A multifunctional device for algae production

Abstract

The present application discloses a multifunctional device for algae production, which is used for algae cultivation in a pipe-type photobioreactor comprising one or more photobioreactor tubes, each reaction tube having a branched liquid inlet pipe and a branched liquid outlet pipe , each branch liquid outlet pipe leads to the external discharge device through the main liquid outlet pipe, and each branch liquid inlet pipe is provided with a joint that can be disconnected and reconnected to the branch liquid inlet pipe, and is connected to the fluid supply via the main liquid inlet pipe. source fluid communication, the device includes a harvesting and cleaning member that keeps the different fluids ahead and behind it isolated from each other while moving within said photobioreactor tube, the harvesting and cleaning member can be placed into a branch inlet pipe at a joint , and enter the corresponding photobioreactor tube and move forward under the thrust of the fluid driven by the power device, and be discharged from the device through each branch liquid outlet pipe and the total liquid outlet pipe. This equipment can be used for algae liquid harvesting, cultivation equipment cleaning and algae liquid injection.

Description

technical field [0001] This application relates to a multifunctional device for algae production, especially a device that integrates algae liquid or cell inoculation, algae harvesting, equipment disinfection and cleaning, and is mainly used for algae cultivation using pipeline photobioreactors situation. Background technique [0002] Pipeline photobioreactor is a common device for cultivating photobiological organisms such as microalgae. The photobioreactor tubes of this pipe-type photobioreactor are usually installed horizontally and have no slope, so that after the completion of microalgae cultivation, it takes a long time to harvest the algae liquid by gravity, and the algae liquid is not harvested completely. Liquid will accumulate in the pipes. In addition, since the self-flow harvesting method of the algae liquid is not pressure-driven and has no flushing effect, the algae liquid stays for a long time, resulting in a considerable part of the algae liquid staying on ...

AI Technical Summary

Problems solved by technology

Then add water to dilute the remaining liquid with chemical reagents, and finally discharge the diluted chemical reagent solution, the process is very complicated

[0004] All in all, for the current pipeline photobioreactor, the harvesting process of the algae liquid and the cleaning process of the algae cultivation device require a lot of manpower and material resources, which is very unfavorable for the large-scale cultivation of microalgae.
