Description
Technical field:
The present invention relates to municipal heat supply process field, relate in particular to a kind of heat exchange station and manufacture method thereof of vibration and noise reducing.
Background technology:
Heat exchange station is the place that is connected of heat supply network and hot user in heating system, effect is that heat energy is transferred in hot custom system from heat supply network, user's request is provided, and the heating medium parameter that heat supply network is carried is regulated, transform to the desired parameter of subscriber equipment and quantity, control the economical operation state of user's the best.Existing heat exchange station operated by rotary motion is in the detached building of community, in heat exchange station, arrange between heat exchange, janitor's room, control room and kitchen, lavatory etc., the heat exchange station building area needed is larger, development along with concentrated supply of heating in the city, city old city particularly, existing building is intensive, does not allow newly-built independent heat exchange station, has affected user's normal heat supply.In addition, during heat supply running equipment, equipment and pipeline can produce larger vibration and noise problem, that is: the heat exchange station of general highrise building is arranged at basement and affects the quality of life of surrounding resident.The absorption vibration denoise method of tradition heat exchange station, the standby base of bottom laying groove steel of tangible heat exchange unit, the body of wall inwall adds damping material simultaneously, simultaneously, can be at pipeline upper berth handicapping damping paint, but this absorption vibration denoise method is too simple, and effect is small.
For solving this technical problem, some technological improvements for the vibration and noise reducing of pump house or pipeline have appearred on the market, as Chinese patent application, 201120338008.0 disclose a kind of vibration-damping noise-reduction type natural gas line.Its technology point is: natural gas line is coated with the vibration and noise reducing composite material, and the vibration and noise reducing composite material comprises high internal damping material layer (1), the first vibration damping absorbent treatment (2), butyl rubber layer (3), the second vibration damping absorbent treatment (4) and a top layer aluminium sheet (5) from inside to outside successively.It adopts multilayer materials to coat natural gas line, can effectively reduce the pipeline radiated noise.This technology; be the same center of circle between its each damping material layer and pipeline; reach noise reduction in the straight tube stage out of question, still, in the elbow stage, have technical problem; while especially being applied to heat distribution pipeline (elbow); the excessive extruding insulation layer of instrumentation tubes thermal stretching amount, make the insulation layer attenuation even instrumentation tubes and outer tube be close together, the heat insulation effect variation; the outer tube temperature raises, and then has destroyed the topping (anticorrosive coat of outer tube outer wall) of outer tube.Final energy consumption increases, if topping is destroyed, and outer tube corrosion speedup, potential safety hazard increases.And, in heat exchange station, most pipelines are the elbow shape, the part of straight tube seldom, so, has also been brought the problem of noise increase.
Chinese patent application for another example, 201110054805.0 disclose pipe vibration-damping noise-reduction method and periodic damping structure, and its technology point is, is to adhere to a plurality of damping fins in the pipeline outside by certain interval.Periodic damping structure, comprise pipeline and damping layer, and damping layer is at pipeline external, and damping layer is a plurality of damping fins, a plurality of damping fins by certain interval along pipeline axial or circumferentially stick to the pipeline outside.Be that pipeline is continuous, and a plurality of damping fin is by periodic arrangement.This damping structure can play the effect of vibration and noise reducing, but, defect as above, while being applied in heat exchange station inside, more because of the inner elbow of heat exchange station, the structure of this periodic arrangement can't be useful in elbow part, so, this technology solves the vibration and noise reducing problem of straight tube, and can't solve the vibration and noise reducing problem of the inner bend pipe of heat exchange station.
Chinese patent application 200920072860.0 discloses a kind of air conditioning heat pump machine room pipeline vibration and noise reducing device for another example, comprises cushion blocking, cushion blocking be laid on pipeline and hold or the suspension bracket of supporting pipeline between.Cushion blocking is technological means commonly used in absorption vibration denoise method, but, if heat exchange station is used merely cushion blocking, its effect is small, can't reduce the propagation between vibration and building, and the thickness that cushion blocking is used increases, although can increase the effect of vibration and noise reducing, be unfavorable for the heat radiation of heat exchange unit.
And for example Chinese patent application 201210186047.2 discloses a kind of vibration and noise reducing device, comprise upper flat plate, lower flat board, also comprise the bridge structure, between the plane of upper flat plate and lower flat board, be connected and fixed the bridge structure, the bridge structure is built by hollow stem, fills solid particle in hollow stem.Solid particle is filled in hollow stem, takes full advantage of the space of hollow stem, simple in structure, can effectively improve the effectiveness in vibration suppression of vibration and noise reducing device, does not need again additional space; Variation and scattering by the bridge structure to the vibrational waveform of transmission, the effectiveness in vibration suppression of raising vibration and noise reducing device.By being filled in phase mutual friction and the further consumption systems vibrational energy of collision between the solid particle in hollow stem, to improve effectiveness in vibration suppression.Although this structure can play the effect of vibration and noise reducing,, this structure can increase the volume of heat exchange station, especially, when heat exchange station is set up in heat exchange station transformation or new high-rise community, can't be useful in the zone of narrow space.
For solving this technical problem, need to occur a kind of simple in structure, easy to use, can xegregating unit and building, transmitting vibrations, all in the heat exchange station absorbed inside, do not reduce the overseas publicity of noise by noise, obtain good, quiet heating environment, reduce heat exchange station and the manufacture method thereof of heat exchange station to a kind of vibration and noise reducing of the noise effect of surrounding resident.
