Description
Technical field
The utility model relates to a kind of small particle diameter desulfurization nozzle.
Background technology
Along with development and the extensive use of Wet Flue Gas Desulfurization Technology, the high-efficient atomizing of desulfurization medium is the focus that people pay close attention to always.Atomizing type conventional at present has mechanical atomization, medium atomization (steam or air etc.), machinery+medium atomization, effervescent atomization etc., explore more efficient, more economical, the more applicable atomization technique of exploitation and become raising desulfuration efficiency, reduce the important topic of desulphurization cost.
Generally adopt atomizing nozzle in current desulfuration spray tower, this type of nozzle atomization effect is poor, needs repeatedly to extract slurry spraying to improve the utilization rate of slurries by slurry circulating pump, and needed for desulfurizer, number of nozzle is more, and therefore desulphurization cost is higher.Therefore in conjunction with prior art, on the basis of medium atomization nozzle, the principle of Appropriate application Laval-cavity nozzle, works out a kind of small particle diameter desulfurization nozzle and has great importance.
Utility model content
The purpose of this utility model is to provide the small particle diameter desulfurization nozzle that a kind of structure is simple, can produce small particle diameter atomized particles.
In order to reach above-mentioned purpose, the utility model adopts following technical scheme:
A kind of small particle diameter desulfurization nozzle, comprise flue and slurry pipe, the injection point pipe be obliquely installed that described slurry pipe comprises horizontally disposed serum outlet pipe and is connected with serum outlet pipe, the outlet of described flue is set in described serum outlet pipe, the outlet of described flue communicates with the outlet of described serum outlet pipe, and the gas passage in described flue broadens after first narrowing gradually from the inlet to the outlet gradually.
Further, the outlet diameter of described gas passage is less than the inlet diameter of gas passage.
Further, serum outlet pipe and described flue coaxial line.
Further, the axis of injection point pipe and the axis at described gas channel inlet place are 45 ° of-75 ° of angles.
Further, the outlet of serum outlet pipe is inverted taper.
Further, the porch of flue is connected with gas pipeline by flange.
Further, the porch of injection point pipe is connected with fluid pipeline by flange.
The beneficial effects of the utility model are:
1) slurry channels is arranged at the outside of gas passage, realizes the form of jet expansion water bag gas.
2) small particle diameter desulfurization nozzle exit, slurries, under the double atomization effect of swiftly flowing gas and shock wave, produce the atomized particles of particle diameter 50-200 μm.
3) small particle diameter desulfurization nozzle is applied in wet desulfurization system, increases the specific area of reacting slurry and smoke contacts, improves desulfuration efficiency, reduces desulfurization energy consumption.
4) small particle diameter desulfurization nozzle compact conformation, stable, with low cost, can reduce the newly-built and improvement cost of desulphurization system, and can reduce desulphurization system operating cost, is suitable for the projects such as the newly-built and transformation of desulphurization system, is applicable to very much applying.
Accompanying drawing explanation
Fig. 1 is structure principle chart of the present utility model;
Wherein, 1, gas passage, 2, slurry channels, 3, injection point pipe, 4, serum outlet pipe, 5, flue, 6, gas passage throat, 7, flange.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, clear, complete description is carried out to the technical scheme in the utility model embodiment.
As shown in Figure 1, a kind of small particle diameter desulfurization nozzle, comprise flue 5 and slurry pipe, described slurry pipe comprises the injection point pipe 3 be obliquely installed that horizontally disposed serum outlet pipe 4 is communicated with serum outlet pipe 4, the outlet of described flue is set in described serum outlet pipe 4, the outlet of described flue communicates with the outlet of described serum outlet pipe 4, and the gas passage 1 in described flue broadens after first narrowing gradually from the inlet to the outlet gradually.
Further, the outlet diameter of gas passage 1 is less than the inlet diameter of gas passage 1.
Further, serum outlet pipe 4 and described flue 5 coaxial line.
Further, the axis of injection point pipe 3 and the axis of described gas passage 1 porch are 45 ° of-75 ° of angles.
Further, the outlet of serum outlet pipe 4 is tapered.
Further, the porch of flue 5 is connected with gas pipeline by flange.
Further, the porch of injection point pipe 3 is connected with fluid pipeline by flange 7.
Operation principle of the present utility model is: gas velocity increase, pressure drop in gas passage 1 contraction section, at place of gas passage throat 6, the speed of gas reaches local velocity of sound, then along with gas passage 1 broadens gradually, gas velocity continues to be increased to supersonic speed, and pressure durations declines, due to the impact of environment back pressure, produce shock wave in gas passage 1 exit, gas is risen at gas path exit port place gas pressure, and gas velocity is sharply down to subsonic speed scope.
Because serum outlet pipe 4 is arranged at the outside of flue 5, therebetween slurry channels 2 is defined, the outlet of serum outlet pipe 4 and the outlet of slurry channels 2, this exports tapered contraction mouth, slurries enter slurry channels 2 by injection point pipe 3, flow to slurry channels 2 exit, under the double atomization effect of swiftly flowing gas and shock wave, produce the atomized particles of particle diameter 50-200 μm in the exit of serum outlet pipe 4, realize the high-efficient atomizing of slurries.
The above; be only specific embodiments of the present utility model; but protection domain of the present utility model is not limited thereto, any do not run counter to Spirit Essence of the present utility model and principle under the change done or replacement, be included within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
