詳細地說，當該車輛發動後，其引擎排放的廢氣及廢熱會經由該進氣口211進入該加熱腔2，此時，外在的該反應空氣也被引入該進氣導管42中，由於該進氣導管42的該纏繞段421是以線圈方式纏繞著該反應腔體31，可增加該反應空氣的傳輸路徑並增進熱交換的面積，而可利用位在該加熱腔2中的廢熱藉由熱交換的方式有效的加熱該纏繞段421中的該反應空氣，接著，經加熱的該反應空氣透過該輸氣段423輸入至該反應空間310中，於此同時，一併將該供油單元102的油料由該進油導管41輸入至該反應空間310中，此時，將呈高溫的該反應空氣與油料於該反應空間310中混合部分氣化使其達到反應溫度(＞650℃)，並透過該觸媒單元35進行觸媒催化反應，從而產生富氫合成氣體，而經由該產物導管43輸出。前述藉由部分氣化催化產生的富氫合成氣體的方式與該供油單元102供應的油料及反應空氣的混合比例，決定於油料的碳莫耳數及反應空氣的氧莫耳數，因此，會視使用的油料或是氣體的含氧量不同而有所差異，由於此氧/碳莫耳比值的控制範圍比例為本技術領域所周知，故於此不再多加贅述。In detail, when the vehicle is started, exhaust gas and waste heat discharged from the engine enter the heating chamber 2 via the air inlet 211, and at this time, the external reaction air is also introduced into the intake duct 42 due to The winding section 421 of the intake duct 42 is wound around the reaction chamber 31 in a coil manner, which can increase the transmission path of the reaction air and increase the area of heat exchange, and can utilize the waste heat in the heating chamber 2 The reaction air in the winding section 421 is effectively heated by heat exchange, and then the heated reaction air is introduced into the reaction space 310 through the gas delivery section 423, and at the same time, the oil is supplied. The oil of the unit 102 is input into the reaction space 310 by the oil inlet conduit 41. At this time, the reaction air at a high temperature and the oil are partially mixed in the reaction space 310 to be vaporized to reach a reaction temperature (>650 ° C). The catalyst-catalyzed reaction is carried out through the catalyst unit 35 to generate a hydrogen-rich synthesis gas, which is output via the product conduit 43. The mixing ratio of the hydrogen-rich synthesis gas generated by the partial gasification catalysis to the oil supply and the reaction air supplied by the oil supply unit 102 is determined by the number of carbon moles of the oil and the oxygen mole of the reaction air. Depending on the oxygen content of the oil or gas used, the ratio of the oxygen/carbon molar ratio control range is well known in the art, and therefore will not be further described herein.
此處要說明的是，該等持溫件36的目的是用以提高該觸媒單元35的反應溫度並增進池溫效果，然而，實際實施時，若該反應腔3的持溫效果較佳時，也可不需設置該等持溫件36，或是僅設置於該觸媒單元35的其中一側邊即可。此外，值得一提的是，本發明廢熱重組產氫裝置透過套管式的組裝設計而緊密地安裝於安裝於該排氣管101上，能避免該引擎所排放之廢氣的壓力損失，且本發明廢熱重組產氫裝置供該廢氣的空間流速是大於該引擎的最大排氣流量，因此，不會影響該引擎排氣背壓(back pressure)。It should be noted that the purpose of the temperature holding members 36 is to increase the reaction temperature of the catalyst unit 35 and improve the pool temperature effect. However, in actual implementation, if the temperature of the reaction chamber 3 is better. In this case, the temperature holding members 36 need not be provided, or only one side of the catalyst unit 35 may be disposed. In addition, it is worth mentioning that the waste heat recombination hydrogen production device of the present invention is closely installed on the exhaust pipe 101 through a casing type assembly design, thereby avoiding pressure loss of the exhaust gas discharged from the engine, and The waste heat recombination hydrogen producing device is provided for the space flow rate of the exhaust gas to be greater than the maximum exhaust gas flow rate of the engine, and therefore, does not affect the engine exhaust back pressure.
另外要特別說明的是，當發明的車輛為一般柴油引擎車輛，該供油單元102即為該車輛本身的油箱，該供油單元102所提供的油料則為柴油或含不同比例的生質燃油，而適用於壓燃引擎。此外，本發明廢熱重組產氫裝置的該產物導管43是可視需求的連接至不同裝置以產生不同功效，例如可連接至該車輛的該引擎、或可連接至該車輛的一廢氣後處理器103，或可連接至該車輛的一燃料電池輔助動力系統(圖未示)的其中至少一種。也就是說，該產物導管43也可同時分別連接至例如該引擎與該廢氣後處理器103，而將產出的富氫合成氣體導出利用，並不限於單一位置導出。In addition, it should be particularly noted that when the invented vehicle is a general diesel engine vehicle, the oil supply unit 102 is the fuel tank of the vehicle itself, and the oil supplied by the oil supply unit 102 is diesel or contains different proportions of biofuel. And for compression ignition engines. Furthermore, the product conduit 43 of the waste heat recombination hydrogen production unit of the present invention is optionally coupled to different devices to produce different efficiencies, such as the engine connectable to the vehicle, or an exhaust aftertreatment processor 103 connectable to the vehicle. Or at least one of a fuel cell assisted power system (not shown) connectable to the vehicle. That is, the product conduit 43 can also be coupled to, for example, the engine and the exhaust aftertreatment processor 103, respectively, to derive the utilized hydrogen-rich synthesis gas, and is not limited to a single location.
