Industrial waste gas treatment device for realizing carbon neutralization by utilizing microalgae

Abstract

The invention discloses an industrial waste gas treatment device for realizing carbon neutralization by utilizing microalgae, which comprises a microalgae culture container, the microalgae culture container is a narrow high flat type container, the height of the microalgae culture container is less than 0.2 m, the bottom surface of the microalgae culture container is parallel to the horizontal plane, and the area of the bottom surface is greater than 2m < 2 >; the top surface of the microalgae culture container is obliquely arranged relative to the horizontal plane, the projection of the microalgae culture container on the horizontal plane coincides with the bottom surface, and the top surface for light source incidence is made of a transparent material with preset light transmission performance; array micropores for introducing carbon dioxide are formed in the bottom surface and are connected with a carbon dioxide preparation chamber, the carbon dioxide preparation chamber is connected with a first pipeline, and the first pipeline is used for introducing carbon dioxide; the inclined top end of the top surface is connected with an exhaust port, the exhaust port is connected with an oxygen adsorption box loaded with an oxygen adsorbent through a second pipeline, and the oxygen adsorption box is connected to the first pipeline. The method can effectively improve the treatment efficiency of carbon dioxide in industrial waste gas by microalgae.

Description

technical field [0001] The invention relates to the field of carbon neutralization, in particular to an industrial waste gas treatment device utilizing microalgae to realize carbon neutrality. Background technique [0002] Carbon neutrality means that enterprises, groups or individuals calculate the total amount of greenhouse gas emissions directly or indirectly produced within a certain period of time, and offset their own carbon dioxide emissions through afforestation, energy conservation and emission reduction, etc., to achieve "Zero emissions" of carbon dioxide. In many industrial productions, a large amount of waste gas containing carbon dioxide will be produced, and direct emission will cause the greenhouse effect. Therefore, it is necessary to remove carbon dioxide from industrial waste gas, which is also an important means to achieve carbon neutrality. [0003] Commonly used industrial carbon dioxide waste gas treatment mainly includes three methods: physical landf...

AI Technical Summary

Problems solved by technology

However, the existing technology of using microalgae to process carbon dioxide is generally to pass carbon dioxide into the columnar culture container, and then carry out photosynthesis, which leads to: 1. Microalgae overlapping cannot get enough light, and the efficiency of photosynthesis decreases; Second, the concentration of carbon dioxide is getting lower and lower, resulting in a decrease in the efficiency of photosynthesis

Therefore, the existing technology is not efficient for the treatment of waste gas containing carbon dioxide
