System and method for trapping power plant smoke carbon dioxide by rice husk gasified coupled sodium silicate

Abstract

The invention discloses a system and a method for trapping power plant smoke carbon dioxide by rice husk gasified coupled sodium silicate. The system comprises a rice husk gasified coupled Na2SiO3 preparation furnace, a charge electric appliance, an electric field auxiliary fluidized reactor, a material separation apparatus, a dissolving device and a filter which are connected in sequence, whereinan input end of the rice husk gasified coupled Na2SiO3 preparation furnace is an inlet for synthetic raw materials, O2 and Na2CO3 solution, and an output end is also connected with a first heat exchanger; a second heat exchanger is arranged in the electric field auxiliary fluidized reactor; the material separation apparatus is two levels of cyclone separators which are connected successively, theupper output end of the two levels of cyclone separators is connected with a third heat exchanger, a lower output end of the two levels of cyclone separators is connected to the electric field auxiliary fluidized reactor, and an additional pipeline is arranged to connect a fourth heat exchanger and a dissolving device; and an output end of the filter is connected to the rice husk gasified coupledNa2SiO3 preparation furnace. The system is organic combined with a coal fired power generation system, and the smoke of a coal fired power station exchanges heat with a bed body to keep the temperature constant, and the scheme is low in investment cost and low in energy consumption.

AI Technical Summary

Benefits of technology

This patented technology describes methods for making useful products such as fertilizers or fuel cell bags made up mainly of waste biological material (biornage). By combining these processes together, it provides efficient ways to produce valuable chemicals without generating new ones like fossils. Additionally, this process helps reduce costs associated with disposal.

Problems solved by technology

This patented describes various methods used during capturing carbon dioxide from fossil fuel fired power generators that have been developed over time due to their negative impact on climate change concerns. These techniques include conventional thermal processes like burning or regenerative systems, but they also involve alternative solutions involving chemically adsorbed/absorptive dried CO_z/post-combusted capture technology called COSCO^{, which offers better control capabilities compared to other alternatives. Additionally, there may exist environmental threats associated with these substances, making effective removal even at home level difficult without expensive treatment options.}
