Problems solved by technology
[0004] However, in the existing flat-plate photobioreactors, the commonly used partition structures are all staggered equal-length partitions. This arrangement makes the reaction between the feed liquid and the gas insufficient, and at the same time, waste feed liquid The processing is not convenient enough, and the device is not easy to clean. At the same time, the flow of gas and the circulation of material liquid may also cause unpredictable situations such as blockage of the device due to the inconvenience of processing. Therefore, it is urgent to provide a device that can overcome the above existing problems. Photoreactors with various defects in the production technology and process

Embodiment Construction
[0048] In order to better understand and illustrate the present invention, reference will be made to Figure 1-4 The present invention is further described in detail.
[0049] figure 1 is a schematic diagram of the overall structure of the photoreactor according to a preferred embodiment of the present invention. Such as figure 1As shown, the overall structure of the photoreactor is composed of three parts: a photoreactor main body 100 , a rotatable mechanical shaft 105 and a supporting base 200 . Wherein, the photoreactor main body 100 is composed of an air inlet 101, an air outlet 102, an inlet 103, an outlet 104, a short partition 106, a long partition 107, a gas distributor 108, two light-receiving surface panels 109, a top It consists of a frame 1101, a bottom frame 1102, a left frame 1103, a right frame 1104, and a sensor device connection port 111, the specific positions of which are shown in the figure.

The invention discloses a photoreactor, comprising a photoreactor body, a rotatable mechanical shaft and a supporting base. The photoreactor is characterized in that the photoreactor body comprises two light-receiving panels and borders; the bottom border of the photoreactor body is connected with the supporting base through the rotatable mechanical shaft; and a long clapboard and a plurality of short clapboards are arranged in parallel inside the photoreactor body, a photoreaction zone is laterally divided into a liquid ascending region and a liquid descending region by the long clapboard, and a gas distributor is arranged at the bottom of the liquid ascending region and is connected with an external gas inlet pipeline through a gas inlet. The photoreactor disclosed by the invention has the advantages of large reaction specific surface area, good air permeability, and good performance in mixing and circulating a culture solution, and is suitable for the large-scale culture of photosynthetic energy microorganisms.
Description
technical field [0001] The invention relates to a photoreactor and a method for cultivating microorganisms, in particular to a photobioreactor for cultivating photosynthetic microorganisms with partition structures of different lengths inside. Background technique [0002] Photoreactors are usually used in the industrial production of algae, photosynthetic bacteria, moss or other plant or microbial cell culture. These plants or microorganisms, especially photosynthetic microorganisms can use light energy to convert CO 2 It can be transformed into various organic substances with water, and has the characteristics of high photosynthesis efficiency, strong environmental adaptability, fast reproduction, short growth cycle, no occupation of cultivated land, large-scale, automatic control cultivation (production), etc. [0003] At present, there are mainly two types of photobioreactors for the cultivation of photosynthetic microorganisms: open and closed photobioreactors. Because...
