specific Embodiment approach 1

[0021] Specific embodiment one: present embodiment adopts carbonaceous waste as the power generation method of SOFC fuel as follows:

[0022] Carbon-containing waste is added to the fuel pipe 4 of the power generation device using carbon-containing waste as SOFC fuel. The carbon-containing waste in the fuel pipe 4 first reacts with the residual oxygen in the reaction chamber 6 to generate carbon dioxide, and the carbon dioxide is then mixed with the fuel pipe 4. The carbon-containing waste reacts to generate carbon monoxide, and the generated carbon monoxide is adsorbed on the surface of the anode 3 of the solid oxide fuel cell. The carbon monoxide reacts with the oxygen ions transmitted by the electrolyte layer 2 to generate carbon dioxide and loses electrons at the same time. The electrons lost by carbon monoxide flow from the anode 3 to the cathode through the wire 1. Form current to supply power to the electrical equipment 7, wherein carbon-containing waste is continuously ...

specific Embodiment approach 2

[0023] Embodiment 2: This embodiment differs from Embodiment 1 in that the carbon-containing waste is leaves, branches, bark, roots, sawdust, straw, bellflower, coal, coal ash, raw coal or coke. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0024] Specific implementation mode three: combination figure 2 , Specific Embodiment 1 The power generation device using carbon-containing waste as SOFC fuel includes a cathode 1, an electrolyte layer 2, an anode 3, a fuel pipe 4 and a sealant plug 5, and it is characterized in that the anode 3 is a tubular with a closed bottom end The sealant plug 5 is inserted into the open end of the anode 3 to close the anode 3, the fuel pipe 4 is located inside the reaction chamber 6 formed by the sealant plug 5 and the anode 3, and the two ends of the fuel pipe 4 pass through the sealant The plug 5, the body of the fuel pipe 4 has an air hole; the outer surface of the anode is covered with an electrolyte layer 2, and the outer surface of the electrolyte layer 2 is covered with the cathode 1.

Abstract

The invention relates to a method and a device for generating power by using carbon-containing garbage as fuel, in particular relates to the method and the device for generating the power by using the carbon-containing garbage as the fuel of a solid oxide fuel cell (SOFC), and aims to solve the technical problem of high cost of hydrogen which serves as the fuel in an existing SOFC. The method comprises the following steps: adding the carbon-containing garbage into a fuel pipe (4); reacting the carbon-containing garbage with oxygen to generate carbon dioxide; reacting the carbon dioxide with the carbon-containing garbage to generate carbon monoxide; reacting the carbon monoxide with oxygen ions transferred by an electrolyte layer (2) to generate the carbon dioxide with loss of electrons; forming a current loop after the lost electrons of the carbon monoxide flow from an anode (3) to a cathode (1) through a wire. The device comprises the cathode (1), the electrolyte layer (2), the anode (3), the fuel pipe (4) and a sealing rubber plug (5). By the adoption of the method and the device, the zero-cost operation of the SOFC is realized. The method and the device belong to the field of power generation through the carbon-containing garbage.

Description

technical field [0001] The invention relates to a power generation method and device using carbon-containing garbage as fuel. Background technique [0002] Solid oxide fuel cell (SOFC) is an energy conversion device that can directly convert the chemical energy in fuel such as hydrogen into electrical energy without being limited by the Carnot cycle, so it has a high energy conversion rate. Usually, the energy conversion rate of SOFC can reach 60%. If the cogeneration method is adopted, the energy conversion rate can reach 80%, which is 2 to 3 times that of ordinary thermal power generation. In addition, SOFC is a clean energy system. The traditional fuel of SOFC is hydrogen, and the final reaction product of the system is water, which can be directly consumed by humans. In the 21st century, when human beings are facing severe energy and environmental problems, the advantages of SOFC are more prominent, and its large-scale development and utilization have also attracted mu...
