Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
As shown in Figure 1, a kind of blender catalyst charging device, comprise the first feed pipe 1, second feed pipe 2 and catalyst commissioning pipe 3, wherein the first feed pipe 1 is for carrying acetic acid steam, and the second feed pipe 2 is for carrying diammonium hydrogen phosphate catalyst solution.
Mixer tube 6 is fixed with cover flange 8 by the shell flange 7 be arranged on cylinder body outer wall, and fix the first feed pipe 1 at the home position of cover flange 8, acetic acid steam enters mixer tube 6 by the first feed pipe 1.The outer wall of the first feed pipe 1 is fixed the second feed pipe 2, second feed pipe 2 is arranged by certain angle of inclination, catalyst commissioning pipe 3 is provided with in the second feed pipe 2, the termination, top of catalyst commissioning pipe 3 and the top of the second feed pipe 2 are fixed by mounting flange 9, the bottom of catalyst commissioning pipe 3 is stretched in the first feed pipe 1, and diammonium hydrogen phosphate catalyst solution is conveyed into mixer tube 6.
Bracing or strutting arrangement is fixed with in the tip position of the bottom of catalyst commissioning pipe 3, bracing or strutting arrangement comprises two supports 4, the termination, bottom of support 4 one end and catalyst commissioning pipe 3 is welded and fixed, and the inwall of the other end and the first feed pipe 1 overlaps, and two supports 4 angle is in the horizontal direction 180 °.The bottom of catalyst commissioning pipe 3 is enable to be overlapped on the inwall of the first feed pipe 1 by two supports 4, thus make catalyst commissioning pipe 3 change simply supported beam form into by original cantilever beam form, can not produce when the first feed pipe 1 acetic acid steam flow rate is larger and rock, effectively avoid the fracture of catalyst commissioning pipe 3.
Bracing or strutting arrangement can also be three supports 4, and the termination, bottom of every root support 4 one end and catalyst commissioning pipe 3 is welded and fixed, and the inwall of the other end and the first feed pipe 1 overlaps, and every two supports 4 angle is in the horizontal direction 120 °.Adopt three supports 4 that overlap joint can be made more firm.Support 4 should not arrange too much, and too much support 4 can affect the charging effect of the first feed pipe 1.
Support 4 and the first feed pipe 1 overlap but not are welded and fixed, because the acetic acid vapor (steam) temperature of the first feed pipe 1 reaches 300-400 DEG C, because acetic acid vapor (steam) temperature is higher, cause solder joint to rupture so support 4 can produce to expand with heat and contract with cold, and easily cause the corrosion of the first feed pipe 1 inwall and cover flange 8 after solder joint fracture.
The outer diameter of catalyst commissioning pipe 3 is equal with the inner diameter of the second feed pipe 2, by the interference fit of catalyst commissioning pipe 3 and the second feed pipe 2 support, make catalyst commissioning pipe 3 dilation connect in the second feed pipe 2, the cantilever beam of catalyst commissioning pipe 3 shortens, its cantilever beam length is only the part stretching into the first feed pipe 1, if bracing or strutting arrangement damages and cannot support for catalyst commissioning pipe 3, so because the shorter catalyst commissioning pipe 3 of also can effectively avoiding of cantilever beam of catalyst commissioning pipe 3 ruptures.
The termination that catalyst commissioning pipe 3 stretches into first feed pipe 1 one end is arranged on the pipe axial location of the first feed pipe 1, the discharging direction of catalyst commissioning pipe 3 is parallel with the discharging direction of the first feed pipe 1, make the shaft core position of catalyst solution from the position that catalyst commissioning pipe 3 flows out at the first feed pipe 1, and the discharging direction after catalyst solution flows out from the first feed pipe 1 from the discharging direction after catalyst commissioning pipe 3 flows out with acetic acid steam is parallel, is conducive to mixing of catalyst and acetic acid steam.
As shown in Figure 1, due in the present embodiment, second feed pipe 2 and catalyst commissioning pipe 3 are arranged by certain angle of inclination, and there is certain angle between the first feed pipe 1, the acetic acid steam flowed out from the first feed pipe 1 and the catalyst flowed out from catalyst commissioning pipe 3 flowing to when mixing not parallel, have impact on mixed effect, so in the present embodiment, one end that catalyst commissioning pipe 3 stretches into the first feed pipe 1 bends in the pipe axial location of the first feed pipe 1, catalyst commissioning pipe 3 after bending is along the pipe Axis Extension of the first feed pipe 1, namely catalyst commissioning pipe 3 bends the axis of rear section and the pipe dead in line of the first feed pipe 1.Catalyst solution is flowed out by this structure from catalyst commissioning pipe 3 after, be not only positioned at the shaft core position of the first feed pipe 1, also parallel with the discharging direction of the acetic acid steam flowed out from the first feed pipe 1, be conducive to mixing of catalyst and acetic acid steam.
Bracing or strutting arrangement also serves certain booster action at this, ensure that catalyst commissioning pipe 3 does not rock by bracing or strutting arrangement, enables the termination of catalyst commissioning pipe 3 remain on the pipe axial location of the first feed pipe 1.
The part that catalyst commissioning pipe 3 bends rear extension stretches in mixer tube 6, stretches on the termination in mixer tube 6 be provided with fog-spray nozzle 5 at catalyst commissioning pipe 3, and the spray direction of fog-spray nozzle 5 is identical with the discharging direction of the first feed pipe 1.
In sum, owing to arranging bracing or strutting arrangement, make catalyst commissioning pipe 3 not easy fracture, rupture by avoiding catalyst commissioning pipe 3, make catalyst solution when entering blender, torrent impact can not be carried out to the first feed pipe 1 and cover flange 8, and not rupture due to catalyst commissioning pipe 3 thus to make to mix, the mixing of acetic acid steam and catalyst is made to reach the uniformity, thus formation ammonium phosphate, avoiding corroding cover flange 8 because mixing uneven formation phosphoric acid, greatly improving the service life of cover flange 8.Bent by the pipe axial location of catalyst commissioning pipe 3 at the first feed pipe 1, and along pipe Axis Extension, make catalyst solution after catalyst commissioning pipe 3 outflow, be positioned at the shaft core position of the first feed pipe 1, and it is parallel with the acetic acid steam steam flow direction of the first feed pipe 1, be conducive to mixing of catalyst solution and acetic acid steam, improve mixed effect.
As mentioned above, plan content given by reference to the accompanying drawings, can derive similar technical scheme.In every case be the content not departing from technical solutions of the utility model, any simple modification done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
