A Spiral Plate Membrane Reactor for Hydrogen Production with Atomized Feed of Liquid Fuel

Abstract

The invention discloses a hydrogen-producing spiral plate membrane reactor with liquid fuel atomized feed, which belongs to the field of hydrogen energy, and includes a preheating chamber, a gasification buffer chamber and an ignition chamber located in the central part, and a coating on the outer periphery of the central part. The combustion chamber and the reforming chamber, the reforming chamber and the combustion chamber are alternately covered in a double helix form to form a double helix structure chamber; the preheating chamber communicates with the inlet of the reforming chamber through the gasification buffer chamber; the preheating chamber, gasification buffer As a whole, the chamber and the reforming chamber are closed with the ignition chamber and the combustion chamber; There is an outlet, and the outlet of the reforming chamber is equipped with a hydrogen membrane purifier. The invention can maximize heat absorption and release coupling, improve heat transfer efficiency and heat energy utilization rate, convert liquefied hydrogen-containing raw materials into high-purity hydrogen, and provide a compact structure and rationally designed hydrogen production for downstream technologies that require higher hydrogen purity Reactor, strong practicability.

Description

technical field [0001] The invention belongs to the field of hydrogen energy, and relates to a hydrogen production reactor, in particular to a hydrogen production spiral plate membrane reactor for liquid fuel atomized feed. Background technique [0002] As early as the 19th century, many countries realized that energy sources such as oil and coal were increasingly depleted. Considering the current energy reserves, they are not enough to support mining for 200 years. As a renewable and clean energy, hydrogen energy has attracted the attention of various countries. At present, many developed countries are already in the research stage of practical application of hydrogen energy. Many countries in Europe and the United States have applied hydrogen energy to hydrogen vehicles to solve the problem of transportation energy consumption; countries such as Japan and South Korea have also considered their own national conditions and used hydrogen energy for household use.

Problems solved by technology

[0005] In summary, the current liquid fuel reforming hydrogen production reactor mainly has the following problems: (1) The gasification process of liquid fuel is relatively long, and it is necessary to leave enough space in the reactor for its gasification or to connect an external evaporator, which is not conducive to Compact structure; (2) The heat transfer process between the reforming chamber and the combustion chamber is insufficient due to the contact path and time limit, resulting in heat loss; (3) The ppm level requirement of the CO concentration in the downstream process causes the reformed gas to react in the outflow Further hydrogen purification is required after the reactor before application
