Abstract

The invention discloses a hydrogen producing system. The hydrogen producing system comprises a direct-current power source, a hot box, a water steam generator, a first gas preheater, a first heat exchanger, a gas and water separation drying device and a hydrogen pressurizing device; a solid oxide electrolytic cell stack is arranged in the hot box, the direct-current power source comprises a hydrogen electrode wire and an oxygen electrode wire, the hydrogen electrode wire and the oxygen electrode wire are both connected with the solid oxide electrolytic cell stack, the water steam generator isused for conveying generated water steam to the first gas preheater to be heated, the heated water steam is conveyed to the hot box through a pipeline, the hot box is used for conveying the produced hydrogen to the first heat exchanger through the pipeline, the first heat exchanger is used for cooling the hydrogen and conveying the cooled hydrogen to the gas and water separation drying device, andthe gas and water separation drying device is used for carrying out gas and water separation on the hydrogen and conveying the dried hydrogen to the hydrogen pressurizing device to be stored. The hydrogen producing system can be achieve industrialized and large-scale hydrogen producing.

Description

technical field [0001] The invention relates to a hydrogen production system. Background technique [0002] As an energy carrier, hydrogen plays an increasingly important role in the current society. At present, the world consumes more than 50 million tons of hydrogen, of which 95% is directly or indirectly converted from fossil resources, and the remaining 5% is from electrolyzed water. In the process of fossil resource conversion, the production of high-purity hydrogen is often produced in the form of CO 2 At the expense of emissions, the hydrogen content of fossil resources itself determines the CO2 in a sense. 2 For example, the process of producing hydrogen from natural gas can emit less CO 2 , while CO in the process of hydrogen production from coal gasification 2 emissions are far greater than the former. Therefore, only when the hydrogen production process does not involve CO 2 In the case of emissions, the above process can reduce CO emissions 2 meaning. The...
