圖1為根據本案的一個實施例的燒結爐100的結構示意圖。如圖1所示，燒結爐100包括爐膛112，爐膛112包括相互流體連通的烘乾段101、燒結段103和冷卻段105，光伏裝置（圖中未示出）被輸送裝置（圖中未示出）輸送，從爐膛112的左端依次經過烘乾段101、燒結段103和冷卻段105後，從爐膛112的右端輸出燒結爐100，以完成燒結處理的程序。在烘乾段101中，光伏裝置印刷的漿料中有機物等能夠揮發。在燒結段103中，光伏裝置上的電極材料和矽加熱達到共晶溫度，矽原子以一定比例溶入到熔融狀態的電極材料中。在冷卻段105中，光伏裝置上的溶入電極材料中的矽原子重新以固態形式結晶出來，使得電極與矽之間形成歐姆接觸，從而得到太陽能電池。Figure 1 is a schematic structural diagram of a
爐膛112還包括氣體入口104和氣體出口102。爐膛112中的廢氣從氣體出口102中排出，並且乾淨氣體從氣體入口104輸入，以完成爐膛112中的氣體的循環，將爐膛112中的氣體壓力維持在一定範圍內。在本實施例中，由於光伏裝置印刷的漿料中的有機物在烘乾段101中揮發，因此可以將氣體入口104和氣體出口102設置在烘乾段101上。The
燒結爐100還包括焚燒裝置110和換熱裝置120。焚燒裝置110與氣體出口102流體連通，以接收從氣體出口102排出的爐膛112中的廢氣。從氣體出口102排出爐膛112的廢氣中主要包括有機物，經過焚燒裝置110加熱焚燒處理後能夠得到淨化處理氣體。在本實施例中，有機物經過焚燒處理後得到的淨化處理氣體主要成分為二氧化碳和水。The
換熱裝置120內部包括第一氣體通道121和第二氣體通道122，第一氣體通道121中的氣體和第二氣體通道122中的氣體能夠進行熱交換。焚燒裝置110與第二氣體通道122流體連通，以使得從焚燒裝置的出口管道211（參見圖2A和圖2B所示）排出的淨化處理氣體能夠在換熱裝置120的第二氣體通道122中流通。第一氣體通道121與氣體入口104流體連通，以流通將要輸入爐膛112的乾淨氣體。在本實施例中，乾淨氣體為外界環境中的空氣。外部環境中的空氣在驅動裝置131驅動下，流動經過第一氣體通道121後，從氣體入口104輸入爐膛112。The
在本實施例中，焚燒裝置110的出口處的氣體溫度大致為750℃左右，也就是說，第二氣體通道122中的氣體溫度大致為750℃左右。而被驅動裝置131驅動進入第一氣體通道121中的空氣溫度為室溫，大致為25℃左右。第一氣體通道121中的空氣與第二氣體通道122中的淨化處理氣體在換熱裝置120內部進行熱交換，使得空氣能夠被加熱後再輸入爐膛112中，並且淨化處理氣體能夠被冷卻。作為一個具體的示例，熱交換完成後的空氣和淨化處理氣體均為約400℃。熱交換完成後，淨化處理氣體可以與外界空氣混合降溫後，直接向外界排出，或者排出至工廠廢氣管道。而空氣可以直接從氣體入口104輸入爐膛112中。In this embodiment, the gas temperature at the outlet of the
作為一個更具體的示例，驅動裝置131可以為風機，通過控制風機的功率，可以調節空氣在第一氣體通道121中的流通速度，從而調節空氣被加熱的溫度。例如，在焚燒裝置110排出的淨化處理氣體流速一定的情況下，當空氣在第一氣體通道121中的流通速度較快時，熱交換完成後，被加熱的空氣的溫度較低。而當空氣在第一氣體通道121中的流通速度較慢時，熱交換完成後，被加熱的空氣的溫度也會較高。As a more specific example, the driving device 131 can be a fan. By controlling the power of the fan, the circulation speed of the air in the
本領域技藝人士可以理解的是，在一些其他的示例中，乾淨氣體也可以為惰性氣體，根據燒結爐100需要的氣體氛圍決定。Those skilled in the art can understand that in some other examples, the clean gas may also be an inert gas, which is determined according to the gas atmosphere required by the
一般的烘乾段101中需要設置一些加熱裝置對烘乾段101中的氣體進行加熱，以使得光伏裝置上印刷的漿料中的有機物能夠被烘乾。而通過設置換熱裝置120，焚燒裝置110處理後的淨化處理氣體的熱量能夠被充分利用，使得烘乾段101中的氣體能夠被加熱至預設溫度後，再輸入爐膛112的烘乾段101中。Generally, some heating devices need to be provided in the
在本實施例中，乾淨氣體的預設溫度大致為400℃，以滿足烘乾段101中氣體的溫度要求。在一些其他實施例中，也可以根據實際需要設置氣體入口104和氣體出口102的具體位置，並調節乾淨氣體的預設溫度。例如如果將氣體入口104設置在燒結段103上，預設溫度則需要滿足燒結段103中氣體的溫度要求。In this embodiment, the preset temperature of the clean gas is approximately 400°C to meet the temperature requirements of the gas in the
為了保證從氣體入口104輸入爐膛112中的乾淨氣體能夠達到需要的預設溫度，在一些實施例中，燒結爐100還可以包括加熱裝置130，加熱裝置130設置在換熱裝置120的第一氣體通道121和氣體入口104之間，用於對從換熱裝置120排出的被加熱的乾淨氣體進一步加熱，使得輸入爐膛112的氣體能夠達到相應的預設溫度。In order to ensure that the clean gas input into the
