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 switchable chemical chain hydrogen production device, which comprises an integrated chemical chain reactor and two CaO reactors. The integrated chemical chain reactor is divided into three reactors, and each reactor is respectively equipped with five There are three inlets and five outlets, and the CaO reactor is provided with one inlet and two outlets respectively, and the inlets and outlets are connected to different gas pipelines through valves. With the device of the present invention, hydrogen production can be realized through the cycle process of the oxygen carrier being reduced and oxidized, the reaction is divided into three reaction stages with the same reaction time, and the three reactors inside the integrated chemical chain reactor are controlled to be in the Different stages, so as to realize the cycle and continuous production of hydrogen production. The device of the present invention realizes the immobilization reaction of the oxygen carrier, avoids the wear caused by the flow of the oxygen carrier in each reactor, and improves the utilization rate of the oxygen carrier; the design is ingenious, and the heat transfer between the reactors is enhanced, Realized continuous production.
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...
