When bioreactor physical dimension is determined, due to direct sunlight, to be irradiated to the long angle of elevation alpha not only effectively cultivating face with bioreactor of the vertical shadow produced of bioreactor relevant, the azimuthal angle beta also effectively cultivating face with bioreactor is relevant, therefore effectively cultivate the angle of elevation alpha in face or/and azimuthal angle beta by adjustment bioreactor, adjust the shadow that shade that adjacent bioreactor produces blocks and produce on ground long.And the light-splitting method of this array optical bio-reactor of the present invention, sun relative position that can be concrete according to cultivation place, i.e. sun altitude and azimuths of the sun, adjustment array optical bio-reactor effectively cultivates the angle of elevation alpha in face or/and azimuthal angle beta, direct sunlight is irradiated to after on bioreactor, the long spacing be not less than between this adjacent bioreactor base of vertical shadow length direction of the vertical shadow produced, even if directing light shines without on the ground between light leak to adjacent bioreactor, thus noenergy loss, overall light utilization efficiency in effective raising large-scale cultivation.When the angle of elevation alpha of adjustment bioreactor is or/and azimuthal angle beta, the long spacing equaled between this adjacent bioreactor base of vertical shadow length direction of the vertical shadow produced after just in time making sunlight project bioreactor, namely just in time make between each adjacent bioreactor without mutually blocking, make adjacent bioreactor effectively unobstructed shade on cultivation face strictly speaking, then can ensure the even light in whole cultivation face, overall light utilising efficiency in further raising large-scale cultivation, realize the good spectrophotometric result of array optical bio-reactor, for photo bio provides stable suitable growing environment, ensure the speed of growth of photo bio, improve the Yield and qualities of photo bio.
Below enumerate five specific embodiments to set forth further the present invention.
Embodiment 1
In the present embodiment, the light-splitting method of array optical bio-reactor, comprises the steps:
Step 1, by parallel before and after multiple bioreactor 1, and be decorated in array in the horizontal plane with a determining deviation, as shown in Figure 3;
Step 2, along with sun altitude and azimuthal change, adjustment bioreactor effectively cultivates the angle of elevation alpha in face, and the vertical shadow long (i.e. the length value of normal shade 4) produced after making sunlight project bioreactor 1 is not less than the spacing between the adjacent bioreactor base of this shadow length direction.
Bioreactor 1 in the present embodiment is to be cultivated by liquid and for cultivating the device of photosynthetic organism in surface, and the material of each bioreactor 1 can be identical or different.
In the present embodiment, horizontal rotating shaft 2 is provided with in the bottom of bioreactor 1, by rotating light bio-reactor 1, even if it rotates around horizontal rotating shaft 2, as shown in Figure 4, and then the adjustment of realization to bioreactor 1 angle of elevation alpha, along with diminishing gradually of angle of elevation alpha angle, the acute angle α ' that sunlight direct projection direction and bioreactor are effectively generated between cultivation face diminishes gradually, namely vertical shadow length can be made to be adjusted to L ' by L after adjustment; In this adjustment process, in perpendicular in the diagram, the angle γ generated between sunlight direct projection direction and ground is changeless, the vertical direction length of side of bioreactor is fixing, if the bioreactor vertical direction length of side is L "; according to leg-of-mutton sine; L '/sin α '=L "/sin γ, owing to being fixed value on the right side of equation, therefore when α ' diminishes gradually, L ' also will diminish gradually, and namely the sunlight vertical shadow that generates after projecting bioreactor is long also will shorten gradually.When sunlight projects the spacing that the vertical shadow produced after bioreactor 1 grows up between this adjacent bioreactor base of vertical shadow length direction, can make, without direct sunlight light leakage phenomena, effectively can improve light utilization efficiency; During the spacing just in time equaled between the adjacent bioreactor 1 of this vertical shadow length direction when the vertical shadow produced after sunlight projects bioreactor 1 is long, the direct sunlight that can make is both without sunlight light leakage phenomena, unobstructed shade 6 between the adjacent bioreactor 1 made again, ensures the even light in each effective cultivation face of bioreactor 1.
In the present embodiment, the automatic adjustment of the angle of elevation alpha in the effective cultivation face to bioreactor 1 can be realized, but need to determine effective sun altitude and effective position angle.First, the actual value of sun altitude and azimuths of the sun can be determined by location longitude and latitude and time; Or utilize sun follower to measure the actual value of sun altitude and azimuths of the sun in real time.Then, measure the angle between bioreactor 1 and warp, obtain effective azimuths of the sun; And the angle measured between ground, bioreactor 1 place and horizontal plane, obtain effective sun altitude.Moreover, by effective sun altitude and effective position angle typing Controlling System; Finally, according to the angle of elevation alpha in not automatic effective cultivation face of the bioreactor 1 in adjustment corresponding moment in the same time.

In the present embodiment, the automatic adjustment of the azimuthal angle beta in the effective cultivation face to bioreactor 1 can be realized, but need azimuthal and effective sun altitude to determine.First, the actual value of sun altitude and azimuths of the sun can be determined by location longitude and latitude and time; Or utilize sun follower to measure the actual value of sun altitude and azimuths of the sun in real time.Then, measure the angle between ground, bioreactor 1 place and horizontal plane, obtain effective sun altitude.Moreover, by position angle and effective sun altitude typing Controlling System; Finally, according to the azimuthal angle beta in not automatic effective cultivation face of the bioreactor 1 in adjustment corresponding moment in the same time.
In the present embodiment, to the adjustment of the azimuthal angle beta in effective cultivation face of bioreactor 1, each bioreactor 1 or the multiple bioreactor 1 of interlock adjustment can be adjusted separately.
In addition, along with sun altitude and azimuthal change, the azimuthal angle beta in effective cultivation face of bioreactor 1 can be adjusted in real time, also can adjust the azimuthal angle beta in effective cultivation face of bioreactor 1 at a certain fixed time (such as: high noon) or multiple fixed time.Wherein, adjust in the azimuthal angle beta of certain one or more fixed time to effective cultivation face of bioreactor 1, energy when workload, saving rotation bioreactor 1 can be reduced.
In the present embodiment, when the light intensity on the effective cultivation face being radiated at bioreactor 1 is less than certain predetermined Intensity threshold, the azimuthal angle beta in effective cultivation face of adjustment bioreactor 1, the long spacing be not less than between the adjacent bioreactor 1 of this vertical shadow length direction of the vertical shadow produced after making sunlight project bioreactor 1, without sunlight direct projection (as the straight of the sunlight in Fig. 1 shines light leak ground 5) on ground now between adjacent bioreactor 1, its luminous energy free of losses.Especially, when the light intensity on the effective cultivation face being radiated at bioreactor 1 equals certain predetermined Intensity threshold, the azimuthal angle beta in effective cultivation face of adjustment bioreactor 1, the long spacing just in time equaled between the adjacent bioreactor 1 of this vertical shadow length direction of the vertical shadow produced after making sunlight project bioreactor 1, namely the shade that produces by solar light irradiation of the upper limb in effective cultivation face of bioreactor 1 is just at the lower rim in effective cultivation face of its adjacent bioreactor 1, unobstructed (as in Fig. 2 between effective cultivation face of i.e. adjacent bioreactor 1, because blocking of adjacent bioreactor 1 formed blocks shade 6), now not only there is no the optical energy loss of directing light, and on effective cultivation face of whole bioreactor 1 in uniform light, light splitting is good, further ensure the utilization ratio of overall light.
