PURPOSE:To make a waste gas processing device compact by using heat energy procuded in removing CO2 for heating waste gas, leading fluid medium including COCO3 produced by absorbing CO2 to another fluid bed for regeneration, rising temperature so as to form grains mainly including CaO, and circulating the grains to a fluid bed for CO2 for reuse. CONSTITUTION:Waste gas from a fuel cell 1 including CO2, H2, H2O, etc., is led to a fluid bed 3 consisting of grains mainly including CaO for removing CO2, so that CO2 is removed, and heat energy produced by removal of CO2 is used for heating waste gas. The heated waste gas is supplied to a reformer 5. Fluid medium including CaCO3 produced by absorption of CO2 is led to a fluid bed for regeneration 11. Temperature of this fluid medium is risen for removing CO2 to form it into grains mainly including CaO. The grains mainly including CaO are circulated to the fluid bed 3 to be reused, thereby a waste gas processing device is made compact. |
