The present invention relates to a plate-type reformer, with a low temperature absorbing reaction plate and a preheating guide plate arranged in a mirror symmetry centering on a high temperature exothermic reaction plate and dispersing and supplying fluid to each plate to reduce the pressure loss of the fluid, and It relates to a plate-type reformer to improve the thermal efficiency by configuring the temperature to go higher.

In general, the reforming reaction may be a reaction for producing hydrogen, which is a fuel used in fuel cells for automobiles, but may be classified into various types depending on the type of catalyst and the fluid reacting with each catalyst. It is widely used in many fields such as petrochemical process.

In addition, the reforming reaction may be classified into an exothermic reforming reaction that releases heat as opposed to an endothermic reforming reaction requiring heat (energy) during the reaction.

A reformer that causes such a reforming reaction is used to manufacture an endothermic reforming reaction or an exothermic reforming reaction in various sizes and shapes depending on the intended use or use.

In particular, in recent years, a thin thin film has been made of a plurality of overlapping structure.

For example, Patent Registration No. 10-0701586 (Platform Catalytic Reactor) is configured to sequentially stack a diffusion plate, a reaction plate, and a collection plate so that the reaction material undergoes a reforming reaction while passing through these plates.

However, in the case of the conventional plate-type reformer, the thickness is thin and convenient to carry, but the following problems occur.

   1) It is advantageous to make the flow path because it is thin, but when the flow path is complicated and the direction of fluid changes frequently, the direction of travel changes rapidly, causing a lot of pressure loss.

   2) This pressure loss causes the fluid to be discharged at a higher pressure than the loss in order to secure a proper amount to cause the reforming reaction, so that the size of the delivery device is increased and the delivery pressure of the delivery device is also increased. Was created.

   3) If the reformer uses an endothermic reforming reaction, an energy source for supplying heat (energy) required for the reaction must be separately configured. On the contrary, in the case of exothermic reaction, the cooling means must be configured so that the reaction temperature does not rise too much. there is a problem.

   4) As a result, not only the energy utilization efficiency is lowered, but also the energy source or the cooling means must be provided, so that the size of the reformer is increased.

The present invention has been made in view of the above-mentioned, it is to provide a plate-type reformer that can distribute the fluid to each reaction plate to improve the pressure loss due to the fluid flow and to increase the heat exchange efficiency of the exothermic reforming reaction and endothermic reforming reaction Its purpose is to.

By arranging the remaining components to be mirror symmetrical, and the supply and discharge flow paths of the fluid and the catalyst are arranged on the same line, it is possible to reduce the pressure loss by distributing and supplying the fluid supplied to the exothermic reaction chamber and each endothermic reaction chamber. Rather, it is configured to improve the thermal efficiency by lowering the temperature toward the outside centering on the exothermic reaction plate.

In addition, the present invention is characterized in that the flow of the fluid between the endothermic reaction plate and the preheating guide plate, the exothermic reaction plate and the preheating guide plate constitute a flow path in a form similar to eight characters.

In addition, the present invention is characterized in that the moving passages of the fluid (gas used as fuel, catalyst, and exhaust gas, etc.) provided to each of the reforming plates are arranged on the same line, respectively.
