Method for optimizing muffler structure by immunoassay

The invention relates to a method for optimizing the structure of a silencer by an immunoassay method, in particular to a four-dimensional transfer matrix method with a one-dimensional plane wave (low-order wave) combined with an immunoassay method for performing a full-range silencer. The optimal operation analysis of the variable design parameters is to quickly and effectively seek the optimal solution of the numerical values of the parameters, so as to effectively eliminate the compressor (engineering), the exhaust pipe of the engine and the pressure relief pipe (mouth), etc. The noise generated by the exit.

According to the sound wave, the sound wave is a form of sound propagation. The sound wave can be transmitted by gas, liquid and solid, and its transmission mode includes reflection, refraction, diffraction, etc.; due to the development of scientific and technological civilization, life is full of various noises, such as vehicles. Engine noise, horn sound, aircraft or air-conditioning compressors, etc. Excessive noise often seriously affects emotions and destructs the quality of life, especially in process equipment factories, because most of the sound sources are intake and exhaust noise, for low-frequency characteristics. Equipment (such as air compressors, diesel engine generators, etc.) must rely on a silencer with superior sound attenuation characteristics; in addition, for example, the exhaust gas generated by the engine after combustion of the fuel, if directly discharged into the atmosphere, will cause The gas pressure of the exhaust gas is suddenly reduced from high pressure to atmospheric pressure, which produces very harsh noise. Therefore, the exhaust gas must pass through the silencer, so that the pressure and frequency of the exhaust gas become smaller, so as to effectively reduce the exhaust noise. Others have the basement of the building. Generator rooms, machine rooms, factories and other places are also the source of most noise, and The sound is one of the noise prevention methods. The principle is mainly to reduce the volume by the absorption, reflection and interference of the sound. In general, the silencer is mostly used in the compressor, the engine row (replacement), and the pressure. The sound is quickly silenced by the gas discharge pipe (mouth).

At present, the existing silencers can be roughly divided into four types: (a) straight tube type: like a general air duct, which is attached to the sound absorbing material in the tube, and uses the sound absorbing principle to absorb the noise of the airflow; (b) twists and turns Type: similar to straight tube silencer, but to increase the degree of turning to improve the sound absorption area, and use the destructive interference of the wave to reduce the sound energy, enhance the effect of silence; (c) expansion type: straight tube type as the basic type However, changing the cross-sectional area of the ventilation, the use of the two-pipe joints with different cross-sectional areas increases the reflection of the sound energy, so that the sound is converted at different stages due to the change of space to achieve the effect of sound-absorbing; d) Resonance: A resonance chamber is made for certain frequencies to make the sound resonate to achieve energy reduction.

However, at present, the effective control of the control and research on the process equipment is only improved in the structure of the muffler, the addition of the muffler equipment or the muffling material, and the design parameters of the muffler are limited to the discussion of a single variable. Therefore, the lack of flexible design and optimization ability, the design of the silencer can only be carried out in a trial and error manner, not only the structural design changes are limited, but also the design parameters cannot be modulated; therefore, a systematic, The holistic, multi-variable design parameters of the optimized muffler structure method to control the noise generated by process equipment, compressors, engines and other equipment is indeed necessary.

Nowadays, the inventor has in view of the above-mentioned existing methods for reducing the noise generated by the rapid import and export of gas in mechanical equipment, and still has many defects in practical implementation, so it is a tireless spirit and with its rich professional knowledge.
