The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the diagram and the specific embodiment, further set forth the present invention.
As one of embodiment, pile up in the heat storage tank 100 low-temperature heat accumulating ball 130 is arranged, filled the lower phase-change material of phase transition temperature in the low-temperature heat accumulating ball 130, heat storage tank 100 internal upper parts are provided with heat taking and exchanging device 110, heat taking and exchanging device 110 is provided with heat-obtaining fluid inlet 111, the bottom is provided with Heat supply and heat exchange device 120 in the heat storage tank 100, and Heat supply and heat exchange device 120 is provided with heat donor fluid outlet 121; Pile up in the heat storage tank 200 high-temperature heat accumulation ball 230 is arranged, fill the higher relatively phase-change material of phase transition temperature in the high-temperature heat accumulation ball 230, heat storage tank 200 internal upper parts are provided with heat taking and exchanging device 210, heat taking and exchanging device 210 is provided with heat-obtaining fluid issuing 211, the bottom is provided with Heat supply and heat exchange device 220 in the heat storage tank 200, and Heat supply and heat exchange device 220 is provided with heat donor fluid import 221.
Between heat storage tank 100 and heat storage tank 200, heat taking and exchanging device 110 passes separately with heat taking and exchanging device 210 that the accumulation of heat tank wall is connected, and Heat supply and heat exchange device 120 passes separately with Heat supply and heat exchange device 220 that the accumulation of heat tank wall is connected.
Reach uniform temperature after the phase-change material heat absorption and undergo phase transition, constantly energy is stored.(this part fluid mainly comes from temporary transient no heat such as industrial waste heat, waste heat when the high temperature heat source fluid, and the temperature of this fluid will be higher than the phase transition temperature of phase-change material in the heat-storing sphere 230) enter from heat donor fluid import 221, during by Heat supply and heat exchange device 220 and Heat supply and heat exchange device 120, high temperature fluid and heat-storing sphere generation heat exchange, the phase-change material in high-temperature heat accumulation ball 230 and the low-temperature heat accumulating ball 130 is heated and undergoes phase transition heat accumulation.Because its phase transition temperature of phase-change material of filling in the high-temperature heat accumulation ball 230 is higher than the phase transition temperature of phase-change material in the low-temperature heat accumulating ball 130, the heat of heat donor fluid is absorbed temperature decrease to some degree behind the heats by high-temperature heat accumulation ball 230, low-temperature heat accumulating ball 130 then absorbs the remaining heat of heat donor fluid, energy is carried out cascade utilization, and heat energy reaches abundant absorption from right to left.Be higher than 150 ℃ in the heat extraction temperature especially, serviceability temperature is lower than under 70 ℃ the situation, absorbs through secondary, can fully absorb the heat extraction energy, guarantees to utilize to greatest extent energy.
Energy stores and to finish and when not having thermal source and can utilize, this device is just brought into play the effect of thermal source.The heat-obtaining fluid enters from heat-obtaining fluid inlet 111, by heat taking and exchanging device 110 and heat taking and exchanging device 210, heat-obtaining fluid and heat-storing sphere generation heat exchange, energy is passed to fluid by heat-storing sphere, realize the release of energy, constantly obtain the heating back and flow out for using from heat-obtaining fluid issuing 211.And, can make full use of the heat of storage at this moment owing to use two kinds of phase change heat storage materials, prolong the heat release time.
In heat-accumulating process; heat constantly increases; pressure in the heat storage tank also increases thereupon; the high pressure protector 112 and the high pressure protector 212 on the heat taking and exchanging device 210 that are arranged on the heat taking and exchanging device 110 just can play the effect of protecting heat storage tank and its interior arrangement, can not damage regenerative apparatus because of the increase of pressure.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-mentioned enforcement and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications and (as uses coil pipe and heat pipe intensified method instead; the principle method is similar to the phase transformation ball), these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
