Hanging-bag microalgae photoreactor and hanging-bag microalgae culture system

Abstract

The invention relates to a hanging-bag microalgae photoreactor and a hanging-bag microalgae culture system. The photoreactor and hanging-bag microalgae culture system comprises a reactor main body formed by a transparent film bag with the end part closed, wherein the interior space of the transparent film bag is partitioned into a plurality of space structures by at least one separating line which has non-continuous breakage sections. The hanging-bag microalgae culture system comprises at least one of the hanging-bag microalgae photoreactor. The hanging-bag microalgae photoreactor is good in light transmittance, prolongs the retention time of CO2 gas in water, and more facilitates absorption of the microalgae culture system to CO2 gas. The hanging-bag microalgae culture system has a simpler structure and low manufacture and use costs, and can meet the demand on closed culture of high-quality clean microalgae.

Description

technical field [0001] The invention relates to a hanging bag type microalgae photoreactor and a hanging bag type microalgae cultivation system, which is a device for carrying out photosynthetic microalgae cultivation by using a transparent film bag. Background technique [0002] Microalgae are able to use simple mineral nutrients to convert CO under photosynthesis (sunlight and artificial lighting) 2 And water is converted into various organic compounds (such as pigments, proteins, amino acids, vitamins and fatty acids, polysaccharides and minerals and other essential nutrients). 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, so that algae have the ability to solve food shortages, energy crises and CO 2 Huge economic potential for emission reductions. [0003] At present, there are ...

AI Technical Summary

Problems solved by technology

The above two existing patents are the transformation of the structure of the transverse isolation zone of the commonly used film culture bag at present. Compared with CN102086437A and the prior art, it solves the problems of light transmission and culture layering of the large-diameter single-column photoreactor, but its division The mode is divided from line to point, which are two extreme cases. The vertical isolation zone is consistent with the rising direction of the gas, which is not conducive to the horizontal stirring of the gas in the culture system. The point isolation is not ideal for solving the gas stirring and gas distribution of the culture.
