Description
Technical field
The utility model relates to a kind of nozzles, especially disclose a kind of through type with rifling applied in desulphurization system
Nozzle, in the liquid column tower applied to heat-engine plant wet flue gas desulphurization system.
Background technique
Heat-engine plant wet desulfurization absorption of technology tower mainly has spray column, liquid column tower and bubble tower several at present.Bubble tower
Middle no slurry nozzle, is arranged slurry nozzle in spray column and liquid column tower, and spray column is in order to have preferably covering and an atomizing effect, and one
As use spiral nozzle.Liquid column tower is at present generally using straight-through nozzle, and nozzle is straight pipe, and nozzle is set to guniting pipe of liquid column tower
On, slurries are sprayed from the bottom to top by nozzle, form slurries fluid column, and slurries are deviate from the process for rising and falling after rise with smoke contacts
SO2 in flue gas, due to liquid column tower generally only be arranged one layer of nozzle, so for nozzle spray slurries fluid column verticality with
And coverage rate has strict requirements, the slurries liquid-column height and verticality and single-nozzle that common straight-through nozzle sprays
Coverage rate, deviation and deviation can be generated when slurries amount has fluctuation or due to abrasion of nozzle itself etc. so that spray
Slurries fluid column out generates skew, and the coverage rate of design may be not achieved in slurries, or even will form smoke corridor, reduces desulfurization effect
Rate.
In the case where environmental protection increasingly requires stringent overall situation, desulphurization system will be run simultaneously with boiler, to desulfuration efficiency
The monitoring of high request and continuous-stable is also increasingly stringenter, so efficient and stable nozzle and whitewashing form are especially heavy
Want, if because nozzle it is unstable cause desulphurization system fluctuate or desulfuration efficiency decline, will cause environmental pollution or because
Blowing out generates massive losses.
Summary of the invention
Utility model aims to solve the defects of the prior art, provide a kind of band thorax applied in desulphurization system
The through type nozzle of line, the slurries fluid column sprayed have very high linearity and stability, will not be because of the wave of slurry flow
Dynamic or nozzle abrasion causes the deviation and deviation of slurries fluid column, ensure that the coverage rate of slurries and the uniformity of slurries covering,
Improve desulfurization stability and desulfuration efficiency.
The utility model is realized in this way: a kind of through type nozzle with rifling applied in desulphurization system, it is special
Sign is: the through type nozzle includes nozzle body and the slurry flow channel being arranged in nozzle body, the slurry stream
Circulation passage includes connected horn mouth and straight tube, and the inner wall of the straight tube is equipped with several riflings, the nozzle body and spray
Starch pipe connection.
Flanged joint or bonding is used between the nozzle body and shotcrete pipe, the height of the nozzle body is 50-
500mm, the nozzle body are one of silicon carbide nozzle, ceramic nozzle, glass reinforced plastic nozzle or alloy nozzle.
The quantity of several riflings is 2-8 item, rifling from the inlet of the straight tube in the slurry flow channel or in
Portion starts to open up always to the exit of straight tube, and diameter is 50-120mm, institute at the horn inlet in the slurry flow channel
The diameter for stating the straight tube in slurry flow channel is 35-50mm.
The beneficial effects of the utility model are: the utility model sprays slurries from lower to upper, the slurries of ejection are micro- rotation
The slurries fluid column turned, is not atomized, and slurries are constantly hit with the slurries of whereabouts during spraying from lower to upper, forms slurries and disturbs
Dynamic layer, forms water curtain, the SO in washing flue gas2Meanwhile also having good washing effect to the dust in flue gas, it mentions significantly
High efficiency of dust collection, and it is not necessarily to atomizing pressure, it is possible to reduce the lift of circulating pump is saved energy consumption, and is led to desulfurization fume
Stream effect, nozzle and shotcrete pipe maintenance replacement are convenient.The slurries that the utility model sprays form micro- rotation under the action of rifling
Slurries fluid column, spray slurries fluid column have very high linearity and stability, will not because of slurry flow fluctuation or
The abrasion of nozzle causes the deviation and deviation of slurries fluid column, ensure that the coverage rate of slurries and the uniformity of slurries covering, improves
Desulfurization stability and desulfuration efficiency.
Detailed description of the invention
Fig. 1 is schematic cross-sectional view when using flanged joint between the utility model and shotcrete pipe.
Fig. 2 is structure schematic diagram when using Nian Jie between the utility model and shotcrete pipe.
In figure: 1, nozzle body；2, horn mouth；3, straight tube；4, rifling；5, flange.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
With reference to the accompanying drawings 1 and attached drawing 2, the utility model is a kind of through type spray with rifling applied in desulphurization system
Mouth, including nozzle body 1 and the slurry flow channel being arranged in nozzle body 1, the slurry flow channel includes connected
The inner wall of horn mouth 2 and straight tube 3, the straight tube 3 is equipped with several riflings 4, and the nozzle body 1 is connect with shotcrete pipe.
The connection or Nian Jie of flange 5 is used between the nozzle body 1 and shotcrete pipe, the height of the nozzle body 1 is 50-
500mm, the nozzle body 1 are one of silicon carbide nozzle, ceramic nozzle, glass reinforced plastic nozzle or alloy nozzle.
