Description

A kind of biomimetic type lamination algae photosynthetic reactor that declines
Technical field
The present invention relates to a kind of for cultivating the biomimetic type laminated type photosynthetic organism reactor of micro-algae.
Background technology
Under the backgrounds of fossil oil exhaustion day by day, a large amount of discharges of greenhouse gases, exploitation renewable energy source, carries out energy-saving and emission-reduction, develops a circular economy and becomes increasingly important at present.Micro-algae, as a kind of novel biofuel, can effectively 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 purify waste water.
Along with deepening continuously of micro-algae research, people recognize gradually, and bioreactor is an important factor of the micro-algae high-density high-efficient culture of restriction, and the new and effective bioreactor of development has become one of gordian technique of Microalgae biotechnology industrialization.
At present, the bioreactor that micro-algae is cultivated mainly divides two kinds of open and closeds.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) illumination surface to volume ratio is low, and micro-algae photosynthetic efficiency is not high; (3) adopt mechanical stirring to promote the exchanges of mass and energy 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 has overcome 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 and pile up, can produce toxic action to the growth of micro-algae, this is the common fault of closed reactor; (3), in the time that the concentration of algae in reactor is higher, the light transmission variation of closed reactor, has affected light efficiency.
Summary of the invention
The object of the invention is to propose a kind of biomimetic type lamination algae photosynthetic reactor that declines, 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 micro-algae 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).
At the bottom of submersible pump (2) is placed in micro-algae culture liquid storage tank (1) pond, and be connected with turriform main body angle bar frame (4) the equally distributed upper water distribution in top (9) 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 plastic 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) composition 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: the micro-algae culture in micro-algae culture liquid storage tank (1) is pumped into and is positioned at turriform main body angle bar frame (4) the equally distributed upper water distribution in top (9) by main body tail pipe (3) with submersible pump (2), evenly spread in the photosynthetic reactor reservoir (5) of top, nutrient solution overflows rear dependence segregation drive and flows in lower one deck photosynthetic reactor reservoir along transparent corrugation plastic drainage plate (8), micro-algae culture is descending step by step in this way, until flow to the micro-algae culture of lowermost end liquid storage tank (1), form algae liquid exploitation formula circulation loop.
The present invention can also be by increasing the input aperture of a fresh micro-algae culture medium at main body tail pipe (3), and increase a culture outlet at micro-algae culture liquid storage tank (1), make fresh culture thing inlet and micro-algae culture discharge balance, realize continuously and producing.
The quantity of photosynthetic reactor reservoir of the present invention (5) can increase and decrease according to need of production.
The inclination angle of the Stainless Steel Cloth (7) of photosynthetic reactor reservoir of the present invention (5) can be adjusted apart from the variation of the solar incident angle of floor level and Various Seasonal according to each lamination, 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 be according to need of production adjustment.
The present invention has following technique effect: the biological structure feature of the overall imitation arbor of reactor, be shaped as laminated type pyramidal structure, and do not block mutually between layers, can accept the most fully solar irradiation, carry out photosynthesis, reach efficient carbon object admittedly.Whole framework is multiple trilaterals and connects, and layer angle of inclination is adjustable arbitrarily, in the situation that 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 is lifted material, and light transmission is good, and reactor body is selected lightweight transparent plastics, utilizes meshy steel wire structure to fix, and has solved that glass reaction is thought highly of and the shortcoming such as danger coefficient height; The flow pattern of reactor has adopted overflow mode, layer by layer, have transparent drainage baffle plate, algae liquid flows to lower floor bottom along drainage baffle plate under segregation drive, increases and stirs, be conducive to contacting of algae and outside air, effectively reduce the phenomenon of the adherent growth of algae.Therefore there is photosynthetic efficiency high, efficient energy-saving, feature easy to maintenance, is the good equipment of realizing economic micro-algae large-scale continous way cultivation.
