Description
Technical field
The present invention relates to a kind of improvement of condenser/evaporator support construction, refer in particular to a kind of being suitable for -20 DEG C or less low temperature
The condenser/evaporator support construction of damping noise reduction.
Background technology
The noise abatement of air separation unit is also in industry 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 rotating 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 being connect with expanding machine, to generate high-frequency noise.By theory
It calculates, vibration frequency is 250HZ caused by the rotating speed expanding machine per minute for being 30000 turns, 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 rotating speed of expanding machine itself determines vibration caused by itself
Frequency, the frequency are unmodifiable.It resonates caused by the pipeline and ice chest steel construction being attached thereto so can only reduce.
Equipment of the condenser/evaporator as being directly connected to by pipeline with expanding machine, the support pattern in ice chest are usual
All it is to be fixed using welding or bolt with ice chest using shaped steel.The vibration that expanding machine generates is transferred to condensation evaporation by pipeline
Device causes condenser/evaporator to vibrate, which is transferred to ice chest by the shaped steel of condenser/evaporator again, 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 resonance
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 dead weight of supporting structure, filling is mixed in square tube
Solidifying soil is an effective method, however is cryogenic refrigeration operating condition, the running temperature in ice chest in the ice chest of air separation plant
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 the damping noise reduction suitable for -20 DEG C or less low temperature.
Invention content
A kind of damping suitable for -20 DEG C or less low temperature is provided the invention aims to overcome the deficiencies in the prior art
The condenser/evaporator support construction of noise reduction.
In order to achieve the above objectives, the technical solution adopted by the present invention is：The condenser/evaporator support construction of damping noise reduction, including more
Group square tube component arranged in parallel；Square tube component described in every group includes square tube；It is provided on the upper surface of the square tube
