High-efficiency microalgae light reaction device

Abstract

The invention discloses a high-efficiency microalgae light reaction device including a culture tank, a light reactor, a jet device, an aeration device and a fan; a culture tank cover is arranged above the culture tank, the culture tank cover is provided with a gas detection hole; the light reactor, the jet device and the aeration device are arranged in the culture tank, the light reactor is fixedly connected in the culture tank through a bracket, the jet device is symmetrically arranged in the culture tank, the aeration device is arranged at the bottom of the tank culture; a liquid heat conducting medium is arranged in the light reactor; the jet device and the aeration device are driven by a gas supplied by the fan. The device completely abandons the method of water pump plugging, adopts a mode of the fan to realize the stirring effect by using a gas, reduces energy consumption, reduces the motor damage caused by steam, and increases the service life. The liquid heat conducting medium is arranged in the light reactor to effectively improve the heat radiating effect, avoids light failure phenomenon, increases the photosynthesis time, and improves the efficiency of carbon fixation.

Description

technical field [0001] The invention relates to the field of microalgae biotechnology, in particular to a high-efficiency microalgae photoreaction device. Background technique [0002] Microalgae are organisms with the highest photosynthetic efficiency, rich in protein, polyunsaturated fatty acids and carotenoids and other high value-added substances. At the same time, microalgae have the ability to absorb nitrogen, phosphorus and accumulate oil during cultivation . Therefore, microalgae has a wide range of applications in many aspects such as food, bait, feed, environmental protection, and bioenergy. . In addition, the potential of microalgae to fix carbon and microalgae to treat wastewater rich in nitrogen and phosphorus is also very great. [0003] Photobioreactors generally refer to equipment or devices used to cultivate photosynthetic micro organisms and plant tissues or cells with photosynthesis. At present, there are mainly two types of photobioreactors used for m...

AI Technical Summary

Problems solved by technology

Existing photobioreactors use motors to achieve gas circulation through water pumps. Water gas and motor products cannot be effectively isolated, and motor failures are likely to occur, reducing service life.

Moreover, the heat dissipation effect of the existing photobioreactor is not good, which will lead to the occurrence of light decay and cause damage to the reactor, thereby affecting the progress of photosynthesis
