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 accompanying drawings.

[0035] Such as Figure 1-3 As shown, the culture solution tank 20 has a reflective layer on its inner wall, which is used to hold the culture solution inoculated with microalgae. The culture solution tank 20 is "bowl-shaped", its inner surface is coated with a film of total reflection mirror or pasted with tinfoil, and the side wall of the "bowl-shaped" is inclined; its bottom surface is provided with universal wheels 30 for walking. A water inlet 23 is provided at the bottom of the culture solution tank 20 . The "bowl-shaped" side wall and bottom 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 lower end, so as to make full use of the light source, and the culture liquid...

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 tower photobioreactor. Background technique [0002] Microalgae are photoautotrophic organisms that are widely distributed in fresh water, 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 in wastewater, ammonia nitrogen, organic phosphorus and other substances as carbon sources, nitrogen sources and phosphorus sources, and absorb heavy metals to purify wastewater; they can also absorb CO2 and other gases in the atmosphere as their own metabolic carbon source, producing O2 to fix CO2 to purify the air; at the same time, microalgae contain a variety of high value-added bioactive substances, such as polyunsaturated fatty acids, algae polysaccharides, phycocyanin, astaxanthin, carotene, etc....
