輸送路徑之末端處將已製成之燒結礦石卸出至壓碎單元。 藉由壓碎單元將所卸出之燒結礦石壓碎成一預定粒徑。藉由一篩分機對被壓碎之礦石進行篩分。視粒徑而定,被篩分之礦石可被饋送至一鼓風爐製程(其係為一後續製程),或另一選擇為,可用作上部燒結礦石,或另一選擇為,可被視為回爐礦石以重新用作原材料。 The finished sintered ore is discharged to the crushing unit at the end of the conveying path.
