Column coupling pyramid tube photoreactor, application and cultivation method

Abstract

The invention provides a column type and pyramid-tube type coupled photoproduction reactor, an application and a culture method. The photoproduction reactor comprises a column type reactor and a pyramid tube type reactor; the pyramid tube type reactor comprises at least two layers of reaction rings, layered inflow collecting pipes and layered outflow collecting pipes, wherein the at least two layers of reaction rings are accumulated sequentially from bottom to top, and the layered inflow collecting pipes and the layered outflow collecting pipes are separately led out of different positions of the reaction rings; the layered inflow collecting pipes and the layered outflow collecting pipes are separately connected with an outflow port and an inflow port of the column type reactor through a total inflow collecting pipe and a total outflow collecting pipe. According to the photoproduction reactor, the pyramid tube type reactor can be used for effectively eliminating a light shielding effect among pipelines and has the advantages of short tube pass, low resistance and high circulating flow speed; meanwhile, the pyramid tube type reactor is coupled with the column type reactor, so that gas exchange can also be taken into account, and the defect of the traditional tube type reactors that dissolved oxygen is difficult to release is eliminated. Through inside and outside combined light supplying, the photosynthesis can be further strengthened; in addition, large-scale circulation also contributes to contribute to the strengthening of a mass transfer process.

Description

technical field [0001] The invention belongs to the field of biochemical industry, and relates to a column-type coupled pyramid tube-type photogenerated reactor, an application and a cultivation method. Background technique [0002] Microalgae can convert CO through photosynthesis 2 And water is converted into various organic compounds (such as pigments, proteins, amino acids, vitamins and fatty acids, polysaccharides, etc.) that we need in life. Due to the high efficiency of light utilization by algae and the rapid and efficient absorption of nutrients from the surrounding environment (such as CO 2 , nitrogen, phosphorus, etc.) and the ability to transform into organic compounds, making algae a huge economic potential to solve food agriculture and energy crises in the future. At the same time, algae farming has a significant effect on CO 2 It is of great significance to improve the ecological environment such as fixing and sewage treatment. Although algae have high envi...
