Stagewise direct evaporative cooling system
This utility model is related to evaporative cooling system regions, relates in particular to stagewise direct evaporative cooling system
Evaporative Cooling Air Conditioning technology is a technology utilizing water evaporation absorption refrigeration.Water has evaporation energy in atmosphere
Power.Under conditions of not having other thermal source, the hot and humid area process between water and air is that sensible heat transfer is fed water by air, makes air
Temperature drop.And due to evaporation of water, the water capacity of air not only will increase, and the vapor of air inlet is taken back
The latent heat of vaporization.When both heats are equal, water temperature reaches the wet bulb temperature of air.As long as air is not saturation, using following
Ring water is direct（Or pass through packing layer）Spray air is achieved with the effect lowered the temperature.
Direct evaporating-cooling enables moistening and lowering temperature function, and it has, and economize on electricity, water saving, air flow resistance be little, structure is simple
Feature single, that one-time investment is little, is widely used in evaporating in cooling air processor group.
Spray pipe or Rectangular Water Trough water distribution shape as Chinese patent notification number discloses a kind of employing for CN203628887U
The direct evaporative cooler of formula, the cyclic water tank being arranged with filler bottom by direct evaporating-cooling filler, direct evaporating-cooling
Formed with the water-distributing device that filler top is arranged with direct evaporating-cooling, cyclic water tank passes through water distributor and water pump and water-distributing device
It is connected.There is structure simple, save energy consumption, reduce investment outlay and the advantages of water consumption, but this direct evaporative cooling system
System, its cooling filler is an entirety, and such situation can cause deposition on cooling filler because in During Process of Long-term Operation
Dust and block, need change when be then integral replacing.Simultaneously because cooling filler is a monolithic construction, wind is in front end
The necessary mix homogeneously in space, increases device length, causes waste of material.
Utility model content
For the problems referred to above, this utility model provides a kind of stagewise direct evaporative cooling system, to solve existing skill
Problem in art.
To achieve these goals, this utility model provides one kind：
, it is characterised in that including air duct, in described air duct, edge is empty for stagewise direct evaporative cooling system
Fate line direction has been arranged side by side at least two sections direct evaporating-cooling fillers, arranges below described direct evaporating-cooling filler
There is water tank, the top of described direct evaporating-cooling filler is provided with spray equipment.
In preferred embodiment of the present utility model, described spray equipment include spray head, water circulating pump, water route pipe fitting and
Control valve；Water tank passes through water route pipe fitting and the import of water circulating pump connects, and water route pipe fitting and control are passed through in the outlet of water circulating pump
Valve is connected with spray head.
In preferred embodiment of the present utility model, between described adjacent segment direct evaporating-cooling filler interval one section away from
In preferred embodiment of the present utility model, described control valve is electromagnetic valve.
In a preferred embodiment of the invention, direct evaporating-cooling filler has two sections, by distinguished and admirable to described leading portion is straight
The thickness connecing evaporation cooling filler is less than the thickness of back segment direct evaporating-cooling filler.Further, described back segment directly steams
Feel cold be but leading portion direct evaporating-cooling filler with the thickness of filler 1.5-3 times.
This utility model using by direct evaporating-cooling with the technical solution of filler segmentation so that direct evaporating-cooling
When needing to change because depositing dust with filler, only need to change leading portion direct evaporating-cooling filler, reduce replacement cost.Simultaneously by
In two-part arrangement so that wind is remixing entrance back segment direct evaporating-cooling use after leading portion direct evaporating-cooling filler
Filler so that air evenly, water evaporation is got volume system and is in evaporating completely state all the time, greatly improve sweat cooling effect
Feature of the present utility model see the detailed description of this case schema and following preferable embodiment and obtains clear
Fig. 1 is the schematic diagram of this utility model embodiment 1.
Fig. 2 is the air handling process figure of direct evaporative cooling.
Fig. 3 is the schematic diagram of this utility model embodiment 2.
In order that technological means, creation characteristic, reached purpose and effect that this utility model is realized are easy to understand, under
Face is expanded on further this utility model in conjunction with specific embodiments.
Referring to Fig. 1-2, stagewise direct evaporative cooling system, including air duct, transport along air in the air passageway
Line direction has been arranged side by side two sections of direct evaporating-cooling fillers, and respectively leading portion direct evaporating-cooling is straight with filler 4 and back segment
Connect evaporation cooling filler 8, the thickness of leading portion direct evaporating-cooling filler is less than the thickness of back segment direct evaporating-cooling filler
Degree.In the present embodiment, the thickness of back segment direct evaporating-cooling filler is the 1.5-3 of leading portion direct evaporating-cooling filler
Times.It is spaced a distance between front and rear sections direct evaporating-cooling filler.
It is provided with water tank 2 below direct evaporating-cooling filler, the top of direct evaporating-cooling filler is provided with spray
Spray equipment includes spray head 7, water circulating pump 3, water route pipe fitting and electromagnetic valve 6；Water tank 2 passes through water route pipe fitting and follows
The import of ring water pump connects, and water route pipe fitting is passed through in the outlet of water circulating pump 3 and electromagnetic valve 6 is connected with spray head 7.
After outdoor fresh air or other wind 5 of processing enter stagewise direct evaporative cooling system, first pass through leading portion straight
Connect evaporation cooling filler 4, the water evaporation heat absorption being sprayed by spray head 7, so that dry air increases humidity for the first time and lowers the temperature, obtains
It is the J1 in Fig. 2 to air condition.Subsequently into back segment direct evaporating-cooling filler 8, in back segment direct evaporating-cooling with filling out
Contact evaporation endothermic and increase humidity with the water that spray head gushes out again in material 8, and reduce temperature, obtaining air condition is
S1 in Fig. 2, completes direct evaporation temperature-fall period.And be above that the clean dust of filtration is agglomerating because humidity increases, most of stream
In the leading portion direct evaporating-cooling inside of filler 4, after down arrive water tank precipitation with current, it is direct that fraction has stayed leading portion
