Embodiment 1
[0033] as attached figure 1 As shown, it is an integrated switchable chemical loop hydrogen production device of the present invention, which includes an integrated chemical loop reactor and two CaO reactors. The integrated chemical loop reactor is divided into three reactors on average, and the three reactors are divided into two Adjacent to each other, each reactor is provided with five inlets and five outlets respectively. The five inlets of the chemical chain reactor I1 respectively pass through the valve a10, the valve b11, the valve c12, the valve d13 and the valve e14 and the fuel gas pipeline 61, water Steam line 62, air line 63, CO 2 The pipeline 64 communicates with the gas mixture I pipeline 66, and the five outlets of the chemical chain reactor I1 respectively pass through the valve f15, the valve g16, the valve h17, the valve i18 and the valve j19 and the CO 2 and water vapor pipeline 65, mixed gas I pipeline 66, mixed gas II pipeline 67, H 2 It communicates wit...

The invention discloses an integrated switch chemical looping hydrogen production apparatus. The apparatus comprises an integrated chemical looping reactor and two CaO reactors, the internal of the integrated chemical looping reactor is divided into three reactors, every reactor is provided with five inlets and five outlets, every CaO reactor is provided with an inlet and two outlets, and the inlets and the outlets are connected with different gas pipelines through valves. Hydrogen is produced through the reduction and oxidation cycle process of an oxygen carrier by adopting the apparatus, a reaction is divided into three reaction phases with same reaction time, and the three reactors in the integrated chemical looping reactor are controlled to be respectively positioned in different phases in order to realize circulating and continuous production of hydrogen. The apparatus realizes immobilization reaction of the oxygen carrier, avoids wearing induced by flowing of the oxygen carrier in all the reactors, and improves the utilization rate of the oxygen carrier; and the apparatus and the method are ingeniously designed, so heat transfer among the reactors is enhanced, and continuous production is realized.
Description
technical field [0001] The invention relates to an integrated switchable chemical chain hydrogen production device and method, in particular to a 2 Captured switchable chemical chain hydrogen production system and method. Background technique [0002] As an important material basis for human survival and development, fossil energy such as coal, oil, and natural gas has supported the progress of human civilization and economic and social development for nearly 200 years from the 19th century to the 20th century. However, as the most important energy consumed in the world at present, traditional fossil energy not only obtains energy but also produces a large amount of CO in the process of utilization. 2 , leading to the "greenhouse effect". Therefore, enhancing the CO 2 The capture and storage of energy is particularly important, and there is an urgent need to research and develop new clean and efficient energy utilization methods. [0003] In 1983, German scientists Richt...
