Description
Technical field
The utility model relates to a kind of improvement of condenser/evaporator support construction, refer in particular to a kind of low suitable for -20 DEG C or less
The condenser/evaporator support construction of the damping noise reduction of temperature.
Background technique
The noise abatement of air separation unit is in industry also emphasis with the reinforcement of national environmental protection consciousness and environment protection treating
Research topic.The noise abatement means and method of dynamic equipment have reached its maturity, but then for the noise abatement of static equipment
It is one piece of blind area.In practice, the ice chest in air separation plant is also a source of noise pollution, mainly due to saturating in ice chest
Flat expanding machine is a high-speed rotating equipment, and revolving speed per minute reaches tens of thousands of turns, and expanding machine generates while high speed rotation
Vibration, which is transmitted by the pipeline and ice chest connecting with expanding machine, to generate high-frequency noise.By theory
It calculates, a revolving speed is that vibration frequency caused by 30000 turns of expanding machine is 250HZ per minute, which causes phase therewith
Pipeline even and ice chest generate vibration, and through on-the-spot test, pipeline and ice chest can generate 76dBA, 1600 ~ 2500HZ and
The high frequency noise of two kinds of frequencies of 57.3dBA, 500HZ.
The improvement key of high frequency noise is exactly to reduce vibration, and the revolving speed of expanding machine itself determines vibration caused by itself
Frequency, the frequency are unmodifiable.So the resonance caused by the pipeline and ice chest steel construction being attached thereto can only be reduced.
Equipment of the condenser/evaporator as being directly connected to expanding machine by pipeline, the support pattern in ice chest are usual
It is all to be fixed with ice chest using welding or bolt using fashioned iron.The vibration that expanding machine generates is transferred to condensation evaporation by pipeline
Device causes condenser/evaporator to vibrate, and the fashioned iron which passes through condenser/evaporator again is transferred to ice chest, and ice chest is caused to vibrate, from
And ice chest is made to produce high frequency noise.Since the support of condenser/evaporator can not be detached from ice chest, so high frequency caused by resonating
Noise can only take measures to be reduced and cannot be completely eliminated.
In the prior art, the noise generated for solid vibration takes vibration isolation measure, is a kind of to weaken sonic propagation of making an uproar
Effective means.
Also there is the damping by increasing structure itself, to reduce the vibration of structure.The support construction of usual condenser/evaporator
For stainless steel square tube, by filling weight in stainless steel square tube to increase the self weight of supporting structure, filling is mixed in square tube
Solidifying soil is an effective method, however is cryogenic refrigeration operating condition in the ice chest of air separation plant, the running temperature in ice chest
It is at -20 DEG C hereinafter, infeasible as filler which results in concrete is chosen.
For this purpose, we have developed a kind of condenser/evaporator support construction of damping noise reduction suitable for -20 DEG C or less low temperature.
Utility model content
The utility model aim is to provide a kind of suitable for -20 DEG C or less low temperature for overcome the deficiencies in the prior art
The condenser/evaporator support construction of damping noise reduction.
In order to achieve the above objectives, the technical solution adopted in the utility model is: the condenser/evaporator of damping noise reduction supports knot
Structure includes multiple groups square tube component arranged in parallel；Square tube component described in every group includes square tube；The upper table of the square tube
Heat-insulating shield is provided on face；The lower surface at the both ends of the square tube is respectively arranged with channel steel；The both ends of the square tube are respectively set
On different ice chest crossbeams, the channel steel is used to limit the outer end of square tube and the relative position of corresponding ice chest crossbeam；Institute
It states filled with casting 6# silicon sand in square tube, the both ends of the square tube block respectively.
Preferably, the channel steel is located at the inside of corresponding ice chest crossbeam.
Preferably, the weight of casting 6# silicon sand is greater than half in every prescription tube assembly, and 10 dBA can be effectively reduced in noise.
Due to the application of the above technical scheme, the utility model has the advantage that compared with prior art
The condenser/evaporator support construction of damping noise reduction described in the utility model is suitable for -20 DEG C or less low temperature situations,
And after the self weight of the condenser/evaporator support construction of damping noise reduction doubles, 10 dBA can be effectively reduced in noise.
