Embodiment 1

[0022] Such as figure 1 As shown, it is a schematic structural diagram of the algae reaction control system in Embodiment 1 of the present invention. The algae reaction control system in this embodiment adopts a layered distributed control structure, including a general controller 11 and multiple control subsystems 12, wherein , each group of control subsystems 12 includes a sub-controller 13 and a reactor 14 . The working process of each component in the system is as follows:

[0023] The master controller 11 is used to determine at least one environmental parameter required for the growth of the algae, the corresponding range value of each environmental parameter according to the pre-saved information about the algae cultivated in each reactor 14, and correspond the environmental parameters of the algae to The range value is sent to the sub-controller 13 of the control subsystem where the reactor 14 of the algae is cultivated; the sub-controller 13 is used to detect the env...

Embodiment 2

[0032] The second embodiment of the present invention is received. One of the environmental parameters is the temperature of the reaction solution as an example to illustrate the monitoring of the algae environment in the reactor 14 by the sub-controller 13 . Such as figure 2 As shown, in a group of control subsystems 12, sub-controllers 13, reactors 14, and various sensors and actuators interact with each other to complete the structural schematic diagram of temperature monitoring, assuming that the involved sub-controllers 13 and reactors 14 are devices belonging to the same control subsystem 12.

[0033] The reaction solution temperature control process is described below:

[0034] Since algae have an optimal growth temperature, the optimal growth temperature of different algae may be different, therefore, the total controller 11 should determine the corresponding ideal reaction solution temperature and the corresponding range value of the reaction solution temperature ac...

Embodiment 3

[0048] In the third embodiment of the present invention, one of the environmental parameters received is the pH of the reaction solution and the dissolved oxygen of the reaction solution as an example to illustrate the monitoring of the algae environment in the reactor 14 by the sub-controller 13 . Such as image 3 As shown, in a group of control subsystems 12, sub-controllers 13, reactors 14, various sensors, and actuators work interactively to complete the monitoring of pH and dissolved oxygen. It is assumed that the involved sub-controllers 13 and the reactor 14 are devices belonging to the same control subsystem 12 .

[0049] The pH value (i.e. pH) and the dissolved oxygen concentration (dissolved oxygen) of the culture solution are one of the important factors affecting the growth of algae. By passing into the reactor 14 acid-base substances to adjust the pH value, the reactor 14 The pH of the reaction solution meets the requirements of algae cultivation. In addition, s...

Abstract

The invention discloses a system and a method for controlling reaction of alga. By adopting a layering gathering-scattering type control structure, a master controller performs unified configuration of the environmental parameter for growth of alga required by a plurality of sub-controllers in the system and transmits the environmental parameter of the alga to the sub-controller corresponding to areactor for cultivating the alga; and the sub-controller monitors the environment of the reactor according to the received environmental parameter to ensure that the environmental parameter of the reactor is in a state suitable for growth of the alga. Accordingly, a great amount of alga cultivating sub-controllers are monitored to make the large-scale industrial production possible.

Description

technical field [0001] The invention relates to algae cultivation technology, in particular to an algae reaction control system and method. Background technique [0002] The growth and reproduction of photosynthetic microorganisms or plant cells, especially microalgae and cyanobacteria (referred to as algae), is mainly through photosynthesis, using light energy (such as sunlight and artificial lighting) to convert water and carbon dioxide into pigments, proteins, fatty acids, sugars and secondary metabolites and other high-value organic compounds. Algae exhibit a stronger growth potential than higher plants due to their extremely high light use efficiency and nutrient use efficiency. [0003] Algae culture devices can be mainly divided into open pool systems and closed / semi-closed reactor systems. Due to problems such as lack of temperature control, long optical path and uneven mixing, the open cell system leads to low overall productivity and is prone to bacterial contami...
