A hydrogen shaft furnace ironmaking system and method using electric energy heating, the system includes a water electrolyzer, a hydrogen storage tank, an electric energy heating hydrogen shaft furnace, a heat exchanger, and a gas mixing tank; the furnace body is provided with a microwave heating section, a middle section, The induction heating section, the cooling section and the screw discharger, the air inlet pier is below the cooling section, and the water electrolyzer, hydrogen storage tank, heat exchanger, gas mixing tank are connected with the air inlet of the air inlet pier in sequence. The method is as follows: (1) The hydrogen gas generated by the electrolysis of the water electrolyzer is passed into the hydrogen storage tank; (2) The hydrogen gas is passed into the coil in the heat exchanger, discharged into the gas mixing tank, and passed into the furnace body through the air inlet pier; (3) Turn on the microwave radiation source and the induction coil; (4) Put the iron-containing material into the furnace body to exchange heat with the gas and undergo a reduction reaction; (5) After the iron-containing material passes through each section of the furnace body, it will generate direct reduced iron and discharge it. The method of the present invention avoids oxygen blowing at the upper part, can realize the direct recovery and utilization of part of the high-temperature tail gas on the top of the furnace, reduces energy consumption and operation cost, and can avoid pipeline material failure and other related safety accidents caused by hydrogen diffusion.
