The present invention utilizes the gas pressure vibration of thermic acoustic effect generation, drives the ionic liquid reciprocating motion by the gas-liquid coupling, and cutting produces electrical potential difference on electrode perpendicular to the magnetic line of force of its direction of motion, loads with lotus outside connecting and can export electric energy.
Existing magnetic fluid generating technology, liquid metal and plasma are two kinds of main working medium.The operating pressure height of liquid metal, and the working temperature height of plasma, this has limited the application of correlation technique to a certain extent.The present invention adopts the sound-driving magnetic fluid generating technology of heat, and working temperature is at first low than using plasma, can make full use of low-grade heat energy, has improved efficiency of energy utilization; And as the ionic liquid at room temperature that replaces coil in the conventional power generation usage device, owing to have good electrical conductivity, it is a kind of desirable magnetohydrodynamic generation medium, be used as liquid piston simultaneously and introduce the simple thermoacoustic engine that adopts gas working medium of tradition, make full use of the compressibility acoustic capacitance of gas and the high density mass inertia phonoreception of liquid, form gas-liquid two-phase working substance coupled vibrations system, optimized the acoustic impedance characteristic of system, can realize strengthening the sound oscillation and the conversion of heat sound of thermoacoustic engine, raising sound merit fan-out capability.And, when " zero " vapour pressure characteristic of ionic liquid at room temperature makes itself and the associated working of gas phase working medium, can not guarantee the long-term stability operation of system owing to gas phase working medium is polluted in evaporation.The present invention has simultaneously adopted loop dual-travel-wave heat sound-driving, can increase sound merit produce, thus the output that has increased electric energy.
With respect to the simple gas working medium of tradition, the gas-liquid two-phase working substance coupled vibrations is strengthened the mechanism of thermoacoustic engine sound oscillation can carry out qualitative interpretation according to the knowledge of resonant circuit.For series connection RLC (RLC resistance-inductance-capacitance) resonant circuit, resonance potential is proportional to the mould ω L of induction reactance, as seen helps to strengthen resonance potential by increasing inductance L; Thus,,, make full use of liquid, can strengthen the pressure oscillation in the thermo-acoustic engine system because of than the bigger bigger inertia phonoreception of bringing of gaseous mass density by introducing liquid piston according to electro-acoustical analogy.But, because resonance frequency
As seen when phonoreception L increases, the system resonance frequency will decrease.Therefore during system design, can not increase phonoreception simply strengthening pressure oscillation, need carry out balance with satisfying between the resonance frequency requirement strengthening pressure oscillation.With regard to essence, the gas-liquid coupled vibrations that the present invention adopts is by improving the acoustic impedance characteristic of thermo-acoustic engine system, strengthening the sound oscillation in the thermoacoustic engine, and then promote its electric energy fan-out capability.
For the thermoacoustic driving magnetohydrodynamic electricity generation system of employing ionic liquid at room temperature of the present invention, the frequency of thermoacoustic system vibration is the frequency of output voltage.In real work, the change of operating mode possibility, for example the working temperature of system, pressure and other parameters may fluctuate, and will cause the fluctuation of the resonance frequency and the output voltage frequency of system, this is normally disadvantageous for load, also is unfavorable for generating electricity by way of merging two or more grid systems.At above problem, in system, be provided with frequency regulator, mainly the pressure by regulating system guarantees the stable of frequency.Frequency regulator mainly is made up of two air reservoirs and corresponding adjuster valve, is equipped with heater and water cooling coil pipe on two air reservoirs.By heating and cooling down operation, guarantee that the operating pressure of an air reservoir is higher than the thermoacoustic system operating pressure, the pressure ratio thermoacoustic system pressure of another air reservoir is low.When the system works frequency is higher, open low pressure air reservoir adjuster valve; Otherwise then open high pressure air reservoir valve,, guarantee the stable of output voltage frequency to regulate the thermoacoustic system operating pressure.Its principle is that the acoustic capacitance of gas phase working medium parts such as the capable ripple heat of loop sound nuclear can have following formula estimation C=V/ (γ p
m) (V is a volume, and γ is a specific heat ratio, p
mBe average pressure), visible by regulating pressure, the acoustic capacitance of regulating system easily.According to C=V/ (γ p
m), when pressure increased, acoustic capacitance reduced, in conjunction with
As can be known, resonance frequency will increase thereupon; Otherwise when reducing operating pressure, resonance frequency also will decrease.As seen, can guarantee the stable of output voltage frequency, and then can make things convenient for electricity generation system to insert electrical network and need not add frequency adjustment equipment in addition by frequency stabilizing apparatus.
