Description

A kind of rear-mounted spraying humidification blower fan
Technical field
The utility model belongs to the air conditioner refrigerating technical field, relates to a kind of spraying humidification device, is specifically related to a kind of rear-mounted spraying humidification blower fan.
Background technology
At present, regulating the air-humidification method that air adopted mainly contains: 1) spray chamber humidification system, 2) the spray axial fan humidification system.The spray chamber humidification system can be realized multiple air handling process, has certain ability that purifies air, but the wet exchange of the heat of this system is only carried out between spray comb and water fender, distance is short, and resistance is big, and energy consumption is higher, initial outlay is big, and the regular maintenance management workload is heavy.The spray axial fan humidification system is that water is delivered on the blower fan, water just contacts at the blower fan end with distinguished and admirable, and can last till whole air channel course of conveying, time of contact is long, the droplet that produces is fine, greatly improve the contact area with air, had higher efficiency of damp and hot exchanging, water-saving, power saving to a certain extent, reduced initial outlay.But there is following problem in this spray axial fan: only depend on the blade rotation cutting of blower fan, make water atomization, steam is higher, drainage is serious; Air-flow mixes at the impeller place of mist-spraying cooling fan with current, forms gas-liquid two-phase and flows, and a large amount of droplets has increased the viscous drag of air stream, causes blower fan to reduce than the air quantity under the conventional ventilation state, and blast reduces, and fan efficiency descends.
Summary of the invention
The purpose of this utility model provides a kind of rear-mounted spraying humidification blower fan, utilizes secondary-atomizing, adverse current incision principle, further improves the fogging degree of water, reduces steam, stops drainage, improves air output, blast and the fan efficiency of blower fan.
The technical scheme that the utility model adopted is, rear-mounted spraying humidification blower fan, comprise air duct, in the air duct, the water fender that is disposed with motor, is provided with by motor-driven impeller and air duct air outlet place by the air intake direction, in the air duct, also be provided with sprayer unit between impeller and the water fender, sprayer unit comprises an annular spray pipe, sparge pipe is connected by the high-pressure hydraulic pump of water inlet pipe with the air duct outside, be evenly equipped with a plurality of nozzles on the circumference of annular spray pipe, nozzle communicate with sparge pipe and its injection direction towards impeller.
Characteristics of the present utility model also are,
Inwall by a plurality of pull bars and air duct on the circumference of sparge pipe fixes.
The bottom of water fender is provided with return pipe.
The axle center of motor and the axle center of air duct coincide.
The utlity model has following advantage:
1. the wet exchange of heat is not only carried out between spray comb and water fender, and interacts with high wind that blower fan produces, mixes repeatedly atomizing repeatedly, efficiency of damp and hot exchanging height;
2. utilization adverse current incision principle carries out secondary-atomizing to water, rather than only depends on the blade rotation cutting of blower fan to make water atomization, and WGR is lower, avoided drainage.
3. changed mist-spraying cooling fan impeller place's air-flow and current hybrid mode, formed the gas-liquid mixed vaporific air stream of high humidity comparatively fully, overcome blower fan, improved fan efficiency than problems such as air quantity minimizing under the conventional ventilation state, blast reductions.
4. the technology that adopts air-supply and air-conditioner humidifying to organically combine has proposed a kind of existing ripe air-foil fan that both utilized, and the high-effect rear-mounted spraying humidification blower fan of essential distinction is arranged with traditional air conditioning mode again.Has higher efficiency of damp and hot exchanging than traditional spray chamber and spraying humidification blower fan, water saving, economize on electricity, energy-conservation.
5. when the cooling air is provided for building, can provide the air of humidification again, carry out air wetting quickly and easily.Low input, low operating cost ground are realized humidification, cooling, are improved working environment.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model spraying humidification blower fan; Wherein, a is a front view, and b is a left view.
Among the figure, 1. motor, 2. impeller, 3. water inlet pipe, 4. sparge pipe, 5. nozzle, 6. pull bar, 7. water fender, 8. air duct, 9. electric machine support, 10. return pipe.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Spraying humidification blower fan of the present utility model as shown in Figure 1, in the air duct 8, is disposed with by the air intake direction: motor 1, support by electric machine support 9, and guarantee the axle center of motor 1 and the axis coinciding of air duct 8; The impeller 2 of fixedlying connected with motor shaft is driven by motor 1; The water fender 7 that the air outlet place of air duct 8 is provided with, the bottom of water fender 7 is provided with return pipe 10; In the air duct 8, be provided with sprayer unit between water fender 7 and the impeller 2, sprayer unit is an annular spray pipe 4, this annular spray pipe 4 is fixed on the inwall of air duct 8 by pull bar 6, sparge pipe 4 is connected with an end of water inlet pipe 3, and the other end of water inlet pipe 3 stretches out from the top of air duct 8 and is connected with high-pressure hydraulic pump, uniform a plurality of nozzles 5 on the circumference of sparge pipe 4, nozzle 5 communicates with sparge pipe 4, and it ejects mouth of a river direction towards impeller 2.
The course of work of the present utility model:
Motor 1 is connected power supply, and the motor shaft of motor 1 begins rotation at a high speed, drives the impeller 2 that is fixed on motor shaft high speed rotating together simultaneously.At a high speed the impeller 2 of rotation blows to the air outlet of air duct 8 with air, and at this moment, the back of impeller 2 forms vacuum, and air air inlet from air duct 8 under action of pressure enters air duct 8, air duct 8 in formation by air inlet to the air outlet airflow flowing.Open high-pressure hydraulic pump, water forms the water under high pressure with pressure after pressurizeing by high-pressure hydraulic pump, and water under high pressure enters annular spray pipe 4 by water inlet pipe 3, enters nozzle 5 then.Water under high pressure in the sparge pipe 4 is along the circulating line flow at high speed, produce centrifugal force, the water of this centrifugal action in entering nozzle 5 makes water be stretched to film on its surface, and, spray at a high speed from nozzle 5 delivery ports at last with of the outlet campaign of ever-increasing speed to nozzle 5.
The water of the delivery port ejection by nozzle 5, upwind sprays to impeller 2, realizes atomizing for the first time; Impeller 2 produces the lift effect in the high speed rotary course, under the high wind effect, the little water droplet that is not atomized further forms " water curtain ", realizes atomizing for the second time." water curtain " interacts with high wind, mixes repeatedly atomizing repeatedly, and the fine water droplets after the atomizing is mixed the vaporific air stream of formation high humidity, the air outlet of this air flow air duct 8 with air-flow.Motor 1 impeller 2 constantly turns round, and nozzle 5 constantly provides water smoke, realizes and finished the overall process of carrying air and handling air.
The water that part is not atomized runs into water fender 7, on the sidewall attached to water fender 7 with the exit of air-flow arrival air duct 8.Then, flow downward, enter the return pipe 10 that water fender 7 bottoms are provided with, and it is recycling to flow back to feed cistern by return pipe 10 at the sidewall of gravity effect lower edge water fender 7.
