Embodiment
A kind of noise Blast Furnace Top Gas Recovery Turbine Unit (TRT), comprise acoustic-electric converter 10, described acoustic-electric converter 10 comprises coil 11, with the magnet 12 of coil 11 corresponding settings and be used for the perception sound wave and vibrative vibrating diaphragm 13, a be laid in end of coil 11 of vibrating diaphragm 13, coil 11 other ends are positioned at the magnetic line of force scope of magnet 12, described coil 11 connects external equipment by output line 14, the noise Blast Furnace Top Gas Recovery Turbine Unit (TRT) also comprise can and sound wave between the resonating tube 20 of empathizing, described acoustic-electric converter 10 is fixed in a wherein end of resonating tube 20, and its vibrating diaphragm end points to resonating tube 20 inner chambers.
As everyone knows, a key property of sound resonates exactly, and resonance also claims " sympathetic response " in acoustics, and it refers to the phenomenon of object because of the resonance sounding, and close as the tuning fork that two frequencies are identical, during one of them vibration sounding, another also can sounding.Air in the air column also can be caused sympathetic response by acoustical vibration.Take a sound producing body to get close to vessel port, if frequency or wavelength are suitable, air column will play sympathetic response so, and makes loud big reinforcement.Scientist discovers, as long as wavelength equals 4 times of air column length, or 4/3,4/5 ... sound, just can cause the wherein sympathetic response of air after importing the container of relative closure into.Technique scheme of the present utility model is " resonance " characteristic of using for reference sound wave, and extraneous sound wave after resonating tube 20 carries out the acoustic resonance amplification, is imported into vibrating diaphragm 13 places of acoustic-electric converter 10 and finally is converted into electric energy by acoustic-electric converter 10.
Further, better for the sound wave sympathetic response effect that makes resonating tube 20, shown in Fig. 1-2, described resonating tube 20 profiles are the straight bobbin shape of end sealing, and described acoustic-electric converter 10 is positioned at the pipe bottom of resonating tube 20.
As further preferred version of the present utility model: as shown in Figure 1, the noise Blast Furnace Top Gas Recovery Turbine Unit (TRT) also comprises with resonating tube 20 mouths of pipe and is communicated with the sound collector 30 that is provided with, and described sound collector 30 profiles are horn-like, and its small end is communicated with and is fixed in the mouth of pipe place of resonating tube 20.Sound collector 30 herein can be concentrated, amplify the sound wave acoustic pressure effectively, and the external world is loose, the noise channeling conduct of dispersing is collected and is converted into intensive sound wave and transmits in the resonating tube 20 again, thereby generating efficiency of the present utility model is further promoted.
Further, sound wave also has a key property to be " reflection " characteristic of sound wave except above-mentioned " resonance " characteristic, that is to say that sound wave can reflect and reflect when running into object.Utilize the above-mentioned characteristic of sound wave, the utility model is vibrating diaphragm 31 outside sound collector 30 inwalls are laid with, described outer vibrating diaphragm 31 by sound collector 30 large port places to resonating tube 20 mouth of pipe places that the are positioned at sound collector 30 small ends transition of postponing.Outer vibrating diaphragm 31 itself promptly forms best acoustic reflection face by sound collector 30 large port places after transition is postponed at resonating tube 20 mouth of pipe places that are positioned at sound collector 30 small ends, when ambient noise enters sound collector 30, sound wave constantly vibrating diaphragm 31 surface reflections outside also finally enters in the resonating tube 20 along its reflecting surface, thereby has greatly increased operating efficiency of the present utility model.Simultaneously, described outer vibrating diaphragm 31 is for leaving the gap between elastic membrane and itself and sound collector 30 inwalls, such scheme has been strengthened the reflection dynamics of 31 pairs of sound waves of outer vibrating diaphragm on the one hand, leave the gap between outer on the other hand vibrating diaphragm 31 and sound collector 30 inwalls and also be the vibration propagation of sound wave itself of being more convenient for, thereby provide assurance by the reliable delivery of the external world for sound wave to inside.
Further, be suspected to be maximumly because its amplitude of vibrating diaphragm 13 centers is not ccontaining, therefore, as shown in Figure 3, the coil 11 of described formation acoustic-electric converter 10 is fixed in vibrating diaphragm 13 centers.In addition, for increasing the utility model generating efficiency, described acoustic-electric converter 10 is a plurality of and is distributed in resonating tube 20 pipe bottoms.
The utility model carries out actual experiment and measurement again through preproduction model, and its generating efficiency is high, and concrete experiment measuring numerical value is as follows:
Experiment place: the room of indoor 18 square meters.
Experiment condition: 20 ℃ of temperature, average pressure are a standard atmospheric pressure.
