For achieving the above object, the utility model is implemented according to following technical scheme:
A kind of conversion gas, the efficient combination exchanger of semi-water gas, comprise the first tube and shell heat exchanger and the second tube and shell heat exchanger, bobbin carriage in the middle of also comprising, bobbin carriage both sides in the middle of described the first tube and shell heat exchanger and the second tube and shell heat exchanger are fixedly installed on, the first tube and shell heat exchanger, the second tube and shell heat exchanger and middle bobbin carriage bottom arrange skirt and fix, described the first tube and shell heat exchanger, middle bobbin carriage and the mutual UNICOM of the second tube and shell heat exchanger, middle bobbin carriage upper end arranges manhole.
As preferably, described the first tube and shell heat exchanger is comprised of the first bobbin carriage, the first heat transfer tube, the first rod baffle, the first cylindrical shell and First Heat Exchanger tube sheet, described the first cylindrical shell bottom arranges the inlet mouth of water the first conversion gas, the first cylindrical shell top arranges the air outlet of the first conversion gas, the first bobbin carriage top arranges the inlet mouth of semi-water gas, and the first bobbin carriage sidewall arranges sewage draining exit; The second tube and shell heat exchanger is comprised of the second bobbin carriage, the second heat transfer tube, the second rod baffle, the second cylindrical shell and the second heat exchanger tube sheet, described the second cylindrical shell bottom arranges the outlet of the second conversion gas, the second cylindrical shell top arranges the inlet mouth of the second conversion gas, and the sidewall of the second bobbin carriage arranges semi-water gas final outlet.
Compared with prior art, the utility model is optimized to greatest extent, simplified apparatus structure, reduces cost of manufacture; At utmost reduce the length of process pipe, reduce power, thermodynamic loss; Improvement traverse baffle is rod baffle, not affecting under the prerequisite of baffling effect, supporting role, at utmost reduces medium flowing resistance, improves heat exchange efficiency; Increase substantially utilization of area space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described, in illustrative examples and the explanation of this utility model, is used for explaining the utility model, but not as to restriction of the present utility model.
Conversion gas as shown in Figure 1, the efficient combination exchanger of semi-water gas, comprise the first tube and shell heat exchanger and the second tube and shell heat exchanger, bobbin carriage 8 in the middle of also comprising, bobbin carriage 8 both sides in the middle of described the first tube and shell heat exchanger and the second tube and shell heat exchanger are fixedly installed on, it is fixing that the first tube and shell heat exchanger, the second tube and shell heat exchanger and middle bobbin carriage 8 bottoms arrange skirt 15, described the first tube and shell heat exchanger, middle bobbin carriage 8 and the mutual UNICOM of the second tube and shell heat exchanger, middle bobbin carriage 8 upper ends arrange manhole 17.
As preferably, described the first tube and shell heat exchanger is comprised of the first bobbin carriage 14, the first heat transfer tube 13, the first rod baffle 12, the first cylindrical shell 11 and First Heat Exchanger tube sheet 9, described the first cylindrical shell 11 bottoms arrange the inlet mouth 10 of water the first conversion gas, the first cylindrical shell 11 tops arrange the air outlet 18 of the first conversion gas, inlet mouth 19, the first bobbin carriage 14 sidewalls that the first bobbin carriage 14 tops arrange semi-water gas arrange sewage draining exit 20; The second tube and shell heat exchanger is comprised of the second bobbin carriage 2, the second heat transfer tube 5, the second rod baffle 6, the second cylindrical shell 4 and the second heat exchanger tube sheet 3, described the second cylindrical shell 4 bottoms arrange the outlet 7 of the second conversion gas, the sidewall that the second cylindrical shell 4 tops arrange inlet mouth 16, the second bobbin carriages 2 of the second conversion gas arranges semi-water gas final outlet 1.
Middle temperature transformation gas out of hydrolysis stove enters the second heat exchanger tube pass by the inlet mouth 10 of the first conversion gas, from the air outlet 18 of the first conversion gas out process to semi-water gas preheating; The inlet mouth 16 of the second conversion gas of the high temperature shift gas of coming from last process enters First Heat Exchanger shell side, out enters leave from office equipment, to semi-water gas second-heating from the outlet 7 of the second conversion gas.Semi-water gas enters from the inlet mouth 19 of semi-water gas, from semi-water gas final outlet 1, out enter conversion equipment, after second-heating, semi-water gas approaches temperature of reaction and enters conversion equipment and react, and enters Xia Dao workshop section recycling after the utilization of high temperature shift gas.In situation, high, middle temperature transformation gas to semi-water gas heating, is fully used under differing temps, enters Xia Dao workshop section recycling in the situation that pressure drop is less like this.In process, the mobile distance of semi-water gas is short, and thermosteresis is little, and two kinds of conversion gas heat utilization efficiencies are high, and the little pressure drop of resistance is low, and enters smoothly Xia Dao workshop section recycling.The invention of this structure is simple and practical, and cost is low.
