Specific embodiment
Below in conjunction with attached drawing, detailed description of the preferred embodiments.It should be understood that this place is retouched
The specific embodiment stated is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
As shown in Figures 1 to 6, a kind of labyrinth damp type condensation fog-dissipation water collector of the present embodiment, including two groups opposite
Labyrinth type dividing wall type heat exchanger 5 and the V-shape cold dry air of middle section converge area 6.
Labyrinth type dividing wall type heat exchanger is by successively 502 structure of alternately arranged labyrinth type cold passage 501 and the labyrinth type passage of heat
Be at, the gas flow in labyrinth type cold passage 501 it is horizontally disposed, the gas flow in the labyrinth type passage of heat 502 is vertically to set
It sets；Cold dry air horizontally enters into labyrinth type cold passage 501 from two sides, and damp-heat air is logical vertically into labyrinth type heat from the bottom to top
In road 502, hot and cold air carries out heat exchange in labyrinth type dividing wall type heat exchanger 5, and cold dry air enters dry and cold sky after heat exchange
Gas converges area 6.Since V-shape cold dry air converges the setting in area 6, can make after heat exchange cold dry air have one obliquely
Component velocity, conducive to the mixing of hot and cold air after heat exchange.
Above-mentioned labyrinth type cold passage 501 and the labyrinth type passage of heat 502 are referred to as heat exchanger channels, and heat exchanger channels are by two pieces of phases
Pair heat exchanger plates 11 constitute, heat exchanger plates 11 be labyrinth shape；It is logical that the peak valley of every two pieces of heat exchanger plates 11 contrasts one labyrinth type of composition
Road, labyrinth type channel form periodic dilation and contraction.
In the present embodiment, two pieces of heat exchanger plates 11 of every composition heat exchanger channels use the combining form of mirror image corresponding form.
Heat exchanger plates 11 are surrounded by sealing plate and are sealed to cold and hot channel, and downside is close on it for labyrinth type cold passage 501
Envelope closing, the labyrinth type passage of heat 502 are closed in its left and right side seal, and every two with respect to setting respectively on the sealing plate of heat exchanger plates
The seal convexity 504 and sealed groove 505 for having several to be mutually matched are for sealing.
Two pieces of heat exchanger plates middle sections of every group of composition heat exchanger channels are disposed with raised butt joint 503, two pieces of heat exchanger plates 11
The bonding of butt joint 503 can play a supporting role to channel and prevent channel from collapsing.
The crest height of heat exchanger plates 11 is that will not make again when playing the role of enhancing and reinforcing air agitation cold without height is detained
Air generates delay, and 11 material of heat exchanger plates uses high thermal conductivity coefficient light material, exchanges heat conducive to hot and cold air.Position simultaneously
It is coated with hydrophilic material coating in 11 surface of heat exchanger plates of labyrinth type passage of heat two sides, is caught conducive to damp-heat air condensed water
Collection.
Flow area constantly changes and can increase cold air and disturb cold air during bottom horizontal flow sheet in labyrinth type cold passage 501
The dynamic coefficient of heat transfer that increases plays the role of the resistance balance that balancing resistance promotes damp and hot air-flow and cold airflow simultaneously, prevents cold air stream
The generation of short circuit phenomenon is measured, and channel is that labyrinth type can also extend air flow increase heat-exchange time.
Labyrinth damp type condensation fog-dissipation water collector of the invention is applied in cooling tower, if Fig. 2 is the embodiment of the present invention
Schematic view of the mounting position in cooling tower.
The cooling tower course of work is as follows: high temperature circulation cooling water is sprayed on filler 2 by high temperature circulation water by water injector 3
Enter cold air progress caloic with the 1 lower part air inlet of tower body from cooling tower to exchange, circulating cooling coolant-temperature gage reduces；By caloic
The air temperature entered below cooling tower after exchange rises, and water capacity increases, and forms the damp-heat air being substantially saturated；It is damp and hot
Wandering water is captured when air is by water collection device 4, continues to ascend into labyrinth type condensation receipts water fog-dissipation device of the present invention later
It is cold logical with labyrinth type in labyrinth type condensation receipts water fog-dissipation device of the present invention is entered from cooling tower two sides in the labyrinth type passage of heat 502
The cold dry air in road 501 exchanges heat；Damp-heat air cools down condensation in the passage of heat, and condensed water is by passage of heat surface hydrophilicity
Coating trapping, cold dry air temperature increase, and two sides cold air condenses V-shape among receipts water fog-dissipation device in labyrinth type of the present invention and does
Cold air converges area 6 and converges rising, mixes in mixing section gas chamber 10 with by the hot-air of the labyrinth type passage of heat 502, mixes
When air is by the heater 7 that is arranged in mixing section gas chamber 10, it can be heated, atmosphere is finally being expelled to by blower 9.
Embodiment two:
As shown in fig. 7, the present embodiment and embodiment one the difference is that: two pieces of every group of composition labyrinth type cold passage 501
