Description
Technical field
The present invention relates to a kind of method for governing pollution, especially relate to a kind of noise abatement method of underground substation.
Background technology
Expo transformer station is as underground ehv power transmission facility, and its pollutant sources mainly concentrate in transformer station's body.The aerodynamic noise that noise during the substation operation mainly produces from the noise that electric equipment produced such as main transformer and power distribution equipment and cooling system is main with medium and low frequency usually.This engineering is as the underground substation; Main transformer and power distribution equipment are full underground; The noise that produces can not influence the ground surrounding environment, and comparatively speaking, the aerodynamic noise of ground ventilating opening becomes the main Noise source of this engineering; Must in engineering design, take a series of effective control measures, guarantee that transformer station satisfies the national environmental standard requirement to the influence of acoustic environment on every side.
Summary of the invention
The object of the invention is exactly to provide in order to overcome the defective that above-mentioned prior art exists that a kind of method is simple, construction cost is low, can significantly reduce the noise abatement method of the underground substation of noise effect.
The object of the invention can be realized through following technical scheme: a kind of noise abatement method of underground substation, and it is characterized in that this method may further comprise the steps: 1) main transformer equipment is provided with vibration isolator; 2) transformer station is arranged on undergroundly, and transformer body chamber is an enclosed construction, and the transformer chamber gate is a soundproof door; 3) transformer body and radiator split are provided with, and cooling tower equipment is provided with in the hypogee; 4) each blower fan is provided with the air draft muffler, advances, is provided with sound absorption structure in the exhaust air shaft, advances, the exhaust air shaft top is provided with the sound absorption furred ceiling; 5) ground air draft well outlet built on stilts certain altitude, and the blinds baffle plate with good sound absorption and defening effect is set; 6) ground air draft well spacing is 80m～110m.
Blower fan in the described step 4) is provided with into, the air draft muffler.
Described ground air draft well is provided with four.
Compared with prior art, the present invention adopts full underground scheme, and main strong noise equipment is arranged in underground, and through the underground structure and the shielding action on the face of land, strong noise equipment such as main transformer, reactor, cooling tower are to ground acoustic environment not influence.The noise source that is positioned at ground mainly is downcast and 4 air draft wells, the design to each blower fan installed, the air draft muffler, sound deadening capacity is greater than 15dB.
Embodiment
Below in conjunction with specific embodiment the present invention is elaborated.
Embodiment
When substation equipment bid negotiation, strong noise equipment such as main transformer, blower fan, pump there is the sound level requirement, preferentially select low noise equipment for use, equipment such as main transformer are installed vibration isolator.Transformer station adopts full underground, and transformer body chamber is an enclosed construction, and the transformer chamber gate adopts soundproof door.The form that adopts transformer body and radiator split to arrange, cooling tower equipment all is arranged in the hypogee, reduces the surface noise source.Each blower fan has been installed the air draft muffler, and sound deadening capacity is greater than 15dB; Advancing, laying in the exhaust air shaft sound absorption structure with good sound absorption effect, advance, the exhaust air shaft top is provided with the sound absorption furred ceiling.Ground air draft well outlet built on stilts certain altitude, and the blinds baffle plate with good sound absorption and defening effect is installed, make the propagation of noise direction have stronger directive property, reduce near the surface noise of air draft well as far as possible.Above ground structure/structures rational deployment, minimum range 80m between 4 air draft wells, ultimate range 110m avoids producing the synergistic effect of many noise sources; The ground planting greening reduces the air draft noise effect.
Whole transformer station underground part sets up a concentrated air-intake shaft separately; The required air intakes of cooling such as VMC, process equipment and refrigeration plant that are used for all process equipment room ventilations of transformer station, air-conditioning system, public domain; All process equipment room ventilation and air conditioning systems of transformer station, process equipment and refrigeration plant etc. are useless in order to satisfy, the requirement of exhaust of hot air; Corresponding to 4 zone of F3/B3 converting equipment layer a regional centralized exhaust air shaft is set respectively; The air draft in each room and zone adopts the mechanical exhaust mode to drain into the regional centralized exhaust air shaft of respective regions respectively in the zone, and drains into outdoor through the exhaust outlet of concentrating the vertical shaft aerial part.
The cross section of the exhaust duct of each cooling tower is 2000 * 1500mm, and exhaust air rate is 88560m3/h.#1, #2 and #4 exhaust air shaft are being arranged in juxtaposition 4 cooling tower exhaust outlets; 4 cooling tower air draft mufflers that are arranged in juxtaposition are designed to one; Air draft muffler planar dimension is 6000 * 4900mm, and the muffler height is 3000mm, and bottom 500mm is an expansion segment; Top 500mm is a steady flow segment, and protection network is installed on the top.The bottom of reducer pipe and muffler is installed on each exhaust outlet connects, seal as base plate with corrosion resistant plate the bottom of muffler.The #3 exhaust air shaft have only a cooling tower exhaust outlet at present, only anechoic sheet is installed in 1/4th cross section, leave a blank in remaining cross section.
The air draft muffler of the mid portion exhaust outlet of 4 exhaust air shafts is designed to the air draft muffler of integral type; The muffler of the exhaust outlet that 4 exhaust duct cross sections are 1250 * 1000mm is 1 group; Sectional dimension is 3500 * 3200mm; The height of muffler is 3000mm, and bottom 500mm is an expansion segment, and top 500mm is a steady flow segment.Advance the noise effect of air draft well for further reducing, design is provided with sound absorption structure to entering the exhaust air shaft inboard, mainly is above the air draft muffler, to increase suspended absorber, further reduces the intensity that noise is outwards propagated.
