Example Embodiment

[0054] Example 1

[0055] see figure 1 The present invention discloses a device for preparing hydrogen by using methanol water. The liquid storage container 10 is used to store liquid methanol and water, and the raw material transport device 50 transports the methanol and water raw materials in the liquid storage container 10 to the hydrogen production equipment 20 to prepare hydrogen, and the prepared hydrogen is transported to the membrane separation device. 30 to separate.

[0056] The exhaust heat exchange device 60 includes a second heat exchanger, and the second heat exchanger uses raw methanol and water as the cooling medium to cool the exhaust gas; the inlet of the heat exchange tube of the second heat exchanger is connected to the liquid storage container through a pipeline, and the first heat exchanger is connected to the liquid storage container. The outlet of the heat exchange tube of the second heat exchanger is connected to the hydrogen production equipment 20;...

Example Embodiment

[0059] Embodiment 2

[0060] The difference between this embodiment and Embodiment 1 is that in this embodiment, please refer to image 3 The equipment for preparing hydrogen uses methanol water to prepare hydrogen, and the equipment for preparing hydrogen includes a solid hydrogen storage container 40, a liquid storage container 10, a raw material conveying device 50, a hydrogen production equipment 20, a membrane separation device 30, and a tail gas heat exchange device. 60. The exhaust heat exchange device 60 is similar to that of the first embodiment.

[0061] The solid hydrogen storage container 40 and the liquid storage container 10 are respectively connected to the hydrogen production equipment 20; the liquid storage container 10 stores liquid methanol and water, and the solid hydrogen storage container 40 stores solid hydrogen.

[0062] When the hydrogen production system is started, the solid hydrogen in the solid hydrogen storage container 40 is converted into gase...

Abstract

The invention discloses equipment for preparing hydrogen from methanol and water. The equipment comprises a liquid storage container, a raw material conveying device, hydrogen production equipment, a film separation device and a tail gas heat exchange device, wherein the liquid storage container is used for storing liquid methanol and water; the raw material conveying device is used for conveying the raw materials, namely, methanol and water, in the liquid storage container to the hydrogen production equipment so as to produce hydrogen; the produced hydrogen is conveyed to the film separation device to be separated; the tail gas heat exchange device comprises a second heat exchanger; the second heat exchanger takes the raw materials, namely, methanol and water, as cooling mediums to cool down a tail gas; an inlet of a heat exchange tube of the second heat exchanger is connected with the liquid storage container through a pipeline; an outlet of the heat exchange tube of the second heat exchanger is connected with the hydrogen production equipment; the temperature of the raw materials is raised through heat exchange of the heat exchange tube of the second heat exchanger, and meanwhile the temperature of the tail gas is reduced. Due to adoption of the equipment for preparing hydrogen from methanol water, a waste gas treatment device does not need to be arranged, so that the size of the equipment is reduced, and the mobility of the equipment is improved.

Description

technical field [0001] The invention belongs to the technical field of hydrogen preparation, and relates to a device for preparing hydrogen, in particular to a device for preparing hydrogen by using methanol water. Background technique [0002] Among the many new energy sources, hydrogen energy will become the most ideal energy source in the 21st century. This is because, in the case of burning the same weight of coal, gasoline and hydrogen, hydrogen produces the most energy, and the product of its combustion is water, without ash and waste gas, and will not pollute the environment; are carbon dioxide and sulfur dioxide, which can produce the greenhouse effect and acid rain, respectively. The reserves of coal and oil are limited, and hydrogen is mainly stored in water. The only product after combustion is water, which can continuously produce hydrogen and never run out. [0003] Hydrogen is a colorless gas. Burning one gram of hydrogen releases 142 kilojoules of heat, whi...
