Abstract
The invention discloses a silencer used for an adsorption type drier, comprising a cylindrical body and 10-20 plate bodies. An inner cylindrical body and an outer cylindrical body sleeving the inner cylindrical body are arranged inside the cylindrical body; the inner cylindrical body is internally provided with plate bodies; each plate body is provided with a plurality of ventilation holes; the ventilation holes on the adjacent plate body are arranged in a staggering manner; a sound insulation material is positioned between the inner cylindrical body and the outer cylindrical body; the inner cylindrical body comprises a first inner cylindrical body and a second inner cylindrical body which are arranged from the up to the bottom; the plate bodies are arranged inside the second inner cylindrical body; the inner side of the first inner cylindrical body are provided with a plurality of through holes which are coated with a silencing material layer. In the invention, the ventilation holes on the adjacent plate body are arranged in a staggering manner. When the compressed air goes inside the inner cylindrical body of the silencer, the flow speed of the compressed air in the silencer can be reduced. On the other hand, the through holes are arranged on the inner cylindrical body and a layer of glass cloth is wrapped on the multi-hole inner cylindrical body. With that structure, the multi-hole inner cylindrical body can reduce the flow speed of the compressed air inside the silencer, and the noise reduction can be achieved.
Description
Technical field
The present invention relates to the mechanism in energy-conserving and environment-protective field, particularly the sound suppressor of absorption type dryer in Bihend Processing Equipment of Compressed Air.
Background technology
General absorption type dryer adopts two drying towers substantially, and a tower drying agent adsorbs the moisture content in pressurized air, and another tower is that finished product gas (or hot-air) carries out desorption and regeneration to the moisture content in drying agent; When absorption and desorption complete, two drying towers need to switch, switching in a flash, the high pressure air in desorption column can in several seconds in discharged by sound suppressor; If the treatment capacity of exsiccator large (namely the volume of drying tower is large), the air supply of discharging in desorption column is relatively also large, and at this moment, the noise of discharging pressurized air generation is also very large, causes noise pollution to the environment of surrounding.
The sound suppressor that present producer adopts is generally adopt the multilayer board of through hole to be contained in an inner barrel, between inner barrel and outer cylinder body, glaze is cotton, straight-through between the multilayer plate hole of through hole and hole inside this type of sound suppressor, pressurized air does not slow down flow velocity through buffering through sound suppressor, although be equipped with glass wool between inner barrel and outer cylinder body, the noise that when high pressure, large discharge, pressurized air produces is very large.
Summary of the invention
The object of the present invention is to provide and a kind ofly slow down the flow velocity of pressurized air in sound suppressor, reach reduce noise object for the sound suppressor of absorption type dryer.
To achieve these goals, present invention employs following technical scheme:
A kind of sound suppressor for absorption type dryer, comprise cylindrical shell and 10 ~ 20 plate bodys, the head end of described cylindrical shell is provided with air intake opening, end is provided with exhausr port, described cylindrical shell comprises inner barrel and is set in the outer cylinder body of described inner barrel outside, be provided with the described plate body that some and described air intake opening be arranged in parallel in described inner barrel, each described plate body is provided with multiple air hole, and the air hole of adjacent two plate bodys staggers setting.
Further, described plate body is connected by coupling shaft, and one end of this coupling shaft is fixed on described cylindrical shell.
Further, sound-proof material is provided with between described inner barrel and outer cylinder body.
Preferably, this sound-proof material is the good super glass wool of sound-absorbing effect, super glass wool is for primary raw material with silica sand, feldspar, sodium silicate, boric acid etc., the fiber cotton like being less than 2um is obtained through high temperature melting, add the sizing of thermosetting resin bonding agent pressurized high-temperature again and produce various shape, the plate of specification, felt, tubing article, there is the superior functions such as unit weight is light, coefficient of heat conductivity is little, absorption coefficient is large, fire resistance is good.
As another kind of technical scheme, described inner barrel comprises the first inner barrel and the second inner barrel that set gradually from top to bottom, and described plate body is arranged in described second inner barrel.
Preferably, the sidewall of described first inner barrel is provided with multiple through hole, and described first inner barrel is coated with quieter material layer, and this quieter material is placed between described sound-proof material and described first inner barrel.
Preferably, described quieter material layer is glass cloth.
The present invention is by arranging inner barrel and outer cylinder body, decrease the diffusion of sound, simultaneously, stagger between air hole between adjacent plate body, after pressurized air enters sound suppressor inner barrel, the effect slowing down the flow velocity of pressurized air in sound suppressor can be reached, the present invention can arrange through hole in inner barrel in addition, form porous inner cylinder body, simultaneously at porous inner cylinder external parcel one deck glass cloth, the benefit of this spline structure is that porous inner cylinder body also can slow down the flow velocity of pressurized air in sound suppressor, reaches the object reducing noise.
