Embodiment 1

[0077] The present invention provides a column coupling pyramid tube photogenerated reactor, please refer to figure 1 , which is a schematic diagram of the three-dimensional structure of the photogenerated reactor, including a column reactor 1 and a pyramid tube reactor 2 . figure 2 Shown is a side view of the pyramidal tube reactor.

[0078] Specifically, the column reactor 1 can be, but not limited to, cylindrical or polygonal, and at least a part of it is made of transparent material, such as plexiglass, so that light can penetrate into the column reactor and be utilized.

[0079] Concrete, described pyramid tube reactor 2 comprises:

[0080] At least two layers of reaction rings 201 accumulated sequentially from bottom to top; wherein, the circumference of the reaction ring located in the lower layer is greater than the circumference of the reaction ring located in the upper layer;

[0081] The stratified inflow manifold 202 and stratified outflow manifold 203 respectiv...

Embodiment 2

[0103] The present invention also provides an application of a photo-generated reactor, the photo-generated reactor adopts the column-type coupled pyramid tube-type photo-generated reactor described in Embodiment 1.

[0104] Specifically, the application may also be microbial cultivation, chemical reaction vessels, biological purification of environmental pollutants, etc. in the fields of biology, chemical engineering, and the environment.

[0105] As an example, the application is the use of the photoreactor for microalgae cultivation and CO 2 fixed.

Embodiment 3

[0107] The present invention also provides a culture method, please refer to Figure 8 , is shown as an operation flow chart of the culture method, comprising the following steps:

[0108] S1: will contain CO 2 The gas transported to the total inflow manifold of the pyramid tube reactor;

[0109] S2: Utilize the propelling effect of the air flow and the circulation pump to make the alga liquid in the total inflow manifold flow to the layered inflow manifold, and further flow into the reaction rings of each layer of the pyramid tube reactor, and the gas mix well;

[0110] S3: using at least one of natural light source and artificial light source as a light source to make the algae liquid carry out photosynthesis in the reaction ring under light conditions.

[0111] As an example, see Figure 9 , shows the pipeline connection diagram of the photoreactor used in the cultivation method of the present invention. As shown in the figure, the photogenerated reactor and circulatio...

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...
