System for preventing inflow pulverization of methanol-to-hydrogen catalyst

The utility model discloses a system for preventing methanol hydrogen production catalyst inlet water pulverization, which comprises a vaporizer, a methanol hydrogen production reactor and a heat exchanger, the vaporizer is communicated with the methanol hydrogen production reactor through a first pipeline, and the methanol hydrogen production reactor is communicated with the heat exchanger through a third pipeline. A second pipeline is arranged between the first pipeline and the heat exchanger, and safety interlocking control parts are arranged on the first pipeline and the second pipeline. The device is ingenious in conception, compact and reasonable in layout and high in automation degree, when the methanol-to-hydrogen reactor is started, liquid water is effectively prevented from entering a catalyst in the methanol-to-hydrogen reactor in the methanol water heating and cooling processes, high-temperature steam enters the methanol-to-hydrogen reactor, and the safety of the reaction process is guaranteed. 本实
