Technical field
The present invention relates to a kind of silencing apparatus, specifically a kind of blower export pipe type silencing apparatus.
Background technique
Blower is the common equipment that air compressing is carried, and is widely used in all trades and professions such as industrial production and municipal wastewater processing.Blower in use; in fan outlet and follow-up pipeline, can produce larger noise, in order to reduce noise, conventionally can on the outlet conduit of blower, muffling device be installed; silencing apparatus is a kind of device that stops sound transmission and allow air-flow to pass through, and can weaken the noise that blower fan produces.The soundproof effect of existing blower silencing apparatus is undesirable, and the level of noise after noise reduction is still difficult to meet the requirement of noise pollution control standard, easily operator's the sense of hearing is damaged and surrounding enviroment are made a very bad impression.
Summary of the invention
The object of the present invention is to provide a kind of blower export pipe type silencing apparatus, overcome the undesirable problem of existing blower silencing apparatus soundproof effect, provide a kind of good muffling effect, the silencing equipment that level of noise is low.
The object of the invention is to realize in the following manner, its structure is by screen casing in the diffusion of close hole, close hole diffusion outer screen pipe, outer air guide sound insulation tube and close hole dividing plate form, wherein, in the diffusion of close hole, one end portion of screen casing and close hole diffusion outer screen pipe is respectively arranged with flange, in the diffusion of close hole, the right-hand member of screen casing is by the close hole sizer plate of hemisphere shutoff cecutiency tubulose, close hole dividing plate is arranged among the interior screen casing of close hole diffusion, close hole diffusion outer screen pipe is through, in the left end opening of close hole diffusion outer screen pipe spreads with close hole together with the flange welding of screen casing, the two ends of outer air guide sound insulation tube are spread on the two ends cylindrical of outer screen pipe by arc joint weld in close hole, be provided with one end of the close hole sizer plate of hemisphere, from the non-flanged one end of outer air guide sound insulation tube, inject, by the supporting rib being arranged on close hole diffusion outer screen pipe inwall, be connected with direction recess on screen casing outer wall in the diffusion of close hole, in close hole is spread, screen casing is fixed among close hole diffusion outer screen pipe, in the left end opening of close hole diffusion outer screen pipe and the diffusion of close hole, screen casing welds together, one end that diffusion interior screen casing left end in close hole is provided with flange is flue gas inlet end, one end that close hole diffusion outer screen pipe right-hand member is provided with flange is smoke outlet.
A kind of blower export pipe type silencing apparatus of the present invention is compared outstanding feature with existing blower muffler device and is:
(1) internal layer courage formula porous air diffuser is set, plays the effect that many diffusions are eliminated the noise;
(2) close hole diffusion outer screen pipe is placed in internal layer courage formula porous air diffuser radial outer periphery, two interlayers leave rational wall, air-flow produces resistance damping and plays noise elimination effect after internal layer eyelet enters wall, rule due to internal layer eyelet distributes simultaneously, air flow stream makes again original noise producing interference, diffraction at wall later, plays soundproof effect;
(3) outer air guide sound insulation tube is placed in close hole diffusion outer screen pipe radial outer periphery, the diameter length that install pipeline is enough, and airflow passes sieve plate enters in peripheral conduits, plays again the effect that many diffusions are eliminated the noise;
(4) acoustic wave filter structure is simple, simple for production.
