Description
Technical field
The invention belongs to life and Treatment of Industrial Water technical field, the structure design that relates to anode of microbial fuel cell is particularly related to a kind of spiral channel column anode.
Background technology
Microbiological fuel cell (Microbial fuel cell, be called for short MFC) be to be biological catalyst with the microorganism, directly the chemical energy of fuel is converted into a kind of special fuel cell of electric energy, it is applied in sewage treatment area, collection electrogenesis and sewage purification are one, have very bright and tempting application prospect.
Chinese patent application " microbiological fuel cell " 200410066753.9, " detecting the method and apparatus of toxic substance in the water with microbiological fuel cell " 03807769.8, " microbiological fuel cell of no film and no amboceptor " 03813043.2, " a kind of microbiological fuel cell " 200420090582.9, " a kind of medium-free microbial fuel cell " 200510079759.4, " a kind of bitubular type microbiological fuel cell " 200610113873.9, " bioreactor-direct microbe fuel cell and uses thereof " 200510086618.5, " Stackable single cell microbe fuel battery " 200610144991.6.
Following problem appears in above patent in the actual sewage treating processes:
[1] the reactor internal resistance is bigger, and electricity generation ability is low;
[2] adopt pellet electrode, biomass content is lower, and its structure is not suitable for Large scale construction;
[3] adopt the filler electrode, filler stops up easily, reduces the cycle of operation.
Summary of the invention
At the problems such as obstruction that existing packing type anode occurs, the present invention proposes a kind of spiral channel column anode, prevents that when increasing the anode attached microbial electrogenesis microorganism hypertrophy from causing anode to stop up.
This anode comprises water-in (1), base plate (2), dividing plate (3), perforation carbon felt (4), graphite rod (5), proton film (6), top board (7) and water outlet (8);
Proton film (6) surrounds tubular structure, and two ends bond together with top board (7) and base plate (2) respectively, constitute the anolyte compartment jointly;
Described base plate (2) is provided with described water-in (1), and described top board (7) is provided with water outlet (8);
Comprise in the anolyte compartment: column anode, be screwed into the graphite rod (5) in the column anode;
Described columnar samples is very: go up even cloth hole at perforation carbon felt (4), between the adjacent carbons felt behind the staggered certain angle with being sintered to an integral body behind the phenolic resin adhesion again, form inner column anode with helical flow path, be used to prevent that the packing type anodic from stopping up;
Screw thread is carved with on described graphite rod (5) surface, it is screwed in strengthen contacting between graphite and the carbon felt in column anode, is used to collect anodic current.
During the work of described column anode: sewage flows into the anolyte compartment from lower water inlet (1), behind dividing plate (3), because flow passage resistance force of waterproof is less, most of sewage rises along the runner spiral, and a small amount of sewage directly penetrates the carbon felt, rise by carbon felt internal void, does carbon felt surface length have microbial film (what microbial film? explain unclear), in the process of drainage flow, microbial film is with the organic matter degradation in the sewage, the electronics that produces is delivered to central graphite rod (5) by the carbon felt and derives, and the sewage after the processing flows out from top water outlet (8).
Described sintering processing is for to carry out under 600 ℃ of protection of nitrogen gas.
Described spiral type runner is the main channel that sewage passes, and is used to prevent that the hypertrophy of electrogenesis microorganism from causing anode to stop up, and has prolonged hydraulic detention time simultaneously.For the layout of helical flow path, can change the flow pattern of sewage by the number in hole and the angle of rotation between the carbon felt on the change carbon felt in electrode interior.
Described dividing plate (3) is a porous plate, is used for support carbon felt and water distribution uniformity.
Beneficial effect of the present invention: the present invention compared with prior art has the following advantages and the high-lighting progress: adopt the material filling type electrode, increased the bond area of microorganism, effectively reduce the internal resistance of cell, improve electricity generation ability; By at filler internal layout helical flow path, prolonged hydraulic detention time, prevent the latch up phenomenon that the microorganism excessive increase is caused simultaneously; Improve graphite rod and the mode of connection of carbon felt and the sintering processing between the carbon felt, make electrode have better electroconductibility.
