Description

A kind of hydrogen manufacturing conversion furnace
Technical field
The utility model relates to conversion of natural gas device for producing hydrogen, particularly a kind of hydrogen manufacturing conversion furnace.
Background technology
In conversion of natural gas device for producing hydrogen, (be reforming gas, composition is H to natural gas steam reformer reforming gas exit gas 2, CO 2, CO etc.), temperature is up to 800 DEG C-850 DEG C, pressure position 2.0Mpa left and right.In the raw Hanzhong of industry, conventionally utilize this high temperature and high pressure gas to heat the required saturation steam of whole device.
For effectively utilizing heat energy, conventionally be preheating to 400 DEG C-600 DEG C by reacting desired raw material gas (natural gas hydrogen production plant unstripped gas is the mixed gas that Sweet natural gas and steam mix by a certain percentage) at natural gas reformer convection zone, react entering in reformer tube.
In general industry is produced, the interchanger between gas adopts tube and shell heat exchanger more, and as U-shaped tube heat-exchanger, fixed tube-sheet heat exchanger and floating head heat exchanger etc., this class interchanger is connected heat transfer tube with tube sheet, then by the connected structure formation of housing.
But in actual use, U-shaped tube heat-exchanger is due to the bent tube section curvature difference of U-shaped pipe, and heat transfer tube length is inconsistent, thereby material skewness, heat transfer tube, because of after seepage blocks, will cause the loss of heat transfer area.The complicated structure of floating head heat exchanger, and floating end tegillum time cannot know leak case in operation, therefore pays particular attention to when mounted its sealing.Fixed tube-sheet heat exchanger, under the operating mode of High Temperature High Pressure, for avoiding the difference of thermal expansion excessive, must arrange expansion joint on interchanger, and this will increase the cost of whole equipment and weight, occupation of land.
As mentioned above, existing structure all has weak point.
Utility model content
The purpose of this utility model is to provide a kind of hydrogen manufacturing conversion furnace, and it mainly solves the existing technical problem of above-mentioned prior art, and it can carry out abundant preheating to reaction desired raw material gas, and improves transformation efficiency, the compact construction of equipment, rationally.
For solving the problems of the technologies described above, the utility model is achieved in that
A kind of hydrogen manufacturing conversion furnace, it comprises the reformer tube of installing in body of heater and body of heater and has the burner of lighter for ignition; It is characterized in that: this reformer tube top connects unstripped gas entrance, transformation of synthetic gas outlet and preheating exhanst gas outlet, and in the body of this reformer tube, epimere is provided with main evaporator, and this main evaporator is outside equipped with the spiral heat exchange tube that upper end is communicated with unstripped gas entrance; This spiral heat exchange tube lower end is connected to the auxiliary evaporator of hypomere in the body that is arranged on reformer tube; In the body of the reformer tube between this auxiliary evaporator and main evaporator, be filled with conversion catalyst.
Described hydrogen manufacturing conversion furnace, is characterized in that: 4 reformer tubes that distribute around this burner, have respectively fuel high pressure gas inlet, fuel low pressure gas entrance, gas inlet and waste gas outlet on this burner.
Described hydrogen manufacturing conversion furnace, is characterized in that: the reformer tube in this body of heater also arranges thermal radiation cylinder.
Described hydrogen manufacturing conversion furnace, is characterized in that: this body of heater has furnace outer wall and is arranged on the furnace lining in furnace outer wall.
The utility model is compared with existing conventional art, tool has the following advantages: use the utility model, the mixing raw material gas of water vapour and Sweet natural gas enters the spiral tube exchanger in reformer tube, the synthetic vapour heat exchange of returning on backward with conversion, unstripped gas after heat exchange enters auxiliary evaporator by downward pipeline, then upwards return to enter in the conversion tube body that catalyzer is housed and carry out pyroreaction, and with the heat that absorbs to tube wall, transform the synthetic vapour generating and go out by the flange ozzle at boiler tube top.Its heat exchange efficiency is high, and energy utilization is abundant.
Brief description of the drawings

Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation of reformer tube in the utility model.
Embodiment
Refer to Fig. 1-3, the utility model discloses a kind of hydrogen manufacturing conversion furnace.As shown in the figure: it comprises the reformer tube 1 of installing in body of heater and body of heater and the burner 2 with lighter for ignition 21.This reformer tube 1 top connects unstripped gas entrance 11, transformation of synthetic gas outlet 12 and preheating exhanst gas outlet 13, in the body of this reformer tube 1, epimere is provided with main evaporator 14, and this main evaporator 14 is outside equipped with the spiral heat exchange tube 15 that upper end is communicated with unstripped gas entrance 11; These spiral heat exchange tube 15 lower ends are connected to the auxiliary evaporator 16 of hypomere in the body that is arranged on reformer tube 1; In the body of the reformer tube 1 between this auxiliary evaporator 16 and main evaporator 14, be filled with conversion catalyst 17.
When the utility model uses, because conversion reaction is to start 400 DEG C-600 DEG C in the situation that to occur, therefore the mixture of water vapour and methane needs preheating entering before the reformer tube 1 that catalyzer 17 is housed, so being set on reformer tube 1 top, spiral heat exchange tube 15 is used for preheating material gas, unstripped gas after heat exchange enters main evaporator 14, then enter auxiliary evaporator 16 by downward pipeline, go out auxiliary evaporator 16 and return on backward to enter and in the body that catalyzer 17 is housed, carry out pyroreaction, and with the heat that absorbs to tube wall.React temperature required and reach 800 DEG C-1000 DEG C, along with the raising depth of conversion of temperature also improves, transform the synthetic vapour generating and go out by the transformation of synthetic gas outlet 12 at body top.The outer high-temperature flue gas of reformer tube 1 through with reformer tube 1 heat exchange after discharge after again by furnace roof and combustion air heat exchange.
As a kind of preferred structure, 4 reformer tubes 1 that distribute around this burner 2, have respectively fuel high pressure gas inlet 22, fuel low pressure gas entrance 23, gas inlet 24 and waste gas outlet 25 on this burner 2.
As a kind of preferred structure, the reformer tube 1 in this body of heater also arranges thermal radiation cylinder 3, and the combustion flame of burner 2 is direct heating reformer tube 1 not, but by combustion flame heat hot radiative cylinder 3, thermal radiation cylinder 3 is to reformer tube release of radiation warm
