Embodiment 1

[0051] In the present embodiment, the spectroscopic method of the array photobioreactor comprises the following steps:

[0052] Step 1, a plurality of photobioreactors 1 are arranged in parallel in front and back, and arranged in an array at a certain interval on a horizontal plane, such as image 3 shown;

[0053] Step 2. With the change of the sun's altitude and azimuth, adjust the elevation angle α of the effective cultivation surface of the photobioreactor so that the vertical shadow length (i.e. the length of the normal shadow 4) produced after the sunlight is projected onto the photobioreactor 1 value) is not less than the distance between the bottom edges of adjacent photobioreactors in the shadow length direction.

[0054] The photobioreactor 1 in this embodiment is a device for cultivating photosynthetic organisms on the surface by means of liquid, and the materials of each photobioreactor 1 can be the same or different.

[0055] In this embodiment, a horizontal sha...

Embodiment 2

[0061] The similarities between this embodiment and Embodiment 1 will not be repeated here.

[0062] The difference between this embodiment and Embodiment 1 is: there are at least two photobioreactors 1 in Embodiment 1, and they are arranged in a single row; the arrayed photobioreactors 1 in this embodiment are multiple rows and multiple columns, Parallel front and back, straight lines left and right, and arranged in an array at a certain distance, such as Figure 5 shown.

[0063] In this embodiment, the adjustment of the vertical shadow length generated after the sunlight is projected onto the photobioreactor 1 is the same as that in embodiment 1, and it is also realized by adjusting the elevation angle α of the effective cultivation surface of the photobioreactor 1. The specific adjustment principle and process are as described in Embodiment 1, and will not be repeated here.

Embodiment 3

[0065] The similarities between this embodiment and Embodiment 1 will not be repeated here.

[0066] The differences between this embodiment and Embodiment 1 are as follows.

[0067] In the present embodiment, the spectroscopic method of the array photobioreactor comprises the following steps:

[0068] Step 1. Multiple photobioreactors are arranged in parallel in front and back, and arranged in an array at a certain distance on a horizontal plane, such as image 3 As shown; the photobioreactor in this embodiment is only arranged in one row.

[0069] Step 2. With the change of the sun's altitude and azimuth, and the changes of the sun's altitude and azimuth at each time of the year, adjust the azimuth β of the effective breeding surface of the photobioreactor so that the sunlight is projected to the photobioreactor The resulting vertical shadow length (that is, the length of the normal shadow 4) is not less than the distance between the bottom edges of adjacent photobioreacto...

Abstract

The present invention discloses an array type photobioreactor light splitting method, and belongs to the technical field of microalgae culture. The array type photobioreactor light splitting method comprises that: 1, at least two photobioreactors are arranged on the ground in a front-rear parallel manner and in an array manner at a certain interval, wherein the orientations of the two photobioreactors are free; and 2, along with the changes of the sun altitude angle and the azimuth angle, at least one of the elevation angle alpha and the azimuth angle beta of the effective breeding surface of the photobioreactor is adjusted, such that the length of the vertical shadow produced after sunlight projects onto the photobioreactor is not less than the distance between the adjacent photobioreactor bottom edges in the vertical shadow length direction. According to the present invention, the alpha angle and/or beta angle is adjusted, such that the direct illumination does not produce the light leakage on the ground so as not to cause energy loss.

Description

technical field [0001] The invention relates to a spectroscopic method for at least two photobioreactors, in particular to a spectroscopic method for arrayed photobioreactors, and belongs to the technical field of microalgae cultivation. Background technique [0002] In the large-scale cultivation of microalgae, open pools and track pools have simple structures and low energy consumption, but the light-splitting effect is poor, and the surface cells often see too much light, and the inner cells hardly see light, and the overall light utilization rate is low. However, in the prior art, the photobioreactors in the array-type large-scale photobioreactor culture technology are regularly and fixedly arranged on the ground. The light on the ground will also change accordingly. When the sun's altitude angle or azimuth angle is large, there will be light leakage between adjacent photobioreactors directly shining on the ground, a large amount of light energy will be lost, and the uti...
