Algae culture system

Abstract

The invention relates to an algae culture system, and the system comprises a culture reactor, and a control device, a water supply unit, an air supply unit, a cooling unit, a nutrient solution unit, an algae seed unit, a steam supply unit and a harvesting unit which are connected with the culture reactor; the water supply unit is connected with the breeding reactor through three parallel pipelines and is used for providing pure water, disinfectant fluid and cleaning water respectively; the air supply unit comprises an air module and a carbon dioxide module; a cooling water machine of the cooling unit provides cooling water for the breeding reactor; the algae seed unit and the nutrient solution unit respectively provide an algae seed source and a nutrient solution required by algae culture to the culture reactor; the harvesting unit is used for receiving the cultured algae liquid of the culture reactor and obtaining solid algae cells through a centrifugal machine; the steam supply unit provides high-temperature steam for the breeding reactor for disinfection and sterilization; the control device is in communication connection with and controls the breeding reactor, the water supply unit, the air supply unit, the cooling unit, the nutrient solution unit, the algae seed unit, the steam supply unit and the harvesting unit.

Description

technical field [0001] The invention belongs to the technical field of algae cultivation equipment, and in particular relates to an algae cultivation system. Background technique [0002] Haematococcus pluvialis is a single-celled green algae, the cells are oval or oval, and the cell size ranges from 4 microns to about 30-80 microns, sometimes even larger; the cells have two flagella for promoting cell freedom Swimming; there is a gap between the cell wall and the protoplast, which is filled with gelatinous substances, and the cell wall and the protoplast are connected by the cytoplasm; vegetative reproduction is cell division, forming 2, 4, 8, 16, 32 or even more daughter cells. [0003] Haematococcus pluvialis in the growth and proliferation stage has green cells; when environmental conditions change unfavorable to its growth, such as nitrogen deficiency, phosphorus deficiency or under the condition of strong light energy, the cell growth of Haematococcus pluvialis becomes...

AI Technical Summary

Problems solved by technology

The disadvantages of the raceway culture reactor are that the pipe wall is easily adhered by algae cells, resulting in decreased light transmittance, unstable temperature, and difficulty in cleaning during the cultivation period, and the low population density during the algae cultivation process makes it impossible to achieve large-scale algae raceway cultivation. production, and the yield of astaxanthin per unit area is low

The inner space of the tower kettle culture reactor is relatively large, and a large population density of algae can be obtained. However, in a large culture space, it is difficult to control the culture conditions to be uniform in all spatial positions, resulting in the population density of algae in the reactor. Inhomogeneity, unable to coordinate the overall cultivation progress of algae, affecting the overall astaxanthin production of the reactor
