Embodiment
By technology contents, the structural attitude of the present invention being described in detail, is realized object and effect, below in conjunction with enforcement mode and coordinate accompanying drawing to be explained in detail.
With reference to accompanying drawing 1, the present invention provides a kind of four-in-one water saving fog dispersal haze adverse currentcooling tower, comprise tower body 1 and wind power driving system, water-recovering device 2 it is disposed with in tower body, water saving fog dispersal haze heat exchanger 3 and upper spraying water system, described water-recovering device 2 is arranged on above water saving fog dispersal haze heat exchanger 3, described water saving fog dispersal haze interchanger 3 is plate-type heat exchanger, described plate-type heat exchanger comprises two adjacent passages, it is divided into clammy district 4 and dry and cold district 5, described clammy district and dry and cold district 5 are provided with water dispensing valve, described clammy district 4 does not communicate with dry and cold district 5, clammy district 4 and dry and cold district 5 carry out heat exchange by water saving fog dispersal haze heat exchanger thin-walled 6, described clammy district 4 is divided into upper part 7 and lower part 8(to have a definite limitation due to the height that described upward spraying type spray head sprays, so whole interchanger have spray less than place, as shown in Figure 3, more than dotted line for upper part be upward spraying type spray head injection less than place, for lower part is the place that upward spraying type spray head can be ejected into below dotted line), the upper part 7 in described clammy district 4 is gas gas (condensation) septate heat transfer, the lower part 8 in described clammy district 4 is air water septate heat transfer, water droplet in described clammy district and the water film being attached on thin-walled 6 constitute the surface of damp and hot cooling, described clammy district 4 and dry and cold district 5 export and produce saturated damp-heat air and heated dry air respectively, described upper spraying water system is made up of upper spray shower nozzle, and described upper spray shower nozzle is divided at least two regions.
In order to better realize the object of cooling, described wind power driving system comprises air duct 9, and described air duct 9 is arranged on above water-recovering device (air duct preferred form can be tall and big natural ventilation hyperbolic form). In order to better realize the object of cooling, being provided with blower fan 10(user inside described air duct 9 can select according to practical situation to need with blower fan).
Present invention heat exchanger thin-walled material preferably adopts PVC sheet, when water saving fog dispersal function is run, shower nozzle is to clammy district 4 Water-and mist-spraying, and the existing water droplet entering clammy district 4 has again air, droplets impact its turns into water film to thin-walled surface, and water film and water droplet provide the evaporation and heat-exchange surface in clammy district 4 jointly; Closing dry and cold district water dispensing valve, shower nozzle stops to dry and cold district 5 Water-and mist-spraying, enters the only cold dry air in dry and cold district 5, and by thin-walled and clammy district 4 heat exchange. During summer operation, opening dry and cold district 5 water dispensing valve, dry and cold district 5 also becomes clammy district 4, thus reduces energy consumption and the outlet water temperature of cooling tower to greatest extent, then can transform between the two in other seasons; Upper spray shower nozzle, is divided into two or some regions, by valve regulated water distribution area territory, thus reaches the object of adjustment current, and when cooling is main task, two passages have air-flow and current simultaneously, and this is the same with the operation of common cooling tower; When outside temperature reduces, when water saving fog dispersal haze is main task, turn off or close the water dispensing valve of little dry and cold district bottom shower nozzle, water saving fog dispersal haze heat exchanger is formed, there is current and the water droplet of damp-heat air and heat in clammy district 4, and there is the operation scheme of dry and cold air-flow in adjacent dry and cold district 5, and what carry out in dry and cold district 5 is empty cold, the cooling of this part thermal load does not need vaporize water, thus realizes the function of water saving; What carry out in bottom, clammy district is wet type cooling, what the outlet close to clammy district carried out is the condensation of damp-heat air, the water of condensation converges and returns in tower, what go out water saving fog dispersal haze heat exchanger has damp and hot and xeothermic two strands of air, after two kinds of air mixed, reduce air themperature and the water capacity of cooling tower outlet, thus achieve the fog dispersal function of cooling tower; Little droplets impact its, to heat exchanger surface, is converted into the water film of wet type cooling, and converges and flow back to downwards in tower, and essentially eliminating wafts drips, and this technology may be used for natural ventilation tower, machine power ventilation tower and secondary ventilation natural ventilation tower; Water distribution system can also just be set up on heat exchangers to increase its cooling efficiency, water-saving rate etc. in the basis of upper spray water distribution.
The foregoing is only embodiments of the invention; not thereby the patent scope of the present invention is limited; every utilize specification sheets of the present invention and accompanying drawing content to do equivalent structure or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all it is included in the scope of patent protection of the present invention with reason.
