Specific embodiment
As shown in Figure 1, a kind of oxidation air pipeline bilayer cooling device of the embodiment of the present invention, including oxidation air pipe 1
And two groups of cooling devices being arranged side by side on 1 longitudinal direction of oxidation air pipe.For boiler in underload, exhaust gas volumn and sulfur dioxide are all
It can be reduced as boiler at low load changes, oxidation air used is also reduced therewith, therefore, sets two-stage cooling device up and down
Not only can spare easy access each other, but also cooling can be classified and play effect of energy.
Wherein, 1 one end of oxidation air pipe is connected with oxidation fan 4, and 1 other end of oxidation air pipe connects with desulfuration absorbing tower 5
It is logical.
Cooling device specifically includes：
Technique water pipe 2, one end are connected with technique water tank, and 2 other end of technique water pipe is stretched into oxidation air pipe 1, technique
The end of 2 other end of water pipe is fixed with nozzle 3；
Anti- casing 6, is set in 2 outside of technique water pipe, and anti-casing 6 is fixed on oxidation air pipe 1 by flange 7, prevented
6 end of casing extends to 1 outside of oxidation air pipe, and anti-casing 6 and the contact position of oxidation air pipe 1 seal.
Further, anti-6 one end of casing is opening, and opening is fixed on by flange 7 on oxidation air pipe 1；Anti- casing 6
The other end is arc-shaped plug, and the first circular hole is offered on plug, and 2 other end of technique water pipe stretches into oxidation after passing through the first circular hole
In air hose 1.Anti- casing is high temperature resistant casing, with will not cause to deform because of high temperature after oxidation air tube contacts, is caused
Contact position can not seal, and influence the normal operation of oxidation air pipe 1.
Further, the second circular hole is offered on oxidation air pipe 1, plug is connected at the second circular hole, and circular arc is prolonged
It extends to inside oxidation air pipe 1, this design method also allows for technique water pipe 2 convenient for the connection of anti-casing and oxidation air pipe
It stretches into inside oxidation air pipe 1.
Further, the contact position of technique water pipe 2 and nozzle 3 is arranged with lock-on connection 8, and lock-on connection 8 is used for regular worker
Skill water pipe 2 and nozzle 3, and sealing function is played to the contact position of the two.Anti-wearing liner is arranged in lock-on connection 8, into one
Step increases the service life of lock-on connection while improving contact position sealing effect.
Further, technique water pipe 2 is bent downwardly close to 3 one end of nozzle, and the angle of bending is 90 °~120 °, on the one hand
Process water can be facilitated to enter in nozzle, on the other hand can increase the range of ejection.
Further, technique water pipe 2 is equipped with pressure gauge, flowmeter and flow control valve, can be real-time by pressure gauge
The pressure change of technique water pipe is monitored, the changes in flow rate of technique water pipe can be monitored in real time by flowmeter, it is ensured that technique water pipe
Normal operation, while according to cooling demand, the flow of process water is adjusted by flow control valve, and then ensure oxidation air
Temperature-fall period in pipe 1.
Further, nozzle 3 includes：First sleeve, the second casing and jet pipe, first sleeve one end are another with technique water pipe 2
The end connection of one end, first sleeve is interior to be equipped with conduit；Second casing one end is connect with the first sleeve other end, in the second casing
Equipped with the helix tube being connect with end of conduit；Jet pipe one end is connect with the second casing other end, the uniform cloth in jet pipe other end end
Equipped with several nozzle vents.It is to make the water flow bigger of nozzle ejection, more uniform, covering using this design structure
Range is wider.
Further, the diameter of first sleeve is less than the diameter of the second casing, and process water is directly entered second by conduit
In casing, under the eddy flow of helix tube, the flow velocity of process water is adjusted, and will not the process water in conduit directly be flushed to spray
At mouthful, cause pressure at nozzle vent excessive, and then nozzle is caused to damage.
Further, the inlet diameter of jet pipe is more than outlet diameter, and inlet diameter is equal with the diameter of the second casing, this
The design of kind structure is to disperse eddy flow in order to which process water in conduit is uniformly drained into the second casing, if the second casing diameter
It is too small, it may result in that swirl velocity is excessively slow, and then influence the water flow sprayed, influence cooling-down effect.
Further, nozzle vent is horn-like, and the spout of this form can improve the flow of ejection and the model of ejection
It encloses, realizes and preferably spray effect, so that the flow of ejection can be received in oxidation air pipe 1 everywhere, realize uniform
Cooling.
Lime stone slurry and sulfur dioxide optimal reaction temperature are 50 degree or so in desulfuration absorbing tower, and oxidation of the invention is empty
Feed channel formula cooling device enters desulfuration absorbing tower, the oxidation air after cooling after oxidation air is cooled to 50 degree by 110 degree
Oxidation generation gypsum is carried out in desulfurizing tower, while the water balance of entire desulphurization system will not be destroyed, ensures that desulphurization system is long-term
Stable operation extends the service life of desulphurization system.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, that is made any repaiies
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
