Problems solved by technology

Although there are many types of closed photobioreactors, the only one reported for large-scale production is a pipe-type photobioreactor with an annual output of hundreds of tons of algae powder, and the cost of this equipment and maintenance costs are very high. Difficult to popularize
[0004] On the other hand, the production cost of microalgae cultivation is also high, firstly the cost of raw materials, and secondly the cost of harvesting

Embodiment 1

[0018] Embodiment 1 (single reactor)

[0019]The single air-push photobioreactor for cultivating microalgae is an annular shallow pool 1 built with bricks and concrete, and a partition wall 2 with open ends is built with bricks in the pool. The width of the pool is 3 meters, and the length is 60 meters. meters and a depth of 40 cm. The bottom of the air-push photobioreactor is equipped with a liquid discharge pipe 3, and the upper part is equipped with a liquid replenishment pipe 4. Intake pipe 5 is fixed on the partition wall in the middle part of the air-push photobioreactor, and 120 L-shaped branch pipes 6 are connected on the air inlet pipe. The wall is vertical; a row of small holes with a diameter of 1 mm is evenly opened on the side wall of the horizontal tube, the density of the holes is 3 per cm, and the airflow direction is horizontally forward, thus, the air-push photobiological reaction The water body in the container is driven by countless tiny airflows in the s...

Embodiment 2

[0023] Embodiment 2 (multiple reactors)

[0024] In industrialized large-scale production of microalgae, it is necessary to use multiple air-push photobioreactors for parallel production. The layout of the reactors and pipelines is shown in Figure 2. In each row, the reactors are closely arranged, leaving only the distance between two adjacent reactors for the pipeline. An operation channel of 0.5 meters should be reserved between two adjacent rows of reactors to facilitate operations such as film laying, sampling, opening skylights for ventilation, cleaning, and switching valves.

[0025] The east-west layout of the gas supply main pipe and the liquid replenishment main pipe passes through each row of reactors and divides into a north-south branch pipe, which enters the reactor at the end of each reactor to supply gas and liquid for the reactor. When collecting the algae liquid, the algae liquid is first discharged into a north-south branch pipe next to the reactor, and then...

Abstract

The invention relates to a micro-algae industrialization production device and a method of producing the micro-algae, which belong to the engineering field of the micro-algae culturing and the technical field of the environmental protection. An air-pushed type photobiology reactor unit device is an annular shallow pond built by bricks and concrete, an isolation wall with both ends opened is built in the shallow pond, a liquid drainage pipe and a liquid replacement pipe are arranged in the air-pushed type photobiology reactor unit device, an air inlet pipe is fixed on the isolation wall in the middle part of the air-pushed type photobiology reactor unit device and is connected with a plurality of L-shaped branch pipes, a plurality of micro blowholes are arranged on side walls of the transversal pipes of the branch pipes, the whole air-pushed type photobiology reactor unit device is covered by agricultural film and is provided with a skylight, to form an enclosed type photobiology reactor. The device combines the individual advantage of the open type photobiology reactor and the enclosed type photobiology reactor, by adopting the industrial waste gas and the eutrophication surface water or the industrial wastewater as the main raw material to perform micro-algae culturing in a large scale, especially to culture the micro-algae with high oil percentage, to provide the large or medium sized bio-diesel factory with raw oil, and simultaneously the emission reduction of carbon dioxide and the treatment of polluted water body are realized.

Description

[technical field] [0001] The invention relates to the field of microalgae cultivation engineering and the field of environmental protection technology, in particular to a microalgae industrial production device and a method for producing microalgae. [Background technique] [0002] Microalgae can effectively utilize light energy, carbon dioxide, and inorganic salts to synthesize fats, proteins, polysaccharides, and a variety of high-value-added biologically active substances. With the continuous deepening of human understanding of microalgae, the development and development of new high-efficiency photobioreactors and their cultivation methods have become an important part of microalgae bioengineering technology. [0003] At present, there are mainly two types of photobioreactors for microalgae cultivation: open and closed. There are four main types of open photobioreactors: shallow pools, circulating pools, runway pools, and ponds. Among them, the most typical and commonly ...
