Abstract
The utility model relates to a sound eliminator, in particular to the sound eliminator used for the tail gas discharging in the chemical engineering field and the sound eliminator used for the gas discharging with large flow and high pressure in other fields. The tail gas discharging sound eliminator of a chemical engineering device comprises a barrel body, one end of the barrel body is provided with an air inlet, the other corresponding end of the barrel body is provided with an air outlet, the air inlet is connected with a tail gas discharging pipe, the cross-sectional area of the passage of the barrel body is larger than the cross-sectional area of the tail gas discharging pipe, at least a conical passage plate is arranged in the barrel body, the bottom surface of the conical passage plate is in coincided with the cross section of the barrel body and is close to the air inlet, and passage holes are arranged at the periphery of the conical passage plate by taking the axis of the conical passage plate as a symmetrical center; and a sound absorption cover is arranged at the outer part of the air outlet of the barrel body. In the tail gas discharging sound eliminator of the chemical engineering field, the tail gas crash mutually after baffling through the conical passage plate, most of the energy is offset and then is baffled to be discharged after sound adsorption of the sound absorption cover, thereby greatly eliminating the noise.
Description
Technical field
The utility model relates to silencing apparatus, further is meant silencing apparatus or the used silencing apparatus of other field flow gaseous emission big, that pressure is high that the chemical field exhaust emissions is used.
Background technique
Modern chemical industry is produced the hydrogen peroxide technology process years of development like chemical industry for making chlorine and alkali, and technology is constantly improved, and device is to large-scale, low consumption development, but the displacement noise of tail gas is very big.Because of hydrogen peroxide oxidation tail gas through the calm the anger end output discharging of worm gear decompressor, 60kt/a hydrogen peroxide plant exhaust emissions pressure is 0.05MPa, the processing flow is 10000Nm
3/ h, as handling without eliminating the noise, its noise does not still reach environmental requirement as handling through traditional silencing apparatus more than 120db, and environmental requirement is: be lower than 50db daytime, be lower than the 40db discharging evening.
Conventional muffler conventional muffler design lays particular emphasis on sound-absorbing, and the boundary dimension of silencing apparatus can be very greatly very long, and silencing apparatus contacts with aggressive medium entirely, and it is 304 that material will be demanded perfection, and cost is understood corresponding increase.
Summary of the invention
The purpose of the utility model is the deficiency to existing technology, and a kind of chemical plant installations exhaust emissions silencing apparatus is provided, and noise reduction efficacy is high, and volume is few, and cost is low, can satisfy environmental requirement fully.
The technological scheme of the utility model is that a kind of chemical plant installations exhaust emissions silencing apparatus comprises cylindrical shell; Cylindrical shell one end is a suction port, and the corresponding the other end is the air outlet, and suction port links to each other with tail gas discharging pipe; It is characterized in that; Said cylindrical shell channel cross sectional area is greater than the cross sectional area of tail gas discharging pipe, and is provided with at least one tapered channel plate in the cylindrical shell, and said tapered channel plate bottom surface overlaps with the cylindrical shell cross section; And tapered channel plate bottom surface is near suction port, and tapered channel plate periphery is offered port hole with tapered channel plate axis symmetry; Outside, cylindrical shell air outlet is provided with sound absorption cover.
Below the utility model is further described.
Further, said tapered channel plate comprises that the longitudinal section drift angle is the tapered channel plate of 150 ° of 90 ° tapered channel plate, tapered channel plate that the cross section drift angle is 120 ° and cross section drift angles.
Further, said three blocks of tapered channel plates are followed successively by the tapered channel plate of 150 ° of tapered channel plate, cross section drift angles of 90 ° of tapered channel plate, the cross section drift angles of 120 ° of cross section drift angles from suction port to air outlet.
As shown in Figure 1, A, B are any two groups of symmetry gases, the final symmetrical chiasma gas that forms behind the channel plate baffling, and quite a few cancels out each other energy, and noise becomes about 65db.
For further reducing noise, to reach the environment protection emission requirement, outside baffler, increase sound absorption cover again, the sound absorption cover liner adopts the damping sound absorbing material, and the energy of tail gas is further absorbed, and to the sky discharging, the noise decibel value is lower than 40, reaches environmental requirement fully then.
Known that by above the utility model is as a kind of chemical plant installations exhaust emissions silencing apparatus, run foul of each other after making the tail gas baffling through the tapered channel plate that energy is most of offsets, through the baffling discharging again of sound absorption cover sound-absorbing, noise is eliminated greatly.
