Description

Algae farming device

The invention provides an algae culture device, in particular to an algae culture device for algae cultivation of photosynthesis 24 hours a day.

Due to the rapid increase of the Earth's population and the high development of industry and commerce, human beings will face great pressures such as lack of natural resources such as food, energy, minerals, building materials and the deterioration of the ecological environment. At present, countries all over the world are actively looking for alternative foods and alternative energy sources to slow down the consumption of natural resources, solve famine and energy problems, and prepare for future resource depletion. In general, algae, for example, various algae that absorb photosynthesis can absorb carbon dioxide and produce various useful ingredients rich in essential vitamins, amino acids, pigments, proteins, polysaccharides, cellulose, fatty acids, minerals, and the like. The active ingredients of algae have been proven to have antibacterial and antiviral activity, and can produce algin, alginate, diatomaceous earth, etc. Therefore, algae can be used as (1) edible: substitute food, health food, feed; (2) Industrial use: refining raw fuel, alternative energy; (3) medical use: refining anti-cancer substances, important raw materials for the pharmaceutical industry; (4) environmental protection: absorbing carbon dioxide from exhaust gas emitted by factories. Algae cultivation technology has been paid more and more attention in recent years due to the development value of algae for various uses.

For decades, many algae farming devices and methods have been proposed, and algae farming can be divided into open farming and closed farming.

The open culture is a traditional open-air cultured algae pond. It uses open ponds such as ponds as breeding grounds, and relies on sunlight as a source of light for algae photosynthesis. Although it has the advantages of low cost and large-scale farming, it is also too large. Need to stir, the breeding environment is vulnerable to pollution (such as dust, cockles, etc.), susceptible to weather, carbon dioxide easy to escape and other shortcomings, and only in the daytime algae can be exposed to sunlight, and the intensity of light irradiation It changes with the weather, and it is impossible to accurately control environmental factors such as temperature and amount of light, and photosynthesis can be carried out without rain on rainy days or at night, thus affecting the growth rate and growth stability of algae and reducing productivity. In the algae culture technology, most of the algae cultivation must be discharged after the mature cultivation of the algae culture, and then the culture pond is cleaned with a large amount of water for environmental protection work after the epidemic prevention. It takes time to re-water the water and then proceed to the next step. The cultivation of algae increases the cost of algae cultivation, and further, the algae after harvesting But also through many procedures to clean and wash consumption or use.

Due to the many shortcomings of the open-air cultured algae pond, the industry has developed a flat strip of polyethylene cultured on the ground and a long strip of polyethylene bag culture, relying on sunlight as a source of light for algae photosynthesis, although The sun-bathing area is large, and pollution can be avoided, the labor time for cleaning the algae pool can be saved, and the cost is low, but the disadvantage is that the algae water in the tube or the bag cannot be uniformly exposed to sunlight, and the photosynthesis light required for algae growth On the contrary, the growth of algae is often discounted, and the carbon-to-oxygen process in the long tubular or long-sleeve bags is not easy to convert smoothly in a moment, especially the high light heat value at noon, and the quality of the algae is not very homogeneous. In the rainy days or evenings, there is no sunshine to carry out photosynthesis. Therefore, the growth rate and growth stability of algae are affected, so that the productivity cannot be increased. In order to circulate the algae water, it is necessary to use a liquid pump to waste electrical energy, and thus it is necessary to be improved.

The closed culture is cultured through various closed culture devices. The current closed culture equipment includes fermentation tank, tubular photosynthetic reactor, plate photosynthetic reactor, spiral tubular photosynthetic reactor, etc., and closed culture has environmental factors. It is easy to control, not easy to be polluted, and has high breeding density. Compared with open farming, it can obtain higher productivity and better breeding effect. Therefore, many operators or research institutions currently use closed culture, but the disadvantages of closed culture equipment In order to operate and maintain the high cost, the light source cannot fully illuminate the culture device, so the brightness distribution in the reaction system is uneven, which also causes the algae culture growth efficiency to be poor, and needs to be improved.
