Abstract
The invention discloses a non-uniform water distribution system for a high-position water collecting cooling tower. The non-uniform water distribution system comprises a water distribution area located in the cooling tower, the water distribution of the water distribution area is in non-uniform arrangement and zoning arrangement; that is to say, a non-uniform arrangement mode is adopted from inside to outside in the diameter direction of the high-position water collecting cooling tower. The zoning mode of the water distribution area is that with the vertical axis of the cooling tower as the center, the water distribution area is sequentially divided into three annular areas of different radiuses outwards, and the three annular areas are an area A, an area B and an area C. The non-uniform water distribution system reduces the influence on air uniformity in the tower caused by water spraying density, the cooling capability in the tower is fully utilized, and the cooling efficiency of the high-position water collecting cooling tower is improved.
Description
Technical field
The invention belongs to thermal power plant and nuclear electric power generation field, especially relate to as improving high-order receipts water cooling tower
Cooling effectiveness and adopt a kind of high-order receive the non-homogeneous water distribution system of water cooling tower.
Background technology
At home using day by day increasing, the high-order water distribution system receiving water cooling tower is routine to high-order water cooling tower of receiving at present
Design, that is, spray density is along the distribution of water distribution face uniform diameter.But cooling tower is bulky, in tower, space is huge, ambient wind from
After cooling tower bottom air inlet mouth enters, in tower, velocity flow profile is uneven everywhere, simultaneously because the shadow that spray density evenly distributes
Ring, destroy air force field distribution in tower again so that the cooling capacity of cooling tower is not fully used, gas-water ratio is relatively
Low, cooling tower cooling effectiveness is relatively low.
One kind, high-order water collector and the wet type cooling comprising this device is disclosed in patent [201310132397.5]
Tower, this high position is received water cooling tower and is adopted uniform water distribution mode, and in tower, aerodynamic field destroys cooling in larger skewness, tower
Ability is not fully used, and gas-water ratio is relatively low, and cooling effectiveness is relatively low.
Content of the invention
The present invention, in order to solve the above problems, overcome the existing high-order problem receiving the presence of water cooling tower water distribution mode, provides
A kind of high-order receive water cooling tower water distribution system, reduce the impact to air uniformity in tower for the spray density, make full use of in tower
Cooling capacity, improve the high-order cooling effectiveness receiving water cooling tower.
The technical solution used in the present invention is as follows:
A kind of high-order receive the non-homogeneous water distribution system of water cooling tower, including the water distributing area in cooling tower, described water distribution
The water distribution in area adopts nonuniform mutation operator and subregion arrangement, takes one from inside to outside along the high-order diametric(al) receiving water cooling tower
Plant nonuniform mutation operator mode.
Described water distributing area partitioned mode is: centered on the vertical axis of cooling tower, is outwards divided into different radii successively
Three annular sections, i.e. a area, b area and c area.
The relation of the water distribution radius of described three water distributing areas is: a area≤b area≤c area.
The spray density relation of described three water distributing areas is: ＞ c area of ＞ b area of a area.
In the case of ensureing that total spray density amount is constant, the radius of the water distribution of described three water distributing areas are: a area
Water distribution radius: B area water distribution radius: C area water distribution radius: WhereinFor equivalent radius, for the ratio of water distributing area radius at this and water distribution zone radius maximum.
The spray density of described three water distributing areas is: a area: 1.05q≤wq≤1.15q；B area: 0.85q≤wq≤q；C area:
0.7q≤wq≤0.8q, wherein q are spray density during uniform water distribution.
Beneficial effects of the present invention are as follows:
Through catchment area after outside air entrance high-order receipts water cooling tower, because captation region is certain to air
Guide effect makes high-order water cooling tower central area air velocity of receiving maximum, outer peripheral areas air velocity minimum.Due to centre
Regional air flow velocity is maximum and zone line coolant water temperature cools down limit wet bulb air themperature apart from it and still has gap, i.e. mesozone
Domain cooling capacity also has room for promotion, under conditions of ensureing that water drenching gross density is constant, for utilizing its cooling capacity as far as possible, because
This increases zone line spray density, that is, allow central area to cool down more cooling waters.
Outer peripheral areas are not enough due to air mass flow, affect the cooling of its recirculated water, therefore for increasing its ventilation, improve cooling
Efficiency, under conditions of ensureing that water drenching gross density is constant, reduces outer peripheral areas spray density, that is, makes the cooling water of outer peripheral areas
Amount reduces, and increases its ventilation.

Specific embodiment
It is directed to the present invention to be described in more detail in conjunction with the embodiments.
A kind of high-order receipts non-homogeneous water distribution system of water cooling tower 1, including the water distributing area 2 in cooling tower, in water distributing area
Lower section be captation 3, the water distribution of water distributing area 2 adopts nonuniform mutation operator and subregion arrangement, receives water cooling tower along high-order
Diametric(al) take a kind of nonuniform mutation operator mode from inside to outside.Described water distributing area 2 partitioned mode is: perpendicular with cooling tower
To centered on axis, outwards it is divided into three annular sections of different radii successively, i.e. a area, b area and c area.
