Description
Technical field
The present invention relates to a kind of refrigeration system, particularly relate to a kind of novel acoustic resonance type heat activated traveling wave thermoacoustic refrigeration system.
Background technology
Along with the application of high-temperature superconductor, superconducting transformer, superconducting generator, cryomotor, hyperconductive cable, current limiter, superconducting energy storage etc. have obtained development fast, and this raising to Cryo Refrigerator refrigerating capacity has proposed further requirement.Also there are some still an open questions in high-power pulse tube refrigeration machine at present, due to the increase of size, is easy to cause gas flow and temperature distributing disproportionation, and power is difficult to further improve, and also there is no at present good solution.Along with day by day consuming of oil and coal resources and increasingly sharpening of environmental pollution thereof, increasing the ratio of natural gas in primary energy becomes the important channel of China's Optimization of Energy Structure on the other hand.Compared with pipe natural gas, liquefied natural gas LNG is conducive to long distance transportation and storage, is conducive to the recovery of outlying natural gas, reduces the storage cost of natural gas, is conducive to the peak regulation in natural gas applications.Traditional natural gas liquefaction flow process mainly contains following three kinds: superposition type liquefaction flow path, mixed working fluid liquefaction flow path, liquefaction flow path with decompressor, any liquefaction flow path is all comprising the process of many complexity, and this province of working medium using just exists the disagreeableness problem of environment.
Traveling wave thermoacoustic engine and vascular refrigerator be because it has reliable, long service life, potential efficiency advantages of higher gets more and more people's extensive concerning, and drives the complete movement-less part of vascular refrigerator feasible system with traveling wave thermoacoustic engine.The conversion of hot acoustic energy is decided by the phase difference between pressure oscillation and volume flow rate fluctuation to a great extent.Volume flow rate can be expressed as with the traveling-wave component of pressure oscillation homophase and with the standing wave sum of 90 ° of pressure oscillation phase phasic differences, pure standing wave is that the phase difference of pressure oscillation and volume flow rate can not generation sound merit while being 90 °, the generation of sound merit is by traveling-wave component, be the synchronous component of pressure oscillation and volume flow rate, therefore make traveling-wave component in sound field increase and there is positive meaning to improving hot sound mechanical switch efficiency as far as possible.
The Ceperley of the U.S. in 1979 has proposed the concept of traveling wave thermoacoustic engine first, but owing to not proposing the effectively technical scheme of reduction to the limited of Sonic heat changing mechanism understanding and to reducing the impedance of traveling wave thermoacoustic engine generation hot merit conversion core component regenerator, therefore do not develop the traveling wave thermoacoustic engine that can work.
1998, at the beginning of traveling wave thermoacoustic engine development, the people such as Yazaki, Iwata of Japan has proposed ring pipe traveling wave thermoacoustic engine, as shown in Figure 1, they adopt LDV to measure working gas hunting speed in experiment, and recognize because the folded place of engine plate working gas hunting speed is larger, have caused serious viscosity loss, limit the efficiency of traveling wave thermoacoustic engine, but do not proposed adequate solution scheme.
Subsequently, the hot acoustic Stirling heat engine that the people such as Backhaus and Swift of the U.S. proposes and the thermoacoustic engine of some similar structures, introduce resonatron structure, as shown in Figure 2, although be greatly improved in systematic function, but resonatron part is still substantially take standing-wave sound field as main, thermoacoustic engine greatly sound merit dissipates in resonatron, and the introducing of resonatron greatly reduces the power density of system.
2010, the Kees de Blok of Holland has proposed the hot sound generator of a kind of novel 4 rank row ripple, people's ring pipe traveling wave thermoacoustic engines such as its structure and Yazaki are similar, but increase the area of regenerator, as shown in Figure 3, working gas hunting speed is effectively reduced in regenerator, solved the problem of viscosity loss in people's ring pipe traveling wave thermoacoustic engine regenerators such as Yazaki.But in thermoacoustic engine and for adding thermal buffer tube structure, can cause cold and hot gas losses by mixture, produce great heat exchange irreversible loss; And do not add the device of the suppression loop direct currents such as film in cyclic system, the direct current in loop can cause the directed flow of gas in system, make the heat transfer effect variation of gas converting heat and regenerator, heat exchanger, affect greatly hot acoustic performance.So this structure does not obtain good result yet yet.
2012, physics and chemistry Suo Luoercang seminar of the Chinese Academy of Sciences proposed double acting flow process, as shown in Figure 4, thermoacoustic engine or vascular refrigerator and the double acting linear electric motors formation loop that joins end to end, system can recovery sound merit, has improved greatly efficiency.But the introducing of double acting motor has increased system problem of inconsistency, when one of them motor and other motors are when variant, this species diversity can be exaggerated the performance that finally has influence on system in loop.
The present invention is the problem based on existing in the thermoacoustic engine with resonatron, loop traveling wave thermoacoustic engine and double acting thermoacoustic engine above just, a kind of novel design has been proposed, solved the problem that regenerator place resistance is excessive and resonatron volume is excessive, solve again the problem such as cold and hot loss, loop direct current occurring in DeBlock cyclic system, also solved the problem of inconsistency in double acting system simultaneously.Drive hot sound refrigerating machine can make system there is no moving component completely by thermoacoustic engine, further improve reliability, and can realize large cold output according to demand series connection multiple hot sound unit of cold, extremely be suitable for being applied in the occasion of large refrigeration requirement, such as the occasion such as low-temperature superconducting and natural gas liquefaction.In addition thermoacoustic engine hot junction cocoa utilizes the low-grade energies such as solar energy, industrial waste heat or combustion of natural gas used heat as its thermal source, has improved greatly energy utilization rate, has good utilization prospect in natural gas liquefaction direction.
Summary of the invention
The object of the present invention is to provide a kind of acoustic resonance type heat activated traveling wave thermoacoustic refrigeration system, utilize thermoacoustic engine to drive vascular refrigerator, the complete movement-less part of the system that realizes, can greatly improve the reliability of system; The invention has the advantages that in system loop, traveling-wave phase all can be realized in each position, improve system works efficiency; And can realize the required large cold output of natural gas liquefaction according to demand series connection multiple hot sound unit of cold; Loop acoustic resonance refrigeration system is except having flexibly advantage easily, more has concurrently simple in structurely, reliable, and the advantage such as potential efficiency is high, working medium environmental protection, has good application prospect in large refrigeration requirement occasion.
