Description
Technical field
The present invention relates to the mechanisms of energy conservation and environmental protection, in particular to absorption type dryer in Bihend Processing Equipment of Compressed Air
Silencer.
Background technique
General absorption type dryer substantially uses two drying towers, a tower desiccant to the moisture content in compressed air into
Row absorption, another tower are that finished product gas (or hot-air) carries out desorption and regeneration to the moisture content in desiccant；When adsorbing and be desorbed
At two drying tower needs switch over, and in a flash, the high pressure air in desorption column interior in several seconds can pass through for switching
Silencer discharges；If the treating capacity of drier is big (volume of namely drying tower is big), the compression being discharged in desorption column
Air capacity is relatively also big, and at this moment, the noise that discharge compressed air generates is also very big, causes noise pollution to the environment of surrounding.
The multi-layer board of through-hole is usually used in an inner cylinder in the silencer that present producer uses, inner cylinder and outer
Glaze cotton between cylinder, between the multilayer plate hole and hole of through-hole be inside such silencer it is straight-through, compressed air is by disappearing
Buffering is not passed through when sound device to slow down flow velocity, although mineral wool is equipped between inner cylinder and outer barrel, when high pressure, big flow
The noise that compressed air generates is very big.
Summary of the invention
The purpose of the present invention is to provide a kind of flow velocity for slowing down compressed air in silencer, reach the mesh for reducing noise
The silencer for absorption type dryer.
To achieve the goals above, present invention employs the following technical solutions:
A kind of silencer for absorption type dryer, including cylinder and 10 ~ 20 plate bodys, the head end of the cylinder are set
There is an air inlet, end is equipped with exhaust outlet, and the cylinder includes inner cylinder and the outer barrel that is set in outside the inner cylinder, institute
It states and is equipped with several and air inlet plate body disposed in parallel in inner cylinder, each plate body is equipped with multiple ventilations
The venthole in hole, two neighboring plate body is arranged in a staggered manner.
Further, by connection axis connection, one end of the connecting shaft is fixed on the cylinder plate body.
Further, acoustic material is equipped between the inner cylinder and outer barrel.
Preferably, which is the preferable super glass wool of sound-absorbing effect, and super glass wool is with quartz sand, length
Stone, sodium metasilicate, boric acid etc. are primary raw material, the fiber cotton like of 2um are made smaller than by high temperature melting, then add heat curing type
The sizing of resin binder pressurized high-temperature produces various shape, the plate of specification, felt, tubing article, the light, thermal coefficient with bulk density
The small, superior functions such as absorption coefficient is big, flame retardant property is good.
As another technical solution, the inner cylinder includes the first inner cylinder and second from top to bottom set gradually
Inner cylinder, the plate body are arranged in second inner cylinder.
Preferably, the side wall of first inner cylinder is equipped with multiple through-holes, and first inner cylinder is coated with noise reduction
Material layer, the quieter material are placed between the acoustic material and first inner cylinder.
Preferably, the quieter material layer is glass cloth.
The present invention reduces the diffusion of sound by setting inner cylinder and outer barrel, meanwhile, it is logical between adjacent plate body
It is staggered between stomata, after compressed air enters silencer inner cylinder, can achieve the stream for slowing down compressed air in silencer
The effect of speed, in addition through-hole can be arranged in the present invention in inner cylinder, form porous inner cylinder body, while wrapping in vitro in porous inner cylinder
One layer of glass cloth is wrapped up in, the benefit of this spline structure is that porous inner cylinder body can also slow down flow velocity of the compressed air in silencer, is reached
To the purpose for reducing noise.
