Problems solved by technology
The closed culture device is too complicated, and the cost and applicability issues have always been the "bottleneck" restricting the transformation of Unicellular algae culture to productive culture
In an open system, Unicellular algae are not uniformly distributed in the water body, and are easy to settle, and cannot make full use of sunlight and gas exchange, so mechanical stirring is necessary
The existing flat-plate and tube-type photobioreactors in this field are too complicated, and they do not have the characteristics of convenience, simplicity, effectiveness and low cost when cultivating unicellular algae

Embodiment 1
[0029] Embodiment 1: using low density polyethylene as material.
[0030] The whole reactor is made of low-density polyethylene material with light transmittance above 75% by the above-mentioned method. The columnar body 2 has an inner diameter of 150mm and a height of 1200mm, wherein the growth part of the unicellular algae 7 has a height of 900mm, the height of the buffer part 8 is 300mm, the radius of the bottom surface of the inverted conical airlift part 1 is 150mm, and the height is 90mm, and the top of the buffer part 8 is closed. The longitudinal dimension of the suspension structure is 600mm, and the inner diameter is 150mm. Because low-density polyethylene has good toughness, the suspension structure 3 can be an extension of the top of the columnar body 2, that is, the part that grows to a height of 1200 mm can be used for suspension by knotting.
[0031] The inverted conical top of the airlift part 1 is provided with an inflatable tube 4, and the inflatable tube 4 is...

Abstract
The invention relates to a film hanging bag type unicellular algae photo-bioreactor and a manufacturing method thereof. The reactor comprises a hollow transparent cylindrical body, wherein the bottom of the cylindrical body is provided with an obconical air-lift part, the top of the cylindrical body is closed and provided with a suspension structure, the bottom of the air-lift part is connected with an inflatable pipe, the outer side surface of the cylindrical body is sequentially provided with a feed liquid inlet pipe and an algae liquid discharge pipe from the top down, a growth part is arranged between the air-lift part and the algae liquid discharge pipe, and a buffering part is arranged between the feed liquid inlet pipe and the algae liquid discharge pipe. During manufacture, the lower end of a cylindrical film can be made into the obconical air-lift part, the top end of the cylindrical film is closed, and the side surface of the cylindrical film is sequentially provided with the inflatable pipe, the feed liquid inlet pipe and the algae liquid discharge pipe. The invention has the advantages of low investment, high success ratio, convenience for installation and the like; in addition, the film hanging bag type unicellular algae photo-bioreactor balances the functionality, the production performance, the cost and the operation, thus the small-scale large-area cultivation can be carried out, and the productive cultivation can also be realized.
Description
technical field [0001] The invention relates to a photobioreactor and a manufacturing method thereof, in particular to a film-hanging-bag-type unicellular algae photobioreactor and a manufacturing method thereof, which are suitable for production as a closed reactor for cultivating unicellular algae. Background technique [0002] In the three-stage productive culture stage of Monocystis, there are two ways of open culture and closed culture. Open culture includes traditional open pool culture and open track pool culture. Traditional open pools mainly include fiberglass tanks, earthen pools, cement pools, etc.; open raceway pools refer to the race-way photobioreactor (Race-way Photobioreactor) designed by Oswald, which is currently popular in production. Closed culture photobioreactors include plate type and tube type, but at present they are only in the stage of small test or pilot test, and there are no reports of formal application in production. [0003] The problems an...
