Description
Technical field
What the present invention relates to is a kind of ultra-low noise cooling tower, particularly a kind of employing hyperbolicity arc dropping plate, and the oval cross section water leg, the ultra-low noise cooling tower of dropping plate and water leg integral structure belongs to the fluid engineering technical field.
Background technology
Cooling tower buzz is the significant problem that users, cooling tower manufacturing enterprise, environment department very pay close attention to the pollution of surrounding environment always, the achievement in research of current ultra-low noise cooling tower axial flow blower has reduced the aerodynamic noise of cooling tower significantly, and the trickle noise has risen to the main noise source of cooling tower, and lot of domestic and foreign cooling tower design department still fails to improve the effective measures that propose to reduce the trickle noise so far.At present, Japan's letter and cooling tower company, Taiwan good opportunity, a gold day water tower company all adopt and install the porous sound absorption pad additional, but its noise reduction is only about 2dB (A), and be only limited to the application of small-sized tower, and fibre shedding appears in sound absorption cushion material sometimes, fall in the system and can stop up the water pipe runner, severe patient can cause line clogging to have an accident.It is to install noise elimination, acoustic screen on every side additional in cooling tower trickle district so far that domestic cooling tower began from the eighties always, but can cause the air side flow resistance to increase, the tower air quantity is advanced in influence, thereby influences cold effect or increase fan energy consumption, takies too much place and can cause aerodynamic noise to increase again.Also have and adopt the height that reduces the countercurrent tower air intake or adopt cross flow cooling tower, but these two kinds of method noise reductions are not obvious.In the prior art, the patent No. is to adopt one group of arc bucket shape dropping plate and collector pipe for the utility model patent that the ZL02265768.1 name is called " environment-friendly type ultra-low noise cooling tower ", make the water that falls into aqua storage tank originally fall into dropping plate earlier, back inflow two side collector pipes slowly slow down, reduce trickle sound, but the air inversion that this method enters from the air intake shutter and on, when flowing through arc bucket shape dropping plate, the air flow resistance that runs into is big, this method also need be provided with the water storage dish in the air-inlet window bottom, collection has increased manufacturing cost from the water that the dropping plate back gutters down.
Summary of the invention
For deficiency and the defective that overcomes prior art, the present invention designs a kind of water leg and dropping plate integral structure, can effectively reduce the cooling tower of trickle noise, the present invention includes water collection device, blower fan, water inlet pipe, nozzle, filler, and the integral structure of forming by dropping plate, big water leg and little water leg.Dropping plate is a hyperbolicity arc, becomes the big water leg of cross section ovalize, little water leg to be positioned at the dropping plate back side, big water leg top in its bottom bend, and big water leg and little water leg all link into an integrated entity with dropping plate is smooth.Dropping plate, big water leg and little water leg integral structure are installed between filler and the air intake shutter.Two big drainpipes respectively with the two ends vertical connection of big water leg, two weepers respectively with the two ends vertical connection of little water leg, the weeper two ends seal with blank flange, big drainpipe one end seals with blank flange, the other end is connected with the pump suction main by flange, and weeper links to each other with big drainpipe by tube connector.
Dropping plate, big water leg and little water leg integral structure and with mutual being connected of drainpipe, also can adopt following structure: the two ends of big water leg and little water leg are connected with shrouding respectively, on the dropping plate of little water leg bottom and dropping plate junction, have some slotted eyes, bottom at big water leg has several osculums, the main sewer level is installed in below the interior big water leg of cooling tower, big water leg is communicated with main sewer by the drainpipe that is vertically mounted on below the osculum, main sewer one end seals with blank flange, and the other end is connected with the pump suction main by flange.
Flow through behind the cooling water absorption condensation heat of condenser, temperature raises, be sprayed on evenly on the filler by nozzle through water inlet pipe that to form moisture film dirty, moisture film flows into big water leg earlier through dropping plate after hyperbolicity arc dropping plate slowly slows down, the water droplet at a small amount of dropping plate back side flows into little water leg, finally import the pump suction main by weeper and big drainpipe, needn't adopt big aqua storage tank, greatly reduce the trickle noise, and reduce the static lift value of water system.Because the cross section of big water leg is ellipse, is the convergent gradually expanded form by the air flow channel that forms between the big water leg, the air flow that enters from the air intake shutter has obviously reduced gas-flow resistance when flowing, and has increased cooling effect.
Beneficial effect of the present invention:
The present invention starts with from the several sources of trickle and reduces the trickle noise, and can make full use of the overbottom pressure of recirculated water, reduces the static lift value of water system, saves the energy consumption of water system.Need not at the wind inlet section place sound insulation facility to be installed, overall structure is simple, and gas-flow resistance is little, can obviously reduce the water tower noise, and warp is to 2200m
3/ h and 100m
3Two model machine tower actual measurements of/h noise, the former than the low 5dB of national standard ultra-low noise cooling tower (A) about, about the low 3.5dB (A) of latter's noise ratio national standard ultra-low noise cooling tower, this invention achievement will have fabulous popularizing application prospect after implementing in " Olympic Games ", " Expo " engineering, and can squeeze into the international market.Have remarkable economic efficiency and social benefit.
