Described EP rubbers glue solution nozzle, it is characterised in that the glue pipeline and vapor pipeline center axle
It is identical.
Described EP rubbers glue solution nozzle, it is characterised in that the necking includes glue outlet, steam outlet, institute
State glue outlet and be provided with an angle of throat, an angle of flare, the angle of flare is close to the glue outlet ends.
Described EP rubbers glue solution nozzle, it is characterised in that the angle of throat, angle of flare are the glue exits
Glue duct wall is convexed to form.
Described EP rubbers glue solution nozzle, it is characterised in that the diameter dimension of glue outlet several millimeters with
It is interior.
Described EP rubbers glue solution nozzle, it is characterised in that direction where the steam entry of the vapor pipeline
It is vertical with the axial direction of nozzle.
Compared with the prior art, the good result obtained using the utility model is：
Vapor and glue are conducted heat by glue tube wall A, i.e. vapor heating glue, and volume is swollen after glue is heated
It is swollen, and due to angle of throat a presence, glue is quickly sprayed in glue exit, due to angle of flare b presence, from glue
Outlet spray glue there is certain diffusivity so that the glue of ejection and with its around spray steam it is tangent, greatly
Cutting and peptizaiton of the vapor to glue are improved, meanwhile, vapor is directly contacted in nozzle exit with glue, is improved
Glue in solvent naphtha removal efficiency.Obtained particle size analysis is condensed between 1.0~3.0mm, and solvent naphtha is residual in micelle
Remaining content is less than 0.5%.

Embodiment
The EP rubbers glue solution nozzle that the utility model is provided, is connected with condensing field, it is characterised in that the nozzle edge is solidifying
In poly- kettle radial direction insertion condensing field, the nozzle is sleeve structure, and the nozzle entrance is located at outside condensing field, and outlet is located at
In condensing field, the jet expansion is necking.Nozzle is cylinder from entrance to exporting preceding, and jet expansion is cone, is used
It is glue pipeline in two layers of sleeve structure, internal layer, the interlayer AB between outer layer and internal layer is vapor pipeline, glue pipeline is provided with
Glue outlet 3, glue entrance 1, vapor pipeline are provided with steam outlet 4, steam entry, and internal layer is glue tube wall A, outer layer
For vapor tube wall B, the necking includes glue outlet 3, steam outlet 4, and the glue outlet 3 is provided with an angle of throat a, one
Angle of flare b, the angle of flare exports 3 ends close to the glue, and the angle of throat a, angle of flare b are at the glue outlet 3
Glue duct wall convex to form.The glue pipeline vertical with the axial direction of nozzle of direction where vapor entrance
It is identical with vapor pipeline center axle.1 is glue entrance in figure, and 3 be glue outlet；2 be steam entry, and 4 be that water steams
Gas is exported.
Specific implementation process：
The utility model nozzle operationally, nozzle leading portion is inserted in condensing field and installs in place, meanwhile, glue entrance 1
It is connected on glue feeding line, steam entry 2 is connected on vapor feeding line.It is passed through in A layers with certain viscous
Vapor is passed through in the EP rubbers glue of degree, the interlayer AB between outer layer and internal layer, glue is in glue tube wall A to glue
