Present embodiment is an example with catalytic combustion evaporator required in the fuel cell hydrogen generating system.The fuel gas that is used to burn in the catalytic combustion evaporator of the present invention is a hydrogen, but its design flow is the mixture 86ml/min (water alcohol mol ratio is 1.2: 1) of unit catalytic combustion evaporator gasified methanol and water.
Flow process of the present invention is as follows: hydrogen enters horizontal distribution pipe 8 by inlet b and enters horizontal distribution pipe 7 again, the aperture that on distributor pipe 7, distributes, hydrogen evenly enters eight main combustion chamber 12c, and the purpose of doing like this is even in order to burn, and the 2nd, avoided the danger of hydrogen detonation; Air enters into distributing disc 9 by hole a, the aperture of on distributing disc 9, evenly arranging, air-flow is blown into eight main combustion chamber 12c in even mode, contact with the hydrogen that disperses and on catalyst surface, to carry out catalytic combustion (the present invention be called for the first time burn), major part among eight main combustion chamber 12c, temperature remains on about 350 ℃, and temperature can be regulated by the air capacity or the amounts of hydrogen that enter eight main combustion chamber 12c.Hydrogen and oxygen mixture enters end socket 3 after eight main combustion chamber 12c burnings, owing in the end socket 3 combustion catalyst is housed, unburned hydrogen further burns (the present invention is called burning for the second time), and the temperature at this place is generally about 450 ℃.Hydrogen and oxygen mixture is entering two of the left side combustion chamber 12a, 12b for the third time, further burning (the present invention is called burning for the third time) through burning back revolution for the second time.Gas further burning (the present invention is called the 4th burning) again in combustion chamber 11 of coming out by combustion chamber 12a, 12b for the third time, at this moment the fuel in the combustion chamber 12 is fallen by full consumption basically, then combustion tail gas enters bottom bulkhead 6 by rectangular opening 13, discharges outside by outlet d again.
Need the raw material (first alcohol and water) of gasification to enter the coil pipe 4 that is arranged on end socket 3 inside by inlet e earlier, the second-time burning air-flow of material liquid in coil pipe 4 and in the end socket 3 carries out heat exchange, with a feed vaporization part, temperature brought up to about 90 ℃.Outlet f by coil pipe 4 flows out through the raw material after the preheating, enter the feed distributor g of end socket 1 by feed distributor g rear end first aperture, raw material is the process redistribution in feed distributor g, evenly enter flush distillation chamber 14a (being first passage of left side of evaporation cavity 14) through remaining aperture, in the 14a of flush distillation chamber, the burning hot gas stream first time in raw material and the combustion chamber 12 carries out heat exchange, makes part water and most of methyl alcohol be vaporized.Then, raw material is in evaporation cavity 14 bottoms, the gap through between evaporation cavity 14 lower open mouths and upper plate, and turning back enters double evaporation-cooling chamber 14b (being eight parallel channels on the right side of evaporation cavity 14).The place of turning back in the bottom of evaporation cavity 14, the high-temp combustion tail gas that end socket 6 internal combustions burn down plays the effect of heating and insulation to the raw material of evaporation cavity 14 bottoms, has avoided raw material to be cooled in the bottom well and causes the hydrops phenomenon.Raw material evaporation cavity 14 bottoms turn back enter double evaporation-cooling chamber 14b after, in raw material and the combustion chamber 12 for the first time the thermal current of burning carried out sufficient heat exchange again.In the 14b of double evaporation-cooling chamber, utilize to rise film vaporization mode, raw material is entered by double evaporation-cooling chamber 14b bottom, discharges catalytic combustion evaporator by the outlet c on the end socket 2, and raw material has fully been gasified when reaching outlet c place, and temperature can reach 200-300 ℃.
The specification of the catalytic combustion evaporator body that manufactures and designs by above-mentioned design is: 100 * 100 * 130mm
3, the combustion catalyst amount of adding is about 250mL.In the experiment according to the flow process shown in Figure 2 operation that experimentizes, the combustion chamber of catalytic combustion evaporator inside and the uniformity of temperature profile of evaporation cavity (seeing Fig. 3, Fig. 4).Part of test results can see Table 1, and the present invention reaches designing requirement fully.
