Embodiment Construction

[0026] The technical scheme of the solar internal light source microalgae bioreactor of the present invention will be further described below in conjunction with the accompanying drawings and examples.

[0027] Such as figure 1 As shown, the solar internal light source microalgae bioreactor of the present invention includes a runway pool 2, a stirring impeller 3, an air supply device 4 and a liquid supply device 5, and a solar internal light source module 1 is arranged in the runway pool 2. Among them, the solar inner light source module 1, the key component, is a light-transmitting container with an upward opening, an impermeable surrounding and a bottom, made of a transparent plate with a smooth surface, and the specific shape of the module can be in many ways.

[0028] figure 2 Shown is a way of the solar energy internal light source module 1, which is composed of a rectangular light guide groove and a deformed CPC groove 6; the cross section of the deformed CPC groove 6 ...

Abstract

The invention discloses a solar energy internal light source microalga bioreactor. The bioreactor comprises a runway pool, a stirring impeller, an air feeder and a liquid feeder, and solar energy internal light source modules are arranged in the runway pool. In the invention, the advantages of an open photo-bioreactor and the advantages of a closed photo-bioreactor are fully combined through installing the solar energy internal light source modules having a simple structure and a low cost on the basis of the runway pool. The bioreactor disclosed in the invention, which allows the deep internal of an alga liquid to be illuminated, greatly increases the illumination surface area volume ratio of the alga liquid in a culture pool, improves the solar energy utilization rate of the photo-bioreactor and greatly increases the culture density of the open photo-bioreactor. The wall suspension of microalga appears on the external surfaces of the modules, the external surfaces of the modules are smooth and structured and have no protruding parts, and the installed modules can be dismounted at will, so automatic batch cleaning or manual cleaning is convenient.

Description

technical field [0001] The invention belongs to the technical field of solar thermal utilization and bioengineering, and in particular relates to a microalgae bioreactor with solar internal light source. Background technique [0002] Microalgae can be cultivated in open ponds or in closed photobioreactors. The former is a device commonly used in large-scale production at present. It has simple technology and low construction and production costs. The disadvantage is that the utilization rate of solar energy is low, and the cultivation density and yield per unit area are naturally low. The main reason is that the ratio of illuminated surface area to volume is small; Benefiting from the large ratio of the illuminated surface area to the volume, it has a higher solar energy utilization rate, and the cultivation density and yield per unit area are much larger than the former. The disadvantage is that the technology is complicated, the construction and production costs are high, ...
