Description
Technical field
The present invention relates to the technical field of reduction natural gas compressor exhaust noise, particularly a kind of natural gas compressor row
Gas silencing means.
Background technology
Natural gas compressor muffler be it is a kind of permission air-flow by and the device of noise attenuation, be natural gas compressing
One of important spare part on machine.The quality of Muffler Performance not only influences the size harmony ring of natural gas compressor exhaust noise
The pollution in border, and the performance such as the power to engine, gas consumption, moment of torsion has considerable influence.
Natural gas compressor exhaust noise is as the pneumatic noise produced by compressor power cylinder burning and exhausting tail gas.Through dynamic
Power cylinder exhaust noise spectrum measurement is analyzed, when engine is run, and exhaust ports produce larger noise, and through on-the-spot test, it is made an uproar
Sound value is up to 103dB（A）, it is maximum especially in blast pipe stage casing noise figure, noise frequency is in, based on low-frequency noise, noise
Frequency values are 20Hz, and the heart rate of human body is also 20Hz, and both produce covibration, and amplitude becomes big during resonance, to personal around
Body causes great harm, while bringing pollution to surrounding enviroment, therefore is badly in need of reduction noise frequency.
The content of the invention
It is an object of the invention to overcome the shortcoming of prior art there is provided a kind of compact conformation, effectively reduce noise on human
Body injury, effectively reduction Noise upon Environment pollute, assemble easy natural gas compressor exhaust muffling device.
The purpose of the present invention is achieved through the following technical solutions：A kind of natural gas compressor exhaust muffling device, it is wrapped
Include noise reduction tower and bellows, in described noise reduction tower and be provided with from top to bottom on multiple dividing plates, each dividing plate be provided with it is perpendicular
Pipe, the vertical tube on adjacent two dividing plate is staggered setting, and the upper end of vertical tube offers multiple exhaust holes, described noise reduction tower
Top is provided with floss hole, and the bottom of noise reduction tower, which is provided with air inlet, air inlet, is connected with bellows, bellows it is another
End, which is connected with straight tube, straight tube inwall, is laid with heat insulation foam layer, and the other end of straight tube is connected with joint.
Described noise reduction tower, bellows, straight tube and joint is sequentially arranged by from left to right.
Described noise reduction tower is post shapes.
Described exhaust hole is evenly distributed on vertical tube.
Three dividing plates are provided with described noise reduction tower, three dividing plates are arranged in parallel.
Mounting hole is offered on described dividing plate.
Described vertical tube is plugged in mounting hole.
The present invention has advantages below：Compact conformation of the present invention, effectively reduction noise on human body injure, effectively reduce noise
Environmental pollution, assembling are easy.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is the structural representation of vertical tube；
In figure, 1- noise reduction towers, 2- bellowss, 3- dividing plates, 4- vertical tubes, 5- exhaust holes, 6- floss holes, 7- air inlets, 8- straight tubes,
9- joints, 10- mounting holes, 11- heat insulation foams layer.
Embodiment
The present invention will be further described below in conjunction with the accompanying drawings, and protection scope of the present invention is not limited to as described below：
As shown in Figure 1 and 2, a kind of natural gas compressor exhaust muffling device, it include noise reduction tower 1 and bellows 2, noise reduction tower 1,
Bellows 2, straight tube 8 and joint 9 are sequentially arranged by from left to right, described noise reduction tower 1 be in post shapes, noise reduction tower 1 and on toward
It is arranged with multiple dividing plates 3, the present embodiment, three dividing plates 3 is provided with noise reduction tower 1, three dividing plates 3 is arranged in parallel,
The vertical tube 4 being provided with each dividing plate 3 on vertical tube 4, adjacent two dividing plate 3 is staggered setting, and the upper end of vertical tube 4 offers many
Individual exhaust hole 5, exhaust hole 5 is evenly distributed on vertical tube 4.The top of described noise reduction tower 1 is provided with floss hole 6, noise reduction
The bottom of tower 1, which is provided with air inlet 7, air inlet 7, is connected with bellows 2, and the other end of bellows 2 is connected with straight tube 8, directly
Heat insulation foam layer 11 is laid with the inwall of pipe 8, the other end of straight tube 8 is connected with joint 9, and joint 9 is used to fire with compressor power cylinder
Burn the connection of emission pipe.
Mounting hole 10 is offered on described dividing plate 3；Described vertical tube 4 is plugged in mounting hole 10.
The course of work of the present invention is as follows：Compressor power cylinder burning and exhausting offgas duct is connected with joint 9, by compressing
The tail gas of mechanomotive force cylinder burning and exhausting enters in straight tube 8 through joint 9, after heat insulation foam layer 11 is contacted with high-temperature tail gas, heat insulation foam layer
11 occur heat exchange with high-temperature tail gas, it is to avoid heat increases surrounding working environment temperature after being discharged with tail gas, while being also avoided that
Straight tube surface temperature is too high and damages；Under gas pressure, tail gas enters bellows 2, and bellows 2 slows down tail gas flow velocity, simultaneously
Tail gas is set impact effect occur in the inwall of bellows 2, to realize preliminary reduction noise；Under gas pressure, tail gas is through air inlet 7
Region between noise reduction tower 1 and bottom dividing plate 3, is then moved from lower to upper again, and tail gas enters on orlop dividing plate 3
In vertical tube 4, moved along exhaust hole 5 towards the wall of noise reduction tower 1, the vertical tube 4 on each layer dividing plate 3 is then gradually passed through, in this process
There is continuous impact effect with the wall of noise reduction tower 1 in middle tail gas, and tail gas flow velocity further slows down, finally discharged from floss hole 6.Therefore originally
Device is 10 ~ 12Hz by bellows 2 and the two-stage noise reduction of noise reduction tower 1, after measured exhaust gas flow noise frequency, and noise is in 45dB
Within, covibration will not occur with human heart rate, the injury of noise on human body be effectively reduced, while effectively reducing noise pair
Environmental pollution.
