Full-plastic airtight modularized airlift light biological reactor

Abstract

The invention relates to a full-plastic airtight modularized airlift light biological reactor in the biological field, which is characterized in that a full-plastic transparent barrel part (1) uses adhesives, a full-plastic transparent base (3) is fixed to form a container, and a drain hole is arranged on the full-plastic transparent base (3) and connected with a full-plastic water valve to form a collection water outlet (17). A full-plastic transparent top cover (2) is firmly connected with the full-plastic transparent barrel part (1) through a full-plastic closed bolt (14) and a full-plastic sealing part (15) so as to form a full-plastic airtight light biological reaction tank body. The full-plastic airtight modularized airlift light biological reactor solves problems that complex coastal environment of our country, large changes of sea water temperature and large storm waves bring difficulty to microalgae outdoor breeding, light cannot penetrate through water when a planar culture pond is deep by adopting the planar culture pond mode, microalgae at the bottom of the planar culture pond cannot absorb enough light and breeding output efficiency caused by insufficient circularly stirring is reduced .

Description

technical field [0001] The invention relates to a bioreactor used for culturing microalgae in the biological field, in particular to an all-plastic airtight modular airlift photobioreactor. Background technique [0002] Among the various greenhouse gases generated by the massive consumption of fossil fuels in the world, CO 2 The total amount of emissions is the largest, and its impact is severe. Therefore, under the impact of global climate change and the pressure of environmental protection and ecological orientation, promote the reduction of CO in the atmospheric environment 2 Content has become a top priority for all countries in the world, and the sustainable proposition of energy conservation, carbon reduction and the development of a green ecological model has become a common development goal for all walks of life. [0003] At present, various carbon reduction methods in science and engineering technology, including physical adsorption, chemical absorption, low-tempe...

AI Technical Summary

Problems solved by technology

[0009] Nowadays, microalgae mostly use open planar culture ponds as an outdoor culture mode, which requires a large area of ​​land to obtain sufficient sunlight. However, when the depth of the planar culture pond is deep, the light cannot penetrate. Therefore, the bottom of the planar culture pond The microalgae cannot absorb enough light and are not fully circulated and stirred, which reduces the efficiency of the culture output. At the same time, the outdoor flat culture pond mode also has the risk of microalgae being easily cross-contaminated by other algae or microorganisms. These two factors Invisibly also increased operating costs
