Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, the present invention is described further:
Embodiment one:
Centrifugal air blast crossing current closed cooling tower as shown in Figure 1, including tower body 1, cfentrifugal blower 2, water collection device
3 and the water-distributing device 4 and heat exchange coil 5, water collection device 3 and the cfentrifugal blower 2 that are fixed on from top to bottom in tower body 1 set up separately
In heat exchange coil 5 both sides, tower body 1 has side-entrance, the air outlet of cfentrifugal blower 2 near the side of cfentrifugal blower 2
Connect with side-entrance；Tower body 1 has side outlet near the outer wall of water collection device 3, and this side outlet is positioned at the tower body 1 of water collection device 3 correspondence
On sidewall, water collection device 3 is located at the interior also sealing cover of tower body 1 in side outlet；Water-distributing device 4 has multiple shower nozzles 41 of spray hot water, should
Shower nozzle 41 is located at above heat exchange coil 5, and and filler device between formed spray district；Have for cooling down heat in heat exchange coil 5
The cooling medium of water.
During use, the shower nozzle 41 of water-distributing device 4 sprays hot water towards heat exchange coil 5, and hot water stays along heat exchange coil 5 surface,
And moisture film is formed on its surface, and the cooling medium in heat exchange coil 5 can carry out indirect thermal friendship by heat exchange coil 5 and hot water
Change；Meanwhile, cold dry air can be taken out by the cfentrifugal blower 2 being positioned at heat exchange coil 5 side along the side-entrance of tower body 1 side
Entering in tower body 1, owing to being provided with side outlet on the tower body 1 corresponding at the opposite side of heat exchange coil 5, and sealing cover has on this side outlet
Water collection device 3, therefore, cold dry air enters after tower body 1, can first pass through heat exchange coil 5 and with moisture film generation heat exchange thereon, and
Again lowering the temperature hot water, and cold dry air becomes damp-heat air after lowering the temperature moisture film, this damp-heat air can carry greatly
The water of partial warm down enters water collection device 3, and after water collection device 3 is to its moisture absorption, damp-heat air becomes heated dry air by water collection device 3
The side outlet of the sidewall of corresponding tower body 1 is discharged.During Gai, owing to side-entrance and side outlet are divided into tower body 1 both sides,
Therefore, under the effect of cfentrifugal blower 2, the air entering tower body 1 can be with horizontal mobility, and by tower body after heat exchange coil 5
The side outlet of 1 sidewall flows out, therefore this centrifugal air blast crossing current open cooling tower can apply to similar ventilation shaft, melt pit it
The occasion needing side air-out of class.
In order to the hot water sprayed by shower nozzle 41 is fully lowered the temperature, as a kind of preferred version, in the present embodiment also
Being additionally arranged one in tower body 1 and will spray the water fender 6 that district encloses, the hot water that shower nozzle 41 can be sprayed by this water fender 6 is formed
Enclose guiding, make the hot water sprayed can fall on heat exchange coil 5, so that hot water and heat exchange coil 5 and the heat of cold dry air
Exchange is fully.
In order to realize the frequent maintenance in tower body 1, the present embodiment is also additionally arranged maintenance door 7 at tower body 1 outer wall.This
Outward, in order to cost-effective, the cooling medium in the heat exchange coil 5 of the present embodiment is water, and water pumps into heat exchange coil 5 for convenience
In, also it is additionally arranged water circulating pump 8, and is additionally arranged at the bottom of water intaking valve 11 and outlet valve 12, wherein, entering of water circulating pump 8 at tower body 1
The mouth of a river connects with water intaking valve 11, and one end of heat exchange coil 5 connects with the water inlet of water circulating pump 8, and water collection device 3 and heat exchange coil
The other end of 5 all connects with outlet valve 12, such that it is able to the cooling water that the water in heat exchange coil 5 and water collection device 3 are collected
Drawn by outlet valve 12.And in order to prevent water collection device 3 full water from overflowing, make tower body 1 internal water accumulation too much, also at tower body in the present embodiment
It is additionally arranged level switch in 1, and has been additionally arranged at the bottom of full water valve 13 at tower body 1, and make level switch be electrically connected with full water valve 13
Connect, in order to when tower body 1 internal water accumulation is too much, in time hydrops can be discharged by full water valve 13.And when needing in tower body 1
When portion is carried out, for the ease of being discharged by the dirt in tower body 1, the present embodiment is also additionally arranged at the bottom of blowoff valve at tower body 1
14.Further, clean and maintenance heat exchange coil 5 for convenience, the present embodiment is also additionally arranged in tower body 1 fixed mount, and changes
Hot coil 5 is removably fixed thereon, therefore, and this heat exchange coil 5 not only simple installation, and be easy to unpick and wash.
In order to improve heat transfer effect, as a kind of preferred version, as in figure 2 it is shown, the heat exchange coil 5 in the present embodiment is spiral shell
Capstan pipe, this spiral coil can increase heat exchange area, thus improve heat transfer effect.Further, heat exchange coil 5 can also use
Heat-conducting effect significant dephosphorization copper tube is made, naturally it is also possible to use other materials to make.
Embodiment two:
As it is shown on figure 3, embodiment two is from the different places of embodiment one, in water collection device 3 correspondence in embodiment one
Tower body 1 outer wall is provided with side outlet, and this side outlet is located on tower body 1 sidewall, and in the present embodiment in water collection device 3 correspondence
Tower body 1 outer wall is provided with and ejects mouth, and this ejects mouth and is located at tower body 1 top.So, the side-entrance from heat exchange coil 5 side enters
The air of tower body 1, after flowing through heat exchange coil 5, can eject mouth from heat exchange coil 5 opposite side and flow out, thus be possible not only to heat
Water for cooling, and centrifugal air blast crossing current open cooling tower can be made to can apply to the need of similar ventilation shaft, melt pit etc
Want the occasion of side air-out.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various
Corresponding change and deformation, and all these change and deformation all should belong to the protection domain of the claims in the present invention
Within.
