Abstract

The present application discloses a haematococcus pluvialis culture system utilizing power plant flue gas. The system comprises the following parts: a horizontal tubular photobioreactor; a circulatingbuffer tank; a conveying device; an aerator, which is disposed on one end of the horizontal tubular photobioreactor; a power plant flue gas pipeline, which is connected to the aerator through a pipeline; and a first gas mass flowmeter, which is disposed on the pipeline connecting the power plant flue gas pipeline to the aerator, and is used for regulating an input flow of the power plant flue gas. By setting the aerator, the system can realize continuous dispersion aeration, not only ensures sufficient carbon source for the haematococcus pluvialis, but also reduces the demand for high concentration CO2 of the haematococcus pluvialis to 15% or below. Therefore, while using the power source flue gas to provide a carbon source, the system reduces flue gas CO2 emission, and achieves the effect of energy saving and emission reduction. By real-time monitoring and timely gas flow regulation, the system can ensure the stability of the acid-base environment of the haematococcus pluvialis culture, promote the growth of the haematococcus pluvialis and increase the astaxanthin content.

Description

technical field

[0001] The invention relates to the field of microalgae cultivation, in particular to a Haematococcus pluvialis cultivation system utilizing power plant flue gas. Background technique

[0002] In the industrial cultivation process of Haematococcus pluvialis, the red stage of Haematococcus pluvialis is often cultivated in a horizontal tubular photobioreactor, and the aeration method is concentrated and indirect aeration, that is, the algae of Haematococcus pluvialis The liquid is aerated in the liquid storage tank, and then input into the horizontal tube reactor without aeration device, receiving light to induce the synthesis of astaxanthin, and recirculating back to the liquid storage tank to supplement the carbon source. Haematococcus pluvialis not only has the problem of insufficient carbon source due to consumption in the horizontal tube photobioreactor, but also may agglomerate and settle or adhere to the wall. In addition, Haematococcus pluvialis under ...
