Description
Technical field
The invention belongs to direct liquid catalyst fuel cell field, be specifically related to a kind of sludge fuel battery, directly mud be converted into electric energy at low temperatures, fuel is made without any pretreatment.
Background technology
Mud (sludge) is the produced dope between liquid and solid of sewage disposal process, the extremely complex heterogeneous body being made up of organic detritus, microorganism, inorganic impurity and colloid etc..Along with quickening and the intensification of water degree for the treatment of of urbanization process, the yield of city sewage and sludge also sharply increases, it is contemplated that to the year two thousand twenty, sludge yield will break through 60,000,000 tons.Additionally, environment and human health are had heavy metal element and more pathogenic microorganism, parasitic ovum and the toxic organic compound of serious harm by mud possibly together with Cd, Pb, As, Cu and Zn etc..The problem of environmental pollution that mud causes becomes increasingly conspicuous, and has resulted in great potential safety hazard, ambient pressure and financial burden.The most reasonably dispose city sewage and sludge so that it is reach the purpose of " minimizing, innoxious and resource ", it has also become the key issue of China's City Ecological Environment Sustainable development.
On the other hand, from energy angle, the content of organics day by day improved in city sewage and sludge and calorific value also make its great energy recovery be worth, utilize advanced treatment technology, improve the energy recovery rate of city city sewage and sludge, and for Substitute For Partial Fossil fuel, for solving global warming, promoting Energy restructuring, realizing the sustainable development in pluralism of the energy, tool is of great significance.
Sludge power generation not only can realize the safe handling of mud, can also realize recycling sludge simultaneously and utilize, be the development trend of mud Appropriate application.Fuel cell has the advantage of energy conversion efficiency and environmental protection it is considered to be one has promising technology very much.Microbiological fuel cell technology (MFC) with mud as substrate, it is possible to achieve sludge degradation and generating synchronize, and power output density is 40～250mW/m2.But, this technology there is also has many deficiencies, as low in output power density, poor stability, sludge degradation efficiency are low, electrode material catalyst is expensive.Directly liquid catalyst fuel cell technology is a kind of brand-new fuel cell technology, and such as the biomass such as starch, cellulose, lignin can be at room temperature converted directly into electric energy by this technology.Containing a certain amount of organic matter in mud, organic matter fractions in mud can also be with the anodolyte generation redox reaction in liquid direct fuel cell in theory, producing electronics and proton, electronics is converted into electric energy through external circuit, the external organic mass-energy done work thus realize in mud.Liquid direct fuel cell technology with mud as fuel can realize efficient, the clean utilization of mud, is a new fuel cell technology the most promising.

The present invention relates to a kind of sludge fuel battery, directly mud can be converted into electric energy at low temperatures, fuel is made without any pretreatment.It is catalyst and charge carrier that the negative electrode of this sludge fuel battery and anode are respectively adopted different types of heteropoly acid (POMs), replace the noble metal catalyst in original fuel cell, finally achieve direct mud-electric energy liquid catalyst fuel cell technology (LCFC) of non precious metal.Owing to using heteropoly acid as catalyst, its stable performance, to impurity in fuel, as insensitive in element sulphur, nitrogen element etc., therefore mud is made without any pretreatment.
This fuel cell comprises two reaction tanks, is the heteropolyacid catalyst (POM-A) of anode and the heteropolyacid catalyst (POM-B) of sludge fuel and negative electrode and oxygen respectively.In anode reactor, first POM-A is reduced by mud, and meanwhile, POM-B is reduced at negative electrode, and the POM-B being reduced can be oxidized by oxygen regeneration.It practice, POM-A and POM-B is all as catalyst rather than reactant, because acid solution can be reproduced completely more than two kinds, there is no any mass loss.Therefore, the clean reaction of this fuel cell has related only to organic composition and the oxygen of mud.Concrete course of reaction can be divided into four steps:
The first step, POM-A solution is reduced by organic composition in mud the most in a heated condition in anode, and the electronics on organic matter is transferred to POM-A by organic matter；
Second step, makes reduction-state POM-A solution be recycled on graphite electrode plate by peristaltic pump, and now, electronics entrained on POM-A molecule is delivered to external circuit by graphite electrode, is eventually transferred into the POM-B of negative electrode.Meanwhile, proton is transferred to POM-B by film by POM-A.By whole process, the chemical energy in the mud organic matter being stored in is converted into electric energy, externally does work.
3rd step, the POM-B of oxidation state accepts external circuit electronics, is reduced to relatively low valence state, and electrode potential reduces.

Fig. 5 is under 80 DEG C, 100 DEG C and 150 DEG C of three different temperatures, through the 12 hours same response time, power-current density curve, comprehensive data above can illustrate that temperature is bigger with the impact of the extent of reaction of heteropoly acid on mud, under the identical response time, temperature is the highest, and the extent of reaction is the highest, and maximum power density is up to 63mW/cm2。
Fig. 6, under the conditions of constant current (220mA), determines fuel cell continuous discharge performance.The brown mud of 10g and 0.3mol/L 200ml phosphomolybdic acid being reacted 24 hours at 100 DEG C, after reacting liquid filtering, be placed in anode of fuel cell reaction tank, reaction temperature is 80 DEG C, and continuous discharge electric current density is 100mA cm-2, initial power density is 45mW cm-2, after continuous discharge 12 hours, power density is reduced to 30mW cm-2, continuing 23 hours whole discharge times, the solid after filtering carries out discharge test again, and initial power density is reduced to 30mW/cm2, whole discharge processes only continue for 4.5 hours.Subsequently, again remaining solid being carried out reacting by heating, then discharge, initial power is about 20mW/cm2, discharge time was less than three hours.Data above explanation was reacted through the first round, and most organic matter has the most all been dissolved in dissolving, and the organic matter fractions in remaining solid is less.
Fig. 7 is the brown mud of 10g and 0.3mol/L 200ml phosphomolybdic acid to be reacted 24 hours at 100 DEG C, by the solid residue of reaction after repeatedly rinsing, filtering, after being dried 12 hours, weighs, and carries out solid TOC test at 105 DEG C.Test result shows, the solid matter solution of first round reaction about 60% is in solution, and second takes turns quality decreases altogether about 80%, after terminating to third round reaction, and solid masses overall reduction 90%.The total carbon content of solid first drops, along with the carrying out of reaction presents, the rule risen afterwards, and this is owing to incipient stage substantial amounts of organic substance is dissolved in solution, and along with the inorganic matter that carries out of reaction also begins to dissolve in a large number, carbon content improves relatively.
