Description
Technical field
The present invention relates to a kind of improvement of main heat exchanger support construction, a kind of subtracting suitable for -20 DEG C or less low temperature is refered in particular to
Shake the main heat exchanger support construction of noise reduction.
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 main heat exchanger as being directly connected to expanding machine by pipeline, the support pattern in ice chest is usually all
It is to be fixed with ice chest using welding or bolt using fashioned iron.The vibration that expanding machine generates is transferred to main heat exchanger by pipeline,
Main heat exchanger is caused to vibrate, the fashioned iron which passes through main heat exchanger again is transferred to ice chest, causes ice chest to vibrate, to make ice chest
Produce high frequency noise.Since the support of main heat exchanger can not be detached from ice chest, so high-frequency noise caused by resonating can only be adopted
It takes measure to be reduced and cannot completely eliminate.
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 main heat exchanger is
Stainless steel square tube fills coagulation by filling weight in stainless steel square tube to increase the self weight of supporting structure in square tube
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-
20 DEG C hereinafter, infeasible as filler which results in concrete is chosen.
For this purpose, we have developed a kind of a kind of main heat exchanger support knot of damping noise reduction suitable for -20 DEG C or less low temperature
Structure.
Summary of the invention
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 main heat exchanger support construction of noise reduction.
In order to achieve the above objectives, the technical solution adopted by the present invention is that：A kind of main heat exchanger support construction of damping noise reduction includes
Multiple groups square tube component arranged in parallel；Square tube component described in every group includes square tube, heat-insulating shield and spring damper；Institute
It states and is provided with heat-insulating shield on square tube upper surface；The both ends of the square tube pass through spring damper respectively and different ice chest cross are arranged in
Liang Shang；Filled with casting 6# silicon sand in the square tube, the both ends of the square tube block respectively.
Preferably, casting uses the weight of 6# silicon sand greater than the half of the weight of square tube component, noise in every prescription tube assembly
10 dBA can be effectively reduced.
Due to the application of the above technical scheme, the present invention has following advantages compared with prior art：
The main heat exchanger support construction of damping noise reduction of the present invention is suitable for -20 DEG C or less low temperature situations, and when damping is dropped
After the self weight for the main heat exchanger support construction made an uproar doubles, 10 dBA can be effectively reduced in noise.
Detailed description of the invention
Technical scheme of the present invention is further explained with reference to the accompanying drawing：
Attached drawing 1 is the main view of the main heat exchanger support construction of damping noise reduction of the present invention；
Attached drawing 2 is the top view of the main heat exchanger support construction of damping noise reduction of the present invention；
Wherein：1, square tube；2, heat-insulating shield；3, spring damper；4, ice chest crossbeam.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is described in further details.
Attached drawing 1-2 is the main heat exchanger support construction of damping noise reduction of the present invention, arranged in parallel comprising multiple groups
Square tube component；Square tube component described in every group includes square tube 1, heat-insulating shield 2 and spring damper 3；1 upper surface of square tube
On be provided with heat-insulating shield 2；The both ends of the square tube 1 pass through spring damper 3 respectively and are arranged on different ice chest crossbeams 4；Institute
It states filled with casting 6# silicon sand in square tube 1, the both ends of the square tube 1 block respectively.The 6# silicon sand must be dried.The 6#
The loading of silicon sand is greater than 56 kilograms.
By test of many times, the weight of casting 6# silicon sand is greater than the half of the weight of square tube component in every prescription tube assembly
Afterwards, 10 dBA can be effectively reduced in noise.
Due to the application of the above technical scheme, the present invention has following advantages compared with prior art：
The main heat exchanger support construction of damping noise reduction of the present invention is suitable for -20 DEG C or less low temperature situations, and when damping is dropped
After the self weight for the main heat exchanger support construction made an uproar doubles, 10 dBA can be effectively reduced in noise.
