Description
Technical field
The present invention relates to a kind of biomimetic type laminated type photosynthesis physiological target for cultivating micro-algae.
Background technology
Under the background that, greenhouse gases day by day exhausted at fossil oil discharge in a large number at present, exploitation renewable energy source, carries out energy-saving and emission-reduction, develops a circular economy and become increasingly important.Micro-algae, as a kind of novel biofuel, effectively can utilize CO
2carry out photosynthesis, be more and more subject to people's attention, simultaneously micro-algae is with a wide range of applications in food, feed, medicine, the many aspects such as to purify waste water.
That studies along with micro-algae deepens continuously, and people recognize gradually, and bioreactor is the important factor limiting micro-algae high-density high-efficient culture, and the new and effective bioreactor of development has become one of gordian technique of Microalgae biotechnology industrialization.
At present, the bioreactor of microdisk electrode mainly divides open and closed two kinds.The advantage of open reactive device be build simple, with low cost and simple to operate, shortcoming also clearly: (1) reactor floor space is large, and land utilization ratio is low; (2) illuminating surface is long-pending low with the ratio of volume, and micro-algae photosynthetic efficiency is not high; (3) adopt the exchanges of mass and energy that mechanical stirring promotes in culture, large (4) the open microalgae photobiological reactor of energy consumption is generally built on the ground, and surface water, animal, dry branches and fallen leaves damage ratio are more serious.
Although closed photo bioreactor overcomes the shortcoming of the open algae photosynthetic reactor that declines to a certain extent, but also there is serious deficiency: the cost compare of (1) reactor is high, operational requirement is also high, the operation and maintenance costs such as cleaning are very high, become the bottleneck problem of Closed photobioreactor commercial application; (2) oxygen easily occurs in closed reactor to pile up, can produce toxic action to the growth of micro-algae, this is the common fault of closed reactor; (3) when the concentration of algae in reactor is higher, the light transmission of closed reactor is deteriorated, and have impact on light efficiency.
Summary of the invention
The object of the invention is to propose a kind of biomimetic type lamination to decline algae photosynthetic reactor, can increase substantially micro-algae output, efficiently carbon admittedly, low cost, convenient operation, safety coefficient are high.
The present invention is achieved by the following technical solutions.
The present invention is made up of microalgae culture liquid storage tank (1), submersible pump (2), main body tail pipe (3), turriform main body angle bar frame (4), photosynthetic reactor reservoir (5), upper water distribution (9).
Submersible pump (2) is placed at the bottom of microalgae culture liquid storage tank (1) pond, and be connected with the equally distributed upper water distribution (9) in turriform main body angle bar frame (4) top by main body tail pipe (3), photosynthetic reactor reservoir (5) is fixed on turriform main body angle bar frame (4) by reservoir angle bar frame (10).
Described photosynthetic reactor reservoir (5) is made up of lightweight transparent plastics film (6), Stainless Steel Cloth (7), transparent corrugation plastic drainage plate (8), reservoir angle bar frame (10); Reservoir angle bar frame (10) and turriform main body angle bar frame (4) form triangle rectangular parallelepiped, Stainless Steel Cloth (7) is fixed on reservoir angle bar frame (10) and forms in triangle rectangular parallelepiped with turriform main body angle bar frame (4), transparent plastic film (6) is fixed on Stainless Steel Cloth (7) inner side, transparent corrugation plastic drainage plate (8) is fixed on the outside of Stainless Steel Cloth (7), and transparent corrugation plastic drainage plate (8) upper limb is a little more than the upper limb of Stainless Steel Cloth (7).Whole reactor is made up of some ascending photosynthetic reactor reservoirs (5) from top to bottom.
Principle of work of the present invention is: with submersible pump (2), the microalgae culture in microalgae culture liquid storage tank (1) is pumped into is positioned at the equally distributed upper water distribution (9) in turriform main body angle bar frame (4) top by main body tail pipe (3), evenly spread in the photosynthetic reactor reservoir (5) of top, segregation drive is relied on to flow in lower one deck photosynthetic reactor reservoir along transparent corrugation plastic drainage plate (8) after nutrient solution overflows, microalgae culture is descending step by step in this way, until flow to lowermost end microalgae culture liquid storage tank (1), form algae liquid exploitation formula circulation loop.
The present invention can also by increasing the input aperture of a fresh micro-algae culture medium at main body tail pipe (3), and increase a culture outlet at microalgae culture liquid storage tank (1), fresh culture thing inlet and microalgae culture discharge are balanced, namely realizes continuous seepage.
The quantity of photosynthetic reactor reservoir (5) of the present invention can increase and decrease according to need of production.
The inclination angle of the Stainless Steel Cloth (7) of photosynthetic reactor reservoir (5) of the present invention can be adjusted according to the change of the solar incident angle of each lamination distance floor level and Various Seasonal, makes sunlight light as far as possible evenly incide each position of reactor.
Length in the horizontal direction of turriform main body angle bar frame, can adjust according to need of production.
The present invention has following technique effect: the biological structure feature of the overall imitation arbor of reactor, and shape is laminated type pyramidal structure, does not block mutually between layers, can accept solar irradiation the most fully, carry out photosynthesis, reaches efficient carbon object admittedly.Whole framework is multiple trilateral and connects, and layer angle of inclination is adjustable arbitrarily, when making full use of luminous energy, keeps the stability of whole system; The whole frame material of reactor is stainless steel, and it is meshy steel wire structure that interlayer lifts material, and light transmission is good, and reactor body selects lightweight transparent plastics, utilizes meshy steel wire structure to fix, and solves glass reaction and thinks highly of and the shortcomings such as danger coefficient height; The flow pattern of reactor then have employed overflow manner, have transparent drainage baffle plate layer by layer, algae liquid flows to lower level floor along drainage baffle plate under the force of gravity, increases and stirs, be conducive to the contact of algae and outside air, effectively reduce the phenomenon of the adherent growth of algae.Therefore having photosynthetic efficiency high, efficient energy-saving, feature easy to maintenance, is the good equipment realizing the cultivation of economic micro-algae large-scale continous way.
