Steam ejector for activated carbon production

The utility model discloses a steam ejector for activated carbon production, which comprises a processing device for releasing steam to perform activation reaction with raw materials, and a bearing device for containing and recycling gas and water is arranged at the bottom of the processing device. A heat exchange device used for absorbing gas heat and then transferring the heat again to reduce energy consumption is arranged in the middle of the bearing device. The heat exchange device comprises four heat absorption pipes, a plurality of heat absorption pieces are evenly distributed on the heat absorption pipes, and heat insulation pipes are arranged at the bottoms of the heat absorption pipes. According to the steam ejector for activated carbon production, energy is supplemented for follow-up steps through the design that the heat absorption pipe absorbs energy of mixed gas, and energy consumption is reduced; by means of the design that the heat absorption pipe cools the mixed gas, residual water vapor is re