圖2A和圖2B圖示燒結爐100的烘乾段101的具體結構，其中圖2A為烘乾段101的立體結構圖，圖2B為烘乾段101的分解圖。為了清楚的顯示烘乾段101的結構，圖2A和圖2B中省去了燒結爐100的燒結段103、冷卻段105和燒結爐100的外殼，並且圖2B中省去了風機231和部分管道。如圖2所示，烘乾段101具有長度方向L，光伏裝置從烘乾段101的左端的入口271進入烘乾段101，沿著長度方向L向右輸送。焚燒裝置110設置在烘乾段101的頂部上方，並且與烘乾段101的內部通過烘乾段101的頂部的氣體出口202流體連通。焚燒裝置110具有出口管道211，從烘乾段101排出的廢氣經過焚燒裝置110進行的加熱焚燒處理後，從出口管道211排出淨化處理氣體。Figures 2A and 2B illustrate the specific structure of the
換熱裝置120設置在焚燒裝置110上方，其底部具有淨化處理氣體入口236，相對的頂部具有淨化處理氣體出口213，淨化處理氣體入口236和淨化處理氣體出口213通過換熱裝置120內部的第二氣體通道422（參見圖4B和圖4C所示）流體連通。淨化處理氣體入口236與焚燒裝置110的出口管道211流體連通，淨化處理氣體出口213通過另外的氣體冷卻裝置（圖中未示出）連接至工廠排氣管道。The
換熱裝置120的相對的前後兩側設有乾淨氣體入口233和乾淨氣體出口232，乾淨氣體入口233和乾淨氣體出口232通過換熱裝置120內部的第一氣體通道421（參見圖4B和圖4C所示）流體連通。乾淨氣體入口233與風機231的出風端235流體連通，風機231的進風端234與外界空氣連通。乾淨氣體出口232與烘乾段101上的氣體入口204通過管道237流體連通。在本實施例中，氣體入口204為兩個，連接至管道237的管道272和管道273分別從兩個氣體入口204處伸入烘乾段101內部，並分別向烘乾段101在長度方向L上的兩端方向延伸。加熱裝置230設置在管道237上。A
由此，從烘乾段101的氣體出口202排出的廢氣經過焚燒裝置110加熱焚燒處理為淨化處理氣體後，從出口管道211進入換熱裝置120的淨化處理氣體入口236，流經第二氣體通道422（參見圖4B和圖4C所示）後，再從淨化處理氣體出口213排出。外界空氣在風機231的驅動下從進風端234流向出風端235，然後從乾淨氣體入口233進入換熱裝置120，流經第一氣體通道421（參見圖4B和圖4C所示）後，從乾淨氣體出口232排出至管道237，再沿著管道272和管道273從兩個氣體入口204進入烘乾段101，並在烘乾段101中向烘乾段101的長度方向L的兩端流動。流經第一氣體通道421的空氣和流經第二氣體通道422的淨化處理氣體能夠在換熱裝置120中進行熱交換，以加熱空氣，並且冷卻淨化處理氣體。Therefore, after the exhaust gas discharged from the

換熱裝置120還包括一對管板347、前箱體342（即第二箱體）和後箱體341（即第一箱體）。一對管板347分別設置在殼體328的前後兩側，用於在前後方向上封閉殼體328並支撐殼體328內的換熱管329。前箱體342和後箱體341分別設置在一對管板347的外側。前箱體342和後箱體341為中空的方箱形狀，前箱體342設置在殼體328的前側，後箱體341設置在殼體328的後側。乾淨氣體入口233設置在後箱體341上並與後箱體341內部流體連通，乾淨氣體出口232設置在前箱體342上並與前箱體342內部流體連通。The
圖4A-圖4C圖示換熱裝置120的內部結構，其中圖4A為換熱裝置120的俯視圖，圖4B為圖4A的換熱裝置120沿A-A線的剖視圖，用於示出第一氣體通道421。圖4C為圖4A的換熱裝置120沿B-B線的剖視圖，用於示出第二氣體通道422。如圖4A-4C所示，換熱裝置120的殼體328內部具有換熱容腔440，換熱管329設置在換熱容腔440中。在本實施例中，一對管板347之間的殼體328內部形成換熱容腔440。換熱管329的長度方向上的兩端支撐在管板347上，並通過管板347與前箱體342和後箱體341流體連通。換熱管329內部用於流通乾淨氣體。前箱體342、後箱體341和換熱管329的內部共同形成第一氣體通道421。由此，外界空氣從乾淨氣體入口233經過後箱體341進入換熱裝置120的第一氣體通道421，在第一氣體通道421中與第二氣體通道422中的淨化處理氣體進行熱交換後，再經過前箱體342從乾淨氣體出口232排出。4A-4C illustrate the internal structure of the
換熱裝置120還包括數個分程隔板445，分程隔板445橫向地設置在前箱體342和後箱體341中，以將前箱體342和後箱體341分別隔離為數個區域。由此，換熱管329能夠具有多個管程，以增加空氣在第一氣體通道421中的流動距離，從而提高換熱效率。在本實施例中，前箱體342和後箱體341中各自設有兩個分程隔板445，以使得換熱管329具有五個管程。在其他實施例中，可以設置其他數量的分程隔板445，以使得換熱管329具有更多或更少的管程。The
換熱管329外部的換熱容腔440用於形成第二氣體通道422。淨化處理氣體從淨化處理氣體入口236進入第二氣體通道422後，向上流動以在第二氣體通道422中與第一氣體通道421中的空氣進行熱交換，然後從淨化處理氣體出口213排出。在本實施例中，換熱管329外部的淨化處理氣體和換熱管329內部的空氣通過換熱管329的管壁進行熱交換。換熱管329成排間隔地設置，並且相鄰兩排的換熱管329錯開佈置。也就是說，換熱管329大致佈置為三角形陣列，以使得淨化處理氣體能夠從相鄰的換熱管329的間隙中流過，並且淨化處理氣體需要流經每一排換熱管329，從而能夠提高淨化處理氣體的換熱效率。The
