Hydrogen production system by methanol steam reforming in explosion-proof micro-channel reactor

Abstract

The application discloses an explosion-proof micro-channel reactor methanol steam reforming hydrogen production system and belongs to the technical field of methanol hydrogen production. The system comprises a cabin body and a plurality of blowing mechanisms. The inner cavity of the cabin body is separated into mutually independent treatment cavities, reaction cavities and capture cavities by partitions. The bottom of the cabin body is provided with a common cavity. The treatment cavities, the reaction cavities and the capture cavities are individually communicated with the common cavity through respective isolation valves and pressure relief valves. The plurality of blowing mechanisms are used for blowing inert gas into the treatment cavities, the reaction cavities and the capture cavities. The core processes of methanol reforming hydrogen production, such as material mixing, heat exchange vaporization, reforming reaction, gas-liquid separation and carbon capture, are arranged in the treatment cavities, the reaction cavities and the capture cavities, thereby reducing the floor area and improving the space utilization. The hydrogen concentration in the leakage chamber is rapidly diluted through the plurality of blowing mechanisms, the explosion or combustion risk caused by hydrogen exceeding the standard is reduced, the safety of personnel and equipment is effectively ensured, and the use safety is improved.
