Abstract
The utility model discloses a spray pipe device comprising a spray main pipe, spray branch pipes, nozzle short pipes and nozzles, wherein the spray branch pipes are connected on the spray main pipe; and the nozzles are connected at tail ends of the nozzle short pipes and uniformly distributed in the spray plane. The device is characterized in that spray small branch pipes of equal height are respectively connected at lower ends of the spray branch pipes; and the spray short pipes are arranged at lower ends of the spray small branch pipes. Compared with the prior art, the spray pipe device disclosed by the utility model has the advantages that the spray small branch pipes of equal height are arranged to ensure that the nozzles can be effectively guided from the plane of the spray main pipe to the plane below the spray layer supporting beam, so that the problem that the supporting beam is scoured and perforated, which frequently occurs in a desulfurization system, is avoided and in the meantime, slurry is uniformly sprayed from the nozzles which are uniformly distributed in the same plane and flue gas is uniformly absorbed; and therefore, the absorptivity of flue gas SO2 can be effectively increased and the stable and efficient operation of the desulfurization system is greatly promoted.
Description
Technical field
The utility model relates to and a kind ofly for wet method fume desulfurizing system (WFGD) or a kind of can avoiding of similar field, shower brace summer is washed away and can improve flue gas SO
2the spray pipe device absorbing.
Background technology
Spray pipe device is the visual plant of absorption system in wet method fume desulfurizing system (WFGD).After the import of desulphurization system Central Plains flue gas self-absorption tower flue gas enters in absorption tower, the atomization slurry spraying downwards with spraying layer fully contacts, SO
2with the CaCO in atomization slurry
3chemical reaction occurs and by slurries, absorbed, reactant is settled down to the oxidation pond at the bottom of tower with slurries, and oxidation is discharged.
Spray pipe device comprises that spray supervisor, spray arm, nozzle connect short tube, spraying layer brace summer, nozzle.Lime stone slurry is squeezed into spray supervisor by circulating pump from oxidation pond, through spray arm, nozzle, after slurry spraying with flue gas in SO
2reaction, absorbs the SO in flue gas
2, make flue gas reach discharge standard.
System will guarantee the desulfurization degree of desulphurization system, will guarantee exactly the uniformity of arrangement of nozzles, and guarantees that the actual coverage rate of nozzle is greater than 170%.The uniformity of arrangement of nozzles refers to that between every layer of nozzle, spacing is even; The actual coverage rate of nozzle refers to the area sum at slurries 1 meter of under nozzle and the ratio of uptake zone, absorption tower area of section of conplane nozzle ejection.
The shower in known this field is furnished with two kinds at present, and a kind of is that spray arm is stretched out in spray supervisor both sides, and spray arm both sides are stretched out nozzle short tube again, connect nozzle; Spray supervisor stretches out a spray arm in both sides, and spray arm downside stretches out length different spray nozzles short tube, connects nozzle.
Because the increase of spray flux random groups increases, spray supervisor caliber increases thereupon, and the cross section of spray brace summer increases with the increase on absorption tower.Front a kind of layout, nozzle, due to the restriction of structure, cannot guarantee nozzle being evenly arranged on horizontal plane, the slurries of nozzle ejection simultaneously can wash away shower brace summer, must serve as a contrast the very high alloy of cost and prevent from washing away on shower brace summer; Rear a kind of layout is not because nozzle is or not a plane, even if nozzle is uniform, in next plane of nozzle, because the area of nozzle ejection is different, nozzle coverage rate can not reach the actual coverage rate that nozzle calculates, and spray is inhomogeneous in the vertical direction.What spray is inhomogeneous, and flue gas will be escaped in place low from spray coverage rate, that pressure is low, reduces the desulfurization degree of desulphurization system.
Summary of the invention
technical problem:technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of uniform spraying layer nozzle is provided, and avoids brace summer to wash away, and improves SO in flue gas
2the spray pipe device absorbing.
technical scheme:the utility model solves the technical scheme that its technical problem adopts:
A kind of spray pipe device, comprise spray supervisor, spray arm, nozzle short tube and nozzle, described spray arm is connected on described spray supervisor, described nozzle is connected to the end of nozzle short tube and uniform in plane at spray, it is characterized in that: in described spray arm lower end, be also connected with respectively contour spray smaller branch pipe, described nozzle short tube is arranged on the lower end of described spray smaller branch pipe.
Described spray arm is connected to described spray supervisor's both sides, in described spray supervisor lower end, is also provided with spray smaller branch pipe.
Described nozzle short tube is arranged on the both sides of described spray smaller branch pipe lower end.
The utility model spray equipment, spray arm is stretched out in every layer of spraying layer spray supervisor both sides, and spray arm (supervisor) downside stretches out contour spray smaller branch pipe, and smaller branch pipe both sides are stretched out nozzle short tube again, connect nozzle.Uniform nozzle also connects by contour spray smaller branch pipe, guarantees that nozzle is even at same plane slurry spraying; Avoid the washing away of spraying layer brace summer simultaneously, eliminate system security of operation hidden danger.
beneficial effect:arranging of the utility model shower arrangement utilizing spray smaller branch pipe guided to nozzle spray supervisor, below spraying layer brace summer, solved the restriction due to structure, the inhomogeneities of the arrangement of nozzles causing.Contour smaller branch pipe has guaranteed that same spraying layer nozzle vertical direction, in same level, has effectively guaranteed the actual coverage rate of nozzle and the uniformity of nozzle ejection, avoid flue gas to escape, and the gas-liquid contact area having increased, has promoted SO
2absorption reaction, has improved SO in flue gas
2absorption efficiency.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
As Fig. 3, shown in Fig. 4 and Fig. 5, the utility model spray equipment is fixed by spraying layer brace summer, spray equipment comprises spray supervisor 1, spray arm 2, spray smaller branch pipe 3, nozzle short tube and nozzle 5, spray supervisor 1 presses the uniform principle of nozzle 5, from spray supervisor 1 both sides, by certain spacing, stretch out spray arm 2, spray arm 2 and spray supervisor 1 downside stretch out contour spray smaller branch pipe 3 by certain spacing (with the uniform principle of nozzle), the height of spray smaller branch pipe 3 is advisable to have certain safe distance bottom the jet atomization streamline of nozzle 5 and spraying layer brace summer, avoid washing away.According to the layout of nozzle 5, both sides or a side of spray smaller branch pipe 3 bottoms are stretched out nozzle short tube, connect nozzle 5.
The utility model spray equipment, moves to spraying layer brace summer 4 by spray smaller branch pipe 3 from spray supervisor 1 plane nozzle ejection plane.
