A bionic laminated microalgae photosynthetic reactor

Abstract

The invention discloses a bionic laminated microalgae photosynthetic reactor. A submersible pump is arranged at the bottom of a microalgae culture liquid storage tank and is connected with water feeding distribution pipes which are uniformly distributed on the top of a tower main body angle steel bracket through a main suction tube; a photosynthetic reactor liquid storage tank is fixed on the tower main body angle steel bracket through a liquid storage tank angle steel bracket; the liquid storage tank angle steel bracket in the photosynthetic reactor liquid storage tank and the tower main body angle steel bracket form a triangular cuboid; a stainless steel wire mesh is fixed in the triangular cuboid formed by the liquid storage tank angle steel bracket and the tower main body angle steel bracket; a transparent plastic film is fixed on the inner side of the stainless steel wire mesh; a transparent corrugated plastic drainage plate is fixed on the outer side of the stainless steel wire mesh; the upper edge of the transparent corrugated plastic drainage plate is slightly higher than the upper edge of the stainless steel wire mesh; and the whole reactor consists of multiple photosynthetic reactor liquid storage tanks from a smaller size to a larger size from top to bottom. The bionic laminated microalgae photosynthetic reactor has the characteristics of high photosynthetic efficiency, energy conservation, high efficiency and convenience in maintenance and can realize economic large-scale continuous microalgae cultivation.

Description

technical field [0001] The invention relates to a bionic laminated photosynthetic bioreactor for cultivating microalgae. Background technique [0002] At present, under the background of depletion of fossil fuels and massive emission of greenhouse gases, it is becoming increasingly important to develop renewable energy, carry out energy conservation and emission reduction, and develop circular economy. Microalgae as a new type of biofuel can effectively utilize CO 2 People pay more and more attention to photosynthesis. At the same time, microalgae have a wide range of application values ​​in food, feed, medicine, and sewage purification. [0003] With the deepening of microalgae research, people gradually realized that photobioreactor is an important factor limiting the high-density and efficient cultivation of microalgae, and the development and development of new high-efficiency photobioreactors has become the key to the industrialization of microalgae biotechnology One ...

Problems solved by technology

The advantages of the open reactor are simple construction, low cost and simple operation, but the disadvantages are also obvious: (1) The reactor occupies a large area and the land utilization rate is low; The efficiency is not high; (3) Mechanical agitation is used to promote the exchange of substances and energy in the culture, which consumes a lot of energy. (4) Open microalgae photobioreactors are generally built on the ground, and the pollution of surface water, animals, and litter is relatively serious

[0005] Although the closed photobioreactor overcomes the shortcomings of the open microalgae photosynthetic reactor to some extent, there are still serious shortcomings: (1) The cost of the reactor is relatively high, the operation requirements are also high, and the operation and maintenance costs such as cleaning are relatively high. (2) Oxygen accumulation is prone to occur in the closed reactor, which will have a toxic effect on the growth of microalgae, which is a common problem in the closed reactor; (3 ) When the concentration of algae in the reactor is relatively high, the light transmittance of the closed reactor becomes poor, which affects the light efficiency
