The invention relates to an energy-saving environmentally-friendly simple revolution cylinder-type heating furnace. A converter inlet and a converter outlet are respectively arranged on the head and tail ends of the energy-saving environmentally-friendly simple revolution cylinder-type heating furnace, an annular heat-insulation layer is arranged between a converter outer furnace cylinder wall and a converter inner furnace cylinder wall, annular separation support members are uniformly distributed in the length direction of the converter outer furnace cylinder wall, the annular separation support members are connected with a support device through rollers, an electric heating device is arranged on the lower part of the inner side of the converter outer furnace cylinder wall, and a gas heating device is arranged on the side surface of the converter outer furnace cylinder wall. The energy-saving environmentally-friendly simple revolution cylinder-type heating furnace is advantaged in that an electric heating and gas heating coexisting mode is employed, according to the catalyst activation roasting technology requirement or the cost condition, the fact that the device operates for a long period stably is guaranteed, and compared with a conventional single heat source electric furnace or natural gas furnace, the energy-saving environmentally-friendly simple revolution cylinder-type heating furnace has a great advantage. On the basis that the process requirement is satisfied, the cost is effectively reduced.
