Reforming catalyst is provided in cold fluid cavity, the entrance of first layer cold fluid cavity is connected to cold fluid inlet 23, finally
The outlet of layer cold fluid cavity is connected to cold fluid outlet 24, and thus methanol-water gaseous mixture is flowed into reformation through cold fluid inlet 23
In the cold fluid cavity of device 2, catalytic reforming reaction is carried out under the action of reforming catalyst, the hydrogen-rich product for reacting generation is final
It is flowed out by cold fluid outlet 24, is stored subsequently into hydrogen purification and hydrogen is carried out in purification reservoir 3.Every layer of hot fluid cavity
Entrance be connected to thermal fluid inlet 21, the outlet of every layer of hot fluid cavity is connected to hot fluid outlet ports 22, i.e., by hot-fluid
Body entrance 21 is passed through automobile hot exhaust gas as heat source, and automobile hot exhaust gas uniformly enters in each layer hot fluid cavity of reformer 2,
Reformer 2 is heated.The cold fluid cavity and hot fluid cavity are the structure of stratiform cavity, and the cold flow body cavity
Road and hot fluid cavity are arranged alternately in 2 interior-layer layer of reformer, and thus methanol-water gaseous mixture and automobile hot exhaust gas are in reformer 2
It is exchanged heat layer by layer, substantially increases the capacity usage ratio of automobile hot exhaust gas, secondly automobile hot exhaust gas is uniformly divided into several branch
It flowing into the hot fluid cavity of several layers parallel connection of reformer 2, the temperature thus heated in each hot fluid cavity is uniform,
Hot exhaust gas temperature after longer heat exchange distance is avoided successively to reduce, thus the problem of causing reforming reaction non-uniform temperature
If (hot fluid cavity is to connect layer by layer, then hot exhaust gas is from first layer hot fluid cavity, layer hot fluid cavity is flowed over to the end
The temperature of Cheng Zhong, hot exhaust gas successively reduce).Methanol-water gaseous mixture passes sequentially through the concatenated cold flow of several layers of reformer 2
Body cavity road, it is ensured that reforming reaction raw material has the sufficient residence time in reformer 2, keeps reforming reaction more abundant.Pass through this
The structure of invention flows in the concatenated cold fluid cavity of several layers of the methanol-water in a manner of intimate plug flow in reformer 2.It is right
According in Fig. 7, c → b route is glide path of the methanol-water gaseous mixture in the cold fluid cavity in reformer 2, and a → d route is
Glide path of the automobile hot exhaust gas in the hot fluid cavity in reformer 2.
Reformer 2 is internally provided with the structure of alternate cold fluid cavity and hot fluid cavity layer by layer, and reformer 2 can be adopted
It is by the first plate 25, the second plate 26 and to be set to the first plate 25 and the second plate with structure formed below: reformer 2
The rubber sheet gasket being sealed between piece 26 is successively formed by stacking, first plate 25, rubber sheet gasket and the second plate 26
Between be enclosed the stratiform cavity of sealing, rubber sheet gasket constitutes the side wall of layered cavity, so the thickness of stratiform cavity
The thickness of as rubber sheet gasket (can be respectively provided with adhesive glue on rubber sheet gasket two sides, make the first plate 25 and rubber by adhesive glue
It carries out between glue gasket and pasting sealing between second plate 26 and rubber sheet gasket).First plate, 25 front, rubber sheet gasket
And the stratiform cavity formed between 26 back side of the second plate is the cold fluid cavity, 25 back side of the first plate, rubber sheet gasket
And the stratiform cavity formed between 26 front of the second plate is the hot fluid cavity;It further include being used on the reformer 2
First reformation master of the reformation runner for being sequentially communicated each layer cold fluid cavity, the entrance for being connected to each layer hot fluid cavity
Runner and the second reformation sprue of the outlet for being connected to each layer hot fluid cavity.
The mode that runner, the first reformation sprue and the second reformation sprue are reformed in setting on reformer 2 may is that
Several pipelines are worn in the overall structure that the first plate 25, rubber sheet gasket and the second plate 26 are successively formed by stacking, are being worn
If pipeline on appropriate aperture, make that the several layers cold fluid cavity in reformer 2 is sequentially connected in series and hot fluid cavity is successively in parallel.
Such as: a pipeline passes perpendicularly through the overall structure of reformer 2, and the pipeline upper end opening and thermal fluid inlet 21 carry out pair
Connect, lower end of duct opening is blocked, the part that the pipeline is located in every layer of hot fluid cavity carries out appropriate aperture,
This pipeline is consequently formed above-mentioned first and reforms sprue.
On reformer 2 setting reform runner, first reform sprue and second reform sprue mode can also be with
Be: the quadrangle of the first plate 25 and the second plate 26 offers punching, and the pair of horns of the first plate 25 is symmetrical arranged a pair of the
One cold punching hole 25a and another diagonally it is respectively arranged with that the first heat rushes in hole 25b and the first heat goes out hole 25c, second plate
26 corresponding pair of horns are symmetrical arranged second cold punching hole 26a of a pair and corresponding another diagonal be respectively arranged with the second heat and rush in hole
26b and the second heat go out hole 26c;When first plate 25 and the second plate 26 successively overlap arrangement, first cold punching
Hole 25a and the second cold punching hole 26a be aligned and pass through rubber sheet gasket be enclosed for the methanol-water gaseous mixture that circulates reformation shunting
(reform the specific generation type of runner are as follows: the first cold punching hole 25a and the second cold punching hole 26a encloses shape by rubber sheet gasket in road
At tubular conduit, the side wall of tubular conduit be rubber sheet gasket and tubular conduit both ends open be respectively the first cold punching hole 25a and
Second cold punching hole 26a.In hot fluid luminal portion, the side of the tubular conduit is without aperture;In cold fluid cavity
When part, the appropriate aperture in the side of the tubular conduit, and when the entrance of the side openings of tubular conduit and cold fluid cavity connects
When logical, the upper end opening of tubular conduit is blocked;When the outlet of the side openings of tubular conduit and cold fluid cavity,
The lower ending opening of tubular conduit is blocked.Thus comparative diagram 1 and Fig. 7, methanol-water gaseous mixture are walked in reformer 2 in zigzag
To stay flow up).First heat rushes in hole 25b and the second heat rushes in hole 26b and is aligned and enclosed by rubber sheet gasket
It forms first for flowing into hot exhaust gas and reforms sprue, first heat goes out hole 25c and the second heat goes out hole 26c alignment simultaneously
The second reformation sprue for flowing out hot exhaust gas is enclosed by rubber sheet gasket.
Structure of the invention further includes catalyst support plate 4, and comparative diagram 4, the reforming catalyst is CuO-ZnO-Al2O3
