Abstract
The invention relates to a nozzle structure for an adsorption tower of a desulphurization unit, which relates to a flue gas desulphurization unit in the technical field of environmental protection. The nozzle structure comprises a nozzle and a connecting piece which is enwound and connected with a pipeline of a spraying layer. The nozzle structure is characterized in that the bottom end of the nozzle is provided with a plurality of positioning lugs with positioning holes. The inside and the outside diameters of the lower section of the connecting piece are same as those of the pipeline of the spraying layer. The top end of the connecting piece is a round tray which is provided with necks of which the amount and the shapes are matched with those of the positioning lugs of the nozzle. When the positioning lugs of the nozzle are screwed in the necks, the positioning lugs are fixed by positioning pins which pass through the positioning holes and the round holes on the necks. Compared with the prior art, the nozzle structure is applicable to various desulphurization slurry nozzles, and has the advantages of low cost for the components, convenient installation and inspection, and short construction period.
Description
Technical field
The present invention relates to the flue gas desulfur device of environmental technology field, especially for the slurries nozzle arrangements of thermal power plant desulfurizer absorbing tower.
Background technology
The desulfurization slurry nozzle is the vitals in flue gas desulphurization system (FGD) absorption tower, nozzle and pipeline be connected operation important influence to the absorption tower.General desulfurization slurry nozzle connected mode has two kinds at present, and one is that fiberglass (FRP) is intertwined and connected, and another kind is that flange connects.As adopting fiberglass to be intertwined and connected, it is extremely inconvenient that it installs maintenance, particularly when needs dismounting, replacing nozzle, not only need the fiberglass workmen of specialty to construct, and in unloading process easy defective nozzle, long construction period, labour intensity is big, and construction environment is abominable.Though can effectively avoid above-mentioned shortcoming and adopt flange to connect, construction is easy, and the cycle is short, but because connecting bolt must adopt 1.4529 stainless steels or more high-grade material, the buying expenses height.
Summary of the invention
In order to solve the problem that above-mentioned prior art exists, the purpose of this invention is to provide a kind of nozzle arrangements that is used for desulfurizer absorbing tower.It is applicable to various desulfurization slurry nozzles, has that component costs is low, that maintenance is installed is convenient, the characteristics of short construction period.
In order to reach the foregoing invention purpose, technical scheme of the present invention realizes as follows:
A kind of nozzle arrangements that is used for desulfurizer absorbing tower, it comprises nozzle and the connector that is intertwined and connected with the spraying layer pipeline.Its design feature is that described nozzle bottom is provided with a plurality of chucking lugs of band locating hole.The interior external diameter of described connector hypomere is identical with the interior external diameter of spraying layer pipeline.The connector top is a round tray, is provided with the draw-in groove that chucking lug quantity and shape with nozzle are complementary in the pallet.When the nozzle chucking lug rotates into draw-in groove, fix by the alignment pin that passes circular hole on locating hole and the draw-in groove.
In the said nozzle structure, described nozzle adopts carbofrax material, and described connector adopts carborundum or glass-reinforced plastic material, and described alignment pin adopts polypropylene material.
In the said nozzle structure, between described draw-in groove inwall and the chucking lug pad is housed.
In the said nozzle structure, the inwall end face of described draw-in groove is the inclined-plane.
In the said nozzle structure, described chucking lug and draw-in groove are four.
In the said nozzle structure, described nozzle is tangent type nozzle, screw type nozzle or liquid column type nozzle.
The present invention has been owing to adopted said structure, makes nozzle and connector thereof install and overhaul convenient and reliable, is applicable to the installation connection of all kinds desulfurization slurry nozzle absorption tower in.Nozzle and connector material cost are not high, simple in structure, short construction period.
The present invention will be further described below in conjunction with the drawings and specific embodiments.

The specific embodiment
Referring to Fig. 1 to Fig. 6, the connector 2 that the present invention includes liquid column type nozzle 1 and adopt fiberglass to be intertwined and connected with spraying layer pipeline 5, nozzle 1 adopts carbofrax material, and connector 2 adopts carborundum or glass-reinforced plastic material.Nozzle 1 bottom is provided with four chucking lugs 8 of band locating hole 7.The interior external diameter of connector 2 hypomeres is identical with the interior external diameter of spraying layer pipeline 5, and connector 2 tops are round tray.Be provided with the draw-in groove 10 that chucking lug 8 quantity and shape with nozzle 1 are complementary in the pallet, the inwall end face of draw-in groove 10 is the inclined-plane.When nozzle 1 chucking lug 8 rotates into draw-in groove 10, fixing by the alignment pin 3 that passes the employing polypropylene material of circular hole on locating hole 7 and the draw-in groove 10, between draw-in groove 10 inwalls and the chucking lug 8 pad 4 is housed.
When the present invention installed and used, the hypomere with connector 2 docked with spraying layer pipeline 5 earlier, and the outside wall surface of the two is fixedly connected by the mode that fiberglass twines.Chucking lug 8 with nozzle 1 inserts in the draw-in groove 10 of connectors 1 then, and chucking lug 8 is rotated counterclockwise makes rubber sheet gasket 4 be compressed chucking gradually, thereby finishes the fastening and sealing between nozzle 1 and the connector 2.With alignment pin 3 nozzle 1 and connector 2 are fixed at last, prevented the loose or dislocation of nozzle 1.
When the present invention overhauls, extract alignment pin 3 earlier, the nozzle 1 that turns clockwise screws out chucking lug 8 in draw-in groove 10, and nozzle 1 can be dismantled easily.
The present invention is not only applicable to liquid column type nozzle, simultaneously tangent type nozzle (as shown in Figure 7), screw type nozzle and other various types of desulfurization slurry nozzles also is suitable for.
