An automatic bioreactor

Abstract

The invention discloses an automatic bioreactor, which belongs to the technical field of microalgae cultivation. It includes a liquid collection tank, the inner wall of which is provided with a reflective layer, which is used to hold the culture solution for microalgae cultivation; the main shaft is vertically installed in the middle of the liquid collection tank, and is rotatably connected with the liquid collection tank; the said main shaft is provided with a spiral three-dimensional The spiral culture unit, the three-dimensional spiral culture unit is composed of a three-dimensional spiral transparent plate of equal width; the water distribution pipe is spirally arranged along the inner edge of the three-dimensional spiral culture unit, and there are evenly distributed water distribution holes corresponding to the upper surface of the three-dimensional spiral culture unit. The top of the water distribution pipe is connected to the submersible pump located in the sump at the bottom of the main shaft through the water inlet pipe installed in the main shaft; the light source device is arranged in sequence along the spiral light groove on the side wall of the main shaft; the vertical axis wind drive device is equipped with Vertical axis wind rotor, gear transmission, electric motor and battery. The invention purifies air and sewage while harvesting high value-added algae biomass, thereby reducing the cost of cultivation and purification.

Description

technical field [0001] The invention relates to the technical field of microalgae cultivation, in particular to an automatic bioreactor. Background technique [0002] Microalgae are photoautotrophic organisms that are widely distributed in freshwater, oceans and various soils on the earth. They have the characteristics of rapid growth, high photosynthetic efficiency, strong adaptability, and asexual reproduction. Microalgae can use light energy, CO2, organic carbon, ammonia nitrogen, organic phosphorus and other substances in wastewater as carbon, nitrogen and phosphorus sources, and absorb heavy metals to purify wastewater; they can also absorb gases such as CO2 in the atmosphere as their own metabolic carbon At the same time, microalgae contain a variety of high value-added biologically active substances, such as polyunsaturated fatty acids, algal polysaccharides, phycocyanin, astaxanthin, carotene, etc., with antibiotics, anti-cardiac It has medicinal value and health ca...

AI Technical Summary

Problems solved by technology

[0005] At present, the research direction is mainly to explore the cultivation method of microalgae, which is mainly to blindly enhance the light intensity and couple the microalgae culture with various ratios of wastewater. There are relatively few studies on aesthetics and biological carbon fixation. Moreover, most photobioreactors occupy a large area, cannot be folded and contracted, have a low utilization rate of light, and cannot use clean energy such as wind energy and light energy as The energy supply and operation of the bioreactor, and the research on sewage treatment and air purification are rarely involved. Therefore, it is necessary to propose an automatic bioreactor to realize the automatic adjustment of light intensity and enhance the efficiency of biological carbon sequestration, thereby While purifying air and sewage, harvest high value-added algae biomass, and use wind energy to cultivate microalgae, reducing the cost of cultivation and purification