詳細地說，由於富氫合成氣體中的氫氣(H 2)具有火焰傳播速度快、可燃極限 (flammability limits)範圍廣，及熄滅直徑小的特性，而其中的一氧化碳(CO)能提高絕熱火焰溫度，因此，當該產物導管43是連接該車輛的該引擎，使該產物導管43輸出的富氫合成氣體於該引擎氣缸內進行摻燒時，能提供該引擎達到超稀薄(Ultra-lean)燃燒條件，進一步地提升該引擎燃燒效率，並降低油耗與污染排放。 In detail, since hydrogen (H 2 ) in the hydrogen-rich synthesis gas has a high flame propagation speed, a wide range of flammability limits, and a small extinction diameter, carbon monoxide (CO) therein can increase the adiabatic flame temperature. Therefore, when the product conduit 43 is the engine that connects the vehicle, the hydrogen-rich synthesis gas output from the product conduit 43 is blended in the engine cylinder to provide the engine to ultra-lean combustion. Conditions further improve the combustion efficiency of the engine and reduce fuel consumption and pollution emissions.
當該產物導管43是連接該車輛的該廢氣後處理器103時，該產物導管43輸出的富氫合成氣體能結合該廢氣後處理器103的再生技術，以提升排氣溫度，從而提高柴油碳微粒濾清器(diesel particulate filter，DPF)的再生效果，及提高選擇性觸媒還原(selective catalytic reduction，SCR)系統在冷起動與低溫情況的氮氧化物(NO x)的轉化效率，能有效控制排氣污染。 When the product conduit 43 is connected to the exhaust aftertreatment processor 103 of the vehicle, the hydrogen-rich synthesis gas output by the product conduit 43 can be combined with the regeneration technology of the exhaust aftertreatment processor 103 to raise the exhaust gas temperature, thereby increasing diesel carbon. The regeneration effect of diesel particulate filter (DPF) and the efficiency of selective oxidation reduction (SCR) system for nitrogen oxide (NO x ) conversion in cold start and low temperature conditions are effective. Control exhaust pollution.
當該產物導管43是連接該車輛的該燃料電池輔助動力系統(APU)時，該產物導管43輸出的富氫合成氣體能做為車載燃料電池輔助電力系統之反應氣體。When the product conduit 43 is the fuel cell auxiliary power system (APU) that is connected to the vehicle, the hydrogen-rich synthesis gas output by the product conduit 43 can be used as a reaction gas for the on-board fuel cell auxiliary power system.
配合參閱圖4，本發明廢熱重組產氫裝置的一第二實施例大致相同於該第一實施例，其不同處在於，該第二實施例之該廢熱重組產氫裝置還包含至少一個預熱器5(圖4中以兩個預熱器5為例說明)。該等預熱器5是穿過該加熱腔2與該反應腔3，並包括一位於該反應空間310中的加熱段51。其中，該等預熱器5位於該反應空間310的位置並沒有特別限制，只要能對該反應空間310提供熱源即可。較佳地，於本實施例中，其中一該加熱段51是位於該持溫件36與該進油孔32之間，而其中另一該加熱段51則是位於該等持溫件36之間而與該觸媒單元35直接接觸。藉由設置該預熱器5而將其加熱段51伸入該反應空間310中，可於引擎尚未起動或反應溫度不足時，主動提供反應所需熱源，從而提高輸出富氫合成氣體的流率的穩定性，並可讓該廢熱重組產氫裝置於該車輛引擎未發動的狀態下，也可主動合成富氫合成氣體。Referring to FIG. 4, a second embodiment of the waste heat recombination hydrogen producing apparatus of the present invention is substantially the same as the first embodiment, except that the waste heat recombination hydrogen producing apparatus of the second embodiment further comprises at least one preheating. The device 5 (illustrated by taking two preheaters 5 in FIG. 4 as an example). The preheater 5 passes through the heating chamber 2 and the reaction chamber 3 and includes a heating section 51 located in the reaction space 310. The position of the preheater 5 in the reaction space 310 is not particularly limited as long as the heat source can be provided to the reaction space 310. Preferably, in the embodiment, one of the heating segments 51 is located between the temperature holding member 36 and the oil inlet hole 32, and the other heating portion 51 is located at the temperature holding members 36. It is in direct contact with the catalyst unit 35. By providing the preheater 5, the heating section 51 is inserted into the reaction space 310, and the heat source required for the reaction can be actively provided when the engine is not started or the reaction temperature is insufficient, thereby increasing the flow rate of the hydrogen-rich synthesis gas. The stability and the waste heat recombination hydrogen production device can also actively synthesize a hydrogen-rich synthesis gas under the condition that the vehicle engine is not started.
綜上所述，本發明廢熱重組產氫裝置，直接裝設在該車輛的該廢氣排放口100，以利用引擎產生的廢熱作為熱量來源，以與進氣導管42進行熱交換，再配合車輛自有的供油單元102提供燃料，從而有效利用引擎的廢熱進行產氫反應，並能輔以該等持溫件36提高該觸媒單元35反應溫度以增進持溫效果；此外，藉由讓廢氣的空間流速大於該引擎的最大排氣流量，而不會影響該引擎排氣背壓；還可進一步設置該預熱器5於引擎尚未起動或該觸媒單元35溫度不足時，主動提供該觸媒單元35所需的熱源，故確實能達成本發明的目的。In summary, the waste heat recombination hydrogen production device of the present invention is directly installed in the exhaust gas discharge port 100 of the vehicle to utilize the waste heat generated by the engine as a heat source to exchange heat with the intake duct 42 and then cooperate with the vehicle.
