Abstract
The utility model relates to a device of PSA air separation equipment, more particularly to a silencer that reduces noises from a piece of pressure swing absorption type oxygen and nitrogen making equipment. The silencer comprises an external cylinder, a heat keeping plate in the external cylinder, and a noise silencing and filtering screen. Between the heat keeping plate and the noise silencing and filtering screen is provided a filling layer. The external cylinder is formed by the connection of an upper sealing plate and a lower sealing plate. The upper sealing plate and the lower sealing plate are detachable end plates. As the upper sealing plate and the lower sealing plate can be detached conveniently, the noise silencing materials in the filling layer can also be conveniently changed and the inner wall of the silencer can be conveniently washed as well. The filling layer and the noise silencing and filtering screen divide the inner part of the silencer to a reverted T structure in the silencer, which makes air flows hedge mutually with the result of offsetting sound waves. Therefore, the noise silencing performance further improves. Further, a sample taking mouth is arranged at the upper part of the silencer inlet, which can monitor exhausted air at real time, and provide air purity samples to ensure the equipment to function in a normal state.
Description
Technical field
The utility model relates to PSA gas space subset, particularly a kind of sound suppressor that reduces omnibus control system equipment of making nitrogen noise.
Background technology
Old-fashioned PSA gas space subset sound suppressor urceolus and noise elimination filter net are entirely to weld integral type, once stop up, clean very difficult.At present comparatively advanced PSA gas space subset sound suppressor on the market, if the patent No. is the disclosed a kind of oxygen equipment of making nitrogen sound suppressor of ZL200720303035.8, urceolus and wire gauze are bolted to connection, can disassembly, cleaning, and be provided with buffering warming plate, but simple warming plate still cannot thoroughly solve the problem of the huge noise of sound wave vibrations generation, and this sound suppressor to also have a defect be exactly that any exhaust sampling device is not set, timely monitoring cannot be accomplished to tail gas, gas purity can not be ensured.
Utility model content
The purpose of this utility model is to provide a kind of PSA gas space subset sound suppressor that can reduce sonic impinging vibrating noise and tail gas monitoring is provided, the huge vibrations and the noise that cause to solve prior art sonic impinging silencer internal wall, and cannot accomplish that monitoring in time provides the problem of purity to tail gas.
Above-mentioned technical matters of the present utility model is solved by following technical proposals: the utility model comprises urceolus, urceolus inside is provided with buffering warming plate, noise elimination filter net, described urceolus and upper sealing plate, lower shrouding are formed by connecting, and described upper sealing plate, lower shrouding are detachable end plate.In the middle of described warming plate and noise elimination filter net, be provided with packed layer.
As preferably, described upper sealing plate, lower shrouding are fixedly connected with by nut bolt with described urceolus, and convenient disassembly cleans easily.
As preferably, described outer tube inner wall is equipped with buffering warming plate, and described warming plate is connected with upper sealing plate, the upper and lower two ends of lower shrouding, guarantees sound suppressor key property.
As preferably, in the middle of described warming plate and described noise elimination filter net, be provided with packed layer, packing material is noise elimination cotton or glass fiber, reduces sound wave and silencer internal wall is impacted to the huge vibrations and the noise that cause.
As preferably, described packed layer becomes down " T " font structure with noise elimination filter net by sound suppressor interior separation, and air-flow is liquidated inner formation of sound suppressor, sound wave is caused and cancel out each other, and further improves acoustic attenuation performance.
As preferably, described noise elimination filter net is woven wire or other wire gauzes.
Do preferably, described lower shrouding is provided with import, and described upper sealing plate is provided with drain, and described import top is provided with sample tap, monitors in time tail gas, and gas purity sample is provided, and ensures the operation of PSA gas space subset high-level efficiency high-quality.
The beneficial effects of the utility model are: upper sealing plate, lower shrouding and noise elimination filter net are all detachable, convenient cleaning.Between warming plate and noise elimination filter net, increase packed layer, packed layer is filled deadener naturally, and deadener both conveniently exchanged for, has reduced again sound wave and silencer internal wall has been impacted to the huge vibrations and the noise that produce, improves acoustic attenuation performance.Packed layer becomes down " T " font structure with noise elimination filter net by sound suppressor interior separation, and air-flow is liquidated inner formation of sound suppressor, sound wave is caused and cancel out each other.Muffler inlet top is provided with sample tap, can, at any time to tail gas monitoring, provide gas purity sample, and guarantee equipment moves normally and efficiently.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the present utility model
In figure: 1. descend shrouding, 2. bolt, 3. warming plate, 4. packed layer, 5. urceolus, 6. noise elimination filter net, 7. upper sealing plate, 8. import, 9. drain, 10. sample tap.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: a kind of PSA gas apparatus sound suppressor of the present embodiment, as shown in Figure 1, comprise urceolus 5, urceolus 5 is fixedly connected with upper sealing plate 7, lower shrouding 1 by bolt 2, upper sealing plate 7, lower shrouding 1 are detachable end plate, urceolus 5 inwall assembling warming plates 3, warming plate 3 two ends connect upper sealing plate 7, lower shrouding 1, urceolus 5 inside are provided with noise elimination filter net 6, warming plate 3 arranges packed layer 4 with noise elimination filter net 6 is middle, and packing material is noise elimination cotton or glass fiber, and lower shrouding 1 one sides are import 8, upper sealing plate 7 one sides are drain 9, and import 8 tops arrange sample tap 10.
The utility model is that nut bolt is assembled into, and upper sealing plate, lower shrouding, noise elimination filter net and packed layer are all detachable plates, conveniently clean and renew.Old-fashioned sound suppressor is not filled, and is provided with blowdown interface in lower shrouding position, and blowdown interface is also very little, and due to upper sealing plate, lower shrouding convenient disassembly, blowdown interface performs practically no function again.The utility model is cancelled blowdown interface, is provided with on the basis of warming plate keeping, and in the middle of noise elimination filter net and warming plate, increases packed layer, fill deadener exchange for very easy, prolongation sound suppressor serviceable life.Deadener is noise elimination cotton or glass fiber, and deadener thickness is not less than 70mm.Can reduce to greatest extent PSA gas apparatus noise.Packed layer becomes down " T " font structure with noise elimination filter net by sound suppressor interior separation, and air-flow is liquidated inner formation of sound suppressor, sound wave is caused and cancel out each other, and extends noise and spreads out of the time, reduces the decibel that noise spreads out of, and further improves Muffler Performance.Muffler inlet top is provided with sample tap, monitors at any time tail gas, extracts tail gas sample, ensures gas purity, ensures the operation of PSA gas space subset high-level efficiency high-quality.
