Abstract

The utility model relates to an improved pressure swing adsorption nitrogen making machine silencer which comprises an outer cylinder, an air inlet pipe section, silencing materials and a back cover plate. The air inlet pipe section stretches into the outer cylinder, a pipe end of the air inlet pipe section, stretching into the outer cylinder, is provided with a seal cover, a columnar face of the pipe section is provided with a plurality of holes, a plurality of exhaust small holes are formed in the thickness direction of the back cover plate in a concentrated mode, the back cover plate is fixed to a screw led out from the seal cover of the pipe end of the air inlet pipe section through a nut, and the silencing materials are filled in a space defined by the outer wall stretching into an outer cylinder inner pipe section, the inner wall of the outer cylinder and the back cover plate in an enclosing mode. The improved pressure swing adsorption nitrogen making machine silencer has the advantages that the void content of the silencer is far larger than that of a common nitrogen making machine silencer, and the silencing materials are also installed inside the silencer to enable the silencing effect to be more significant than that of a common silencer. In addition, inside space and the exhaust aperture of the improved pressure swing adsorption nitrogen making machine silencer are larger than those of the common silencer, and therefore the exhaust effect is better than that of the common silencer.

Description

Improved type varying-voltage adsorption nitrogen machine baffler
Technical field
The utility model relates to a kind of baffler of gas fractionation unit, especially relates to a kind of improved type varying-voltage adsorption nitrogen machine baffler.
Background technique
In the prior art, PSA Gas Separation Technology has that energy consumption is low, easy to operate, the good plurality of advantages of environmental benefit, adopts the Double-Tower Structure gas separation equipment of this technology to be widely used.For example, nitrogen generator, oxygenerator.Because this class machine is by two separator alternations, the time of exhaust is short and amount is also large, therefore the noise that produces is also large.Common emptying silencer is to adopt several small silencers to be connected on the gas system evacuation pipeline processed, the actual effect of this small-sized silencing apparatus is also not obvious, using some bafflers of the same type at some large-scale nitrogen generator, because the flow of exhausting air is large, the actual erasure effect of baffler is also bad, and the noise that produces during discharging can be very large.Therefore for the consideration of client to the noise reduction discharging, the inventor carries out improvement design in conjunction with on-the-spot characteristics for the structure of nitrogen generator baffler emptier.
Summary of the invention
The purpose of this utility model is to provide a kind of for the prior art deficiency can stablize the effectively improved type varying-voltage adsorption nitrogen machine baffler of noise-decreasing of waste air.
The purpose of this utility model is to realize by following measures: a kind of improved type varying-voltage adsorption nitrogen machine baffler, and it comprises urceolus, air inlet pipeline section, it is characterized in that, also has quieter material, back shroud; Described air inlet pipeline section stretches in the urceolus, stretch into the cylinder that the pipe end of air inlet pipeline section in the urceolus is provided with capping, pipeline section and offer some holes, described back shroud thickness of slab direction is intensive to offer some exhaust holes, back shroud is fixed on the screw rod of being drawn by air inlet pipeline section closure plug by nut, and stretching into the space-filling that outer wall, outer tube inner wall, the back shroud of pipeline section surrounds in the urceolus has quieter material.
Described quieter material is steel wire lump or steel wire or coconut palm pad.
Compared with prior art, adopted the improved type varying-voltage adsorption nitrogen machine baffler that the utility model proposes, have following advantage: the porosity ratio of the utility model baffler will be far longer than the baffler of general nitrogen generator, and inside also is equipped with quieter material, so that soundproof effect is much more obvious than the effect of general baffler.In addition, noise reduction of the present utility model inner space and discharging bore are more much bigger than general baffler, so emission effect is also effective than general baffler.
Description of drawings:
Fig. 1 is an example structure schematic diagram that the utility model proposes.
Embodiment:
Below in conjunction with accompanying drawing embodiment is elaborated: in an embodiment of the present utility model shown in Figure 1.Among the figure, a kind of improved type varying-voltage adsorption nitrogen machine baffler, it comprises: urceolus 2, air inlet pipeline section 1, quieter material 4, back shroud 3; Described air inlet pipeline section 1 stretches in the urceolus 2, the pipe end that stretches into urceolus 2 interior air inlet pipeline sections is provided with capping, the pipeline section cylinder offers some holes, described back shroud 3 thickness of slab directions are intensive to offer some apertures, back shroud 3 is fixed on the screw rod of being drawn by air inlet pipeline section 1 closure plug by nut, stretching into the space-filling that outer wall, urceolus 2 inwalls, the back shroud 3 of urceolus 2 interior air inlet pipeline sections 1 surround has quieter material 4, and described quieter material is steel wire lump or steel wire or coconut palm pad.
Show through practice, pinhole type silencing apparatus of the present utility model has Low Medium Frequency broadband acoustic attenuation performance, acoustic absorptivity can be improved in little aperture, low porosity ratio can increase the width of sound sucting band, the in addition quieter material in the urceolus, can make substantially the emptying reducing noise of nitrogen generator, reach the industrial noise emission standard.
The embodiment that the above provides does not consist of restriction of the present utility model, and those skilled in the art make within the scope of the appended claims various distortion or revise all in protection domain in related domain.

Claims (2)
