Specific implementation mode
It is described in further detail below by specific embodiment and in conjunction with attached drawing to the present invention.
As shown in Figure 1, described in the embodiment of the present invention being a kind of attachment device of desulfurization sprayed slurry pipeline, the device packet
It includes：
Sprayed slurry GRP pipe flange 3 in desulfuration absorbing tower, with sprayed slurry glass reinforced plastic pipe in desulfuration absorbing tower
The end in road 1 is fixedly connected；
Desulfuration absorbing tower side flange 2 is fixedly connected with desulfuration absorbing tower wall；
Slurry pipe Dow process orchid 4 outside desulfuration absorbing tower is fixedly connected with 5 end of slurry pipe road outside desulfuration absorbing tower；
Slurry pipe Dow process orchid 4 is respectively arranged on spray in desulfuration absorbing tower outside desulfuration absorbing tower side flange 2 and desulfuration absorbing tower
Drench the both sides of slurries GRP pipe flange 3；
Sprayed slurry glass in desulfuration absorbing tower side flange 2, desulfuration absorbing tower outside slurry pipe Dow process orchid 4 and desulfuration absorbing tower
Glass steel conduit 3 specifications of flange are identical, and slurry pipe Dow process orchid 4 and de- outside desulfuration absorbing tower side flange 2, desulfuration absorbing tower
3 three of sprayed slurry GRP pipe flange is threadedly coupled by bolt 6 and nut 7 in sulphur absorption tower.
Sprayed slurry GRP pipe flange 3 in desulfuration absorbing tower is set to desulfuration absorbing tower side flange 2 in the present invention
With the centre of slurry pipe Dow process orchid outside desulfuration absorbing tower 4, and three kinds of flanges are selected into same specifications, by desulfuration absorbing tower side method
Connection in orchid 2, desulfuration absorbing tower outside slurry pipe Dow process orchid 4 and desulfuration absorbing tower on sprayed slurry GRP pipe flange 3
Hole matches correspondence one by one, finally by screw thread by three kinds of flanged joints together, it is final to realize sprayed slurry in desulfuration absorbing tower
Outside GRP pipe and desulfuration absorbing tower slurry pipe road connect and desulfuration absorbing tower in sprayed slurry GRP pipe and take off
Sulphur absorption tower connects.Instead of sprayed slurry GRP pipe flange 3 in two desulfuration absorbing towers is used in the prior art, realize
In desulfuration absorbing tower outside sprayed slurry GRP pipe and desulfuration absorbing tower slurry pipe road connect and desulfuration absorbing tower in spray
Leaching slurries GRP pipe is connected with desulfuration absorbing tower.The design can make sprayed slurry glass reinforced plastic pipe Dow process in desulfuration absorbing tower
The power of blue 3 both sides is transmitted with position, only plays the role of transmission and connection.And it is sprayed in two desulfuration absorbing towers in the prior art
The mode that slurries GRP pipe flange 3 connects can make sprayed slurry GRP pipe flange 3 in two desulfuration absorbing towers respective
Independent stress, there are certain distances between sprayed slurry GRP pipe flange 3 in two desulfuration absorbing towers, in addition desulfurization absorbs
The impact force and pipeline itself of sprayed slurry GRP pipe and desulfuration absorbing tower outside slurry pipe road inside slurries in tower
The influence of amount of deflection or moment of flexure can make in desulfuration absorbing tower sprayed slurry GRP pipe flange 3 by respective impact force and shearing
The influence of power is finally broken to make sprayed slurry GRP pipe flange 3 in desulfuration absorbing tower be worn.And only
The occurrence of such is can avoid using sprayed slurry GRP pipe flange 3 in a desulfuration absorbing tower.
Further, in desulfuration absorbing tower side flange 2 and desulfuration absorbing tower between sprayed slurry GRP pipe flange 3 with
And it is equipped between sprayed slurry GRP pipe flange 3 and desulfuration absorbing tower outside slurry pipe Dow process orchid 4 in desulfuration absorbing tower
Flange gasket.Flange gasket can play flange certain cushioning effect, to extend the service life of flange.
Further, sprayed slurry GRP pipe flange 3 and the mating surface of flange gasket are equipped in desulfuration absorbing tower
Sealing element.Due to sprayed slurry glass reinforced plastic pipe in slurry pipe road outside desulfuration absorbing tower, desulfuration absorbing tower and desulfuration absorbing tower
Road be for conveying desulfurization slurry, therefore need to ensure pipeline connection leakproofness, avoid slurries from leaking, therefore need to be inhaled in desulfurization
The junction of sprayed slurry GRP pipe three is added in receipts tower, desulfuration absorbing tower outside slurry pipe road and desulfuration absorbing tower
Sealing element, such as sealing ring or leakage-proof socket sealing device.
Further, bolt 6 is stud.Since bolt 6 needs to realize that desulfuration absorbing tower side flange 2 and desulfurization absorb
Sprayed slurry GRP pipe flange 3 and desulfurization between sprayed slurry GRP pipe flange 3 and in desulfuration absorbing tower in tower
Two connections between slurry pipe Dow process orchid 4 outside absorption tower, therefore bolt 6 need to select stud.
Further, one end of bolt 6 is at least with there are two nuts 7.In order to make desulfuration absorbing tower side flange 2 and desulfurization inhale
It receives in tower between sprayed slurry GRP pipe flange 3 and sprayed slurry GRP pipe flange 3 and de- in desulfuration absorbing tower
Connection outside sulphur absorption tower between slurry pipe Dow process orchid 4 is more firm, need to add the quantity of nut 7, particular number is according to de-
In sulphur absorption tower outside sprayed slurry GRP pipe 1 and desulfuration absorbing tower in slurry pipe road 5 and two pipelines slurries stream
Amount is common to be determined, if the, slurry flow bigger if size the big needed for nut 7 quantity it is more, otherwise the number of nut 7 can be reduced
Amount.Two nuts 7 are selected in the present embodiment.
Further, in desulfuration absorbing tower side flange 2, desulfuration absorbing tower outside slurry pipe Dow process orchid 4 and desulfuration absorbing tower
Sprayed slurry GRP pipe flange 3 selects high temperature resistant, resistant material.Outside desulfuration absorbing tower, desulfuration absorbing tower
Sprayed slurry GRP pipe is for conveying desulfurization slurry, because of the general temperature of slurries in slurries pipeline and desulfuration absorbing tower
It is all higher, and it has higher acid-base property again, therefore the material of flange then needs to select high temperature resistant and corrosion-resistant material, to
It just can guarantee that flange lasts a long time, ensure the stable operation of sulfur removal technology.
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, any made by repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
