[0027] Working principle:

[0028] When the carbon dioxide is subjected to dehydrogenation and deoxidation and decarburization operation:

[0029] The first valve 3 and the third valve 12 are opened, the operator passes the gas into the reaction kettle 1 through the gas inlet pipe 4, the external power supply of the air pump 11 is connected, the air pump 11 is started to exhaust the air in the reaction kettle 1, so that more gas to be processed can exist in the reaction kettle 1 (a small amount of gas can be passed into the reaction kettle 1 during the first processing, and the working time of the air pump 11 can be increased after the second processing, so that the amount of gas to be processed in the reaction kettle 1 is increased), after the aeration is completed, the first valve 3 and the third valve 12 are closed, the external power supply of the heating plate 7 is connected, and the heating plate 7 is started to heat the gas to be processed in the reaction kettle 1, the electric heater 1 is only used at the beginning of the work, and the subsequent reaction releases heat to maintain the balance of the reaction, the reaction kettle 1 oxidizes most of the combustible components such as CO, hydrogen and methane to generate carbon dioxide and water, the water will gather at the lower end of the reaction kettle 1, and after a certain amount of water is accumulated after not being used or being used for a period of time, the water can be discharged by opening the second valve 6, and according to the above operation, continuous processing can be carried out.
