Circulating closed microalgae cultivation production system

Abstract

The present invention relates to a microalgae breeding production control machine, a circulating closed multifunctional microalgae breeding reactor, a closed light-transmitting culture pool, the above-mentioned microalgae breeding production control machine, a circulating closed multifunctional microalgae breeding reactor and an airtight A microalgae cultivation production system composed of light-transmitting culture ponds. In the present invention, the microalgae cultivation production control function can integrate the hydraulic pump, air fan, control valve, electrical control equipment and programmable control system required in the microalgae cultivation production system into an independent equipment unit to replace The traditional way of independent operation of each unit achieves centralized monitoring and management and greatly simplifies the process unit.

Description

technical field [0001] The invention relates to a technology and process equipment for cultivating and producing microalgae in large quantities. Background technique [0002] The microalgae cultivation system can be divided into two types: open type and closed type. The open type system uses sunlight for cultivation outdoors, while the closed type system must be cultivated in a photobiochemical reactor. Therefore, different forms of photobiochemical reactors are opened. The developed microalgae culture system is also different. [0003] Known comparatively feasible microalgae production methods have two kinds: (1) culturing bag culture system, (2) tubular photobiochemical reactor culture system. [0004] The known microalgae cultivation process can be divided into the following three process systems, (1) culture solution supply system, (2) gas mixing circulation system, and (3) culture product harvesting system. [0005] Such as figure 1 As shown, known culture bag cultiv...

Problems solved by technology

[0009] 4. Breeding product harvesting system: the cultivated microalgae products will settle under the culture bag 10a. Since the culture bag 10a is a light-transmitting plastic bag, it cannot be opened at the bottom, and the microalgae culture solution recovery pump 17a is required to collect the water from each bag. The branch culture bag 10a is pumped to the microalgae liquid collection tank 18a, which cannot be operated automatically and is time-consuming and laborious

[0016] But the closed breeding system known in the past still has its shortcomings, such as too many equipment units in the closed breeding production system, the cultivation volume is small, the finished product harvest is not automated, and a large amount of manpower is needed, which increases the cost and reduces the production efficiency. As a result, the scale of production is limited and it is not easy to scale up. This is also a barrier that needs to be broken through in closed microalgae cultivation.
