Methanol-to-hydrogen converter convenient for replacing catalyst

The methanol-to-hydrogen converter comprises a tank body, a gas inlet chamber, a reaction chamber and a gas outlet chamber are sequentially arranged on the tank body, and tube plates are arranged among the gas inlet chamber, the reaction chamber and the gas outlet chamber. The conversion tubes are arranged on the tube plate; the quick-mounting structure is arranged on the conversion tubes and is convenient for quickly replacing a catalyst; the quick-assembly structure comprises a threaded groove which is formed in one end of the conversion pipe and is communicated with the gas outlet chamber, an elastic supporting piece which is arranged on the threaded groove, and a high-temperature ceramic ball which is arranged on the elastic supporting piece, is resistant to high temperature and does not react with the catalyst; through the arrangement of the quick-mounting structure, the catalyst in the conversion tube is supported by the elastic supporting piece and the granules, so that the catalyst in the single conve
