Problems solved by technology

However, the setting of spoiler baffles increases the flow resistance and reduces the flow velocity of the algae liquid, so it is necessary to develop a new reactor structure to increase the flash frequency to promote the growth of microalgae and carbon sequestration.

Abstract

The invention relates to a biomass energy utilization technique, and aims to provide a pipe and pond combined type gleaming bioreactor system and a microalgae growth carbon consolidating method. The system comprises racetrack pond reactors for culturing microalgae, wherein a plurality of horizontal transverse pipes made from a translucent material are arranged above the corresponding racetrack pond reactor in parallel, and are mutually perpendicular to the length direction of the corresponding racetrack pond reactor; the ends of the adjacent horizontal transverse pipes are connected through abent pipe to form a perforated horizontal transverse pipe reactor; an outlet end of the horizontal transverse pipe reactor is sequentially connected with the racetrack pond reactors and a CO2 dissolver through a pipeline, and the outlet end of the CO2 dissolver is sequentially connected with a centrifugal pump and an inlet end of the horizontal transverse pipe reactor through a pipeline; and an air distributor is arranged in the CO2 dissolver and is connected to a CO2 air source through a pipeline. The pipe and pond combined type gleaming bioreactor system can improve the distribution of a light region and a dark region of the surfaces of algae liquid in a racetrack pond, the gleaming effect when microalgae cells flow is notably reinforced, the gleaming frequency when the microalgae cellsmove in the racetrack pond is increased, and promotion of growth and carbon consolidation by microalgae photosynthesis is facilitated.

Description

technical field [0001] The invention relates to biomass energy utilization technology, in particular to a tube-pool combined flash bioreactor system and a method for microalgae growth and carbon fixation. Background technique [0002] Due to their fast growth rate, high light energy utilization efficiency, and high economic value of biomass, microalgae have become CO2 in flue gas. 2 Frontier research hotspots in the fields of emission reduction and new energy development. Make full use of microalgae to capture CO in the flue gas of coal-fired power plants, coal chemical plants, industrial furnaces, etc. 2 , while reducing the cost of raw materials for microalgae production, biomass rich in high-value active ingredients can also be obtained. As the most successful commercial cultivation model in the microalgae cultivation industry, the raceway pond reactor has been widely used at home and abroad because of its simple equipment, process operation and easy scale-up.
