METHANOL VAPORIZING AND MIXING DEVICE, METHANOL HEATING REACTOR, METHANOL NON-FLAME HEATING DEVICE, AND CONTROL METHOD

摘要

A methanol vaporizing and mixing device (100), a methanol heating reactor (200), a methanol non-flame heating device, and a control method. A heat exchange tube (132) filled with a catalyst (131) is provided in an air preheating chamber (124) of the methanol vaporizing and mixing device (100); air heated by the air preheating chamber (124) and methanol for preheating are mixed, a catalytic oxidation reaction occurs in the heat exchange tube (132) of the air preheating chamber (124), and heat energy for heating air is released. A heat exchange tube (232) filled with a catalyst (231) is provided in a working medium heating chamber (224) of the methanol heating reactor (200), a catalytic oxidation reaction is performed, in the heat exchange tube (232), on a methanol gas mixture into which air is mixed, and heat energy is released to heat a working medium. The methanol non-flame heating device consists of the methanol vaporizing and mixing device (100) and the methanol heating reactor (200). The control method comprises: controlling an outlet temperature of the methanol gas mixture by adjusting a methanol flow for preheating, and controlling an outlet temperature of the working medium by adjusting a methanol flow for heating. The methanol non-flame heating device can achieve a full catalytic reaction of methanol, thereby facilitating reducing emission of air pollutants and avoiding a safety hazard caused by open fire.
