Problems solved by technology

[0007] 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. Therefore, it is necessary to propose an umbrella-type tower photobioreactor to realize automatic adjustment of light intensity and enhance the efficiency of biological carbon fixation, thereby purifying air and sewage. While harvesting high value-added algae biomass

Embodiment Construction

[0034] The specific implementation of the invention will be further described below in conjunction with the drawings.

[0035] Such as Figure 1-3 As shown, the culture solution tank 20 has a reflective layer on its inner wall for holding the culture solution inoculated with microalgae. The culture solution tank 20 is in the shape of a "bowl", the inner surface of which is coated with a total reflection mirror film or pasted with tin foil, the side wall of the "bowl" is inclined; its bottom surface is provided with a universal wheel 30 for walking. A water inlet 23 is provided at the bottom of the culture solution tank 20. The side wall and bottom of the "bowl-shaped" have a certain inclination angle, and the light source is projected into the light guide plate 11 and the culture medium suspended at the low end through the specular reflection and diffuse reflection of the side wall and the low end, and the light source is fully utilized. The culture medium tank 20 is Polymer tr...

Abstract

The invention discloses an umbrella tower type photobioreactor and belongs to the technical field of microalgae cultivation. The umbrella tower type photobioreactor comprises a culture solution tank, a shaft rack and a light source device, wherein a reflective layer is arranged on the inner wall of the culture solution tank; the culture solution tank is used for containing a culture solution inoculated with microalgae; the shaft rack is vertically arranged in the middle of the culture solution tank; a plurality of umbrella-shaped culture units of which the shapes are gradually reduced according to the progressively increased height are arranged on the shaft rack; the culture units are used for forming an umbrella-shaped light guide plate; a horizontal liquid storage tank is arranged on the top of the shaft rack and connected with a submerged pump positioned in the culture solution tank through a liquid inlet pipe; and the light source device is an LED lamp or a fluorescent lamp and is arranged along the shaft rack. According to the umbrella tower type photobioreactor disclosed by the invention, synchronous adjustment of dip angles of the multi-layer umbrella tower type culture units is realized by a photosensitive hydraulic system, the illumination intensity of the culture units is further regulated, and the light utilization rate is improved.

Description

Technical field [0001] The invention relates to the technical field of microalgae cultivation, in particular to an umbrella-shaped tower photobioreactor. Background technique [0002] Microalgae are light-energy autotrophic organisms, which are widely distributed in freshwater, ocean 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 sources, nitrogen sources and phosphorus sources, and absorb heavy metals to purify wastewater; they can also absorb atmospheric CO2 and other gases as their own metabolic carbon Source, produce O2 to fix CO2 to purify the air; at the same time, the microalgae contains a variety of high value-added biologically active substances, such as polyunsaturated fatty acids, algae polysaccharides, phycocyanin, astaxanthi...
