Abstract

The invention discloses a carbon sequestration and supplementation reactor for gas circulation type microalgae cultivation. The carbon sequestration and supplementation reactor comprises a shell, an inner sleeve, a liquid inlet pipe, a gas inlet pipe, a fixed support and a gas circulation pipeline. The fixing support is installed in the shell, and the bottom end of the fixing support communicateswith the bottom end in the shell. The inner sleeve is fixed at the top end of the fixing support, the inlet end of the liquid inlet pipe extends out of the shell, and the outlet end extends into the inner sleeve; one end of the air inlet pipe communicates with the bottom of the inner sleeve, and the other end communicates with an air supply device; one end of the gas circulation pipeline is communicated with the top end of the shell, and the other end is communicated with the gas supply device. The carbon sequestration and supplementation reactor also comprises a liquid outlet pipeline which is communicated with the bottom end of the shell. According to the carbon sequestration and supplementation reactor, the CO2 is fully dissolved in the liquid, and the carbon sequestration and supplement efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of microalgae cultivation, and more specifically relates to a carbon-fixing and carbon-supplementing reactor for gas-circulation microalgae cultivation. Background technique [0002] Microalgae are a type of autotrophic organisms that are widely distributed on land and in the ocean, are rich in nutrients, and have high photosynthetic utilization. The polysaccharides, proteins, and pigments produced by the metabolism of microalgae cells make them have good development prospects in the fields of food, medicine, genetic engineering, and liquid fuels. As a photoautotrophic organism, microalgae can use sunlight energy to fix carbon dioxide through photosynthesis and synthesize organic substances needed for their own metabolism. However, photosynthetic autotrophy of microalgae cannot directly utilize the gas CO 2 , but utilize the HCO 3 - Soluble CO in the form of 2 . If food-grade solid sodium bicarbonate i...
