specific Embodiment approach 1

[0019] Specific implementation mode one: combine figure 1 , figure 2 As shown, the present embodiment is a device for microalgae adherent culture and liquid immersion culture conversion, which includes a concentrator 1, a connecting pipe 2, a drip irrigation pipe 3, a groove plate 4, a rotatable support 5, and a collection box 6 ; The placement direction of the grooved plate 4 is at an angle of 5-15° with the horizontal plane; 8. The upper surface of the flexible liquid-permeable material plate 7 has protruding structural units 9 on the surface, and the rows extending in the transverse direction and the columns extending in the longitudinal direction constitute an array of structural units; the transverse of the structural units 9 The cross-section is circular, square, rectangular, elliptical, triangular or rhombus; the structural units 9 are arranged at equal intervals in the same row or the spacing is increased successively; the row spacing between adjacent rows of the str...

specific Embodiment approach 2

[0020] Embodiment 2: This embodiment differs from Embodiment 1 in that the concentrated algae liquid flows out from the outlet of the concentrator 1, and the operating pressure of the concentrator 1 is 0.10-0.20 MPa. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0021] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that the drip irrigation pipe 3 is responsible for spreading the algae liquid on the upper surface of the groove plate 4, so as to realize the liquid submerged culture state to the adherent type The transition of the cultivation state, the nominal diameter of the drip irrigation pipe 3 is 12-16mm. Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention provides a device for converting microalgae adherent culture and liquid submerged culture, and relates to a device for culturing microalgae. The problem that multiple and repeated conversions between the liquid submerged culture and the adherent culture cannot be achieved at present is mainly solved. The device comprises a concentrator, a communicating pipe, a drip irrigation pipe, a groove plate, a rotatable support and a collecting box. The device for converting the microalgae adherent culture and liquid submerged culture has the advantages that the cost is low, the operation is easy, and the maintenance is easy; the light decay phenomenon which is caused by mutual shielding of algae and exists in submerged culture is solved, and meanwhile the defects that the solubility of CO2 in a water body is lower, and the CO2 absorption efficiency is limited are overcome simultaneously; the conversion between the microalgae adherent culture and liquid submerged culture is achieved, the microalgae high carbon sequestration efficiency is achieved, and rapid and high-density culture is achieved simultaneously; the growth rate of microalgae is effectively improved, the culture cost of the microalgae is reduced, when the microalgae are cultured to reach the maximum biomass, the processes can reappear by placing the microalgae in the concentrator, and the purpose for converting repeatedly for multiple times is achieved.

Description

technical field [0001] The invention relates to a device for cultivating microalgae. Background technique [0002] Microalgae are low-level aquatic organisms capable of oxygen release and photosynthesis. They have simple structure, rapid reproduction, high utilization rate of solar energy, ability to reduce greenhouse gas (carbon dioxide), and strong adaptability to the environment. The third generation biomass energy raw material. [0003] The culture of microalgae is usually submerged in liquid, which consumes a lot of water, and there is light attenuation in the water body and CO 2 The low solubility in water and other issues limit the carbon fixation efficiency and light absorption efficiency of chlorella. Adherent culture utilizes the adherent characteristics of algae cells to reduce water consumption and make CO 2 Fully in contact with algal cells, CO 2 The utilization rate of microalgae is significantly improved, and the transmission of light does not require a lo...
