Slurries conveying oxygen or air of the system into desulphurization tower slurry pool are sent, the calcium sulfite during oxygen is interior with slurries, which reacts, generates sulphur
Sour calcium completes the chemical reaction of desulfurization second step, avoids sulfur dioxide gas polluting environment.The prior art is defeated to desulphurization tower slurry pool
Send oxygen using pipeline and wind turbine, pipeline stretches in slurries, and oxidation wind (is generally directly used air as oxygen by wind turbine
Change wind) by pipeline slurries bottom, oxidation wind bubble ands slurry reaction while rising；In order to enable oxidation wind bubble
Distribution is more uniformly distributed, and blender is generally arranged in desulphurization tower slurry pool, and blender forms liquid flowing, oxygen inside slurries
Change general mood and steeps the horizontal proliferation with working fluid.Oxidation wind bubble caused by the oxidation wind transport system of the prior art compared with
Greatly, the gross area of oxidation wind bubble and slurry liquid contacts is small, and oxidation wind is not enough with slurry reaction, the utilization rate of oxidation wind compared with
It is low.
Utility model content
The technical problems to be solved in the utility model is that general mood is aoxidized caused by the oxidation wind transport system of the prior art
Steep larger, the gross area of oxidation wind bubble and slurry liquid contacts is small, and oxidation wind is not enough with slurry reaction, the utilization rate of oxidation wind
Relatively low problem.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of array oxidation wind delivery system
System, including main pipeline, subtube, wind turbine and blender；
Main pipeline is mounted on the pool wall of desulphurization tower slurry pool, and main pipeline gos deep into the slurries of desulphurization tower slurry pool；Supervisor
An end installation at least subtube, the subtube in road is provided with multiple nozzles along its length direction；Wind turbine is into main pipeline
Blast oxidation wind；Blender is mounted on the pool wall of desulphurization tower slurry pool.
Further, the subtube is horizontally disposed, and the nozzle on subtube is downward；The blade direction of blender is horizontal
The blender that either slightly has a down dip forms the liquid stream of horizontal or slight downdip direction flowing in slurries；Horizontal subtube makes
The fluid pressure that all nozzles are born on subtube is almost the same, nozzle interior air pressure is also almost the same, thus all sprays
The size for the oxidation wind bubble that mouth generates is also almost the same；All oxidation wind bubbles are on fluid pathways after its formation, warp
The rolling action of liquid stream and diffuse in entire slurries, be conducive to oxidation wind and fully reacted with slurries.
Further, the vertical height of the subtube is higher than blender, and the liquid stream for the flowing that blender generates is located at spray
The lower section of mouth；This design neither influences the diffusion of oxidation wind bubble, also slightly can raise entire subtube in slurries
Highly, the fluid pressure that nozzle is born is reduced, and then reduces power of fan.
Further, the gross area of all nozzles is less than the sectional area of main pipeline, ensures the performance of nozzle air current.
Further, the main pipeline is fixed by the bracket the pool wall in desulphurization tower slurry pool, the main pipeline and is in charge of
Road is made by corrosion-resistant stainless steel material.
Advantageous effect：(1) the array oxidation wind transport system of the utility model is generated using multiple nozzles of subtube
A large amount of smaller oxidation wind bubbles, increase the contact area of oxidation wind bubble and slurries, while also increasing oxidation wind
Residence time (the minute bubbles rate of climb liquid in be less than the air pocket rate of climb liquid in) of the bubble in slurries,
Be conducive to oxidation wind bubble more fully to react with slurries, improve the utilization ratio of oxidation wind, reaches identical oxidation effectiveness
In the case of, the oxidized input air of demand is greatly lowered, while reducing oxidation fan power of motor, reaches energy-efficient purpose.(2) originally
The subtube that the array oxidation wind transport system of utility model uses is arranged horizontally, height one of all nozzles in slurries
It causes, the fluid pressure of all nozzles is in the same size so that the oxidation wind bubble size that all nozzles generate is almost the same, whole to starch
Oxidation wind bubble in liquid is more evenly dispersed.(3) subtube that the array oxidation wind transport system of the utility model uses
Nozzle downward, the height of subtube is more than the height of blender, compared to traditional equipment, the height of the nozzle of the utility model
Higher is spent, the fluid pressure smaller that nozzle is born advantageously reduces power of fan.