The present invention proposes to have the ionic liquid at room temperature introducing thermoacoustic system of " zero " vapor pressure properties, form the gas-liquid coupled vibrations with the gas working medium of heat sound nuclear part, utilize ionic liquid at room temperature reciprocating motion on the one hand with excellent conductive performance, the cutting magnetic line generating, on the other hand, strengthen sound oscillation and then promote the electric energy fan-out capability by the gas-liquid coupled vibrations.In addition, the invention allows for and utilize ionic liquid at room temperature to cut off the method for the gas circuit in the capable ripple heat of the loop sound nuclear, can effectively eliminate gas working medium and flow along the direct current that loop produces.
The thermoacoustic driving magnetohydrodynamic electricity generation system of employing ionic liquid at room temperature of the present invention, gas phase working medium can adopt natural mediums such as helium, nitrogen, argon, clean environmental protection.The attribute that should possess as the desirable ionic liquid at room temperature of liquid piston is: under the room temperature condition, the coefficient of viscosity is less, chemically stable, nontoxic, compatible with the structural material of gas working medium and thermoacoustic engine etc.Ionic liquid can adopt the dioxane imidazole ion liquid, as: trifluoromethanesulfonic acid 1-ethyl-3-methylimidazole [EMIM] [OTF], tetrafluoro boric acid 1-ethyl-3-methylimidazole [EMIM] [BF
4], trifluoroacetic acid 1-ethyl-3-methylimidazole [EMIM] [TFA] etc.
The filling of dashing from working medium begins the course of work of system is described below, introduces the adjustment process of output voltage frequency simultaneously.
Before dashing filling working medium, open two break valves, first and second air reservoir adjuster valves and filled valve earlier, by filling valve system is vacuumized; Subsequently, carry out the filling of dashing of ionic liquid working medium via filled valve, until reaching the design fill amount; After liquid filling finishes, carry out gas working medium via filled valve again and dash filling, until design fill pressure P 0, at this moment, need to open the water cooling coil pipe of first and second air reservoirs, the temperature constant that guarantees two air reservoirs is at room temperature T0.After finishing whole working medium filling process, close filled valve.
Then, close the second air reservoir adjuster valve, the gas working medium pressure in second air reservoir remains on P0, and temperature is T0, and second air reservoir becomes the low pressure air reservoir.Heater (thermal source can be gas heating, industrial waste heat, waste heat, solar energy etc.), open first and second water coolers simultaneously, set up temperature gradient along regenerator, rise to some extent owing near the gas working medium the heater is heated the system internal pressure of making simultaneously; When temperature gradient surpasses the critical temperature gradient, system begins to take place thermal acoustic oscillation, and progressively reach steady-working state, this moment, ionic liquid moved reciprocatingly in resonatron, the magnetic line of force that cutting is formed by permanent magnet perpendicular to the ionic liquid direction of motion, thereby on electrode, produce electrical potential difference and realize generating, at last by two pigtail splice output electric energy.When system reached steady-working state, the power pressure that the average working pressure of system has risen in design work pressure P 1, the first air reservoir also reached P1 (P1 is greater than P0).At this moment, close the first air reservoir adjuster valve, close the water cooling coil pipe of first air reservoir, open the heater (thermal source can be gas heating, industrial waste heat, waste heat, solar energy etc.) on first air reservoir, the temperature increase that makes gas working medium wherein is to design load T2, the corresponding P2 (P2 is greater than P1) that further is elevated to of pressure makes first air reservoir become the high pressure air reservoir simultaneously.As seen, when setting up the electricity generation system steady operation, made the air reservoir pressure P 2 of winning be higher than thermoacoustic system average working pressure P1, and the second air reservoir pressure P 0 is lower than thermoacoustic system average working pressure P1, realizes frequency adjustment for frequency regulator and get ready.In addition, after closing the first air reservoir adjuster valve, close two break valves, with frequency regulator and the filled pipeline of working medium and the thermoacoustic system partition of formations such as air reservoir, the sound merit that causes to avoid working medium in this part pipeline, to vibrate loss.
