A controllable turbulent microalgae cultivation device that can effectively improve carbon sequestration efficiency

Abstract

The invention discloses a controllable flow-disturbing microalgae cultivation device which can effectively improve carbon fixation efficiency, comprising a reactor, an air chamber, a bubble generator and a diffuse flow swirling diffuser; the reactor is located on the air chamber On the side, the bubble generator is installed in the air chamber, which includes an octagonal tube, a water pump and a Venturi tube; the Venturi tube is connected to a connecting pipe, and the connecting pipe is connected to a hose after extending out of the air chamber; the hose It is connected with the bubble conveying pipe, and the bubble conveying pipe extends into the reactor; the diffuser swirling diffuser includes a motor, a transmission shaft and a cutting device; the cutting device includes a The three-layer cutting disc is provided with several thorns on the lower side of the upper cutting disc and the upper and lower sides of the middle cutting disc and the lower cutting disc. The present invention can CO 2 The formed bubbles are smaller in size and evenly distributed, thus greatly improving the carbon fixation and mass transfer efficiency of microalgae, which is very rich in the concept of energy saving and emission reduction.

Description

technical field [0001] The invention relates to the technical field of microalgae cultivation, in particular to a controllable disturbance type microalgae cultivation device that can effectively improve carbon fixation efficiency. Background technique [0002] Due to the large-scale development of human beings, industrial emissions of greenhouse gases, CO 2 The excessive emission of greenhouse gases has caused the problem of global warming to become more and more serious. The rising global temperature is enough to affect the survival of species in the world. Therefore, how to reduce greenhouse gas emissions has become a common goal of the world. [0003] Microalgae grow fast and are easy to grow on a large scale, and use microalgae biomass to absorb CO 2 Has been applied in engineering. Microalgae utilize CO 2 There are two forms, one is dissolved CO in solution 2 Molecules enter algal cells by direct diffusion form, the other is CO 2 The molecule is converted to HCO ca...
