Ventilation and temperature control system for algae cultivation and algae cultivation system

Abstract

The invention relates to the technical field of biology, in particular to a ventilation and temperature control system for algae culture and an algae culture system. The ventilation and temperature control system comprises a heat-preserving water pond, a hot water generation unit, a cold water supply unit, a controller and a temperature sensor, wherein the temperature sensor is placed in the heat-preserving water pond and can monitor the temperature of water in the heat-preserving water pond in real time, a gas-liquid heat exchanger is immersed in the heat-preserving water pond, one end of the gas-liquid heat exchanger is communicated with ventilation equipment, the other end is connected with a bioreactor, the temperature of the heat-preserving water pond is kept to be proper to realize heat exchange with the gas-liquid heat exchanger to transmit heat to gas of the gas-liquid heat exchanger, the gas-liquid heat exchanger is communicated with a photobioreactor, air or carbon dioxide fed into the photobioreactor can have temperature facilitating microalgae growth, and after the air or carbon dioxide is fed into the photobioreactor, a suitable environment can be provided for microalgae growth.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a ventilation and temperature control system and an algae cultivation system for algae cultivation. Background technique [0002] Microalgae are a type of phytoplankton that grow in a wide variety of water bodies and are widely distributed and individuals are generally smaller than 2mm. Their cells are like sunlight-driven organic matter factories. Through their efficient photosynthesis, they use light energy to absorb CO 2 and H 2 O, convert them into chemical energy such as carbohydrates, proteins, fats, etc., and release O 2 . [0003] At present, "microalgae high-efficiency large-scale cultivation technology" is one of the cores of microalgae biotechnology. Usually, the algal liquid is located in the photobioreactor, and air or carbon dioxide is fed into the photobioreactor through the aeration device, and there is an aeration pipe between the photobioreactor and the aeration ...
