Description
[technical field]
The utility model relates to a kind of wet type natural ventilation counterflow cooling tower.
[background technology]
Power plant's host machine cooling system adopts wet type natural ventilation counterflow cooling tower, and during cooling system small scale, cooling tower size is less, and always suppose in design that in tower, air flow method is even, therefore the filler of whole cooling tower adopts phase co-altitude and same piece spacing.And in fact due to the factor such as resistance of air inlet rain belt, the distribution of air-flow in tower is also uneven, and the flow velocity at Ta Nei center is lower, and ventilation is less, strengthens successively from tower center to periphery air inlet direction ventilation.Domestic project have Large Towers adopt filler not contour, etc. a pitch of fins arrange, namely the water-sprayed filler sheet spacing of whole tower is identical, but minimum at the packing height of tower central area, increase packing successively from tower center to periphery air inlet direction, the maximum discrepancy in elevation reaches 0.75m.This kind of arrangement also can make the ventilation of zones of different in tower and cooling load match, but spraying and splashing facility is highly different apart from splashing down of filler top, spill lack of homogeneity, and the packed height of the periphery of distalmost end is the highest, spraying and splashing facility highly should in rational scope apart from splashing down of filler top, because this increasing whole tower water distribution height, make water circulating pump energy consumption higher.
[utility model content]
In order to solve the problems of the prior art, the utility model proposes a kind of spraying and splashing facility and spilling even and that energy consumption is lower wet type natural ventilation counterflow cooling tower.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of wet type natural ventilation counterflow cooling tower, in cooling tower, packing is set, the sheet spacing of centre of cooling column region packing is larger, the sheet spacing of packing from centre of cooling column region to cooling tower centered region again to cooling tower neighboring area then reduces successively, the i.e. corresponding packing of increase successively surface area per unit volume, end face, the bottom surface of all packings are concordant, above packing, sparge pipe is set along tower cylinder inwall, each sparge pipe setting height(from bottom) is unified, spraying and splashing facility installed by sparge pipe, and each spraying and splashing facility setting height(from bottom) is unified.
Further, packing adopts film-type plastic water showering filling.
Further, packing is arranged and is centrosymmetric with centre of cooling column.
Further, packing adopts shelf type or suspension type to support installation.
The utility model is larger in the sheet spacing of the less packing of tower central area ventilation, strengthen successively from tower center to periphery air inlet direction ventilation, the sheet spacing of packing then reduces successively, and namely the corresponding filler of increase successively surface area per unit volume, makes ventilation and cooling load match.Relative to the not contour layout of packing, the end face, the bottom surface that become the packing that a pitch of fins is arranged are concordant, and sparge pipe setting height(from bottom) is unified, the also unification of spraying and splashing facility setting height(from bottom), spraying and splashing facility apart from packing end face splash down highly consistent, water spray spills evenly, good cooling results.Whole tower packing height is identical, and water distribution is highly low, and circulating pump head is low, saves and runs power consumption.
Compared with prior art, the ventilation of zones of different in tower and cooling load is not only made to match, improve the radiating effect of cooling tower, reduce outlet water temperature and generating set back pressure, increase the gene-ration revenue of unit or save coal-fired expense, and make spraying and splashing facility keep the end face distance apart from packing consistent, water spray spills evenly, improves radiating effect, reduces water distribution height simultaneously, reduce recirculated water pump lift, save power consumption.

Fig. 2 is elevational schematic view of the present utility model;
Wherein: 1-centre of cooling column region, 2-cooling tower centered region, 3-cooling tower neighboring area, 4-sparge pipe, 5-spraying and splashing facility, 6-water distribution vertical shaft, 7-air inlet ring beam, 8-air inlet trickle rain belt, 9-tower pillar, 10-tower cylinder.
[detailed description of the invention]
Below in conjunction with embodiment, the utility model is described in further detail.
See Fig. 1 and Fig. 2, wet type natural ventilation counterflow cooling tower of the present utility model, in cooling tower, air inlet ring beam 7 arranges packing, adopt film-type plastic water showering filling, due to the resistance of the air inlet trickle rain belt 8 between tower pillar 9, the skewness of air-flow in tower, according to the gravity-flow ventilation feature of zones of different in tower, packing is by different sheet pitch arrangement.According to the size of cooling tower soaking filler cross section diameter, Ke Congta center is divided into two and above region around tower.Centre of cooling column region 1 ventilation is less, the sheet spacing of packing is larger, strengthen successively from tower center to periphery air inlet direction ventilation, the sheet spacing of packing from centre of cooling column region 1 to cooling tower centered region 2 again to cooling tower neighboring area 3 then reduces successively, namely correspondingly increase filler surface area per unit volume successively, ventilation and cooling load are matched raising cooling effectiveness.End face, the bottom surface of all packings are concordant, and packed height is identical, and sparge pipe 4 setting height(from bottom) is unified, the also unification of spraying and splashing facility 5 setting height(from bottom), spraying and splashing facility 5 apart from packing end face splash down highly consistent, water spray spills evenly, good cooling results.Whole tower packing height is identical, and water distribution vertical shaft 6 water distribution is highly low, and circulating pump head is low, saves and runs power consumption.
Further, all packings are arranged and are centrosymmetric with centre of cooling column; Packing can adopt shelf type or suspension type to support and be arranged in tower cylinder 10.
The utility model system is applicable to the wet type natural ventilation counterflow cooling tower of thermal power plant or nuclear power plant, according to the gravity-flow ventilation feature of zones of different in tower, tower central area ventilation is less, strengthen successively from tower center to periphery air inlet direction ventilation, the sheet spacing of packing then reduces to arrange from tower center to periphery successively, namely the corresponding filler of increase successively surface area per unit volume, makes ventilation and cooling load match; The either flush of packing simultaneously, sparge pipe setting height(from bottom) is unified, the also unification of spraying and splashing facility setting height(from bottom), and spraying and splashing facility is highly consistent apart from splashing down of packing end face, and water spray spills evenly.
The utility model improves the radiating effect of cooling tower, reduces outlet water temperature and generating set back pressure, increases the gene-ration revenue of unit or saves coal-fired expense.Whole tower packing height is identical, and water distribution is highly low, and circulating pump head is low, saves and runs power consumption.The utility model be improve cooling effectiveness, energy-conservation, consumption reduction design.
