Description
Technical field
The utility model belongs to thermal power plant and nuclear electric power generation field, particularly relates to the one high position adopted for improving high-order receipts water cooling tower cooling effectiveness and receives the non-homogeneous water distribution system of water cooling tower.
Background technology
High-order receipts water cooling tower uses at home and day by day increases, and the high-order water distribution system receiving water cooling tower is conventional design at present, and namely spray density distributes along water distribution face uniform diameter.But cooling tower is bulky, in tower, space is huge, after ambient wind enters from cooling tower bottom air inlet mouth, in tower, velocity flow profile is uneven everywhere, simultaneously due to the impact of spray density uniform distribution, again destroy air force field distribution in tower, the cooling capacity of cooling tower is not fully used, gas-water ratio is lower, and cooling tower cooling effectiveness is lower.
One is disclosed in patent [201310132397.5], high-order water collector and comprise the wet cooling tower of this device, this high position is received water cooling tower and is adopted uniform water distribution mode, in tower, aerodynamic field destroys larger skewness, in tower, cooling capacity is not fully used, gas-water ratio is lower, and cooling effectiveness is lower.
Utility model content
The utility model is in order to solve the problem, overcome an existing high position and receive water cooling tower water distribution mode Problems existing, provide a kind of high-order receipts water cooling tower water distribution system, reduce spray density to the impact of air uniformity in tower, make full use of the cooling capacity in tower, improve the high-order cooling effectiveness receiving water cooling tower.
The technical solution adopted in the utility model is as follows:
The non-homogeneous water distribution system of a kind of high-order receipts water cooling tower, comprise the water distributing area being positioned at cooling tower, the water distribution of described water distributing area adopts nonuniform mutation operator and subregion to arrange, the diametric(al) namely along high position receipts water cooling tower takes a kind of nonuniform mutation operator mode from inside to outside.
Described water distributing area partitioned mode is: centered by the vertical axis of cooling tower, is outwards divided into three annular sections of different radii successively, i.e. A district, B district and C district.
The pass of the water distribution radius of described three water distributing areas is: A district≤B district≤C district.
The spray density of described three water distributing areas closes and is: > C district of > B district of A district.
When ensureing that total spray density amount is constant, the radius of the water distribution of described three water distributing areas is: A district water distribution radius:
b district water distribution radius:
c district water distribution radius:
wherein r is equivalent radius, is this water distributing area, place radius and the ratio of water distribution zone radius maximum.
The spray density of described three water distributing areas is: A district: 1.05q≤wq≤1.15q; B district: 0.85q≤wq≤q; C district: 0.7q≤wq≤0.8q, spray density when wherein q is uniform water distribution.
The beneficial effects of the utility model are as follows:
Outside air enters high-order to be received through catchment area after water cooling tower, and because the certain guide effect of captation region to air makes that high-order to receive water cooling tower central area air velocity maximum, outer peripheral areas air velocity is minimum.Because the maximum and zone line coolant water temperature of zone line air velocity still has gap apart from its cooling limit wet bulb air themperature, namely zone line cooling capacity also has room for promotion, ensureing under the condition that trickle gross density is constant, for utilizing its cooling capacity as far as possible, therefore strengthen zone line spray density, namely make central area can cool more cooling water.
Outer peripheral areas is not enough due to air mass flow, affects the cooling of its recirculated water, therefore for increasing its ventilation, improve cooling effectiveness, ensureing, under the condition that trickle gross density is constant, to reduce outer peripheral areas spray density, namely make the cooling water inflow of outer peripheral areas reduce, increase its ventilation.

In figure 1, high-orderly receive water cooling tower; 2, water distributing area; 3, captation.
Detailed description of the invention
Be described in more detail for the utility model in conjunction with the embodiments.
The non-homogeneous water distribution system of a kind of high-order receipts water cooling tower 1, comprise the water distributing area 2 being positioned at cooling tower, captation 3 in the below of water distributing area, the water distribution of water distributing area 2 adopts nonuniform mutation operator and subregion to arrange, the diametric(al) namely along high position receipts water cooling tower takes a kind of nonuniform mutation operator mode from inside to outside.Described water distributing area 2 partitioned mode is: centered by the vertical axis of cooling tower, is outwards divided into three annular sections of different radii successively, i.e. A district, B district and C district.
The pass of the water distribution radius of three water distributing areas 2 is: A district≤B district≤C district.
The spray density of three water distributing areas 2 closes and is: > C district of > B district of A district.
When ensureing that total spray density amount is constant, the radius of the water distribution of three water distributing areas 2 is:
A district water distribution radius:
b district water distribution radius:
c district water distribution radius:
wherein
for equivalent radius, be this water distributing area, place radius and the ratio of water distribution zone radius maximum.
The spray density of three water distributing areas 2 is:
A district: 1.05q≤wq≤1.15q; B district: 0.85q≤wq≤q; C district: 0.7q≤wq≤0.8q, spray density when wherein q is uniform water distribution, here is two specific embodiments:
Embodiment 1
A district scope:
spray density wqA=1.073q;
B district scope:
spray density wqB=q;
C district scope:
spray density wqC=0.8q.
Embodiment 2
A district scope:
spray density wqA=1.12q;
B district scope:
spray density wqB=0.9q;
C district scope:
spray density wqC=0.75q.
In the utility model, outside air enters and high-order receives through catchment area after water cooling tower, and because the certain guide effect of captation region to air makes that high-order to receive water cooling tower central area air velocity maximum, outer peripheral areas air velocity is minimum.Because the maximum and zone line coolant water temperature of zone line air velocity still has gap apart from its cooling limit wet bulb air themperature, namely zone line cooling capacity also has room for promotion, for utilizing its cooling capacity as far as possible, therefore strengthens zone line spray density.
Outer peripheral areas is not enough due to air mass flow, affects the cooling of its recirculated water, therefore for increasing its ventilation, improves cooling effectiveness, reduces outer peripheral areas spray density.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
