Abstract
The utility model provides a noise silencer, comprising a tower body, a noise absorbing layer arranged on the inner wall of the tower body, a sound silencing folded plate and a sound silencing pore plate which are provided with micro pores and arranged in the tower body. The noise silencer is characterized in that the middle lower part of the interior of the tower body is arranged as a sedimentation area. A dust removal sound silencing sleeve pipe is provided with a plurality of pores and arranged in the sedimentation area. The bottom of the tower body is provided with a scum pipe and a sound silencing cylinder of the scum pipe. The dusty air entered the tower body is first parted out through the dust removal sound silencing sleeve pipe and the sedimentation area. The noise silencer effectively prevent that the dust clogs the pores or gaps on the micro pore plate and the noise absorbing material. The noise silencer not only eliminate the annoying noise, but also solves the problem of the existing safety hazard in the prior art. The noise silencer can completely satisfy the working environment of-180 degrees C-+80 degrees C and maintain well and silencing effect for a long time. The value of the silencing noise reduction is <=65lep(A). The structure is simple, and the service life is long. The noise silencer can be used as a specific silencing device when discharging the dusty air.
Description
Technical field
The utility model relates to a kind of quieter, especially a kind of device of eliminating the noise that is produced when dusty gas discharges.
Background technology
Existing system oxygen technology is to adopt low temperature process to come separation of air to produce oxygen, according to the requirement of production technology, when going into operation and stop production, must purge regenerator with pressure-air, to remove powder and the impurity on the heat-storing material in the regenerator.Owing to be that pressure-air purges, and pass through a valve to the airborne release pressure-air, so when purging regenerator, produced strong noise, purge time usually continues tens hours again, to several square kilometres the serious interference of environment generation on every side, normal office, teaching and life and rest have been influenced.Regenerator is when going into operation and stop production, experience-180 ℃～+ 80 ℃ temperature change, and dust such as the basalt stone powder in the regenerator, moisture, carbon dioxide are when rising with air-flow, very easily will have in the quieter hole plug on the acoustical panel now, also cause wearing and tearing simultaneously to quieter material, make quieter lose due sound deadening, even also can split because of obstruction causes that the tower wall exposes to the sun, thus the potential safety hazard of burying.Therefore, be necessary prior art is improved.
Summary of the invention
The utility model is exactly for solving above-mentioned high pressure, the noise of low wet and a kind of noise quieter that the dust blockage problem designs.
The utility model is realized by following technical proposal: it comprises tower body, be located at the sound absorbing layer of tower body inwall, be located at the noise reduction flap and the noise reduction orifice plate that have micropore in the tower body its, it is characterized in that the middle and lower part in the tower body is made as between sedimentation, be provided with the dedusting noise reduction sleeve pipe of opening porous on it between sedimentation, the tower body bottom is provided with scum pipe and hush pipe thereof.
Described dedusting noise reduction sleeve pipe is made of interior pipe and outer tube, and on the pipe, interior pipe passed the tower wall and outwards extends in outer tube was placed in, aperture on the inner and outer pipe tube wall is 5-6mm,, in the hole, flow between sedimentation during sleeve pipe so that gas with dust is flowed through, make dust at the bottom of the deadweight effect falls into tower.
The hush pipe of described tower body bottom is enclosed within on the scum pipe, so that the sound deadening when further strengthening deslagging.
This novel practical is novel compared with prior art to have following advantage and effect: the utility model is arranged to the noise reduction dedusting section of bottom and the noise reduction section on top with tower body inside, the gas with dust that enters tower body is separated through between dedusting noise reduction sleeve pipe and sedimentation in advance, effectively prevent hole or crack on blocking microporous plate of dust and the acoustical material, and the dust that in tower body, settles down, moisture etc., then discharge through scum pipe and hush pipe, both eliminated the noise of disturbing the people, the problems such as potential safety hazard that prior art exists have been solved again, the utility model can satisfy-180 ℃～+ 80 ℃ working environment fully in addition, keep good, permanent erasure effect, make sound-deadening and noise-reducing value≤65lep (A), therefore, be a kind of simple in structure, long service life, noise reduction, the noise quieter of good dedusting effect, the special-purpose quieter when it can be used as the discharging dusty gas.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure, 1 is the blast cap at tower body top, 2 is the pugging in the tower body, 3 for being arranged at the acoustical material in the pugging, 4 is the noise reduction flap of tower internal upper part, which is provided with many micropores 11,5 is the micro silencer plate at middle part in the tower, be positioned at the bottom of noise reduction flap 4,6 for the interior pipe of noise reduction sleeve pipe, the one end places in the tower body, the other end passes the tower wall and outwards extends, so that link to each other with air shooter, place the tube wall in the tower body to be provided with the through hole 14 that a plurality of apertures are 5-6mm, 7 for the outer tube of noise reduction sleeve pipe, on the pipe 6, the through hole 14,8 that is provided with a plurality of apertures on its tube wall equally and is 5-6mm be the thermofin bottom the tower body in being sleeved on, 9 is the scum pipe at the bottom of the tower, 10 is hush pipe, and 12 is tower body, and 13 is between the sedimentation of middle and lower part in the tower body, gas with dust enters from the interior pipe 6 of noise reduction sleeve pipe, 14 outer tubes 7 that enter the noise reduction sleeve pipe through the hole 14 flow between sedimentation 13 through the hole again, the moisture in this moment gas, dry ice, the basalt stone particle, the carbon dioxide dry powder particle is separated between sedimentation, be deposited on the thermofin 8, discharge by scum pipe 9 and hush pipe 10.Gas after the dedusting rises and is discharged into atmosphere by micro silencer plate 5, noise reduction flap 4 after further eliminating the noise.
Claims (3)
1, a kind of noise quieter, comprise tower body, be located at the sound absorbing layer of tower body inwall, be located at the noise reduction flap and the noise reduction orifice plate that have micropore in the tower body its, it is characterized in that the middle and lower part in the tower body is made as between sedimentation, be provided with the dedusting noise reduction sleeve pipe of opening porous on it between sedimentation, the tower body bottom is provided with scum pipe and hush pipe thereof.
