Description
[technical field]
The utility model relates to a kind of nozzle, especially relates to a kind of two-sided injection nozzle being applicable to gas cleaning process or flue gas and cooling.
[background technology]
Along with the requirement of country to environmental protection is more and more higher, after the flue gas that the large size industrial enterprises such as all kinds of chemical plant, oil plant, steel plant produce all needs to be purified by desulfuring and denitrifying apparatus, then be discharged in air.Desulfuring and denitrifying apparatus generally has scrubbing tower, is provided with Washing spray nozzle in scrubbing tower, and alkali lye, by being atomized after Washing spray nozzle, forms the alkali mist of special shape in scrubbing tower, and alkali mist and flue gas hybrid reaction, reach the effect of desulfurization and dedusting.After the liquid directive scrubbing tower tower wall that nozzle sprays in addition, form liquid film, high-temperature flue gas and scrubbing tower backing layer are separated, play the effect of protection scrubbing tower backing layer.
Also various forms of nozzle is had in prior art, but the liquid of most of nozzle ejection is the one side mist torch of conical hollow, the contact of liquid and gas is insufficient, there is the phenomenon of flue gas short circuit, therefore need to operate according to larger liquid-gas ratio, to ensure that flue gas can fully purify, the energy consumption of pump will be increased like this; One side taper mist torch also makes the hybrid reaction of flue gas and alkali mist apart from long, adds the height of equipment, equipment investment is increased; Spray cone makes the stroke of drop in scrubbing tower long in addition, and kinetic energy decay is fast, is difficult to form liquid film protection to scrubbing tower backing layer, reduces the service life of scrubbing tower backing layer.
[utility model content]
In order to overcome the deficiency in background technology, the utility model discloses a kind of two-sided injection nozzle, reaching the object enabling the fully reaction in shorter distance of flue gas and alkali mist.
In order to realize described goal of the invention, the utility model adopts following technical scheme:
A kind of two-sided injection nozzle, its structure is primarily of feed tube, special-shaped adapter, current divider, external annulus, internal ring wall, the outlet conical surface, central dividing plate forms, the entrance of special-shaped adapter is circular, outlet is rectangle, current divider has two guiding gutters, the runner of guiding gutter is streamlined, the pressure loss of liquid can be reduced so as much as possible, to reduce pump pressure, reduce energy consumption, external annulus, internal ring wall, central dividing plate and the outlet conical surface form two non-interfering spin chambers, guiding gutter is communicated with Liang Ge spin chamber, according to actual needs, the size of two guiding gutters can be different, so just can the flow of control Liang Ge spin chamber respectively, the physical dimension of Liang Ge spin chamber also can be different, so just can control separately the shape of each side spray, the optimum range of the spray angle α of eddy flow chamber 1 and eddy flow chamber 5 spout is 50 ° ~ 170 °, and the optimum range of β is 50 ° ~ 170 °.
Owing to have employed technique scheme, the utility model has following beneficial effect:
1, structure is simple, reliable, and anti-blockage capability is strong, wear-resistant, can meet the rigors of industry park plan;
2, make full use of fluid pressure atomization, adopt low pressure drop runner design, be conducive to energy-conservation;
3, operating pressure is low, and the degree of wear is light, is conducive to improving service life;
4, the mist flow of nozzle both sides can be different, by optimizing the assignment of traffic of levels, can reduce liquid consumption to greatest extent, reducing costs;
5, the spray angle of nozzle both sides can be different, to improve droplet degree of scatter in a reservoir.

[detailed description of the invention]
By explanation the utility model that the following examples can be detailed, open the purpose of this utility model is intended to protect all technological improvements within the scope of the utility model.
Two-sided injection nozzle by reference to the accompanying drawings described in 1-7, comprises feed tube 4, special-shaped adapter 3, current divider 2, external annulus 11, internal ring wall 13, the outlet conical surface 12, central dividing plate 14.The entrance of special-shaped adapter 3 is circular, and export as rectangle, current divider 2 has two guiding gutters 21, the runner of guiding gutter is streamlined.External annulus 11, internal ring wall 13, central dividing plate 14 and the outlet conical surface 12 form two non-interfering spin chambers 1 and spin chamber 5.According to actual needs, the size of two guiding gutters 21 can be different, so just can control the flow of respective spin chamber respectively; The physical dimension of spin chamber 1 and spin chamber 5 also can be different, so just can control separately the angle of each side spray.
Implement two-sided injection nozzle described in the utility model, operationally, liquid flows into special-shaped adapter 3 from feed tube 4, after abnormal shape adapter 3 rectification, flow into current divider 2, current divider 2 has two guiding gutters 21, respectively liquid is imported two mutual disconnected eddy flow chambeies 1 and eddy flow chamber 5, liquid accelerates to rotate in eddy flow chamber 1 and eddy flow chamber 5, under the influence of centrifugal force, spray respectively from the spout in eddy flow chamber 1 and eddy flow chamber 5, then after the rectification of the outlet conical surface 12, form non-interfering two-sided droplet group.In order to obtain better droplet group distribution, the central axis in two eddy flow chambeies can not overlap.
The non-detailed portion of the utility model is prior art.
In order to open utility model object of the present utility model and the embodiment selected in this article, currently think to be suitable for, but it is to be understood that the utility model is intended to comprise all changes belonging to the embodiment within the scope of this design and utility model and improvement.
