Description
Technical field
The utility model relates to a kind of bioreactor, is specifically related to a kind of closed photo bioreactor.
Background technology
When utilizing existing bioreactor to carry out microdisk electrode, usually need the mixed gas passing into air and carbonic acid gas in phototropic reaction device, force algae liquid to flow, realize the well suspended of microalgae cell in photoreactor.Existing bioreactor mainly utilizes air to force algae liquid to flow, and containing a lot of uncertain composition in air, comprises other micro-algae or microorganisms, be easy to culture is infected, cause the underproduction or cultivate unsuccessfully.In addition, be passed into carbonic acid gas in reactor by Dilution air with air, and be directly lost to air with air from reactor body short transverse, well do not absorbed by micro-algae.Most of carbonic acid gas is basic does not just touch micro-algae, does not even have enough time to be dissolved in nutrient solution, is just walked to be lost in air by airstrip and gone, not only have impact on photosynthesis effect, and causes carbonic acid gas waste.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of closed photo bioreactor, realizes the closed cultivation of flat plate photobioreactor, alga cells can fully circulate suspend prerequisite under avoid atmospheric pollution and carbonic acid gas waste.
The technical solution of the utility model is as follows:
A kind of closed photo bioreactor, comprise the rectangular-shaped cylinder body be made up of transparent material, the vertical partition that some pieces are played guide functions is furnished with along its length equally spacedly in cylinder body, space uniform in cylinder body is divided into several space cells comprising first unit and tail unit by vertical partition, it is characterized in that: wherein the upper end of tail unit is provided with dash filler, be provided with the gas skirt covering tail unit upper port above dash filler, other space cell upper end is closed by transparent panel; Also comprise blower fan, the air intake of blower fan is connected with gas skirt by the first pipeline, and the outlet air end of blower fan is connected with described first unit by the second pipeline; Second pipeline is also connected with gas-adding pipe.
Positively effect of the present utility model is:
Carbonic acid gas enters in cylinder body through the second pipeline, and under vertical partition water conservancy diversion on current downflow, baffling state carbonic acid gas stir under, the micro-algae in algae liquid is in good suspended state all the time.Unabsorbed carbonic acid gas enters gas skirt from tail unit through dash filler, then enters the first pipeline and forms circulation.Under vertical partition guide functions, achieve the well suspended of alga cells, obviously alleviate microalgae adherence and deposited phenomenon.Said process algae liquid not ingress of air, carbonic acid gas participates in circulation all the time, and algae liquid turbulent flow is abundant, thus achieve the closed cultivation of flat plate photobioreactor, alga cells can fully circulate suspend prerequisite under avoid atmospheric pollution and carbonic acid gas waste, and reduce system energy consumption, improve efficiency and the quality of alga cells cultivation.
Accompanying drawing explanation
Fig. 1 is structure and working principle schematic diagram of the present utility model.In figure, arrow is used to indicate carbon dioxide flows direction.
Embodiment
The utility model is further illustrated below in conjunction with embodiment and accompanying drawing.
As Fig. 1, embodiment of the present utility model comprises the rectangular-shaped cylinder body 1 be made up of transparent material, and cylinder body 1 length is much larger than its height and width.The vertical partition 2 that some pieces are played guide functions is furnished with along its length equally spacedly in cylinder body 1, vertical partition 2 will be divided into several space cells comprising first unit and tail unit space uniform in cylinder body 1, unit headed by between the vertical partition 2 that in Fig. 1, cylinder body 1 left end sidewall is adjacent is tail unit between the vertical partition 2 that cylinder body 1 right end sidewalls is adjacent.Wherein the upper end of tail unit is provided with dash filler 4, is provided with the gas skirt 3 covering tail unit upper port above dash filler 4, and other space cell upper end is closed by transparent panel.
Also comprise blower fan 6, the air intake of blower fan 6 is connected with gas skirt 3 by the first pipeline 5, and the outlet air end of blower fan 6 is connected with described first unit by the second pipeline 8.Second pipeline 8 is also connected with gas-adding pipe 7, and inlet pipe 7 connects carbon dioxide air source by control valve.
Opening controlling valve, carbonic acid gas enters in cylinder body 1 through inlet pipe 7 and the second pipeline 8, and under vertical partition 2 water conservancy diversion on current downflow, baffling state carbonic acid gas stir under, the micro-algae in algae liquid is in good suspended state all the time.Unabsorbed carbonic acid gas enters gas skirt 3 from tail unit through dash filler 4, then enters the first pipeline 5 and forms circulation.
Carbonic acid gas is constantly consumed (participation photosynthesis) by absorption in cylinder body inner cyclic process, is measured the potential of hydrogen of algae liquid, increase carbon dioxide amount when pH is less than set(ting)value by control valve by the pH meter be placed in cylinder body 1.
Closed photo bioreactor of the present utility model also comprises the algae liquid outer circulating tube that two ends are connected with described cylinder body 1 respectively, and is provided with switch-valve and liquid pump on this algae liquid outer circulating tube.This algae liquid outer circulating tube is also connected to algae liquid and nutritive salt adding set and micro-algae collection device.Under blower fan 6 stopped status, open the switch-valve on algae liquid outer circulating tube, rely on liquid pump power to implement the cylinder body outer circulation of algae liquid, implement algae liquid and nutritive salt adding set and micro-algae in outer loop process and collect.
