Description
Technical field
The present invention relates to the high-order tower composition of a kind of used in nuclear power station structure, more particularly, the high-order tower that the present invention relates to a kind of used in nuclear power station water collector and comprise water collector.
Background technology
Cooling tower is industry and the civilian cooling device being widely used, and in electric power cooling device, adopts cooling tower maximum, and the hot water of conventional cooling tower is experience water spray district, moisture film district and rain belt three parts in cooling and landing process.High-order tower is by raising water collector, shorten rain belt, reach and reduce circulating pump head, saving pump power, reduce rain belt noise, no longer need to consider with cooling tower tower diameter increase, that cold air passes through rain belt is long, a difficult problem that causes central region air distribution ability to weaken and cannot calculate and assess, the existing application of thermal power plant and nuclear power plant at home and abroad.
Relatively more conventional is cooling stack now, cooling stack utilizes air in aqueous vapor heat transfer process to be heated, the suction force that tower inner air and outer air density contrast is produced, therefore air does not need energy source consumption in flow process, there is energy-saving significance, in large-scale cooling project, be widely applied.
Cooling stack is mainly comprised of sparge pipe, shower nozzle, packing layer, pillar and the ground collecting-tank etc. of tower cylinder, tower cylinder bottom.Hot water is cooling in cooling tower, hot water promotes and enters cooling tower distribution well through water circulating pump, be dispensed to sparge pipe, through the peptizaiton of sprinkler tip, splash down into water droplet and be evenly distributed on filler, then become fine little moisture film by fillers dispersed, with cold air fully heat exchange in packing layer from bottom to top, after hot water is cooling by air, by filler bottom, fall into cooling tower collecting-tank, dropping process forms rain belt.Part cooling water evaporation becomes the hot-air forming after water vapour and heated air blending to blow out outside tower under buoyancy.
Comparatively conventional use is counter flow type natural draft cooling tower now, the circulating path of the hot and cold two media of this cooling tower is: the hot water after heat exchanger heat exchange is recycled water pump lifting and enters distribution well in tower, by sparge pipe to the water distribution of range pipe gravity type, after being sprayed into filler, shower nozzle forms moisture film, realize and the abundant heat exchange of cold air of from bottom to top advancing, cooling water falls into collecting-tank at the bottom of by filler, through water circulating pump, again promotes and enters heat exchanger, become again hot water, so iterative cycles.Wherein, cooling medium is cold air, so, for each piece filler provides the cold air of " guaranteeing both quality and quantity ", be the key of carrying out cooling tower air distribution water distribution design.The rain belt of cooling tower filler bottom possesses certain cooling capacity, but its Main Function is to provide enough cold airs, because the air-admitting surface of cooling tower affects greatly the gas-flow resistance of the air-flow distribution in tower and air intake mouth region, the too small meeting of air inlet causes that cooling tower inlet air flow velocity is too high, wind speed profile is inhomogeneous in tower, and air inlet is too high, will increase the total height of recirculated water pump lift and tower, increased cost and the operating cost of cooling tower.According to the comparative analysis of test data and service data, the air-admitting surface of cooling stack generally gets 0.3～0.4 with the ratio of drenching area, realizes this object and need to consume the power that exceedes water circulating pump 1/3rd.
In actual use, there is following subject matter in counter flow type natural draft cooling tower:
1. circulating pump head is high: water circulating pump except provide in cooling water circulation process along journey and local head loss, also need to provide the static lift of the distribution well height of water level including the height of rain belt;
2. rain belt noise is large: tower is larger, and rain belt height is higher, and rain belt noise is larger, according to measured data, and 12000m
2the noise on conventional cooling stack tower limit reach 80dB, the work on cooling tower periphery resident or operator on duty and life impact are larger;
3. the existence of rain belt makes air enter resistance in the process of filler to strengthen gradually, and along with the increase of column area, the distance through rain belt of air is longer, tower central region needs enough cold airs to become more difficult, if unilaterally raise air inlet height, by the problem of aggravation problem 1 and 2, and the cost of tower is increased;
4. the cold air that enters cooling tower middle part has been heated in rain belt simultaneously, makes the closer to middle part, and further increasing containing hot water capacity of air, worsens the cooling condition at middle part.
Now, the problem existing for existing counter flow type natural draft cooling tower, the existing high-order water cooling tower of receiving is in operation both at home and abroad, construction is quite a few what build, adopts and be arranged in parallel side by side, along tower diameter direction and female pipe equidistance place that catchments, arranging highly of water collecting plate equates there is no the discrepancy in elevation.
In the high-order cooling tower of the type, in order to meet incoming air area requirement, its water collecting plate need to be arranged to the larger gradient, cause the real area of water collecting plate to increase, and the vertical gradient of water collecting plate is large and pump head increase can make water droplet kinetic energy increase, area change splashes.For preventing that water droplet is splashed into outside tower, need to set up splashproof filler, each row's water collecting plate need to configure a water leg, has increased construction cost and the choke area of water leg.
In addition; water collecting plate, water leg etc. generally select conventional plastics even to select concrete material; difference in functionality and the corrosion failure pattern of failing for parts; the selection of material targetedly; cause rapid wear easily to lose unit failure; cause termination of pumping shutdown or water body aeration, the cavitation conditions that follows pump operation worsens.
