Description
Technical field
The present invention relates to a kind of comprehensive experiment shelf of microbiological fuel cell; But this experiment frame sacrificial vessel has the laboratory of different spaces size and space type to select to use, and is fit to carry out extensive microbiological fuel cell experiment or limited laboratory, space and studies use on a small scale.This invention is applicable to the energy environment area research, for the research of microbiological fuel cell provides standardization, modular experimental situation, embodies the theory of energy-conserving and environment-protective simultaneously, and the microbiological fuel cell research department that can supply day by day to increase uses.
Background technology
The develop rapidly of world economy, population support's sharp increase have consumed a large amount of fossil energies, have caused the serious environmental pollution.Countries in the world are all striving to find and are greatly developing clean energy resource.(Microbial Fuel Cells is that a kind of enzyme that utilizes anaerobe will be stored in the technology that chemical energy in the organism is converted into electric energy MFCs) for microbiological fuel cell technology.The battery that with organic wastewater is fuel can be purified waste water in electrogenesis; It is a tool clean energy technology with broad prospects for development; Caused home and abroad environment field, chemical field, biological field, the large quantities of experts and scholars' of field of materials attention, domestic existing how tame colleges and universities begin this Study on Technology.The Scientific Research in University Laboratory space is very limited usually, and rationally utilizing every cun space is the aspect that each laboratory development all will be concerned about.
The research microbiological fuel cell unavoidably will be gathered the electric signal that produces; The electricity that current battery produces is a light current; Receive extraneous interference easily; The electromagnetic signal of for example testing generation when starting such as required motor, pneumatic pump, peristaltic pump can influence data acquisition unit work, causes data acquisition to be interrupted.In addition, when research larger, number of batteries more for a long time, too much lead causes testing the table top confusion easily, signal record is made mistakes.And the voltage output end of battery (lead) directly links to each other with capture card (binding post), is inconvenient to change cell solution and acquisition channel.
Various organic wastewaters are adopted in the laboratory at present; Or even the industrial waste water of difficult degradation is done battery fuel; Do anode inoculation bacterium source with the anaerobic sludge of sewage treatment plant; The stink that waste water is revealed and anaerobic sludge distributes causes secondary pollution easily, mainly is to pollute breadboard air and corrosion experiment desktop.
The microbiological fuel cell of making inoculation source of pure bacterium is often relatively harsher to environment requirement, and when for example studying with Thermophilic Bacteria, unsuitable its existence of room temperature just need be controlled the operating ambient temperature of battery.When research temperature during to the influencing of battery electrogenesis, the operating ambient temperature that also requires battery is regulatable.This just needs the special Experimental Area of layout can realize temperature adjusting.
Be the biological anaerobic environment of holding anode, the anode chamber is airtight.Anolyte is even during for the realization intermittent duty; The mode of generally using now is sub with magnetic agitation, and when moving continuously, adopts the peristaltic pump feed liquor usually; This has not only increased energy consumption and experimental cost; And cause experiment table confusing easily, and therefore need carry out unified planning and layout to mixing plant, consider that simultaneously the advantage of giving full play to shelf reduces the experiment energy consumption.
Based on above some; A kind of specialization, synthesization, normalized microbiological fuel cell comprehensive experiment shelf are demanded exploitation urgently; Enable to solve the problem that the signals collecting that occurs in the present microbiological fuel cell research is interfered, waste water and gas secondary pollution problem, the problem that experiment table is confusing; Reduce the experiment energy consumption and practice thrift cost etc., satisfy other required specific (special) requirements of experiment simultaneously.
Summary of the invention
The objective of the invention is to design a kind of microbiological fuel cell comprehensive experiment shelf; Can satisfy three big requirements of present laboratory study needs; That is: electric signal is gathered in real time, regional temperature is regulated and control and evenly mix cathode and anode solution; Embody the principle of economizing simultaneously, improve the lab space utilization factor and reduce experiment energy consumption and cost to a certain extent.
The present invention realizes through following scheme:
Experiment frame divides console mode and two kinds of forms of unsettled wall-attaching type; The console mode experiment frame presents vertical structure, and longitudinal size is greater than lateral dimension, layered arrangement; Be suitable for the complete and sufficient laboratory of solid space; Can reach the purpose that data acquisition makes things convenient for and make full use of the space simultaneously, and every layer of easily dismounting, make things convenient for scale to enlarge.Unsettled wall-attaching type frame can be arranged in experimental implementation platform top, can make full use of the thin-and-long space, is fit to very much limited laboratory, space and uses.
Frame body main body is used cold-rolled steel sheet, can bear the desired weight of experiment and certain leeway is arranged.Surface plastic spraying can effectively prevent the waste water corrosion frame body of revealing.
This experiment frame is avoided capture card and is connected with the permanent of battery output terminal; Realize breaking off immediately and being connected through red-black conductive jack in the middle of both; Red (deceiving), the look jack forever was connected with data collecting card; The output terminal of battery is connected to red (deceiving) plug, when plug inserts conductive hole, connects Acquisition Circuit, breaks off Acquisition Circuit when extracting.So, realize being convenient for changing the acquisition channel of battery and not disturbing mutually, simple to operate.Conductive jack is arranged in frame body both sides, and the shelf both sides are the woodwork plate material, can effectively prevent the interference of electric signal between the passage.
The binding post and the conductive jack of capture card are wired to the position, and corresponding one by one, and plug hole and lead indicate sequence number, make mistakes when avoiding reading of data.
Lead is stored in the magazine and indicates label, has avoided the confusing and lead corrosion of lead and has exposed the potential safety hazard of initiation.
Shield extraneous forceful electric power signal with openable stainless steel cage, prevent the interference to capture card, guarantee that data acquisition is safe and reliable, the while is the dismounting data collecting card easily.
This experiment frame is arranged special airtight test block; Adopt the temperature in the air bath method control area; Give atmosphere temperature rising in the zone through firing equipment, realize that through fan and thermopair regional temperature is even and stable, can realize regional temperature is controlled at 37 degree or 25 degree; Fluctuate less than 2 degree, the temperature difference is lower than 1 degree in the zone.
This experiment frame is integrated with magnetic stirring apparatus and testing table, by the break-make electricity that is arranged in the master switch control stirrer on the testing table front console, by stepless adjustable knob realize to single stirring-head unlatching, close and rotational speed regulation.Numeral shows the rotating speed of single stirring-head.So, the confusion phenomena when having avoided a plurality of stirrers to use together, testing table are neatly unified.
The experiment frame top layer is arranged the hook of hiding, and can cell solution be hung upside down before experiment frame, to make solution from flowing into the battery that is placed on lower shelves.So, both reduce the use of peristaltic pump, given full play to the advantage of shelf again.
