Device for culturing microalgae

Abstract

The invention relates to a device for culturing microalgae. The device comprises an algae liquid storage unit, an algae liquid conveying device and an algae liquid guide surface, wherein algae liquid stored in the algae liquid storage unit forms an algae liquid area; the algae liquid guide surface is high than the liquid level of the algae liquid area in the algae liquid storage unit; the algae liquid conveying device conveys the algae liquid of the algae liquid area in the algae liquid storage unit to the algae liquid guide surface; the algae liquid forms a flowing algae liquid layer on the algae liquid guide surface and receives the irradiation of the sun; and the algae liquid flows out of the algae liquid guide surface and falls into the algae liquid area in the algae liquid storage unit. The device provided by the invention can be used for culturing the microalgae with large scale, low cost and high efficiency.

Description

technical field [0001] The invention relates to a device for cultivating microalgae. Background technique [0002] Microalgae are a class of low-level plants that grow in water with a wide variety and are extremely widely distributed. It is a cell factory driven by sunlight, and absorbs CO through efficient photosynthesis of microalgae cells. 2 , convert light energy into chemical energy of carbohydrates such as fat or starch, and release O 2 . The use of microalgae to produce bioenergy and chemicals can simultaneously achieve "replacing fossil energy and reducing CO 2 The three purposes of "emission, purification of waste gas and sewage". The advantages of "microalgae biotechnology" lie in the following aspects: ① Microalgae is the original plant with the highest photosynthetic efficiency. Compared with crops, the yield per unit area is dozens of times higher Microalgae is also the fastest-growing plant in nature, usually within 24 hours, the biomass contained in microal...

AI Technical Summary

Problems solved by technology

Although the reactor is very efficient, the structure of the multi-layer pallet is very complicated, which is not conducive to large-scale scale-up production

[0014] From the analysis of existing technologies, it can be seen that the main obstacles hindering the application of closed microalgae photobioreactors to large-scale industrial production are the complex structure, high investment cost and high operation cost of various closed photobioreactors.

Although technically feasible, economically unreasonable

Although the structure of the open pool system is simple, the investment cost and operating cost are low, but the efficiency is low, and the operating parameters are difficult to control, which can easily lead to serious cultivation problems
