Abstract

The invention relates to the equipment for intensification of microalgae cultivation processes by selective extraction and introduction of CO2 from the cleaned biogas and can be used in the agro-industrial field, as well as at industrial waste water biological treatment stations.The combined plant for selective extraction of CO2 from biogas and cultivation of microalgae comprises a block for CO2 extraction from biogas, a microalgae cultivation reactor (18) and a microalgae removal block. The block for CO2 extraction from biogas comprises a sealed container (1), made two-section, the lower section of which comprises a biogas post-treatment block, inside which is placed a housing (3) with conical bottom. Inside the housing (3) is installed a mesh container (7) with a load (8) of iron-coke galvanic pair, and in the upper part an electric vibrator (9) with a nozzle (10), connected to a bubbler (11), mounted in the upper section of the block for CO2 extraction from biogas, which also comprises a biogas drainage block (12), an injector (14), a downspout duct (15), connected to a conduit (16), which is connected to a node (17) for ammophos additives dispensing into the microalgae cultivation reactor (18), in which are placed a heat exchanger (19), LED lamp units (20) and a cylindrical electroflotation block (21), comprising an electrode assembly (22) built-in congruently to its axis, connected to a constant-current source (23), and a funnel (24), connected to a hose (25), which communicates with a reservoir (26) of a drum filter (27) of the microalgae removal block, which further comprises an auxiliary electrode assembly (29), mounted in the reservoir (26) of the drum filter (27), a scraper (30) and a capacity (31), connected to a recirculation pump (32), the outlet of which is connected via a conduit to the injector (14), at the same time the drum filter (27) is connected to a pump (28).
