Abstract
The utility model relates to a novel multi-tube steam-air emptying silencer which comprises a base (1), a casing (2) and a multistage pressure reducing tube, wherein the casing is in a micro-hole plate sandwich structure. Multiple tubes are concentrically sheathed to form the multistage pressure reducing tube, and the wall of the tube is provided with a pressure reducing hole. The utility model which conforms to international requirements has the advantages of pressure reduction depending on steam and air expansion, good effects on sound absorption and sound attenuation, long service life and easy operation, and a ZX series of steam-air emptying silencers are successfully developed.
Description
The utility model belongs to environmental protection machinery, and mainly is meant a kind of novel multitube silencing apparatus that industrial environment steam, air emptying noise are used that is suitable for eliminating.
Before the utility model, that knows altogether is used for steam, air emptying gas mufflers such as boiler, steam turbine, steam generator, steam pipe system and air-pressure equipment, its structural type is two garden tube micropore decompression silencing apparatuss, because steam, air are only by two layers of vent decompression emptying, there is not other measure, so it is not thorough that steam, air expansion are reduced pressure, and makes the noise elimination effect undesirable.
Goal of the invention of the present utility model provides a kind of novel steam, air emptying silencing apparatus, and its employing multi-step pressure reduction pipe decompression is eliminated the noise, and the interlayer shell sound-absorbing that the band microwell plate is set is eliminated the noise, and reaches purpose scientific and reasonable for structure, that noise elimination is effective.
The technical solution of the utility model is: novel multitube steam, air emptying silencing apparatus, comprise base (1), shell (2) and multi-step pressure reduction pipe (3) three parts, shell (2) is a upper shed garden cylindrical shell, barrel sandwich structure, and its inwall microwell plate (5) is distributed with micropore (8); Multi-step pressure reduction pipe (3) is managed concentric suit by 1-10 garden and is constituted, and each manages sealing suitable for reading, and tube wall is distributed with vent (9).
The technical program has adopted the multitube multi-step pressure reduction to eliminate the noise, and adopts the further sound-absorbing of interlayer shell of band microwell plate to eliminate the noise, and has improved the noise elimination effect effectively.

Description of reference numerals: base (1), shell (2), multi-step pressure reduction pipe (3), outer sleeve (4), microwell plate (5), steam inlet pipe (6), drain pipe (7), micropore (8), vent (9).
Below in conjunction with accompanying drawing in detail the utility model embodiment is described in detail:
Novel as shown in drawings multitube steam, air emptying silencing apparatus are made of base (1), shell (2), multi-step pressure reduction pipe (3) three parts, the main cylindrical body of looking into.Base (1) garden shape, there is steam inlet pipe (6) at its center, the drain pipe that kept to the side (7).Shell (2) is a upper shed garden cylindrical shell, and barrel is a sandwich structure, and by outer sleeve (4) and microwell plate (5) top edge seam, lower limb is welded in and forms interlayer on the base, and microwell plate (5) is evenly distributed with micropore (8), aperture 1-4MM.In cylindrical shell center, shell garden multi-step pressure reduction pipe (3) is set, manages concentric suit by 1-10 garden and constitute, sealing suitable for reading is managed in each garden, and lower limb is welded on the base, and each even tube wall is distributed with vent (9), aperture 2-20MM.In the working procedure, steam, air enter silencing apparatus by steam inlet pipe (6), after one-level relief pipe expansion decompression, expand through second level relief pipe and reduce pressure, so by multi-step pressure reduction pipe decompression noise elimination back emptying.The cooling water that forms is leaked by drain pipe (7).Because of the reason that produces noise mainly is to produce due to the seismic wave at exhaust port under certain pressure, flow velocity because of steam, air, by the multi-step pressure reduction pipe, vapor pressure, flow velocity are decayed rapidly, be that seismic source energy decays rapidly, the sound wave that is caused is decayed rapidly, reaching the noise elimination purpose, is the principal element of eliminating noise so eliminate the noise by the decompression of multi-step pressure reduction pipe.Take second place, steam, air and caused seismic wave thereof produce attenuation processes such as reflection, phase cancellation between each relief pipe tube wall, make steam, air energy and cause that the energy of seismic wave decays rapidly, be another factor of elimination noise.Again, the interlayer shell (2) of band microwell plate, its effect is equivalent to acoustic board, and steam, air by multi-step pressure reduction is eliminated the noise run into microwell plate interlayer shell and will produce damping, sound-absorbing noise elimination effect, and this is the another factor that emptying is eliminated the noise.Owing to the acting in conjunction of above-mentioned multi-step pressure reduction pipe and microwell plate interlayer shell, reach the purpose of emptying noise elimination.Microwell plate (5) environment of living in is more abominable, and for preventing to stop up, influence sound-absorbing noise elimination effect and reduction of service life because of corrosion causes micropore, so adopt corrosion resistant plate to make, also available certainly general steel plate is made, and just using effect and life-span are relatively poor.Other parts of the present utility model are all made with general steel plate.
The Environmental Conditions complexity of silencing apparatus reality, changeable, during the development and Design product, should determine multi-step pressure reduction pipe progression, each relief pipe caliber, vent aperture, distribution density according to noise elimination technique index, steam or air pressure, flow, specific volume, temperature factors; Determine microwell plate micropore size, distribution density; Determine each several part physical dimension etc.Succeed in developing at present ZX series and be suitable for steam, the air emptying silencing apparatus that boiler, steam turbine, steam generator, steam pipe system and pneumatics facility are used.
Embodiment one, novel multitube steam, air emptying silencing apparatus, interlayer shell (2) and second depressurized pipe (3) by base (1), band microwell plate (5) constitute, outer sleeve (4) and microwell plate (5) top edge seam, lower limb is welded on the base, constitute interlayer shell (2), outer sleeve (4) diameter 360MM; Microwell plate (5) diameter 280MM, micropore (8) evenly distributes, aperture 1MM, totally 13000; One-level relief pipe diameter 60MM, vent (9) evenly distributes, aperture 5MM, totally 60; Second depressurized pipe diameter 160MM, vent (9) evenly distributes, aperture 4MM, totally 240; Steam inlet pipe (6) diameter 55MM, drain pipe diameter 25MM; Except that microwell plate (5) was made by corrosion resistant plate, all the other were made by general steel plate.Present embodiment, the working environment that is suitable for 150 ℃ of steam flow 2t/h, vapor pressure 0.3MPa, temperature uses, practical effect, apart from silencing apparatus 2M, noise is lower than 90 decibels.
Embodiment two, and novel multitube steam, air emptying silencing apparatus are made of the Pyatyi relief pipe, and all the other structural forms are identical with embodiment one, and main design parameters is: outer sleeve (4) diameter 900MM; Microwell plate (5) diameter 800MM, micropore evenly distributes, aperture 1.5MM, totally 150000; One-level relief pipe diameter 140MM, vent (9) evenly distributes, aperture 15MM, totally 40; Second depressurized pipe diameter 200MM, aperture 10MM, totally 70; Three grades of relief pipe diameter 300MM, aperture 10MM, totally 100; Level Four relief pipe diameter 400MM, aperture 6MM, totally 250; Pyatyi relief pipe diameter 500MM, aperture 4MM, totally 4000.Microwell plate (5) is made for corrosion resistant plate.Present embodiment, working environment are steam flow 40t/h, pressure 3.8MPa, 450 ℃ of temperature.Using effect is apart from silencing apparatus 2M, and noise is lower than 90 decibels.
