The internal circulation reactor (IC reactor) is a form of anaerobic digester. It is primarily designed to treat wastewater. The IC reactor is an evolution of the UASB and EGSB digestion systems. The digester typically produces biogas with a high concentration methane (c80%). In essence the IC to improve digestion rates and gas yields. The foot print for the IC reactor is therefore typically smaller. However, it is taller due to the increased complexity of the reactor.
A direct air carbon capture device and method adapted for renewable energy sources
The application discloses a direct air carbon capture device and method suitable for renewable energy, and belongs to the technical field of carbon capture. The application adopts a double-helix winding type multi-channel internal circulation reactor, a central diffusion type air inlet pipe with a hole distribution is matched with a guide plate to realize multi-pass contact of gas; modified conductive adsorption filaments take carbon fibers as a substrate, are modified by graphite doped porous silicon dioxide coating and polyethylene imine impregnation, and high conductivity and high adsorption capacity are considered; direct Joule heating and vacuum assisted desorption are combined to realize rapid heating and desorption; a detection control system adjusts a heating voltage and a vacuum degree in real time according to energy supply fluctuation, compensates for insufficient energy supply, and guarantees stable desorption efficiency. The application has the advantages of rapid response, short cycle time and self-adaptive energy supply fluctuation, and is suitable for direct air carbon capture driven by renewable energy.
