Trap type carbon replenishing device for culturing microalgae of opened pool and carbon replenishing method thereof

摘要

The invention relates to the field of microalgae culturing, in particular to a trap type carbon replenishing device for culturing microalgae of an opened pool and a carbon replenishing method thereof. The trap type carbon replenishing device for culturing microalgae of the opened pool comprises a trap type container (1), a partition board (2) and an air distributor (3), wherein the air distributor (3) is arranged on a culture liquid inlet portion of a trap type carbon replenishing device (6), the thickness of the culture liquid inlet side of the trap type carbon replenishing device (6) is 0.5 to 2 times as the depth of a culture liquid layer of the opened pool, the distance between the lower end of the partition board (2) and the bottom of the trap type container (1) is 0.5 to 2 times as the thickness of the culture liquid inlet side of the trap type carbon replenishing device (6), the upper end of the partition board (1) is higher than the wall of the trap type container, and the width of the partition board (2) is matched with that of the trap type container (1). The carbon replenishing device prolongs air-liquid contact time, reduces depth of the container, accordingly reduces flowing resistance of fluid in the carbon replenishing device and saves energy consumption.
