Circulating temperature-controlled microalgae illumination culture device

Abstract

The invention provides a circulating temperature-controlled microalgae illumination culture device, which comprises a culture system and a temperature control system. The culture system comprises an illumination box (1) and a culture vessel (16), side light sources (2) are arranged on the periphery of the illumination box (1), and universal wheels (3) are arranged below the illumination box (1); the culture vessel (16) is provided with a culture vessel cover (17), a central light source (18) and an air pump (19), and mixed gas is introduced through an air inlet pipe (20) in the microalgae culture process. The temperature control system comprises a control box (4), a water bath box (7) and a heat exchanger (14); the control box is provided with a display instrument (5) and a function switch (6), and the temperature of circulating water is controlled through a heater (8) and a temperature sensor (9); and a spiral tube type heat exchanger (14) is arranged and controlled in the culture vessel (16). The water bath box (7) and the heat exchanger (14) are connected through a water outlet pipe (11) of the water bath box, a circulating water pump (12), a water inlet pipe (13) of the heat exchanger and a water outlet pipe (15) of the heat exchanger to form a circulating pipeline.

Description

technical field [0001] The invention relates to the technical field of microalgae cultivation, in particular to an illumination and water bath cycle temperature control microalgae cultivation device, that is, a cycle temperature control microalgae illumination cultivation device. Background technique [0002] Microalgae are a class of ancient lower cryptogamous plants that are self-supporting through photosynthesis, and there are many kinds. It has a wide range of distribution, strong ability to adapt to the environment, and short growth cycle. The ability of microalgae to fix carbon dioxide is about 10 to 50 times that of terrestrial plants. It is the oldest primary producer on the earth, and it is also a natural reaction for efficient photobiological conversion. device. Microalgae have unique genetic information, biochemical components, metabolic pathways and metabolites. Algae cells contain a large number of nutrients such as polysaccharides, lipids, and proteins, which ...

Problems solved by technology

At present, most of the technical development in the field of microalgae cultivation is concentrated on normal temperature algae cultivation, and there are still several problems in the microalgae cultivation system, especially the thermophilic algae cultivation system: 1. The cost of temperature control is high; the growth temperature of normal temperature algae is between 25~30°C During the period, the temperature of water at room temperature in northern my country is low, and it needs to be cultivated in a constant temperature greenhouse or incubator, which consumes a lot of energy; 2. In the process of large-scale cultivation, the light intensity is insufficient. In the process of expanding cultivation, light control is one of the difficulties in cultivation; 3. The common large-scale cultivation system of pipeline is high in maintenance cost, difficult to clean, and easy to cause pollution
