Description
Technical field
Flue gas denitrification equipment field is the utility model is related to, more particularly to a kind of denitrification apparatus.
Background technology
In SNCR denitration processing procedure, it usually needs higher temperature, to reach the requirement in temperature, part steam power plant
When carrying out SNCR denitration processing to flue gas, selection is directly by liquid medicine spray in boiler.
And most of steam power plants go out during denitration to reduce the situation of liquid medicine reduction boiler internal temperature
It is existing, select to carry out denitration process in the special pipeline of SNCR denitration.However, although this method is preferably maintained in boiler
Higher temperature, but when flue gas passes through pipeline, speed, it is difficult to make the medicine that spray goes out carry out the flue gas discharged out of boiler
More sufficient denitration process.
Utility model content
The purpose of this utility model is to provide a kind of denitrification apparatus, has the advantages of improving SNCR denitration treatment effeciency.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of denitrification apparatus, including tower body, the smoke inlet and outlet flue being arranged on tower body, and be arranged in tower body
Spray assemblies, the smoke inlet are arranged on tower body diagonally downward；Guide is provided with the tower body, the guide includes
Support column and guide plate, the guide plate helical form are arranged at the outside of support column；The spray assemblies include shower and spray
Head is drenched, the spray head is obliquely installed on shower.
It is arranged such, because smoke inlet is sets diagonally downward, after flue gas enters the inside of tower body by smoke inlet, under
The upward spiral diffusion motion of guide plate set upwards along helical form, add the approach of flue gas rising.When spray liquid is from inclining
When being sprayed in the nozzle tiltedly set, the ejection path of spray liquid becomes inclined or circular arc, so as to help to increase spray liquid
Contact between flue gas, and then improve the effect of denitration.
More preferably：The incline direction of the spray head is opposite with the bearing of trend of the termination of guide plate.
Be arranged such, the direction for helping to make spray liquid to spray rise with flue gas helical form it is in opposite direction, so as to increase
Time of contact and abundant degree of the spray liquid of ejection with the flue gas with a part, effectively improve denitration effect.
More preferably：The guide plate is set to lower recess.
It is arranged such, increases the stereovision being oriented to flue gas, the guide plate of downward sunk part is more conducive to make flue gas edge
It forms helical form.
More preferably：Projection is provided with the inwall of the tower body.
It is arranged such, increases surface area, contributes to the surface attachment spray liquid in projection.And when flue gas is constantly upward
During diffusion and transmission, partial fume is thrown toward on the inwall of tower body, and this partial fume and projection are in contact and by
To projection to its certain barrier effect, the time that flue gas contacts with the spray liquid of lug surface is extended, makes flue gas and spray
Leaching liquid occurs preferably to contact and reach preferable denitration.
More preferably：Tilted down on the inwall of the tower body and be provided with block piece, the block piece be arranged at into
The top of mouth.
Be arranged such, after flue gas enters the inside of tower body from smoke inlet, by block piece barrier effect and along resistance
The bearing of trend of block piece enters, and is more conducive to the bearing of trend transmission for making flue gas along guide plate, increases the path of transmission, and then
Extend the time that flue gas contacts with spray liquid.
More preferably：The block piece includes first baffle and the first elastic component, the first baffle and guide plate
Between be provided with gap, one end of first elastic component is arranged on first baffle and the other end is arranged at the inwall of tower body
On.
It is arranged such, first baffle is hinged on inwall, and when flue gas promotes first baffle, the first elastic component is stretched,
And reverse active force is produced to first baffle, control flue gas, which enters first, to be reduced first caused by flue gas flow is excessive
Baffle plate is damaged.
More preferably：The block piece includes second baffle and third baffle, is offered on the second baffle slotting
Groove, the third baffle are inserted in slot, and the third baffle is connected by the second elastic component with second baffle.
It is arranged such, when the active force for the flue gas that third baffle is received through, because second baffle, third baffle are
It is obliquely installed, then is easier to make third baffle drive the compression of the second elastic component, and then make its length between the second elastic component contract
It is short.When flue gas flow is excessive, it is not easy to make third baffle and second baffle sustain damage.
More preferably：The bottom of the tower body is provided with outlet, and the support column is provided with inner chamber, the inner chamber
Setting is connected with outlet；Open up jagged on the support column, the breach connects with inner chamber.
Be arranged such, if circulation flue gas it is less and spray liquid it is more when, can pass through breach, inner chamber, outlet receive
Collect unnecessary spray liquid, reclaim and recycled after processing, help to reduce processing cost.
In summary, the utility model has the advantages that：
By the collective effect of guide and the spray head being obliquely installed, help to make flue gas constantly upward along helical form
Diffusion, while it is sprayed again, so that overall have more preferable SNCR denitration effect.
