The light organism reaction device comprises a turbulence type multilevel spherical reactor, a reactor constant-temperature sleeving, a circulation diversion pipe, a circulation diversion pipe constant-temperature sleeving, a settling tank, a gap inlet, a gas distributor, a feeding opening, a light source, a constant-temperature waterbath, a gas flowmeter and the like. The light organism reaction device is a semicontinuous circulation gas lifting type light organism reactor, the cell suspension rises in the reactor in a turbulent mode in the flashing environment, and constant temperature cultivation can be achieved. The light organism reaction device has the advantages of being moderate in cultivation, good in liquid mixing, high in gas-liquid mass transfer intensity, low in shear force, quick in growth, intensive in biological cell density, capable of being harvested continuously and the like, so that the light organism reaction device has a high economic value and a high industrial application prospect.

Description

technical field [0001] The invention relates to a novel photobiological reaction device, which is suitable for the cultivation of microalgae and other photosynthetic organism cell suspensions. Background technique [0002] Microalgae is a kind of biological resource with great application value. The artificial cultivation of microalgae by photobioreactor is an important way to solve the large-scale cultivation and amplification of microalgae. [0003] At present, there are mainly two types of closed photobioreactors: pipeline type and crate type. In the two types of photoreactors, the circulation of the culture medium adopts two methods: pump and air lift, because the shearing effect of the air lift cycle on the cells is relatively large. Small, while providing algae fluid flow, it also facilitates gas exchange. [0004] Chinese patent CN1472305A reports an integrated airlift photobioreactor, which includes a tank, a riser, and a gas distributor, wherein the cylindrical ris...
