Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
As shown in Figure 1, the first feed pipe 1, the second feed pipe 2, catalyst commissioning pipe 3, holder 4, fog-spray nozzle 5, mixer
Cylinder 6, shell flange 7, cover flange 8, mounting flange 9.
Specific implementation mode
Present invention is further described in detail with specific implementation mode below in conjunction with the accompanying drawings：
As shown in Figure 1, a kind of mixer catalyst charging device, including the first feed pipe 1, the second feed pipe 2 and catalysis
Agent commissioning pipe 3, wherein the first feed pipe 1 is for conveying acetic acid steam, the second feed pipe 2 is for conveying diammonium hydrogen phosphate catalyst
Solution.
Mixer tube 6 is fixed by the shell flange 7 being arranged on cylinder body outer wall with cover flange 8, in cover flange 8
Center location fix the first feed pipe 1, acetic acid steam passes through the first feed pipe 1 and enters mixer tube 6.In the first feed pipe
The second feed pipe 2 is fixed on 1 outer wall, the second feed pipe 2 is arranged by certain angle of inclination, is provided in the second feed pipe 2
Catalyst commissioning pipe 3, the top end of catalyst commissioning pipe 3 and the top of the second feed pipe 2 are fixed by mounting flange 9, are urged
The bottom end of agent commissioning pipe 3 is stretched into the first feed pipe 1, and diammonium hydrogen phosphate catalyst solution is conveyed into mixer tube 6.
Tip position in the bottom end of catalyst commissioning pipe 3 is fixed with support device, and support device includes two holders 4,
4 one end of holder and the bottom end end of catalyst commissioning pipe 3 are welded and fixed, the inner wall overlap joint of the other end and the first feed pipe 1, two
The angle of holder 4 in the horizontal direction is 180 °.The bottom end of catalyst commissioning pipe 3 is set to be overlapped on by two holders 4
On the inner wall of one feed pipe 1, to make catalyst commissioning pipe 3 be changed to simply supported beam form by original cantilever beam form, first
Shaking is not will produce in the case that 1 acetic acid steam flow rate of feed pipe is larger, effectively avoids the fracture of catalyst commissioning pipe 3.
Support device can also be that three holders 4, every 4 one end of holder and the bottom end end of catalyst commissioning pipe 3 weld
Fixed, the inner wall of the other end and the first feed pipe 1 overlaps, and the angle of every two holders 4 in the horizontal direction is 120 °.Using three
Root holder 4 can make overlap joint more secured.Holder 4 should not be arranged excessively, and excessive holder 4 can influence the charging of the first feed pipe 1
Effect.
Holder 4 is overlapped rather than is welded and fixed with the first feed pipe 1, is because the acetic acid vapor (steam) temperature of the first feed pipe 1 reaches
To 300-400 DEG C, since acetic acid vapor (steam) temperature is higher, solder joint is caused to be broken so holder 4 will produce to expand with heat and contract with cold, and solder joint
The corrosion of 1 inner wall of the first feed pipe and cover flange 8 is easily caused after fracture.
The outer diameter of catalyst commissioning pipe 3 is equal with the inner diameter of the second feed pipe 2, passes through catalyst commissioning pipe 3
With the interference fit of 2 holder of the second feed pipe, the expansion of catalyst commissioning pipe 3 is set to be connected in the second feed pipe 2, catalyst feeds intake
The cantilever beam of pipe 3 shortens, and cantilever beam length is only to stretch into the part of the first feed pipe 1, if support device damage can not be
Catalyst commissioning pipe 3 is supported, then can also effectively avoid catalyst since the cantilever beam of catalyst commissioning pipe 3 is shorter
Commissioning pipe 3 is broken.
The end that catalyst commissioning pipe 3 stretches into 1 one end of the first feed pipe is arranged in the pipe axis position of the first feed pipe 1
It sets, the discharging direction of catalyst commissioning pipe 3 is parallel with the discharging direction of the first feed pipe 1, and catalyst solution is made to be thrown from catalyst
Expects pipe 3 flow out position the first feed pipe 1 shaft core position, and catalyst solution from catalyst commissioning pipe 3 outflow after
Discharging direction is parallel from the discharging direction after the outflow of the first feed pipe 1 with acetic acid steam, is conducive to catalyst and acetic acid steam
Mixing.
As shown in Figure 1, by this present embodiment, the second feed pipe 2 and catalyst commissioning pipe 3 are set by certain angle of inclination
It sets, there are certain angle between the first feed pipe 1, the acetic acid steam flowed out from the first feed pipe 1 feeds intake with from catalyst
The catalyst that pipe 3 flows out flows to not parallel in mixing, affects mixed effect, so in the present embodiment, catalyst is thrown
One end that expects pipe 3 stretches into the first feed pipe 1 is bent in the pipe axial location of the first feed pipe 1, and the catalyst after bending feeds intake
Pipe 3 extends along the pipe axis of the first feed pipe 1, i.e., the axis and the first feed pipe 1 of part after the bending of catalyst commissioning pipe 3
Pipe axis overlap.Make catalyst solution after the outflow of catalyst commissioning pipe 3 with this configuration, is not only located at the first feed pipe
1 shaft core position, it is also parallel with the discharging direction of acetic acid steam flowed out from the first feed pipe 1, be conducive to catalyst and acetic acid
The mixing of steam.
Support device also acts certain booster action herein, ensure that catalyst commissioning pipe 3 not by support device
It shakes, the end of catalyst commissioning pipe 3 is enable to be maintained at the pipe axial location of the first feed pipe 1.
The part that catalyst commissioning pipe 3 extends after bending is stretched into mixer tube 6, is stretched into catalyst commissioning pipe 3 mixed
Fog-spray nozzle 5, the discharging direction phase in the spray direction and the first feed pipe 1 of fog-spray nozzle 5 are provided on end in clutch cylinder 6
Together.
In conclusion since support device is arranged, keep catalyst commissioning pipe 3 not easy to break, by avoiding catalyst from feeding intake
Pipe 3 is broken, and makes catalyst solution when entering mixer, will not carry out torrent impact to the first feed pipe 1 and cover flange 8,
And since catalyst commissioning pipe 3 is not broken to make to be uniformly mixed so that the mixing of acetic acid steam and catalyst reaches uniform
Degree avoids corroding cover flange 8 because mixing uneven formation phosphoric acid, greatly improves envelope to form ammonium phosphate
The service life of head flange 8.Pipe axial location by catalyst commissioning pipe 3 in the first feed pipe 1 is bent, and along pipe axis
Line extends, and so that catalyst solution is located at the shaft core position of the first feed pipe 1 after the outflow of catalyst commissioning pipe 3, and with first
The acetic acid steam steam flow direction of feed pipe 1 is parallel, is conducive to the mixing of catalyst solution and acetic acid steam, improves mixing effect
Fruit.
As described above, the plan content in conjunction with given by attached drawing, can derive similar technical solution.In every case it is not de-
Content from technical solution of the present invention, according to the technical essence of the invention to made by above example it is any it is simple modification, etc.
With variation and modification, in the range of still falling within technical solution of the present invention.
