Problems solved by technology

However, at present, the micro-reactors for methanol reforming hydrogen production mostly adopt the laminated structure of metal cavity plates, and the micro-reactors are sealed by graphite sheets. As the performance of micro-reactors increases, the number of graphite sheets used increases. It is more difficult to guarantee the airtightness of the microreactor, especially in the application of high temperature and high pressure, it is a difficult problem to take into account the airtightness and detachability of the microreactor and the replaceability of the reaction carrier

Abstract

The invention discloses a self-heating type methanol reforming hydrogen production micro-reactor with both sealing and disassembly properties, which is mainly used to realize the reliable sealing of the micro-reactor in high-temperature and high-pressure applications, as well as the detachable, The reaction carrier can be replaced. The invention consists of an inlet combustion evaporation module, a combustion evaporation module, a combustion mixing chamber plate, a combustion reaction module A, a reforming reaction module A, a combustion reaction module B, an outlet cavity plate module and the like. The module is composed of cavity plates, and the cavity plates are welded together in the form of vacuum "surface-surface" welding, which ensures the reliable sealing of the combination of the reforming cavity plate and the combustion cavity plate; the vacuum "surface-surface" of the present invention The side of the structure after welding "surface" is sealed in the form of sealing pressure plate, graphite sealing sheet, bolts and nuts, which ensures the overall sealing of the microreactor, the detachability of the microreactor, and the replaceability of the reaction carrier.

Description

technical field [0001] The invention specifically relates to a self-heating type methanol reforming hydrogen production micro-reactor with both sealing and disassembly properties, which is used to ensure that the heat supply process of the methanol reforming hydrogen production reaction is different in the micro-reactor. There are no cross-gas and gas leakage problems between the flow path gases, and the detachable self-heating methanol reforming hydrogen production micro-reactor and the replaceable reaction carrier are realized. Background technique [0002] At present, the hydrogen supply technology of hydrogen storage tanks used in hydrogen fuel cell vehicles has major safety problems in hydrogen storage, hydrogen transportation, and hydrogen use. The hydrogen supply solves the technical shortcomings of the hydrogen supply method of the hydrogen storage tank in terms of safety. However, at present, the micro-reactors for methanol reforming hydrogen production mostly adop...