在本實施例中，第一氣體通道421中的空氣和第二氣體通道422中的淨化處理氣體沿著不同的方向流動以進行熱交換，能夠提高氣體和氣體之間的換熱效率。並且通過設置分程隔板445，能夠使第一氣體通道421中的空氣具有更長的流動路徑，通過設置換熱管329的佈置方式，能夠使第二氣體通道422中的淨化處理氣體具有更加曲折的流動路徑，從而使得空氣和淨化處理氣體能夠更加充分地進行熱交換。In this embodiment, the air in the
本領域技藝人士可以理解的是，換熱裝置也可以為其他結構的氣-氣換熱器，能夠使第一氣體通道中的氣體能夠與第二氣體通道中的氣體在換熱裝置中進行充分地熱交換即可。Those skilled in the art can understand that the heat exchange device can also be a gas-gas heat exchanger with other structures, which can enable the gas in the first gas channel to fully interact with the gas in the second gas channel in the heat exchange device. Just exchange geothermal heat.
在現有的一些燒結爐中，一方面向爐膛中輸入的乾淨氣體的溫度一般是室溫，然後通過設置在爐膛中的加熱元件對爐膛中的氣體進行加熱，以使得爐膛中的氣體達到一定的溫度，從而對光伏裝置進行需要的處理。另一方面，從焚燒裝置排出的氣體溫度較高，需要與低溫氣體混合後才能向外排放。In some existing sintering furnaces, on the one hand, the temperature of the clean gas input into the furnace is generally room temperature, and then the gas in the furnace is heated by the heating element provided in the furnace, so that the gas in the furnace reaches a certain temperature. temperature to perform the required treatment on the photovoltaic device. On the other hand, the gas discharged from the incineration device has a higher temperature and needs to be mixed with low-temperature gas before it can be discharged to the outside.
本案的燒結爐通過設置換熱裝置，利用從焚燒裝置排出的高溫氣體來加熱乾淨氣體，使得乾淨氣體在輸入爐膛前，就能夠達到預設溫度，從而可以減少爐膛中需要的加熱元件的數量，並且充分利用了焚燒裝置排出的高溫氣體的餘熱來節省能耗。並且本案的換熱裝置結構簡單，氣體和氣體之間換熱效率高，通過控制風機的功率基本上就能使空氣被加熱到需要的溫度。此外，本案的燒結爐可以在現有的燒結爐基礎上進行改造，新增換熱裝置等部件即可，改造成本低。The sintering furnace in this case is equipped with a heat exchange device and uses the high-temperature gas discharged from the incineration device to heat the clean gas, so that the clean gas can reach the preset temperature before being input into the furnace, thereby reducing the number of heating elements required in the furnace. And it makes full use of the waste heat of high-temperature gas discharged from the incineration device to save energy consumption. Moreover, the heat exchange device in this case has a simple structure and high heat exchange efficiency between gas and gas. By controlling the power of the fan, the air can basically be heated to the required temperature. In addition, the sintering furnace in this case can be modified on the basis of the existing sintering furnace by adding heat exchange devices and other components, and the modification cost is low.
