Dispersion optical-fiber type photo-bioreactor with inserted spiral band

Abstract

The invention discloses a dispersion optical-fiber type photo-bioreactor with an inserted spiral band. The photo-bioreactor comprises a top cover, an outer pipe, an inner pipe and a bottom cover. The outer pipe, the top cover and the bottom cover are provided with through holes, and the outer pipe wall is provided with a liquid inlet and a liquid outlet; and the top cover is arranged at the top of the outer pipe, and the bottom cover is arranged at the bottom of the outer pipe. The dispersion optical-fiber type photo-bioreactor is characterized in that a step is arranged at the top of the inner pipe which penetrates through the through hole of the top cover to be inserted into the through hole of the outer pipe and is limited by the step arranged at the top of the inner pipe; the spiral band which is arranged between the outer pipe and the inner pipe and encircled on the inner pipe enables a spiral upward channel to be formed in a microalgae culturing area between the inner pipe and the outer pipe; a sand core funnel is arranged in the through hole of the outer pipe below the bottom of the inner pipe, the lower portion of the sand core funnel penetrates through the through hole of the bottom cover, and a seal plug is sleeved on the lower portion of the sand core funnel and fixed in the through hole of the bottom cover; and an optical fiber core is inserted in the inner pipe.

Description

technical field [0001] The invention relates to a bioreactor, in particular to a diffuse optical fiber type photobioreactor inserted with a helical bond. Background technique [0002] In today's world, the economy is developing rapidly, and the problem of climate warming caused by human emissions of greenhouse gases is becoming more and more serious. Among greenhouse gases, CO2 contributes the most to the greenhouse effect. The concentration of carbon dioxide in the atmosphere has increased from 0.028% before the industrial revolution to 0.036% now. In the 20th century, the global average surface temperature has increased by 1.0°C, and the average ocean temperature has increased by 0.6°C. This climate anomaly will have serious impact on the human living environment. Irreversible and catastrophic consequences, such as increased desertification, reduced agricultural production, frequent occurrence of severe weather and reduction of forest area. Therefore, reducing CO2 emissi...
