Problems solved by technology

On the other hand, when the bubbles are generated at the bottom of the reactor and float up in the microalgae suspension, the bubbles at adjacent positions are prone to coalesce, which makes the volume of the bubbles larger and the specific surface area smaller, making the gas-liquid mass transfer effect become worse

Abstract

The invention discloses a composite reinforced microalgae photobioreactor based on hollow light pipes. The photobioreactor comprises a reactor roof, stainless steel coiled pipes, the hollow light pipes, a gas distributor, a reactor bottom plate, a reactor main body, a gas-liquid separation device and an online pH, temperature and DO (dissolved oxygen) monitoring device, wherein the stainless steel coiled pipes are arranged at left and right inside the reactor main body, respectively; the gas distributor is an annular pipe penetrating through the bottom in the reactor main body, and a plurality of air outlets are formed in the gas distributor inside the reactor main body; a plurality of hollow light pipes are uniformly arranged in the reactor main body; the gas-liquid separation device is arranged on the reactor roof; the online pH, temperature and DO monitoring device is arranged inside the reactor main body. The reactor has the main advantage of coupling reinforcing of light transfer and CO2 mass transfer and reinforcing of a microalgae cell photo-biochemical reaction together, so that the comprehensive performance of the microalgae photobioreactor can be improved.

Description

technical field [0001] The invention relates to a photobioreactor for cultivating photosynthetic microalgae, in particular to a composite enhanced microalgae photobioreactor based on a hollow light pipe. Background technique [0002] Global warming and the shortage of fossil energy are two major problems facing mankind in the 21st century. Global warming is mainly caused by a large amount of greenhouse gas emissions. There are many types of greenhouse gases and different types of greenhouse gases contribute differently to the greenhouse effect. Carbon dioxide is considered to be the most important greenhouse gas, and its contribution to the greenhouse effect is the largest. , so reducing carbon dioxide emissions can effectively alleviate the trend of global warming. The shortage of fossil energy is mainly caused by the excessive consumption of fossil energy during the development of human society. The vigorous development of renewable energy can effectively alleviate the re...
