Further, showerhead is arranged on the downside of the second end of shower.
Further, the second end of shower has two spaced showerheads.
Further, the interval between two showerheads is made as H2, wherein, and 0.5m≤H2≤3m.
According to smoke temperature reducer of the present utility model, this device comprises spray equipment, and spray equipment comprises at least one shower and at least one showerhead.The first end of shower connects water source, and the second end of shower stretches in flue device.Showerhead is arranged on the second end of shower, and an end of showerhead is connected with shower.Water with certain pressure enters shower, these water by showerhead, spray and atomization after the water smoke that forms and the high-temperature flue gas formation steam that flue device produces, high-temperature flue gas is played to the effect of cooling.This smoke temperature reducer cooling ability is strong, water consumption is low.
The accompanying drawing explanation
The accompanying drawing that forms the application's a part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the overall structure schematic diagram according to smoke temperature reducer of the present utility model.
The specific embodiment
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
Referring to Fig. 1, the utility model provides a kind of smoke temperature reducer.Smoke temperature reducer comprises spray equipment 10, and spray equipment 10 comprises at least one shower 11 and at least one showerhead 12.The first end of shower 11 connects water source, and the second end of shower 11 stretches in flue device 20.Showerhead 12 is arranged on the second end of shower 11, and an end of showerhead 12 is connected with shower 11.
This smoke temperature reducer comprises the spray equipment 10 with shower 11 and showerhead 12.The first end of shower 11 connects water source, and the second end of shower 11 stretches in flue device 20, and showerhead 12 is arranged on the second end of shower 11 and is interconnected.Water source provides the water of certain pressure, water with certain pressure enters in shower 11, the water that enters shower 11 sprays from shower 11 by showerhead 12 and atomization formation water smoke, the high-temperature flue gas that water smoke and flue device 20 produce forms steam, so just high-temperature flue gas is played the effect of cooling.Water smoke more can be fully than the cooling water droplet used of tradition and the high-temperature flue gas fusion, and cooling-down effect is better, and the water consumption of generation water smoke is less.This smoke temperature reducer cooling ability is strong, water consumption is low.
Have shower nozzle hole 14 on cannula portion 13, showerhead 12 stretches out shower nozzle hole 14.14 pairs, shower nozzle hole showerhead 12 plays the use of doing of directed and location.
Can arrange two showers 11 flue device 20 is interior, and two showers 11 arrange at interval in the upper and lower along the short transverse of flue device 20.Spaced advantage is, avoids because the water of 11 li ejections of shower intersects to form water droplet and affects cooling-down effect.The concrete quantity of shower 11 can be arranged according to on-the-spot actual environment.
The equal along continuous straight runs of the second end of two showers 11 extends, and two showers 11 are horizontally disposed.Interval between the second end of two showers 11 is made as H1, wherein, and 2m≤H1≤5m.The water smoke that general showerhead 12 sprays is solid taper, and the height of this solid-cone water smoke is about the 3m left and right.Producing water droplet for fear of solid-cone water smoke with intersecting of solid-cone water smoke affects cooling-down effect, so need spaced when arranging shower 11.Preferably, it is 3.5m that the interval between the second end of two showers 11 is made as H1, when guaranteeing cooling-down effect, has also taken into account the space that takes full advantage of flue device.
