Bubble guide component, high-density microorganism culture device and applications

Abstract

The invention discloses a bubble guide component. The bubble guide component comprises at least two zigzag guide members arranged along guide plate. Each zigzag guide member comprises at least two guide plates which are up-down connected in the vertical direction. The guide plats are obliquely arranged relative to the horizontal plane. The oblique directions of any adjacent guide plates in the same zigzag guide member relative to the horizontal plane are opposite. A zigzag and rising channel is formed among any adjacent zigzag guide members. The projections of any guide plate of the zigzag guide member and the closest guide plate of the adjacent zigzag guide member in the horizontal plane are overlapped partially. The bubble guide component increases the area of bubble guide per unit volume greatly, realizes modular assembly, and has strong adaptability. The invention also discloses a high-density microorganism culture device which can realize large-scale production and applications in waste gas treatment and microalgae culture.

Description

technical field [0001] The invention relates to the technical field of microorganism cultivation, in particular to an air bubble guide assembly, a high-density microorganism cultivation device and the application of the device in microorganism cultivation and waste gas treatment. Background technique [0002] The main cause of modern air pollution is the excessive discharge of industrial waste gas from coal-burning, oil-burning and gas-burning industrial operations and exhaust gas from various oil-burning transportation vehicles. Its main components include harmful carbon dioxide, nitrogen oxides, sulfur oxides and Carbon monoxide and harmless nitrogen and water vapour. Excessive carbon dioxide in the atmosphere causes the greenhouse effect and can acidify seawater, which is the main cause of the deterioration of the world's environment. Although nitrogen oxides and sulfur oxides do not cause the greenhouse effect, these gases can turn into acids when they meet water. Acid ...

Problems solved by technology

The disadvantages of these three methods are: 1. all will increase the energy consumption of the microbial culture process, thereby increasing the production cost; 2. the mode of the microbial incubator cannot be enlarged to the scale of industrial production; ④ For microalgae cultivation, the existing technology can only provide carbon dioxide gas and light energy to a small number of microalgae cells for photosynthesis at the same time, which reduces the cultivation efficiency
