The silencer has the advantages that the hole plate is fixed by the air outlet end of the silencer outer shell through the fastener, the coconut mat is arranged between the silencer outer shell and the hole plate, silencing effect of the silencer is better, noise of pressure swing adsorption gas fractionation device is reduced, physical and psychological health of an operator is ensured, the porcelain ball is arranged inside the silencer outer shell, replacement is convenient and operation is simple.
Description
Technical field
The utility model relates to a kind of silencing apparatus, especially relates to the emptying silencing apparatus of a kind of pressure varying adsorption gas separating equipment.
Background technique
Pressure swing adsorption air separation plant is to adopt molecular sieve as sorbent, utilizes the principle of pressure-variable adsorption to obtain the equipment of single gas or mixed gas.Under certain pressure, utilize various gases in the mixed gas in the difference of molecular sieve surface sorption amount, by the keying of programmable control pneumatic valve, reach two towers or multitower alternate cycles, the process of pressurization absorption, decompression desorption is finished oxygen nitrogen and is separated, thereby obtains the nitrogen of required purity.When adsorber can produce very strong noise during by emptying, had a strong impact on operator's physical and mental health.
Nowadays, most acoustic wave filter structure is complicated, and it is comparatively loaded down with trivial details that muffler material is changed operation, and soundproof effect is relatively poor.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of simple in structure, easy to operate, obvious silencing apparatus of soundproof effect.
A kind of silencing apparatus comprises adpting flange, outlet pipe, porcelain ball, guard, muffler shell, coconut palm pad and orifice plate, outlet pipe one end is connected with flange, outlet pipe is provided with aperture, exhaust shroud is connected in the muffler shell and an end of this outlet pipe adpting flange is in the muffler shell outside, be provided with guard between outlet pipe and the muffler shell, the porcelain ball is housed in the muffler shell, and the outlet side of described muffler shell is provided with the coconut palm pad by the fixing orifice plate of fastening piece between muffler shell and the orifice plate.
Preferably, described guard is comprised of 3 layers of Stainless Steel Cloth.
Preferably, described Stainless Steel Cloth is 40 orders.
Preferably, the aperture of aperture is 3mm-5mm on the described outlet pipe.
Preferably, described outlet pipe is comprised of a seamless steel pipe
Beneficial effect of the present invention is: the outlet side of muffler shell is by the fixing orifice plate of fastening piece, be provided with the coconut palm pad between muffler shell and the orifice plate, make the erasure effect of baffler better, reduce the noise of pressure swing adsorption gas separation device, ensured operator's physical and mental health; The porcelain ball is housed in the muffler shell, and it is convenient, simple to operate to change.
Description of drawings
Fig. 1 is overall structure schematic representation of the present utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing structure of the present invention is described further.
As shown in Figure 1, a kind of silencing apparatus comprises adpting flange 1, outlet pipe 2, porcelain ball 3, guard 4, muffler shell 5, coconut palm pad 6 and orifice plate 7, outlet pipe 2 one ends are connected with flange 1, outlet pipe 2 is provided with aperture, outlet pipe 2 is socketed in the muffler shell 5 and an end of these outlet pipe 2 adpting flanges 1 is in muffler shell 5 outsides, be provided with guard 4 between outlet pipe 2 and the muffler shell 5, porcelain ball 3 is housed in the muffler shell 5, the outlet side of described muffler shell 5 is by the fixing orifice plate 7 of fastening piece, be provided with coconut palm pad 6 between muffler shell 5 and the orifice plate 7, guard 4 is comprised of 3 layers of Stainless Steel Cloth, Stainless Steel Cloth is 40 orders, the aperture of aperture is 3mm-5mm on the outlet pipe 2, outlet pipe is comprised of a seamless steel pipe, be drilled with the numerous aperture that is evenly distributed on the seamless steel pipe, with clip several layers of 40 purpose stainless steel steel wire are encased periphery at seamless steel pipe, the seamless steel pipe inlet end is fixedly connected with flange, be used for connecting the pressure varying adsorption gas separating equipment evacuation port, assemble always hush pipe at outlet pipe, the porcelain ball of in-built granular shape.Push down the porcelain ball with the coconut palm pad, use again orifice plate is fixed on the hush pipe, prevent the porcelain ball efflorescence that makes because of the huge impact force of emptying generation.
The silencer of this patent adopts spray dissipative type and the resistive principle that combines, spray dissipative muffler.Because crest frequency and the nozzle diameter of jet noise are inversely proportional to, although reduce the aperture high frequency sound are increased, people's ear is not heard, and people's ear institute can reduce by audible all-bottom sound.Small-Bore Jet Noise Muffler adopts this principle exactly, uses a spout spray instead many enough little micropore jets, makes noise energy shift to the insensitive high-frequency range of people's ear from low frequency, thereby interference noise is reduced, but air displacement remains unchanged.
Dissipative muffler also claims that absorbing silencer is the sound absorption of utilizing sound-absorbing material, make along the noise of channels spread constantly be absorbed and gradually the decay device.Sound-absorbing material is fixed on the pipeline perisporium that air-flow passes through, or lines up in passage by certain way, just consist of dissipative muffler.Its noise-cancelling theory is: when sound wave enters silencing apparatus, just cause aluminium oxide or porcelain ball in the porous material in the dissipative muffler, because surface friction drag and viscous resistance, make a part of acoustic energy be converted into heat energy and lose, play the noise elimination effect.
At last, should be pointed out that above embodiment only is the more representational example of the present invention.Obviously, the invention is not restricted to above-described embodiment, many distortion can also be arranged.Every foundation technical spirit of the present invention all should be thought to belong to protection scope of the present invention to any simple modification, equivalent variations and modification that above embodiment does.
