Problems solved by technology

If the gap size is too large, the size of the bubbles coming out of the pump will be large, and the refinement effect of the bubbles will be poor; if the gap size is too small, the efficiency of the pump will be low and the installation accuracy will be difficult to guarantee

Abstract

The invention discloses a tubular photobioreactor CO2 aerating device, comprising a filtering device, a valve, a fluid flowmeter, a valve, a gas flowmeter, a conical rotor labyrinth spiral pump and a tee joint, wherein the conical rotor labyrinth spiral pump comprises a pump inlet, a stator, a conical rotor and a pump outlet. During the working process, the filtering device is placed in a tubular photobioreactor water tank, and the tee joint is connected with a light reacting tube through a thread or a flange; an electric motor drives the conical rotor to rotate at high speed, so as to respectively suck the mixed gas of CO2 and air and fluid in the water tank to the conical rotor labyrinth spiral pump; gas-fluid two-phase fluids perform circling motion and axial motion along with the conical rotor along with a working cavity body formed by the conical rotor and the stator; the mixed gas is gradually scrubbed and sheared at high speed continuously, and finally, massive trace bubbles are formed and mixed in the fluid, and then flowed into a light reaction pipeline. The tubular photobioreactor CO2 aerating device is good in bubble refining effect, high in pump efficiency; the microalgae can absorb CO2 completely and well perform the photosynthesis.

Description

technical field [0001] The invention relates to the field of microalgae cultivation engineering, in particular to a tubular photobioreactor CO 2 Aeration device. Background technique [0002] Microalgae are photosynthetic microorganisms widely distributed on land and in the ocean. They can effectively use light energy, carbon dioxide, water and inorganic salts to synthesize proteins, fats, carbohydrates and high value-added biologically active substances. Therefore, they are widely used in food, energy and The environmental field has broad application prospects. [0003] Large-scale and high-density cultivation of microalgae is a key link in the microalgae biological industry, and this relies on high-performance photobioreactors. Therefore, research on photobioreactors for cultivating microalgae has always been the focus of research in the microalgae biological community. question. [0004] At present, there are mainly two types of photobioreactors for microalgae cultivat...