In the Blast Furnace Top Gas Recovery Turbine Unit (TRT) that the present invention proposes, the frequency of oscillation of thermoacoustic system is the frequency of output voltage, because the fluctuation of driving heat source etc. may cause the temperature of heater and the variation of system's average working pressure, and then causes the fluctuation of thermoacoustic system frequency of oscillation and output voltage frequency.The frequency regulator that the present invention proposes can change the adjusting that system's average working pressure is realized frequency by charging and discharging gas working medium to thermoacoustic system.Specifically, be higher than thermoacoustic system average working pressure P1 in the above-mentioned first air reservoir pressure P 2, and the second air reservoir pressure P 0 is lower than under the state of thermoacoustic system average working pressure P1, if frequency is lower than design load, then open two break valves and the first air reservoir adjuster valve, make portion gas working medium enter thermoacoustic system from first air reservoir, promote the wherein average working pressure of gas working medium, and make resonance frequency raise, until design frequency, close two break valves and the first air reservoir adjuster valve afterwards, stop to regulate.If frequency is higher than design load, can be by opening two break valves and the second air reservoir adjuster valve, make the gas working medium in the thermoacoustic system under the driving of pressure reduction, flow into second air reservoir, because the effect of cooling coil, the temperature of second air reservoir remains at T0, and the resonance frequency of thermoacoustic system will reduce to reduce because of the gas working medium average working pressure, until the design work frequency, close two break valves and the second air reservoir adjuster valve afterwards, stop to regulate.After work a period of time, first air reservoir is because the effect of heater, and its temperature can still remain on high temperature T2, but pressure will constantly be emitted and reduce the average working pressure of convergence thermoacoustic system owing to working gas; And second air reservoir is because the effect of water cooling coil pipe, and its temperature still can remain on room temperature T0, but pressure will raise the average working pressure of convergence thermoacoustic system owing to working gas constantly flows into.When the pressure of two air reservoirs reaches the average working pressure of thermoacoustic system, air reservoir will lose the regulating power to thermoacoustic system gas working medium average working pressure, at this moment, need its regulating power of regeneration.Specifically, under the condition that two break valves and the first and second air reservoir adjuster valves are all closed, close the heater of first air reservoir, open its water cooling coil pipe, its temperature is reduced to T0 from T2, thereby can makes its pressure drop to the average working pressure that is lower than thermoacoustic system and become the low pressure gas storehouse from the average working pressure of thermoacoustic system; On the other hand, close the water cooling coil pipe of second air reservoir, open its heater, its temperature is increased to T2 from T0, thereby can make its pressure be increased to the average working pressure that is higher than thermoacoustic system and become the high pressure gas storehouse from the average working pressure of thermoacoustic system.As seen, such operation has realized the conversion of high-low pressure air reservoir between first air reservoir and second air reservoir, the frequency regulation capability of the frequency regulator of having regenerated.And so forth, can guarantee the permanently effective operation of frequency regulator.
In addition, the present invention utilizes the gas circuit in the capable ripple heat of the ionic liquid at room temperature partition loop sound nuclear, therefore the charging amount of ionic liquid at room temperature must be full of the bottom of whole resonatron and the capable ripple heat of loop sound nuclear, and keep certain liquid level, to guarantee that in the device running vibration of liquid level is unlikely to destroy the partition effect of fluid column to row ripple heat sound nuclear ring road.
