Abstract
The utility model discloses a glass fibre reinforced plastic cooling tower with a repressing noise device, comprising an upper tower body, a middle tower body, an air intake section, and a chassis. The center of the glass fibre reinforced plastic cooling tower is provided with a central water inlet pipe which is connected with a rotary water distributor. The upper tower body is provided with a blower. The middle tower body is provided with packing. The air intake section is provided with a silencing sloping plate or half soft fillers. The chassis is provided with silencing fillers. The circumference of the air intake section is provided with a silencing screen. The blower adopts a swinging-arm type automatic tensioning belt reducer. The utility model has the advantages of novel design, reasonable structure, micro floating water, low noise, and high cooling effect.
Description
The utility model relates to cooling tower, relates in particular to micro floating water mute type glass fibre reinforced plastics cooling tower.
Along with developing rapidly of Chinese national economy, living standards of the people improve constantly, environmental administration is more and more tighter to the control of city environmental pollution, and the demand of cooling tower also increases along with expanding economy, and it all be can't do without in departments such as refrigeration, air-conditioning, medicine, health.The water that wafts of cooling tower, noise has become the part of current city environmental pollution.
The purpose of this utility model provides a kind of micro floating water mute type glass fibre reinforced plastics cooling tower.
In order to achieve the above object, the utility model is taked following measures: it comprises tower body, middle tower body, wind inlet section, chassis, the tower center is provided with the center water inlet pipe and joins with turning spurt water device, last tower body is provided with blower fan, middle tower body is provided with packing, feature is to be provided with semi soft packing at wind inlet section, be provided with noise barrier around wind inlet section, be provided with the noise reduction filler on the chassis, blower fan adopts rocker-arm auto-tensioning belt decelerator.
Advantage of the present utility model: 1. blower fan adopts belt reduction unit to eliminate the gear drive noise, establishes the expansion air duct in last tower body upper end, and it can increase the blower fan aeroperformance, changes sound source radiation approach and absorption portion sound source, reduces damp-heat air and refluxes.2. establish soft-filler in the inlet section section, it is distributed in air intake space according to certain spacing, and the drop of current is almost nil like this, and the speed that water flows to before the chassis is also very little, has reduced the trickle noise.Simultaneously, the installation of semi soft packing prolongs the time of contact of current and air, also helps improving the cold effect of cooling tower.Or establish the noise reduction swash plate at wind inlet section, and can slowly slip into the chassis along swash plate by the cooling water behind the filler, current speed when arriving the chassis reduces greatly like this, thereby has reduced the noise that the current collision produces.We know that collision object is firm more mutually, and the noise of collision is also just big more, and according to this principle, one deck silent packing is laid at the place on the chassis, to reduce to collide the noise of generation.Adopt above-mentioned measure can make whole tower noise reduce 5-8dB (A), establish noise barrier around wind inlet section, can absorb the trickle noise, whole tower can reduce 2-3dB (A) again.3. according to the micro floating water turning spurt water device of hydraulic turbine principle design, uniform bailing bucket around the water-locator rotational shell, water-locator fixedly inner core pedestal is made the runner of circular arc, force current to form tangential direction speed, impact bailing bucket, make shell drive water distributor and rotate, the apopore of water distributor vertically downward.Because the apopore of this water distributor vertically downward, can prove, the hydrone of water outlet is the shortest at the move distance in space, the contact area minimum of minimum, water outlet of time and counter-flow air, the water distributor aperture is big, and flow velocity is little, has reduced stroke speed, reduced the generation of foam, therefore producing this type of water-locator can significantly reduce the water loss that wafts.
