Description
Technical field
The utility model relates to a kind of nozzle, is specifically related to a kind of rotary-cut stream nozzle.
Background technology
In China, the development of acid rain serious harm national economy and the heavy damage ecological balance, along with the raising of people's environmental consciousness, the implementing and implementing of environmental protection policy, environmental protection equipment is about to become an important pillar industry.Wet Flue Gas Desulfurization Technology is present scope of application method the most widely, accounts for more than 80% of desulfurization facility total amount, and it has, and desulfuration efficiency is high, absorbent utilization rate advantages of higher, and existing various desulphurization plants are all to make according to this principle.The nozzle of the designs such as existing spray column, turbulent tower is to contact with gas phase with liquid pearl form, and its contact area is less, and adopts static liquid film to contact with gas phase in packed tower, rotating stream tray scrubber, and its contact area is also less, and assimilation effect is all very poor.The technology that washer adopts liquid phase and gas phase to contact along spray or contrary spray can't produce effectively interception to flue dust, the mist material that produces.Above various device all exists desulfuration efficiency low, the shortcoming of weak effect.
The utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of rotary-cut stream nozzle, has mainly solved existing wet scrubbing apparatus desulfuration efficiency low, the problem of weak effect.
The technical scheme that the utility model adopts is: a kind of rotary-cut stream nozzle, comprise housing, be provided with the cavity of truncated cone-shaped in described housing, the larger end of described cavity is inlet, be liquid outlet than small end, be provided with the nozzle core in described cavity, described nozzle core end face be provided with some centered by the nozzle mandrel heart eddy current hole of circumference uniform distribution, the all sides of described nozzle core evenly are provided with the eddy flow groove of some inclinations, also be provided with the diffusion part in described shell, described diffusion part one end is horn-like, and a described horn-like end extends liquid outlet.
Described eddy current hole is cylindrical for what tilt.
Described nozzle core is round pie.
Described liquid outlet is horn-like.
Described inlet end face is provided with flange face.
Described diffusion part is fixed on flange face by nut.
The beneficial effects of the utility model are: make the washing lotion that nozzle gushes out be continuously dynamic moisture film shape, increase the contact area of liquid phase, reach the exchange of matter and energy, with the momentum consumption of minimum, reach maximum clean result.Utilize the thin and multilayer of liquid film, characteristics that resistance is little, extended the time of contact of gas, liquid, stop to have absorbed dust, complete efficient absorption and heat transfer, mass transport process.Improve operating efficiency and the working effect of wet scrubbing.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
as Fig. 1 in conjunction with as shown in Fig. 2 to 4, a kind of rotary-cut stream nozzle, comprise housing 1, be provided with the cavity 2 of truncated cone-shaped in described housing 1, the larger end of described cavity 2 is inlet 21, be liquid outlet 22 than small end, be provided with nozzle core 3 in described cavity 2, described nozzle core 3 end faces be provided with some centered by the nozzle mandrel heart eddy current hole 31 of circumference uniform distribution, the all sides of described nozzle core 3 evenly are provided with the eddy flow groove 32 of some inclinations, also be provided with diffusion part 4 in described shell 1, described diffusion part 4 one ends are horn-like, and a described horn-like end extends liquid outlet 22.Make the washing lotion that nozzle gushes out be continuously dynamic moisture film shape, increase the contact area of liquid phase, reach the exchange of matter and energy, with the momentum consumption of minimum, reach maximum clean result.
Described eddy current hole 31 is cylindrical for what tilt.
Described nozzle core 3 is round pie, is conducive to washing lotion and forms eddy current in housing.
Described liquid outlet 22 is horn-like, is conducive to washing lotion and forms continuously dynamic moisture film.
Described inlet 21 end faces are provided with flange face 5, and nozzle is fixed on water pipe, are connected firmly.
Described diffusion part 4 is fixed on flange face 5 by nut, guarantees the distance of diffusion part 4 and liquid outlet 22.
The concrete use of the utility model is as follows: during work, current flow into housings 1 from inlet 21, and during through the eddy current hole 31 on nozzle core 3 and eddy flow groove 32, current form eddy current and scatter equably.When ejection liquid outlet 22 entered reaction tube, the effect due to diffusion part 4 diffuseed to form horizontal moisture film.A plurality of described nozzles produce the moisture film of multiple-layer horizontal direction, make gas and liquid be 90 degree angles.Described gas is sheared by the liquid at high speed layering, thereby increases medium mass transfer, heat transfer area; Simultaneously because flue dust, droplet can be effectively removed in the interception of moisture film.Liquid also can with reaction tube tube wall collision, change shearing force and the surface tension of liquid, cause that the interface upgrades and inner circulation, quickening is to the absorption of gas and gas piece speed is contacted with liquid surface circularly, completes efficient absorption and heat transfer, mass transport process.
The beneficial effect of utility model is: make the washing lotion that nozzle gushes out be continuously dynamic moisture film shape, increase the contact area of liquid phase, reach the exchange of matter and energy, with the momentum consumption of minimum, reach maximum clean result.Utilize the thin and multilayer of moisture film, characteristics that resistance is little, extended the time of contact of gas, liquid, stop to have absorbed dust, complete efficient absorption and heat transfer, mass transport process.Improve operating efficiency and the working effect of wet scrubbing.
