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. obtain and develop fast, and this proposes further requirement to the raising of Cryo Refrigerator refrigerating capacity.Also there are some still an open questions in current high-power pulse tube refrigeration machine, due to the increase of size, be easy to cause gas to flow and temperature distributing disproportionation, power is difficult to improve further, does not also have good solution at present.On the other hand along with oil and day by day consuming of coal resources and increasingly sharpening of environmental pollution thereof, increase the important channel that the ratio of natural gas in primary energy becomes China's Optimization of Energy Structure.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: the liquefaction flow path of superposition type liquefaction flow path, mixed working fluid liquefaction flow path, band decompressor, any liquefaction flow path all contains the process of many complexity, and this province of working medium used just also exists the disagreeableness problem of environment.
Traveling wave thermoacoustic engine and vascular refrigerator get more and more people's extensive concerning because it has reliable, long service life, potential efficiency advantages of higher, drive the complete movement-less part of vascular refrigerator feasible system with traveling wave thermoacoustic engine.The conversion of hot acoustic energy be decided by a great extent pressure oscillation and volume flow rate fluctuate between phase difference.Volume flow rate can be expressed as and the traveling-wave component of pressure oscillation homophase and the standing wave sum with pressure oscillation phase 90 °, sound merit can not be produced when the phase difference of pure standing wave and pressure oscillation and volume flow rate is 90 °, the generation of sound merit is by traveling-wave component, i.e. pressure oscillation and the synchronous component of volume flow rate, therefore makes traveling-wave component in sound field increase as far as possible and has positive meaning to raising Thermoacoustic devices conversion efficiency.
The Ceperley of the U.S. in 1979 proposes the concept of traveling wave thermoacoustic engine first, but producing to reducing traveling wave thermoacoustic engine the technical scheme that the impedance of heat to power output core component regenerator do not propose effectively to reduce due to understand Sonic heat changing mechanism limited, therefore not developing 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 propose ring pipe traveling wave thermoacoustic engine, as shown in Figure 1, they adopt LDV to measure working gas hunting speed in an experiment, and recognize because engine plate folded place working gas hunting speed is comparatively large, cause serious viscosity loss, limit the efficiency of traveling wave thermoacoustic engine, but do not propose adequate solution scheme.
Subsequently, the thermoacoustic engine of the thermoacoustic machine heat engine that the people such as Backhaus and Swift of the U.S. propose and some similar structures, introduce resonatron structure, as shown in Figure 2, although be greatly improved on system performance, but resonatron part is still substantially based on standing-wave sound field, thermoacoustic engine greatly sound merit dissipates in resonatron, and the introducing of resonatron greatly reduces the power density of system.
2010, the KeesdeBlok of Holland proposes the hot sound generator of a kind of novel 4 rank row ripple, its people such as structure and Yazaki ring pipe traveling wave thermoacoustic engine is similar, but be increased the area of regenerator, as shown in Figure 3, working gas hunting speed is effectively reduced in regenerator, solves the problem of viscosity loss in people's ring pipe traveling wave thermoacoustic engine regenerators such as Yazaki.But in thermoacoustic engine, do not add thermal buffer tube structure, cold and hot gas and vapor permeation can be caused to lose, 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 gas converting heat and regenerator, the heat transfer effect of heat exchanger is deteriorated, have impact on hot acoustic performance greatly.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, and as shown in Figure 4, thermoacoustic engine or vascular refrigerator and double acting linear electric motors join end to end formation loop, and system can reclaim sound merit, greatly improves efficiency.But the introducing of double acting motor adds system problem of inconsistency, when one of them motor and other motors variant time, this species diversity can be exaggerated the performance finally having influence on system in the loop.
The present invention is just based on Problems existing in the thermoacoustic engine of above band resonatron, loop traveling wave thermoacoustic engine and double acting thermoacoustic engine, propose a kind of novel design, namely the problem that regenerator place resistance is excessive and resonatron volume is excessive is solved, solve again in DeBlock cyclic system the problem such as cold and hot loss, loop DC occurred, also solve the problem of inconsistency in dual acting system simultaneously.Drive hot sound refrigerating machine that system can be made not have moving component completely by thermoacoustic engine, further increase reliability, and High cooling power can be realized according to the multiple hot sound unit of demand series connection of cold to export, extremely be suitable for the occasion being applied in High cooling power demand, such as the occasion such as low-temperature superconducting and natural gas liquefaction.In addition thermoacoustic engine hot junction can utilize the low-grade energies such as solar energy, industrial waste heat or combustion of natural gas used heat as its thermal source, greatly improves 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, greatly can improve the reliability of system; The invention has the advantages that in system loop, each position all can realize traveling-wave phase, improve system works efficiency; And the High cooling power that can realize needed for natural gas liquefaction according to the multiple hot sound unit of demand series connection of cold exports; Loop acoustic resonance refrigeration system is except having flexibly advantage easily, and more have structure concurrently simple, reliable, the advantages such as potential efficiency is high, working medium environmental protection, have good application prospect in High cooling power demand occasion.
